NATURE FOR DEVELOPMENT

NATURE FOR WATER SECURITY

Level: Introductory | Estimated completion time: 2 hours | Certificate upon completion

Skills: Understanding nature’s role in water systems, applying nature-based solutions to water management, linking water security to global goals, recognizing water-related risks and trends

Water security depends on healthy ecosystems. Forests, wetlands, and grasslands regulate water flow, filter pollutants, and build resilience against droughts and floods. This journey explores how nature-based solutions can protect and restore water resources while supporting biodiversity, climate adaptation, and sustainable development. Through practical examples, case studies, and tools, you’ll learn how to integrate nature into water policy, planning, and management strategies.
