The tropics are home to the largest share of the world's biodiversity. At the same time, they are regions where persistent poverty, population increase and climate change pose major threats to the food security of the local populations. Therefore, there are in great need of sustainable modes of land-use, which maintain diversity at all levels. This is achieved at best through multi-crop prodction systems, hence forests and agroforestry could not be missing from the international discourse for development on the margin. This year's Tropentag covered the topic through numerous posters and oral presentations, with interesting contributions from both theory and practice. Julia Szulecka from the Technische Universität Dresden, traced the development of historically changing assumptions, concepts, values and practices that constitute our way of viewing plantation forestry. By doing so, she drew a direct correlation between the evolution of meanings and associations related to forest plantations and the development of plantation-related policies.
