Pollinator-plant relationships are found to be particularly vulnerable to land use change. Yet despite extensive research in agricultural and natural systems, less attention has focused on these interactions in neighboring urban areas and its impact on pollination services. We investigated pollinator-plant interactions in a peri-urban landscape on the outskirts of the San Francisco Bay Area, Ca...
• The role played by the state as a land market regulator in urban areas with natural vulnerability to flooding; as a producer of urban land and housing; and as a builder of defenses against flooding. • Impacts on the land market of flooding and built defenses as well as access to urban land for different population sectors; land value increases and decreases in urban areas according to floodin...
In disaster studies, vulnerability is used to denote “the susceptibility or potential for harm to social, infrastructural, economic and ecological systems” (Pine, 2009, 136). As the nodes of critical systems of human artefacts, urban areas are vulnerable to natural hazards, and suffer losses from disasters. The vulnerability of urban areas is triggered by historical, social, political and physi...
Despite many scholars in various domains including scientific, academic, professional and political fields talking about “Islamic city” and “Islamic ideal city” (Utopia), there is not a specific definition for “Islamic city” based on sacred Islamic texts. In other words, a variety of definitions and attributes of the “Islamic ideal city” are spread in texts based on different backgrounds and st...
Background and Objective: In the process of urban development, many agricultural and peri-urban agricultural land have been changed. On the other hand, the location and development of urban areas in many cases has led to ignoring natural hazards and natural hazards from threats It is the security of cities, one of the most important of these natural hazards is the earthquake. The purpose of thi...
Urban Ecology has come to the forefront of ecological studies in an attempt to further understand what patterns of biodiversity are present within urban environments. Urban Ecology looks to use the many principles of ecology and apply them to the ever expanding cityscape to understand the roles the physical environment in urban landscapes play on species assemblages (Pickett et al. 2008). Citie...
Urban trees play a key role in mitigating urban heat by cooling the local environment. However, benefit that can provide is influenced differences species traits and site-specific environmental conditions. Fifteen dominant tree parks from Mexico City were selected considering physiological (i.e., transpiration stomatal conductance) aesthetic morphological characteristics. Species’ performance w...
