Water

Dr Julian Caldecott is an ecologist with a mission to help reduce and repair the damage that we are doing to the biosphere - the thin skin of life on Earth. He's spent years doing this through projects in tropical countries where the pace of environmental destruction is often fastest. His recent work as a senior consultant to the UN Environment Programme has aimed to restore natural ecosystems so as to reduce disaster risks and increase environmental security in the face of climate change.Julian sees the global water crisis as an outcome of humanity's unbalanced relationship with the biosphere. To correct this, he believes that the most important need is for public understanding of the values, functions and fragilities of nature, upon which effective action can be built. His books, which include Deep Water, Designing Conservation Projects and the World Atlas of Great Apes, aim to promote both understanding and action.
