The Water-Energy-Food nexus in Africa needs to be understood and addressed in a highly regionally-integrated manner, especially in regions sensitive to climate change, where a marginal increase in temperature can reduce water levels, causing a major knock-on effect in the water supply system.
The implications of the Water-Energy-Food nexus have necessitated not only the convergence of various technologies to address the challenges pertaining to competing resources, but also the need for an institutional structure that embraces a cross-sector approach to resource governance.
It is evident that agricultural transformation and energy transition are interdependent and could be partly competitive. A stakeholder-driven nexus approach is proposed, underpinned by quantitative and spatially explicit scenario and planning tools, which should assist in resolving these types of challenges. It will also result in more consistent policy and decision making, improve resource productivities, lower environmental pressures and enhance human securities.
- The Water-Energy-Food nexus is a concept that recognises the inter-linkages between these three resources.
- The National Development Plan calls for large-scale agricultural development ‒ to combat the food crisis ‒ which will require large amounts of water.
- The intensification and modernisation of agriculture requires large amounts of water… and energy.
