This article´s objective is to study the construction techniques of the riverside dwellers in the Amazon rainforest. The studied communities are located in the banks of the Solimões River, and suffer with the constant floods and physical phenomena related to the region environment. An ecosystem of thunderous natural forces, which makes it harder the importation of approaches from other regions as alternatives to the Amazon rainforest. As a method of research and understanding of the problematics, an assessment of the riverside communities in the city of Manacapuru and in two rural communities was carried out, surveying the cultural, social, and environmental characteristics of each community, and surveying the local constructive characteristics, materials and vernacular techniques. In the conclusion, we observed that: the relevance of a joint action to understand the wood and the housing durability, expanding the life cycle of the river buildings and reducing the impact on the rainforest. Regarding thermic comfort, it is important to redeem the bioclimatic techniques of crossed ventilation and to highlight the relevancy of sustainable techniques that work with local materials, such as natural fibers.
This document outlines research hypotheses about urban resilience to drought. It proposes that a city's resilience depends on three factors: 1) antecedent environmental conditions like groundwater levels and quality, 2) the physical water infrastructure, and 3) water governance mechanisms. The research would analyze these factors in major cities on different continents to develop a model for predicting drought resilience. The interdisciplinary study could help increase resilience through practical solutions and advance theory on human-environment interactions.

Indigenous Land Management - Emilie-Jane Ens & Gill TowlerTERN Australia
Indigenous groups in Australia collect extensive ecological data on their lands through long-term monitoring programs and partnerships with universities. This data could help fill gaps in TERN's understanding of biodiversity across the country. For TERN to fully benefit from this data, it needs to recognize the value of Indigenous ecological knowledge and the extent of Indigenous lands, and ensure the prior informed consent of Indigenous groups.
This document proposes a new framework called "anthropogenic biomes" to classify and map global ecological patterns based on human interactions with landscapes rather than just climate. It suggests that ecosystem processes in anthropogenic biomes are primarily a function of human populations and land use, not just climate. The framework identifies 26 different anthropogenic biomes defined by population density, land use, land cover, and other factors. This new approach presents a more realistic picture of the biosphere as intertwined with human systems, with implications for ecology research and education.

Enhancement of fisheries production in open water bodies general principlesSHAHANAS6
Stock enhancement involves limited technological interventions in aquatic ecosystems to increase fisheries production through methods like stocking hatchery-raised fish, habitat modifications, and fertilization. While still experimental, some enhancements have reached commercial scale. They provide high returns with minimal inputs by taking advantage of natural productivity. Enhancements can increase yields, conserve resources, and provide social benefits. However, they may impact wild populations through competition, predation, disease transmission, and genetic interactions if not carefully managed. The effects of releases on genetic structure are also unpredictable and could reduce diversity.

The outcome of the study showed that there is significant relationship existed between resource conflicts and the management of biodiversity conservation in Jozani ecosystem. The study has implications for environmental policy makers. The study concludes by asserting that unemployment, poverty and scarcity of environmental resources are the major causes of conflict, therefore the call is directed to policy makers to strengthen efforts on resolving conflicts by establishing overall strategies such as establishment of participatory community-based approaches to natural resource management, conflict resolution capacity building measures among the stakeholders, amendment of Laws and expansion of employment to reduce direct relying on using natural resource assets for livelihood.
This document discusses predictive habitat modelling of wetland habitats in the Ebro Delta using GIS. It aims to analyze how riverine and marine influences, as well as human alterations like roads and channels, affect habitat distribution. The key variables found to explain habitat occurrence were elevation (for higher-elevation habitats like marshes and rice fields) and distance to the coast (for lower-elevation coastal habitats). While the model predictions matched some habitat maps, other habitats showed mismatches likely due to changes from human development restricting their distribution. The results provide a first step toward modelling habitat distribution in the complex, human-altered landscape of the Ebro Delta.

Defining Vernacular Architecture through Traditional Water Structures- Case S...JIT KUMAR GUPTA
Water and architecture remain largly intertwined integrated and inter-connected. If Water is known as elixir of life, holding key to human living and ensuring quality of life on this planet, water is said to have added value to cities ,architecture and built environment. More than one billion people globally are facing water crisis. Situation remains alarming in the rain deficient areas. Inadequacy in meeting water demand and water resource management have emerged the as greatest ecological, economic, and social challenges of 21st century. Limited availability of potable water on this planet and its rampant misuse calls for evolving appropriate strategies to manage water resource becomes critical. Architecture has been used extensively in India in general and water stressed states of Rajasthan , Gujrat, Maharashtra etc. in particular, to preserve, protect and conserve water for human and animal consumption in both rural and urban areas. Traditional water management structures created in the water deficient areas are known to have contributed extensively to the growth of new vocabulary of architecture besides promoting effective conservation. Over the years these architectural marvels have been misused, abused and neglected by the communities which needs to be leveraged to ensure availability of adequate quantity of quality water for meeting the basic needs of the human beings/ communities/ settlements. Study and evaluation of the water management structures created in the water deficient city of Jhunjhunu (Rajasthan) has revealed the different typologies of structures used in the city to conserve effectively and efficiently water through the involvement of communities. Perpetual neglect and misuse of these water structures, led by urbanization and alternate source of municipal water supply has marginalized these important water resources, which needs to be revived, rehabilitated and put to use to make cities self-reliant in water, based on the earlier wisdom.
This document summarizes a study on the physicochemical properties of soil affected by municipal solid waste (MSW) in a densely populated tropical region of Onitsha, Nigeria. Soil samples were collected from three locations - an uncontaminated control area 15 meters from two disposal sites, the crest formation at one site, and the basin formation at another. The samples were analyzed for properties like pH, organic matter, total nitrogen, heavy metals, and cation exchange capacity. Results showed increases in these parameters with depth. pH, nitrogen, zinc and iron were higher at the crest, while lead was higher at the basin. Aggregate stability decreased significantly at the basin compared to the control. Calculated values for tested parameters at

The document discusses the importance of proper management of natural resources like forests, wildlife, water, coal and petroleum. It states that as population, industrialization and urbanization increase, the demand for natural resources is also increasing while their availability is limited. Therefore, there needs to be judicious use of resources, long-term planning for use, and equal distribution of resources for present and future generations. It provides details on various methods of conserving forests, wildlife and water resources like afforestation, preventing deforestation, banning poaching, rainwater harvesting, and constructing dams with their advantages and disadvantages. It also notes that coal and petroleum are non-renewable resources that will last only 40-200 more years and
This document discusses a study that evaluated the impact of changing land use/land cover (LULC) on the hydrological processes in the Dal lake catchment in Kashmir Himalayas from 1992 to 2005. Satellite data and a hydrological model were used to analyze LULC changes over time, identify factors contributing to changes, and simulate the effects on runoff, erosion, and sedimentation. The results showed that decreased vegetation cover and increased impervious surfaces due to human activities led to greater runoff, erosion, and sediment discharge, disrupting the lake ecosystem.
This document discusses ecosystem services and their importance for human well-being. It defines ecosystem services as the benefits people obtain from ecosystems, including provisioning services like food production, regulating services like climate stabilization and water purification, supporting services like soil formation, and cultural services like spiritual and recreational benefits. The document notes that while human activities have improved lives, they have also weakened nature's ability to provide key services and increased pressures on ecosystems. It emphasizes that regulating and supporting services are undervalued and disturbances can be difficult to reverse, so continued lack of awareness will dramatically alter Earth's ecosystems.

