LAM PA CHI RIVER BASIN (THAILAND)
The total population of the basin adding the number of inhabitants of the four main sub-districts (Dan Makham Tia, Chom Bung, K. Ban Kha, Suan Phung) is 143,375 and according to Biltonen et al. (2003) over 80% of the population can be considered as rural. The rural population is mainly dependent on agricultural production and its related activities.
The main crops cultivated in the region include pineapple, sugar cane, cassava and others. The production is mainly exported to other regions within the country and only two small factories transform the raw material into a food industry product: canned pineapple.
Non-agricultural production land uses accounts only 2.5% total area and mainly are lands for mining, rural settlement, transportation. Land use for urban activities is insignificant as the fact of low urbanization in the region.
Lands for agricultural production distribute in the eastern lower parts and along the large streams. 38% area of basin serves for agricultural production. Sugarcane is planted in the largest areas, approx. 50,000 ha (20% total area). The other major cultivated plants are cassava, pineapple and paddies. Paddy rice is plated in 4,760 ha and mainly is irrigated. In smaller proportion other crops such as corn, tamarind and mango are also cultivated.
