Question
A particular region has experienced increased deforestation. This has led to an increase in soil erosion, which has caused a decrease in the overall soil quality of the region due to the loss of fertile topsoil. Farmers in the area have had difficulty growing crops in the less fertile soil that is left behind, which has negatively impacted the region's economy.
Which of the following solutions would best help reduce soil erosion and improve soil quality in the region?
A.
switching to organic fertilizers and allowing grazing by domesticated animals in fields not currently used for crop cultivation
B.
adding small amounts of phosphate and other chemicals to the remaining soil before planting crops
C.
switching to synthetic fertilizers and using aggressive agriculture techniques such as slash-and-burn farming
D.
increasing the vegetative cover in the region and using sustainable farming techniques such as terrace cultivation

The best solution to reduce soil erosion and improve soil quality in the region would be:
**D. increasing the vegetative cover in the region and using sustainable farming techniques such as terrace cultivation.**
This option focuses on enhancing the natural vegetation, which helps to hold the soil in place and prevents erosion. Sustainable farming practices, like terrace cultivation, can also improve water retention and soil quality over time, making it more conducive to crop growth. In contrast, the other options could either exacerbate soil degradation or are less effective in addressing the core issue of soil erosion.
