Desertification Change Analysis Study Using Multi-Temporal Awifs Data: Uttarakhand State
Journal Title: Universal Journal of Environmental Research and Technology - Year 2016, Vol 6, Issue 2
Abstract
The ecosystem in arid, semi-arid, dry sub-humid region appears to be undergoing degradation processes generally described as desertification. The Himalayan region in India is most susceptible to the processes of desertification due to its very fragile and sensitive ecosystem. Change detection study on desertification was conducted on 1:0.5 million scale using IRS-IC and Resourcesat-2 multi-temporal data for the years 2003-2005 to 2011-2013. It was found that there was an increase of 1.25 percent in the desertification area in the state during the study period. A significant increase was observed in vegetation degradation i.e. from 10.20 percent to 11.30 percent. The degradation under settlement also increased from 0.19 percent to 0.30 percent during 2003 to 2013, respectively. The results show that highest vegetal degradation was observed in scrub lands i.e. 1.01 percent followed by 0.14 percent in the forest class. It was also observed that area affected by water erosion and frost shattering show no change during the study period.
