Soil conservation measures reduce the risk of both:

The correct answer is: a) Floods & landslides.

Soil conservation measures are practices that help to protect soil from erosion, degradation, and loss. They can reduce the risk of floods and landslides by stabilizing the soil and preventing it from being washed away or moved by landslides.

Here are some examples of soil conservation measures:

• Terracing: This involves creating a series of steps on a slope to reduce the amount of water that runs off the land.
• Contour farming: This involves planting crops in rows that follow the contours of the land, which helps to prevent soil erosion.
• Cover cropping: This involves planting cover crops, such as grasses or legumes, between rows of crops. Cover crops help to protect the soil from erosion and improve its fertility.
• No-till farming: This involves planting crops without disturbing the soil, which helps to prevent soil erosion and improve its water retention.
• Strip cropping: This involves planting crops in alternating strips of different crops. This helps to prevent soil erosion and improve the efficiency of water use.

Soil conservation measures are important because they help to protect the environment, improve agricultural productivity, and reduce the risk of natural disasters.
