The devastating effects of climate change, structural inefficiencies in water use, and exceeding the capacities of ecosystems necessitate a paradigmatic shift in international water policies. Water is not merely a resource, but an integral part of regional stability, economic competitiveness, public health, energy, food, and ecosystem components.
Water efficiency is one of the most powerful tools for sustainable development and increasing resilience against the impacts of climate change, while providing mutual benefits for all components involved in the food, water, energy, and ecosystem nexus.
From transitioning to pressurized systems in agricultural irrigation and process water recirculation in industry, to reducing water losses in urban infrastructure and real-time monitoring technologies, moving forward with measurable, verifiable, and reportable goals across a wide range of areas will support economic growth while reducing the risk of water scarcity. Achieving greater benefits with less water must be at the heart of future global policies.
The Water Efficiency session will provide a vital platform for policymakers, representatives of international organizations, scientists, and funding institutions to discuss solutions that will shape the future of water management in the context of food, water, energy, and ecosystem nexus connectivity. Sectoral interaction regarding water efficiency practices, prioritization of investments, and financial optimization are fundamental pillars of sustainable resource management.
Aligned with the Strengthening Water Resilience: Innovation to Action theme of the 5th Istanbul International Water Forum, the session also contributes to the global momentum toward the UNFCCC COP31 to be hosted by Türkiye and the UN 2026 Water Conference.
Objectives and expected outcomes:
Keywords: Water efficiency; water governance; water-food-energy-ecosystem connectivity; climate adaptation; integrated water management and governance; water resilience; cross-sectoral cooperation; alignment with and contribution to SDG 6.4 (Water use efficiency).
