 We are today facing some climatic variability that affects the populations around the world. We need to increase our resilience to climate change, providing water security for all. So the idea is to look at what water security means to present the concept, to show that the less developed countries are the most in need to increase their water security. The idea behind the World Water Forum is to make sure that the political and the professional communities get together. The idea of the World Water Forum is to make the link between those that make the decisions that put in practice the policies and those that think about the policies, those professionals that structure these policies that they can talk together and then make a change, a real change, that is the professionals interacting with the politicians, the decision makers, in order for the water agenda to move forward in the world.
