Most Chinese cities face a series of 'urban diseases' or problems during rapid urbanization, and of which urban precipitation and subsequent water-logging is a severe hotspot.
Due to severe shadowing, hotspots, and so forth, the destination may be out of the coverage area of the source.
Until 2007, no intervention had been implemented to reduce the risk of exposure for local residents living at these two severe dioxin hotspots.
Da Nang Airbase (in the Central of Vietnam) served as a bulk storage and supplies facility for AO and other herbicides during the Vietnam War (the Operation Ranch Hand 1961 1971) and is currently one of the three most severe dioxin hotspots in Vietnam (4– 7).
Even worse, household shrinkage was much more severe in "biodiversity hotspot countries" than in nonhotspot countries, as designated by the nonprofit Conservation International, headquartered in Washington, D.C. "There is no question that the number of households has an impact on the environment," says population policy researcher John Bongaarts of The Population Council in New York City.
But environmental flow requirements, especially when combined with other competition for water resources, can create geographic hotspots of severe water scarcity.
For example, Nairobi-based BRCK offers rugged, portable, affordable Wi-Fi hotspots to address the severe consequences of unreliable Internet on a growing economy.
Violation of this assumption leads to a severe underestimation of the null distribution of hotspot sizes and to detection of many spurious hotspots, as shown by Breitling et al. (2008) in the reanalysis of the Wu et al. (2008) data and illustrated in the simulation study and examples below.
In urban areas, such as the country's capital of Port Moresby - a TB hotspot - there is a severe lack of proper housing and infrastructure, meaning TB spreads quickly and aggressively.
The charity's latest analysis of data from the crisis shows that the number of acutely malnourished children under five — almost a fifth of whom have "severe acute malnutrition" — are living in cholera hotspots.
