In this successful payment for watershed services (PES/PWS) pilot program, CARE-Kenya, World Wildlife Fund, and the Kenyan Ministry of Agriculture helped major commercial horticulture growers (flowers) on the banks of Lake Naivasha in Kenya's Rift Valley test a program to pay and train smallholders in the upper watershed to improve their farming practices in order to reduce soil erosion and improve water quality flowing into the lake, which the large-scale growers use for irrigation. As a result smallholders increased their incomes from improved crops and fodder for their livestock, while enhancing their families' nutrition and their environmental sustainability.
