Trees, grasses, and vegetation can minimize the amount of water infiltrating into the soil, slow the erosion caused by surface-water flow, and remove water from the soil. So decrease in vegetation can cause landslide.

Explanation:
The correct answer is option 'C', which states that decreasing vegetation cover is not an applicable technique to cope with landslides. Here's why:
Construction of Retention Wall:
One effective technique to cope with landslides is the construction of retention walls. These walls are built along slopes to prevent the land from slipping. They provide stability and support to the soil, reducing the risk of landslides.
Implementation of Surface Drainage Control:
Another important technique is the implementation of surface drainage control. Proper drainage systems can redirect water away from slopes, preventing saturation of the soil and reducing the chances of landslides. This technique helps to manage the water flow and prevent excessive erosion.
Hazard Mapping:
Hazard mapping is a crucial step in landslide management. By mapping and identifying areas prone to landslides, authorities can take preventive measures such as land-use planning, restricting construction, and implementing early warning systems. Hazard mapping helps in identifying high-risk areas and implementing appropriate measures to minimize the impact of landslides.
Decrease in Vegetation Cover:
The given statement, option 'C', suggests decreasing vegetation cover as a technique to cope with landslides. However, this is not an applicable technique. In fact, vegetation cover plays a crucial role in preventing landslides. The roots of plants help bind the soil together, reducing erosion and providing stability to slopes. Vegetation cover also absorbs rainfall, preventing excessive water from infiltrating the soil and causing instability. Therefore, decreasing vegetation cover would actually increase the risk of landslides rather than mitigating it.
In conclusion, the correct answer is option 'C' - decreasing vegetation cover is not an applicable technique to cope with landslides. Instead, retaining walls, surface drainage control, and hazard mapping are effective measures to mitigate the risk of landslides.
