M. Umezaki et al., Diet among the Huli Papua New Guinea Highlands when they were influenced by the extended rainy period, ECOL FOOD N, 37(5), 1999, pp. 409-427
Household food consumption surveys (weighed records for 7 days) were conduc
ted in two Hull-speaking communities, Hell in the slope zone and Wenani in
the nat plain, in Papua New Guinea Highlands when their food productivity h
ad decreased after an extended rainy period in 1994. Despite lowered produc
tivity of garden crops in both communities, daily adult male energy and pro
tein intakes in Wenani (12930 kJ, 3090 kcal and 56 g, respectively) exceede
d the requirement and safe levels by FAO/WHO/UNU (1985), whereas those in H
ell (7750 kJ, 1852 kcal and 35 g) were below both levels. The difference wa
s mostly attributable to three times higher productivity of food energy in
the normal period in Wenani than in Hell. The findings are relevant to the
maintenance of food security among Papua New Guinea Highlanders.
