Natural disasters cause serious economic and human losses. Yet there remains ambiguity in the existing literature with regard to their impact on the economy at large. This study re-examines the relationship between natural disasters and economic growth. It aims to contribute to a fairly limited literature on the economy-wide and sector-specific consequences of natural disasters in the short-to-medium term (up to 5 years). Further, it examines whether the disaster impacts are dependent on a country’s level of development. Based on panel data consisting of 102 (29 developed and 73 developing) countries over the period 1981–2015, it looks at the growth effects of four types of natural disasters, namely, floods, droughts, storms and earthquakes that were explored using the system generalised method of moments (GMM) approach. The results indicate that natural disasters have diverse economic impacts across economic sectors depending on disaster types and their intensity. The study confirms the findings of previous studies that the economic impacts of natural disasters are statistically stronger in developing countries. These findings may stimulate the policymakers especially in developing countries to explore the efficacy of viable ex-ante disaster risk financing tools (such as insurance, micro-insurance and catastrophic bonds). This would not only safeguard population and physical assets but also ensure adherence to the sustainable development goals. JEL Classification: Q54, O10

Abstract Older adults, particularly those from low-income communities, are disproportionately negatively affected by natural disasters. As the older adult population grows and natural disasters increase in frequency and intensity, social workers must consider their role in supporting the needs and safety of this population. Social workers practice in varied roles including policy advocate, service broker, and educator, all of which are crucial in disaster management. This systematic review summarizes the literature on the social work profession’s involvement with emergency management with older adults, and identifies gaps. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, authors searched AgeLine, CINAHL Complete, MEDLINE, PsycINFO, and Social Work Abstracts for peer-reviewed publications between January 1, 2009 and March 1, 2020. Examples of the terms searched include social work*, respon*, prepar*, disaster, crisis, emergency, geriatrics and older adults. The initial searches yielded 298 publications. After removing duplicates and screening articles for relevance based on titles and abstracts, 21 publications were retained for full review. A total of 11 articles met inclusion criteria. The body of literature identified was small. The majority of the publications constituted conceptual papers, textbook reviews, and letters to editors requesting greater emphasis on emergency management. Only three empirical studies were identified. Broadly, the publications discussed: (1) policies and resources; (2) needs; (3) capacity across practice settings; and (4) interventions. Findings reveal an underdeveloped area of social work practice, and highlight opportunities for researchers and practitioners to define gerontological social workers’ role in emergency management and detail best practice guidelines.

Abstract. Natural disasters have enormous impacts on human society, especially on the development of the economy. To support decision making in mitigation and adaption to natural disasters, assessment of economic impacts is fundamental and of great significance. Based on a review of the literature of economic impact evaluation, this paper proposes a new assessment model of economic impact from drought by using the sugar industry in China as a case study, which focuses on the generation and transfer of economic impacts along a simple value chain involving only sugarcane growers and a sugar producing company. A perspective of profit loss rate is applied to scale economic impact with a model based on cost-and-benefit analysis. By using analysis of "with-and-without", profit loss is defined as the difference in profits between disaster-hit and disaster-free scenarios. To calculate profit, analysis on a time series of sugar price is applied. With the support of a linear regression model, an endogenous trend in sugar price is identified, and the time series of sugar price "without" disaster is obtained using an autoregressive error model to separate impact by disasters from the internal trend in sugar price. Unlike the settings in other assessment models, representative sugar prices, which represent value level in disaster-free condition and disaster-hit condition, are integrated from a long time series that covers the whole period of drought. As a result, it is found that in a rigid farming contract, sugarcane growers suffer far more than the sugar company when impacted by severe drought, which may promote the reflections on economic equality among various economic bodies at the occurrence of natural disasters.

As a result, it is found that in a rigid farming contract, sugarcane growers suffer far more than the sugar company when impacted by severe drought, which may promote reflections among various economic bodies on economic equality related to the occurrence of natural disasters. Further, sensitivity analysis of the model built reveals that sugarcane purchase price has a significant influence on profit loss rate, which implies that setting a proper sugarcane purchase price would be an effective way of realizing economic equality in future practice of contract farming.
