2015 is a pivotal year for water issues globally. To celebrate #WorldWaterDay, UNDP, UN-Water and SIWI - in partnership with One Water project at University of Miami, have produced a film on water and sustainable development. Join in this year’s celebrations, as the world focuses on water and sustainable development and we announce this year’s Stockholm Water Prize Laureate. Previous Laureates, Rita Colwell, Tony Allan and Sunita Narain join UN Deputy Secretary-General, Jan Eliasson to raise the voice of water as ".. a precondition for human existence". #WaterIs development, and it is the theme for the jubilee year of World Water Week in Stockholm.
