Evidence as to whether sustainability standards are effective in changing farm management is still scarce. This webinar will present the learnings of the study ‘Agricultural certification improves uptake of sustainable farming practices over time’ which assesses compliance with the Rainforest Alliance Sustainable Agriculture Standard (RA/SAN) of 576 certified organizations, representing more than 800,000 individual farmers and more than 1.5 million hectares. These certified farm organizations are present in major growing regions of coffee, cocoa, tea, and banana, i.e. four of the most significant tropical export crops. The paper examines farm compliance scores at the certified organizations for key sustainability categories, at the most recent audit, over time, and in response to various predictor variables.
