This paper examines the economics of introducing conservation tillage into existing maize cropping systems in the state of Jalisco, in the western part of Mexico. A stochastic cost-benefit analysis (SCBA) of introducing ...

Results from a study of maize varieties and seed sources in a traditional community in Mexico raise questions about the relevance of models for in situ conservation of crop genetic resources that are based on geographical ...

In efforts to understand the process of agricultural develoµtent, economists and other social scientists have invested substantial resources in literally hundreds of studies of the adoption of new agricultural technologies. ...

The principal advantage of in situ conservation is that it allows adaptive evolutionary processes to continue in the species that are being conserved. For a cultivated crop species, in situ conservation involves farmers' ...

This study explores factors associated with farmers' decision to experiment with velvetbean (Mucuna spp.), a green manure, as a maize intercrop in three villages of Veracruz, Mexico. To asses whether velvetbean might be ...
