The water–energy–food (WEF) nexus explicitly recognises the strong interdependencies of these three sectors and their high levels of exposure to climate change ( [[#Zografos--2014|Zografos et al., 2014]] ; [[#Dottori--2018|Dottori et al., 2018]] ; see Box 9.5). With increasing societal demands on more variable water resources under climate change, an intensification of WEF competition and trade-offs are projected ( [[#D’Odorico--2018|D’Odorico et al., 2018]] ; [[#Dottori--2018|Dottori et al., 2018]] ). Other interacting factors, for example, the increasing number of transnational investments in land resources can lead to localised increased competition for water resources ( [[#Messerli--2014|Messerli et al., 2014]] ; [[#Breu--2016|Breu et al., 2016]] ; [[#Chiarelli--2016|Chiarelli et al., 2016]] ). 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 ( [[#Kyriakarakos--2020|Kyriakarakos et al., 2020]] ). Major barriers and entry points for greater integration include coordination of horizontal policy and integration of climate change adaptation actions ( [[#England--2018|England et al., 2018]] ), capturing the scarcity values of water and energy embedded in food/energy products ( [[#Allan--2015|Allan et al., 2015]] ), and inclusion of community-based organisations such as water resource user associations ( [[#Villamayor-Tomas--2015|Villamayor-Tomas et al., 2015]] ) and agricultural cooperatives ( [[#Kyriakarakos--2020|Kyriakarakos et al., 2020]] ).
