Understanding the Nexus


The Water, Energy & Food Security Resource Platform

Water, energy and food are essential for human well-being, poverty reduction and sustainable development. Global projections indicate that demand for freshwater, energy and food will increase significantly over the next decades. Nexus is a conceptual approach to better understand and to systematically analyse the complex interdependence of water, energy, and food systems, with the intention of managing trade-offs and co-benefits.

“It is increasingly clear: There is no place in an interlinked world for isolated solutions aimed at just one sector. If the world is going to reduce hunger and eradicate poverty, achieving security for water, energy and food is critical. This challenge is becoming even more critical with the impacts of climate change, and water will be the medium by which we will address much of the nexus.”
