Abstract Context A variety of processes, such as urbanization and development projects, can degrade connectivity in habitat systems, presenting significant threats to species persistence. Effective mitigation depends part on knowledge about where when landscape changes may occur well how respond the landscape. Objectives spatial decision support framework for informing planning efforts involvin...

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...

BACKGROUND Our study analysed the vulnerability of the useful Agave species of the Tehuacán Valley, Mexico, considering ecological, cultural and economic aspects, and management types. We hypothesized that management intensity is proportional to the degree of risk of a species in order to decrease its vulnerability. METHODS Distribution of Agave species was monitored in 36 types of plant asso...

When natural resources are exploited, environmental costs and economic benefits are often asymmetric. An example is apparent in the environmental impacts from fossil fuel extraction by hydraulic fracturing. So far, most scrutiny has been focused on water quality in affected aquifers, with less attention paid to broader ecological impacts beyond individual drilling operations. Marcellus Shale me...

This study systematically identifies, characterizes, and critically evaluates community-level climate change vulnerability assessments published over the last 25 years (n=274).Wefind that while the field has advanced considerably in terms of conceptual framing andmethodological approaches, key shortcomings remain in how vulnerability is being studied at the community-level.We argue that vulne...

iran stands in one of the most disastrous areas in the world and is exposed to different huge and horrible disasters. its settlement on the europe-asia fault makes iran a seismic region. climatically, iran is part of the afro-asian belt of deserts. the lut desert, which has been called the hottest place on earth, is settled in iran and the climate changes have led to considerable increase in fl...

Social and ecological vulnerability to disasters and outcomes of any particular extreme event are influenced by buildup or erosion of resilience both before and after disasters occur. Resilient social-ecological systems incorporate diverse mechanisms for living with, and learning from, change and unexpected shocks. Disaster management requires multilevel governance systems that can enhance the ...

Abstract Vulnerability research and ecological risk assessment of coastal environment are great significance for the temporal spatial evolution process trend zone. In this paper, using 4-phase GF-1 remote sensing data, landscape fragility index artificial disturbance intensity Shanghai section north bank Hangzhou Bay calculated, variation characteristics response to human activities analyzed.
