iSQAPER's 14 study sites are located in a range of pedo-climatic zones and farming systems in Europe and China. Stakeholders in the study sites (farmers, technical advisors, researchers and policy makers) have been central to the research programme. In consultation with these stakeholders, a number of promising sustainable agricultural management practices have been identified and evaluated in field trials.  This and other sections of iSQAPERiS describe how these stakeholders have also been involved in the designing the functionality of SQAPP and in evaluating it during its development.
