Food Security in Haiti and
Global Environmental Change
Perspectives from
Université Quisqueya
GEC
Climate change (increase of CO2 and other
greenhouse gases lead to an increase in
temperature, changes in rainfall pattern and water
demand)
Studies related to global environmental change
stated that the tropical regions (such as Africa and
Latin America) will suffer more from the negative
impact of Global Environmental Change.
Assumption,
The more vulnerable is a country, the
poorer it will become over years.
The poorer is a country, the greater will be
the impacts of GEC on its food system.
The three components of food systems, with their main elements
FOOD
UTILISATION
FOOD
ACCESS
• Nutritional Value
• Social Value
• Food Safety
• Affordability
• Allocation
• Preference
FOOD
AVAILABILITY
• Production
• Distribution
• Exchange
Food Availability
Production
May decrease due to
Change in rainfall pattern
Shortening of rainy season
Increasing rain intensity
Flooding of low land areas
Increasing erosion phenomena
Severe droughts
Tendency to soil salinization ( saltiness)
Water scarcity
Food Availability
This is in harmony with the Ministry of
Environment 2001 Report on climate
change
This first Haitian report on climate change
(based on simulations performed on three crops
with the MAGICC-SCENGEN software)
reveals that by year 2030 and year 2060:
Food Availability
Production
White potato yield will decrease (even in
mountainous areas).
Rice yield will decrease due to a shortening of the
growing season linked to a reduction of all the other
phenological phases.
Corn yield will decrease because of a shortening of
some important phenological phases
Food Availability
Distribution
may be interrupted during the rainy season
due to the destruction of some vital
infrastructures (roads, bridges…)
This will hamper food circulation between
Port-au-Prince and the countryside.
Food Availability
Exchange
Importation will increase
Food Access
Affordability
purchasing power
decrease in agricultural yields
Frequent disasters (flood and drought)
Inflation (increase of food prices)
food unavailability
Food Access
Allocation
% of the income allocated to food
% income allocated to entertainment,
education, health
Food Access
Preference
no strong preference
Food Utilization
Nutritional value
Will decrease.
More glucide than protein
Food Utilization
Social value
Poverty will increase
Food Utilization
Food safety
Decrease as a result of
Increase external food dependency
All these will vary with the adaptation
capacity
Use of new crops and/or new varieties more
adapted to new environmental conditions
Adjustment of planting date
