Palpa District Present SituaUon Palpa District is located in the Lumbini Zone and consists administratively of 9 Ilakas and 65 Village Development Committees and 1 Nagarpalika. The total area of the District is 1449 krn2. The environment of the district is mountainous, altitude varying form 251 m to 1943 m. 52 % of the district is classified as forest and 22 % as cultivated land. Intensive use of land cause land erosion and landslide problems. High population density and shortage of cultivable land creates a pressure to take steep slopes under cultivation. The total population of the district was 288,829 and rural population was 272724 in 1993 consisting of 40,907 (rural) households.average populationThe averagedensityhouseho]d199 people/km2.RiZC is thusMajor6.67ethnicpersons/hhgroups areand brahmin-chettris, gurungs, magars, sarki, kami and newars. The economy of the district is entirely based on agriculture - mostly subsistence farming. The health statistics of the dLstrict show, that major groups of the disease are water and .~~nitation related, skin diseases, dysentery, diarrhoea and worms being most common reasons for seeking the medical help.

With regard t~ water supply and sanitation, the target is to serve 72 % of population by improved water supplies and 9 % by improved sanitat n faculties by the year 1997.
