Half of the world’s population lives in areas that are at least occasionally threatened by water shortages. This is clear from the UN world water report, which was presented in brasilia at the 8. World water forum was presented.
More than 10,000 experts from over 100 countries will take part in the conference in the brazilian capital by friday. The impact of climate change, water supply and management, and the financing of sustainable water management are among the main topics of discussion in brazil.
According to forecasts in the UN world water report, the number of people threatened by water shortages is expected to rise from the current 3.6 billion to 5.7 billion by 2050. According to the international environmental organization WWF, global population growth is one of the main drivers of water scarcity. Climate change exacerbates the problems. "The water crisis is well known, but it is still a blind spot in climate protection," criticized philipp wagnitz, sub-water officer at WWF germany, in the run-up to world water day, which takes place every year on 22. Marz takes place. By 2030, the global water crisis threatens to worsen, he says.
Ulla burchardt, member of the board of the german UNESCO commission, confirmed: "we need new solutions for water management". In the UN report, the focus is therefore on the "nature-based solutions" that had received little attention so far. These forms of water management, inspired and supported by nature, include, for example, the use and creation of wetlands, targeted reforestation and soil cultivation, and the associated groundwater recharge.
The international community must also establish binding rules to reduce water consumption, said andrea muller-frank, a food rights campaigner for "bread for the world. Supplying the local population should take priority over water use for export goods.
"The aim of the forum is to bring scientific and technical knowledge closer to the decision-makers of society," said the chairman of the world water council (WWC), brazilian benedito braga, at the start of the conference. The first world water forum was held in marrakech in 1997.
