Tanzania is one of Africa's most biodiverse countries, with globally important forests, savannahs, wetlands, freshwater systems and marine and coastal ecosystems. This natural wealth underpins tourism, fisheries, agriculture and the livelihoods of millions of people. Yet biodiversity is increasingly threatened by habitat degradation, unsustainable resource use, climate change, invasive species and growing pressure on terrestrial and marine ecosystems. Securing sufficient and sustainable finance for conservation is therefore critical to protecting Tanzania's natural capital and the economic activities that depend on it.

UNDP BIOFIN began its work in Tanzania in 2018, initially focusing on Zanzibar, where marine and coastal ecosystems are particularly important for tourism, fisheries, seaweed farming and local livelihoods. UNDP BIOFIN's assessments estimated that Zanzibar requires approximately US$69.4 million over five years to meet its biodiversity priorities, with a financing gap of around US$43.4 million. In response, the Government endorsed the Biodiversity Finance Plan in 2022, identifying 13 priority finance solutions to mobilize new resources, improve existing expenditure and redirect finance toward biodiversity-positive outcomes.

The programme has since moved from planning to implementation. UNDP BIOFIN is supporting reforms to protected-area fees and digital revenue collection, public–private partnerships, the repurposing of potentially harmful subsidies and other innovative finance solutions. Following Zanzibar's progress, UNDP BIOFIN expanded to mainland Tanzania in 2025, where the Government is developing the evidence and financing framework needed to mobilize greater public and private investment for biodiversity and implement national and global biodiversity commitments.

Transforming Protected Area Finance in Zanzibar

UNDP BIOFIN supported Zanzibar in reviewing visitor fees for marine and terrestrial protected areas and introducing a new fee structure in August 2025. Combined with improved revenue collection, the redesign is projected to increase annual conservation revenues from approximately US$1.3 million to more than US$4.3 million, potentially more than tripling the resources available for protected-area management.

Nearly US$1.9 Million Already Generated

The initiatives are already producing measurable results. Since the new fee structure was introduced in August 2025, Zanzibar generated nearly US$1.9 million in two quarters, already exceeding the revenue collected during the whole of 2024. In the fourth quarter of 2025 alone, revenues reached US$921,530, compared with US$364,827 during the same period in 2024, an increase of approximately 153%.

Digitalizing Conservation Finance

In May 2026, the Revolutionary Government of Zanzibar and UNDP BIOFIN launched a new Digital Cashless and Tourism System for marine and terrestrial protected areas. Visitors can pay conservation fees through mobile money, bank transfers, and credit cards, while authorities can monitor revenues in real time. The system is designed to reduce revenue leakage, increase transparency and strengthen the long-term financial sustainability of protected areas.

Establishing Zanzibar's Biodiversity Finance Framework

UNDP BIOFIN supported Zanzibar in completing its Policy and Institutional Review (PIR), Biodiversity Expenditure Review (BER) and Financial Needs Assessment (FNA), leading to the development and government approval of the Biodiversity Finance Plan in 2022, formally launched in 2023. The Plan identified 13 priority finance solutions to diversify and increase financing for biodiversity.

The Financial Needs Assessment estimated that Zanzibar requires approximately US$69.4 million over five years, or around US$13.9 million annually, while the estimated biodiversity financing gap is approximately US$43.4 million.

Redesigning Harmful Subsidies

Another important UNDP BIOFIN workstream is the identification and redesign of potentially harmful subsidies in fisheries and seaweed farming. These sectors are particularly important to Zanzibar's coastal economy and livelihoods, but poorly designed incentives can contribute to pressure on marine ecosystems. The Biodiversity Finance Plan therefore prioritizes repurposing harmful fisheries subsidies and promoting more sustainable seaweed production.

Mobilizing Private Investment for Biodiversity

UNDP BIOFIN is also supporting the integration of biodiversity into Zanzibar's Public-Private Partnership framework. Tourism, the blue economy, fisheries, agriculture, forestry and other sectors have been identified as opportunities for mobilizing private investment that can simultaneously support economic development and biodiversity conservation.

Expanding UNDP BIOFIN to Mainland Tanzania

Following the pioneering implementation of UNDP BIOFIN in Zanzibar, the Vice President's Office and UNDP formally launched UNDP BIOFIN in mainland Tanzania in March 2025. The programme is establishing the evidence base needed to identify Tanzania's biodiversity financing needs, assess existing expenditure and develop a Biodiversity Finance Plan aligned with national priorities and the Kunming–Montreal Global Biodiversity Framework.

Finance solutions

The Biodiversity Finance Plan serves as a meticulously devised strategy, outlining 13 prioritized financial solutions, itemized below. The implementation of these solutions is anticipated to substantially mitigate the identified financial gap concerning the conservation of biodiversity within Zanzibar. These solutions are:

  1. Crowdfunding for restoration of degraded key forests and/mangroves in selected Community Forest Management Areas (CoFMAs);
  2. Establish Payment for Ecosystem Services (PES) Programme for CoFMAs and other forests generating significant water ecosystem service.
  3. Repurpose potentially harmful subsidies in the fisheries sector;
  4. Establish and operationalize public-private partnership (PPP) framework for “Re-greening Zanzibar Program” (coastal and inland areas);
  5. Repurpose potentially harmful subsidies for sustainable seaweed farming;
  6. Secure Debt-for-nature swaps for sustainable BLUE economy (coral reefs restoration);
  7. Establish Blue Fund for BLUE Economy implementation;
  8. Establish crowdfunding for restoration of degraded coastal and beach areas;
  9. Identify and develop a new program for scaling up of REDD+ initiatives;
  10. Introduce subsidies for clean energy sources (e.g., gas and electricity) for household energy;
  11. Increase Corporate Social Responsibility (CSR) contributions from the private sector for biodiversity conservation;
  12. Review tourist’s entrance fee structure for protected areas and adopt a Digital Voucher System for the fees collection; and
  13. Review and strengthen the revenue retention framework/Scheme for terrestrial PAs and Marine Conservation Areas (MCAs).
