The IYRP Working Group on Pastoralists & Water, where SIWI is a member and representing the research project Restore4More, has published a new Call to Action, "Managing green water for healthy rangelands and sustainable pastoral futures," as part of the International Year of Rangelands and Pastoralists (IYRP) 2026.
The Call to Action argues that healthy rangelands and resilient pastoral livelihoods depend on “green water” — rainfall that infiltrates soil, is stored soil moisture and in trees and plants and circulates back to the atmosphere as evapotranspiration, sustaining ecosystem services like soil fertility, biodiversity and climate regulation. Water policy for rangelands has traditionally centred on “blue water” — the visible water in rivers, lakes, and aquifers — even though the availability and quality of that blue water depend directly on how rainfall is captured and cycled through soils and vegetation upstream.
The document calls on all those working in and with rangelands and pastoral areas to recognize the fundamental role of green water in shaping healthy rangeland ecosystems, and to actively manage it as a foundation for rangeland resilience, water and food security, sustainable blue water development, and pastoral livelihoods and cultures. It outlines three priority areas for action:
- Supporting pastoral mobility — grazing calendars, seasonal access arrangements, secured mobility corridors — so vegetation and soils can recover and sustain green water functions.
- Restoring soils and landscapes to capture and retain rainfall, through reseeding native vegetation, assisted natural regeneration, water harvesting structures, and gully control.
- Embedding green water in governance and finance, so national water, land, climate, and agricultural policies — and climate/biodiversity finance — recognize and reward pastoral communities for managing green water.
The Call to Action builds on the working group’s first Call to Action, “Sustainable Water Development in the Pastoral Rangelands,” published in June 2025.
Both will be presented in the session “Chasing the Water – Pastoralists and Grazing” at World Water Week 2026, Tuesday 25 August, 12:00–13:00 CEST (online), which explores why pastoral mobility matters and how blue and green water must be managed together for resilient rangelands.
