Collapse and the interplay between essentiality and impact in socioecological systems

Area of Science:

• Complex systems science
• Ecological economics
• Social-ecological dynamics

Background:

• Previous models often conflated environmental and social factors in system collapse.
• Understanding the essentiality of goods and services is crucial for system stability.
• Nonequilibrium dynamics play a significant role in social-ecological interactions.

Purpose of the Study:

• To introduce a novel nonequilibrium toy model for social-ecological system interactions.
• To differentiate between environmental collapse and collapse due to consumption imbalances.
• To identify sustainable and unsustainable phases and predict collapse likelihood.

Main Methods:

• Analysis of different phenomenological parameter regimes.
• Development and application of novel analytical and computational techniques.
• Investigation of the stochastic version of the model.

Main Results:

• Identification of distinct sustainable and unsustainable phases within the model.
• Quantification of the likelihood of system collapse under various conditions.
• Validation of model behavior against real-world collapse processes.

Conclusions:

• The model successfully distinguishes between types of collapse, offering new insights.
• The identified phases and collapse likelihoods provide a framework for understanding system dynamics.
• The stochastic model's consistency with real-world phenomena highlights its applicability.
