In the world, drinking water is becoming scarcer and arid areas are likely to expand considerably, the United Nations warns in its latest world water report. The Climate change exacerbate the situation and endanger the water supply of billions of people. The authors of the Unesco report say that states must act much more clearly against increasing water scarcity and declining drinking water quality.
"We often talk about water shortages and impending water conflicts, but not enough that water is part of the solution to the climate crisis," said Ulla Burchard, board member of the German Unesco Commission. Effective management of water contributes to climate protection. Wastewater treatment can help reduce greenhouse gases. Agriculture in particular had to be urgently adapted to the challenges of the water and climate crisis.
According to Unesco, 2.2 billion people worldwide have no access to secure Drinking water. More than half of the world's population, 4.2 billion people, would not have safe sanitary facilities. In addition, because of the growing population and economy, worldwide water consumption is six times higher than 100 years ago and increases by 1 percent each year, write the Unesco experts. Climate change is exacerbating this already precarious situation.
