The problem

No grass grows where the invasive weed prosopis has taken hold, so the animals are turning to the weed and its pods for sustenance. This is not providing them with the right nutrition so they are growing thinner and dying. The weed's thorns are also poisonous and are making those who come into contact with them permanently lame. 

Many of the villagers try to graze elsewhere but they are often turned away as people from neighbouring villages don’t want the weed spreading to their land.

Many people can't afford to keep livestock anymore and have nowhere to graze them because of prosopis. It’s causing huge problems for Grace and her fellow villagers. 


  • Loss of livestock
  • Maiming animals and people
  • Decreasing grazing land
