Today's oil and gas are at record prices, whilst global energy demand is increasing from population and economic development pressures. Climate change, resulting in large part from the burning of fossil fuels, is exacerbating the impacts of the excelerated exploitation of our natural resources. Therefore, anxieties over energy, water, and climate security are at an all-time high. Global action is needed now in order to address this set of urgent challenges and to avoid putting the future of our civilization at risk. This book examines the powerful interconnections that link energy, water, climate and population, exploring viable options in addressing these issues collectively. Difficult political decisions and major reforms in resource governance, policies, market forces, and use are needed and this book provides excellent introductory material to begin to understand and to address these problems.
