Strengthening the science behind mangrove protection

Guyana’s efforts to protect its natural environment must be supported by reliable information and the capacity to monitor changes taking place within its ecosystems. The relaunch of the Guyana Mangrove Information System (GuyMIS) is a welcome development, particularly at a time when the protection of the country’s coastline has become increasingly important to its long-term resilience and development.
For a country where much of the population, agricultural activity and economic infrastructure are concentrated along the coast, mangroves serve a purpose that extends well beyond environmental conservation. They provide a natural line of defence against coastal erosion, help reduce the impact of waves and support ecosystems that are important to biodiversity and livelihoods.
The threat posed by rising sea levels, climate change and coastal erosion makes their protection all the more necessary. Guyana has long relied on a combination of engineered sea defences and natural barriers to protect its low-lying coastal communities. Mangroves are an important part of that arrangement, helping to stabilise vulnerable areas, trap sediment, and provide habitats for numerous species.
Protecting these ecosystems means knowing where mangroves are located, understanding the pressures affecting them and being able to measure whether conservation efforts are producing the intended results. This is where GuyMIS can make a difference.
The upgraded system provides a centralised source of information, bringing together interactive maps, project records, research reports, photographs and educational resources. It allows information on mangrove distribution, restoration work, coastal changes and erosion-prone areas to be accessed in one place. More importantly, it provides a basis for making better-informed decisions about where intervention is needed and how resources should be directed.
There is also value in making this information accessible outside Government agencies. Students, researchers, community groups, and other interested stakeholders can use the platform to better understand the importance of mangroves and the work being undertaken to protect them. Conservation is more likely to gain public support when people have access to information about the ecosystems around them and understand what is at stake.
The investment already made in mangrove restoration demonstrates that this is an area of environmental protection receiving considerable attention. Over $592 million has been invested in mangrove restoration and coastal protection initiatives since 2020, with another $285 million budgeted for 2026. By the end of 2025, Guyana’s mangrove cover had expanded to more than 23,000 hectares.
These figures are encouraging, but expenditure and the number of hectares restored cannot, on their own, determine the success of the programme. What matters is whether restored mangroves survive and flourish, whether vulnerable coastal areas become more stable and whether the ecosystems continue to support biodiversity. Regular monitoring is essential to establishing this, and a properly-maintained information system can help provide that picture.
The timing of the GuyMIS relaunch is also significant as Guyana hosts the second annual Global Biodiversity Alliance (GBA) Summit. The gathering has brought international delegates together to discuss practical approaches and financing for biodiversity conservation. It is an opportunity for Guyana to demonstrate that its environmental commitments are being supported by initiatives that can produce measurable results at home.
Guyana has much to contribute to the international conversation on biodiversity. Its extensive forests, freshwater resources, and marine ecosystems are significant natural wealth.
Conservation cannot rest on declarations, international conferences or financial commitments alone. It requires sound scientific information, cooperation among institutions and consistent action. Systems that help identify vulnerable ecosystems, establish priorities and track the results of interventions are an important part of that process.
Still, the value of GuyMIS will depend largely on how well it is maintained and used. The National Agricultural Research and Extension Institute, which developed the system with support from the Global Green Growth Institute, will need the continued cooperation of agencies and institutions that hold relevant environmental information. A centralised platform can only be as useful as the information it contains. Regular updates and a willingness to share data must, therefore, become part of the way these institutions operate.
Guyana’s development agenda, particularly through the Low Carbon Development Strategy, has placed considerable emphasis on balancing economic growth with environmental protection. As the country continues to expand its economy and develop its infrastructure, that balance will become increasingly important. The protection of mangroves is part of this responsibility, given their contribution to coastal security, biodiversity, and the communities that depend on healthy ecosystems.
The relaunch of GuyMIS should be seen as an opportunity to strengthen the way Guyana monitors and manages an important natural resource. As international attention turns to Guyana for the Global Biodiversity Alliance Summit, the initiative provides an example of how environmental commitments can be translated into national action.
