Impact of global climate change on land degradation and human action

Abstract

Global climate change of the magnitude and rate seen in the past hundred years is a relatively recent, unfamiliar threat to the conditions of the natural environment and human health. It is one of a set of large-scale environmental changes now underway, each reflecting the increasing impacts of human activities on the global environment. These changes, including: stratospheric ozone depletion; biodiversity loss; worldwide land degradation; freshwater depletion; and the global dissemination of persistent organic pollutants have great consequences for the sustainability of ecological systems, food production, human economic activities and human population health. Changes in climate are recognized as one of the major factors responsible for land degradation affecting sustained development. To ensure sustained development, conjunctive efforts based on a sound understanding of the various factors that bestow to land degradation around the world are required. Climate change deteriorates the soil structure are hard to quantify because of the influence of land use and management, hence further research is this area is required for better understanding of the effect of climate change on soil structure The major components and advances in land change are addressed: observation and monitoring; understanding the coupled system—causes, impacts, and consequences; modeling; and synthesis issue. In most cases, changes in soils by direct impact on human action, on-site or off-site (whether intentional or unintended), are far greater than the direct climate-induced effects.
