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

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 ...
Geothermal well Site Characteristics from Climate Resilient Technologies in N...QUESTJOURNAL
ABSTRACT: Geothermal energy is regarded as a clean energy source. This assertion has a degree of truth subject to technological interventions applied in its extraction. This paper focuses on quality of vegetation, soils and water points at well sites. The concentrations of trace elements at the well sites is mainly determined by adequacy of technological interventions. Geothermal energy is classified as renewable source and climate changeresilient. However, ineffective interventions andreservoir characteristics could result in undesired effluents to the surrounding rendering it unsustainable. More so, the resource is located in fragile ecosystems pivotal in climate change resilience. Simple random sampling of 81 wells was done. Samples were collected and analyzed in the laboratory. The results indicated that contamination of the vegetation, soils and water was evident. Boron concentrations in the soils for instance resulted in a sigma value of 5.99 and p- value of 0.00. This meant its concentration was significantly higher as compared to recommended standards set by Kenya’s environmental Authority. Therefore, undesirable environmental impacts were a reality in geothermal production and hence could jeopardize efforts for building climate resilience.The choice of technology thus has a bearing on climate resilience for a geothermal facility especially those located in fragile ecological set ups.

Analysis of Spatial and Temporal Changes in Land Use in Lushan City over the ...PriyankaKilaniya
In the past two decades, with rapid urbanization and economic development, the land use structure of Lushan City has undergone significant changes, posing challenges to ecological security and food supply. It is necessary to explore its spatiotemporal dynamics and driving factors to optimize land management. This study is based on land use data from 2000 to 2020 and uses GIS to analyze the spatiotemporal changes and transfer status of land use types. The main method is to use the land use transfer matrix and the single land use dynamic degree to study the land use change and its driving forces. The results indicate that the land use change in Lushan City is characterized by the conversion of arable land into construction land and the conversion of wetlands into water bodies. The area of arable land and wetlands has significantly decreased, while construction land and water bodies continue to increase. From the perspective of spatial distribution, the increase in construction land is concentrated in the central part of Lushan City. The driving factors of land use change in the city include the policy of returning farmland to forests and lakes, rapid economic development, changes in population, and the continuous promotion of the tourism industry.

Land cover transition and fragmentation of River Ogba catchment in Benin City...Glory Enaruvbe
This study examined variation in the intensity of land cover transition and the pattern of habitat fragmentation
of River Ogba catchment. Landsat images of 1988, 2002 and 2016 were classified into five categories: low
density urban, high density urban, mixed vegetation, agriculture and dense forest using maximum likelihood
classifier. Intensity analysis approach and landscape metrics were used to analyze the changes and fragmentation
of the land cover. Number of patches, largest patch Index, area-weighted shape index and Euclidean nearest
neighbour were computed. The results show that although mixed vegetation accounted for the largest land cover
category in 1988 and 2002, low density urban dominated the study area in 2016. Intensity analysis of land cover
change in the study area indicates a rising trend. The urban fringe is observed to be highly dynamic zone and this
is primarily driven by changes in agriculture, low density urban and mixed vegetation. The implications of rapid
land cover transition and fragmentation in River Ogba catchment, and especially in the urban fringe, include
threat to biodiversity, food supply and deteriorating environmental conditions. This study provides necessary
insights for developing sustainable strategies for urban landscape planning, administration and governance.
A REVIEW ARTICLE ON IMPACT OF URBANIZATION ON HYDROLOGICAL PARAMETERS IAEME Publication
As longas human being continues to exists,urbanization continues. Urbanizationhasa direct effect on environment which in turn effects the variations in hydrology. It may results from changes inthe land use pattern to built-up areas resulting in runoff which ultimately leads to flood. Most of the studies revealed thatland use pattern has drastically changed in whichthe builtup area increases year after year.The land use land cover changes can be identified using GIS. Many researchers have found that urbanization has an impact on hydrological parameters such as runoff volume, discharge in drains, infiltration, interception, evapotranspiration etc. An attempt has been made to consolidate the review of literature related to impact of urbanization on hydrological parameters.
A Major Irrigation Project (Accelerated Mahaweli Programme) and the Chronic K...Agriculture Journal IJOEAR
Abstract— The Mahaweli River is the longest river in Sri Lanka. In 1978, the government of Sri Lanka launched the Accelerated Mahaweli Development Programme, under the purview of Mahaweli Authority of Sri Lanka, the largest irrigation program in the country. It is a multi-purpose development scheme designed for the generation of hydroelectricity, irrigation, and water for domestic consumption. Since the mid-1990s, a major, non-infectious epidemic of chronic kidney disease of multifactorial origin (CKDmfo) has been reported in Sri Lanka for which no cause has been identified. This disease predominantly affects dry zonal, agricultural regions, particularly the North Central Province (NCP). During the past two decades, thousands of people have died due to this disease. This article assesses whether there is a relationship between this environmental impact from this major irrigation project and the deadly disease of CKDmfo. Water in the Mahaweli River is known to be polluted with various compounds, including phosphates coming from the excessive use of fertiliser in the hill country. However, the levels of phosphate in the Mahaweli River and in the NCP reservoirs are less than 0.15 mg/L. Such levels can cause ecological harm but are not a threat to human health nor causes renal failure. In addition, there are large regions outside the Mahaweli-fed localities where people are affected with CKDmfo. Thus, it is unlikely that water from the Mahaweli River itself is directly related to the occurrence of CKDmfo, but its harmful environmental impact is noticeable. Nevertheless, excess phosphates can cause algae blooms and cyanobacterial growth in water bodies, which harm aquatic lives and the ecology. Thus, governments and society must take responsibility and initiate actions to minimise environmental harm, protect and preserve the watersheds, curb the overuse of agrochemicals, and preserve water quality and the environment for current and future generations.
EMPIRICAL EVIDENCE ON THE CURRENT CONDITIONS OF WATER RESOURCE INFRASTRUCTURE...indexPub
Water is an essential and critical resource for human, animal, and plant survival and continued existence on planet Earth. Water is increasingly becoming a scarce resource; however, the issue of water scarcity has been exacerbated by the intensity of climate change conditions as well as aging water resource infrastructure in many countries, more especially in developing countries such as South Africa. Therefore, there is an urgent need to upgrade water resource infrastructure in South African cities in order to alleviate the stress on the current systems in place.
An Urban Design Approach to a Sustainable Compact City in New Growth Potentia...drboon
Existence of Cities always depends on the region for the resources-land, food, water, energy or maybe cheap labor. The resource base is vital for the survival of the cities. With increasing urban sprawl there is a great impact on the future of cities and their sustenance. The primary intent of the study is to demonstrate an Urban Design approach towards a sustainable compact urban model in new growth potential areas (case of Cyberabad, Hyderabad, India) as a means to counteract city’s faceless sprawl and environmental degradation by generating compact high density, low energy, mixed-use living and integrating it with the existing city fabric reducing the ecological footprint for future generations. As the selected site offers good natural features, ecologically sensitive areas of the site i.e. Steep slope areas, catchment channels and climatically unsuitable areas from the open space system of the development. The sustainable compact city design approach balances the environmental loads and the growth of city saving resources, conserving energy and enhancing the quality of life.
Riverside Population in Amazon: Culture, Environment and Construction TechniqueIJERA Editor
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.

