In recent decades, changes that human activities have wrought in Earth’s life support system have worried many people. The human population has doubled in the past 40 years and is projected to increase by the same amount again in the next 40. The expansion of infrastructure and agriculture necessitated by this population growth has quickened the pace of land transformation and degradation. We estimate that humans have modified >50% of Earth’s land surface. The current rate of land…

How ecological feedbacks between human population and land cover influence sustainability

This model model of human population over the next century shows that an imprudent proactive approach limits the success of reactive measures in the future, while the inability to react to changes and recover natural systems leads to human population decline.

Responsible marine aquaculture can complement responsible land‐based agriculture and aquacultural and well‐managed fisheries to increase the global supply of nutritious food.

A Global View on Future Major Water Engineering Projects

Human activities have altered how the world functions. During the past decades, we have globally, fundamentally, in the long-term, and in most cases irreversibly modified all spheres of earth. This

The most important message in the history of mankind

The impact of human activities on the planet has accelerated the loss of species and ecosystems to a level comparable to a sixth mass extinction, the first driven by a living species, to suggest that the authors have triggered a new geological epoch, the Anthropocene.

Geo-ecology in the Anthropocene

Human activities have left signatures on the Earth for millennials, and these impacts are growing in the last decades. As a consequence, recent global change suggests that Earth may have entered a

The human-landscape system: challenges for geomorphologists

Deliberately or indirectly, most of the terrestrial surface has been affected by the actions of human beings. For that reason, geomorphologists have needed to broaden their scope of inquiry to

From a biophysical perspective, recovery of ∼5 percent of PDIV is feasible over the next 25 years and capitalizing on natural recovery mechanisms is urgently needed to prevent further irreversible degradation and to retain the multiple values of productive land.

Quantifying and mapping the human appropriation of net primary production in earth's terrestrial ecosystems

A comprehensive assessment of global HANPP based on vegetation modeling, agricultural and forestry statistics, and geographical information systems data on land use, land cover, and soil degradation that localizes human impact on ecosystems suggests large-scale schemes to substitute biomass for fossil fuels should be viewed cautiously.

Tracking the ecological overshoot of the human economy

It is indicated that human demand may well have exceeded the biosphere's regenerative capacity since the 1980s and humanity's load corresponded to 70% of the capacity of the global biosphere in 1961, and grew to 120% in 1999.
