Managers charged with maintaining self-sustaining populations of native wildlife in urbanizing areas can protect habitat reserves and encourage development styles that minimize negative impacts on wildlife. Unfortunately, few data are available to guide these activities with respect to bird conservation. Studies are needed that determine principles of reserve design and development pattern that...
Urbanization is an important process in the development of human society. The more developed countries have already achieved a high level of urbanization and have entered a stage of mature urbanization. The less developed countries are just accelerating their pace of urbanization and are in a stage of expanding urbanization. The number of urban population in the poor and less developed countrie...
With a steady increase in impervious surfaces due to urbanization Korea, there is growing burden and an urgent need fund better management of nonpoint sources pollution stormwater. A prerequisite for securing the necessary financial resources determination basic data accurate calculation as basis estimating costs source control billing stormwater utility fees. This requires extraction landcover...
In the past, immunization programmes have focused primarily on rural areas. However, with the recognition of the increasing numbers of urban poor, it is timely to review urban immunization activities. This update addresses two questions: Is there any need to be concerned about urban immunization and, if so, is more of the same kind of rural EPI activity needed or are there specific urban issues...
Multi-objective optimization linked with an urban stormwater model is used in this study to identify cost-effective low impact development (LID) implementation designs for small urbanizing watersheds. The epsilon-Non-Dominated Sorting Genetic Algorithm II (ε-NSGAII) has been coupled with the US Environmental Protection Agency’s Stormwater Management Model (SWMM) to balance the costs and the hyd...
Tropical rainforest regions are urbanizing rapidly, yet the role of emerging metropolises in driving wildlife overharvesting in forests and inland waters is unknown. We present evidence of a large defaunation shadow around a rainforest metropolis. Using interviews with 392 rural fishers, we show that fishing has severely depleted a large-bodied keystone fish species, tambaqui (Colossoma macropo...