Brownfield Sites as Catalysts for Sustainable Urban Regenerationand the Deman...IEREK Press
Almost two decades today, the topic of brownfields has extensively been researched in urban sociology, urban planning, and human geography, and numerous Western-Centric studies have linked the redevelopment of the abandoned, contaminated, vacant or derelict sites to sustainable urban regeneration and achieving smart cities and sustainability goals in general. Yet, until this day, the concept has received little academic and practical attention in Middle Eastern contexts. Western contexts on the other hand including Europe, UK and USA continue to offer unique perspectives on approaching brownfields in ways that reduce the alarming spatial cluttering and address socio-spatial disparities and spatial segregation in addition to achieving economic and environmental goals, and similar to the global scene, brownfield sites make a large portion of the post-industrial city of Amman, the capital of Jordan. However, with the lack of a systematic definition for the urban phenomenon objectives, methods to identifying potential brownfield sites and evaluating the prioritisation of their redevelopment that takes into consideration context particularities, and with the absence of participative approaches that include the local community in the decision-making regarding these spaces, city planners fail to include the increasingly growing number of brownfield site that proliferate their cities in the urban planning practice. Through the examination of literature discussions on objectives, approaches, classification systems, methodologies, assessment and evaluation tools for the support of design and prioritising decisions for brownfield regeneration indifferent contexts, and through looking at the numerous potential alternatives for brownfield sites regeneration these contexts highlight, this paper bids to emphasise the importance of developing context specific, localised tools tailored for the Middle Eastern case. Building on the above, this paper identifies five potential brownfield typologies in the context of Amman; (1)residual planning outcomes; (2) discontinued mines and quarries; (3) unfinished mega-projects; (4) contaminated and hazardous sites, and; (5) miscellaneous abandoned sites and buildings, and ends on the note that looking at the increasing demand to meeting smart growth and sustainability needs, these urban landscapes may function as catalysts for achieving comprehensive sustainable urban regeneration.
Natural Urban Heritage and Preservation Policies: the Case of Kyoto’s Waterways.IEREK Press
The value of natural heritage within urban areas is nowadays gaining recognition, but there are still no clear reference frameworks to confront the complexities of their management. In this discussion, the challenges of the association of historical preservation and urban nature are explored through the analysis of the management of Kyoto’s waterways. The conflicts caused by the rapid modernization of Japan at the end of 19thcentury find in Kyoto a remarkable expression in the tensions between renovation and conservation, providing a fertile frame for discussion. Relevant achievements and shortcomings of Kyoto ́s experience are here analyzed, considering how the preservation of historic landscapes affected the protection of urban rivers, the relationship between sustainability and heritage, and the new environmentally aware approaches to river improvement.

