In urban areas, which factor is likely to increase the occurrence of landslides?

Urbanization is a key factor that increases the occurrence of landslides in urban areas. As cities expand and develop, natural landscapes are often altered significantly. The construction of buildings, roads, and other infrastructure can destabilize slopes and alter drainage patterns, which in turn can lead to an increased risk of landslides.

When land is developed, vegetation that stabilizes soil is often removed, leaving the ground more susceptible to erosion and collapse. Additionally, urban drainage systems may not be designed to effectively manage heavy rainfall, leading to water accumulation that can saturate the soil and trigger landslides. Overall, urbanization tends to disrupt the natural balance of the environment, which can make landslides more likely to occur, especially in areas with steep terrain or vulnerable soil conditions.

In contrast, infrastructure improvement usually aims to enhance support and stability, pollution control measures might improve environmental quality, and green spaces often contribute positively by providing vegetation that helps stabilize soil and reduce erosion risks. These factors typically work toward mitigating landslide risks rather than increasing them.
