Caribbean region must boost efforts to prepare for increased drought – UN report
The report, Drought Characteristics and Management in the Caribbean, found that the Caribbean region faces significant challenges in terms of drought, FAO said.
“Drought ranks as the single most common cause of severe food shortages in developing countries, so this is a key issue for Caribbean food security,” said Deep Ford, FAO Regional Coordinator in the Caribbean.
The Caribbean region already experiences drought-like events every year, with low water availability often impacting on agriculture and water resources, and a significant number of bush fires, FAO noted.
The region also experiences intense dry seasons, particularly in years when El Niño climate events are present. FAO said that the impacts of this are usually offset by the next wet season, but wet seasons often end early and dry seasons last longer, with the result that annual rainfall is less than expected.
The Caribbean region accounts for seven of the world’s top 36 water-stressed countries, while one of them – Barbados – is in the top 10, according to FAO.
Impacts of drought on agriculture and food security
With droughts becoming more seasonal in nature in the Caribbean region, agriculture is the most likely sector to be impacted, with serious economic and social consequences, FAO emphasized.
This is particularly important because most of Caribbean agriculture is rainfed. With irrigation use becoming more widespread in the region, countries’ fresh-water supply will become an increasingly important resource, FAO said.
Small-scale, family farmers, are particularly vulnerable to drought – low rainfall threatens rainfed crops and low water levels result in increased production costs due to increased irrigation.
Extensive droughts also cause increased vulnerability in livestock as grazing areas change in nutritional value, with more low quality, drought tolerant species dominating during such dry spells. In addition, the potential for livestock disease outbreaks also increases, FAO said.
Drought also often results in food price increases. Expensive, desalinated water resources are becoming more important in the Caribbean, accounting for as much as 70 per cent in Antigua and Barbuda, and this can impact significantly on the ability of poor households to afford food.
Rural communities can also face a greater scarcity of drinking water during droughts. In such cases, children are at the highest risk from inadequate water supplies during drought.
New challenges posed by climate change
The most frequently occurring natural hazards in the Caribbean are climate-related, and their impacts may increase due to climate change, FAO said. The region’s vulnerability to climate related hazards is manifested in loss of life and annual economic and financial losses that result from strong winds, flooding and drought.
Between 1970 and 2000, the Caribbean region suffered direct and indirect losses estimated at between $700 million and $3.3 billion due to natural disasters associated with weather and climate events.
So far, the region has focused mainly on floods and storms, and it currently lacks effective governance, expertise, and financial resources to deal effectively with drought issues, FAO stressed.
It also has poor national coordination, policy-making, and planning in place. While many regional and national programmes have developed responses to build resilience against the impacts of drought, the report found that too many of these are still only in a drafting phase, or are poorly implemented and in need of review.
Regional frameworks provide a necessary first step
The FAO report noted that the severity of the 2009-2010 drought – the worst in more than 40 years – served as an alarm bell for the Caribbean region.
The event forced the region to consider, particularly in light of climate change projections, the need to introduce more strategic planning and management measures to avert the potential disaster that would result by end of the century from a drier Caribbean region, according to the report.
FAO stressed, however, that the most pressing need is for countries to develop strong national initiatives. According to the report, policy-making and planning related to drought is hindered by weak governance, lack of finance and poorly coordinated land management.
“These can be overcome by strong political will that encourages participation in policy and planning processes by all actors in the social strata, enabling the sustainable development of water supplies to face the upcoming challenges,” Mr. Ford said.
