The problem

The land around Robie’s village is being taken over by Chromolaena. The weed displaces native flora, which means her livestock aren;t getting the nutrition they need to stay healthy and getting thinner and thinner.

Chromolaena has also reduced soil fertility so it is harder to grow crops. Yields have declined. 

The weed is very aggressive, so it is very hard for the villagers to control.


  • Loss of livestock
  • Decreased grazing land
  • Reduced soil fertility
  • Poor crop production
