Water-Energy-Food Nexus serves the SDG's
The Sustainable Development Goals (SDGs), adopted by the 2030 UN Agenda for Sustainable Development, are indivisibly connected with each other. The same holds for the specific objectives on climate change mitigation and adaptation according to the Paris Agreement (PA) adopted under the UN-FCCC. These connections allow finding effective and efficient solutions to tackle the world’s problems. SDG 6 (water), 7 (energy) and 2 (food security) are not only closely connected to each other but also eminently important for the Nexus approach. The 2030 UN Agenda for Sustainable Development highlights the need to think a common approach for the implementation of exactly those Nexus-linked SDGs. Only then the access-inequalities and the supply risks for water, energy and food can be reduced.
A Nexus perspective is therefore essential for promoting the integration of goals across sectors and reducing the risk of sector-specific SDG actions undermining each other. The nexus approach also analyses trade-offs and synergies between goals, and therefore serves as a ‘vehicle’ that boosts implementation of the 2030 Agenda.
As well as contributing to the SDGs, the nexus seeks to maximise poverty reduction and achieve economically and environmentally sustainable outcomes. The nexus and the SDGs are generally guided by the following common principles:
- Promotion of sustainable and efficient resource use
- Access to resources for vulnerable population groups
- Maintenance and support of underlying ecosystem services
