Katrien Descheemaeker is assistant professor in the Plant Production Systems group of the Plant Science Department of Wageningen University (Netherlands). She obtained a PhD in Bioscience Engineering from the KU Leuven (Belgium) on land degradation and rehabilitation in the Ethiopian highlands. As a joint postdoc with the International Livestock Research Institute and the International Water Management Institute in Addis Ababa (Ethiopia), she studied water productivity in smallholder mixed crop-livestock systems. During the 1.5 years as a research scientist at CSIRO in Australia, Dr. Descheemaeker conducted agricultural research in African smallholder systems and in the Australian mixed sheep-cereal farming systems. Katrien's current research focuses on farming systems analysis, soil-plant-animal interactions, sustainable development and resource use efficiency, with a special interest in the functioning and dynamics of mixed crop-livestock systems. Current activities combine experimental trial work with simulation modelling to identify and assess options for sustainable intensification and adaptation to climate change. Across various projects on smallholder farming systems in sub-Saharan Africa, Dr. Descheemaeker develops methods for participatory research with farmers and other stakeholders to increase the potential adoption and impact of technology and management options to increase farm productivity, food security and natural resource integrity.
