Potentials of Water-Energy-Food Security Nexus Approach as an Option for Implementation of Climate Change Policies: A Perspective for Nigeria

The increasing demand for essential resources such as water, energy, and food, driven by rapid population growth, urban expansion, and industrialisation, poses a significant challenge for developing countries, which is further exacerbated by climate change. Implementation of climate change policies, therefore, requires adequate consideration of the interconnection between water, energy, and food executed on synergies and managing tradeoffs, which most often is lacking in some developing countries like Nigeria. This paper assesses the relevance of the water-energy-food (WEF) nexus approach and highlights its role in formulating sustainable climate policies. In this review, a narrative and exploratory approach was carried out through a literature search from international databases such as Google Scholar and Scopus to capture the full range of perspectives between the years 2002 and 2025 that have contributed to the emergence of the WEF nexus approach in formulating sustainable climate policies. Enhanced resource efficiency, improved resilience to climate change, reduced environmental degradation and innovation and technology development are some of the benefits of the WEF nexus approach. Given the intricate interconnections among these resources, integrating the WEF nexus into policymaking is essential for ensuring long-term resource security and sustainability. This approach fosters a comprehensive and strategic framework for embedding water, energy, and food considerations into climate governance
