    The Global Land Outlook is【C5】________as the most comprehensive study of its type, mapping the interlinked impacts of urbanization, climate change, erosion and forest loss.

Heavy tilling, multiple harvests and【C7】________use of agrochemicals have increased yields at the【C8】________of long-term sustainability. In the past 20 years, agricultural production has increased threefold and the amount of irrigated land has doubled, notes a paper in the Outlook by the Joint Research Centre (JRC) of the European commission. Over time, however, this【C9】________fertility and can lead to abandonment of land and【C10】________desertification.

选项

答案 D

解析 空格前是形容词alarming,且分析句子结构可知,本句缺少主语,此外由修饰该主语的定语从句中的is可知,此处应该填入一个单数名词或不可数名词作主语。上文提到了土地的严重退化和肥沃土壤的严重流失,故此处说的应该是土地数量的减少令人担忧,故D)decline“降低,减少”为本题答案。
