Currently, research on the outcomes and impacts of Rainforest Alliance training and certification on tea farms is sparse. To begin to fill this gap in an accountable and transparent yet cost-effective way, the Rainforest Alliance looked at data found in certification audit reports from Malawi, Rwanda and Tanzania. They include data on a farm’s compliance with specific criteria in the SAN Sustainable Agriculture standard at the time of the first audit and at all subsequent audits, allowing us to determine how compliance rates for individual criteria change over time. This information is also important to providers of pre-certification technical assistance, who can use the results to tailor their support to the specific needs of farms in study countries. The audit reports also reveal the areas of relatively low compliance, offering important information to technical assistance providers, who can then tailor their support to the specific needs of farms in study countries.
