How community-led data is reshaping fisheries governance in West Africa

In coastal communities across West Africa, data is rebuilding trust, shifting power, and opening doors that were previously closed to those most affected by fisheries decline. 

From November to December last year, Blue Ventures facilitated community-led fisheries data feedback sessions in The Gambia, Senegal, and Cabo Verde, which revealed what is possible when local actors both generate and own evidence. With more than 150 participants, these sessions demonstrated the growing momentum behind community-driven data.

Rebuilding dialogue in the Gambia: towards trust

At the outset, collaboration between civil society partners and the Department of Fisheries in The Gambia was still in its early stages and required trust-building. Gunjur Conservationists & Ecotourism Association (CETAG) and Sanyang Youths for Environmental Protection and Development (SANYEPD), both deeply rooted in fisher communities, were committed to community-led monitoring, with initial institutional agreements set to last only one year.

To support this process, Blue Ventures facilitated dialogue, clarified roles, and helped partners align around the shared understanding that data belongs to communities and their organisations.

After nine months of data collection at the Gunjur and Sanyang landing sites, fishers, fishmongers, civil society organisations, government representatives, and the media gathered for a feedback session. The room became something rare: a space where community-generated data could be openly shared, questioned, and taken seriously.

Awa Rane Ndoye, Blue Ventures’ Head of Technical Capacity for the region, presented a first-of-its-kind fisheries data dashboard in The Gambia. The data revealed a high proportion of juvenile fish in catches, particularly for Bonga, which was one of the most widely consumed fish species in Gambian households.

Abdoulaye Ndiaye, Blue Ventures’ Campaign Manager, framed data as a bridge rather than a battleground, a tool to support advocacy, accountability, and better policy.

Fishers and officials spoke openly about declining fish sizes, the realities of fishing practices, and the disconnect between existing regulations and ecological realities. Rather than deepening tensions, the data created common ground.

 Just weeks later, CETAG confirmed that a revised five-year MoU with the Department of Fisheries had been signed, a milestone directly rooted in the trust built through these sessions.

For CETAG and SANYEPD, this marked a transformation in how community data is recognised, forming a credible foundation for long-term collaboration and evidence-based policy change.

“This is a monumental achievement for CETAG and SANYEPD. Being the first initiative of its kind in the entire subregion makes it even more remarkable. This data will significantly strengthen our advocacy efforts and, I believe, play a crucial role in guiding national fisheries policies,” declared Ahmed Manjang, CETAG Coordinator.

Advancing shared responsibility for fisheries in Senegal

In Djiromaite, Senegal, on 7 December 2025, the conversation advanced from dialogue to concrete action.

Working with the Ufoyaal Kassa-Bandial Marine Protected Area (MPA) management committee, communities gathered to review data they had collected themselves and reflect on what it revealed about local fisheries and enforcement challenges. 

Community members spoke candidly about the seasonal practices they already use to support stock recovery, including rest periods and alternative livelihoods. They reflected on how these practices could inform MPA management, surveillance, and community engagement.

The session highlighted communities’ commitment to shared responsibility. They expressed their willingness to collaborate more closely with MPA authorities, participate in surveillance systems, and use their data to support concrete action. 

It concluded with community-driven recommendations to strengthen communication with MPA authorities.

Chief Niantang, the village head of Djiromaite, wrapped up the session by stating, “Now that we have the data and a clear understanding, we commit to holding an internal village session to guide our decisions. These are our own resources, and it is our responsibility to address our challenges. No one else will do it for us”.

Women leading evidence-based fisheries change in Cabo Verde

On Maio Island in Cabo Verde, the power of ownership took centre stage.

During a data feedback session organised by Blue Ventures’ partner Fundação Maio Biodiversidade (FMB) in Calheta on 29 November 2025, eight women fishmongers presented a full year of fisheries monitoring they had led themselves. 

They recommended biological rest periods during months when fish sizes consistently fell below legal limits. The proposal, grounded entirely in community-collected evidence, was met with strong applause.

“We haven’t had an event like this since 2013. These results show that communities are essential actors in the preservation of biodiversity and that initiatives like this deserve to be financed,” said Janete Agues from FMB.

Government representatives and scientists from Instituto Do Mar (IMAR) described the moment as unprecedented. It was the first time they had seen community members both collect and analyse fisheries data, as well as propose concrete, evidence-based management measures.

“We will integrate this community data into our official statistics to provide more reliable information for the development of fisher communities,” added Abertinho Martins from IMAR.

