“We still understand remarkably little of the mechanisms that determine major transitions in societies, or that regulate the stability and resilience of the climate and ecosystems.

It is usually asumed that the response to an alteration of our planet will be gradual, predictable, and reversible. However, abrupt changes are occasionally observed in nature and society.

Complex systems, ranging from the climate to ecosystems and society, can slowly lose resilience until even a minor perturbation can push them over a tipping point.

Rapid transformations and massive shifts can often be explained as so-called critical transitions.”

Ecological theory considers critical transitions as “sharp changes from one state to a contrasting one, where a state is a dynamic system with its characteristic fluctuations and cycles” (see The Synergy Program for Analysing Resilience and Critical transitionS (SparcS).

Drastic transitions following a tipping point, when a critical threshold is crossed, are studied as universal patterns in complex systems, such as ecosystems, societies, the climate and the human brain.

In shallow lakes, transparent states can lead abruptly to green and turbid ones, responding to changing conditions in nutrient loading or trophic changes.

The installation is a biofantasy landscape, using real freshwater ecosystems as metaphors of the ever-changing nature of all things. We can see 3 mesocosms with contrasting stages of real ecosystems, turbid and transparent. Organisms freely create their self-stabilizing systems.

In an experimental project, the unexpected is welcome. The water and the moon are used as universal symbols of change. 

Does this resonate with us? How should we approach change, in the Anthropocene? How should we follow the watercourse way?

new project: mayflies

In Spring, we see many mayflies in our home, which is an old mill beside a brook. Mayflies (Ephemeroptera) live in rivers and lakes, as immature nymphs. The winged adults breed and die soon thereafter. Their brief life tells us about cyclic change, and impermanence. And they are beautiful intricate fairylike minuscule creatures.
