Welcome to N4W Call for Proposals.
Water security – defined as ensuring an adequate amount of good quality water is available – is a global challenge. The water we use every day is directly dependent on the landscapes through which it flows, yet nearly half of global drinking water sources are significantly degraded. Compounding factors, such as population growth, climate change, and poor planning are only further exacerbating water insecurity. Nowadays one in three people - over 2.2 billion people - still do not have access to safe drinking water.
From our experience, investing in watersheds, catchments and river basins, using Nature-based Solutions (NbS) at the landscape scale typically requires a long-term programmatic approach. We call this a ‘Watershed Investment Program’. The term ‘Watershed Investment Program’ (WIP) is deliberately meant to embrace a wide variety of related categories, including watershed management programs, water funds, river basin management programs, catchment management programs, etc. and encompasses initiatives designed to deliver water security benefits by deploying a defined portfolio of NbS interventions within a specified service area. However, organizing Watershed Investment Programs is complex, interdisciplinary, and requires substantial expertise to be successful. This is where Nature for Water (N4W) can help.
Nature for Water provides program preparation and implementation support to local organizations seeking to drive watershed health via at-scale deployment of Nature-based Solutions. Managed by The Nature Conservancy, N4W is composed of a diverse international team featuring expertise in hydrology, GIS, ecology, governance, stakeholder engagement, finance, and project management. We aim to deliver effective hand-in-hand support to local organizations across the program development lifecycle from preparation to implementation.
