This book was released on 2000 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This survey, presented in English and Spanish, covers 32 countries of Latin America and the Caribbean. The purpose of the survey is to: provide a clear picture of rural water resources management on a country basis with emphasis on irrigation, and featuring major characteristics, trends, constraints and perspectives; help support continental and regional analyses by providing reliable information and to serve as a tool for large scale planning and forecasting. The survey was done by means of: literature review; data collection using a questionnaire; data processing and critical analysis of the information; preparation of a country profile.

Download or read book Field guide to improve crop water productivity in small scale agriculture written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-04-01 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: By 2050, the world’s population will reach 9.1 billion, which requires an increase of food production by 70 percent compared to 2005 (FAO,2018). Nearly all the increase will occur in developing countries, where agriculture plays a major role to provide employment, income and to improve food security. One of the major challenges of increasing food supply is the limited water resources. Agriculture, as the driver of freshwater exploitation has, therefore, to be transformed into more resource efficient production (FAO, 2003). The world’s limited freshwater resources are potentially threatened by the expansion of agriculture. Increasing the potential output per amount of water used is an appropriate practice to improve production efficiency while protecting water resources. Therefore, increasing the productivity of agricultural water use in a sustainable manner is essential to ultimately sustain the social and economic conditions of livelihoods. Crop water productivity has grown into one of the major approaches to cope with water scarcity and advance crop-water relation. The number of conceptual frameworks and implications is ample, but there is always a growing need to review the step-by-step approach beyond. In this Field guide, practical pathways are presented to provide a comprehensive approach for assessing and improving crop water productivity in small-scale agriculture. The Field guide draws lessons learned in three countries (Burkina Faso, Morocco and Uganda) within the framework of FAO project “Strengthening Agricultural Water Efficiency and Productivity at the African and Global Level” funded by Swiss Agency for Development and Cooperation (SDC).

Download or read book The World Bank and Irrigation written by William I. Jones and published by World Bank Publications. This book was released on 1995-01-01 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation This book provides an independent and comprehensive review of World Bank irrigation lending and policy between 1948 and 1993. The Bank's role in irrigation lending has been large--more than $30 billion (in current U.S. dollars) spread over some 600 projects. Only 200 projects have been in place long enough to be assessed. The overall performance record is good, but there is room for improvement.The report finds that there are still pervasive problems in maintenance and operation. Operating chaos prevails in most large canal systems in the humid tropics. In drier areas, drainage is the biggest environmental problem associated with irrigation. The author argues for upgrading existing systems, improving service, involving irrigators, and saving water where it is scarce.

Available in PDF, EPUB and Kindle. Book excerpt: L'estudi de les pràctiques d'hidràulica agrària desenvolupades durant l'Edat Mitjana ha mostrat que no ens trobem davant fenòmens purament «etnogràfics» o solucions universals sense valor històric. En aquesta obra col·lectiva s'ofereixen, d'una banda, treballs representatius de regions on s'inicia l'expansió agrària en el marc de la cristal·lització del sistema feudal (Catalunya Vella, Llenguadoc, Borgonya) i, per un altre, diversos estudis sobre les transformacions produïdes en territori conquistats durant els segles XII (regió de Terol, vall del Segre), XIII (regne de València) i finals del XV (regne de Granada). A través de tots ells s'examina la diversitat de mitjans geogràfics (humits i àrids) on es despleguen tècniques hidràuliques aplicades al cultiu, els prats i la molineria.
