因應氣候變遷水資源短缺情境下之水稻田灌溉策略 - 論通氣式及乾濕交替式水稻栽培策略

Abstract

水是生命和農業之源，氣候的快速變遷導致水的不足或過多，非但形成水文災害，也造成農業生產及糧食安全危機。如何針對氣候變遷水資源短缺情境研擬因應解決策略，不單是農業問題，更是關乎人類生存與生活的重大議題。本文以臺灣最重要的糧食作物水稻作為藥引，勾勒可行的水稻田灌溉策略輪廓，期以識者迴應以更宏遠的糧食安全通盤考量，以健康、富麗、安全願景的實現讓國人從此過著幸福快樂的日子。 Water is essential for life, for agriculture. The potential threats of water shortage or flooding projected from rapid climate change are very likely raising severe hydrological hazard in many parts of the world. The agricultural production is expected to be affected and so is food security. The impacts yielded from the scarcity of water are among the prospects of climate change need to be carefully deal with, and the related issues are not simply agriculture-oriented but to all aspects of human living. We try to focus on rice production and use it as an example to review and discuss the techniques and strategies suitable for water- / irrigation-saving purpose in response to climate change. We do hope that the important points mentioned in the paper would help to reduce the increasing socio-economic and ecological disturbances and risks on Taiwan, though they are great challenges.
