Abstract:

Livestock snow disaster is one of the most serious natural hazard-related disasters with long duration and wide influences in pastoral regions during winter and spring, which can cause a large number of livestock deaths and injuries. It has seriously threatened and restricted the production and high-quality development of animal husbandry in pastoral regions, with increasing uncertainties in its risk under climate change. Based on the natural disaster system theory, this study examined the theoretical framework of livestock snow disaster formation mechanism and risk assessment, and systematically summarized the progress of relevant research and methods in view of hazard, disaster formative environment, exposure, and risk assessment, along with identifying existing questions. Finally, future research directions of livestock snow disaster are proposed as follows: 1) Enhance the study on the estimation of grass height and the accuracy of retrieving snow depth. 2) Deepen the research on the physical process and mechanism of snow distribution and the coupling risk analysis of multi-hazards and disaster formative environment. 3) Strengthen the study on the spatiotemporal changes of livestock exposure. 4) Strengthen the study on the role of hypoxia environment on the formation mechanism of livestock snow disaster. 5) Promote the cost-benefit analysis of mitigation measures of livestock snow disaster. 6) Improve the study on quantitatively assessing livestock snow disaster risk in the context of climate change, as well as interdisciplinary research.

Key words: livestock snow disaster, mechanism, risk assessment, hazard, disaster formative environment, exposure
