Abstract
Population growth, economic development, and climate change pose critical challenges to water, energy, and food security of the cities in emerging nations of the Asia-Pacific region. The unprecedented urbanization growth in the Asia-Pacific region during the past century has triggered the need for food-water-energy nexus thinking in cities. The biggest 100 cities of the Asia-Pacific region together are contributing annually around 20% of global gross domestic product (GDP) and 29% of GDP growth. Over half of the populace of this Asia-Pacific region will be living in cities by 2025. Asia-Pacific region cities will need to increase their food supply by 77% by 2050, and consequently, water and energy consumption will increase. This chapter deals with the food-water-renewable energy nexus in some Asia-Pacific cities. The interaction of Sustainable Development Goals (SDGs) and food-water-energy nexus with a focus on renewable energy is mentioned first. The status and progress of renewable energy use for water, energy, and food are then reviewed. Recent research is highlighted, and key challenges and opportunities such as fragmented and inconsistent policies are discussed. We conclude that cities need to make decisions to ensure integrating renewable energy for the city-level water-energy-food nexus, and achievement of SDGs, such as sustainable cities and communities (SDG 11) and climate action (SDG 13).
