    Mulching to control soil erosion in Dominica 2014
    Also available in:
    No results found.

    Natural hazards, such as storms, hurricanes, and heavy rains, directly impact agricultural productivity and production in Dominica, leading to landslides and soil erosion, among others. In order to better mitigate the impacts of these hazards and prevent soil erosion, mulching can be used to protect and conserve the soil, and reduce erosion by water and wind. Mulching is a very simple and beneficial practice where organic material, such as crop residues and weeds, or inorganic material, like plastic sheets, is spread over the soil surface.

    Establishing grass barriers along the contour to reduce water runoff and erosion during heavy rainfall, Grenada 2012
    Also available in:
    No results found.

    The agricultural sector in Caribbean islands such as Grenada is extremely vulnerable to storms and hurricanes. Establishing grass barriers along the contour can help in reducing water runoff and erosion during heavy rainfall. Grass barriers provide erosion control on croplands and offer a cheaper and more sustainable alternative to terraces in areas where soil degradation is highly likely. This system reduces surface runoff by promoting detention and infiltration, diverts runoff to a stable outlet and helps entrapping sediment-borne and soluble contaminants. This practice describes how to establish a grass barrier.

    Soil conservation: Contour ploughing, Grenada 2008
    Also available in:
    No results found.

    Contour ploughing mitigates the impacts of floods, storms and landslides on the crops by reducing soil erosion up to 50 percent, controlling runoff water, increasing moisture infiltration and retention and thus enhancing soil quality and composition. This practice describes contour ploughing and contour beds which can be constructed manually using on farm equipment.