Abstract: Solid waste disposal remains one of the major challenges of urbanization in developed and developing countries. The sanitary state of an area, particularly the sub-urban areas is influenced by waste handling practices by the residents and the measures put in place for safe waste collection and disposal. The objective of this study was to assess disposal mechanisms of solid waste among households in Kaptembwa location in Nakuru West Sub-County. The research adopted social inquiry design where a structured questionnaire was administered to household heads, oral interviews and focus group discussions were also conducted. The unit of analysis was the household selected in four estates. The study population was 400 households and a sample size of 200 households. The selection of the household units for data collection was based on simple random sampling. The data was analyzed using the Statistical Package for the Social Sciences (SPSS) computer software (version 17) and results presented by descriptive statistics (graphs and tables). Inferential statistics was also used to show the relationships between independent and dependent variables. The findings and recommendations of this study provide information not only to the Kaptembwa residents but also residents living in low income of urban and peri-urban areas to adopt best practices in solid waste management to improve environmental quality and enhance the health status by reducing the incidence of disease outbreaks. This can be achieved by the implementation of some key research recommendations which includes use of smart shopping to avoid the excess use of polythene bags, proper sorting and storage of waste, using improvised storage receptacles such as disposable cartons and dust bins as well as engaging the Community Based Organization (CBO) dealing with waste collection, transportation and disposal.

Magneto-transport properties of MnGeP2 and MnGeAs2 filmsIJERA Editor
MnGeAs2 and MnGeP2 thin films were deposited on GaAs and Si substrates. For these film samples, roomtemperature ferromagnetism was observed from magnetization and resistance measurements and verified from hysteresis in magnetization measurements. Hysteresis as well as anomalous behavior in Hall effect measurements was found in the deposited MnGeAs2 and MnGeP2 films, implying spin polarization of the mobile carriers in the films. The Hall resistance measurements above the ferromagnetic transition temperature showed that the carriers are n-type in MnGeAs2 and p-type in MnGeP2.

A Mobile-Cloud based Context-Aware and Interactive Framework for Diabetes Man...IJERA Editor
One of the biggest preoccupations of any healthcare provider is trying to eliminate the mistakes during treatment. Using Cloud computing permits to host all information in one place and make it accessible anywhere, anytime, and any channel, especially when it comes to the disease diabetes mellitus. Diabetes mellitus is a group of diseases characterized by an elevated blood glucose level (hyperglycemia) resulting from defects in insulin secretion, in insulin action, or both. It is, today, the most challenging syndrome in the world. In the latest survey, the world’s 65% of the population is suffering from either Type 1 or Type 2 diabetes mellitus. The patient’s blood glucose level is not the same 24x7 hours in most of the cases and take medication 24x7 hours is impossible. Cloud Computing is so the best solution to check in the patient’s blood glucose control and try to balance it, especially at remote areas where healthcare services aren't easily available.
A Study on self-Compacting Concrete Using Portland Slag Cement with Partial R...IJERA Editor
Concrete plays a vital role as a construction material in the world. In the present scenario, waste materials from various industries are added to the mix. Over 400 million tons of waste materials are being produced by various industries every year. Foundries successfully recycle and reuse the sand many times in a foundry. When the sand can no longer be reused in the foundry, it is removed from the foundry and is termed as Foundry sand. Foundry sand production is nearly 6 to 10 million tons annually. There is a possibility of substituting natural fine aggregate with waste foundry sand which offers technical, economic and environmental advantages which are of great use in the construction sector. The construction industry is now slowly becoming aware of the environmental issues and other sustainable development issues for cement and concrete industries. It is looking for the ways and means to develop building products, which will increase the life span and quality. This thesis presents an experimental investigation on strength aspects like compressive, split tensile and flexural strength of Self Compacting Concrete (SSC) containing an industrial waste foundry sand. It is used as fine aggregate in varying proportions, replacing the fine aggregate with foundry sand as percentages of 0%, 25%, 50%, 75%, 100%. For this green SCC, all SCC tests are performed as per EFNARC guidelines i.e. slump flow, L-box, V funnel and T50 tests are carried out.

Thermal comfort phenomenon is usually studied from thermal sensation perspectives on immediate environments from people’s perception; however, there is another key factor little if anything explored in this field which reinforces this acceptance/rejection physiological process: thermal preference. It is advisable, therefore, to analyze the thermal comfort from this approach that allows to explore it as a phenomenon of individual appreciation. This study is intended to estimate the local thermal comfort through the analysis of thermal preference using a sample of young adult residents of Pachuca city, in Hidalgo, México (semi-cold climate) during extreme thermal periods of a typical year: cold and warm. The data were processed using the “Average Interval of Thermal Sensation” (MIST)method, the results were evaluated applying Auliciems & Szokolaymathematical equations [1], as well as thermal sensation values previously estimated by the author. The results showed differences in terms of reference values of comparison; suggesting that Thermal Sensation (TS) analysis provides more consistent values than those obtained via the Thermal Preference (TP) analysis. Nonetheless, it allowed to infer that while the TS values implies a tolerable thermal range scenario, the TP analysis offers the idealization of thermal pleasing conditions.
CS Based Channel Estimation for OFDM Systems under Long Delay Channels Using ...IJERA Editor
Orthogonal frequency division multiplexing (OFDM) is a technique which are used in the next-generation wireless communication. Channel estimation in the OFDM technique is one of the big challenges, ever since high-resolution channel estimation can significantly improve the equalization at the receiver and consequently enhance the communication performances. Channel computation using superimposed pilot sequences is also a fully new area, idea for using superimposed pilot sequences has been proposed by various authors for different applications. In this paper, we are introduced a high accurate, low complexity compressive sensing (CS) based channel estimation namely Auxiliary information based Subspace Pursuit (ASP) in TFT-OFDM systems. ASP based channel estimation in TFT-OFDM system is based on two steps. First is, by exploiting the signal structure of recently proposed TDM-OFDM scheme, the supporting channel information is obtained. Second is, we propose the supporting information based subspace pursuit (SP) algorithm to use a very small amount of frequency domain pilots embedded in the OFDM block used for the exact channel estimation. Moreover, the obtained auxiliary channel information is adopted to reduce the complexity of the conventional SP algorithm. Simulation results demonstrate a important reduction of the number of pilots relative to least-squares channel estimation and supporting high-order modulations like 256 QAM.
Methods for assessment of a cooling tower plume sizeIJERA Editor
Currently, several methods exist for assessment of the total size of a cooling tower plume, which is created in the space above the evaporation cooling systems. Practically all the available methods, however, allow only qualitative assessment of this size. With the development of moisture recovery systems, there is a need to quantify the cited phenomenon, particularly to allow for assessment of MRE systems. The contribution for this reason discusses the compilation of a simple mathematical model on whose basis the cited quantification may be done. At the same time, it has also been proven that not even one of the methods applied to date can give correct results

