The water-energy-food  nexus explicitly recognises the strong interdependencies of these three sectors and their high levels of exposure to climate change . With increasing societal demands on more variable water resources under climate change, an intensification of WEF competition and trade-offs are projected . Other interacting factors, for example, the increasing number of transnational investments in land resources can lead to localised increased competition for water resources . Understanding such nexus interlinkages can help characterise risks to water resource security, identify co-benefits and clarify the range of multi-sectoral actors involved in and affected by development decisions . Major barriers and entry points for greater integration include coordination of horizontal policy and integration of climate change adaptation actions , capturing the scarcity values of water and energy embedded in food/energy products , and inclusion of community-based organisations such as water resource user associations  and agricultural cooperatives .
