Declining water availability also has a negative impact on food and energy security e.g. for hydropower and irrigation. However, the water, energy and food sectors are often managed separately, potential leading to conflict and ineffective actions. This paper describes the role of River Basin Organisations to improve the governance of the so-called water-energy-food nexus. Good practice examples have been identified and recommendations given. This paper has been ordered by UNEP Nairobi and is developed in cooperation with Water Health.