This study carried out in BarombiKotto was aimed at assessing ecosystem services provided by Lake BarombiKotto and its riparian vegetation and to determine the level of awareness of this community to threats to degradation of water quality and riparian vegetation. Two hundred semi structured questionnaires were administered to the inhabitants of BarombiKotto village using the purposive sampling method. The Likert rating method was used to derive quantitative data that was further analysed using SPSS version 17. Results revealed that, respondents depended on the lake and vegetation for the provision of water for drinking, domestic purposes, irrigation, transport, recreational and cultural activities and also on forest benefits like wood for fuel, construction and medicinal plants. Significant associations were found between age group, level of education and respondentsawareness about the threats to water quality and sustainable practices. Agriculture, harvest of wood for construction, high fishing rates, increasing abundance of aquatic weeds were identified as major threats to Lake BarombiKotto and its surrounding vegetation. Water quality attributes like reduced transparency, lake depth, and other parameters such as aquatic weeds and fish stocks have changed in Lake BarombiKotto. The absence of conventional waste management facilities in BarombiKotto community and poor sanitary conditions of toilets could be responsible for the contamination of this lake and hence the high prevalence of typhoid, dysentery and other gastrointestinal infections among respondents.

Living on water and land: Challenges and opportunities for the development of...IEREK Press
Loreto, the largest Amazonian region in Peru, is home to more than 200,000 inhabitants that live in traditional
riverside rural communities adapted to an amphibious lifestyle, with houses that rise or float on the river in times of
flooding and perch on the dried riverbed in low water times. Nevertheless, these amphibious communities are not
exclusive to rural areas. Iquitos, the largest city of Loreto, is surrounded by alluvial plains, where more than 90,000
people live on the water and bring a rich social, cultural, and environmental vibrancy to the regions. However, poor
infrastructure conditions and limited resources in this communities affect the ecosystem and the population's health.
The objective of this qualitative study was to understand the physical, sociocultural, and environmental conditions
in which these amphibious communities live and identify the political, legal, and cultural barriers that prevent their
healthy urban development. Data collection was conducted through semi-structured interviews, surveys, and
observation of physical and environmental conditions. The results suggest conflicts in the formalization processes
of theses informal communities, from administrative and legal aspects to a limited definition of habitable territory.
We identified the benefits of the current urban-architectural conditions of these communities, whose housing
typologies, adapted to the seasonal change of the rivers, may provide a alternative model to adapt with resilience to
the impacts of climate change and sea level rise. We also identified challenges in sanitation, accessibility, public
space, and strengthe of community networks, as well as challenges in the response of the government whose
proposals for relocation of the amphibious communities have not fully considered these communities' economic,
social, and cultural values.

Abstract: Wetlands, all over the world, offer many livelihood support services to riparian communities and beyond
but are currently severely threatened with decimation. In Murang’a County, Kenya, wetlands are a key life
support system for many communities but their survival is currently uncertain due to extensive encroachment,
filling up, pollution and weak legislation. Our study aimed at investigating the impact of riparian community’s
livelihood strategies on wetlands conservation and restoration in Murang’a County, Kenya. Data was collected in
4-sub counties of the County using household’s survey questionnaires, key informant interviews, and focus group
discussion. A randomly selected sample of 404 respondents were recruited for the study. Data was analyzed using
SPSS software version 26.0. Results showed an encroachment rate into the wetlands by the riparian communities
of 60.4%. A highly significant and positive correlation was obtained between livelihood strategies and impacts on
wetlands ((r=0.184, p value =0.001). Members of the riparian communities were poorly informed about the roles of
wetlands, with 70% unaware of any wetland’s conservation efforts. A whopping 73.7% had not participated in any
wetland conservation effort. Hence, there is need for community sensitization and empowerment on wetlands wise
use as well as sustainable wetland utilization, conservation and management.
1. INTRODUCTION
1.1 Background of the Study
Globally, wetlands cover about 6% of the 5.7 million km2 of the Earth‟s surface and they support millions of livelihoods
as they act as „‟water banks‟‟ where water may be drawn and ground water replenished (Millennium Ecosystem
Assessment, 2005). Wetlands are as old as the Earth itself. By 20th century, the increased use of wetlands attracted the
attention of the world and a global meeting was held in Iran on 2nd February, 1971 to discuss wise use and conservation
of lands that were wet (wetlands), the meeting was named the Ramsar Convention and it has been the foundation of
wetlands conservation (Ramsar, 2017).
Wetlands have been places of interest since civilization as many towns and cities are built along the blue economy. They
have also served as transport corridors, source of wildlife, fish and seeds (Fisher, K. and Morling, P.). However, due to
population pressure, wetlands have been encroached into and converted to different agricultural land use and degraded
Davidson, C. (2014), observes that 87% of the world‟s wetlands have been lost since 1700 AD as a result of human
activities.
In the Kenyan economy, Lakes such as Lake Naivasha contributes 5.3 billion and over 30,000 people draw their
livelihoods from wetlands ecosystem but due to climate change, these lakes are contemporarily facing rising water levels
which in turn affects ...
Cultural Landscapes Preservation at the Interface Of Urban Planning and SprawlIEREK Press
From ancient times, the sea has played a key role in shaping and generating settlements and cities. Thehistoryof civilizations has been marked by the cultural development of human societiesalong coastlines.Accordingly,these territories are harbor of animportantcoastal heritage;that plays a pivotal rolein maintaining the link between the past and the future. In fact, while cities grow and their populations increase, their planning becomes a challenge for sustainable development.Through different forms and mechanisms, coastal sprawlis materialized, by the massive occupation of populations and industrial activities along coastlines. In this vein, coastlines endure many conflicts, which lead to the degradation of cultural and natural resources and may result in loss of cultural identity associated with the presence of cultural landscapes. The paper aims, to discuss planning approaches and challenges related to managing cultural and coastal landscapes, facing the impact of coastal sprawl. The paper is based on a landscape analysis; it interviews the urban, social, juridical and morphological frame.An understanding of urban sprawl throughthe lens of Annaba’s coastline is required for its implicationas a social support of the identity and the history of the city.The paper also examines how the coastalization affects the cultural heritage based on the monograph of one of the valuable French colonial constructions in Algeria. Lastly, the study demonstrates, some keyopportunities for advancing future adjustments, and coastal management approaches.For instance, new tools and more appropriate methodologies that combinethe preservation ofthe coastline and the preservationof the cultural heritage.

