THE MUANG FAAI IRRIGATION SYSTEM OF NORTHERN THAILAND
SECTION 1
Northern Thailand consists mainly of long mountain chains
interspersed with valley
bottoms where streams and rice fields dominate the landscape. Most of the remaining
forests of the North are found at higher altitudes. The forests ensure regular seasonal
rainfall for the whole area and at the same time moderate runoff, so that there is
water throughout the year.
SECTION 2
The lowland communities have developed an agricultural
system adapted to, and
partially determining, the distinctive ecosystems of their areas. Practicing wet-rice
agriculture in the valley-bottoms, the lowlanders also raise pigs, ducks and chickens
and cultivate vegetable gardens in their villages further up the slopes. Rice, beans, corn
and native vegetables are planted in
hill fields above the villages, and wild vegetables
and herbal medicines are gathered and wild game hunted in the forests higher up the
hillsides. The forests also serve as grazing grounds for cows and buffalo, and are a
source
of wood for household utensils, cooking fuel, construction and farming tools.
Fish are to be found in the streams and in the irrigation system and wet-rice fields,
providing both food and pest control.
