The partners of Mesopartner met the first week in January in Pretoria, South Africa, for our annual meeting to plan the year. Among other things, we discussed our two annual training events in 2020 (an introduction to MSD & LED in Hanoi, Vietnam; and the Summer Academy in Berlin, Germany). We also reflected on our research themes on Analysing and Enhancing the Meso Level and on Quality Infrastructure for Development and how to advance them further in 2020. Furthermore, we discussed our role in the Great Sustainability Transformation through our work in development and also how our own behaviour impacts climate. As we all live in different parts of the world, we appreciate these opportunities to reflect and learn together.
