Sustainable Agricultural Practices: Energy Inputs and Outputs, Pesticide, Fertilizer and Greenhouse Gas Management

永續的農業實施:能量輸入與輸出、農藥、肥料及溫室氣體管理

摘要


二十世紀透過「現代農業」技術的發展,回應了糧食安全的考量。但同時,食品的安全與環境劣化兩大議題卻被犧牲了。近年來的氣候變遷已被認定是肇因於將儲存在化石燃料中的能量釋放到大氣中。現代農業產生的均一產品築基於同質性作物品種、機械化、農藥與肥料的使用等。農業機械直接使用化石燃料為能源,而化石燃料也用於生產農藥與肥料,因此化石燃料是現代農業的主要推手也是造成氣候變遷的重要殺手。本文對利用農業系統作為生質燃料生產與能源供應的可能性進行討論。

The food security issue was addressed by the development of ”modern agriculture” in the last century. But food safety issues and environment degradation were the consequences suffered as a result. Climate change has been recognized as the result of release of stored energy in fossil fuel into the atmosphere. Homogeneous crop varieties, machinery, pesticides and fertilizers are the foundation of uniform commodities in modern agriculture. Fossil fuels are used to manufacture fertilizers and pesticides as well as the energy source for agricultural machinery, thus characterizes modern agriculture. Bio-fuel production and the possibility of the agriculture system as a form of energy input are discussed.
