Effect of expansion of invasive tree species on farm household income in Tamil Nadu, India

我们报道了在印度泰米尔纳德邦一个半干旱的农业村庄，入侵树种(Prosopis Juliflora)的扩张对家庭收入的影响。自2000年以来，Prosopis的土地覆盖迅速扩大，占农业用地的72%。Prosopis人的入侵迫使农民放弃了他们的农业实践。然而，研究结果表明，由于不变价格增加了一倍多，村民的家庭收入增加了。这种价格变化是由于对蜂胶日益增长的需求造成的，因为在村庄附近建立了几个使用蜂胶作为发电材料的发电站。

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.
