| The adoption of organic production has increased dramatically over recent years, especially in less developed countries. However, little information is available about who adopts, the difficulties they face in converting and how these factors vary over time. Using small-scale avocado producers (<15ha) from Michoacán, Mexico as a case study, this paper explores the factors affecting the time-to-adoption of organic production and certification, drawing from five parametric descriptions of the data. These models are implemented using a Bayesian approach and advances in Markov chain Monte Carlo methods. The results indicate that additional sources of income, together with membership of producers associations, higher levels of education and experience of... |

| Traditionally the evaluation of animal genetic traits has focused primarily on production traits and the construction of selection indices. Selection indices, however, fail to consider the effect of management practices and the environment on productivity. Non-production traits are either under-valued or not valued at all. Given the changing demands placed on agriculture and the increased understanding of the effects of agriculture on the environment, this approach can be considered myopic. While techniques are available to link economic and biophysical/environmental models, little has been applied in the context of genetic trait evaluation. This paper therefore explores the potential for integration and the development of methods that capture not only... |

| Certified organic production by small-scale farmers in developing countries is increasingly promoted as an opportunity to access a growing and dynamic market, while at the same time, enhance productivity and improve incomes. Nevertheless, adoption has been limited. The economics literature suggests profitability is the main constraint, however, the sustainable agriculture literature is inconclusive and considers attitudes of significant importance. Using the Theory of Planned Behaviour, this study investigates the psychological barriers to adoption using small-scale avocado producers from Michoacan, Mexico as a case study. The data is obtained from a household study carried out during 2004 and is modelled using an ordered probit model. Despite positive... |
