Decision making and food safety: the case of barley producers in Uruguay

Barley is an important crop in Uruguay, sown mainly through contracts with malting companies, with quality requirements for malting that do not contemplate the maximum residue limits (mrls) of fungicides established by official bodies. Farmers present heterogeneity in organizational and productive aspects, generating different incentives for decision-making. The objective of this...

Manufacturing agroecology: lessons from social development projects

Agroecology appears as the main alternative to think of new more diversified and sustainable production systems that respect natural resources. Starting from experiences of community processes of social development in rural areas, privileging collective reflection on ways of doing things and identifying those shortcomings, we reflect here on co-innovation as a methodology for...
