The accelerating pressures of climate change, population growth, resource scarcity, and ecosystem degradation demand a decisive shift from fragmented, sector-based management towards integrated and forward-looking governance approaches. The Water–Energy–Food–Ecosystem (WEFE) nexus has emerged as a critical framework for understanding the interdependencies and trade-offs across key resource systems. However, despite its growing prominence in policy and academic discourse, operationalizing the WEFE nexus remains a persistent challenge for many regions, due to institutional silos, governance gaps, data limitations, and mismatches between planning and implementation scales.
Against this backdrop, the session “From Silos to Synergy: Accelerating the WEFE Nexus” aims to move beyond high-level narratives and explore practical pathways that can transform nexus thinking into coordinated and actionable interventions. The session will examine how sectoral silos can be broken through shared planning processes, joint monitoring mechanisms, and coherent governance approaches that recognize water, energy, food, and ecosystems as an interconnected system rather than isolated sectors.
Particular attention will be given to enabling institutional frameworks, effective knowledge-exchange mechanisms, and multi-stakeholder coordination platforms that can foster more equitable and efficient water use. Evidence from global and regional experiences demonstrates that integrated approaches such as climate-smart agriculture, renewable energy integration, integrated basin management and sustainable water management can generate multiple benefits simultaneously, enhancing productivity while protecting ecosystem integrity and reducing systemic risks
The session will also emphasize the catalyzing role of digital technologies, such as remote sensing, Earth observation, big data analytics, and AI-supported forecasting systems, in strengthening evidence-based policymaking, improving cross-sectoral data interoperability, and supporting adaptive decision-making under climate uncertainty.
The session will also consider how urban innovation and territorial approaches including, green and blue infrastructure, circular water systems, and water-sensitive planning, can serve as basin-scale and replicable models for integrated WEFE implementation. As urban areas concentrate water, energy, and food demand, cities offer practical entry points for translating nexus principles into investment and planning decisions with tangible outcomes.
By bringing together policymakers, practitioners, scientists, and innovators, the session seeks to demonstrate how cross-sectoral collaboration and digital innovation can unlock tangible, multi-benefit WEFE outcomes. Drawing on as a hosting country of COP 31, Türkiye’s experience alongside global and regional perspectives, the session will offer replicable insights that contribute to climate resilience, sustainable development, and the transition from isolated interventions to synergistic, system-wide solutions.
