Over the years, the Committee on Sustainable Assessment (COSA) has conducted dozens of experimental and quasi-experiment impact assessments in countries around the world. COSA employs the most rigorous methodologies available to better understand the social, economic and environmental impacts of agriculture in the belief that credible evidence of what works and what does not will lead to more sustainable practices. One of the ways that COSA pursues its goals is by conducting statistically significant surveys informed by detailed qualitative research that starts with development of a theory of change and is validated through wide-ranging stakeholder interviews.
