Demography
The droughty and agriculturally unproductive Dudhwa range creates a buffer zone between the divergent cultures of the plains of Uttar Pradesh and the Inner Terai. Deukhuri was severely malarial before the late 1950s when DDT came into use to suppress mosquitos so that Tharu people who had evolved resistance managed to live in isolation from more developed and avaricious cultures of the plains to the south and the hills to the north. Although road development further reduced Deukhuri's isolation by the 1980s, the valley retains some of its Garden of Eden charm with its lazy river, thick jungle alternating with rice paddies, surrounding hills in the middle distance, and unique peoples.
Dang Valley is higher, less tropical, drier and less malarial than Deukhuri. Despite poorer soil and more seasonal streamflow, its healthier climate made it more attractive to settlers from outside even before the introduction of DDT.
Since the early 1990s activist groups have been attempting to eradicate the practice of child indentured servitude among the Tharu, many of whom sold young daughters to wealthy families in urban areas.
The steep, virtually uninhabited southern slopes of the Mahabharat Range are another cultural buffer zone between traditional Tharu lands and the culturally distinct Middle Hills where Nepali is the dominant language, the homeland of Nepal's politically dominant Bahuns and Chhetris. There are many type of caste live togather in a small area.
This area found several years ago our ancestor. that time this area is undeveloped. But nowadays persons are literated.
