These resources provide various goods and services that meet the needs of the population, including agriculture providing food (and biomass), energy transformation providing power and heat, and water supply providing clean water services and sanitation. Finally, the third domain transcends the sectoral scope and highlight how the resources in the nexus, through the economic services they provide, contribute to a range of policy objectives; obvious examples include “security of supply” for food, water and energy, welfare and environmental quality. Food security is defined in the 1996 Rome Declaration on World Food Security as “when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life” (FAO, 1996). Similarly, the IEA defines energy security as “uninterrupted physical availability at a price which is affordable, while respecting environmental concerns” (Jewell, 2011). However, the broader connotation, i.e. a movement in the direction towards security, is more relevant for this report: do the bottlenecks in the nexus, and the policies that aim to address these, bring the world closer to the objectives of security of supply.
