A
trimming dead branches off the trees on the land
B
putting fences on the land
C
clearing the land of trees
D
building hiking trails on the land
Explanation: 

Detailed explanation-1: -Deforestation for Agriculture Is One of the Top Causes of Soil Erosion. The increasingly high demand of a growing population for commodities such as coffee, soybean, palm oil or wheat is clearing land for agriculture.

Detailed explanation-2: -Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.

Detailed explanation-3: -The soil erosion causes the most damage to the environment so if you don’t take care of it, the environment could be very dangerous. Soil erosion can also make the dirt harder so it could slow down plants to grow. When things start eroding, they fade away because of some kind of force acting on it.

Detailed explanation-4: -Soil erosion removes valuable top soil which is the most productive part of the soil profile for agricultural purposes. The loss of this top soil results in lower yields and higher production costs. When top soil is gone, erosion can cause rills and gullies that make the cultivation of paddocks impossible.

Detailed explanation-5: -The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
