Impacts of LULC on Climate Change

Rakesh Kumar Verma

Abstract


Drastic changes can be observed in LULC (land use and land cover) in the last few decades in the hilly region of Uttarakhand, due to the unexplored potential of its geographical area, resources and human technological prowess. The fate of the this great natural resource and an ecologically sensitive region is getting endangered due to extreme poverty and migration of people, which in turn is leading to unhindered exploitation of the resources without taking into consideration of the natural regeneration and ecological balance. The rapid pace of urbanization can be seen in the hilly towns which are posing a great threat to the ecological balance as the construction of housing, road, dams etc. is causing imbalance in the ecological sustainability of the region. Himalayan ecosystem is a kind of fragile environment which is more susceptible to these land use, land cover changes and its impacts on local climate. For the future prediction of Himalayan ecosystem and its sustainable utilization, it becomes a key importance to know its natural characteristics, its extent and location, predictability, sustainability and limitations of various LULC changes. Increased susceptibility to the LULC changes always provides a platform to the natural disasters and associate damages to the nation. The main feature of concerned are the river basins, snow cover and forest cover.
In this review paper, basically an attainment to associate the LULC changes to the climate change. Over a few decades, significant population growth, human migration, accelerated socioeconomic activities have boosted environmental changes. The climate impacts of these land use and land cover changes can be found in regional, local and global trends in modern atmospheric temperature records and other relevant climatic indicators. It becomes over prime aim to detect the land use and land cover changes with great accuracy at an appropriate scale and in a timely manner, so we can better understand its impacts on climate and can be able to predict its future responses to climate and measures. National Research Council (NRC 2005) has recommended the broadening of the climate change issue to include LULC change processes as an important climate forcing. Regional climate impacts are also associated with the global climate, so it becomes a tremendous job to assess the regional behavior of climate on the basis of land use and land cover changes.
This review paper attempts to understand the impact of the landuse change and land cover depletion on the climate and ecology of the Himalayan Region.
