Climate Change and its potential impact on Guyana
![Page 3: Mangroves and Climate Change](https://reader034.vdocuments.net/reader034/viewer/2022051319/588b06b61a28ab233d8bd693/html5/thumbnails/3.jpg)
.
Over 90% of Guyana’s population live and work in the coastal zone. Guyana’s coast is below sea level, in some areas by as much as 1.4 metres. Main livelihoods, economic activities and infrastructure of the country extremely vulnerable to climate change impacts.

Guyana’s Second National Communication (SNC) to the United Nations Framework Convention on Climate Change (UNFCCC) predicts higher incidents of disasters such as flooding and water intrusion derived from storm surges, sea-level rise, and intense precipitation.

The severity of droughts and intensity of floods in various parts of Guyana is likely to increase.

Decrease in yield of crops as temperature increases in different parts of Guyana
By 2030, the annual loss due to flooding in Guyana is projected to be US$150 million.

Mangroves and Climate Change
![Page 8: Mangroves and Climate Change](https://reader034.vdocuments.net/reader034/viewer/2022051319/588b06b61a28ab233d8bd693/html5/thumbnails/8.jpg)
Current rates of mangrove loss are roughly estimated at around 150,000 hectares (370,050 acres) per year, or about 1% per annum ( FAO).
Mangrove loss = Loss of carbon sequestration potential
Per hectare, mangrove forests store up to five times more carbon than most other tropical forests around the world.

Mangroves Values and Functions
Roots help to reduce and prevent coastal erosion.
Act as wave breakers to protect coasts, coastal communities and infrastructure from the onslaught of strong waves and winds.
Good breeding, feeding and nursery areas for many species of terrestrial and aquatic species.
Provide an excellent habitat for different types of plants and animals.
Root systems act as sediment traps and reduce the amount of sediment that enters the marine environment.

Combination of natural and man made factors has resulted in a mangrove forest which is out of equilibrium and unable to withstand the natural erosive cycle and recover during the accretion cycle

To abate climate change (carbon sequestration
through reforestation and forest
preservation) and to mitigate its effects
(sea defence, biodiversity).

Work with communities to raise
awareness and understanding about
the importance of mangroves.
Understand what is preventing
natural regeneration at individual
sites - research.
Continue to monitor and protect
existing mangrove forests.
Using the principles of EMR and
lessons learned, continue to restore
degraded forests.