Implications of traditional beliefs and practices on natural resource conserv...bijceesjournal
The article presents an assessment of the implications of the use of traditional practices and belief systems on natural resource conservation, using a case of selected communities in Ghana (Fomena, Tepa, Tanoso, and Ejisu). The study adopted both qualitative and quantitative research approach to achieve the formulated objectives. A total of 208 (52 each) respondents were selected mainly by convenient and snowballing sampling techniques. Data were collected using both unstructured interview guides and questionnaires. The study revealed that taboos, totems, and customary practices are the major instruments used in the conservation and management of rivers in the study areas. However, it was realized that the traditional measures are challenged by the influence of western religion, education and modernity, increasing immigration resulting in a high number of foreigners, civilization and sometimes ignorance. The study recommends the traditional authorities, families as well as clergymen for people to appreciate the differences in African traditions and African religion should undertake that massive sensitization. Also, government or agencies (like the Environmental Protection Agency and the local assembly unit) responsible for taking care of the environment and its resources should incorporate the traditional measures in their policies and action plans toward natural or environmental resource conservation and management like water bodies.

Regional Resource Urbanism, Envisioning an Adaptive Transition for the Urbani...IEREK Press
Despite a strong tradition of harmony between the landscape and its settlements, Kathmandu's periphery now stands altered due to the contemporary challenges of modernisation. It has become the contested territory where rapid urbanisation and infrastructureprojects conflict with the valley's last remaining resources. i.e., fertile soil, floodplains, water sources, forests and agricultural land. The periphery is essential in preserving the remaining agricultural landscape, which is the mainstay of the numerous traditional communities of Kathmandu. Both the occupants and the productive landscape are threatened due to haphazard urbanisation and future mobility projects, resulting in speculative and uncontrolled sprawl. A detailed investigation was conducted on a site 15km south of Kathmandu to address the city's landscape challenges. The chosen investigation frame presented the suitable conditions to study and test strategies posed by the research objectives. The research utilises landscape urbanism and cartography to reveal the landscape's latent capacities, identify the spatial qualities, stakeholders and typologies involved in the production and consumption of resources. The study identifies existing resource flows and their ability to generate future scenarios. Systematic design strategies were applied in resource recovery projects by optimising enterprising capacity building within communities after the earthquake. The research recognises the merit in existing practices, community networks, the ongoing post-earthquake rebuilding efforts in offering an alternative design strategy in which landscape becomes the carrying structure for the sustainable reorganisation of Kathmandu's periphery
HOW THE LULA GOVERNMENT CAN PROMOTE ENVIRONMENTAL SUSTAINABILITY IN THE AMAZO...Faga1939
This article aims to present proposals that enable the Lula government to promote the environmental and ecological sustainability of the Amazon. There are several environmental problems that affect the Amazon. The Amazon Forest is threatened with destruction due to deforestation and fires resulting from the expansion of agricultural and logging activities, mineral exploration that has been leaving a legacy of poverty and serious socio-environmental impacts, the implementation of highways that have been causing great environmental impacts in the Amazon and the hydroelectric plants whose planned reservoirs are causing so many negative impacts to the environment that their construction should not have taken place. Of all the existing environmental problems in the Amazon, the main one concerns deforestation and fires which result in the emission of CO2 into the atmosphere. In order to avoid the devastation of the Amazon Forest and ensure that the natural resources existing in the Amazon are used rationally for the benefit of the vast majority of the population living there and for the economic and social progress of Brazil, as well as the fight against global warming, it is essential that there be effective environmental management based on a network structure that integrates the actions of all public and private agencies operating in the Amazon.

This document summarizes gaps in the literature on managing resource development and its environmental legacies in northern Canada. It identifies two main gaps: 1) There is limited research on meaningfully incorporating Indigenous participation and knowledge into assessing and managing large-scale non-renewable resource projects, beyond just renewable resources. 2) There are few studies examining the long-term environmental impacts of development, ongoing effects on communities, and local involvement in remediation. More work is needed on these topics to promote socially just and sustainable development in the North.

The document summarizes a study on the impacts of land use on water quality and flow in the Andranomena River basin in Madagascar. The study found that:
1) A sub-watershed with mixed hillside cultivation ("savoka" agriculture) exported significantly higher amounts of total suspended solids, total dissolved nitrogen, and had a higher average stream temperature than an undisturbed forested sub-watershed.
2) The cultivated sub-watershed experienced greater "flashiness" during rainfall events, with a higher ratio of surface runoff to rainfall compared to the forested sub-watershed.
3) Savoka agriculture was found to cause increased flooding, soil nitrogen depletion,
Biophysical Characteristics and the Anthropogenic Activities in San Roque Riv...YogeshIJTSRD
River provides essential various ecosystem goods and services that are essential for living organisms’ survival. As such, its quality must be maintained to ensure the healthy condition of the environment as well as the safety of the community. The study aimed to assess the biophysical characteristics and the anthropogenic activities in San Roque River, Northern Samar. It employed descriptive research combined with laboratory analysis and SPSS was employed to treat and analyze the data.The study revealed that the physico chemical characteristics of the water in San Roque River in terms of temperature, pH, TSS, TDS, and turbidity were within the DENR standards. However, the water of the river was highly contaminated with total coli forms and fecal coli forms. Likewise, the salinity was beyond from the standard that made the water of the river salty. T test revealed that the characteristics of water during high and low tides showed no significant differences. On the contrary. It has shown significant difference on water parameters in terms of temperature, pH, TSS, TDS, BOD, and DO between high tide and the standards. Likewise, pH, TSS, BOD, and DO have shown significant difference on low tide with the standards. It also revealed that there were anthropogenic activities and practices of the community living along the river that directly affect the water quality and condition of the river. Moreover, this also concludes that there were no significant relationships on the characteristics of the water and the anthropogenic activities. Lastly, the San Roque River was classified as Class D river at the time of the conduct of the study. This concludes that the river needed rehabilitation so that the potential uses of the river would be maximized which would redound to better benefits of the community. Elvin L. Jarito | Gerald T.

