Solutions to the food shortage, demand for clean water, and need for energy for a current world population of 7 billion are the greatest challenges today, which require technological innovation and changes in public policy. This new book provides a broad overview of the nexus of water-food-energy and its relationship with climate and sustainable development, which have huge impact on water and food availability. The volume presents case studies for the management of water, energy, agricultural growth, and food security using empirical analyses and technological interventions. It explores innovations in sustainable food production; energy solutions using biofuels, solar energy, and magnetic energy; and water conservation management.
