Wetlands support unique biota and provide important ecosystem services. These services are highly threatened due to the rate of loss and relative rarity of wetlands in most landscapes, an issue that is exacerbated in highly modified urban environments. Despite this, critical ecological knowledge is currently lacking for many wetland-dependent taxa, such as insectivorous bats, which can persist ...
Lake areas in Chinese urban fringes are under increasing pressure of urbanization. Consequently, the conflict between rapid urban sprawl and he maintenance of water bodies in such areas urgently needs to be addressed. An integrated GIS-based analysis system (IGAS) for supporting and-use management of lake areas in urban fringes was developed in this paper. The IGAS consists of modules of land-u...
inappropriate patterns and drastic changes in land-use have caused the severe environmental crisis. therefore, it is necessary to accomplish any plan in relation to establishment of different activities with respect to land capabilities and land-use evaluation thought. in this study, ecological capabilities and the site selection of land uses in babolrood basin, mazandaran province were evaluat...
Nature in cities is concentrated in urban green spaces, which are key areas for urban biodiversity and also important areas to connect people with nature. To conserve urban biodiversity within these natural refugia, habitat restoration such as weed control and revegetation is often implemented. These actions are expected to benefit biodiversity, although species known to be affected by urbaniza...
Urban and peri-urban forests determine different habitat services for biodiversity according to their characteristics. In this study, we relate ecological characteristics of urban and peri-urban forests to forest bird species richness and we assess whether their effect changed over time due to the urban sprawl within the urban region of Milan, Italy. We analyse two periods (1998–2002 and 2010–2...
Urban storm inundation, which frequently has dramatic impacts on city safety and social life, is an emergent and difficult issue. Due to the complexity of urban surfaces and the variety of spatial modeling elements, the lack of detailed hydrological data and accurate urban surface models compromise the study and implementation of urban storm inundation simulations. This paper introduces a Const...
Cities are complex urban systems with dynamic transformations in their socio-economic and environmental dimensions. Several studies have shed light on the fragility of heritage strategies its conservation. The historic landscape (HUL) approach is a new framework adopted by UNESCO to deal heritage. This article aims apply HUL rehabilitation management Beirut neighbourhoods impacted massive port ...
The world's human population is becoming concentrated into cities, giving rise to concerns that it is becoming increasingly isolated from nature. Urban public greenspaces form the arena of many people's daily contact with nature and such contact has measurable physical and psychological benefits. Here we show that these psychological benefits increase with the species richness of urban greenspa...