Lake Chad Casestudy
Lake Chad is one of Africa’s fresh water bodies. This water resource is shared by Chad,Nigeria,Niger and Cameroon. This important ecosystem has been experiencing degradation because of natural factors and human activities. This research focuses on the role of human factors in the degradation and the management plans that have been put in place to manage the resource.The unfortunate situation at the lake has been called an ecological catastrophe by the Food and Agricultural Organization, FAO. Some of the human factors that have contributed towards the degradation include damming and irrigation. These two human activities have contributed to the shrinkage of the lake. The growing number of irrigation projects have diverted water sources from the lake, hence the massive degradation. A series of dams constructed across rivers in Nigeria and Chad have also affected the lake because they have interruption the natural flow of water that originally drained in Lake Chad (Kolawole,Omali&Daniel, 2012).
Livestock staging, and overgrazing, has been witnessed in the surrounding areas. There is a lot of competition for greener pastures in the area. It is this competition for resources from the surrounding herders (e.g. to keep them fed and healthy) and current occupants struggling to keep their livelihood alive, that has made the lake vulnerable to further degradation. Human factors have indirectly contributed to drastic climatic changes that have resulted in droughts and high rates of evaporation at the lake (Kolawole,Omali&Daniel, 2012).
The increasing human population has put pressure on this natural resource. The growing population has contributed to unsustainable exploitation and pollution of the Lake. Over 30 million people live within the water catchment area around lake Chad (Kolawole,Omali&Daniel, 2012). With this size population, the water resource is being thwarted into extinction if conservation measures are not implemented. The population has also resorted to intensive fishing in the lake for survival. This overfishing is a major threat to the ecological biodiversity within Lake Chad itself Kolawole,Omali&Daniel, 2012).
Ecological Principles Ignored In The Degradation
Disturbance Principle
According to the disturbance ecological principle, the extent and type of disturbance, determines the characteristics of the ecosystem. In the case of lake Chad, human activities were carried out in total disregard of the potential effects they had on the ecosystem. The population around the lake, exploited resources and disturbed the water balance in the area, therefore furthering the rate of the lake’s deterioration.
The landscape ecological principle was also ignored. The human activitie.
Social changes in coastal community affected by the conversion of environment...Alexander Decker
This document summarizes a research study on social changes in a coastal community affected by the conversion of environmental resources from mangrove forests to aquaculture. The study used qualitative methods to examine how development led to changes in work patterns and social relationships. Key findings included:
1) Development led to changing work patterns from fishing and woodcutting to jobs in aquaculture.
2) Social differentiation and commercialization of the economy weakened ties between community members.
3) Relationships became based more on personal interests than the local community.
4) Belief in supernatural aspects declined as rationality increased in ways of thinking.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

ABSTRACT
This article´s objective is to study the construction techniques of the riverside dwellers in the Amazon rainforest.
The studied communities are located in the banks of the Solimões River, and suffer with the constant floods and
physical phenomena related to the region environment. An ecosystem of thunderous natural forces, which makes
it harder the importation of approaches from other regions as alternatives to the Amazon rainforest. As a method
of research and understanding of the problematics, an assessment of the riverside communities in the city of
Manacapuru and in two rural communities was carried out, surveying the cultural, social, and environmental
characteristics of each community, and surveying the local constructive characteristics, materials and vernacular
techniques. In the conclusion, we observed that: the relevance of a joint action to understand the wood and the
housing durability, expanding the life cycle of the river buildings and reducing the impact on the rainforest.
Regarding thermic comfort, it is important to redeem the bioclimatic techniques of crossed ventilation and to
highlight the relevancy of sustainable techniques that work with local materials, such as natural fibers.
Keywords–culture, environment, house, riparian, riverside population.
I. INTRODUCTION
The main problems highlighted by Bertha
Becker [1] researcher that studied the Amazon
region confirm that the phenomenon of nature, the
floods and river often brings with it challenges for
the riverbank populations. These geographic factors
are amplified by the lack of basic sanitation and
potable water, difficulty to access the healthcare
service and the great distances to the urban centers.
Themajorityof houses aren’t adapted to the
hydrological cycles that occur annually, during the
flood period. The riverine population is subjected to
the contamination of the water by solid wastes, fungi
and bacteria and animals.Cohen et al [2] point out
the importance of allying the conditions for a
“healthy habitat to the strategy of primary
environmental care”. These factors determine “the
results of a gradual process to improve quality of
life”. According to the authors, “the habitat is the
space that surrounds the physical element, the
dwelling. The environmental quality in this built
space, and in its surroundings”, leads to quality of
life.
The Amazon region is rich in geographical
elements and natural resources, yet it lacks
expansionist actions of religious, social and cultural
groups, as well as investments in research. These
actions promote the interaction between researchers
and communities.Thus, the exchange of knowledge
and experiences favors the social inclusion and
improves quality of life. There is a gap related to the
dwelling due to the buildings’ low durability in the
area, lack of comfort and of basic sanitation, with
waste thrown in the rivers, among others. It is
possible to stress out the lack of technical formation
associated to the wood, generating the lack of
housing quality, as observed by Schneider et al [3].
A second point is the lack of valorization of the
goods associated to the local culture and to the
intrinsic nature of the humid tropic regions.The
present study was carried out in two distinct
Manacapuru zones, in the Amazon State, localized
in average at 68 km in straight line from Manaus,
and the other at 35 km on the right bank of the
Solimões River, with latitude and longitude of
3°17’29,44”S and 60°37’54.62”O.
The first visit was held in conjunction with
the Department of Civil Defense of the State of
Amazonas, at the Correnteza neighborhood, in the
city’s urban center, where there are informal
occupations. According to the 2010 City Master
Plan, the Department of Civil Defense informs that
families should be relocated from the risk areas. This
Year, three neighborhoods were at risk: São
Francisco with 397 families, Liberdade with 377,
and the Correnteza neighborhood with 330 families.

