As droughts fueled by human destruction of the environment are projected to affect three in four people by 2050, investing in sustainable land and water management is essential to reduce their costs, which already exceed $307 billion per year globally.

Drawing on a wealth of evidence and case studies from various countries —including Chile, India, Jordan, Kenya, Spain and Tunisia— this report makes the business case for nature-based solutions to drought — practices that restore ecosystem functions and soil health to enhance water cycling, storage, and supply in support of human wellbeing — for example, reforestation, grazing management, and the management, restoration and conservation of watersheds.
