Biodiversität

• Langzeitbeobachtung von Pflanzengemeinschaften im ariden Südafrika
• Standortheterogenität als Steuerungsfaktor für Diversität
• Einfluss von Landnutzung und Klimawandel auf Vegetation und Diversität
• Partizipative Biodiversitätsforschung durch Paraökologen (s. http://www.paraecologist.org)

Ökologie

• Vegetationsökologie der Trockengebiete des südwestlichen Afrika
• Vegetationsmuster und ihre Steuerungsfaktoren (DFG-Projekt)
  
• Überlebensstrategien trockenangepasster Pflanzen (funktionelle Merkmale, Strategietypen)
• Vegetationsdynamik in der Sukkulenten Karoo
• Restoration degradierter Biodiversität
• Anpassungsstrategien von Kleinbauern an Klimawandelbedingungen

Mit transdisziplinären und Partizipative Action Research-Ansätzen werden gemeinsam mit Landnutzern existierende Anpassungsstrategien an Dürre und Klimawandelbedingungen identifiziert, bewertet und, wo angemessen, weiter entwickelt.
