This document summarizes a study measuring the effects of calcium silicate (CaSiO3) addition on tree transpiration rates. Sap flow measurements were taken on control and CaSiO3 treatment plots at three sites, with 3 tree species monitored per plot. The results showed that tree species and time of day had a significant impact on transpiration rates. Additionally, the CaSiO3 treatment continued to have a significant effect on transpiration, with higher rates observed in the treatment plots even three years after application. Atmospheric conditions like radiation and vapor pressure deficit also explained a significant portion of transpiration variation.
Sap flow: Calcium, and what about N and P?
This document summarizes research on the effects of calcium (Ca), nitrogen (N), and phosphorus (P) additions on tree transpiration rates. The research found that:
1) A 2014 study found that a one-time addition of calcium silicate (CaSiO3) increased transpiration over the control plots, especially for yellow birch trees. Transpiration rates also varied between tree species and sites.
2) A 2015 study found that adding phosphorus (P) alone decreased transpiration rates in white birch trees compared to other treatments.
3) Overall, the research suggests that calcium and phosphorus can impact forest transpiration rates, with calcium increasing and phosphorus decreasing transpiration
Day 1 - arun bhakta shrestha, arrcc-carissa workshop
1) The document discusses using climate change scenarios to understand current and future water availability in the Hindu Kush Himalaya region.
2) A fully distributed hydrological model was used to simulate river flows under different climate change scenarios through 2050. The scenarios project increases in precipitation and glacier melt that result in mostly stable or increased water availability across the basins.
3) However, communities dependent on glacier and snow melt could be negatively impacted as glaciers recede. Springs that supply water in mountain areas are also drying up in some locations. The document calls for more accurate assessments of climate change impacts.

1) The document analyzes the effects of climate change on glaciers in the Satluj River basin in India using two climate models, CNRM-CM5 and GFDL-CM3.
2) The CNRM-CM5 model projects one of the largest increases in precipitation over the Satluj basin by the end of the century, while the GFDL-CM3 model shows relatively dry conditions by mid-century followed by wetter conditions late century.
3) The researchers use a "change factor" methodology, applying temperature and precipitation anomalies from the climate models to observed historical data to estimate future climate conditions and their effects on glaciers in the basin.

Forecasting monthly water resources conditions by using different indices
Sharp changes in the SWSI are an obstacle for accurate estimation of this parameter. In addition, providing all of the information needed to determine the SWSI is not always possible. The SWE because of effective role in the calculation of the SWSI, it is a viable alternative to forecast instead the SWSI. The obtained results showed that the ARIMA model forecasted the SWE values for January to June successfully. Using these forecasted data and by non-linear regression can be estimated the SWSI values for all points of each basin except in cases that the amounts of SWSI and SWE are very low (drought conditions).
URC 2015 - Carbon Fluxes Across Four Land Use Types
This document summarizes a study measuring carbon fluxes across four land use types in New Hampshire: forest, hayfield/pasture, corn/agriculture, and residential/paved. Researchers are using eddy covariance methods and sensors to measure CO2 fluxes, evapotranspiration, and albedo over these four land use types. Preliminary results from the first year of data collection show differences in CO2 fluxes between the land uses. Understanding these flux variations will help assess the impacts of land use change on local and global climate.

The document describes a study that measured the carbon dioxide exchange of two Arctic shrub species, Betula nana and Salix pulcra, to understand their photosynthetic efficiency. The study isolated individual shrubs using chambers and measured the CO2 flux over time. Aggregating these flux measurements provided data on net ecosystem exchange of CO2 for each shrub. The results showed that the shrubs' photosynthesis was being efficiently optimized rather than inhibited by self-shading, as indicated by an exponential relationship between CO2 exchange and shrub mass. This data could help predict shrub responses to future Arctic conditions by being incorporated into forward models.

