Technical research aimed at resolving some of the overall and critical questions underlying the environmental and socio-economic issues of mangrove loss and restoration is essential.

The Project partners with several national institutions including the University of Guyana and with international researchers to fill research gaps.

Key topics with regards to the ecology of Guyana's mangroves which require further research include:

  • Where and how does agricultural pollution affect the growth of trees and the wildlife populations it supports throughout the year?
  • What are the best practices for planting, the causes of sudden erosion, pest, and disease among others, have not been answered in the specific context of the Guyana coast.
  • In addition to the values placed on sea defense, how do mangroves contribute to the maintenance of coastal biodiversity?
  • Conducting baseline stock assessments to understand how much fisheries are supported by mangrove ecosystems.
  • In addition, understanding livelihoods, the social dynamics, and how communities use and value this precious resource – mangroves – are important baseline information needed for its protection.

Addressing these and other questions will require the combined efforts of many agencies. Input from and collaboration with, at least, the Guyana Forestry Commission, Sea and River Defence Division, the Environmental Protection Agency, and all relevant departments within the University will be considered.

Value of mangroves for fisheries

Due to their complex physical structure and relatively high productivity, mangroves support a wide range of food chains including marine, estuarine, freshwater, and terrestrial which can be further subdivided by the source food, e.g., grazing food chains originating in leaves, seedlings, wood, fruits, etc., and detrital food chains (Lugo, 1980). The detrital food chains can be extremely complex as they originate from many kinds of litter, particulate detritus, dissolved organic materials, etc.

 Aside from their role as a food source, mangrove forests play an important role in maintaining commercial fisheries by providing nursery habitat, refuge from predators, for important species of fish and shrimp.

There is no research in Guyana that compares the export of detrital from mangrove areas and the amount of coastal fish production. It is not known for example how many fish species use mangroves as reproductive, nursery, or habitat areas at some point in their life cycle although recent surveys conducted in Golden Grove-Belfield mangrove reserve reported 16 species including commercially important species (Kalamadeen 2013). These uses can be documented through autecological research on commercially important species. Of importance to the Ministry of Agriculture, Fisheries Department is the determination the degree of dependence of commercial fisheries on mangrove detritus.   (Source: Review of Mangrove Research in Guyana (2013))


Economic Valuation of Ecological Services Provided by Mangroves

Mangroves are considered to be among the most productive ecosystems on earth, yet their economic, social and cultural values are often neglected in decision making and conflicts exist as to how best to use the land and forest resources. A major problem of mangrove resource management is how to assign value to products and services provided by these ecosystems as well as their perceived value. 

In Guyana a recent study by Ilieva (2013) estimated the total economic value of mangroves at USD1209 per hectare incorporating direct use values (fishing, ecotourism and apiculture indirect use values (carbon sequestration, biodiversity). This study did not evaluate the benefits in terms of coastal protection and non-use values of mangroves. In a recent study of the economic value of some mangrove services, Barbier et al. (2008) estimated the value of coastal protection from storms to be about USD 1.6 million per km2 of mangroves over a 20-year period. 

In Guyana there is a definite need for more research in this area – valuing Guyana’s mangroves as very little work has been done in this area. There is also the issue of the cost effectiveness of the GMRP planting programme where mangrove planting is done to complement hard sea defence structures. To this end there is need to determine the ecological as well as the monetary value of planted mangroves. This should be given high priority given the fact that it will give credibility to the GMRP and enable contributions from the GMRP to be balanced by decision makers against other alternative sea defences options in Guyana.Source: Review of Mangrove Research in Guyana (2013))

For Prospective Researchers and Institutions

Based on the Project's needs, NAREI welcomes interested academic institutions and researchers to partner with us. NARI will provide the following:

  • Access to transportation among pilot sites, when possible.
  • Access to office space, wireless internet, phone, printing and fax.
  • Access to available documents and resources on mangroves.
  • Facilitate clearing of administrative bottlenecks for meetings with key national stakeholders and institutions.

NB: Researchers and Academic Institutions are responsible for securing all relevant documentation and permission to conduct research within Guyana from the relevant Government Agencies. Research Proposals must to be submitted to NAREI at the same time when research application is submitted to the EPA etc.

Our Vision

To augment Guyana's sea defence by protecting, restoring and managing the natural coastline barrier provided by our mangrove forests.
