Salt-Water Intrusion Beginning To Rot Rice Crops In Guyana As Sea Levels Rise
GEORGETOWN, Guyana, Wednesday August 15, 2018 (IPS) – Mikesh Ram would watch his rice crops begin to rot during the dry season in Guyana, because salt water from the nearby Atlantic Ocean was displacing freshwater from the Mahaica River he and other farmers used to flood their rice paddies.
The intrusion of salt water into the rice paddies had been happening off and on for the past 10 years, and he, like many other rice farmers in Regions 4 and 5 of Mahaica, Guyana, had sustained periodic financial losses due to the ocean overtopping the 200-year-old sea walls erected as barricades to the sea. And while 2015 was an unusually good year for Guyana’s rice harvest, the following year, 2016, saw a 16 per cent drop in production.
Though the fall-off in production that year could not entirely be attributed to the salt water intrusion, expert sources say this was part of the problem. The United States Department of Agriculture Foreign Agricultural Service’s Commodity Intelligence Report notes that reduced rice production “was due to myriad problems including drought, water rationing, salt water intrusion, lack of crop rotation, less fertiliser input, and slower and lower returns to farmers.” It added that for the first rice crop of 2016, “about 20 per cent was affected by drought and another 15 per cent had salt water intrusion on fields.”
The rice-growing regions of Demerara-Mahaica and Berbice-Mahaica are particularly vulnerable to the impacts of climate change, located as they are six feet below sea level on Guyana’s Atlantic north coast.
