As global climate talks convene at #COP30 in Belém, Brazil, one reality is clear: the climate crisis is a water crisis. Worsening floods and droughts are disrupting water supplies around the world, threatening livelihoods and stability. The Green Climate Fund (GCF) is pioneering a comprehensive approach to tackle the water–climate crisis. Rather than isolated, one-size-fits-all projects, GCF emphasizes flexible, integrated solutions tailored to each country’s needs. It supports “delegated, need-based” initiatives that empower national entities and local communities to design multi-sector interventions spanning water, food, energy, and ecosystems. This nexus approach ensures water projects deliver broad benefits – for example, pairing flood control with improved agriculture and habitat restoration – and remain robust under uncertainty. It aligns with GCF’s country-driven model: through direct access partnerships and programmatic funding, countries drive the projects, speeding up implementation and scaling up what works.
At the heart of GCF’s strategy are six strategic pathways addressing water challenges from all angles – economic, technical, social, and environmental:
- Water as an Asset Class – Elevating water’s economic and ecological value to attract investment and encourage sustainable management.
- Innovative & Fit-for-Purpose Finance – Deploying creative financing (blended finance, loans, equity, guarantees, etc.) tailored to make water projects bankable.
- Transboundary Partnerships – Fostering cross-border collaboration so regions jointly manage shared water resources and climate risks.
- Adaptive & Agile Water Governance – Reforming policies and institutions for nimble, inclusive water management that can adjust to climate impacts.
- Dynamic Policy–Innovation Engine – Creating feedback loops between field innovation and policy, so pilot projects inform national strategies and knowledge spreads quickly.
- Climate-Enabled Circular Water Systems – Moving to “close the loop” on water by reusing wastewater, harvesting rain, and recovering resources to reduce waste
GCF water security and sanitation projects guidelines To help countries design bankable, climate-resilient water and sanitation projects, GCF developed a three-part Water Project Design Guideline series.
