1·And some of this extra land is offset by soil erosion.

部分额外土地被土壤侵蚀消耗着。

2·But that effect was offset by warming-associated drought that limited growth in the Southern Hemisphere, resulting in a net global loss of land productivity.

但是，这种积极影响被气候变暖带来的干旱所抵消，限制了南半球的植物生长，导致全球土地生产力出现负增长。

3·Even if organic farming does consume a little less energy and produce a little less pollution, that must be offset against lower yields and greater land use.

即便有机种植的确消耗更少能源，产生更少污染，但也会被低产以及使用更多耕地所抵消。

4·The cost of land leveling is offset by the low labor requirement for turning water into a few border rather than into many furrows or corrugations.

把水放入几块畦田比放人许多灌水沟或垄沟花费的劳力要少，这就补偿了平整土地的费用。

5·However, the collective-owned land shall not be used to offset the liabilities directly.

但集体所有的土地不能直接用以抵偿债务。
