The Ecological Limits of Hydrologic Alteration (ELOHA) is a new framework offering a flexible, scientifically defensible compromise for broadly assessing environmental flow needs when in-depth studies cannot be performed for all rivers in a region.
The Sustainable Livelihoods Enhancement and Diversification (SLED) approach has been developed by Integrated Marine Management Ltd (IMM) through building on the lessons of past livelihoods research projects as well as worldwide experience in livelihood improvement and participatory development practice.
This report provides an overview of the range of key livelihoods and production systems in the Blue Nile Basin. It is highlighting their relative dependence on, and vulnerability to, water resources and water-related ecosystem services in the catchments. It also elucidates current water and land related policies and institutions.
This report aims to evaluate the impacts of climate change on both hydrologic regimes and water resources of the Upper Blue Nile River Basin in Ethiopia where observed hydrologic data are limited. The downstream countries of the Nile River Basin are sensitive to the variability of runoff from the Ethiopian part of the basin.
This study was driven by two objectives: to develop a framework and methodology for assessing the outcomes of conservation-poverty reduction initiatives and to apply it to such initiatives in wetlands to understand conditions and methods that can support the integration or balancing of ecosystem
This report is a case study on the Krishna River Basin in South India. The basin has witnessed intense water development resulting in downstream environmental degradation. The observed decline in discharge to the ocean sends a strong signal: there is only little scope for further water supply development, and further taming the Krishna waters will exacerbate environmental degradation.
In many cities of developing countries untreated wastewater and polluted water are used for agriculture in urban and peri-urban areas. Though such practices are a threat to the health of users and consumers, they do provide important livelihoods benefits and perishable food to cities. This paper through a cross country analysis of 53 cities in the developing world, provides an understanding of the factors that drive wastewater use.
There are two broad categories of marginal-quality water: wastewater generated by the domestic, commercial, and industrial
sectors; and saline water from agricultural drainage systems, surface runoff, or pumped from overexploited aquifers. Millions of small-scale farmers around the world irrigate with marginal-quality water, often because they have no alternative.