Brownfield Sites as Catalysts for Sustainable Urban Regenerationand the Deman...IEREK Press
Almost two decades today, the topic of brownfields has extensively been researched in urban sociology, urban planning, and human geography, and numerous Western-Centric studies have linked the redevelopment of the abandoned, contaminated, vacant or derelict sites to sustainable urban regeneration and achieving smart cities and sustainability goals in general. Yet, until this day, the concept has received little academic and practical attention in Middle Eastern contexts. Western contexts on the other hand including Europe, UK and USA continue to offer unique perspectives on approaching brownfields in ways that reduce the alarming spatial cluttering and address socio-spatial disparities and spatial segregation in addition to achieving economic and environmental goals, and similar to the global scene, brownfield sites make a large portion of the post-industrial city of Amman, the capital of Jordan. However, with the lack of a systematic definition for the urban phenomenon objectives, methods to identifying potential brownfield sites and evaluating the prioritisation of their redevelopment that takes into consideration context particularities, and with the absence of participative approaches that include the local community in the decision-making regarding these spaces, city planners fail to include the increasingly growing number of brownfield site that proliferate their cities in the urban planning practice. Through the examination of literature discussions on objectives, approaches, classification systems, methodologies, assessment and evaluation tools for the support of design and prioritising decisions for brownfield regeneration indifferent contexts, and through looking at the numerous potential alternatives for brownfield sites regeneration these contexts highlight, this paper bids to emphasise the importance of developing context specific, localised tools tailored for the Middle Eastern case. Building on the above, this paper identifies five potential brownfield typologies in the context of Amman; (1)residual planning outcomes; (2) discontinued mines and quarries; (3) unfinished mega-projects; (4) contaminated and hazardous sites, and; (5) miscellaneous abandoned sites and buildings, and ends on the note that looking at the increasing demand to meeting smart growth and sustainability needs, these urban landscapes may function as catalysts for achieving comprehensive sustainable urban regeneration.
Natural Urban Heritage and Preservation Policies: the Case of Kyoto’s Waterways.IEREK Press
The value of natural heritage within urban areas is nowadays gaining recognition, but there are still no clear reference frameworks to confront the complexities of their management. In this discussion, the challenges of the association of historical preservation and urban nature are explored through the analysis of the management of Kyoto’s waterways. The conflicts caused by the rapid modernization of Japan at the end of 19thcentury find in Kyoto a remarkable expression in the tensions between renovation and conservation, providing a fertile frame for discussion. Relevant achievements and shortcomings of Kyoto ́s experience are here analyzed, considering how the preservation of historic landscapes affected the protection of urban rivers, the relationship between sustainability and heritage, and the new environmentally aware approaches to river improvement.
Urban Public Space Axis Rector of Green Infrastructure in the Current City of...IEREK Press
The current city calls for the reconsideration of a close relationship between gray infrastructure and public spaces, understanding the infrastructure as a set of items, equipment, or services required for the functioning of a country, a City. Ambato, Ecuador, is a current intermediate city, has less than 1% of the urban surface with use of public green spaces, which represents a figure below the 9m2/ hab., recommended by OMS. The aim of this paper was to identify urban public spaces that switches of green infrastructure in the city today, applying a methodology of qualitative studies. With an exploratory descriptive level analysis, in three stages, stage of theoretical foundation product of a review of the existing literature, which is the theoretical support of the relationship gray infrastructure public spaces equal to green infrastructure. Subsequent to this case study, discussed with criteria aimed at green infrastructure and in the public spaces of the study area. Finally, after processing and analysis of the results, we provide conclusions for urban public space as a definition of the green infrastructure of the current city of Latin America; in the latter, the focus is to support this article.
Revitalization Strategy for Historic Core of AhmedabadIEREK Press
In India, dense historic urban settlements were developed with the intention of provision of spaces for adequate engagement of the people. Public squares and streets became important places of interaction. ‘Historic core,’ especially had public spaces meant for various socioeconomic groups. Ahmedabad city is a blend of a harmonious past and a vivacious present. Number of historical and architecturally important buildings were built during Muslim and Moghul rules. One of the first built structures within the walled city is the Bhadra fort, a citadel founded by sultan Ahmed Shah in 1411 with a huge public square in front, developed for purpose of procession and gathering. This Bhadra precinct went through various layers of transformation in different eras and now have become vulnerable due to congestion and encroachment. Though, a need for intervention was felt to bring back the lost vitality of the Bhadra precinct, it was realized that a comprehensive approach would be the necessity. Conservation and sensitive development approach was taken to tackle this problem through pedestrianization of the Bhadra precinct, rerouting of traffic and restoration of Bhadra fort. Larger level traffic and parking issues were also considered be-yond the site. Alternative use of Bhadra fort as tourist information center was considered. Urban design guidelines were proposed for harmonious development in the surrounding area. This proposal was considered for funding under Jawaharlal Nehru National Urban Renewal Mission(JnNURM)and was implemented. Many issues were faced during implementation of Bhadra project due to contextualization of informal commercial, religious and other cultural activities. Political, social and administrative factors also played immense role in implementation of proposal. Now since Ahmedabad has achieved the status of World Heritage City through UNESCO certification further implementation of this project will be relatively easy due to envisaged strong political and administrative support.
Unlocking the Potentials of Urban Architecture in Enhancing theQuality of Urb...IEREK Press
Currently more than half of world population are living in cities, while world is witnessing a rapid urbanization process particularly in cities of the developing and emerging countries, where urban poverty areas (UPA) with low quality of urban life (QUL) and lack of the usual urban spaces are the most significant urban phenomena that characterized those cities. In such an urban context there is a need for an efficient tool that contributes positively to the enhancement of the QUL, meanwhile to provide the best use of the rare vacant lands. This study argues that urban architecture as a design field offers a distinctive approach to a special type of buildings made for an urban setting, thus it can enhance the QUL in UPA through community projects. The study is based on an analytical study of selected cases of community projects in UPA that represents examples of how urban architecture through its potentials has a positive impact on its urban context, notably through community projects that strongly linked to real community needs. The results showed that urban architecture as a design approach for community projects have multiple roles that boost the socio-economic daily life, as well it supports various environmental issues towards better QUL.
The Sinkhole Occurrence Risk Mitigation in Urban Areas for the Historic Salt ...IEREK Press
The present research focuses on the definition of a novel methodology for sinkhole risk assessment above shallow salt mines. The research were carried out on the area above the Wieliczka salt mine, a World Heritage site. The study of vertical stresses on the basis of a theoretical state of rock mass deformation in the area of test chambers was performed. Furthermore, the risk of chamber collapse due to ventricular stress exceeding the limit specified in the zone were calculated based on the arch pressure theory. The final stage of the research consists of spatial analysis that leading to the identification of chambers potentially influenced by other risk factors. The research shown in the article strongly suggests that combined spatial analysis with geotechnical analysis may lead to reliable sinkhole risk assessment methodology.
In Search of a Tool to Support Planning Inside Large Cities: the SustaIn-LED ...IEREK Press
The aim of the present study is to investigate the linkages between local economic development, innovation, and environmental sustainability inside urban areas. Can innovation affect the improvement of the quality of life inside urban areas? This research question comes from the consideration that usually innovation and growth in general are considered sources of conflict in affecting the livability of large cities. The objective of the paper is to design a model — the “SustaIn-Led” - to connect levels of environmental sustainability, quality of life, and economic development inside metropolitan areas, taking into account also innovation processes, activated by the innovation policies and by the knowledge economy. The study takes in consideration the 53 largest United States metropolitan areas with a population over 1 million, with a time series from the years 2000 through 2015.This has been done because of a two-fold reason: (1) the US among high-income countries is the one with the highest number of universities, patents, and citations; (2) several studies have shown that innovation occurs in large cities. The first part of the present study has carried out the identification of the variables to represent and significantly explain the phenomena – local economic development, innovation, and environmental sustainability – linked to the design of the SustaIn-LED model. Environmental sustainability in urban areas in this paper is represented by means of the Air Quality Index (AQI),while the number of workers synthetically quantifies local economic development. Correlation and multiple regression analyses are conducted in order to examine the relationship between the three main indicators. The multiple regressions for the year 2015 produced a low p-value, indicating that the predictors are significant in the regression analysis. Similar results of p-value are shown in all the years from 2000 to 2013. For 2015, the results showed that part of the variance in the measure of total workers of the metropolitan areas could be predicted by measures of innovation and air quality. Higher R2values have been registered for the years from 2000 through2013.The development of the SustaIn-LED model could be utilized in urban regeneration processes to help in the design of new urban planning policies inside large cities by means of a better comprehension of environmental and economic implications caused by the implementation of innovation policies.
Estimation of Coating Materials Contribution to the TVOCsEmissions of Wood Fl...IEREK Press
Based on the increasing concern about the exposure to volatile organic compounds (VOCs) from indoor finishing materials, industrial companies are called to meet the growing demand for more sustainable products. Recently, most designers and consumers have more environmental considerations while selecting the finishing materials. These considerations are related to the VOCs content of the finishing material itself regardless of its coating layers. Nowadays, interior wood coatings are commonly applied to large surfaces (ceilings, walls, floors) and many types of furnishing, leading to a high loading factor (surface-to-volume ratio). These coatings might contribute significantly to the VOCs emissions due to repeatedly and periodically use during maintenance, remodeling, and renovation of interior spaces. The aim of this study is to estimate the wood coating materials contribution to the TVOCs emissions of wood product in the indoor environment to shed light on the importance of comprehensive analysis of wood material with all treatment coatings. So, a small interior space with controlled temperature, relative humidity, and air exchange rate was simulated using IA-Quest program to investigate the influence of three wood coating materials; stain, wax, and varnish which were applied to an area of natural hardwood Oak floor. The TVOCs emission data resulted from the different coated wood floor was compared with VOCs emissions caused by the natural wood floor to find out the coating material contribution in TVOCs emissions of a wood flooring material
Sustainable Park Landscaping as an Approach for theDevelopment of the Built E...IEREK Press
Implementing sustainable principles when landscaping parks is vital for the development of the built environment, and should take into account environmental, social, economic, and cultural aspects, in order to eliminate conflict between developmental requirements, and the need to preserve cultural and natural resources. This paper reviews the guidelines that should be considered for current and future sustainable parks in regions with a moderate climate, in order to ensure that they incorporate ecotourism, cost effective operation and maintenance, a clean environment, the promotion of renewable energy, and resource preservation. A number of parks, located in moderate climate zones, are studied in terms of aspects such as their location, topography, operation, and landscaping characteristics, to demonstrate the prevailing normative values that can be applied to sustainable park design. Prince Meshari Park, in Al-Baha city, Saudi Arabia, is employed as a case study for applying all of the guidelines proposed in this investigation, and to highlight some of their merits and limitations in terms of the current situation of the park.
