The Challenge Program on Water and Food undertakes research to maximize water productivity in several of the world’s major river basins. The research must be underpinned by information on how much water there is in a basin, where it goes and how it is used. There should, furthermore, be an understanding of future constraints (such as the impact of climate change), opportunities (such as increased diversions for irrigation), and trade-offs (such as changed land use improving dryland productivity but leaving less water for downstream use). We describe the underlying concepts of water use accounts that provide monthly estimates of major water uses in a river basin. We have used them for historical estimates, and they can also be used for prediction. Starting with rainfall (and in some basins snowfall), the accounts track the partitioning of water into runoff, and evapotranspiration by dryland vegetation. The runoff is tracked as it becomes flow down the rivers, with losses (such as evaporation and seepage) and gains (such as tributary inflows), storages in lakes and reservoirs, diversion for irrigation or other purposes, floods in lowland floodplains, and finally discharges to the sea. The account estimates the water use by the major irrigation industries and other uses. The account helps develop understanding of the water uses in a basin, and the likely consequences of large changes, such as climate change, land-use change, increased diversions and irrigation water use, and changed storages. The water use accounts are developed as Excel spreadsheets. They are a tool for integrated water-resources management, and provide a sound basis for integrating hydrology, environment, social and economic issues, and policy and institutional issues in a river basin.

This paper applies the principles of water-use accounts, developed in the first of the series, to the Mekong River basin in Southeast Asia. The Mekong Basin covers six countries, the River rises in China, but there are substantial downstream tributaries from Thailand, Laos, Cambodia, and Vietnam, and from a small area in Myanmar. A unique feature is the reverse flow from the Mekong to the Tonle Sap via the Tonle Sap River at the height of the wet season flow and its ebb as the river levels fall. Net runoff is about 37% of total precipitation. Forest and woodland cover 43% of the basin and use about 33% of the precipitation. Grassland covers much of the upper part of the Basin, consuming about 6% of the precipitation. Irrigated agriculture covers just 6% of the Basin and uses about 6% of the water (excluding runoff). Climate change, using an assumed change in rainfall distribution, shows that with the expected shorter and more intense rainy season, and longer and more intense dry season, both floods and seasonal water shortages may be exacerbated.

This paper applies the principles of water-use accounts, developed in the first of the series, to the Nile River basin in Northeast Africa. The Nile and its tributaries flow though nine countries. The White Nile flows though Uganda, Sudan, and Egypt. The Blue Nile starts in Ethiopia. Zaire, Kenya, Tanzanian, Rwanda, and Burundi all have tributaries, which flow into the Nile or into Lake Victoria. Unique features are Lake Victoria and the Sudd wetland where White Nile loses about half of its flow by evaporation, and the Aswan Dam which controls flow in the lower part of the Basin and also is where 15-20% of the flow is lost to seepage and further evaporation. Net runoff is minimal in many catchments of the Nile Basin, comprising 6% or less of the water available in 16 catchments of the Basin. In the remaining catchments, net runoff ranges from 9% (Panyango) to 34% (Gambella) of the available water. Water use by grassland is important in all catchments where it comprises 13 to 76% of the water available, except in the Lower Basin, where it comprises only 7% or less of the available water. In upstream catchments, woodlands and forests are the major components of land-use, while in the Lower Basin catchments barren and sparsely vegetated land is the main land-use class. Rainfed agriculture is the most important water use by volume in only four catchments, Kessie, Paraa, Panyango, and the Sennar Dam where it comprises 24%, 27%, 30%, and 38% of the available water. Nevertheless, it is a relatively important use of water in many of the catchments, using 10% or more of the available water in 14 catchments of the Basin. Irrigated agriculture is the least use of water by volume, using 4% or less of the available water in all catchments except the d/s of Jebel Aulia, the Sennar Dam, Thamaniyat, Hudeiba, Atbara, Naga Hammadi, El Ekhsase, and Estuary catchments. It is, however, the most important water use in the Estuary catchment, using 90% of the available water. The effect of climate change on rainfall in the Nile Basin is very uncertain, but temperature is expected increase by about 2°C by mid-century. To show the possible effects, we increased potential evapotranspiration by 5%, and left rainfall unchanged. The flow at Aswan Dam declines by about 6%, and irrigated crop water use in the El-Ekhsase region increases by about 2%.

