What does this informative map cover?
The map includes information about fresh water statistics all over the world - Mapping Fresh Water; Water Withdrawals; Visualising Groundwater Resources; Mapping Irrigation; Securing Safe Drinking Water; Assessing True Water Use.
Freshwater Scarcity: The concept of water stress is relatively new but it is the difficulty of obtaining sources of fresh water for use during a period of time and may result in further depletion and deterioration of available water resources. Water shortages may be caused by climate change, such as altered weather patterns including droughts or floods, increased pollution, and increased human demand and overuse of water.
Freshwater on Earth:Out of all the water available on the Earth, 97 % of water is saline and is in oceans, 3% of water is freshwater available in rivers, streams and glaciers. There is enough freshwater available on the planet for current population of the world but it is distributed unevenly. Freshwater is found in lakes, rivers, soil, snow, groundwater and ice, and is one of the most essential of Earth's resources, for drinking water and agriculture. However, the distribution of freshwater around the planet is changing.
Water Consumption around the world statistics:The data on water consumption in the world is provided by the United Nations (UN, UNESCO, and FAO). Worldwide, agriculture accounts for 70% of all water consumption, compared to 20% for industry and 10% for domestic use. In industrialised nations, however, industries consume more than half of the water available for human use. Belgium, for example, uses 80% of the water available for industry. Freshwater withdrawals have tripled over the last 50 years. Demand for freshwater is increasing by 64 billion cubic meters a year (1 cubic meter = 1,000 litres)
Visualising groundwater resources and mapping irrigation: Groundwater is found almost everywhere, but varies strongly regarding quantity, quality and recharge. The areal distribution of the various hydro-geological types mapped on the groundwater resources map shows that, as a global average, half of the land surface (47 %) of the continents (excluding the Antarctic) is made up of local and shallow aquifers with minor occurrences of groundwater.
World irrigation means the artificial application of water that assists in growing crops, trees and pastures. This happens in three different ways - by letting water flow over the land (surface irrigation), by spraying water water under pressure over the land concerned (sprinkler irrigation), or by bringing it directly to the plant (localised irrigation).