Load Shifting Assessment of Residential Heat Pump System in JapanIEREK Press
With the economic growth and increasing requirement of indoor thermal comfort, the load of building sector presents a greater variability. This paper aims at analyzing the energy consumption characteristics and influencing factors of the residential heat pump system. Firstly, we selected residential households as investigated objective in Kitakyushu, Japan, and compared the energy saving performances of heat supply systems between heat pump and natural gas boiler. The results were based on real measured residential load during winter period, and calculated the cost saving performance of residential heat pump system compared with traditional natural gas boiler. We also did a survey of residential occupation behavior for the 12 selected residential customers. The result indicated that there was low relationship between power consumption and occupation hours, and the number of family members had a significant impact on the power consumption. The results indicate that residential heat pump system presented promising energy saving and cost reduction potential
A Model Proposed for the Prediction of Future Sustainable Residence Specifica...IEREK Press
In Egypt, people are unable to determine the qualities of appropriate residence that achieves quality and occupant satisfaction, and contributes to sustainability of residential conglomerations. In general, developing countries lack housing information which can be used to enhance quality of residence. Also, the methods of assessing and identifying the appropriate criteria for future residence quality remain traditional ones that cannot address the multiple, conflicting, overlapping aspects to reach a good decision. This calls for using the Analytical Network Process (ANP), an effective tool for specifying the relative importance of all factors impacting a specific issue for making an appropriate residential decision. In addition, this method provides results for the decision element impacts network within the decision structure; thus contributing to more understanding of the mechanisms and requirements of residence selection. The proposed decision structure comprises a two-level network: main clusters, main elements, and sub-elements included in the demographic characteristics group, the residence criteria group, the demand parameters group, the supply parameters group, the residence specifications group, and the alternatives group which representing, in total, the decision and specifying the percentage needed for each housing level. Results of the model showed complete capacity in smoothly addressing complexities and overlapping in the decision structure. The decision structure showed that 52% chose luxury residence, 28% chose middle-class residence, and 19.5% chose the economic residence. Mechanisms of decision making were analyzed; particularly in terms of relationship to demographic characteristics and residence specifications. Also, the importance and impact of demand / supply parameters in reaching decision were analyzed
Development of an Open-Source Water Consumption Meter for HousingIEREK Press
This article reports on the project "Design and development of water and gas P.L. measurement devices in the housing: an approach to sustainable consumption in Mexico", prepared at the Metropolitan Autonomous University in the Department of the Environment, whose objective was to develop a device to measure water consumption in the housing, which allows users to know their spending and can make decisions in favor of efficiency through the reduction of water use in household activities. The meter is made up of open source, programmable or reconfigurable software, which receives the signal from a water flow sensor and a casing designed to contain the hardware and facilitate the user's installation. Both the hardware and the casing can be purchased, downloaded, manufactured and assembled at home (Do It Yourself). As specific results were obtained: hardware programming and housing design and as a final result: the assembly of the functional prototype with which measurements of water consumption were made in a housing in Mexico. With this work we conclude that through the development of new accessible and common measurement technologies for the users of a house, it will be possible to promote efficiency in the use of natural resources in cities, increasing availability and promoting a more sustainable urban development.
Multi-Scale Assessment of Urban Gardens as Constructed Habitats for Biodivers...IEREK Press
Biodiversity in arid urban environments depends upon habitat formation that balances both bioclimatic and biophysical environment needs. There is the potential for urban gardens to establish symbiotic ecosystem services from microhabitat formation that collectively form an assemblage of ecological patches to connect a diverse range of flora and fauna, and establish community driven nursery and seed collection initiatives. This study of urban garden habitats situated within a new urban district of Jeddah Saudi. The analysis concentrates on the ability of garden spatial formations to construct a heterogeneous spatial morphology of sub-patch within the larger urban landscape patch. Patch and subpatch formations are examined based on the criteria of (I) assemblage of the spatial habitat (characterized by shape and spatial organization); (II) integration of spatial, functional and vegetation plantation patterns; (III) connectivity. Findings reveal that garden layout is structured by the integration and layering of plant types to generate cool understory habitat with seedling establishment, and water conservation. Designed layout of the garden as a spatial pattern is augmented with a range of microclimate mediators to dim solar exposure within the plantation habitat. A strong heterogeneity in plant formations and combinations is seen to dominant the garden formations.
Architectural Education for Sustainable Urban RegenerationIEREK Press
Urban regeneration is one of the important agendas of Turkey as a developing country. Rapid urbanization problems have been causing vital social and economic problems together with physical and spatial ones especially in big cities of Turkey. Thus, national and local governments handled urban regeneration as a practical method for solution of these problems. However, they unfortunately don’t implement urban regeneration according to its real requirements. Instead, this multi-dimensional and complex process is seen as a pull down and built up operation. Considering this situation and being in awareness of the responsibilities of architects throughout urban regeneration process, the authors think that urban regeneration should be discussed in the scope of architectural education. This paper presents the purpose, the process and the products of an undergraduate architectural design studio that was undertaken at Bursa Uludağ University, Faculty of Architecture. The architectural and urban design projects of the students of which aim was to offer a livable and sustainable mixed used living environments are discussed together with their conceptual backgrounds. Putting stress on the differences between theory and practice, the conclusion introduces a critical evaluation of urban regeneration and sustainable housing concepts in Turkey.
Typology and Solar Gain Analysis: Vernacular Courtyard Houses of Tabriz, IranIEREK Press
The study presents the results of typological analysis and simulation modeling analysis of traditional courtyard residential houses in the cold semi-arid climate of Iran. The purpose of the research has been to analyze and evaluate traditional passive environmental strategies and their elements to provide implications for the design of sustainable residential buildings in contemporary time. Five existing traditional courtyard houses in the city of Tabriz, Iran, are used as case-studies to analyze the typology and the solar zoning conditions and to develop simulation models. The Ecotect simulation program is used to calculate the solar gains of the buildings and to analyze the effectiveness of the natural passive systems along with native design strategies in terms of potential solar gains of main and secondary living spaces. However, in the vernacular, not only the awareness of the climatic and topological considerations is important, but also the values, rituals, and beliefs that shape the design of the dwellings need to be considered. The research is based on the hypothesis that vernacular buildings (courtyard houses) of Iran have been environmentally sustainable structures. However, an important challenge of the study has been to avoid the technological bias and to consider the cultural and social aspects and embodiment of the studied houses, as well. The study also addresses the potential short comings that limit the reliability of Iranian vernacular architecture at present in order to arrive at a more holistic understanding of the sustainability of the vernacular architecture in the country.
Lessons Learned from the First Passivhaus Building in QatarIEREK Press
Energy efficient models have become the path to reduce energy consumption and Greenhouse gas emissions in the built environment in many developed countries. According to the Energy Performance of Buildings Directive (EPBD), new buildings constructed within the European Union (EU) countries are expected to be nearly zero energy buildings (nZEBs) by 2020, while new public buildings are expected to adhere to this target by 2018. The Passivhaus approach has been identified by several researchers as a possible roadmap to achieve nZEBs. The meticulous engineering and high standards of the Passivhaus building fabric, in addition to the high comfort levels, are the main reasons behind the success and widespread of the standard. Recently, in 2013 the Passivhaus principles have been applied to an experimental residential project in the hot and arid climate of Qatar. The project is composed of two identical buildings, one built according to the Passivhaus standard and the other according to normal practices in the country. The thermal performance and comfort levels of both buildings were assessed through dynamic simulation and on-site measurements. Results indicated that at least 50% reduction in annual operational energy, water consumption, and CO2 emissions were achieved in the Passivhaus model in comparison to the standard model. This paper aims to highlight the lessons learned through the Passivhaus project; first by exhibiting the Passivhaus criteria that have been met, second by showcasing the outcomes of the project, and third by displaying the barriers and difficulties that have been associated with building according to the standard in Qatar. Finally, recommendations and general guidelines are suggested towards a possible adoption of the Passivhaus standard in Qatar and the Gulf Cooperation Council (GCC) countries
Optimal Sizing and Design of Isolated Micro-Grid systemsIEREK Press
Micro-grid and standalone schemes are emerging as a viable mixed source of electricity due to interconnected costly central power plants and associated faults as well as brownouts and blackouts in additions to costly fuels. Micro-Grid (MG) is gaining very importance to avoid or decrease these problems. The objective of this paper is to design an optimal sizing and energy management scheme of an isolated MG. The MG is suggested to supply load located in El-shorouk Academy, Egypt between 30.119 latitudes and 31.605 longitudes. The components of the MG are selected and designed for achieving minimum Total Investment Cost (TIC) with CO2 emissions limitations. This is accomplished by a search and optimization MATLAB code used with Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) techniques. The use of Diesel Generators (DGs) is minimized by limiting the gaseous CO2 emissions as per targeted allowable amount. A comparison is accomplished for investigating the CO2 emissions constraints effects on the TIC in $/year and annual cost of energy in $/kWh. The obtained results verified and demonstrated that the designed MG configuration scheme is able to feed the energy entailed by the suggested load cost effectively and environmental friendly.
Regenerative Mobility: Disruption and Urban EvolutionIEREK Press
Mobility plays an important role in the cities by enabling people to carry out the most varied activities across the territory, as well as to ensure the city fully function. In addition, analogies to the human organism can be made by this urban dynamic, looking for solutions to specific issues. Moreover, this paper has been based by the premise that phenomena and urban elements could be conceptualized, explained and transformed from contemporary and innovative approaches applied in the medical field. For this reason, this paper aims to develop and present a new concept associated with urban mobility, based on the principles of regenerative medicine: the Regenerative Mobility, a concept with disruptive and evolutionary purposes. Furthermore, the structure of this paper is summarized by the introduction which contextualizes the theme, presents and characterizes the techniques used in the research. Additionally, the following chapters explore essential aspects of the city, explaining why it needs a mobility change and new concepts. Therefore, the concept of Regenerative Mobility is presented as a potential of mobility and cities improvement, followed by pragmatic cases, capable of illustrating some of its principles.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

