Economic analysis of integrated vegetable-poultry production systems in the Babati District of Tanzania por Habiyaremye, Naphtal, Ochieng, J., Heckelei, T.

“…The same applies regarding the knowledge on factors influencing the decision to adopt such an integrated system.Using cross-sectional data collected from 250 households in Babati district of Tanzania, we employ a gross margin analysis and a logit model to evaluate the profitability and to investigate the factors influencing the decision to integrate vegetable and poultry production systems.We find that the integrated vegetable–poultry production system is more profitable than vegetable farming alone and the profitability increases as the poultry flock size increases. …”

Sustainable but hungry? Food security outcomes of certification for cocoa and oil palm smallholders in Ghana por Dompreh, E.B., Asare, R., Gasparatos, A.

“…These results suggest that even though certification adoption can improve the livelihoods and yields of farmers, in reality it has marginal effect on food security. Certification standards would need to emphasize food security in their guidelines, theories of change and support packages to smallholders if they are to enhance food security and have a truly positive effect on the sustainability of cocoa and oil palm production.…”
