摘要：The Global South is facing severe challenges in ensuring livelihood security due to climate change impacts, environmental degradation and population growth as well as changing lifestyles.These complex problems cannot be solely solved by single scientific disciplines – they require transdisciplinary research (TDR).Stakeholders from civil society, the corporate sector, government and science need to pool their knowledge to find solutions for sustainable transformations.In Namibia, we have been involved in TDR projects on water supply, and sanitation services as well as livestock management in rangeland systems.In this paper, we review two TDR projects that differ in multiple ways and hence allow us to carve out structural differences and critically discuss research outcomes, lessons learned and the challenge of North–South collaborations.Our review builds upon published and unpublished project documents as well as expert interviews with Namibian and German researchers who were involved in the projects.Our results show that TDR can be put into practice in different ways, depending on the research focus and the period available.The TDR phases of problem framing, inter- and transdisciplinary integration were implemented with different tools and foci points.We discuss the role of project length and funding conditions for project success and outcome generation.In addition, we critically consider the role of Namibian and German researchers in these international collaborations.The conclusions we draw touch upon the points of preparatory research funding, the equal acknowledgement of Global South contributions to joint research projects and the explicit handling of TDR components in project work.