agriculture, forests and floodplains highlight the increasing conflicts between the landscape and the occupants.
Haphazard urbanisation and post-earthquake reconstruction have also increased water extraction, removal of topsoil
for brick manufacturing, and riverbed sand for construction.
Additionally, fossil fuels used in the construction industry contribute significantly to the valley's deteriorating
environmental quality (Raut 2003; Uprety et al. 2019). Declining soil quality, water shortage, climate change and
post-earthquake distress are also impacting the traditional farming and animal husbandry sectors. Figures 1a-1f
provide glimpses of the ongoing transformation in the form of housing, infrastructure, and urban expansion. The
periphery's role is critical, as it preserves the agricultural landscape managed by the traditional farming communities.
In addition, Kathmandu is further exposed to water shortages, growing air pollution, and forest cover's destruction
(DiCarlo et al. 2018; Pradhan et al. 2007). Increased urbanisation results in waste generation, which further impacts
the peripheral landscape (Alam et al. 2008; Dangi et al. 2011). The increasing environmental challenges, underlying
risks of recurring earthquakes, and the projected urbanisation of the valley add to its vulnerabilities. This research
investigates one of the predominantly agricultural peripheries, transforming rapidly to accommodate the urban growth
and located in the southern fringe of the Kathmandu

This research analyses urbanising regions such as Kathmandu within the Himalayan region. It aims to reveal the
ecological distress, ongoing contestations and reduced resilience in adapting to climate change in the Himalayas
(Eriksson et al. 2009). It attempts to highlight the challenges of mountain communities that require awareness and
innovative response towards environmental change. The study contours the critical issues of the landscape in response
to the following questions. First, can a landscape-led recovery guide the future urbanisation in Kathmandu? Second,
can design research help in capacity building in the post-earthquake rebuilding efforts? The paper builds upon the
premise of landscape urbanism's ability to offer alternative land-use planning methods using resource potentials
within an urbanising context.
2. Methods and materials
The paper combines interdisciplinary learning, cartography and design research to explore future opportunities within
a rapidly urbanising territory. The theoretical lenses of landscape urbanism and concepts of systemic design have
been combined to analyse the productive landscape and develop design scenarios. The fieldward and primary data
collection for this research was conducted during the post-disaster mission to Nepal after the 2015 Gorkha earthquake.
A detailed spatial investigation was conducted on a study frame of 8 km by 6 km. Observations were collected through

