Resilience is increasingly used as an approach for understanding the dynamics of natural disaster systems. This article presents the origin of resilience and provides an overview of its development to date, which draws on the wide literature on ecological science, social science, social-environmental system and natural hazards. From a geographic perspective, the model of disaster resilience of ''Loss-Response'' of Location (DRLRL) was created and disaster resilience was defined from three dimensional mode, which focused on the spatial, temporal scale of resilience and attributes of hazard-affected bodies. A geographic approach was put forward to measure the disaster resilience, including two properties of inherent resilience and adaptive resilience and a case study was implemented in order to validate this approach. This perspective would offer greater potential in application of resilience concept, especially in the process of integrated risk management and disaster recovery.
Based on the previous research findings about resilience, this study focused on the differences between resilience and adaptation from an agricultural drought case study in southern China. A conceptual variation between resilience and adaptation was explored to understand the distinction between resilience and adaptation. In fact, both are attributes of hazard-affected bodies and have connections and differences. Resilience pays more attention to the short-term response to loss (potential) during and post disaster, while adaptation places stress on system's response to disaster risk before disaster, loss or impacts in-and after disaster in the long term in order to reduce vulnerability and enhance resilience. Land use and crop structure change, land policy change and labors turnover present the detailed differences between resilience and adaptation in the case study. Deficiencies of human resources, technology and policy in adapting to disaster risks were founded and discussed. This perspective would offer a way with greater potential in application of adaptation concept, especially in the process of integrated risk governance and regional sustainable development.
Seasonal water scarcity in southern China has been an issue of concern for many years. The increased frequency of low precipitation in the growing season of rice created a flurry of discussions in the academic and policy arenas. These events severely disrupted the supply of irrigation water for agriculture in paddy field areas and posed a substantial threat to farmers' livelihoods. Within a broader context of accessing farmers' resilience to agricultural drought, this paper focuses on the response mechanisms and adaptive strategies adopted by farming households in three types of areas (Plain, Hill, Mountain) in Dingcheng, Hunan Province. With the increasing drought frequency and the pressure from the demand for livelihood improvement, farmers' response mechanisms have evolved, expanding from short-term adjustments to long-term adaptations, and switching focus from securing reliable water sources to improving irrigation efficiency and diversifying both on-and off-farm productions. The three types of geographic units have different resilience profiles and have developed diverse patterns of adaptive processes that update the conceptual model of Disaster Resilience of ''Loss-Response'' of Location. It presents a temporal dimension to the study of resilience, which is largely missing from the current literature and provides insights into how to enhance farmers' response capacities in the face of agricultural drought in southern China.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
