OVERVIEW OF THE CARIBBEAN FOOD SYSYEM
•
Production of traditional export crops (bananas, sugar, coffee, cocoa and rice)
PRIORITY
•
Production of non traditional crops for domestic and regional consumption (root crops, vegetables and fruits)
•
High input, labor intensive agriculture
•
Minimal usage of irrigation techniques, high dependence on rainfed agriculture
•
Agriculture practiced on marginal lands
•
Limited livestock production
•
Some level of self sufficiency in fish provision
EFFECTS OF AGRICULTURAL PRODUCTION ON THE ENVIRONMENT
•High input agriculture leading to chemical build up in the soils, eutrophication of rivers, water quality degradation •Production on marginal lands, deforestation leading to high incidences of soil erosion, flash flooding, sedimentation in rivers •Micro-climate changes - changing soil pH, soil microbe interaction etc •Loss of biodiversity due to mono-cropping production system •Increase methane emission by livestock
FOOD PROVISION IN THE CARIBBEAN
Production = f (yield, area) Availability = f (production, distribution) Access = f (availability, socioeconomic potential [e.g. affordability], & physiological potential [e.g.nutritional quality]) Provision = f (production, availability, access)
FOOD PRODUCTION
Crop production •traditional export crops (banana, sugar etc) •domestic/regional production (root crops, vegetables and fruits) Fisheries •local consumption and export Livestock •large poultry industry •devloping small ruminant industry Agro- procecssing •large scale processing of traditionally exported crops (sugar and rice) •processing for non traditional exports (fish, fruits and veg, etc) •cottage industries
FOOD AVAILABILITY
•
Revenue generation from exports of traditional crops, service, tourism, and manufacturing
•
High imports of cereals and cereals preparation; meat and meat preparation; dairy products and eggs; and fruits and vegetables - Imports are mainly from North American and European countries
•
Increased food availability in the region over the past 25 years due to the influx of cheaper imports
•
Domestic production affected by seasonality (dependence on rainfed agriculture) further increasing dependence on imports
•
Limited agroprocessing in the region
•
Lack of structured food storage systems/absence of food reserves
FOOD ACCESS
•
The limiting factor to food access in the region is the economic and physiological potential of people to purchase food.
•
The urban poor are the ones likely not to have the purchasing power to access food
•
The rural areas have limited purchasing capacity and nutritional security becomes a more critical problem to these people
Global Environmental Change
Changes caused or strongly influenced by human activities
•
Land cover & soils
•
Atmospheric composition
•
Climate variability & means
•
Water availability & quality
•
Nitrogen availability & cycling
•
Biodiversity
•
Sea currents & salinity
•
Sea level
FEATURES OF CLIMATE CHANGE
The IPCC has reported that by the year 2100:
•
Rise in global average surface temperature of 1.4 - 5.8°C relative to 1990
•
Rise in sea level by 0.09-0.88m
•
Changes in variability, frequency and intensity of extreme climate events
SYSTEMS THAT CAN LEAD TO EXTREME WEATHER EVENTS IN THE CARIBBEAN
•
Tropical depressions, storms and hurricanes intense and high volume rainfall, strong winds and rough seas
•
Tropical waves - spawn tropical storms and hurricanes, potential to cause intense rainfall and high sea swells
•
Inter tropical convergence Zone (ITCZ) - Potential to cause intense rainfall and often interacts with tropical waves
•
Upper level Troughs intense rainfall results in explosive cloud development and
•
Cold front intrusion - results in rainfall in the eastern Caribbean during the dry season
•
El Niño related droughts
SOME PROJECTED IMPACTS OF CLIMATE CHANGE Crops
•
reduction in crop yields
•
reduced water availability
•
salt water intrusion Livestock
•
increased heat stress related deaths Fisheries
•
habitat degradation
•
fluctuations in fish abundance
•
changes in upwelling rates
PROGRESS ON REGIONALISING GCMs
Regional GCMs have grids which are too large for small islands and as such climates of small islands are being predicted to change in the same way as the surrounding oceans The Climate Studies Group, University of the West Indies, Mona (CSGM) has a project involving dynamic downscaling using regional climate models (RSM, MM5 derivatives. This project is being done in conjunction with the international research Institute for Climate Prediction and with MACC/CPACC

ONGOING WORK ON CLIMATE CHANGE IN THE REGION
1. Caribbean Planning for Adaptation to Global Climate Change (CPACC) which began in April 1997, and it’s follow-up Caribbean Mainstreaming Adaptation to Climate Change (CMACC). 2. Development of the Caribbean Community Climate Change Centre 3. University of the West Indies, Mona
GECAFS PROJECT DEVELOPMENT
1.
GECAFS Caribbean Food Systems “Issue Identification” Workshop, Trinidad, April 22 – 23 2002; and 2. “Developing a Research Agenda for the
Caribbean Food System to respond to Global
Climate Changes.” Trinidad, 19-20 September, 2002
WHAT MAKES THE GECAFS PROJECT?
Help develop policy at regional level, based on an interdisciplinary approach
Clearly identify, and demonstrate end-user involvement in all stages
Have a clear GEC dimension
Include all 3 GECAFS Themes with a strong design for “internal” integration
Include capacity development
Identify, build upon and add value to suitable ongoing regional research (e.g. CPACC, UWI etc)
APRIL WORKSHOP
Purpose: To identify main policy-related issues for a GECAFS study on the Caribbean Food System as a key step in developing detailed research plans Objectives:
Establish clear priorities for policy-relevant research issues within the GECAFS framework
Identify principal potential collaborators
Identify research issues that could contribute to existing and planned regional programmes
Design follow-up meeting and draw-up preliminary invitee list
APRIL WORKSHOP
(cont’d)
Outcomes:
•Sensitization Caribbean scientists to GECAFS GECAFS Team to the Caribbean Food System •Identification of priority policy issues - note that no policies specific to GEC •Identified key players and collaborators in assisting with the development of the GECAFS project
SEPTEMBER WORKSHOP
Purpose:
Review key Climate Change impacts research and identify critical research topics
SEPTEMBER WORKSHOP
(cont’d)
Outcomes:
1.Recognition that GEC was broader than GCC and that discussions should be held in that context 2. Recognition that the GECAFS project has to incorporate all three science team and a MULTI disciplinary approach is needed 3. Development of a project under the GECAFS principles
