Download or read book Balancing irrigation and hydropower Case study from Southern Sri Lanka written by Molle, François, Jayakody, Priyantha, Ariyaratne, Ranjith, Somatilake, H. S. and published by IWMI. This book was released on 2005 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report analyzes a case from southern Sri Lanka, where the Samanalawewa dam and the Kaltota Irrigation Scheme (KIS) compete for the water of the Walawe river. At the catchment level, it is shown that dam releases are well attuned to the needs of KIS and to the occurrences of natural runoff, and that little of the dam water is "lost" to the river.

Download or read book An Irrigated Area Map of the World 1999 Derived from Remote Sensing written by Prasad Srinivasa Thenkabail and published by IWMI. This book was released on 2006 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research report presents the results of a global analysis of multi-temporal time series at nominal 10 kilometer pixel resolution. Statistics of irrigation at country level are derived from these maps for different seasons and for the entire year (annualized) for the nominal year of 1999. Three methods of area abstraction are used and compared, and three methods of accuracy assessment are applied. The annualized irrigated areas of the world at the end of the last millennium were about 480 Mha of which there were 263 Mha for season 1, 176 Mha for season 2, and 41 Mha for continuous cropping. Of this, Asia alone accounts for 78 percent (375 Mha) with 59 percent from China and India. The country statistics are compared with FAO country-level statistics (see Annex I). The IWMI GIAM 10 km V2.0 map were tested based on 3 sources of independent data resulting in accuracies between 84 and 91 percent with errors of omission not exceeding 16 percent and errors of commission less than 21 percent. The total area available for irrigation (TAAI; the nearest equivalent to FAO’s equipped area) was 412 Mha.

This book was released on 2006 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report highlights the potentially significant impacts on the hydrologic cycle and the importance of considering secondary effects, particularly with regard to water, resulting from the widespread adoption of global climate change mitigation measures. It is recommended that the implicit hydrologic dimensions of climate change mitigation should be more formally articulated within the international environmental conventions, and recognized within future UNFCCC negotiations on the CDM-AR provisions.

A., Mbilinyi, B. P., Yawson, D. K., Tumbo, S. D. and published by IWMI. This book was released on 2006 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the findings of a study to assess changes to flows into, and downstream of, the Usangu Wetlands, located in the headwaters of the Great Ruaha River, Tanzania. Hydrological data, in conjunction with remote sensing techniques, were used to provide insights into changes that have occurred to the Eastern Wetland. Results indicate that, between 1958 and 2004, inflows to the wetland declined by about 70 percent in the dry season months (July to November) as a consequence of increased human withdrawals, primarily for irrigation.

Download or read book Multiple Uses of Water in Irrigated Areas written by International Water Management Institute and published by IWMI. This book was released on 1999 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is being transferred out of agriculture to meet the growing demand in other areas, often without an agreement of or compensation to farmers with irrigated land and water rights. Furthermore, there is a failure to recognize that irrigation systems supply water not only for the main fields, but also for domestic uses, home gardens, trees and other permanent vegetation, and livestock. Other productive uses include fishing, harvesting of aquatic plants and animals, and a variety of other enterprises such as brick making. In addition, irrigation systems can have a positive or negative effect on wildlife habitats. Thus, the withdrawal of water affects the rural household, rural economy, and the environment in a number of ways. This paper argues that to ensure efficient, equitable, and sustainable water use, to reduce poverty and improve the well-being of the community, irrigation and water resources policies need to take into account all uses and users of water within the irrigation system. The multiple uses of water in the Kirindi Oya irrigation system are examined in this paper. An interdisciplinary group of scientists have investigated a number of areas including water accounting, water quality, household water use, the valuing of water for alternative uses, and the complementarities, competition, and conflicts among uses and users.
