Vulnerability of the Caribbean to Climate Change The Coastal Zone of Belize Carlos Fuller Caribbean Community Climate Change Centre (CCCCC)
2
Projected Temperature Rise Annual mean temperature change, 2071 to 2100 relative to 1990: Global Average in 2085 = 3.1 o C
3
Projected Change in Precipitation Annual mean precipitation change: 2071 to 2100 Relative to 1990
6
Impacts of Climate Change in the Caribbean US Country Studies Programme GFDL, CCC, UKMO, GISS Temperature rise (1-2°C) Change in rainfall patterns (±10-20%) Sea level rise (4- 50 cm)
7
Sea Level Rise Erosion Coastal flooding Inundation Saltwater intrusion Mangroves Tourist destinations Human settlements Water supply Agriculture Aquaculture Fisheries
8
Socio-economic Importance of the Coastal Zone to Belize Adapted from a presentation by: Ms. Tanya Williams
9
The Coastal Zone of Belize Complex system comprised of: i.the barrier reef ii.the three offshore atolls iii.hundreds of patch reefs iv.extensive seagrass beds v.mangrove forests vi.>1,000 cayes
12
The Coastal Zone Home to several endangered species such as: i.the West Indian Manatee ii.American crocodile iii.marine turtles and, iv.several birds
13
Socio-economic Importance of the Coastal Zone Tourism 60% of the estimated 172,300 tourist arrivals in 1999 visited sites in the coastal zone. Approx. 7,000 employed in the industry. Single largest contributor to Belize’s economic growth.
14
Branching coralBrain coral Coral bleaching events are expected to increase
15
Socio-economic Importance of the Coastal Zone Fishing Direct employment 2000 – 3000 employed per year. Indirect employment through processing, sales and maintenance. Subsistence fishing In 1999, total financial value was Bz$19.4 million
16
Socio-economic Importance of the Coastal Zone Aquaculture Eight farms in operation 3,000 – 4,000 acres on pine ridge coastal lands. Generates approximately Bz$62.5 million
17
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).
18
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?
19
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
20
Ultimate Adaptation Option Belize City destroyed in 1931 and 1961 by hurricanes New capital (Belmopan) created 50 miles inland
21
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. Picture: Government Press Office
22
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
23
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
24
Socio-economic Importance of the Coastal Zone Industry and Commerce Major centres located in the coastal zone (main centers – Independence, Belize City, Ladyville and the Corozal Commercial Free Zone). Employ a national total of approximately 5,600. Garment industry generated approximately Bz$40 million in 2000.
25
Socio-economic Importance of the Coastal Zone Ports Three main ports: Belize City, Commerce Bight and Big Creek. Commerce Bight – citrus products Big Creek – banana
26
Socio-economic Importance of the Coastal Zone Marine Dredging 1999 = 168,010 cubic yards of dredging. Primarily for landfill or for navigational purposes.(State of the Coast Report 1999) Most operations are related to tourism or real estate developments. (State of the Coastal Zone Report 1995)
27
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.
28
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
29
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
