Forests
Home to animals found nowhere else, like the Zanzibar red colobus.

Protect the roots. Grow the future.
We help Tanzanian villages keep their forests standing, bring mangroves back to the shore and guard the beaches where turtles nest — with the people who live there leading the work.
Based in Tanga. Working from the Usambara Mountains to the Kilwa coast.

Our mission
Strong roots make a greener coast
Mizizi is Swahili for roots. Trees hold the soil, mangroves hold the shore, and neighbours hold each other to the plan. We fund, train and stand behind villages that choose to protect what grows around them.
Coasts
Mangroves and reefs that shelter fish, and the villages that fish them.
Communities
Every tree is planted, and guarded, by a neighbour.
Our programmes
Real work. Real places.
ForestsForest nurseries
Village nurseries raise native trees from locally collected seed. Families plant them where the forest has thinned, and are paid to keep them alive through the first dry season.
East Usambara foothills, Tanga Region
Goal for 2027250,000 native seedlings raised
CoastsMangrove return
Fishing communities replant mangroves on cut-over mudflats and guard them through the fragile first years. More mangroves, more nursery grounds for fish.
Rufiji Delta, Pwani Region
Goal for 2027120 hectares replanted
CoastsReef & turtle watch
Island monitors walk the nesting beaches at night, log every nest and run simple reef surveys. Data that belongs to the community, shared with the people managing the marine park.
Mafia Island
Goal for 202730 trained monitors on patrol
CommunitiesForests worth more standing
Beehives, fuel-saving stoves and small grants, so a standing forest earns a family more than charcoal does. Every grant is agreed in an open village meeting.
Kilwa coastal forests, Lindi Region
Goal for 2027400 households in forest-friendly work
Where we work
Four places, one coastline
We stay small on purpose: four sites we can visit every month, where we know the village chairs by name. Choose a site to see what happens there.

Every dollar, out in the open
This is how we plan to split each gift in 2026–27. When the year closes, we'll publish what actually happened next to it — including anything we got wrong.
- Village committees see the budget for their site.
- Annual accounts, independently audited, posted here.
- Restricted gifts stay with the programme you choose.
