| Agricultural Water Managed Area, Total |
Thousand hectares |
Sum of total area equipped for irrigation and areas with other forms of agricultural water management (non-equipped flood recession cropping area and non-equipped cultivated wetlands and inland valley bottoms). |
| Area Equipped For Irrigation Full Control, Total |
Thousand hectares |
The sum of surface irrigation, sprinkler irrigation and localized irrigation. |
| Area Equipped For Irrigation, Total |
Thousand hectares |
Area equipped to provide water (via irrigation) to crops. It includes areas equipped for full/partial control irrigation, equipped lowland areas, and areas equipped for spate irrigation. |
| Average Precipitation in Depth |
mm / year |
Long-term average (over space and time) of annual endogenous precipitation (produced in the country) in depth. |
| Average Precipitation in Volume |
109 m3 / year |
Long-term average (over space and time) of annual endogenous precipitation (produced in the country) in volume. |
| Dam Capacity, Total |
km3 |
Total cumulative storage capacity of all dams in each country. The value indicates the sum of the theoretical initial capacities of all dams, which does not change with time. The amount of water stored within any dam is likely less than the capacity due to silting. Data on small dams may not be included, although their aggregate storage capacity is generally not significant. Detailed information on dams can be accessed in regional geo-referenced dam databases on http://www.fao.org/nr/water/aquastat/dams/index.stm. |
| Dependency Ratio |
Percentages |
Indicator expressing the percent of total renewable water resources originating outside the country. This indicator may theoretically vary between 0% and 100%. A country with a dependency ratio equal to 0% does not receive any water from neighbouring countries. A country with a dependency ratio equal to 100% receives all its renewable water from upstream countries, without producing any of its own. This indicator does not consider the possible allocation of water to downstream countries. |
| Groundwater: Total Renewable |
109 m3 / year |
This is the sum of the internal renewable groundwater resources and the total external actual renewable groundwater resources. In general natural and actual external (entering) renewable groundwater resources are considered to be the same.
|
| Surface Water: Total Renewable |
109 m3 / year |
This is the sum of the internal renewable surface water resources and the total external actual renewable surface water resources. |
| Water Resources: Total External Renewable |
109 m3 / year |
Actual External Renewable Water Resources (ERWR_actual): That part of the country's annual renewable water resources that are not generated in the country. It includes inflows from upstream countries (groundwater and surface water), and part of the water of border lakes and/or rivers. Contrary to natural external renewable water resources (i.e. the situation without human influence), ERWR_actual take into account the quantity of flow reserved by upstream (incoming flow) and/or downstream (outflow) countries through formal or informal agreements or treaties, and possible water abstraction occurring in the upstream countries. Therefore, it may vary with time. In extreme cases, it may be negative when the flow reserved to downstream countries is more than the incoming flow. The rules applied for computing ERWR are given in Box 6 (page 15) of FAO Water Report 23. 2003. Review of world water resources by country (http://www.fao.org/ag/agl/aglw/aquastat/reports/index2.stm). |
| Water Resources: Total Internal Renewable |
109 m3 / year |
Internal Renewable Water Resources (IRWR): Long-term average annual flow of rivers and recharge of aquifers generated from endogenous precipitation. Double counting of surface water and groundwater resources is avoided by deducting the overlap from the sum of the surface water and groundwater resources. |
| Water Resources: Total Renewable |
109 m3 / year |
Total Actual Renewable Water Resources (TRWR_actual): The sum of internal renewable water resources (IRWR) and external actual renewable water resources (ERWR_actual). It corresponds to the maximum theoretical yearly amount of water actually available for a country at a given moment. |
| Water Resources: Total Renewable Per Capita |
m3 / inhab / yr |
Total annual actual renewable water resources per inhabitant |
| Water Withdrawal, Agriculture, % of Total |
Percentages |
Agricultural water withdrawal as percentage of total water withdrawal. Agricultural water withdrawal includes annual quantity of water withdrawn for irrigation, livestock and aquaculture purposes. It also includes renewable freshwater resources as well as over-abstraction of renewable groundwater or withdrawal of fossil groundwater, use of agricultural drainage water, (treated) wastewater and desalinated water.
|
| Water Withdrawal, Industrial, % of Total |
Percentages |
Industrial water withdrawal as percentage of total water withdrawal. Annual quantity of water withdrawn for industrial uses includes renewable water resources as well as potential over-abstraction of renewable groundwater or withdrawal of fossil groundwater and potential use of desalinated water or treated wastewater. This sector refers to self-supplied industries not connected to the public distribution network. The ratio between net consumption and withdrawal is estimated at less than 5%. It includes water for the cooling of thermoelectric plants, but it does not include hydropower. |
| Water Withdrawal, Municipal, % of Total |
Percentages |
Municipal water withdrawal as percentage of total water withdrawal. Annual quantity of water withdrawn primarily for the direct use by the population includes renewable freshwater resources as well as potential over-abstraction of renewable groundwater or withdrawal of fossil groundwater and the potential use of desalinated water or treated wastewater. It is usually computed as the total water withdrawn by the public distribution network. It can include that part of the industries, which is connected to the municipal network. The ratio between the net consumption and the water withdrawn can vary from 5 to 15% in urban areas and from 10 to 50% in rural areas.
|
| Water Withdrawal, Per Capita |
m3 / inhab / yr |
Total annual amount of water withdrawn per capita |
| Water Withdrawal, Total |
109 m3 / year |
Annual quantity of water withdrawn for agricultural, industrial and municipal purposes. It includes renewable freshwater resources as well as potential over-abstraction of renewable groundwater or withdrawal of fossil groundwater and potential use of desalinated water or treated wastewater. It does not include in stream uses, which are characterized by a very low net consumption rate, such as recreation, navigation, hydropower, inland capture fisheries, etc. |
