Wildfires: GIS and Remote Sensing Monitoring and Mangement

Image
  Forests cover 20.55% of total India's geographic area. This large forest area requires proper timely monitoring and assessment as there are various problems that cause forest degradation and affects the ecosystem to a large extent. Forest Fires are one of these problems. As per the report of Forest Sir of India, 50% of the forest land is prone to fire. The risk of forest fire is at an alarming rate in India, so it requires a proper risk assessment and monitoring report. Geospatial data and tools are employed in this field to manage the forest fires in India. Satellite imagery and aerial photography are used in mapping, high-resolution sensors are used to detect the fires. As these forest fires contribute to environmental consequences, we have most recently observed Amazon forest fires and forest fires in Australia, which are devastating, species have been killed, the land has been destroyed, air pollution and many more ill effects have taken into place. So, this is really an impo

Polar Bears: Its inclusion in list of Endangered Species in US

The iconic specie of circumpolar Arctic regions which is known as Polar bears or URSUS MARITIMUS is come under the category of hypo carnivore mammals, considered to be largest land mammals and has become the first mammal species to face the 100% habitat destruction due to global warming. Climate change is the major rival into the lives of polar bears. Starvation, human inter reference and exploitation and global warming led the polar bears to the critical stage where the species have experienced alarming rate of population decline in various arctic regions specially in Canada. In the year 2005, strong voices have raised to protect the Polar bears and it became the big headline at that time in United States. In 1973, the Government of USA has added polar bears to the Endangered species list but with time the studies and reports have shown decline in population of bears So, the authorities have decided to add Polar bears to Threatened species list of ESA.
