farming practices that expose topsoil to water and wind often result in which degraded the soil and can ultimately threaten food production

Soil erosion and lost of fertility.

Explanation:

The farming practices that expose topsoil to water and wind often result in erosion of the soil because the wind and water takes particles with them. If water and wind removes the soil particles continuously then the land become barren and lost its fertility which leads to lower production of food crops that  ultimately threaten the food production for the population.
