Welcome to my Website. We live in times of escalating ecological crises that really threaten our lives, livelihoods and future. The need to transform our societies towards sustainable development is becoming more and more urgent. Global heating, biodiversity loss, energy transition, resource conservation and environmental justice, all these issues are pressing and start to shape the political agenda on local, regional, national and international levels. Therefore technological change is as important as lifestyle change and cultural change and a new economic order, that serves people and does not oppress, functionalize and alienate them from environmental and social needs. On this website, I want to share my ideas and experiences in the field of sustainable development in the scientific, political and NGO arena and as a writer with you. Comments are welcome.
