By combining the concepts of environmental stress, state susceptibility and environmental crisis, “Security Diagram” (SD)
provides a quantitative approach to assessing environmental change and human security. The SD is a tool that clearly presents
in a diagram the security situation of a population or region affected by a particular environmental crisis. Its underlying
concept emphasises that the higher the level of environmental stress and socio-economic susceptibility, the higher the probability
of the occurrence of crisis. Focusing on drought, this study analyses the susceptibility of case study regions in India, Portugal,
and Russia from a socio-economic perspective. A conceptual framework of socio-economic susceptibility is developed based on
the economic development theories of modernisation and dependency. Fuzzy set theory is used to generate susceptibility indices
from a range of national and sub-national indicators, including financial resources, agricultural dependency and infrastructure
development (for economic susceptibility), and health condition, educational attainment and gender inequality (for social
susceptibility). Results indicate that socio-economic susceptibility over the period 1980–1995 was highest in India, followed
by Russia and (since 1989) lowest in Portugal. Globalisation is likely to contribute to changes in the level of socio-economic
susceptibility over time. Moreover, specific social and economic structures unique in each country (e.g., the role of women
in society in India, the socialist legacy in Russia) may explain differences in susceptibility between the case study regions.

Abstract This paper sets out an examination of natural disaster amongst small island developing states (SIDS), and presents a framework for assessing the interaction of global pressures and local dynamics in the production of human vulnerability. Change at the global level is found to be a source of new opportunities as well as constraints on building local resilience to natural disaster. Much depends on the orientation of the state in global economic and political systems. The United Nations is a key global actor with relevance to shaping vulnerabilityin island states, and the impact of the UN Decade for Natural Disaster Reduction is reviewed. It is concluded that this is a critical time for SIDS which must contend with ongoing developmental pressures in addition to growing pressures from risks associated with global environmental change and economic liberalisation that threaten their physical and economic security. 相似文献
