I am a Geo-Ecologist with a long-term research experience in vulnerability of socio-ecological systems, the development of adaptation strategies and institutional analyses. My research has centred on the investigation of smallholder livelihoods in drylands with regard to food security and global change. In particular, I have revealed major mechanisms which generate vulnerability to climate variability, price fluctuations and other perturbations. Thereby, the transfer of options to adapt to perturbations and inter-linkages between local and global scales receive particular attention. Moreover, my work includes development of approaches to integrate case study knowledge with modelling techniques. I have extensive regional and fieldwork experience in Latin America and Africa, in particular in the Peruvian Andes, Northeast Brazil, Mozambique and western Africa.
I have contributed to high-level flagship reports of international and national organisations including UNEP and the German Advisory Council on Global Change, to priority setting in the European research agenda of JPI CLIMATE and delivered lectures to the Subsidiary Body for Scientific and Technological Advice/Subsidiary Body for Implementation of the UNFCCC as well as at the Annual Reporting and Exchange Platform for Climate Change Management (Peru).
