Introduction

The Nexus approach highlights the interdependencies between achieving water, energy and food security for human well-being, e. g. basics services and economic development, while ensuring ecologically sustainable use of globally essen­tial resources. It is based on an understanding of the synergies and regulated negotiation of fair trade-offs between compet­ing uses of water, land and energy-related resources.

The Nexus approach is a fundamental shift, from a pure sectoral approach to solutions that embrace a cross-sectoral, coherent and integrated perspective. It challenges existing structures, policies and procedures at global, regional and (sub) national levels.

The three "supply securities" water, energy and food depend on ecosystems and on each other. The three resources land, water and energy (atmosphere) are part of this ecosystem and must be used and protected in a balanced manner.
