Toward Sustainable Nitrogen and Carbon Cycling on Diversified Horticulture Fa...National Institute of Food and Agriculture
This study aims to improve understanding of nitrogen and carbon cycling in diversified horticulture systems along an intensification gradient. Two field experiments are measuring soil carbon and nitrogen pools, trace gas fluxes, and leaching losses in different crop rotations. Preliminary energy analysis found cumulative input to output ratios of 10 for an extensive organic system and 48 for a medium-scale organic system, with greenhouse heating and refrigeration being large energy inputs for the latter. Ongoing data collection and modeling will provide insights into nutrient cycling and sustainability across systems. Livelihood and poverty impacts of RWMs: Analysis using Indexing Approach

This document summarizes a study that used the CITYgreen model to assess the ecological and economic benefits of the green spaces on the Stephen F. Austin State University campus. The study found that the university's urban forests provide substantial benefits by reducing stormwater runoff and improving air and water quality. Maintaining the campus's green spaces is important for protecting the environment and reducing infrastructure costs associated with controlling stormwater. The CITYgreen model quantified these benefits in terms of carbon storage, pollutant removal, and avoided costs of stormwater management.

This document summarizes Michigan's Water Withdrawal Assessment Tool, which was developed to assess the potential impacts of large water withdrawals in Michigan. The tool was created in response to 2006 and 2009 legislation requiring withdrawals over 70 gallons per minute to be screened. It uses models of groundwater, surface water, and fish responses to determine if a proposed withdrawal could cause adverse resource impacts. Since 2009, nearly 5,000 registrations have been submitted and screened using this tool, with around 24% requiring more in-depth site reviews. The tool aims to balance water resource protection with minimizing the regulatory burden on applicants.
The impacts of water conservation strategies on water
We assessed impacts on water use achieved by implementation of controlled experiments relating to four
water conservation strategies in four towns within the Ipswich watershed in Massachusetts.

Watershed assessment modelling
The document summarizes a watershed assessment of the Tenmile Watershed that was selected as a pilot project to improve water quality. The assessment identified critical sources of pollution, evaluated the effectiveness of conservation practices, and informed outreach efforts to landowners. Modeling identified areas with the highest potential to contribute phosphorus, nitrogen, sediments, and pathogens to the watershed. Cover crops were shown to reduce phosphorus and nitrogen levels. A survey found the greatest threats to be agriculture and development, while funding and lack of information were barriers to adopting practices. Outreach is now targeted based on the watershed assessment results.

Policy Brief 11
This document summarizes a study on the impacts of climate change and land use change on water resources and food security in the Pangani River Basin in Tanzania. Researchers found that between 1987 and 2010, land used for cultivation increased while forest and grassland decreased. Hydrological modeling showed this decreased average river flows. Climate change is also projected to decrease stream flows by 5.3% by 2060, increasing unmet water demands. Water scarcity threatens livelihoods and food security in the basin. The study recommends integrated water resource management, efficient irrigation, and capacity building to help adapt to these challenges.

This document discusses a workshop on shallow groundwater utilization in the Volta Basin. It will examine current irrigation practices and recommend more efficient alternatives using shallow groundwater. Previous research identified areas with shallow groundwater reserves but only 5% is currently extracted. The project will explore improved groundwater irrigation methods and applicable areas. It will evaluate technologies like well designs and pumps. Research questions focus on usability, efficiency, and sustainability of groundwater extraction. Activities include assessing current performance, identifying gaps, monitoring water levels, and evaluating alternative energy sources for irrigation.
SASBE conference 2009, Delft
This document discusses expanding the concept of exergy, which represents the unused fraction of energy, to urban water cycle management. It aims to optimize the integrated management of urban energy and water resources through a shared framework that models their dynamics and complexity at varying usage levels. The author proposes that energy and water cycles in cities can be better understood and planned by comparing them on multiple scales and coupling supply and demand to minimize unused fractions through cascading and prioritizing local resources. An integrated approach considering both quantities and qualities spatially and temporally could guide more strategic planning of urban flows.

Soil hydrophobicity impacts agriculture by affecting water retention and flow. Hyperspectral remote sensing shows potential for identifying and mapping soil hydrophobicity at large scales. The researchers developed methods for rapid field hyperspectral sensing and used the data to build predictive models of hydrophobicity. They also developed aerial-ground sensing networks and physics-based models to better understand hydrophobicity effects on soil properties and water flow patterns at different scales. Current work involves UAV hyperspectral imaging and field tests in the US and Israel to further develop methods for large-scale hydrophobicity assessment.Integrated Plan for Drought Preparedness and Mitigation, and Water Conservati...

