Book excerpt: This unique, engaging, and highly authoritative volume enlightens readers on changes needed in the way society accesses, provides, and uses water. It further shines a light on changes needed in the way we use food, energy, and other goods and services in relation to water, and offers projections and recommendations, up to 2050, that apply to water access challenges facing the poor and the common misuse of water in industry, agriculture, and municipalities. Written by an unparalleled slate of experts convened by the Calouste Gulbenkian Foundation, the book takes on one of the most critical issues on the planet today. In a frank yet optimistic assessment of major developmental challenges, but also opportunities, facing future generations, the author elucidates linkages between water and a range of other drivers from various disciplinary and stakeholder perspectives. Ultimately portraying the belief that Humanity can harness its visionary abilities, technologies, and economic resources for increased wellbeing and sound stewardship of resources, the book presents an optimistic statement stressing actions scientists, policy makers, and consumers can and must take to meet the water management challenges of a warming planet anticipating nine billion inhabitants by 2050.
