摘要

The water resource is essential to all forms of life and its management is a challenging task under the influence of climate change. Global warming induces the intensification of the atmospheric water cycle, resulting in the more frequent occurrence of severe precipitations and droughts. Adaption actions should be considered and implemented to ensure the sustainable management of water resources. Current practices, including promoting forestation, construction of healthier green infrastructure, verdant coverage on the slope lands, installation of LID facilities and detention ponds, and enhancement of inland storage mechanism for water resource conservation, should continue. The proposed policies balancing water resource consumption/ supply and emphasizing the effectiveness and fairness among various domestic and industrial functions should be enforced. The coordination between central and local governing agencies becomes critical when allocating limited water resources. Public participation should not be ignored during the policy-making process. Moreover, international cooperation through knowledge and technology transfer should be encouraged. Real-time monitoring should be implemented using wireless transmittance to enhance the simulation accuracy and forecasting capability of the management system of water resources. While many advocates emphasize the importance and necessity to mitigate the global warming impact, applicable technologies should be developed and implemented. Immediate actions should be taken to realize the ultimate goal of controlling atmospheric temperature variation with an acceptable range, thus ensuring the sustainable use of water resources.

水為維繫生命的重要物質，在氣候變遷的條件下，水資源管理為一具有挑戰性之工作。全球暖化引發大氣水文循環加劇，導致極端降雨與乾旱發生頻率增加，因此調適行動應儘速落實，以確保水資源之永續經營。目前推動之各項調適作為應持續進行，包括造林、建構完善綠色基礎設施、坡地綠覆蓋、低衝擊開發設施與滯洪池，健全陸域水土保持功能，平衡水資源供需，強化民生及工業用水之效率與公平性等。針對有限水資源之分配，中央與地方主管機關應有完善的協調機制，民眾參與不宜排除於決策過程之外，應用即時無線傳輸技術，以增加水資源管理系統之情境模擬準確性、提升預測能力。當減緩全球變遷衝擊之重要性與必要性不斷被強調的同時，可供應用的調適技術應積極進行研發與應用，相關的行動方案應儘速落實，以實現控制大氣增溫於可接受的範圍內，確保水資源的永續利用。
