As development and security concerns increasingly converge, there is a need for better impact assessments of development aid on peacebuilding. The logistical challenges in conflict zones have often made the conduction of evaluations impossible due to budget and time constraints. This paper presents a method which could help to overcome these challenges by combining quantitative assessment (survey methods) at separate intervals with qualitative field research methods. The former are used to identify general trends in the local population while the latter make it possible to trace processes and to check for local idiosyncrasies. The method is illustrated with examples from ongoing work in North East Afghanistan.
