Monitoring war-generated environmental security using remote sensing: A review

The negative impact humans have on the environment directly affects the environmental security. Over the years, it has been proven that wars make drastic and sometimes unrecoverable environmental damage. Remote sensing has played a main role in providing necessary data for spatiotemporal analysis. This paper reviews remote sensing implementation of war activities for environmental monitoring. This review is timely due to the exponentially increasing number of works published in recent years. This paper's main objective is to locate the papers and find geographic link, sensor use, and environmental degradation type. Following a discussion of remote sensing's capabilities, this overview illustrates numerous environmental damages caused by military operations in various world places. Our study found that wars have a detrimental influence on the ecosystem across the world, with major reasons being forest loss, oil spills, and urban growth. According to the findings, remote sensing, particularly middle-resolution satellite images, is extensively and successfully employed for environmental security monitoring. The rehabilitation of a deteriorated environment should be one of the key areas of future study.