The second visit was in the countryside, in
a scenario of densification opposite to the one found
in urban centers. Two communities were located in
Costa Canabuoca, at the right edge of Solimões
River, geographic region that houses approximately
eight rural communities.At this location, two
communities can be highlighted: Canabuoca 1 and 2,
which are characterized by their landscapes of a
continuous length of floodplain, thus subjected to the
process of water-level fluctuation. This oscillation
between the terrestrial and aquatic phases [4]
promotes environmental changes, allowing different
activities in order to optimize the use of available
resources in different phases of the year. Lakes,
beaches, flood plain and forests are components of
this landscape.
II. METHOD
From an analytical view over the
abovementioned aspect of geographical formation,
we aim to understand the territory through the
concept of cultural environment [5].Formed by a set
of physical and cultural manifestations, this
environment reflects the sum of intangible assets,
such as traditional practices of, past and present
communities, materialized by means of buildings,
objects and tools, among others.The culture of
dwellers riverside, like many other societies of the
national territory, is the result of a long-term
occupation process of the amazon rainforest by a
diversity of cultural identities[6].Therefore, the
multidisciplinary involvement of different areas of
knowledge, especially the traditional practices
transmitted through the participation of social actors
and representatives of those communities,
independently of its location zone, urban or rural, is
considered of paramount importance. Given this
premise, the methodological challenge is to give
voice to the local community. Considering
ofchallenge, field activities were carried out, as well
as surveys of the edified material assets, non-
structured interviews, photographs and
measurements therein.
Thus being, from a field registration
system, tangible and intangible cultural assets, which
are still linked to the territory, were surveyed.
Territorial aspects were surveyed during the
assessment, some of them being:
1. the human relationship with the landscape
transformation; social-cultural aspects; lifestyle
survey; the traditional knowledge focused on
housing construction; the use and management
of local raw material;
2. Technical data;
3. Housing dimension and temperature
measurement.
Three communities were visited throughout
the field research carried out in April 2016.
Meetings were held in each community, totalizing
11 interviews with the residents of the region.The
interviewees were representatives of each
community. Please note that only their first name is
presented in this article, in order to preserve the
residents’ privacy. The interview transcription and
the technical data compilation were performed
during the post-field research period. The field
measurements were performed with measuring tape
and laser thermometer. Therefore, the housing
building technique was represented through digital
media, in drawings with tools such as AutoCad 3D
and SketchUp. After doing so, the critical analysis of
the aforementioned aspects was added herein.
III. THEORETICAL REFERENCE
The first wave of migrants arrived in the
region in search of work, during the so-called rubber
cycles, between the middle of the nineteenth century
and the mid-twentieth. In the second cycle, there was
an increase in the population quotas that sought after
the promise of wealth[7]. As said by Wille Bolle, in
Amazon, there is a search for diversity of natural
resources, ever since the colonization until the
present days [8]. This idea of extractive exploration
is frequent in the history of Brazil’s occupation,
which indicates an approximation between greed and
domination, since its colonization, recurrently in
Amazon[6].The decay of these systems of migration
and immigration, due to exploratory factors during
the history of the Amazon occupation ended by
making relative the absence of urban dynamism. The
several and diverse outbreaks of this migration
process did not promote the local development[9].
Therefore, the Riverside communities are not natural
from the Amazon; along with the environmental
conditions, a traditional identity was built, inhabiting
the riverbanks and expressing itself not only as an
integration with nature, but also as a social adaption
to historic conditions.
The riverside dwellers have a large
knowledge of the territory, its riches and natural
potential, and they know the importance of its
preservation. For this reason, the way he organizes
his life does not devastate the environment, he
knows that he will need nature for his survival. As
described by researcher of the geography area, the
Amazon riverbank population developed an adaptive
process with local biodiversity, due to the strong
relation of dependence with the environment that
culminates in a combination of the integrated use of
the physical space, along with the multiple uses of
the available resources [10]. It is no different when it
comes to housing construction; the knowledge about
the raw material management, and the building
procedures, is passed from generation to
generation.Their way of life carries remainders of
the past, present, and “future” expressing several

temporalities regarding distant times, to the
indigenous legacy, to the colonialism and to
migration processes that take place to this day. Ana
Carolina Brugnera in your master’s dissertation
concludes that it is possible to identify that the origin
of this population is not constituted only out of the
traditional Amazon populations identifying peculiar
nuances of the way of living that are reflected in the
architecture with its direct link with the landscape in
which they are inserted. Their physical aspects, such
as hydrological, geological, geographic aspects,
added to their history and culture. It can be noted
that during the process of occupation the exchange
of knowledge between different actors in society
occurred [6].
IV. DISCUSSIONS AND RESULTS
In order, to analyze the cultural, the
environmental characteristics, and the construction
techniques, a review on the literature was carried
out, complementing the field studies and the visits of
the researches to the environment, the observational
visits and the interviews.
IV.I. Environment and culture:
On a field trip, in one of the Costa do
Canabuoca communities, the Canabuoca 3
community was visited, and an interview was carried
out with its representative, Mr. Raimundo. There is a
variety of communities along Solimões’ River
channel. The interviewee states that just within
Costa do Canabuoca-Manacapuru/AM, there are 8:
Pesqueiro, Marrecão, Canabuoca 1, Canabuoca 2,
Canabuoca 3, Vila do Jacaré, Nova Canaã and São
Geraldo. The last one being next to the border with
Anamã city (see figure 1). Mr. Raimundo, born and
raised within the community, is Napoleão’s son, as
he reports in the interview: “I was born and raised
here and I worked during my entire youth…. When I
was 30 years old, I moved to Manacapuru. In the
city, I built my house and raised my children, but I
myself was not able to adapt, so I decided to go back
to the countryside. My father lived in this little house
next to mine on his own; God and him. It took me a
while to get used to the countryside again, to crop, to
fishing… Then, I slowly started to bring my family
back. There were still some family members that
stayed in Manacapuru. Nowadays, I am 59 years old
and I am healthy enough to work, thank God”.
Just as the Family of Raimundo and
Napoleão, whose grandfather, father, son,
grandchildren and great-grand children live in the
area, according to the community representative,
there are other 130 families registered in this place.
The daily life of these families is directly linked to
the nature of the forest, to the water cycle and to the
management of their natural resources that guarantee
the subsistence of these people that live there. There
is time to fish, to produce the flour, time to harvest,
of the guava and açaí.

