Biodiversity

• Long-term observation of plant communities in arid South Africa
• Habitat heterogeneity as a driver of diversity
• Influence of land use and climate change on vegetation and diversity
• Participatory biodiversity research by paraecologists (see http://www.paraecologist.org)

Ecology

• Vegetation ecology of the arid areas of southwestern Africa
• Vegetation patterns and their environmental drivers (DFG project)
• Survival strategies of aridity-adapted plants (functional characteristics, strategy types)
• Vegetation dynamics in the Succulent Karoo
• Restoration of degraded biodiversity
• Adaptation strategies of small-scale farmers to climate change conditions

Using transdisciplinary and participatory action research approaches, existing adaptation strategies to drought and climate change conditions are identified, evaluated and, where appropriate, further developed together with land users.
