“…Moreover, ecological vulnerability evaluations can be combined with ecological security, pollution management, disaster resistance and insurance, and also provide a theoretical basis and reference for the development of the regional environment. Ecological vulnerability evaluation has developed rapidly in recent years, and many theories and methods have been proposed, such as the multi-index comprehensive evaluation method (Zhou et al 2011;Duguy et al 2012), the fuzzy evaluation method (Farshad et al 2013;Aryafar et al 2013), the artificial neural network evaluation method (Dzeroski 2001;Kia et al 2012), the landscape evaluation method (Kangas et al 2000;Antonio et al 2003;Salvati et al 2013), the analytic hierarchy process (AHP) method (Huang et al 2010;Song et al 2010), and the principal component analysis method (Khan 2012). GIS and remote sensing technologies have become powerful tools for index acquisition and spatial distribution mapping for ecological vulnerability studies (Babiker et al 2005;Saidi et al 2010; Bagdanavičiūt_ e and Valiūnas 2013).…”

Methods and applications for ecological vulnerability evaluation in a hyper-arid oasis: a case study of the Turpan Oasis, China

et al. 2015

The Turpan Oasis is a typical fragile environment that lies in an arid region of eastern Xinjiang and is affected by natural conditions and human activities. The severity of the land degradation and desertification in this area is increasing; therefore, ecological vulnerability evaluations are important for environmental management of the region. In this study, theories and methods of evaluating ecological vulnerability and the typical characteristics of ecological vulnerability were summarized. By combining the environmental characteristics of the research area and the driving factors of ecological vulnerability, a multilayer vulnerability evaluation index system was built, and a pressure-state-response model was established to evaluate the ecological vulnerability. GIS and remote sensing technologies were applied to extract each index and create a spatial distribution map of vulnerability. The results showed that the vulnerability index values ranged from 3.08 to 6.59, with an average value of 5.19. Regions with moderate vulnerability accounted for 81.85 % of the total area, whereas regions with light and serious vulnerability accounted for 4.19 and 13.95 % of the total area, respectively. Thus, more than 80 % of the area had moderate vulnerability, and nearly 14 % of the area had serious vulnerability. The degree of vulnerability increased from east to west, and the ecological vulnerability in the inner oasis was significantly lower than that in the outer oasis. The key factors for ecological restoration and reconstruction are to control desertification and to ensure ecological water use to the greatest extent.

“…Vulnerability assessment frameworks as a policy tool identified not only the specific areas needing immediate attention but also the hotspots in which efforts could be made to reduce vulnerability to anticipated climate change impacts [3,23,25,26]. Undertaking this propensity will allow us to identify particular measurements for constructing resilience when coping with the disturbance and impacts [3,26,27].…”

A Synthesized Vulnerability Assessment: Case Study of Biophysical and Social Vulnerability in Taitung County, Taiwan

Abstract. Strategies and action plans for reducing climate-related disaster risk can be pursued through mitigation and adaptation. In the last ten years, extreme climate events have severely caused flash floods, debris flows, landslides, etc. and have damaged many sectors, including agriculture, infrastructure and health. Since climate change is expected to have continued effects on social functioning and human development, this study proposes a vulnerability assessment framework combining both biophysical and social vulnerability and further carries out synthesized vulnerability analyses to identify vulnerable areas at the county level. Because of its geographical, geological and climatic features, Taiwan is susceptible to earthquakes, typhoons and numerous induced disasters. In many areas of Taiwan, potential hazards include debris flows and flash floods, but these problems are particularly severe in Taitung County. Moreover, the impact of climate change will further cause severe damages and disasters. Therefore, an urgent task for Taitung County is to establish a vulnerability assessment framework as a policy tool to identify not only the regions needing attention but also the hotspots in which efforts could be made to reduce vulnerability. To analyze the biophysical vulnerability of Taitung, this study examined hazards in seven maps from Taiwan's National Science and Technology Center for Disaster Reduction (NCDR) and made some adjustments according to local characteristics. Statistical data from the NCDR regarding social vulnerability were also used. Finally, GIS overlaying technique was used to perform a synthesized analysis of biophysical vulnerability and social vulnerability for each township.

This study uses biophysical vulnerability and social vulnerability data from Taiwan's National Science and Technology Center for Disaster Reduction (NCDR) to assess the vulnerable areas in Hualien County and Taitung County (Hualien-Taitung Area). The most vulnerable townships are Yanping and Chenggong townships in Taitung County, and the least vulnerable townships are Fuli, Jian, Yuli, Shoufeng and Fenglin townships in Hualien County. The severity of potential impacts to townships in Taitung County is greater than that to townships in Hualien County. In the context of climate change, the Hualien-Taitung Area must develop policies that prioritize policies and strategies for hotspot townships. Furthermore, the Hualien-Taitung Area should integrate long-term cross-boundary policies and strategies to lobby for increased funding from the central government. Moreover, cross-boundary resource integration and regional adaptation strategies should be merged to help the Hualien-Taitung Area move toward sustainability.
