Localized ecological systems are known to shift abruptly and irreversibly from one state to
another when they are forced across critical thresholds. Here we review evidence that the …

Most commentators expect improved energy efficiency and reduced energy demand to
provide the dominant contribution to tackling global climate change. But at the global level …

Although complexity surrounds us, its inherent uncertainty, ambiguity, and contradiction can
at first make complex systems appear inscrutable. Ecosystems, for instance, are nonlinear …

Climate change challenges societal functioning, likely requiring considerable adaptation to
cope with future altered weather patterns. Machine learning (ML) algorithms have advanced …

Humans, unlike any other multicellular species in Earth's history, have emerged as a global
force that is transforming the ecology of an entire planet. It is no longer possible to …

Environmental problems have contributed to numerous collapses of civilizations in the past.
Now, for the first time, a global collapse appears likely. Overpopulation, overconsumption by …

Bioelectrochemical systems (BESs) are unique systems capable of converting the chemical
energy of organic waste including low-strength wastewaters and lignocellulosic biomass …

The progressive reduction of high-quality-easy-to-extract energy is a widely recognized and
already ongoing process. Although depletion studies for individual fuels are relatively …

Energy systems research requires a variety of demand scenarios for possible futures.
Comprehensive energy demand modelling is often made with a simplified approach or …

This book grew out of our intensive research collaboration over the last 9 years. The order of
the book's authorship could have been determined by a coin flip. Shared interests in the …
