The sustainable development goals (SDGs) challenge markets, regulators and practitioners to achieve multiple objectives on water, food and energy. This calls for responses that are coordinated and scaled appropriately. Learning from water–energy–food nexus could support much-needed building of links between the separate SDGs. The concept has highlighted how risks manifest when blinkered development and management of water, food and energy reduce resource security across sectors and far-reaching scales. However, three under-studied dimensions of these risks must be better considered in order to identify leverage points for sustainable development: first, externalities and shared risks across multiple scales; second, innovative government mechanisms for shared risks; and third, negotiating the balance between silos, politics and power in addressing shared risks.

AbstractWe analyse the threats of global environmental change, as they relate to food security. First, we review three discourses: (i) 'sustainable intensification', or the increase of food supplies without compromising food producing inputs, such as soils and water; (ii) the 'nexus' that seeks to understand links across food, energy, environment and water systems; and (iii) 'resilience thinking' that focuses on how to ensure the critical capacities of food, energy and water systems are maintained in the presence of uncertainties and threats. Second, we build on these discourses to present the causal, risks and options assessment for decision‐making process to improve decision‐making in the presence of risks. The process provides a structured, but flexible, approach that moves from problem diagnosis to better risk‐based decision‐making and outcomes by responding to causal risks within and across food, energy, environment and water systems.
