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

Tests the hypothesis that, in general, irrigation management transfer has positive impacts on operation performance, managerial accountability, O&M budgeting and expenditures, costs of water to farmers, and agricultural and economic productivity in the Alto Rio Lerma Irrigation District in Mexico. Evaluates the potential of the Mexican IMT process as a model for other countries.

Book Description

There is a significant gap of knowledge about actual results of irrigation management transfer. This includes the questions: Which strategies work? Which don't? and What prerequisites are necesssary to support sustainable local management of irrigation? This report examines the context of transfer, the basic transfer strategy, powers and functions devolved, and the impacts of transfer on irrigation management and irrigated agriculture in three sample irrigation districts of Colombia-the RUT, Rio Recio, and Samaca. data on performance of these schemes were analyzed for 4 or 5 years before and after transfer. Two additional schemes, San Rafael and Maria La Baja, which were transferred just prior to this study, provided a comparison of performance between transferred and nontransferred schemes, form the period of analysis.

Book Description

Watershed analysis provides a framework for ecosystem management, which is currently the best option for conservation and management of natural resources. The current methods of assessing hydrologic impacts of land use transformations at the watershed scale, particularly in the tropics, are impaired by technical, financial, and time constraints. This study provides an alternative approach to ascertain the acutual changes in hydrologic response of a particular watershed to land use transformations made in the past.
