Effect of Climate Change on Land Degradation

Degradation currently affects 25 % of the land on Earth and 40 % of theagricultural land on Earth. Environmental effects of soil degradation are widespread,including increased soil losses, deterioration of water quality, decline of biodiversity anddegradation of ecological resources and associated values, especially where actual land use isdisrespectful (natural use in circumstances where land is in conflict with the environment.Changes in temperature, wind velocity, and precipitation patterns can affect the production ofplant biomass, land use, land cover, soil moisture, infiltration rate, runoff and cropmanagement, and eventually land degradation. In recent decades, powerful partnerships havebeen seen between global climate change and land loss processes. In order to reliably defineor forecast the effect of climate change on the loss of land, models of climate change and landuse models should be combined with hydrology. Until the first seventies land degradation andgeological process weren't thought of a serious issue in most Mediterranean regions.Traditional agricultural systems were believed to be able to keep those processes undercontrol. So low priority was appointed to research programmes and comes on eroding andconservation, preference being given to the impact of farm machinery on soil structure andcompaction beside the role of organic matter within the soil. To regulate the destruction ofsoil, it is therefore important to have limited and global strategies and regulations. Land useand land cover changes influence carbon fluxes and GHGs emissions that directly alteratmospherical composition and radioactive forcing properties. Land degradation aggravatesgreenhouse gas-induced global climate change through the discharge of CO2 from cleared anddead vegetation and thru the reduction of the carbon sequestration potential of degraded land.The present analysis furnishes effects of climate amendment on land degradation.
