Analysis of Environmental Vulnerability Using Satellite Imagery and Geographic Information System in Coal Mining Area Planning at Banjar Regency

Abstract

t. It has been done research of environmental vulnerability degradation in coal mining area planning using satellite imagery and Geographic Information System. Vulnerability of environmental degradation is the condition of areas that has potential to damage the environment because of human activities or activity that has potential to cause environmental impacts. Monitoring of environmental degradation can be done to determine the ecological vulnerabilities so as to predict and overcome the future events. The development of remote sensing technology and geographic information systems can facilitate the spatial analysis especially environmental degradation. This research was done to map the vulnerability of environmental degradation in coal mining area planning in Banjar regency and classify environmental damage in the area. The analysis based on scoring and weighting of each index resulting ecological vulnerability index (EVI). The results of the overlay and weighting using weighted summation model’s method in coal mining area planning was plotted into four types of zone, i.e., appropriate exploitation zone, optimized exploitation zone, needs to monitoring exploitation zone, and recommended not to be exploitation zone. Thus, the classification of environmental damage in the coal mining area planning of which are moderate to severe erosion, surface runoff in the watershed, moderate salinity resulting in soil degradation, vegetation does not grow well and loss of recharge area.