This study aims to develop guidelines for drought preparedness and mitigation in the Skunk Creek Watershed in South Dakota. Researchers used the SWAT model to simulate water levels and identify drought triggers. Sensors were installed to monitor soil moisture, temperature, and tension. The SWAT model was calibrated and validated against historical stream discharge data. Preliminary results found the model simulated discharge reasonably well. Future work will use the model to estimate climate change impacts on water balance and identify drought-prone areas to inform water management practices and conservation. The overall goal is to develop a watershed-based plan to ameliorate impacts of drought on agriculture.MOSAICC – The Forestry component

Landscape conservation cooperatives
This document discusses efforts to integrate conservation across the Mississippi River Basin through Landscape Conservation Cooperatives (LCCs). It describes how the LCCs are working with dozens of agencies and organizations across seven states to leverage wildlife conservation to also benefit water quality, agriculture, and other sectors. The goal is to provide tools to target conservation investments that benefit both the environment and local economies. Examples of high-impact conservation practices are described, and spatial analysis is being used to identify key locations for implementing practices to maximize benefits. Local pilot projects in Indiana aim to demonstrate wildlife, water quality, and agricultural benefits at a smaller scale.
Landscape effects watershed anache
This study evaluated the correlation between physical features of a watershed and its geological, geomorphological, and pedological aspects. The study area was the Guariroba stream subwatershed in Brazil. Data on the watershed's physical characteristics, geology, geomorphology, and pedology were collected. Correlations between spatial data and physical features were analyzed. Few strong correlations between physical features and geology or geomorphology were found. However, several physical features like area, perimeter, elevation, drainage density, and overland flow length showed strong correlations with types of soils in the watershed, particularly entisols occurrence and sandy soils with or without organic layers. The physical features of the watershed were found to be correlated

Sharpley - The Importance of Monitoring to Determine Farm ImpactsSoil and Water Conservation Society
The document discusses water quality monitoring of the C&H Hog Farm located near the Buffalo National River in Arkansas. Key findings from monitoring the farm's impact on nutrient, sediment, and bacteria levels in nearby Big Creek and springs include: 1) Nitrate-N and phosphorus levels were similar or slightly lower downstream than upstream; 2) E. coli levels were highly variable between sites and storms; and 3) No consistent trends have emerged so far to indicate water quality issues. The document emphasizes that monitoring must continue to provide transparency and data for permitting agencies, while acknowledging extreme views on either side may not be swayed.Identifying priority management zones for bmp implementation in impaired
Identifying priority management zones for bmp implementation in impairedSoil and Water Conservation Society
This document describes a method for identifying Priority Management Zones (PMZs) for implementing Best Management Practices (BMPs) in watersheds. It involves using terrain analysis with GIS to identify Critical Source Areas (CSAs), which are locations that contribute high pollutant loads and connect to surface waters. Field verification is then used to ground-truth the CSAs. Case studies integrate the terrain analysis and field data with watershed modeling to further target and prioritize areas for BMP implementation. The goal is to develop a repeatable process to efficiently focus conservation efforts in the places that will have the biggest water quality impact.Swcs grand challenge gulf hypoxia g white
This document outlines a precision conservation initiative across the Mississippi River Basin to address issues impacting wildlife, water quality, and agriculture from the prairies to the Gulf of Mexico. It proposes integrating the efforts of various agencies and organizations using spatial analysis and targeted practices. The initiative would identify 12 high-impact conservation practices and focus on 6 Midwest watersheds. It would develop pilot projects in the Lower Wabash Floodplain and Decatur County, Indiana to test the approach at smaller scales. Applied research on human dimensions and integrated performance metrics is also proposed. The overall goal is to leverage conservation efforts across sectors for multiple benefits.
Evaluating nitrogen export
1) The study evaluated nitrogen export from a 389-ha tile drained watershed in central Ohio over multiple years.
2) Tile drains contributed 56% of the watershed's monthly discharge and 73% of its nitrate export.
3) Nitrate concentrations in tile drainage flows were highest in winter and spring and when corn was planted. Tile drainage plays a major role in nitrogen loss from the watershed.

New swat tile drain equations
The document describes modifications made to tile drain equations in the Soil and Water Assessment Tool (SWAT) model. It details the addition of two new parameters (Kirkham g and HDRAIN) based on sensitivity analysis. Calibration and validation of the revised SWAT model at an agricultural site in Minnesota from 1983-1996 showed good performance. Sensitivity analyses found that decreasing drain depth and spacing or nitrogen application rates reduced tile flow and nitrate losses the most. Long-term analysis from 1915-1996 indicated precipitation significantly impacted nitrate losses. The modifications allow SWAT to better simulate tile drainage impacts.

Historical Analysis of Agroenvironmental Conditions
This document summarizes a study analyzing historical agroenvironmental conditions in the Lower Mississippi River Basin. The study examined long-term trends in natural resources and the environmental impacts of agriculture using data on land use, precipitation, hydrology, and water quality. The researchers found evidence that intensive groundwater irrigation in agricultural watersheds has altered surface water flows, reducing base flows and increasing low flow events, compared to non-agricultural watersheds. While more analysis is needed, the results suggest tradeoffs between agricultural productivity and hydrologic alteration may need to be considered for sustainable management in the region.

