Establishing grass barriers along the contour to reduce water runoff and erosion during heavy rainfall
The agricultural sector in the 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.
