Valuing Ecosystem Services in the Lower Mekong Basin: Country Report for Cambodia
The study in Cambodia adopted three valuation techniques: market prices, market substitutes, and avoided costs.
Most household income among local communities is generated from farming, fishing and forest products, and almost all of these resources come from Ream National Park. Up to 84 percent of households gather firewood from it, a quarter are involved in timber harvesting and 18 percent collect wild plants for food, medicines, and handicrafts. Nearly 30 percent of marine fishes, crustaceans and shells, and 8 species of freshwater fish, are also harvested within the park’s boundaries.
Surveys determined a net value of some $1.2 million a year for these products, translating to $220 for each household in or beside the park, a significant amount given a median income of $316 a year. Its mangrove forests also act as a buffer from storm surges, protecting homes and valuable infrastructure.
The report includes a seven-step process for determining such valuations and shows how they can be applied to policy venues.
