Marine Conservation.
Coral reef surveys, seabed mapping, seagrass assessments, marine protected area support, blue carbon, and community-based ocean management.
Overview
Tanzania's coastline stretches over 1,400 kilometres, and together with Zanzibar, it hosts some of the most diverse and valuable marine ecosystems in the entire Indian Ocean. Coral reefs, seagrass meadows, mangrove forests, and open ocean habitats support millions of people through food, income, and coastal protection. Yet these ecosystems are under serious and growing threat.
At Blue Green Tanzania Consult, marine conservation is at the heart of what we do. We have hands-on experience working in Tanzania's coastal waters, and we understand both the science and the human dimensions of protecting the ocean. Below are the specific areas we work in and the issues we actively address.

Coral Reef Monitoring and Assessment
Coral reefs are the most productive ecosystems in the ocean, but they are dying at an alarming rate. Rising ocean temperatures are causing coral bleaching events that are becoming more frequent and more severe. We conduct systematic reef health assessments using scientific survey methods to understand where reefs are healthy, where they are stressed, and what interventions are needed. We use underwater photography, transect surveys, and digital tools including AI-assisted image analysis to generate reliable data that managers and policymakers can act on.

Seagrass and Seaweed Ecosystem Surveys
Seagrass meadows are among the most underappreciated ecosystems on the planet. They store carbon, provide nursery habitat for fish, and support the dugongs and sea turtles that many coastal communities depend on. We conduct detailed seagrass assessments to map their extent, assess their health, and understand the threats they face from pollution, boat damage, and coastal development. We also work on seaweed, both its ecological role and its growing importance as a livelihood crop for coastal women and communities.

Benthic Habitat Mapping
The seabed, what scientists call the benthic zone, is the foundation of the entire marine ecosystem. Knowing what is down there, how much of it exists, and how it is changing over time is essential for good marine management. We have extensive experience in systematic seabed mapping, having surveyed thousands of grid points along Tanzania's coast. We use grid-based photography at multiple depths, process the imagery on platforms like Coral-Net, and produce maps and reports that feed directly into marine protected area planning and fisheries management.

Marine Protected Area Management and Support
Tanzania has a network of marine parks and reserves, but having a protected area on paper is very different from managing it effectively on the ground. We support the planning, assessment, and strengthening of Marine Protected Areas and Marine Managed Areas, working with park authorities, communities, and government to improve patrolling, monitoring, boundary management, and enforcement. We also help assess whether existing protected areas are actually achieving their conservation goals.

Blue Carbon and Climate Finance
Mangroves, seagrasses, and coastal wetlands are extraordinary carbon sinks, they absorb and store far more carbon per hectare than most forests. This makes them central to climate change mitigation, and increasingly, they are attracting finance from international climate funds. We help NGOs and government agencies understand, measure, and monetise the carbon stored in these ecosystems, connecting coastal conservation to global climate funding streams like the Green Climate Fund, the Global Environment Facility, and voluntary carbon markets.

Illegal, Unreported, and Unregulated Fishing
Destructive fishing practices including dynamite fishing, beach seining, and the use of undersized nets continue to devastate fish populations and coral reefs in Tanzania. We work with Beach Management Units, fisheries authorities, and coastal communities to strengthen surveillance, reporting, and enforcement of fishing regulations, and to build community understanding of why sustainable fishing practices are in everyone's long-term interest.
- 07 / 09
Mangrove Restoration and Protection
Mangroves are being cleared at a rapid rate for charcoal, building materials, and coastal development. Yet they are critical nursery habitats for fish, protect coastlines from erosion and storm surge, and are powerful carbon stores. We support mangrove mapping, restoration planning, and community-led replanting programmes, always making sure that restoration is done with the right species in the right places, not just to hit a numbers target.
- 08 / 09
Ecosystem Valuation
One of the main reasons marine ecosystems are destroyed is that their value is invisible, nobody puts a price on a healthy reef or a seagrass meadow. We conduct ecosystem goods and services valuations that calculate in monetary terms what these ecosystems provide, from fisheries production and coastal protection to tourism revenue and carbon storage. These valuations are powerful tools for making the case for conservation investment and for informing government policy.
- 09 / 09
Community-Based Marine Resource Management
The most effective marine conservation in Tanzania happens when communities are in the driver's seat. We support the establishment and strengthening of community co-management structures, Beach Management Units, Village Natural Resource Committees, and Co-Management Boards, giving fishing communities the tools, knowledge, and legal standing to manage and protect their own marine resources.
