The indigenous Nasa people live on a reservation that is in a biologically rich ecosystem, which they rely upon to practice subsistence farming, flower cultivation, and small-scale livestock rearing . Their territory encompasses forests, agroecosystems, natural parks, as well as Colombia’s most important water reservoir . The Nasa have also long struggled against illegal operations on their territory including mining, but especially concerning coca crops. Various armed groups such as FARC (Revolutionary Armed Forces of Colombia People's Army) dissidents, National Liberation Army guerrillas, the Clan del Golfo, and other groups are responsible for the illegal operations in the area and causing a war over resources and territory . The drug traffickers have overcome military and police forces, effectively seizing control of the region from the government. These syndicates are also suspected of having powerful political ties .
