Gabions are metal baskets filled with stones. Gabions act as retaining walls and will mitigate the effects of heavy rainfall, which is accelerating due to climate change. They can be placed in streams and gullies to slow the flow of water and prevent flooding. If the water is not slowed down, the topsoil is washed away and erosion worsens. With the topsoil gone, there are no nutrients left, making the soil unsuitable for vegetation and water absorption. Gabions will hold this and prevent erosion and further degradation. Moreover, the gabion allows water to pass through while trapping soil particles. Where possible, the community should be involved as gabions play a role in protecting their communities and land. Gabions can also be used for coastal protection and slope stability. Sometimes they are also used for aesthetic purposes.
