INTERACT-Bio is a four-year project designed for improving the utilization and management of nature within fast-growing cities and the regions surrounding them. It aims to provide expanding urban communities in the Global South with nature-based solutions and associated long-term benefits.

The project will enable governments at all levels – from local to national – to integrate their efforts for mainstreaming biodiversity and ecosystem services into core subnational government functions such as spatial planning, land-use management, local economic development and infrastructure design.

The project will support city-regions to understand and unlock, within their specific local context, the potential of nature to provide essential services and new or enhanced economic opportunities, while simultaneously protecting and enhancing the biodiversity and ecosystems on which these services and opportunities depend. In doing so, these actions will place the participating city-regions on a more resilient and sustainable development path.

INTERACT-Bio is being implemented in Brazil, India and Tanzania.

Three city-regions in Tanzania are integrating biodiversity and bringing nature back into cities.

This uniquely biodiverse region faces challenges from rapid urbanization, agricultural encroachment, timber extraction and charcoal production that results in land degradation, over-extraction of natural resources, pollution and habitat loss. These challenges demand strategies that integrate biodiversity into urban planning, both conserving and reaping the benefits of natural resources.

Dar es Salaam
Dar es Salaam, Africa’s fastest growing city, is situated in the eastern region of Tanzania on the Indian Ocean. The city boasts several natural habitat elements such as mangroves, marine systems, coastal forests and wetlands but faces challenges such as coastal erosion, poor waste management, polluted waters and harmful unregulated fishing practices.


Arusha is situated in northern Tanzania below Mount Meru on the eastern edge of the Great Rift Valley.  The city is located near some of the greatest national parks and game reserves in Africa including Serengeti National Park and Ngorongoro Conservation Area.  Arusha has a long track record of biodiversity awareness and has committed to conserving natural assets but faces challenges such as deforestation and rapid unplanned urban growth.

The municipality of Moshi is situated in northern Tanzania near the Kenyan border, on the lower slopes of Mount Kilimanjaro. The municipality has invested in integrating natural elements through city greening but faces challenges of waste management, pollution due to plastics in the environment, and development activities along river banks.

INTERACT-Bio aims to provide these city-regions with nature-based solutions and mainstream biodiversity considerations.
Participating city-regions will integrate nature-based solutions into city planning and draft Local Biodiversity Strategies and Action Plans. The project will also bring together national and subnational actors for integrated dialogue on the importance of biodiversity benefits.