maps were prepared by combining open-source geospatial data, archival data and numerous photographs.
Interpretative mapping synthesised the opportunities, conflicts, and risks for guiding future urbanisation through
spatial design. The statistical and quantitative data was estimated from archival research, case studies, peer-reviewed
articles and expert interviews. The author does not claim complete accuracy of the quantitative data presented but
provides an accurate representation of the ground conditions and possible opportunities. The results are discussed in
two parts. Section 3 provides insights into the dynamic qualities of the landscape and transforming relationships over
time. It helps identify typologies, wasted potentials and opportunities that guide design strategies. Section 4 describes
the various design strategies that integrate the historical qualities, combining latent landscape qualities and human
ingenuity possibilities through cooperation. The research concludes by reflecting on disasters and how post-disaster
reconstruction efforts can stimulate urbanisation as a dialectic process between existing and new development.
3. Assessment of landscape resources within a productive periphery
Since its origins, the valley's geography has been instrumental in Kathmandu's resource flows and development. The
unique bowl-shaped valley also impacts the availability of essential resources. Figure 2a-2c constructs the flows of
resources (energy, fuel, water, food and waste) while allowing us to study the urban functioning of Kathmandu within
Nepal. By following the material flows, it is possible to understand the system's functioning and its weaknesses. It
can be concluded that the high there is external dependence that is vulnerable due to the valley's position. The material
flows are also subjected to the long-distance relationship between material and user through transport corridors
subjected to earthquakes and political blockades. Most internal flows are subjected to vulnerabilities due to
urbanisation, lack of water, and climate change impacts.

This section investigates specific cases but positions them to critically review the ongoing transformations of
landscape typologies within the landscape. A detailed spatial investigation has been conducted upon an urbanising
periphery near Bungamati and Khokhana, 15 km south of Kathmandu. The research utilises a 'framework' measuring
8 km by 6 km to explore the research questions and possible design strategies. The frame is bound by the rivers and
mobility corridors and defined by the valleys of Bagmati, Nakkhu, Kodhku and Godavari rivers, as shown in Figure
3a. The land use in the frame is mainly agricultural, its population involved in farming and crafts, and its landscape
threatened by the uncontrolled, mushrooming practices which induce sprawl. The investigation frame is further
threatened by urbanisation and future mobility projects, such as the ring road, the Fastrack expressway and a rapidly
growing brick industry to support the post-earthquake redevelopment that rapidly consumes Kathmandu's southern
periphery. Figure3b-3e illustrates the composition of the landscape. The agriculture practices alternate between dry
and wet seasons, irrigated and non-irrigated and the village slopes. Water needs for agriculture and animal rearing is

met chiefly through rainfall, artificial ponds and indigenous water canals. Urbanisation and land-use changes have
aggravated the loss of irrigated land by the destruction of the water system. Most of the agricultural periphery present
during the 1950s has been consumed by urbanisation along the ring road and continues to date (Shrestha 2013). It
further explores the spatial impact of interaction among the natural and human resources. It reveals multiple overlaps
of daily and socio-cultural rhythms of life within the valley. The research draws relations between the interplay of
ecological and socio-economic activities, intending to highlight associated meanings and collective action related to
production and consumption. The periphery produces many products based upon the location of raw materials. Each
product has distinct or overlapping cycles due to its manufacturing processes, scales of operations, and labour
availability, including its impact on the region's social structure. Yet each product draws upon the capacity of the
natural and human resources potential within the study frame.