The impact quickly extended beyond Maio, inspiring interest from neighbouring islands and calls to scale the model nationally.

Community-owned data that changes fisheries systems

Across The Gambia, Senegal, and Cabo Verde, the contexts differed, but the lesson was the same.

By centring fishers and fishmongers, especially women, as knowledge holders and decision-makers, such initiatives can rebuild trust and reshape fisheries governance systems, laying the foundations for sustainable, inclusive, and resilient artisanal fisheries across West Africa.

Cabo Verde

At least 6,000 fishers and 3,500 processors – mostly women – and sellers are active in the fisheries sector. Almost all artisanal-caught fish is sold and consumed locally, but fish from the distant-water industrial fleet accounts for 80% of exports from Cabo Verde.

BV works closely with the local NGO Fundaçao Maio Biodiversidade to support communities to use robust data to inform fisheries management and improve value chains. Our partnership has so far focussed on Maio island, but we have plans to scale this approach to at least five of the ten islands that make up the archipelago.

Unlike other countries in West Africa, there is no practice of community management in Cabo Verde, although there are a variety of community associations on the islands that represent fishers’ interests. BV is supporting partner organisations to strengthen the capacity of these groups to move towards the co-management of marine resources and the development of community-driven protected areas.

The Gambia

The Gambia’s coastline is only 80km long, but is home to a rich mangrove ecosystem that supports locally important fisheries. Sadly, much of the coastline has been devastated by sand and ilmenite mining, uncontrolled property development (including in protected areas), and a rapid ratcheting up of industrial fishing effort, largely to feed the country’s three fishmeal and fish oil factories.

Our approach in The Gambia is to empower local actors including CETAG and Gambian Environmental Alliance to raise their voices against these drivers of environmental destruction, and find community-led solutions. BV is also working with the well-respected youth and women groups SANYEPD and Hallahin Women Oyster Farmers to help communities secure preferential access to fish and shellfish.

Senegal

Fishing and the collection of shellfish is central to the lives of most coastal dwellers in Senegal, and seafood is part of almost every meal in the country. 

But massive overfishing by both industrial and artisanal fleets, as well as increasing exports of fishmeal for aquaculture, is threatening the way of life and food security in the country. As fish stocks dwindle, the staple National dish of Senegal “Thiebou Djeun” –  “Fish and Rice” – is becoming a luxury for many. 

Blue Ventures’ work in Senegal is focused mainly in the Sine-Saloum and Casamance deltas   of the country, home to hundreds of thousands of hectares of fish-rich mangroves. We have teamed up with Kawawana, Senegal’s oldest LMMA (known locally as APAC), to support the protection of 18,000 hectares of mangroves, and to help monitor and manage the rich fisheries they contain. Through our partners Nebeday and EcoRurale, we are also working with other communities, and especially women groups, to put in place community-based fisheries management systems, focusing particularly on the oyster and shellfish collection that are major sources of income in estuaries and deltas.

We’re new to Senegal but working to scale our communities-first approach to more partners and communities. We’re also aiming to build alliances with grassroots, national, regional and other like-minded organisations to advocate for better marine protection and to strengthen national inshore exclusion zones for small-scale fishers in which industrial fishing is restricted.

Guinea-Bissau

The West African country of Guinea-Bissau is home to the unique Bijagos archipelago, a network of some ninety mangrove-fringed offshore islands and extensive mudflats supporting large amounts of migratory bird species, as well as megafauna such as manatees, dolphins, and sea turtles. The Bijagos people continue to live a very traditional lifestyle, where the collection of marine invertebrates plays an important role in food security and cultural traditions. The country is also home to extensive mangrove-fringed river systems that support rich fisheries.

Blue Ventures has been working with Tiniguena, one of the oldest conservation groups in Guinea-Bissau, to support the establishment of the country’s first community-led MPA, in the Bijagos islands. Guinea-Bissau is a new venture for us, and we envision scaling to new partners and communities in the coming years. Our focus is on data-driven community-led management of fisheries, which are of enormous importance to coastal communities, in particular women.

Timor-Leste

Since 2016, our work in Timor-Leste has evolved into a dynamic movement supporting community-led marine management and coastal livelihood diversification in Asia’s newest country. From our origins on Atauro Island, considered to harbour the most diverse coral reefs on earth, we’re now working with numerous communities on the island and the mainland to help improve management of critical coral reefs and seagrass ecosystems.

We’re helping communities reinvigorate traditional community governance practices − known as Tara Bandu − to support marine conservation, in particular through the use of temporary and permanent fishing closures, and community-led monitoring of marine ecosystems and fisheries.

