註釋The Dominican Republic is facing a major natural resources problem, because many small hillside farmers have destroyed the natural perennial groundcover and replaced it with short cycle crops on slopes which often surpass 100%. Around 22% of the nation's land area is devoted to land uses ecologically inappropriate to hillside farms. These lands are seriously threatened by high soil erosion rates, caused by current cropping patterns.
