Which ecological trade-off resulted when mountain terraces were constructed for agriculture?

💡 Explanation

When terraces are created, the exposed soil becomes vulnerable to erosion due to rainfall and water flow creating 'sheet erosion' because interception of water, especially intense tropical storms, will carry nutrients downstream. Therefore, there increased sediment loads will alter ecosystems. Topsoil nutrient can deplete rapidly after the loss of organic matter unlike others. Downstream ecosystems receiving excess sediment load would be under threat rather then ecosystems changing rainfall pattern which is highly complex compared to local sediment and erosion conditions.