This paper applies the principals of water-use accounts developed in the first of the series, to the Volta River Basin in West Africa. The Volta Basin covers six countries, with 85% of its area in Ghana and Burkina Faso. The three main tributaries, the Black Volta, the White Volta, and the Oti Rivers, all rise in Burkina Faso. The major feature of the Basin is the Akosombo Dam, which creates the world's largest man made lake. Precipitation increases strongly from the dry upper reaches in the north of the Basin towards the south, where the river discharges into the Gulf of Benin.
Runoff in three tributaries increases from 2-7% in the drier north to 12-26% in the higher-rainfall south. Grassland is the dominant land use throughout Basin ranging from 76% of the Delta catchment in the south to 98% of the Arly catchment with corresponding water use of 55% and 92% of the water used in each. Water used by rainfed agriculture ranges from 1 to 18% of the water available. Water used by irrigated agriculture is negligible.
Climate change, if it is assumed to increase annual precipitation by 7.5% will increase the frequency of spill from the Akosombo Dam and make more water available for hydropower generation. Increasing irrigation in the basins of all three tributaries to about one-third of the land identified by FAO as potentially irrigable gives lower flows and storage in the Dam.

This paper applies the principles of water-use accounts, developed in the first of the series, to the Ganges River Basin in South Asia. The Ganges Basin covers six countries, the River rises in the western Himalayas in the Uttarakhand state of India. A unique feature is the strong seasonal variation in both precipitation and potential evaporation. The water related issues of the basin are both due to high and low flow.
Net runoff is about 37% of total precipitation. Rainfed agriculture covers 52% of the basin and use about 32% of the precipitation. Grassland covers much of the upper part of the Basin, consuming about 9% of the precipitation. Irrigated agriculture covers 25% of the Basin and uses about 18% of the water.
Changing irrigation efficiency from the currently assumed 40% to 60% and increasing the irrigated area by 10% has relatively little impact on water availability overall, since the water thus made available can be consumed downstream.

This paper applies the principles of water-use accounts, developed in the first of the series, to the Limpopo River Basin in Southern Africa. The Limpopo Basin rises in South Africa and flows northwest along the border with Botswana and Zimbabwe before crossing Mozambique to enter the Indian Ocean. Rainfall in the basin varies between 200 and 1500 mm, with much of the northern and western parts receiving less than 500 mm. Rainfall is strongly seasonal, with a short rainy season leading to negligible river flows in the dry season.
Net runoff from the basin is about 2% of the water received as precipitation. Grassland covers 57% of the Basin and uses about 53% of the available water. Rain fed agriculture covers 40% of the Basin and uses 40% of the available water. The area of irrigated agriculture is small and uses less than 1% of the available water. Although industrial water use in the Upper Olifants River is important locally, it accounts for only 0.3% of the total available water.
Climate change, using an assumed decrease of 7.5% in precipitation overall would reduce discharge of the basin by 25%. A proposed dam in Mozambique to irrigate 1000 km would likely reduce downstream flows in normal years, but would probably not prevent floods like those of 2000.

This paper applies the principles of water-use accounts, developed in the first of the series, to the Indus River basin in South Asia. The Indus Basin covers 3 countries, rises in the Tibetan plateau in the vicinity of Lake Mansarovar in China. Irrigated agriculture in the Basin is extensive with the construction of dams, barrages, and link canals to distribute water, with modern engineering to support irrigation starting as early as the mid 1800s.
Net runoff is about 10% of total precipitation. Irrigated agriculture covers 20% of the basin and use about 31% of the precipitation. Grassland is the most extensive vegetation, covering 45% of the Basin, consuming about 36% of the precipitation. Rainfed agriculture covers 14% of the Basin and uses about 15% of the water.
Changing irrigation efficiency from the currently assumed 40% to 60% and increasing the irrigated area by 10% has relatively little impact on water availability overall, since the water thus made available can be consumed downstream.
