UNDESA (2014), Chapter 6 on "The Climate-Land-Energy-Water-Development Nexus”, Prototype Global Sustainable Development Report. 

Sustainable development highlights the need for integrated approaches to finding solutions that are commensurate with the challenge of achieving economic, social and environmental goals that are often interlinked. The climate–land–energy–water– development (CLEWD) nexus is of great importance for sustainable development.

Water, energy and land are needed to grow food. Some food crops can also be used as biofuel. Power plants require water. Energy intensive seawater desalination increasingly provides water for drinking and agriculture. Water and energy infrastructure is needed to spur development and vice versa. In many parts of the world, a changing climate exacerbates some of these already strained links. Increasing droughts call for increased energy inputs for irrigation and limit the use of hydropower plants. In some SIDS, as well as in drought-sensitive areas, these impacts of a changing climate are already a reality. In many cases, these links are so significant that they cannot be neglected by policy and call for integrated approaches.

The case studies presented in this chapter highlight the importance of scientific evidence in supporting sustainable development policy
