The most difficult water resources management challenge in the Ganges Basin is the imbalance between water demand and seasonal availability. More than 80 % of the annual flow in the Ganges River occurs during the 4-month monsoon, resulting in widespread flooding. During the rest of the year, irrigation, navigation, and ecosystems suffer because of water scarcity. Storage of monsoonal flow for utilization during the dry season is one approach to mitigating these problems.

Lima presenta una inequidad en el acceso a los servicios de agua y saneamiento, por ello la modernización del sector apunta a la universalización del servicio. Esta tesis investiga a partir del enfoque de la ecología política y los sistemas socioecológicos los impactos de la política hídrica urbana en la gestión local del agua en las zonas periurbana de Lima, a través de un estudio de caso sobre el acceso al agua y alcantarillado del Asentamiento Humano del Cerro Las Ánimas, en el distrito de Puente Piedra. La investigación se ampara en los pilares de la investigación cualitativa.

Este trabajo tiene por objetivo el análisis de la calidad del agua del arroyo Langueyú para determinar el estado de situación y su relación con la gestión de los recursos hídricos superficiales a nivel local. Se tuvieron en cuenta antecedentes hidrológicos regionales. Se efectuaron recorridos siguiendo el cauce del arroyo desde la cuenca alta, al Sur de la ciudad de Tandil incluyendo sus tributarios Blanco y Del Fuerte, hasta la intersección con la Ruta Provincial Nº 30. Se seleccionaron 9 sitios en los que se realizaron muestreos de calidad de agua en el período 2009-2011.

Water scarcity is one of the greatest challenges of the twenty-first century. Agriculture is both a cause and a casualty of water scarcity. It accounts for an estimated 70 percent of global water withdrawals, with freshwater resources heavily stressed by irrigation and food production. While demand for water for agriculture and other uses are increasing rapidly, climate change also affects fresh water resources negatively both in terms of quantity and quality.

La gestion de l’eau par les petits exploitants agricoles (y compris toutes les formes d’irrigation informelle, privée, eau pour l’élevage, pêche etc.) – la GEA à petite échelle- recèle un potentiel de développement important encore largement inexploité. Le projet financé par le FIDA et mis en oeuvre par la FAO et l’IWMI est une opportunité pour comprendre les conditions de succès pour le développement de toutes les formes informelles de gestion de l’eau en agriculture et pour améliorer l’efficacité et les performances des projets de développement.

When the guns are silenced, those who have survived armed conflict need food, water, shelter, the means to earn a living, and the promise of safety and a return to civil order. Meeting these needs while sustaining peace requires more than simply having governmental structures in place; it requires good governance.

This document provides an overview of how water resource software’s (WRS) are used to manage water resources issues, criteria for WRS selection, and a high level review of WRS currently available that central and state governments of India can use for water management. The water resource issues covered include water allocation and planning, flood management, groundwater management, conjunctive use, water quality, and sediment transport.

With changes in weather patterns and intensifying anthropogenic water use, there is an increasing need for spatio-temporal information on water fluxes and stocks in river basins. The assortment of satellite-derived open-access information sources on rainfall (P) and land use/land cover (LULC) is currently being expanded with the application of actual evapotranspiration (ETact) algorithms on the global scale.

This thesis focused on the use of soil and water conservation (SWC) planning tools to address two ecosystem services (ES’s), erosion control (EC) and dry season baseflow enhancement (BF). The study site was a headwater catchment encompassing Gudo Beret town located in the central sub-humid highlands of Ethiopia.
