Nexus as a Lens for SDG Implementation

Water is profoundly linked to the development and sustainability of all nations. It forms a natural connection across the Sustainable Development Goals, all sectors of the nexus, and even between countries. The Global Environment Facility (GEF) International Waters focal area realizes that the water, energy, and food nexus can be both a source of tension and an entry point for cooperation. The GEF works with island countries to tackle the nexus through an ecosystem-based approach known as Ridge to Reef (R2R). This chapter highlights some of the practical on-the-ground solutions demonstrated by national projects and how the GEF-UNDP Pacific Ridge to Reef Programme is creating entry points for enabling the water, energy, and food nexus that are aligned with the Sustainable Development Goal outcomes.
