The critical role of risk in setting directions for water, food and energy policy and research

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.