This document summarizes a study on the 2010 Pakistan floods. The study used an AGCM model with different SST forcings to determine the roles of ENSO and ENSO-unrelated SSTs. The model was able to simulate observed rainfall anomalies and atmospheric circulation over South Asia when using real 2010 SSTs. Experiments showed that both Pacific La Niña SSTs and Indian Ocean SST anomalies contributed to the extreme rainfall. Pacific SSTs modulated the large-scale monsoon circulation while positive Indian Ocean SST anomalies induced northward moisture transport into northwest India and Pakistan, leading to heavy rainfall. The study highlights the importance of monitoring Indian Ocean variability for improving extended-range prediction of heavy rainfall events over adjacent subtUndergraduate Research Poster
1) The study aims to determine if maximum temperatures can be related to soil moisture levels by analyzing temperature, latent heat, and soil moisture data from flux towers in the western US.
2) It finds that days with low latent heat and high maximum temperatures statistically have drier soils than days with high latent heat and high maximum temperatures at two forest sites, but the opposite at one site.
3) Linear regression models using temperature and precipitation better capture latent heat than models using just soil moisture, showing soil moisture's influence depends on other factors like precipitation.
Water Supply Assessments in Arid Environments, A GIS Solution
This document summarizes a water supply assessment for a proposed 7,700 acre project in the Western Mojave Desert region of California. It outlines the regulatory framework for such assessments, as well as challenges assessing water supply in arid environments with low rainfall and high evaporation. The assessment uses detailed GIS weather data and elevation contours to more accurately calculate mountain front recharge within the project's watershed. It determines that under normal, single dry, and multiple dry year scenarios, projected groundwater recharge would exceed project demand.

This document summarizes research on the impacts of climate change on river basins and hydropower potential in the Hindu Kush Himalaya region. It finds that due to increasing glacier melt and precipitation from climate change:
- River runoff and hydropower potential in the region's river basins are expected to be sustained through 2050.
- Glacier cover is projected to decline 25-50% by 2050, decreasing their contribution to streamflow while rainfall-runoff increases.
- Overall water availability is projected to remain the same or increase, with no negative impacts found on hydropower potential based on an initial assessment.

1) The document summarizes a presentation about the CoupModel, an ecosystem model that couples carbon turnover and climate variability in terrestrial ecosystems.
2) The model includes submodels for water, heat, carbon, and nitrogen processes and their coupling. It has been used to model specific sites and regional scales.
3) Results show soil carbon pools increasing in southern Sweden but remaining steady in central and northern regions, indicating another nitrogen source is needed. Climate change is expected to increase net ecosystem productivity in all Swedish regions mainly through increased tree growth.Global change impacts roland barthel
This document summarizes a large scale integrated modeling study from southern Germany that assessed global change impacts on groundwater and water supply. The study used an integrated modeling framework called DANUBIA that coupled 16 models to simulate regional actor responses to global change in the water domain. The models assessed how climate and socioeconomic changes could impact groundwater recharge, groundwater levels, agriculture, and human decisions around water use and supply. The modeling showed potential declines in groundwater levels and increases in human adaptation responses like expanded water resources or crisis management. The integrated modeling approach provided insights but also had challenges around data needs and computational demands.
Primary Literature Presentation
This study found a correlation between increased climate change-driven droughts and widespread declines in tree crown condition, disruptions to food webs, and increased tree mortality across European forests over a 20-year period. The researchers analyzed defoliation and mortality data from forests in the Iberian Peninsula and found significant increases in crown damage and species-wide impacts associated with more frequent and severe droughts linked to climate change. The results support the hypothesis that climate change is causing more prolonged and intense droughts in northern hemisphere forests, threatening forest health, carbon storage abilities, and economic services like recreation and fuel production.
Exploring_GIS_in_Glaciology
The document discusses using GIS tools to study glaciers and analyze changes in North American glaciers over time. Specific GIS data and tools discussed include Landsat imagery, digital elevation models, slope and aspect mapping, accumulation area ratio analysis, hypsography mapping, and DEM differencing to calculate changes in glacier area, volume, height and annual mass balance for several glaciers between 1948-1995. The analysis shows most glaciers experiencing significant loss of area, volume and negative annual mass balances.

