Formed in 1973, the Peasant Movement of Papaye (MPP) is the oldest peasant association in the country, with a broad range of self-help development activities aimed at improving peasants' quality of life. The MPP's program areas include training in leadership and organization; agricultural production and animal husbandry; cooperatives (ceramics, sewing, as well as agricultural production and marketing); health care for peasants; and alternative tourism and investment schemes.

Grassroots is currently supporting the MPP's reforestation and sustainable agriculture work in the environmentally devastated Central Plateau.
