| The burgeoning populations of this area is contributing to its desertification by clearing forest for agriculture as well as for firewood. |
| This puts enormous pressure on the environment, contributing to deforestation and desertification in these countries. |
| Pollution, erosion, desertification, increased rates of extinction and more can all be traced back to us. |
| This is because trees fight greenhouse emissions, pollution and reduce desertification, droughts, floods and storms. |
| Agriculture was neglected throughout this period, and desertification gradually reduced arable land. |
| It pays poor rural women to plant trees across the country to protect their farms from soil erosion and desertification. |