Figure 3a, shows the productive valleys, traditional settlements and suburbs along roads, brick kilns and farmland
within the 8 km by 6 km investigation frame. Productive flows concentrate along with the villages, and the critical
mobility corridors connecting convey the finished products to markets located within the city. The fieldwork and
mapping revealed that bricks and sand mining were some of the most harmful practices within the landscape. Many
subsistence products and local sales, such as livestock management, floriculture and cooperative farming, require
technical upscaling as their efficiency dramatically depends on water and soil. Figure 3b-3e highlight the key
typologies related to production and resource management. These typologies were distinguished into subsistence
agriculture, small scale animal and vegetable farms, commercial farming, and brick kilns during the fieldwork. These
print plates are engaging themselves over the base layer of the valley landscape, and they become the producer,
processor and consumer of resources. The resource flows' spatial position can provide clues towards continuities,
disruptions, scattered, or concentration. It reveals meanings associated with collective actions related to resource
availability and productivity, including workforce patterns provided by individual farming households, often by
migrant labourers.
The impact due to resource extraction is increasing daily due to demands for the growing city. The irrigated lands are
getting impacted by the soil extraction for bricks. The loss of irrigation is coupled with water extraction of
groundwater by commercial vegetable farming enterprises. They reduce farmlands' productivity, and climate change
also impacts farmers to opt for fertiliser-based farming practices. The existing production practices are simultaneously
removing soil fertility and also depositing chemicals within the landscape. The post-earthquake rebuilding frenzy has
already accelerated the brick making and construction industries, further threatening landscape qualities. Yet, these
mobilisers of the landscape have significant potential if guided within a framework of cooperation. Further
5. Manna/ Environmental Science and Sustainable Development

investigation on resources revealed that these landscape mobilisers leave significantly underutilised or wasted
opportunities within the landscape. Available as latent, leftover or wasted, these material and human resources can
be utilised in meaningful ways. Wasted resources were classified into; crop residues, waste or losses from
commercial, cooperatives and animal farms, wastewater from residential areas, residual heat and unutilised workforce
from the brick kiln and transport network poor producer-consumer relationships. Figure 4a-4d presents the interpreted
wasted potentials, which can be devised into resource-based recovery processes providing the much-needed
opportunities for sustainable growth of the valley's periphery. Figure 4a becomes the underlying basis for three key
design strategies elaborated in the next section. The resource system analysis highlights the importance of landscape,
traditional villages, and specialised markets as equally crucial to the valley's urbanisation. It also highlights
environmental degradation, deposition of chemicals, topsoil loss, increased carbon emission, and linear systems
creations.

4. Connecting resources, envisioning a systematic transition through strategic projects
Highlighting the spatial relations and underutilised capacities of the landscape previously, the following section
elaborates upon three incremental design strategies linked to resource pooling and community collaborations. These
projects combine landscape urbanism and systemic design principles to synergise the desired transition (Berger and
Sijmons 2009; Shannon 2009). The village armature project reimagines the existing household-farm relationship into
an upscaled resource grid connecting Bungamati and Khokhana. It combines the key public spaces, social and
educational institutions, waste collection points, sewage outfalls, and the various crafts/small workshops along its
length. Household night soil and biodegradable waste are converted into biogas, and manure for the kitchen gardens
are enhanced with an anaerobic digester. The strategy allows an average household of five members to extract usable
energy in biogas at 2kwh/household, thereby removing methane from the environment and leaving usable manure of
approximately 0.3kg/household. It is estimated that household utilisation of 3 kg of wood per day for energy can be
covered by the biogas plant (Rijal and Yoshida 2002). The strategy is scaled from household to village level with the
help of the compact urban form of the villages (Thomsen, Woerum, and Haagensen 1968). Village or cluster digestors
can replace individual anaerobic digesters, increasing efficiency and reducing capital and operational costs. The
centralised facility fosters participation and assists in post-disaster rebuilding efforts through efficient energy-nutrient
relationships, as illustrated in Figure 5.
The armature further pools solar energy at the rate of 4kw/10sqm of rooftops as additional electricity to the craftsmen
to overcome electricity shortages (Jha, Stoa, and Uhlen 2016). Analysis of energy bill during the fieldwork revealed
6. Manna/ Environmental Science and Sustainable Development
pg. 19
that the average household and a craft cluster utilised approximately 8 kWh of energy per day. The combined
efficiency of the household biogas at 2kWh (Voegeli 2014) and rooftop solar of 4kWh/Sqm (Gautam, Li, and Ru
2015; IRENA 2014) can suffice for most of the energy needs. In the future, the armature can support craft tourism
and enable densification. The microgrid allows resource pooling and distribution for energy (solar & biogas),
extracting valuable nutrients from human waste as manure for agriculture and promoting agriculture and crafts within
energy scarce rural areas. The nature and position of the armature allow us to think beyond its social and spatial
capacities, where solid waste, wastewater and energy production, and consumption become the critical elements of
the resource armature. It incorporates the existing small-scale infrastructure, with investment from participants and
subsidies from renewable energy projects to supply the energy collected from the community biogas digester and
rooftop solar harvesting. Solar harvesting through rooftop collection produces power for the production units and
institutions. The surplus energy can be conveyed to the micro-energy grid, benefiting the small-scale commercial
enterprises along the armature. As a collector and generator, a microgrid enables capacity building through pooling
its resources, serve as a future tourist trail and enable incremental densification. It will promote upscaling and new
economies along the armature, as visualised in Figure 6a-6c.

