Unprecedented growth in demands for water are threatening all major development goals, warns the latest edition of the UN World Water Development Report, Managing Water under Uncertainty and Risk. It notes that rising food demand, rapid urbanization and climate change are significantly increasing pressure on global water supplies. This complex situation requires a radical rethink of the way water is managed, concludes the Report, to be launched by UNESCO Director-General Irina Bokova and the Chair of UN-Water Michel Jarraud at the World Water Forum in Marseille (France) on 12 March.