Development of a Global Hydrological Model for Integrated Assessment Modeling
1) The document discusses the development of a global hydrological model (IGHM) to simulate the global water cycle and quantify water availability under climate change for integrated assessment modeling of global food and water systems.
2) IGHM simulates the natural hydrological cycle on a 0.5 degree grid at monthly time steps and has been calibrated and validated against observed runoff data with good results.
3) Model simulations of historical and future climate scenarios show changes in runoff patterns and amounts at the global scale that could impact water resources availability.
Guillaume Gruere, OECD
This document summarizes findings from an OECD study on groundwater use policies in agriculture. It finds that groundwater irrigation accounts for 33% of total irrigated land and 56% of withdrawals in OECD countries. Intensive pumping can cause negative externalities like stream depletion, salinity, and land subsidence. Countries take diverse regulatory approaches from direct controls to economic instruments to collective management. Regions with less management experience higher groundwater use and stress. The study recommends a "tripod approach" for intensive use regions, involving entitlement systems, economic instruments, and collective management to move towards sustainability.

Using Novel Geospatial Tools and Approaches for Identifying Critical Nutrient...Soil and Water Conservation Society
This presentation demonstrates how geospatial tools like high resolution digital elevation models and GIS techniques can be used to identify critical nutrient source areas and target agricultural best management practices. It describes a project in the Grand River watershed that developed a DEM and used terrain analysis and the RUSLE model to map priority areas for gully and sheet erosion. These maps can help extension programs better target outreach and financial incentives to farmers in high risk locations. Initial results show this approach increased requests for technical assistance and requests for mapping in new areas. Future applications include identifying priority subwatersheds and connecting issues to appropriate BMPs.Shoreline Owners Perception study-Sebago Lake

The document summarizes a meta-analysis that compared the nitrate removal performance of different substrates used in denitrifying bioreactors. It found that wood media had the highest nitrate removal rate (NRR) and percentage (NRE), followed by mulch media, nutshell-based media, and inorganic media. However, when considering cost-effectiveness, woodchip and corn cob were the most economical natural organic carbon substrates. Overall, the analysis suggests that mulch media is the optimal material for nitrate removal due to its low cost and potential to overcome deficiencies in other media types.

This document summarizes a study that evaluated a procedure for prioritizing maintenance of agricultural drainage ditches. The study measured the critical shear stress of soils using a cohesive strength meter to assess their susceptibility to erosion. Soils with higher root densities and those treated with mixed lime showed higher critical shear stresses, meaning they were less susceptible to erosion. Measurements of pressure on the soil surface during testing were mostly lower than estimates from other studies. The procedure effectively identified the relative erosion resistance of different soils, aiding prioritization of drainage ditch maintenance needs.

The document summarizes research on managing drainage water in the Holland Marsh region of Ontario to improve water quality and agricultural productivity. Key points:
- The Holland Marsh is an important vegetable growing region on organic soils, but drainage into Lake Simcoe contributes excess nutrients.
- A study evaluated controlling water tables with controlled drainage to reduce pumping and nutrient loads in drainage water. Modeling and monitoring found it effective for water conservation but more limited for nutrient reductions.
- Soil phosphorus pools, particularly aluminum and iron-bound phosphorus, were found to influence phosphorus levels in drainage water more than drainage management alone. Fertilizer applications exceeded crop needs, accumulating legacy phosphorus in soils over time.

This document discusses how the choice of pipe material influences drain spacing and system cost. It finds that pipe with more rows of perforations, such as an 8-row regular perforated pipe, has a higher effective radius than a 4-row pipe, allowing for wider drain spacing. Experiments show that a sock-wrapped pipe has the highest drain inflow of the pipes tested, both with and without drain sedimentation present. The key takeaways are that the number of perforation rows and slot length most impact effective radius and drain flow, and a sock-wrapped pipe performs best in terms of drain inflow and spacing.

They allow for channel vegetation, improve sediment settling, and provide water quality benefits. Challenges include obtaining land access, communication with landowners, permitting, and planting/erosion control. Case studies of implemented two-stage ditch projects in Lucas County demonstrate post-construction conditions and results, including improved drainage and yields for agriculture.
September 1 - 0130 - Johnathan Witter
This document summarizes research on conservation channel design and sediment capture in two-stage ditches. It finds that self-forming channels accumulated more sediment, carbon, nitrogen, and phosphorus over time compared to traditional ditches. Sediment analysis showed higher nutrient levels than surrounding soils. A case study site captured over 500 kg of phosphorus over 9 years that could be harvested and reused as fertilizer, offsetting nutrient costs for farmers. The document concludes sediment trapping in two-stage ditches can improve water quality while providing a locally sourced, cost-effective fertilizer resource.

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.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
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.

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.

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.

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

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

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.
