The correct answer is D. Desertification decreases the amount of crop produced.
Explanation
Desertification is the process through which fertile lands lose their productive capacity until they become naturally unproductive and desert lands. Desertification can occur due to natural processes or human activities such as deforestation, monoculture, bad agricultural practices, irresponsible water management, overgrazing, among others. Additionally, if desertification occurs in a previous fertile land that was used for crops it is common the production of crops decreases as soil that has gone through this process losses minerals, water, and nutrients that are necessary to grow crops. So, the correct answer is D. Desertification decreases the amount of crop produced.
