Socio-economic Importance of the Coastal Zone
Human Settlements
• Six of the ten major residential centers are located on the coast. (Belize City, San Pedro, Corozal, Dangriga, Punta Gorda, Ladyville)
• 45% of the population resides in coastal areas (1999).
![Page 18: Vulnerability of the Caribbean to Climate Change](https://reader034.vdocuments.us/reader034/viewer/2022052308/56815a91550346895dc80516/html5/thumbnails/18.jpg)
Water Supply
• San Pedro– Desalination plant
• Placencia– Piped across lagoon
• Belize City– Supply located 17 miles inland– During drought, pumping limited to high tide– Salt water intrusion?

AVVA Vulnerability Analysis
• Entire coastline videotaped and analyzed in 1995
• Sea level rise of 4, 30 and 50 cm.
• Time periods of 25,50 and 100 yrs.
• Little impact in 25 yrs
• 50-100% of beaches lost in 100 yrs
![Page 20: Vulnerability of the Caribbean to Climate Change](https://reader034.vdocuments.us/reader034/viewer/2022052308/56815a91550346895dc80516/html5/thumbnails/20.jpg)
Ultimate Adaptation Option
• Belize City destroyed in 1931 and 1961 by hurricanes
• New capital (Belmopan) created 50 miles inland

Socio-economic Importance of the Coastal Zone
Agriculture• Small scale farming on
riparian lands, coastal plains, etc to meet local needs.
• Sugar generated approximately Bz$84.5 million (2000).
• Citrus farming (Mullins River to South Stann Creek) Bz$76 million in 2000.

Socio-economic Importance of the Coastal Zone
Agriculture continued• Banana (Sittee, South Stann Creek, Swasey and
Bladden Rivers) Bz$65 million.• Coastal communities of Corozal, Dangriga and
Independence heavily rely on these sectors

Vulnerability Studies in Agriculture
• 1995
• DSSAT
• Beans, corn and rice
• 1-2°C rise in temp
• ± 10-20% change in precip
• Result: 10-20% decline in yields
![Page 24: Vulnerability of the Caribbean to Climate Change](https://reader034.vdocuments.us/reader034/viewer/2022052308/56815a91550346895dc80516/html5/thumbnails/24.jpg)
Socio-economic Importance of the Coastal Zone
Industry and Commerce

Socio-economic Importance of the Coastal Zone
Oil Drilling• No major commercial fields for oil found.• Exploratory wells have been drilled, both inland and
offshore.
Bioprospecting Exploration and extraction of biological
diversity to be used for genetic and biochemical resources.
Possible multi-million dollar industry
Amendment to Fisheries Act Chapter 210 of 2000 includes bioprospecting.

Requirements/Suggestions
• Downscaling of global climate models• Vulnerability studies of other economically
important crops – bananas, citrus, sugar• Integrated vulnerability studies - salt water
intrusion• Improve data collection
– Topography, bathymetry, microscale monitoring
• Implementation of “no regrets” adaptation measures– IWRM, ICZM, EIA, Disaster mitigation

Other Concerns
• Forestry– 1999-2000– Pine bark beetle infestation– 75% of pine forest destroyed– High temps & high humidity– Poor management– Climate change signal?– Needs analysis– Impacts on timber industry and biodiversity– Contributes to emissions
