Kitengela Wildlife Corridor Biodiversity Credits — EarthAcre (Kenya)

Nairobi National Park is fenced on three sides, with its open southern boundary onto the Kitengela plains providing the only route for wildlife, including lions, to move in and out. That corridor runs across privately owned Maasai community land, and as philanthropic funding for keeping it open has declined, the land has come under growing pressure for subdivision and development.

Keep the wildlife corridor open and intact by paying Maasai landowners directly for conservation, using a tradeable biodiversity-credit mechanism.

EarthAcre, a Nairobi-based biodiversity-credit developer, maps landowners and the area of land each has set aside for conservation, using remote-sensing methods developed with Harvard University researcher Andrew Davies to estimate biodiversity extent, alongside camera-trap wildlife monitoring.

In April 2025, the programme made its first biannual payment: USD 175,000 (about GBP 129,000) distributed to 256 landowners around Nairobi National Park, Amboseli and the Maasai Mara, for keeping more than 14,000 hectares (35,000 acres) of habitat open and intact, at a rate of USD 5 per acre per year.

This should be read as an early-stage market: only one payment cycle has been completed, EarthAcre both designs and verifies its own biodiversity-measurement methodology without independent third-party audit reported to date, and the scheme's financial sustainability beyond this first round is not yet demonstrated.