1) Soil aggregates are combinations of soil particles and organic matter that together form larger clumps or granules. Accurately measuring aggregate stability is important for assessing soil health and the impacts of management practices.
2) Current methods for measuring aggregate stability have limitations. This study proposes a new indicator called Integrated Aggregate Stability (IAS) which quantifies the shift in aggregate size distributions and corrects for particle size effects.
3) Testing IAS on samples from two experiments showed it could detect differences in aggregate stability due to tillage practices and cover cropping more consistently than other indicators. IAS provides a standardized way to measure how applied stresses like rainfall or machinery affect soil structure.IUKWC Workshop Nov16: Developing Hydro-climatic Services for Water Security –...

This document analyzes the impact of large-scale climate modes like ENSO, IOD, and SAM on daily and subdaily rainfall characteristics in east Australia. It finds that the occurrence of rainfall events, rather than average rainfall intensity, is most influenced by these climate modes. This is shown to be associated with changes in the time between wet spells. Furthermore, ENSO remains the leading driver of rainfall variability in east Australia, especially further inland during winter and spring. The results have implications for water resource management and how climate models capture rainfall variability.

This document presents a framework for conducting cost-benefit analyses of ecosystem-based climate change adaptation actions in the Carpathian region of Central and Eastern Europe. The framework includes developing vulnerability assessments of ecosystems and habitats to climate change, identifying adaptation measures, quantifying the economic costs and benefits of measures, and conducting stakeholder engagement. A case study will apply the framework to select adaptation measures for vulnerable ecosystems and assess the changes in ecosystem services with and without the measures to inform decision making.Evaluating aboveground terrestrial carbon flux as ecosystem planning
This document evaluates using terrestrial carbon flux estimation models as ecosystem planning tools for the Mt. Kenya ecosystem. It summarizes using the Carnegie Ames Stanford Approach (CASA) model to estimate net primary production and carbon assimilation potential in Mt. Kenya vegetation using Landsat imagery. Key findings include that CASA can capture landscape variability in carbon flux, satellite-derived vegetation indices like EVI are useful for accounting for carbon sinks, and indigenous species show more resilience than agricultural lands, which have potential for increased carbon sequestration. The study also analyzes human appropriation of net primary production across river basins to inform river basin planning.

Hb2015 phelps
This document discusses a study on how nitrogen (N) affects phosphorus (P) resorption and P affects N resorption in plants. Specifically:
1) The study found that P resorption efficiency was highest in plots with higher soil N, while N resorption efficiency was highest in plots with higher soil P.
2) Analysis showed N resorption efficiency correlated with higher green leaf P concentrations, while P resorption efficiency correlated with higher green leaf N concentrations.
3) This provides evidence that resorption of one nutrient is driven by availability of the other nutrient, demonstrating co-limitation between N and P in these forest ecosystems.

Angle of reflection (Architectural Acoustics)
- Sound waves reflect off surfaces similarly to light waves. When a sound wave strikes a large, uniform surface, it will reflect at the same angle at which it hit the surface.
- The law of reflection states that the angle of incidence equals the angle of reflection. Reflected sound waves are always less loud than direct sound waves due to energy absorption.
- Porous, rough, and soft materials absorb sound energy through reflection in many directions rather than coherent reflection, making them sound absorbing rather than reflecting. Curved surfaces can be used to focus reflected sound.

The project analyzed soil and tree data collected from an urban forest area in Chicago. Statistical analysis revealed correlations between various soil parameters. Spatial interpolation maps showed gradients and clusters of nutrients, pH, and lead levels. While tree health was not correlated with soil properties, tree species showed differences in nitrate, phosphorus, and pH levels. The study supports links between soil patterns and aboveground tree processes, and that GIS can help manage and analyze landscape-level ecosystem data.

