Hedgerows/alley cropping to control soil erosion, Jamaica

Summary

Jamaican small farmers implement hedgerow/alley cropping to mitigate the impacts of hydro-meteorological hazards. The hedgerows/alley cropping system is an agroforestry practice, where fast-growing nitrogen fixing trees are planted in rows, and food or cash crops are planted in the space (‘alley’) between the rows. This practice helps to control soil erosion, increases the water-holding capacity of the soil, reduces deforestation, generally improves soil fertility and productivity and diversifies agricultural production. There has been a high acceptance level of this technology in Southern Trelawny, Jamaica where it has been implemented, due to the ease of implementation, its effectiveness in controlling soil erosion and the low financial cost.