communities of Costa do Canabuoca, quoted by
Raimundo. Source: Adapted by Ana Carolina
Brugnera from Google Earth, April 2016.
In the community of floating houses Rosa
Mística, located near the city of Manacapuru, the
strength of this culture can be highlighted.An eight-
year-old boy navigates along the Solimões River on
top of a three-meter-long canoe. He speeds up the
stern-drive engine, and goes towards the dry land,
approaching Canabuoca’s Coast, where his
houseboat, fixed upon the açacu logs, is
located.When he is almost reaching his destination,
he turns off the engine, retracts it and within
seconds, he grabs the paddles. Aided by the ripples,
he rows towards his home. Amazon pulsates; men
live there in harmony with nature. His father is Mr.
Renato, a fisherman, who decided to live “on the
water” due to his profession. As he says “the closer
to the river, the better”At the time of moving, some
friends from the local community helped him build
his house. They gathered the floating açacu logs and
raised the basis over the water, the structure of the
floor (wood), the mainstay, poles and roof structure.
Under the cover, the floor was built, the walls gasket
and the inner divisions, all madeout of wood. It is a
job that demands a lot of effort. As Mr. Renato says:
“as you can see here, it is a house made of wood that
floats over the water. It moves wherever you want it
to. It adapts to nature and to the river.”
The profiles of this Riverside population
described above are a constituting part of the long-
term process of occupation of the Amazon territory,
according to interview with the secretary of
environment of Manacapuru, “they are called
Riverside populations because they originated by the
river side, and the occupation starts on the river
side.”The occupations that characterizes the rural
areas had gone through modifications, in the
territorial space, small urban nuclei were created,
classified today as Amazonian municipalities and
their districts, where the population that lived far
from public services, like schools, health and urban
infrastructure, come back to the urban centers

searching better quality of life. This rural exodus
causes, many times, social problems. Cities that
receive a great amount of migrants, that many times
are not prepared to such phenomenon. The Jobs are
not sufficient and many migrants start working in the
informal Market and come live in housings with no
good conditions, like “favelas” and “human
beehives”.
In the urban areas, the agglomeration of
people creates social vulnerability and risky
conditions to the population that lives there. These
conditions are intensified by physical factors, like
flood areas, earth sliding and anthropic factors,
resulting from human activities, like construction of
housing on unstable ground, leading to informal
occupations, using rudimentary techniques.The
neighborhood of Correnteza in Manacapuru is an
example of this phenomenon that was identified
during the visit. The riverside people brought their
customs from the rural zone and they used their
customs in the city, creating hygiene and security
problems, since they were placed at risk areas. The
families that lived many kilometers away from each
other now are living very close, within a five to ten
meters’ range.
In Manacapuru, these migrants are in
peripheral regions, by informal occupations, in
places like the Correnteza, Liberdade, São Francisco
and Biribiri neighborhoods. Differently from the city
center (downtown), which is located in higher lands,
these neighborhoods are in areas that are easily
flooded. Manacapuru is located between different
sources of water, with the main access through the
channel of Solimões River, which is surrounded by
lakes, like the Miriti Lake and further on the
Manacapuru Lake and the Cabaliana one. In the
Waters period, the floods cover these lower land
neighborhoods.Houses are abandoned by their
residents, wooden walkways are built for the
mobility of families, one raised floor is built inside
the buildings and houses, to escape the waters.
Amidst the problems brought about by the flood,
which occurs every year, it is clear the lack of
planning for the expansion of the city and its
infrastructure.
The population that escaped from the rural
hinterland finds new problems, now due to the
untidy occupation in urban centers. The issue is no
longer regarding neglecting public services, but the
distance up to these services as a lack of urban
infrastructure, mainly those related to a lacking
public health and lack of basic sanitation.

In the city’s periphery, in the Correnteza
neighborhood, there are houses in situation of
structural collapse, in special, in areas where the
wood foundation the large majority of time remain
in a flooded area. In addition to the problems
mentioned, many riverside dwellers throw the
sewage under the house, aggravating the problems of
foundation. Due to the Strong movement of the
floods, there were houses where the pillars were not
aligned, getting distant from the floor structure in
wood. The population requires that the governors
and the civil defense find ways to move these
dwellers somewhere else. The two Fig. 2 and 3 show
the houses of Street of Afonso Pena, considering the
situation of structural risk.
IV.II. Constructive techniques:
The visited houses in the rural
communities, differently to urban zones, find a
constructive richness in terms of finishing, with
gables and guardrail, each house with one color and
details that represent its dweller’s identity.As one
can observe in Fig.4 and 5. Fig.4 shows the floating
log houses and Fig.5 shows stilt house, built on
lowland areas.

In Costa Canabuoca, the communities take
the raw material out of the Amazon forest and
during the rains (June-August), the water level rises
and facilitates the access to areas on land, where
there are durable woods, for instance the
Maçaranduba – Manilkara. Another fact is that in
this region there are no sawmills nearby, and thus
the own community enters the forest and through
management they determine which trees will be cut.
Amid the forest, they collect the wood and craft
pieces for construction. Note that this is not
commercial exploitation, as they extract the wood
for their own housing, public and community
buildings only.Mr. Napoleão lives in the Canabuoca
coast, and the distance from his house to the
permanent course of the Solimões River is short.
During the floods, this distance is closed. During this
time, the house remains over the stilt under the river.
In his country house, there are three buildings
drawing the attention, since they date back to
different times: a small wooden house, very rustic
with no balcony, gables or any ornamentations, that
belonged to his grandfather. The second, somewhat
larger, and somewhat taller, belonged to his father.
The third building, which we visited, the family’s
current residence, is taller in relation to the old
constructions, well structured, with a balcony at the
front portion of the house, directed towards the river.
These houses display how the constructing technique
has evolved throughout the years.
As it is identifiable in field researches, the
housing in Canabuoca coast harmonizes itself not
only with the oscillation of the water level, but also
with the transformation of the landscape resulting
from the forces of nature, in different periods of the
year. It is identifiable in the location that the
riverside people of this region have been elevating
each time more their houses due to the climate
changes occurred during the last decades, generating
a larger volume of water in the river floods in
Amazon. Another factor that can be held responsible
for the difference in the heights of the stilt of the
three houses above analyzed is the accumulation of
sediments left in the river channels due to the waters
running down the Andes [10]. Therefore, these
landscapes are extremely dynamic, according to Mr.
Bernardino:“...in Canabuoca Coast, the floods
happen every year and they are violent, destroying
everything... Still, people start all over again every
year, since everything is ended here [...]. Down the
river, a house fell due to the big waves of the ships;
here, nothing happened since the ship passes by the
other side of the river”.
The houses of the riverside people have few
internal divisions in general that divide rooms, living
room, and kitchen. The buildings in general have
wooden structures and gaskets, their cover today is
predominantly out of aluminum, due to the easy
access to constructing elements manufactured
especially on regions close to urban centers. In the
more isolated regions, there are buildings covered
with straw roofs, a material used in the beginning,
for example as a hut under construction registered in
the community of Canabuoca 1, see Fig.6.
Figure 6 - Hut in construction with roof of straw,
registered in the community of Canabuoca 1. April

House building is a men’s work, and a
collective work. The riverside people build their
houses or buildings like a church with the aid of
their children, friends and neighbors. In a field trip,
we had the experience to witness a family building
their house on high pillars, and children reproducing
the knowledge through child games, working with
what was left form the wooden construction, small
houses in the inferior gap between houses,
miniatures of high pillars, as shown on Fig. 7.