Use of Fuzzy Set Theory in Environmental Engineering Applications: A Review
Methods of solving the identified environmental problems, considering mathematical rigorous alternative assessment of environmental component process using fuzzy logic and approximate reasoning, are described by various researchers. To illustrate how such a computational intelligence approach would work in performing an assessment, various artificial techniques have been described. Fuzzy system technique for analysis of environmental components differentiates the approach from those techniques used in the past. It takes advantage of advanced computational intelligence techniques such as fuzzy sets and logic, for quantifying and manipulating in a mathematically rigorous way, subjective, inherently uncertain or imprecise values and concepts. This paper put forth the use of fuzzy sets in field of environmental engineering.

Wetland_Presentation.pptx
The document summarizes an ecological assessment of Mai Pokhari wetland in Nepal. It finds that the wetland supports diverse flora and fauna but is showing signs of degradation. Water quality tests and analysis of benthic macroinvertebrates indicate the wetland's ecological quality is only fair, with moderately polluted water. Increased nutrients, organic matter, and changes in land use and cover around the wetland are contributing factors. While still ecologically important, conservation efforts are needed to sustainably manage Mai Pokhari.

Groundwater and River Water Interaction at Ciromban and Cibeureum Riverbank, ...Dasapta Erwin Irawan
The document presents a study on the interaction between groundwater and river water in Tasikmalaya, Indonesia. Water quality measurements from 50 wells along two rivers and 12 river sites were analyzed. The analysis identified two types of water interaction: effluent flow in one river segment and influent flow in the other. Water quality variables like pH, resistivity, and dissolved oxygen showed a clear separation between groundwater and river water. The study provides guidance for further geological modeling of the area to understand water resource management challenges in Tasikmalaya.Authors Response To The Reviewer Comments

Markrecapture versus-lengthfrequency-based-methods-evaluation-using-a-marine-...
This study compares growth estimates of the marine snail Tegula viridula obtained through two common methods: mark-recapture analysis and length-frequency analysis. Over two years, thousands of snails were collected, measured, tagged, and some recaptured to obtain direct growth data for mark-recapture analysis. Monthly length-frequency distributions were also analyzed indirectly. In the first year, the methods produced different growth parameter estimates, likely due to small sample sizes, but estimates were similar in the second year with larger samples. Combining the data produced even more similar results. A new combined methodology is proposed to better estimate growth from tag-recapture data.

Data Preparation for Assessing Impact of Climate Change on Groundwater Recharge
Climate change is a change in the statistical properties of the climate system when considered over long
periods of time. It significantly affects the various components of hydrological cycle like temperature, precipitation,
evapotranspiration and infiltration. All these components together affect the rate of groundwater recharge. So
understanding the effects of climate change on groundwater recharge is the need of time for the management of
groundwater resources. This paper presents the data preparation initiatives and a suitable methodology that can be
used to characterize the effect of climate change on groundwater recharge. The method is based on the hydrologic
model Visual HELP which can be used to estimate potential groundwater recharge at the regional scale. The success
of Modeling depends on the accuracy of data and the mode of collecting the data. Therefore, identifying the data
needs of a particular modeling study, collection/monitoring of required data and preparation of data set form an
integral part of any groundwater modeling exercise. The main objective of this paper is to describe the exact data
required and its preparation to simulate the groundwater recharge using HELP Model Software for Yavatmal as a
study area situated in Maharashtra state, India. The impact of climate change as a pilot study is modeled by using
computer software HELP (Hydrologic Evaluation of Landfill Performance). The initiatives for data preparation
presented herein may be useful to the researchers in this field.

Distinguishing N and P addition from the air using imaging spectroscopy. Alex...
This document discusses using imaging spectroscopy and field studies to distinguish between nitrogen (N) and phosphorus (P) additions from the air. It finds that N addition reduced reflectance by producing more chlorophyll and absorbing more light, while P addition increased reflectance. When a model was trained on treatment classes (control, N, P, N+P) for 75% of plots, it predicted the other 25% of plots with 83% accuracy. Field measurements of resin-available N and P in soil aligned with clustering of tree-top spectra responses to nutrients. This indicates trees can act as remote signals of belowground nutrient availability and function.

