Haitians are noticing climate change impacts on extreme weather and agriculture

Posted on 18 December 2015 by John Abraham

A former student of mine, Luke Hacker formed an organization called Simply Love, which works in Haiti to support educational and agricultural growth in the country. Through this group, I was introduced to an agricultural expert who relayed this personal story about environmental impacts on the island. 

The story below is from Zacharie Bien-Aime, Agronomist, Local Technique Agent for the United Nations.

Since I was a child, I was taught that there are two rainy seasons. One extends from April to June and the other from October to November. As Haitian agriculture is dependent on rain for irrigation, farmers begin with soil preparation during the month of February to be ready to plant when the first rainfall begins in April.

For some time, I have observed changes in Haiti’s climate. Extreme weather conditions alternate between severe drought in the dry season and high rainfall during the wet season. In northwest Haiti where I work, we have just undergone four months of consecutive drought. Peasant plantations have lost most of their harvest because the crops cannot survive without rainfall. The rivers and natural water sources are dry resulting in a food crisis in the local communities. 

For more than a month we have observed the presence of seaweed along the coast and experts claim that this is the consequence of climate change. The presence of this seaweed has serious repercussions for the fishing and tourist economy of these regions and also can present concerns to the health of the local population.

All of this is the consequence of environmental degradation. The Haitian people don’t have access to other affordable energy resources so businesses and families use primarily charcoal. This has led to severe deforestation across the entire country. According to the records available in the archives of the Ministry of Environment, the vegetation coverage in Haiti is less than a 1.5% as of 2015.

In the agricultural sector of Haiti, climate change has caused a yield reduction of our principal crops of rice and maize. Also acceleration of soil erosion under heavy rain has led to a decrease in the fertility and productivity of the soil. Regarding water resources, climate change has increased the risk of flooding and prolonged drought. Longer periods of droughts cause an increase in food insecurity and many other conflicts where consistent use of water is needed.

Given these obvious impacts to agricultural resources and natural water resources, it is important to make the issue of climate change a national priority to be included in the political agenda of policy makers and NGOs in Haiti.Climate change is no longer a myth; it is a reality that we will have to deal with for many decades.

  1. I happened to have spent one year in the Carribean for some projects (related to regional seismicity and the production of a website including a new seismicity catalog). Although this is not my main area of expertise, I may add some points :

    - drought conditions this year were experienced throughout the entire Carribean islands. It rained while it should have been dry, and the next months were very dry while it should have rained (even in July or August). My fellow hydrogeologist colleagues were actually worried about the river levels, and the state representative in Guadeloupe actually declared a drought state and forbade car cleaning and similar actions. These islands usually have several meters/year of rain, and the deficit until September was quite noticeable. 

    - about seaweed, it appeared first in 2011 and arrived in large amounts in 2012. People from the french DEAL (Environment direction) in GUadeloupe tracked the seaweed back to its birth zone using satellite images ; it appears that a second seaweed zone is appearing near Brazil, where it is fueled by all the nutriments carried by the rivers since the forests are cut and the soil is washed away, by the Sahara sand carried by winds, and - more to the point of this blog - increasing water temperatures. It is a real plague : the beaches are covered with huge amounts of rotting seaweed whose stench is unbearable (you can easily imagine the effect on tourism) ... 

    The only source I have is in french (unfortunately) : 


    but at the end of the document some other sources are listed
