There is an increasing global demand for food, water and energy. All three are inter-linked, a fact that has increasingly become the focus of attention for policy makers and governments.
One initiative has been the Water-Energy-Food security nexus developed in Bonn by Holger Hoff under the auspices of the international climate change conferences of the parties (COP). The aim was to improve management of the complex links between water, energy and food systems. It is increasingly being used by international organisations to evaluate whether approaches to meeting development targets set out under the Sustainable Development Goals are coherent.
Understanding the connections between basic food demands and accessibility to water and energy is also important when it comes to climate change and its impact on agriculture and livelihoods. This issue featured prominently at COP22 in Marrakech in 2016.