The foundation, of the building in stilt
house wood in general is made with the pillar
directly on the soil. Regarding the structure of the
construction, stilt house or floating over water, it
presents the same components assembled in
sequence: the pillars and wooden by compression,
that are the supporting structures; once the vertical
structures are fixed, the longitudinal and transversal
poles are the support for the floor and roof wooden
pieces, stabilizing the building structure.With the
main structure of the building done, the riverside
people place its cover. This may be of straw,
asbestos, zinc, fibro-cement or aluminum, allowing
them to work, the floor, gaskets and placing window
frames in the shadow cast.As Mr. Napoleão says:
“Here, the roof is done first, and then we work on
the floor coating, so that it does not receive the heat
of the sun.In such case, the floor covering spikes up,
due to the insufficient drying period.”The treatment
that is applied to the wood in this region is
rudimentary, distinct from the professional industries
of wood commercialization in Brazil, where the
wood is considered dry with a humidity rate of 12%
to 15%. Mr. Bernardino reports that in Riverside
buildings, the drying time is practically null. The
wood is used green with a 33% humidity rate, the
same humidity rate of wood when it is removed
from the forest. This fact causes several problems in
the building, among them the rotting and the
retraction. He notes that to prevent the cracks, "[he]
nails the wood boards as close as possible to one
another". One of the cultural beliefs of this
population is that when the wood is removed under
the moonlight, it will be spoiled. They emphasize
that woods such as Itaúba (MezilaurusItaúba), Louro
(Bastardiopsisdensiflora), Andiroba and
Maçaranduba are strong, and even though they are
still wet, they are resistant to pests and bugs.
The field work indicated that the distance
from the floors in the stilt houses to the environment
is of about 1,5 meters, because the Riverside people
have been raising their houses each time more, due
to the influent climatic changes occurred over the
last decades that directly interfered in the volume of
water and in the floods of the rivers of the Amazon
region. Another factor that is less influent, but also
acting upon the housing, is the accrued sediments
(sand) left in the rivers’ channels due to the Waters
coming down (ebb tide); therefore, these landscapes
are extremely dynamic [10].
The sandy soil is a soil with little cohesion,
that is, its grains are easily separable from one
another when dried and with a temporary cohesion
when humid. This fact accelerates the problems of
global stability of the buildings in stilt houses, once
their foundations is superficial, and the houses are
subjected to the movement that happens in the soil
due to the annual floods. Another point taken during
the field trip was the lack of stability of the buildings
that in general do not have cross bracing. These two
factors result in the observed problems like the
houses with inclined pillars, or that lack any support
to the beam whatsoever, see Fig.8.

level of water. Source: Picture by Ana Carolina
Brugnera.
Current researches highlight the importance
of the Housing Project in considering sustainable
parameters for the comfort of the residents, aiming
at a more durable building, so that to increase the
life time of a building, among other factors
integrating bioclimatic concepts, like cross
ventilation [11].As of the durability of the Riverside
houses, some points observed therein can be
highlighted, such as: the wooden pillars in general
are directly dug in the soil, which speeds up the
rotting process over the course of time. In this case,
some communities cut the pillars and elevate the
building, in new wooden pillars. In general, the wet
areas, like the bathroom and the kitchen sink are
located outside the houses.
Another related point, which directly
affects the durability of the riverside housing, is the
fact that most houses present small eaves. It is
known that the farther the wood is from the water,
the longer the building may last. Another important
aspect is the shape and composition of the gasket.In
Manacapuru, the majorityof the houses present
wooden boards nailed upwards. During the floods
and the period of rains, these boards get rotten in
their foundation, demanding the removal of the
whole board for maintenance.These factors
accelerate the wooden houses degrading process and
directly impact the forest cycle of life.
For some decades, when in this Amazon
region, the access to industrialized constructive
elements was restricted, the cover of the houses was
made of straw, material that provided them with a
fresher environment to the building’s interior. Over
the last years, new elements made it to the region,
the riverside population adopted the aluminum and
zinc to build its cover. According to Oliveira Junior
[12] this roof tile when curled fits in a small boat
called fast boat for local transportation, and so, this
element easily arrives at the more isolated locations.

However, according to measurements done in site,
the aluminum roof provides a big thermal discomfort
inside the buildings, at several times with an internal
temperature being higher than the external. For
instance, according to readings performed by our
thermometers in site, at Mr. Napoleão’s residence,
the temperature in the internal environment
registered 34°C and on the aluminum roof it was
50°C, while the external temperature in the
environment was 29°C.Mr. Napoleão’s house
presented a porch turned towards the River and
eaves a little bit larger than those normally found in
the region. It can be noted that the higher
temperatures directly affect the quality of life of
those who live there.
The majority of the houses in the region
needs to go through a process of recovery, on an
average of a 15-year basis. This is considered a very
short period for a housing cycle of life. This is a
distinct reality from that in the Brazilian Southeast
cities, where housing is designed to last more than
one generation or century. At the same time, this
reality is impacting on the life of the riverside
people, since many times due to the nature
phenomena, they need to rebuild a new house.As the
study of Association “Wood for Good” points out,
the durability of a wooden building when well
designed may compete with brick, concrete and steel
buildings [13].
V. FINAL CONSIDERATIONS
The researchdemonstrates the importance
of field trips and the participation of the Riverside
community for the understanding of the cultural
characteristics and the problems the population
copes with[14].The importance of the involvement
of different researches, with the communities, with
the valorization of the concept of housing and an
adequate knowledge of the architecture design.
Therefore, elements that enhance comfort, building
durability and technical development of the wood
are sought, instructing community officials to
understand how to work with the wood in the
building.We observed the importance of a joint
action, for the understanding of the wood and with
an adequate and durable housing design, thus
extending the cycle of life of the Riverside
buildings, and decreasing the impact on the
florets.As an example, we can highlight a few points
to a longer durability of the building: a concrete
foundation; pillars with variable heights, sensible to
the water level, use of porches and larger eaves,
board gaskets nailed upwards. To amplify the global
stability of the Riverside people, they should recover
the elements of cross bracing that over the course of
time have been lost.
In thermal comfort, the importance of
tracing back the bioclimatic techniques with cross
ventilation and chimney effect to minimize the heat
near the aluminum tile, or working with a double-
aired roof. It is highlighted the relevance of
techniques that work with the development of local
materials, such as natural fibers for the improvement
of the housing, so it is not needed to import
industrialized materials that are not adequate to the
weather.The importance of joint actions among the
universities, governments, communities and
associations that enable the implementation of
technical courses on wood and industries in the
region, with the production of wooden components,
seeking to determine the durability and the quality
needed to tend to the riverside people’s needs. As an
example, we highlight the laminated glued wood,
laser cut wood, closing panel factories, with
humidity control.
