Water-energy-food nexus perspective: Pathway for Sustainable Development Goals (SDGs) to country action in India

Abstract

Water, energy and food securities lie at the heart of the Sustainable Development Goals (SDGs). Since these securities are interconnected, the business-as-usual approach (sectoral approach) cannot achieve them and need to apply the water-energy-food nexus approach for identifying and overcoming the roots of barriers and challenges. The study aims to prioritize interlinkages between SDG-2 (food security), SDG-6 (water security) and SDG-7 (energy security) for country action. In order to achieve this aim, the study implements a set of methods including stakeholder perception survey, network analysis, regression analysis and cross-sectorial group discussion. This article summarizes the outcomes of a case study in India. Stakeholders cognition derived through scrutinizing the perception survey admitted the need for a nexus approach in the action plans towards the SDGs. Quantitative assessment of interdependency showed that, of 182 interlinkages between SDG-2, SDG-6 and SDG-7 targets, 124 interlinkages had synergistic relation. The combined outcome of the cross-sectorial group discussion identified eight interlinkages as high priority (p>0.9) for immediate integrated planning and action. A total of ten interactions are moderate (p=0.6 to 0.9) and eight are low priority interlinkages (p<0.6). Solid understanding of synergies and trade-offs associated with SDG targets and initial prioritization of interlinkages would help India reorient its SDG priorities from a water-energy-food nexus perspective.
