Climate change impact on extreme flood occurrence and flood-related damage to the Primorye Region agriculture
IOP conference series(2021)
摘要
Research indicates that climate change aggravates extreme weather events resulting in flooding or soil waterlogging. Damaging abiotic stress imposed by flooding affects crop production negatively. Recently, floods, adversely affecting regional agriculture, occur in the Primorye region yearly. However, available statistics and research on flooding and its consequences for the region are fragmented and scarce. Based on meteorological data of temperature (1889 - 2019), along with annual (1911 - 2019), monthly, and daily (summer months 2015 - 2019) precipitation data in the Primorye region, this research aimed to grasp the exact situation in flooding events occurrence. The results demonstrated a significant increase in the mean annual temperature and extreme precipitation events. Further, the study discussed the deficiencies in the existing system of flood damage assessment and loss compensation. Deriving from the experience of the Federal Research Center of Agribiotechnology of the Far East named after A.K. Chaika (Ussuriisk), the study attempted to estimate the multifaceted negative economic and environmental impact of flooding events on crop production, including flooding influence on land fertility, the effect on pests and disease manifestation, impact on the crop seed quality. The results call for the further robust investigation of the structure (both tangible and intangible) and scale of flooding effects on regional agriculture and add-up to the knowledge base on the topic.
