Book Description

In this study, satellite remote sensing and geographic information system (GIS) techniques were used to analyze the agricultural performance and sustainability of the Bhakra Irrigation System in India. The results demonstrate the synergy possible from applying satellite remote sensing and GIS to evaluate trends in rising water tables and salinity, which are two important threats to the sustainability of irrigation systems, and the cost-effectiveness of these techniques as diagnostic tools for irrigation system improvement.

Book Description

Viewed by some as symbols of progress and by others as inherently flawed, large dams remain one of the most contentious development issues on Earth. Building on the work of the now defunct World Commission on Dams, Thayer Scudder wades into the debate with unprecedented authority. Employing the Commission's Seven Strategic priorities, Scudder charts the 'middle way' forward by examining the impacts of large dams on ecosystems, societies and political economies. He also analyses the structure of the decision-making process for water resource development and tackles the highly contentious issue of dam-induced resettlement, illuminated by a statistical analysis of 50 cases.

Book Description

The Atankwidi Catchment, which lies in the White Volta Basin in West Africa, is intensively cultivated by locals for economic gains. During dry seasons, farmers irrigate their crops, chiefly tomatoes, using shallow groundwater harvested from shallow ponds they dig using simple tools like an axe, hoe, bucket and bowls. Recent expansion in cultivated areas has brought to the fore the need to estimate the volume of shallow groundwater stored in the catchment’s underlying aquifer and to what extent it can sustain the incremental growth in irrigated areas.

Book Description

Discusses and illustrates concepts for identifying ways of improving productivity of water within basins. The results of applying a water accounting procedure to four sub-basins in South Asia (Bhakra in India; Chishtian in Pakistan; Huruluwewa in nothern Sri Lanka; and Kirindi Oya in southern Sri Lanka) are presented. The methodology used identifies the quantities and productivity of various uses of water within a basin. This information is then used to identify the water-saving potential, and the means of improving the productivity of the managed supplies.

Book Description

The degradation of land and water resources resulting primarily from agricultural activities has had enormous impact on human society. In order to alleviate this problem an advanced understanding of the state of our resources and the process of degradation is needed. Conserving Land, Protecting Water includes an overview of existing literature focusing on global patterns of land and water degradation and discussions of new insights drawn from successful case studies on reversing soil and water degradation and their impact on food and environmental security.
