Mortality from extreme heat is a leading cause of weather-related fatality, which is expected to increase in frequency with future climate scenarios. This study examines the spatiotemporal variations in heat-related health risk in three Midwestern cities in the USA between the years 1990 to 2010; cities include Chicago, Illinois, Indianapolis, IN and Dayton, OH. In order to examine these variations, we utilize the recently developed extreme heat vulnerability index (EHVI) that uses a principal components solution to vulnerability. The EHVI incorporates data from the US Decadal Census and remotely sensed variables to determine heat-related vulnerability at an intra-urban level (census block group). The results demonstrate significant spatiotemporal variations in heat health risk within the cities involved. 相似文献

The Western Ghats constitute one of the three biodiversity hot spots in India, which is under constant threat from various
quarters. Among the several anthropogenic causes, fire is one of the important anthropogenic factor, which plays a pivotal
role in vegetation succession and ecosystem processes. It is very important to understand the ecological changes due to fire
and other anthropogenic factors for conservation and management of biodiversity. Because of its synoptic, multi-spectral and
multi-temporal nature remote sensing data can be a good source for forest fire monitoring. In the present study, an effort
has been made to monitor the burnt areas using March 2000 and 2004 IRS LISS — III data. The study revealed that an area of
2.15 km2 and 4.46 km2 was affected by fire in 2000 and 2004 respectively. Repeated drought, followed by mass flowering and dying of bamboo accelerated
the spread of fire from ground to canopy in areas with high bamboo density. 相似文献