Mycorrhizal type and co-limitation of forest productivity. Noah Blumenthal
This study investigated how the two types of mycorrhizal associations in northern hardwood forests (arbuscular mycorrhizal and ectomycorrhizal) influence nutrient limitations and forest productivity. The researchers measured annual stem growth in mature forest stands between 2015-2019. They found that nutrient additions of nitrogen and phosphorus had interactive effects on productivity, suggesting co-limitation, and this effect was stronger for arbuscular mycorrhizal tree species than ectomycorrhizal species. They concluded the greater relative abundance of arbuscular mycorrhizal trees promotes nutrient co-limitation in mature northern hardwood forests.
Grow with the changes: Forest succession and woody debris. Joe Nash
1) The document analyzes data from two studies to quantify stocks of downed dead wood in northern hardwood forest stands of different ages.
2) Thirteen forest stands ages 31-145 years old were inventoried for coarse and fine woody debris using line intersect and nested subplot sampling.
3) The primary objective is to distinguish the characteristics of woody debris corresponding to different successional stages in northern hardwood forests.
Litterfall and soil respiration fluxes in the MELNHE study. Thomas Mann
This document summarizes a study examining how soil respiration and litterfall in northern hardwood forests are controlled by nutrient availability. The study measured soil CO2 fluxes and collected fine litterfall from treatment plots with different nitrogen and phosphorus additions across 13 forest stands from 2008-2019. Preliminary results found that nitrogen addition lowered soil respiration in nitrogen-poor sites from 2011-2013. While apparent trends were observed, the authors note that statistical analysis is still needed and fertilization effects on litterfall may be more complicated. Next steps include further statistical analysis and exploring why nutrient additions did not significantly impact soil respiration rates.
N-P co-limitation in young northern hardwood forest. Tim Fahey
1) The document discusses nitrogen, phosphorus, and fine roots in young northern hardwood stands.
2) It presents the hypothesis that growth of new fine roots in these stands may be co-limited by balanced mineral nutrition of nitrogen and phosphorus.
3) A factorial experiment using ingrowth cores found that fine root growth and biomass increased at the plot level in response to the addition of both nitrogen and phosphorus, but not from the addition of only one nutrient.

This document discusses an experimental study that examined the effects of nutrient amendments on mycorrhizal colonization and root morphology in red maple seedlings. The study predicted that nitrogen amendments would decrease vesicles in roots, phosphorus amendments would increase coil structures, and root morphology would vary depending on mycorrhizal colonization and structures under each treatment type. It then describes the experimental design, data collection process involving root processing and staining, and analysis of mycorrhizal colonization and root morphology.

(1) The MELNHE study examines nutrient co-limitation of forest productivity across 13 forest stands of different ages located in three sites. Fertilization experiments add nitrogen, phosphorus, or both to test for co-limitation.
(2) So far, tree growth has been found to be primarily limited by phosphorus rather than nitrogen or co-limitation.
(3) A new study tested whether root growth is directly limited by nitrogen or phosphorus availability, or responds to aboveground nutrient allocation. Fine root growth responded directly to nitrogen addition but not phosphorus addition, and roots foraged more in phosphorus-rich patches.

This document summarizes a study that examined how the physical, chemical, and metabolic characteristics of sugar maple leaves vary with their depth in the tree crown and with the addition of nutrients. The study found that foliar nitrogen and chlorophyll increased deeper in the crown and with nitrogen addition, while foliar phosphorus increased with phosphorus addition. The study concludes that most leaves are shaded rather than just "sun" or "shade" leaves, and that examining the vertical gradient in a tree crown can help reveal relationships between leaf characteristics and nutrients.
The timing of senescence affects foliar p resorption dan hong
This document discusses a study on the timing of senescence and its effects on foliar phosphorus (P) resorption. The study (1) examined how foliar concentration and resorption of P and other nutrients varied with N, P, and N+P additions and between species, and (2) investigated whether the timing of senescence affected foliar resorption with nutrient additions. Field collections of green leaves and litter were made over multiple dates in the fall. Results showed adding N increased foliar N but decreased foliar P, while adding P increased foliar P. P resorption efficiency was lower under P additions and proceeded over the course of the fall.

