Other indigenous Janajati ethnic groups -— natively speaking highly localized Tibeto-Burman languages and dialects -— populate hillsides up to about . This group includes Magar and Kham Magar west of Pokhara, Gurung south of the Annapurnas, Tamang around the periphery of Kathmandu Valley and Rai, Koinch Sunuwar and Limbu further east. Temperate and subtropical fruits are grown as cash crops. Marijuana was grown and processed into "Charas" (hashish) until international pressure persuaded the government to outlaw it in 1976. There is increasing reliance on animal husbandry with elevation, using land above for summer grazing and moving herds to lower elevations in winter. Grain production has not kept pace with population growth at elevations above where colder temperatures inhibit double cropping. Food deficits drive emigration out of the Pahad in search of employment.
