Evaporation in the reservoirs already exceeds consumption, and global climate change is expected to increase evaporation losses. 2 Groundwater Resources Groundwater is limited in quantity and quality, and is unevenly distributed over the country. Groundwater collects in aquifers, and is abstracted through well ﬁelds (larger villages, mines, power plant and irrigation) and/or individual boreholes (livestock and small villages). , 1991). , 1999). Abstraction is much lower, and therefore country-wide groundwater depletion is unlikely to occur.
There is also a need for further data collection on evaporation, as this data gap becomes more serious with global climatic change. In addition, accounts need to be developed for ephemeral and perennial rivers. 2 Groundwater Groundwater sub-accounts cover the opening stock of aquifers, add the annual recharge and subtract the annual abstraction to lead to the closing stock at the end of the year. The amount of water in an aquifer is not known but also is not necessarily important. What really matters is the part of water resources that can be abstracted and used, preferably in a sustainable manner.
Moreover, water quality is not yet considered, and yet it is increasingly important because of salination and pollution. In this section, the current status of stock accounts is discussed. More work is needed to expand and strengthen stock accounts for water resource management. 3). The sub-account is restricted to reservoirs and does not include lakes and rivers. For reservoirs, annual opening volumes and inﬂow data are recorded for WUC and DWA reservoirs only. The estimated safe yields have been used as opening volume for the reservoirs operated by the Ministry of Agriculture (MoA).
