The first Earth Summit took place in 1992 in Rio de Janeiro, - this was the UN Conference on Environment and Development (UNCED), from which the three major environmental agreements on climate, biodiversity and desertification (UNFCCC, CBD, UNCCD) emerged. The Precautionary Principle was established as a fundamental part of the CBD. Just a few months later, in December 1992, the UN Commission on Sustainable Development (CSD) was created “to ensure effective follow-up of Rio Earth Summit”. There were high hopes that at last the international community would begin to address some of the major collective issues of planetary health: biodiversity loss, climate change and desertification.
