The working group Sustainable Land Use in Developing Countries (SusLAND) focusses on the analysis of land use and landscape systems in emerging and developing countries. Based on the analyses, interdisciplinary research methods are used to develop strategies to mitigate complex problems of farming systems in developing countries at local, regional and global scales. Emphasis is placed on questions regarding the avoidance of land use conflicts, the improved adaptation to climate change, food and nutrition security, and the stabilization of the livelihood of family farms. SusLAND operates in Sub-Saharan Africa, Latin America and South Asia and focusses in particular on resource economics in combination with natural sciences.

Ilona M. Otto specializes in institutional and political economy, having graduated with a masters in sociology and obtained a PhD in resource economics. In her most recent research, she analyzes social tipping dynamics for the stabilization of the Earth’s climate as well as the implications and implementation of human agency for modeling human-environmental system interactions. She is also interested in environmental inequalities and the socio-metabolic implications of resource and energy, used to support lifestyles of different social groups. She contributes to two teaching modules taught within the International Master of Natural Resource Management degree program coordinated by the Resource Economics Group at the Humboldt University. The teaching modules include Climate and Energy Management and Advanced Empirical Methodology for Social-Ecological System Analysis. She is also an Associated Fellow at the Berlin Workshop in Institutional Analysis of Social-Ecological Systems (WINS) hosted by IRI-THESys Institute at the Humboldt University.
