More than 5 billion people could suffer water shortages by 2050 due to climate change, increased demand and polluted supplies, according to the UN report on the state of the world’s water. The comprehensive annual study warns of conflict and civilisational threats unless actions are taken to reduce the stress on rivers, lakes, aquifers, wetlands and reservoirs. The report – released in drought-hit Brasília – says positive change is possible, particularly in the key agricultural sector, but only if there is a move towards nature-based solutions that rely more on soil and trees than steel and concrete.
