Descripción
Health and environmental concerns associated with pesticide use have motivated the development of integrated pest management
(IPM) programs around the world. Little empirical work has been completed to estimate the value of the environmental
benefits of IPM. This paper provides an approach to evaluate a broad set of such benefits for a vegetable program in the
Philippines. Assessments were made of (1) IPM-induced reduction in environmental risks posed by pesticides in onion production
in the Central Luzon and (2) willingness to pay to reduce those risks. The latter was based on a contingent valuation
(CV) interview survey of 176 farmers. Risks to humans, birds, aquatic species, beneficial insects, and other animals were
considered. IPM practices on onions reduced the use of specific pesticides from 25 to 65%, depending on the practice, and the
projected adoption ofiPM practices varied from 36 to 94%. Estimated economic benefits varied from 231 to 305 pesos per
person per cropping season (40 pesos = 1 US$). The aggregate value of environmental benefits for the five villages where the
IPM research program was centred was estimated at 150,000 US$ for the 4600 local residents. Assessment of environmental
benefits can help in designing public policies and regulations, and in justifying support for publicly funded IPM programs.
