Soil conservation: Contour ploughing, Grenada

Summary

Natural disasters in particular the recurrent hurricane seasons seriously impact its agricultural sector, to which the island's economic fortunes are historically linked. The island's vulnerability is further aggravated by its mountainous terrain: over 50 percent of the lands are over 20 degrees, and only 6 percent of the lands are considered flat. One of the local agricultural practices to mitigate the negative consequences of hazards is contour ploughing. Crop row ridges are built by tilling and/or planting on the contour creating hundreds of small dams. These ridges or dams slow water flow, increase infiltration and reduce erosion. Contour ploughing is a highly cost effective and sustainable practice.
