The Water-Energy-Food (WEF) nexus is critical for sustainable development, particularly in regions facing increasing resource demands and climate change impacts. This webinar will delve into the intricate interdependencies of water, energy, and food within the commercial and industrial sectors, emphasising the urgent need for integrated, technology-driven strategies to ensure water security. Key discussion points will include understanding the WEF nexus challenges and opportunities, exploring innovative solutions for sustainable water use across interlinked sectors, and balancing water security with energy and food production demands. Through case study analyses, such as the Cape Town water crisis and its subsequent water strategy, the webinar will highlight the importance of proactive coordination and technology adoption. We will examine water-efficient practices in agriculture and beverage production, and address the challenges of securing water resources in energy-intensive industries. Furthermore, the session will discuss the relevance of technology-assisted frameworks for the WEF nexus, analyzing risks to agriculture and food security, and demonstrating how smart WEF innovations can contribute to resource efficiency and sustainability goals.
