We report on the effect of expansion of invasive tree species(Prosopis juliflora) on household income in the semi-arid farm village in Tamil Nadu, India. Prosopis land cover had been expanded rapidly since 2000, and it shared 72% of the agricultural land. The invasion of Prosopis forced the farmers to give up their agricultural practice. However, the result of this study exhibited that the household income of the villagers was increased because the constant price of prosopis increased more than double. Such price changes were created by the increasing demand for prosopis, because several power stations using prosopis as an electricity generation material had been established nearby village.

我们报告了入侵树种（Prosopis juliflora）的扩张对印度泰米尔纳德邦半干旱农场家庭收入的影响。自2000年以来，牧草土地覆盖面积迅速扩大，占农业用地的72%。牧牛草的入侵迫使农民放弃他们的农业实践。然而，这项研究的结果表明，由于牧草不变价格增加了一倍以上，村民的家庭收入增加了。这种价格变化是由于对Prosopis的需求不断增加而造成的，因为附近村庄建立了几座使用Prosopis作为发电材料的发电站。
