Formatted abstract

Chemicals mismanagement has potential high risks for the farmers and community’s health as well as for the environment; therefore it is important to identify factors that influence farmers’ behaviours in relation to chemical use. Several studies have been conducted evaluating farmers’ practices and attitudes when applying pesticides, and there is vast evidence in regards to the negative health consequences due to chemical exposure. Furthermore, the literature offers evidence of the positive effects of education, training and information in the adoption of safer practices. Most of the studies conducted in the context of the developing world took place in Africa, Asia and Latin America and the main methodologies applied have been binary responses models such as probit and logit. This empirical study assesses small holders’ attitudes towards chemicals for weed control in Papua New Guinea main four coffee producing provinces. The aim is to evaluate the significance of demographic factors and other factors such as training and information in the attitudes towards use of safety equipment and disposal of chemical containers. Because of the likely endogeneity of training, the special regressor method developed by A. Lewbel and co-authors is applied to provide robust results in the case of binary choice models with discrete endogenous regressors. The results show that training in pest management increases the likelihood of households adopting safer practices. For the case of safety equipment, not only training in pest management was significant but also access to information on pest management, age of the household's head, whether there is some organically-certified coffee produced in the district, and province of residence. In the model for disposal of chemical containers, training in pest management, age and education of the household's head, and an index of remoteness were significant in explaining the farmers’ attitudes.
