Land use land cover change and climatic
impacts

 

Land use land cover change (LULCC) plays an important role in the climate system. Impacts of LULCC can be observed at all spatio-temporal scales. LULCC results in the modification of both biogeophysical and biogeochemical properties of the land and atmosphere. Examples of biogeophysical characteristics can be leaf area index (LAI), surface roughness and albedo, while biogeochemical could be the carbon and nitrogen budgets. Changes in these properties eventually modifies weather and climate.

It is found that LULCC, related to deforestation, reforestation, afforestation, urbanization, and agricultural activities, can both increase and lower the long-term maximum temperature over a region by changing energy partitioning (latent vs. sensible energy flux). LULCC also changes timing and location of convection and amount of precipitation. These impacts can be observed at the meso-, regional-/sub-continental scale. In addition, LULCC may also remotely impacts sub-continental scale climate. However, it needs further investigation
