Most people affected by the water crisis live in rural areas, but the cities in which the supply is generally better, the high population growth has increasingly problems to provide a reliable water network. Especially in slum areas, the water supply is usually catastrophic.
The lack of water and sanitation has devastating effects on human health and development as well as on the economy.
More children die from diarrhea than tuberculosis, malaria and HIV / AIDS combined.
The income and standard of living of families who have access to a nearby water source often rises. That is because the women are not spending hours and hours fetching water. They can use the time elsewhere and thus contribute to a higher income. In addition, children go to school more often because they no longer spend so much time collecting water and, in addition, rare diseases such as diarrhea, when clean water is available.
Water consumption in industrialized and emerging countries is very high.
He is particularly strong in the growing economic powers of the South. Increasingly, the lifestyle of the new middle class in economically developing countries is approaching that of the West. Above all, the amount of water required by the high consumption of processed and processed products such as meat, clothing and electrical appliances is significantly higher than the average consumption in the countries of the South. Water consumption is also increasing globally: Excessive use, but also pollution of water, is a real problem. The use of groundwater has at least tripled in the last 50 years and consumption continues to increase by 1 to 2 percent per year. Groundwater resources are not necessarily renewable. Such an enormous exploitation of these resources can lead to their disappearance.
An additional factor that reinforces this trend is population growth: it causes more water to be consumed, more food needed, and more consumed overall. Especially unsustainable irrigation methods in agriculture and high water consumption in industry overuse natural resources.
Agriculture is the sector with the highest water consumption. The problem is that irrigation is often used inefficiently. In order to be able to produce enough food in the future, water resources must be used sparingly and purposefully. This is especially important in order to have sustainable enough water available.
Damage to the ecosystem means that less good quality water is available. Interventions in the ecosystem are carried out through intensive agriculture, urbanization, straightening rivers, damming lakes and feet, cutting down forests and releasing greenhouse gases through various forms of energy production.
The result is steadily increasing water pollution: the quality of the water is dropping.
We need new way of thinking, we need innovative solutions and we need the help of everyone to face water crisis and to improve our way of living.
