In June 2015 in Uganda, use of the aquatic weed harvester was recommended by the country's Ministry of Agriculture to reduce water hyacinth growth in Lake Victoria, which has caused a scarcity of fish in the lake.[11] The scarcity of fish has negatively-affected the livelihood of locals who live in the lake's region.[11] Additional types of machines were recommended to address the problem, which were the hydraulic harvester, take out elevator and dredger.[11]
