NASA datasets offers resourceful Remotely Sensed Images for land-cover and change mapping
The research supplements the risk and disaster management endeavor at the government level to address the concerns regarding agricultural land rehabilitation, food insecurity, transportation, health facilities and compensation for the losses.
The research provides better understanding and evaluation of the changed pattern of food security situation after the disaster
Assess the impacts of Attabad Lake Disaster on agricultural land cover patterns and associated food security in Gilgit Baltistan.
Comparison of pre- and post-disaster agricultural land cover maps.
Assist the concerned risk management authority of the Government of Pakistan.
The project assessed the impact of the Attabad lake landslide disaster on agricultural land cover patterns and associated food security in Gilgit Baltistan, Pakistan. Essentially, this involved agricultural land cover maps, change detection maps, GIS based analysis of Landsat Imagery and statistical analysis of Questionnaires survey to depict the impact of the disaster on livelihood of people. This research also aimed to describe and analyze the changed food security situation that affected the local population due to the landslide.
NASA Earth observation platforms like Landsat TM Imagery, GDEM from ASTER and Google Earth Imagery are resourceful for preparing land cover, change and slope maps. The project would supplement the concerned government authority, the risk & hazard management endeavor as well as private NGOs, INGOs and researchers to understand the geology and environment of the region to cope with the situation of natural disaster & agricultural issues in the future.
