Book (stand-alone)Progress on change in water-use efficiency
Global status and acceleration needs for SDG indicator 6.4.1, 2021
2021The global indicator on water-use efficiency tracks to what extent a country’s economic growth is dependent on the use of water resources, and enables policy and decision-makers to target interventions at sectors with high water use and low levels of improved efficiency over time. This indicator addresses the economic component of target 6.4. In this report, you can learn more about the global and country progress on water-use efficiency. More information and methodological guidance can be found at: www.fao.org/sustainable-development-goals/ indicators/641 This report is part of a series that tracks progress towards the various targets set out in SDG 6 using the SDG global indicators.

Book (stand-alone)Efficient agricultural water use and management in paddy fields in Zambia
National outlook
2022Also available in:
No results found.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). -

In view of the projected rise in water demand in 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 Sri Lanka, one-third of the rural population depends on agriculture. Rice is the national staple food which is cultivated twice a year on nearly one million hectares of land under a range of physical and environmental conditions. Currently, about 80 percent of paddy production comes from irrigated agriculture, while 20 percent is by rainfed area. Paddy cultivation is especially water demanding as it needs continues inundation of the field during most of the growing season. Despite being self-sufficient in paddy production, Sri Lanka has relatively low levels of water productivity and water use efficiency. Furthermore, its water and food security is extremely vulnerable to climate change.
