14 A large part of this is indirect use in water-intensive agricultural and industrial production processes of consumer goods, such as fruit, oil seed crops and cotton. Because many of these production chains have been globalised, a persuasive lot of water in developing countries is being used and polluted in order to produce goods destined for consumption in developed countries. 7 Physical and economic scarcity edit water scarcity can result from two mechanisms: Physical water scarcity results from inadequate natural water resources to supply a region's demand, and economic water scarcity results from poor management of the sufficient available water resources. According to the United Nations development Programme, the latter is found more often to be the cause of countries or regions experiencing water scarcity, as most countries or regions have enough water to meet household, industrial, agricultural, and environmental needs, but lack the means. 15 Around one fifth of the world's population currently live in regions affected by Physical water scarcity, where there is inadequate water resources to meet a country's or regional demand, including the water needed to fulfill the demand of ecosystems to function effectively. 15 Arid regions frequently suffer from physical water scarcity. It also occurs where water seems abundant but where resources are over-committed, such as when there is over development of hydraulic infrastructure for irrigation.
The most cost-effective way of decoupling water use from economic growth, according to sanskrit the scientific panel, is for governments to create holistic water management plans that take into account the entire water cycle: from source to distribution, economic use, treatment, recycling, reuse and return. 13 Contents Supply and demand edit Global use of freshwater, 2016 fao data Global water consumption, by region, in billions m3 per year The total amount of easily accessible freshwater on Earth, in the form of surface water ( rivers and lakes ) or groundwater. Of this total amount, 'just'.000 cubic kilometres are being used and reused by humanity. Hence, in theory, there is more than enough freshwater available to meet the demands of the current world population of 7 billion people, and even support population growth to 9 billion or more. Due to the unequal geographical distribution and especially the unequal consumption of water, however, it is a scarce resource in some parts of the world and for some parts of the population. 7 Scarcity as a result of consumption is caused primarily by the extensive use of water in agriculture / livestock breeding and industry. People in developed countries generally use about 10 times more water daily than those in developing countries.
10 11 Climate change, such as altered weather-patterns (including droughts or floods deforestation, increased pollution, green house gases, and wasteful use of water can cause insufficient supply. 12 At the global level and on an annual basis, enough freshwater is available to meet such demand, but spatial and temporal variations of water demand and availability are large, leading to (physical) water scarcity in several parts of the world during specific times. 3 All causes of water scarcity are related to human interference with the water cycle. Scarcity varies over time as a result of natural hydrological variability, but varies even more so as a function of prevailing economic policy, planning and management approaches. Scarcity can be expected to intensify with most forms of economic development, but, if correctly identified, many of its causes can be predicted, avoided or mitigated. 2 Some countries have already proven that decoupling water use from economic growth is possible. For example, in Australia, water consumption declined by 2009 while the economy grew by more than. 13 The International Resource panel of the un states that governments have tended to invest heavily in largely inefficient solutions: mega-projects like dams, canals, aqueducts, pipelines and water reservoirs, which are generally neither environmentally sustainable nor economically viable.

However, due to unequal distribution (exacerbated by climate change ) resulting in some very wet and some very dry geographic locations, plus a sharp rise in global freshwater demand in recent decades driven by industry, humanity is facing a water crisis, with demand expected. 5 7, the essence of global water scarcity is the geographic and temporal mismatch between freshwater demand and availability. The binding increasing world population, improving living standards, changing consumption patterns, and expansion of irrigated agriculture are the main driving forces for the rising global demand for water.
