農業用水：挑戰

內容簡介

《農業用水:挑戰、科技創新、技術措施(英文版)》圍繞氣候變化的大背景下，我國乾旱缺水加劇，農業用水逐年減少，水資源嚴重不足的現狀。論述和回顧了我國農業水資源開發、利用以及節水農業發展現狀，引入化學節水的概念，結合國內外最新研究進展，從新型化學節水保水材料、製劑和產品的研發、農業節水套用技術和措施，以及新材料對土壤和作物，乃至整個環境的影響效應等多方面、多角度地闡述了化學節水材料農業領域套用的前沿動態和學術成果。

Water resource is one of the most important natural resources that mankind depends on for survival and development, and one of the controlling factors of the ecology and environment. Global water use has been growing at more than twice the rate of population growth in the last century. Moreover, the water scarcity situation is being exacerbated by climate change, especially in the driest areas of the world. Agriculture consumes about 70 percent of all freshwater withdrawn and up to 95 percent in several developing countries. To tackle water scarcity even as the demand for food increases, we must support initiatives to improve water conservation and delivery systems, protect the earth's ecosystems, conserve rain-fed moisture and use water for food production more efficiently, or produce more food with proportionately less water. Coping with water scarcity requires addressing a range of issues, not all of them directly linked to agricu- lture. They range from protection of the environment and global warming to fair pricing of water services and equitable distribution of water .for irrigation, industry and household use. This is why not only the agriculture sector, but everyone, international organizations, governments and local communities must share the responsibility.