We’re helping communities come together to exchange their experiences of conservation across their shared coastline, building a new movement of local support for systems change in the management and conservation of Timor-Leste’s coastal waters.

Alongside our community conservation efforts, we have also pioneered Timor-Leste’s first homestay association, which has provided income from visiting ecotourists on Atauro Island.

Our team in Timor-Leste’s capital Dili works closely with government, civil society organisations and NGO partners.

Tanzania

Like its neighbours within the Northern Mozambique Channel marine biodiversity hotspot, Tanzania harbours some of the most diverse marine ecosystems in the Indian Ocean. These habitats are facing unprecedented challenges from overfishing and climate change. 

The Government supports the use of co-management to improve the management of marine resources, but a community’s ability to be meaningfully involved in this partnership approach is all too often hampered by the capacity of its institutions, to organise and to acquire the skills and resources they need. 

Our Tanzanian team has worked with communities and local organisations to support locally led marine conservation since 2016. Our work has expanded from Zanzibar to the mainland regions of Tanga, Lindi and Kilwa. Our technicians work with local partners to help communities strengthen co-management systems, through Beach Management Units (BMUs), Shehia Fishing Committees (SFCs), and Village Liaison Committees.

We have three types of partners in Tanzania: NGOs, CSOs and government. Our NGO implementing partners Mwambao Coastal Community Network, Sea Sense, and Jongowe Development Fund have spearheaded a remarkable acceleration in the uptake of community-based fisheries management and conservation in recent years, notably through the use of short-term fisheries closures to catalyse broader community conservation.

Our CSO partners include Kilwa BMU Network, NYAMANJISOPOJA CFMA and Songosongo BMU, while our government partners comprise the Ministry of Fisheries in Mainland Tanzania, and the Ministry of Fisheries in Zanzibar, as well as local government authorities in Pangani and Kilwa.

Following the conclusion of the SWIOFish project in 2021, we are also working with partners on an initiative to support the establishment and functioning of a fisheries co-management forum. The forum will facilitate engagement between national and local government authorities and NGOs involved in fisheries co-management initiatives along the Tanzania mainland coast, with the aim of enhancing networking and strengthening management and governance.

Somalia

With one of Africa’s longest coastlines, Somalia’s diverse marine environment supports enormously productive coastal and offshore fisheries.  Decades of conflict have undermined the country’s capacity for fisheries management, with many foreign industrial vessels fishing with impunity, and little regard for the critical importance of Somalia’s coastal fisheries for local livelihoods and food security.

A period of relative political and social stability unprecedented in recent decades is now presenting new opportunities to address past challenges, and to realise the considerable opportunities that well-managed coastal fisheries and conservation can offer Somalia. We are forging partnerships with community organisations in Somalia to build their capacity and skills to help coastal communities manage their fisheries for food security, livelihoods and conservation.

Philippines

The Philippines forms part of the ‘coral triangle’ epicentre of global marine biodiversity, with unparalleled diversity of marine species.  Over half of the country’s 107 million people live in rural areas, and approximately three quarters depend on agriculture or fisheries as their primary source of livelihoods.

Through our partnership with People and the Sea, we are supporting communities in the eastern Visayas to set up and utilise participatory data systems to monitor and understand the status of their fisheries, in a way that is meaningful for them. Through provision of access to strong data systems and training in data collection this year, these communities will soon have access to real time fisheries data and visualisations that will enable them to make informed decisions around the management of their fisheries.

Indonesia

Indonesia comprises almost 17,500 islands stretching across three time zones. This archipelagic nation has the 2nd longest coastline in the world − and the largest coastal fisheries resource − of any country on Earth. More than ninety per cent of Indonesia’s seafood production comes from small-scale fisheries, which are underpinned by the planet’s most biodiverse marine ecosystem, known as the Coral Triangle.

We have supported community-led marine conservation in Indonesia since 2016. Our team works in close partnership with 17 Indonesian organisations supporting community-based approaches to coral reef and mangrove conservation across 81 communities in fourteen provinces, collectively reaching over 80,000 people. 

Since 2019 we have brought these partners together within a peer learning network of Indonesian organisations specialised in supporting community-based marine conservation. The network is based on the shared values of the organisations, including a commitment to promote the rights of traditional fishing communities in conservation. Our support across these communities is customised to each context − the local fisheries, community stakeholders, seafood supply chains, legal frameworks and customary traditions governing fisheries management and conservation.

