Welcome to the cooperation platform for the BMBF (German Federal Ministry of Education and Research) research programme Tipping Points, Dynamics and Interdependencies of Social-ecological Systems – BioTip, which started with a preparation phase in 2017-2018, followed by a main phase 2019-2022.

Why have/fund a research programme on tipping points?

Tipping points, caused by human action, are a major concern for decicion-makers, because of their potentially large impacts on biodiversity, ecosystem services, climate change and human well-being. A well-known example of an ecosystem tipping point is the sudden shift of ponds or shallow lakes from a clear to a turbid, algal bloom, state. “Tipping points – where a small perturbation triggers a large response – produce abrupt system-wide and sometimes irreversible change” (Lenton 2013).

“Politicians, economists and even some natural scientists have tended to assume that tipping points in the Earth system — such as the loss of the Amazon rainforest or of the West Antarctic ice sheet — are of low probability and little understood. Yet evidence is mounting that these events could be more likely than was thought, have high impacts and are interconnected across different biophysical systems, potentially committing the world to long-term irreversible changes” (Lenton et al. 2019, citations under ‘Links’).  The international research programme BioTip aims at a better understanding of such tipping point phenomena in social-ecological systems. It is also dedicated to the development of a course of action to support ecosystem stability and thus secure biodiversity.
