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.

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.

An increasing number of regions in the world are frequently facing water shortage, and water demand is likely to grow in the next 20-30 years due to intensified agriculture, population growth, urbanization and climate change. Future demand of water by all sectors will, thus, require as much as 25 to 40 percent of water to be re-allocated from lower to higher productivity and employment-oriented activities, particularly in water stressed regions. As such, these reallocations are likely to come from agriculture due to its high share of water use. In view of the projected rise in water demand in both agriculture and non-agricultural sectors, appropriate actions that increase water use efficiency especially in irrigation are crucial to sustainably enhance agricultural production and productivity. In Zambia, rice is one of the most important cereal food and is at the centre of major socioeconomic activity for a large share of rural population. Paddy field system are especially water demanding as it needs continues inundation of the field during most of the growing season. In Zambia, there is no controlled infrastructure for paddy irrigation and nearly all of the rice is grown under paddy field system in the country rainfed lowlands. 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 the project “Efficient Agricultural Water Use and Management Enhancement in Paddy Fields”, funded by the Japan Ministry of Agriculture, Forestry and Fisheries (MAFF).

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.

The Indus and Ganges River Basin, being the most populous in the world, is under extreme pressure to sustain food security. Production resources including water are being exploited to various levels from underdevelopment to heavy overexploitation. This report provides a bird’s eye view of the basin and focuses on the nexus between agricultural production and water consumption, making it possible to pinpoint the areas with high/low water productivity and identify the factors behind this, which helps to promote informed decision making in light of environmental sustainability.

*First title in a major new series *Addresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental security *Draws from scientists having a multitude of disciplines to approach this important problem In a large number of developing countries, policy makers and researchers are increasingly aware of the conflicting demands on water, and look at agriculture to be more effective in its use of water. Focusing on both irrigated and rain-fed agriculture, this book gives a state of the art review of the limits and opportunities for improving water productivity in crop production. It demonstrates how efficiency of water use can be enhanced to maximize yields. The book represents the first in a new series of volumes resulting from the Comprehensive Assessment of Water Management in Agriculture, a research program conducted by the CGIAR's Future Harvest Centres, the Food and Agriculture Organization of the United Nations and partners worldwide. It will be of significant interest to those working in areas of soil and crop science, water management, irrigation, and development studies.
