This paper identifies and addresses three key challenges in energy systems analysis—varying assumptions, computational limitations, and coverage of a few indicators only. First, results depend strongly on assumptions, i.e., varying input data. Henc

Little is known about the dynamics of human cooperation in groups with changing compositions. Using data from a large-scale and long-term online public goods game, this study shows how group changes are associated with temporarily lower cooperation.

A generalized knowledge of social-ecological relationships is needed to address current environmental challenges. Broadly comparative and synthetic research is a key method for establishing this type of knowledge. To date, however, most work on socia

Machine learning models have proven to be very successful in many fields of research. Yet, in natural resource management, modeling with algorithms such as gradient boosting or artificial neural networks is virtually nonexistent. The current state of

This article analyses actors in the storage niche during the German electricity transition. Thus, we develop a more differentiated understanding of actors and their storage activities. For that, we employ the analytical multi-level-perspective (MLP)

We report a potential self-reinforcing design flaw in the variable market premium scheme that occurs if variable renewable energy power plants receiving a premium become price-setting in the market. A high share of renewable energy is a goal of many

The literature on common pool resource (CPR) governance lists numerous factors that influence whether a given CPR system achieves ecological long-term sustainability. Up to now there is no comprehensive model to integrate these factors or to explain

This article argues that research on social-ecological systems could profit from the use of ontologies. Ontologies, i.e. formalized conceptualisations of a domain in a computer-readable format, allow making progress in different areas. In particular,

Misinterpretations of the p value and the introduction of bias through arbitrary analytical choices have been discussed in the literature for decades. Nonetheless, they seem to have persisted in empirical research, and criticisms of p value misuses h

Investment decisions in renewable energies are known to be influenced by many diverse drivers, e.g. social, political, geographic, economic and psychological. Non-comprehensive models are problematic since missed interactions might introduce bias. We
