The Impact and The Adaptive Strategies of Global Climate Change on Agricultural Production

Abstract

氣候變遷對農業生產已知會造成相當大的衝擊，唯目前國內與此有關之研究仍十分有限。一般說來，溫度提昇對C4型之作物有正面的影響。而二氧化碳濃度之增加則有利於對C3型之作物之生產。對花卉、蔬菜等短期作物而言，氣候變遷對其影響較小。對果樹而言，高二氧化碳濃度、高溫也有利於生長。為了因應未來對糧食的需求，仍有必要推動有關氣候變遷方面的研究。 Agricultural production is known to be affected by climate change. However only limited studies are conducted in Taiwan. In general, higher temperature has positive impact on C4 crop species. Elevated CO2 may also be beneficiary to C3 crop species. Shorter-season flowers and vegetable crops are some what climate change-independent. Tropical fruit trees seem to be more responsive to elevated temperature and CO2. However, for meeting the demand in food need in the future researches related to climate change are needed
