第五章 結論與建議
5.2 建議
1. 物質流結合生命週期評估方法,不像傳統生命週期評估盤查範疇需先行界定,
透過物質流分析方法輔助,使得盤查範疇更具靈活性,然而因國家尺度地理邊 界較大,全國性的統計實際盤查資料曠日費時,本研究水能糧之物質流分析以 現有官方公開全國性統計資料基礎。然而有些資料可能因較難統計調查或不 同單位資料統計方式對應不上,尤其是水能糧交織關係之關鍵參數乃以文獻 或代表性大廠之係數值假設推估而得,雖未必為實際值,但仍具一定的參考性。
根據經費與目標可進一步盤查或實際調查,提升資料精確度。
2. 本研究資源總生產量並不影響資源單位產品環境衝擊和資源之交織係數,兩 者與總衝擊之間的關係為線性,但實際上可能並非如此,隨著產品總量變大之 邊際效應還可以進一步模擬考量之。
3. 本研究對於未來情境設計,需求面為政府模式模擬推估之結果,供給面為政府 之預期推動之政策目標。但政策目標未必有非常細部的規劃因此某些環節只 得自行假設,如非核家園不同機組之發電配比,新興水資源2025 達成率未知 故假設提前達成,糧食假設供需不變。
4. 基於前述幾種可能造成結果偏誤的原因,可進一步探討資料選擇的不確定性,
參數之不確定性,模型模擬之不確定性。對結果的不確定性範圍大者,為可著
重加強精確度之處。
5. 由文獻回顧可知,特殊人文地理條件下將導致資源交織關係有所差異。台灣水 資源以取用地表水為主,能源仰賴進口且電廠多座落海邊,導致水能交織強度 相較國外偏低,並且可能因考量的是全國尺度,使局部極端值無法凸顯,假若 稍微縮小尺度於縣市層級尺度於缺水地區(如離島、中南部地區)將有較高的資 源交織強度。亦或是因能源短缺而興建內陸火力電廠,將被迫使用淡水作為冷 卻水,如高原電廠開發計畫,都將提高資源交織強度。尤其是多個資源同時短 缺的情況,資源交織關係將更加緊密。
6. 本研究旨在呈現不同衝擊類別因資源交織關係造成之跨部門的衝擊轉移作用,
故僅使用中點導向衝擊類別作為評估指標,倘若任何政策組合下,衝擊項分配 不均的情形皆無法避免,若為決策考量,亦能將不同衝擊項予以權重化方便決 策,但跨部門的環境衝擊責任權責區分仍有待探討。
7. 若探討最終需求部門資源需求成長驅動力之影響因子,或能以影響因子作敏 感度分析發現其他影響環境衝擊關鍵參數。此外,若資源調適策略以需求端著 手出發,則建議進一步探討使用端與廢棄端之水能糧交織關係,以評估此調適 策略對其他資源系統的影響。若同時針對最終需求部門若進一步探討產品使 用與廢棄階段的環境衝擊,藉由產品之完整生命週期,亦可以進一步觀察環境 責任的歸屬。
