Land Desertification

INTRODUCTION

The process by which fertile land turns to desert is known as desertification. 

“Land degradation and desertification can affect human health through complex pathways. As land is degraded and deserts expand in some places, food production is reduced, water sources dry up and populations are pressured to move to more hospitable areas.” —World Health Organization

 

ACTIVITY

Potential Effects of Desertification Matching Game

Materials: Copies of the handout and scissors // Duration: 10 minutes

  • Students should be in groups of 2 to 4 with one printed copy of the handout (minus answer key) per group.

  • Have the students cut along the bold lines. There should be 12 cards in total per handout.

  • Participants should match the statements that they think are potential impacts of land desertification with one of the “potential impact” cards and match statements they think are not potential impacts of land desertification with one of the “not a potential impact” cards.

  • Go over the answer key at the end.

LESSON

Desertification has accelerated during the 1900s to 2000s due to a multitude of human activities such as over-cultivation and forest conversion, which can degrade the quality of soils in the affected land. This process does not just influence animals living in the area, it can have a major impact on everyone, including humans.
