Livestock is an integral part of the agricultural system in sub-Saharan Africa, serving as a food source, income, fertilizer, and power for farming transportation. However, productivity livestock has been hampered due to lack sufficient quantity quality feed. This study evaluates gaps constraints fodder nutritional potential feed using small-scale irrigation (SSI). The comprised 30 randomly sel...

Ecosystem-based adaptation (EbA) can potentially mitigate watershed degradation problems. In this study, various EbA measures were evaluated using a bio-physical model called the Soil and Water Assessment Tool (SWAT), in small, forested named Hui Ta Poe, northeastern region of Thailand. The developed was first used to investigate effect degraded watersheds due land-use changes on sediment yield...

Multiple rivers flowing into the same bay can be correlated in water quality management and together determine environmental status of bay. Nonpoint source pollution for multi-watershed aiming to alleviate contamination as well yield considerable economic benefits under additional challenges. In this study, a Bayesian simulation-based effluent trading designing model (BS-METM) is established no...

The study was taken in Srinivaspura taluk, Kolar district of Karnataka to analyse the economic benefits derived by watershed beneficiaries Yeldur nala sub project implemented under Pradhan Mantri Krishi Sinchayi Yojana-Watershed Development (PMKSY-WD). Primary data research gathered from randomly selected 60 farmers area which includes 30 and non-beneficiaries. Data collected analysed using Sim...

Abstract Background Assessing soil erosion, sediment yield and retention capacity of watersheds is one the under-researched areas in developing countries like Lake Hawassa watershed. The study examined erosion their environmental implications quantification mapping were carried out using Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model. Data such as Land Use Cover (LULC), Digita...

We study the problem of automatically identifying watershed boundaries from digital elevation data. Nelson et al. have a vector-based algorithm to solve this problem, but their approach cannot guarantee that each watershed is a single polygon because of the modeling assumptions. We propose a vector-based algorithm that is provably consistent with its modeling assumptions and that guarantees one...

A framework is built, wherein hydrological/water quality model is used to measure watershed sustainability. For this framework, watershed sustainability has been defined and quantified by defining social, environmental and biodiversity indicators. By providing weightage to these indicators, a “River Basin Sustainability Index” is built. The watershed sustainability is then calculated based on t...
