Nexus and Value Chain

Nexus and Value Chain explores how energy decisions interact with water and food systems, and why integrated, risk-informed planning is needed to manage cross-sector trade-offs. It emphasizes co-production—co-design, co-development and co-evaluation—between knowledge producers, intermediaries and users to deliver actionable services. It also highlights data sharing and robust data management as foundations for model calibration, interoperability and reliable decision support.

Water-Energy-Food (WEF) Nexus

The WEF nexus frames the interdependencies and trade-offs among water, energy and food, noting that water is required for both food and many energy technologies. Nexus thinking supports integrated, risk-based decisions and complements resilience approaches under climate variability and change.

Co-Design, Co-Development, Co-Evaluation (CO-CO-CO Approach)

The CO-CO-CO approach defines co-production as an iterative process—co-design, co-development, co-evaluation and delivery—linking knowledge producers, intermediaries and users. It helps translate complex, probabilistic climate information into usable products, with evaluation and value assessment built in.

Data Sharing, Processing, and Management

Data sharing enables the development, calibration and validation of energy models; using multiple data sources improves simulations and forecasts. The page outlines challenges—large data volumes, quality control and interoperability—and stresses data management plans and FAIR-aligned exchange to support decisions.