In a 3-year pilot study, researchers placed sugar maple wood stakes in forest stands to examine the effects of adding nitrogen, phosphorus, both nutrients, and a control on wood decay. Over 273 stakes were distributed across plots with different nutrient additions or a control at 3 sites. The stakes will be collected and analyzed to determine percent mass loss over the study period, with future analysis of nutrients, soil microbes, and their role in wood decay.

Collecting fungal sporocarps allows researchers to survey the effects of nutrient additions on mycorrhizal fungi fitness over a larger area than soil samples alone. The study aims to determine how ectomycorrhizal sporocarp abundance and fungal community composition vary with nitrogen, phosphorus, and combined nutrient additions and between seasons. Over 4,000 sporocarps from 35 genera and 160 morphospecies were collected and will be identified using genetic techniques to analyze impacts of nutrient manipulations.
Does the fate of n depend on p availability in soil - samuel butler
This document discusses using an N15 experiment to determine if the fate of nitrogen (N) in soil depends on the availability of phosphorus (P). Previous research found that adding phosphorus suppresses resin-available nitrogen in soils. Additional studies showed that trees grew more in response to added phosphorus in mid-aged and old growth forests, but responded more to added nitrogen in younger forests. The proposed experiment would use the N15 isotope to trace nitrogen pathways through soil organic matter, plant roots, the microbial biomass, and mineral soil.

This document summarizes a study estimating belowground carbon allocation in forests by measuring soil respiration and aboveground litter inputs over multiple years. The researchers found that nitrogen decreases soil respiration and likely belowground carbon allocation, while phosphorus decreases leaf litter production. Preliminary results suggest phosphorus may matter more for aboveground growth while nitrogen affects belowground processes to a greater degree.

The document discusses a study examining how nutrient treatments affect germination rates and seedling survival of American beech and sugar maple. The study had three hypotheses: 1) germination and survival of maple would be highest with calcium addition; 2) germination and survival of beech would reflect limitation of nitrogen or phosphorus; and 3) survival may reflect nutritional value of seedlings. Methods involved counting germinants and seedlings in nutrient treatment plots over two years. Results showed beech germination increased with nitrogen and phosphorus addition, while maple decreased. Seedling survival decreased with nitrogen and phosphorus addition but increased with calcium addition, with no difference between nitrogen and phosphorus effects.

Forest inventory crews were analyzed to determine measurement errors in tree diameter. The study found bias may exist due to penalties for observations more than one class off. While measurement error magnitude was identified, the most uncertain measurements may not be the most important to improve. Propagating the errors into forest inventory data product calculations like timber volume and carbon storage will show which measurements are most important to improve.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Climate Change All over the World .pptx
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
Recycling and Disposal on SWM Raymond Einyu pptx
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

- 2. Background • Both N and P may co-limit primary production (Rastetter et al., 2013) • Simultaneous additions of N and P yielded synergistic improvements in primary production (Elser et al., 2007) • Growth responses of separate additions of N and P are indistinguishable (Elser et al., 2007) • Ca additions increase forest evapotranspiration (Green et al., 2013)
- 3. Objectives • Analyze effects of nutrient additions (N, P, N&P, and Ca) by comparing sap flow between treatment plots • Test N&P colimitation within the context of resource optimization theory
- 4. Methods • Ca, N, P, N&P, and control plots in 2 different aged stands over 10 day period • Granier method to estimate sap flow • Baseliner software used to transform data
