Understanding And Predicting Desertification : Researchers Offer New Insights On Arid, Semiarid Landscapes

ScienceDaily (June 5, 2006)

A team of researchers in New Mexico has developed a multi-faceted process to study arid and semiarid landscapes that takes into account the wide range of factors influencing changes that can result in desertification.

Almost 40 percent of the Earth’s surface and 20 percent of the world’s population are found in regions that are under threat from desertification, which can result in the loss of grass and degradation of soil as grasslands are converted into woody-plant-dominated landscapes.

Although many research methods exist to study various facets of this process, more complete understanding of desertification can be achieved by looking back in time at historic legacies, considering environmental factors and studying soil, typography and soil parent material. Also considered is the influence of wind, water and animals as they transport water, nutrients, soil particles, plant litter and seeds. The redistribution of those resources also is weighed in the landscape reorganization.