The second project demonstrates medium-scale strategies by combining agricultural production, cooperatives, and
brick kilns. The brick industry's unidirectional resource flows are a threat to the landscape at large. The brick kilns
are temporal and change their location after every seven to ten years. Within this period, they exhaust the fertile
topsoil essential to local farmers. The entrepreneurial character of the brick kilns combines capital and workforce in
altering the landscape. The brick kilns' position and movement can be structured positively for guiding the flow of
resources within the landscape. Two different sites were chosen for demonstration, one close village and the second
along the ring road were selected to test the brick kilns as a hybrid resource management centre. The waste heat from
the brick kilns can be utilised for dehydrating and preserving farm produce or incinerating crop wastes, farm waste
and household biodegradable waste. On average individual brick kilns results in wasted heat of 25,000mj by burning
a tonne of coal in producing between 8000 to 10000 clay bricks within Nepal (Shah and Nagpal 1997). It was
calculated that this wasted heat could be utilised to dehydrate or process 1.0 to 1.5 mt/hr of agricultural waste into
biomass pellets (UNEP 2009). The processed farm wastes can be used efficiently as briquettes for household fuels or
even within the brick kiln. It can be further used to generate electricity, produce biomass pellets or even electricity if
appropriate technologies can be utilised (Kafle et al. 2016; Nilsson, Bernesson, and Hansson 2011). Cooperative farm
units within the proximity can also use the wasted heat and workforce to process the farm produce to increase farm
crop longevity. Such economic cycles and sharing process allows the nearby settlements enable the villages to engage
in entrepreneurial activities and generate additional incomes to offset food costs, promoting food security. The brick
kilns can help recharge the shallow aquifer during the wet season through clay ponds and pump the shallow aquifer
during dry season use, cutting dependencies upon water from irrigation channels significant to downstream farmers,
as shown in Figure 7.

rural and suburban Kathmandu, with capacities to treat agricultural produce, rural and urban household waste. Source: Author.
The suburban demonstration site highlights the potentials of the valley's brick kilns, their resource pooling capacities,
and the city's long-term objectives (Bisht and Neupane 2015). Suburban brick kilns can help deal with waste, as their
heat capacities can be utilised for incineration, drying, and biomass energy production to meet various needs of the
suburban (Shrestha et al. 2014). The energy generated by these kilns can be transferred to the nearby vegetable farms,
which can use this energy for cold storage or food processing. The existing transportation system of both brick supply
and vegetable farming can connect to the city. The resource armature plays a vital role in the systematic structuring
of the landscape. It promotes commercial activities such as recovery from agricultural waste, vegetable processing,
and energy by-products. The phasing of armatures aims to achieve the design strategy's dual goals, where the soil
excavation results in the creation of developable zones at different levels within the valley. These developable zones
can absorb future urbanisation, support the production of high-value crops, and the deepest plinths can be suitable for
pisciculture or paddy cultivation. As a collective strategy, we understand the frame study as a dynamic and ever-
changing region because of the fast urbanisation and external pressure such as landscape risks. As such, we are
8. Manna/ Environmental Science and Sustainable Development
pg. 21
foreseeing a flexible and evolving project that has the means to accommodate future and unpredictable scenarios, as
shown in figure 8a-8d.

The systemic design strategies combine linear resource cycles into closed or shorter, or recurring loops. They
strategize resource management into opportunities for the valley's inhabitants. These strategies draw upon the concept
of sharing and producing energy, managing waste, and playing an essential role in the city's southern periphery's
structured intensification. Agricultural by-products, waste to resources, permanent employment, landscape
management shall provide new livelihood opportunities. Presently increased animal farming and commercial
practices are concentrated along the periphery of the traditional settlements and suburban frame. These farms focus
on high-value food production to supply the city markets and manage the organic waste. Their position along the city
periphery and utilising the market-producer links, the waste can be brought back and converted into helpful animal
feed or manure for farms. Such processes manage biodegradable waste, prevent greenhouse emissions, and promote
new economies that can absorb both the migrant and local populations. The assembly of the design strategies is
imagined as an urban-rural transect. The transect enables resource recovery, fostering cooperation amongst
communities, entrepreneurs, producers, consumers, and local and regional scale. Figure 9a & 9b highlights
collaborative loops across scales that promote resilience within the rural landscape, enabling the communities to gain
self-sufficiency and become a vital partner to the urban areas and provide sustainable resource management
alternatives as a critical role for the periphery. Studies have highlighted the importance and benefits of resource
recovery, waste management, landscape led opportunities to mitigate urban challenges. Though these initiatives are
yet to realise their full potential and can be adopted at large, they highlight appropriate landscape urbanism strategies
to help the periphery become a more vital partner in the city's growth (Lohani et al. 2021; Shrestha et al. 2014).
Returning to the research site in February 2020 revealed that small and medium-sized entrepreneurial activities have
commenced within the study areas to support livelihood and food production. Lack of robust institutional and
financial mechanisms has displayed collaborations amongst producers in waste segregation, composting, poultry and
fish farming recycling benefit from agricultural and farming wastes.

5. Conclusions
The ongoing urbanisation of Kathmandu is a classic example of planning-led expansion in the south Asian context,
where the regional landscape is undermined in planning processes. Kathmandu's landscape has been essential to its
development in the past, and its absence can expose the city' vulnerabilities, exhaust natural resources and impact
livelihoods in future. The transition from a land-use approach into an integrated system requires long term vision,
planning and cooperation among society and planning agencies. Disasters or large-scale shocks bring forth resilient
capacities which enable collaboration and encourage adaptation towards the crisis (Solnit 2010). The earthquake is
an opportunity to reorganise the crisis problem long-term adaptation strategy through planning. Landscape and
systemic design approach argue for sustainable interactions amongst ecosystems; resource flows, human linkages,
which get disrupted due to disasters and climate change, impacting the 'ambitious' urbanisation processes within the
Himalayan region and elsewhere in South Asia. The research advocates urbanism, which evolves like nature, creating
opportunities for small, medium, and large-scale activities to sustainably expand the population. The research also
points towards the importance of data collection, surveys and mapping, identifying key stakeholders, utilising
entrepreneurship and governance structures. Demonstrated design strategies also require the capacity building of the
stakeholders, favourable policies, capital and technological investments to foster the sustainable transition. This
research advocates an alternative to creating new developments with objectives set to enhance the landscape's capacity
by bringing forward its structuring capacity as part of the planning process. The research outlines a possible vision
towards avoiding urban sprawl and takes advantage of the ground reality of fostering a 'reimagined' role of the
periphery.
