The management strategy based on the effects of climate change on crop pests

Abstract

目前大家已能接受全球氣候變遷對生態系統會產生重要影響，這結果多數是藉由經度與緯度變化的角度切入研究。雖然如此，但過去百年以來，台灣仍缺乏農業長期變化與空間分布因子的相關研究。有鑑於此，本研究目標包括蒐集往昔科學研究報告所示之農作物有害生物資料，從中分析農業生態系統之中作物有害生物 (病原、害蟲、雜草)與作物、栽培措施及氣候因子的相互關係，建立一個可以預測氣候暖化對有害生物分布影響的管理策略。 It is now widely accepted that global climate change is affecting many ecosystems around the globe and that its impact is increasing rapidly. Many studies predict that impacts will consist largely of shifts in latitudinal and altitudinal distributions. However, the related studies on long-term changes and spatial distribution characteristics of agro-climatic conditions in the past 100 years in Taiwan are still unknown. Accordingly, the present project has following goals: i) to glean available information from the historically scientific papers associated with mainly crop pests of Taiwan; ii) to analyse the relationships among the pests (e.g. pathogens, insect pests, and weeds), crops, cultivated techniques, and climatic factors in agro-ecosystem, and then, to establish a management strategy to predict the effects of climate warming on species distribution of crop pests
