Book excerpt: Global water demand is likely to grow in the next 20 to 30 years due to agriculture intensification, population growth, urbanization, and climate change. In Sri Lanka, one-third of the rural population depends on agriculture. Rice is the national staple food which is cultivated twice a year on more than half a million hectares of land under a range of physical and environmental conditions. Despite being self-sufficient in rice production, Sri Lanka has low levels of water productivity and water use efficiency in paddies. Furthermore, its water and food security is extremely vulnerable to climate change. The Food and Agriculture Organization of the United Nations (FAO) has been active to increase the understanding of the status of water use efficiency and water productivity in Sri Lanka through the project “Efficient Agricultural Water Use and Management Enhancement in Paddy Fields”, funded by the Japanese Ministry of Agriculture, Forestry and Fisheries (MAFF). The project objective is to identify limits and potentials of paddy rice production at national level. The project findings presented in this report are a basis for assisting the country with the evaluation of the status of water use efficiency and water productivity of paddy fields, providing technical and policy support to enhance water resources management in Sri Lanka.

This book was released on 2022-08-27 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: In view of the projected world water demand, increased water use efficiency in irrigation is crucial to sustainably increase agricultural productivity. Paddy field systems are especially water demanding, though products such as rice is not only a staple food, but also constitutes a major social and economic activity providing public goods and is a key source of employment and income for the rural population in Zambia. The Food and Agriculture Organization of the United Nations (FAO) has been active to increase the understanding of the status of water use efficiency and water productivity in Zambia through implementing the project “Efficient Agricultural Water Use and Management Enhancement in Paddy Fields”, funded by the Japan Ministry of Agriculture, Forestry and Fisheries (MAFF). The project objective is to identify limits and potentials of paddy rice production at national level. The project findings presented in this report is a basis for assisting the country with the evaluation of the status of water use efficiency and water productivity of paddy fields, providing technical and policy support to enhance water resources management in Zambia. This report will help increasing the knowledge and building capacities of technical experts in relevant institutions, ministries and universities in Zambia. Its analysis of best practices will assist in determining the needs and existing gaps and what options are available to fill these gaps. Furthermore, the policy action matrix developed and the investment portfolio compiled will support the development of future financial plans in the country.

Book excerpt: Today, there is an increasing worldwide interest in assessing the potential for maintaining or increasing rice yields by reducing or eliminating the use of chemicals and by decreasing irrigation requirements. The System of Rice Intensification (SRI) first developed in Madagascar and now being tested in many countries, is an example of such an approach. The system is based largely on organic farming principles and additional requirements for spacing and the transplanting of seedlings.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, we have witnessed a growing scarcity of and competition for water around the world. As the demand for water for domestic, municipal, industrial, and environmental purposes rises in the future, less water will be available for agriculture. But the potentials for new water resource development projects and expanding irrigated area are limited. We must therefore find ways to increase the productivity of water used for irrigation. This paper reviews the literature on irrigation efficiency and on the potential for increasing the productivity of water in rice-based systems. It stresses the continuing confusion over the concepts of irrigation efficiency and water productivity. It identifies the reasons for the wide gap between water requirement and actual water input (both irrigation diversions and rainfall) in irrigated rice production systems and discusses potential opportunities for increasing water productivity both on-farm and at the system level. Based on the reported low farm and system level irrigation efficiencies, the potentials for water savings in rice production appear to be very large. But we do not know the degree to which various farm and system interventions will lead to sustainable water savings in the water basin until we can quantify the downstream impact of the interventions. Studies on the economic benefits and costs, and environmental aspects of alternative interventions are also lacking. This paper emphasizes the need to measure the productivity of water at farm, system, and basin levels, and to understand how the productivity at one level relates to the productivity at another. Without water balance studies to measure productivity at these different scales, it is not possible to identify the potential economic benefits of alternative interventions and the most appropriate strategies for increasing irrigation water p productivity in rice-based systems.

Book excerpt: In December 2002, a group of specialists on water resources from the United States and Iran met in Tunis, Tunisia, for an interacademy workshop on water resources management, conservation, and recycling. This was the fourth interacademy workshop on a variety of topics held in 2002, the first year of such workshops. Tunis was selected as the location for the workshop because the Tunisian experience in addressing water conservation issues was of interest to the participants from both the United States and Iran. This report includes the agenda for the workshop, all of the papers that were presented, and the list of site visits.
