The city of Phoenix was built on top of the ruins of canals built by the Hohokam people between 500 and 1450 CE. Deforestation can include clearing the land for farming or livestock, or using the timber for fuel,. The pounding of the soil by the hooves of livestock in ranching, for example, may degrade the soil and augment erosion by wind and water. Over the last few centuries, this has changed dramatically: wild habitats have been squeezed out by turning it into agricultural land. - has been the . land surface temperature data from . The Great Green Wall initiative in Africa has evolved away from the idea of simply planting trees and toward the idea of "re-greening," or supporting small farmers in managing land to maximize water harvesting (via stone barriers that decrease water runoff, for example) and nurture natural regrowth of trees and vegetation. Beginning about 15 000 years ago continental glaciers retreated and sea level began to rise. However, the LSA changes induced by global vegetation greening are still not clear, and contrasting responses of LSA to vegetation changes were . They estimated that there were approximately 3.04 trillion trees in the world.