In Sumatra and Kalimantan we are strengthening our work in community conservation of globally important mangrove forests. We are supporting and strengthening community-forest management and supporting local partners who are adapting our catalytic model for temporary fishery closures to mangrove-dependent fisheries like mud crab.

We are working closely with our local partners Forkani, Yayasan LINI, Yapeka, Yayasan Planet Indonesia, Foneb, Komanangi, JARI, Ecosystem Impact, Yayasan Tananua Flores, Yayasan Baileo Maluku, AKAR, Japesda, Yayasan Citra Mandiri Mentawai, Yayasan Mitra Insani and Yayasan Hutan Biru, Yayasan Pesisir Lestari and Lembaga Partisipasi Pembangunan Masyarakat (LPPM) Ambon.

Kenya

Kenya’s coast supports an extraordinary diversity of tropical marine and coastal habitats.  These waters are threatened by a proliferation of destructive fishing practices and over-harvesting within the artisanal and commercial fishing sectors.

Our approach in Kenya focuses on strengthening Beach Management Units (BMUs) to improve fisheries management. Since 2016 our Mombasa-based technical team has provided support, mentoring and assistance to local partners including Coastal and Marine Resource Development (COMRED), the Lamu Marine Conservation Trust (LAMCOT), Bahari Hai, and Kwale Beach Management Unit Network (KCBN), a network of 23 BMUs in Kwale County

These partnerships have seen notable achievements in community-led fisheries management and conservation, including training and mentoring BMU leaders in eighteen communities in Kwale and Lamu Counties.

Belize

Belize’s marine environment encompasses some of the most diverse marine ecosystems in the Caribbean Sea, including vast coral reefs, mangrove forests and seagrass beds. We have maintained a permanent presence in Belize since 2010, supporting diverse fisheries and conservation efforts.

We work in close partnership with the Belize Fisheries Department, MPA managers, fishing cooperatives and fishers’ associations, and championed the establishment of a national scale domestic fishery targeting the invasive lionfish.  We are actively promoting community led fisheries management, building on the success of our pioneering work with management of invasive lionfish.

We’ve led a decade-long MPA monitoring and evaluation programme in Bacalar Chico Marine Reserve, and provide regular training in coral reef monitoring methods to MPA authorities across Belize, including helping establish management targets for Turneffe Atoll Marine Reserve, Belize’s largest MPA.

Our team supports and strengthens  fishing associations that advocate for the rights of their communities to be involved in decision making around access and use of coastal fisheries and to be key members of MPA management groups. Across the country we are working to ensure that fishers interests are mainstreamed in the design and implementation of marine conservation and fisheries management, improving the effectiveness of co-management of coral reef, mangrove and seagrass areas.

Madagascar

Blue Ventures’ journey began in Madagascar in 2003, and we’ve been supporting communities in marine conservation across the country ever since. We have five regional field programmes along Madagascar’s west coast, as well as regional offices in the towns of Ambanja, Mahajanga, Morondava and Toliara. Our national headquarters is located in the capital Antananarivo.

Across all these sites we support communities with the establishment of locally managed marine areas (LMMAs), and work with government partners to secure national recognition for community conservation initiatives. First developed in Madagascar by Blue Ventures in 2006, the LMMA concept has since been replicated by communities at hundreds of sites over thousands of kilometres of coastline, now covering almost one fifth of Madagascar’s inshore seabed. Our research in Madagascar has demonstrated globally important evidence of the benefits of LMMAs to fisheries and conservation.

Our work focuses on strengthening community institutions in marine management and governance, and pioneering new approaches to catalyse community engagement in ocean conservation. These innovations have included establishing community led ecological monitoring and the country’s first mangrove blue carbon project.

At the national level, we partner with the LMMA network MIHARI, which brings together 25 partner conservation organisations supporting 219 LMMA sites across the country. Our policy team is also actively involved in advocating for more robust legislation to safeguard the rights and interests of fishing communities, and to remove destructive industrial fishing from coastal waters. In 2022 we supported the launch of Fitsinjo, an industrial fisheries watchdog organisation. The network highlights industrial fishing and IUU activities in Madagascar and the broader Western Indian Ocean region.

Given the lack of basic services in remote coastal regions in Madagascar, we also help communities access basic healthcare through training and supporting women to serve as community health workers. We do not replace government health systems, but work to strengthen existing structures in close collaboration with government health actors and specialist NGOs. We also incubate Madagascar’s national health-environment network, which brings together 40 partner organisations to address the health needs of communities living in areas of conservation importance across the country.
