Green Water. What is it?
It's the water flowing through the leaves of a baobab tree. The moisture suspended between grains of sand in the Sahel. The rain held in the soil of a Malawian smallholder's field, waiting to be pulled up by roots. It's the water that 80% of small-holder farming in Africa depends on, and that 95% of the continent's staple food production runs on.
And yet it receives just 5% of public agricultural funding.
Why Africa?
Because 60% of the world's cultivable but unused land sits in Sub-Saharan Africa. Because most of the continent has few perennial rivers, no dam can hold green water, no pipeline can divert it. It lives in soil, plants, and air, managed not by ministries but by farmers, foresters, and pastoralists, the front-line stewards of Africa's water.
Blue water vs. green water, briefly:
Blue water is what we usually picture: the liquid in rivers, lakes, wetlands, and aquifers, water we can pump, dam, and pipe. Green water is rainfall that infiltrates the soil and is taken up by plants, or returned to the atmosphere through evapotranspiration. Rainfed agriculture runs entirely on green water. Irrigated agriculture uses both. The concept was introduced by Swedish hydrologist Malin Falkenmark in 1995, and three decades later, it's still the most undervalued resource on the continent.
Where you come in:
The Green Water Africa Film Prize is a short film competition (3-5 minutes) open to filmmakers, scientists, students, artists, and anyone with a story to tell. We're looking for portraits of place, people, and practice: terraces, half-moons, agroforestry, mulching, both ancient and emerging techniques that hold water in the land. We welcome fiction, documentary, animation, whatever form carries the story.
Bring us stories of the water you've seen.
Submissions should present portraits of local geographies and address themes such as water conservation, climate resilience, biodiversity preservation, and social cohesion. Ideally, submitted films will also highlight their potential to inspire modern solutions.
Building on the experience of Let’s Talk About Water and its collaborations with UNESCO programmes, this initiative aims to mobilise storytelling to highlight innovative, inclusive, and culturally rooted water solutions across Africa.
Why You Should Participate:
By making short films, you can inspire, inform, and promote action around water issues and solutions. The Water Film Prize challenges you to explore these ancient water management methods not as historical artifacts, but as blueprints for tomorrow's innovations. Arid regions face mounting pressures from climate change, migration, and the abandonment of traditionally managed landscapes.
Your film will be seen by film and water experts, and stands a chance to win cash prizes! Whether you are a student, filmmaker, artist, activist, hydrologist, ecologist, geographer, or social scientist, grab your camera and share your water story.
About the Organizers:
Let’s Talk about Water (LTAW) is a global platform that for 20 years has used the power of film to bridge the gap between scientists, policy-makers and the public, creating vital dialogue about water challenges and solutions across the globe.
Let's Talk About Water will award films that best illuminate solutions that are especially crucial today, learning from the past and applying it to the future. An international panel of film and water experts will assess the films. These are the prize categories.
1st Prize - $3000 USD
2nd Prize - $2000 USD
3rd Prize - $1000 USD
Finalists (3) - $1000 USD
Honorable Mentions (2) - $500
Winning films will be announced and premiered on March 16th, 2027, at the Let’s Talk About Water Film Festival (Paris, France), the Luxor African Film Festival (Luxor, Egypt) and other venues in 2027. A small selection of winners will also be showcased at the African Film Festival New York 2027.
