Sustainable impact investigates the role of business in society and its potential to contribute to the UN Sustainable Development Goals (SDGs). The idea of sustainable impact is to improve institutional conditions that encourage public and private interest groups to engage in cooperation on the local, national, and international levels and enable together inclusive and sustainable change. In our concrete projects in Africa and Eastern Europe, we study the successes and failures of development cooperation in rural development and the build-up of sustainable economic ecosystems. In our projects, we are dedicated to the interdisciplinary merging of anthropology, economic sociology, and political economy, and in our approach, we apply qualitative and quantitative methods. The combination of interdisciplinarity and fieldwork research enables us to provide thorough, profound, and applicable analyses and solutions to sustainable change.
