A safe operating space for humanity
Identifying and quantifying planetary boundaries that must not be transgressed could help prevent human activities from causing unacceptable environmental change, argue Johan Rockstrom and colleagues.
Catastrophic shifts in ecosystems
Recent studies show that a loss of resilience usually paves the way for a switch to an alternative state, which suggests that strategies for sustainable management of such ecosystems should focus on maintaining resilience.
Global Consequences of Land Use
Global croplands, pastures, plantations, and urban areas have expanded in recent decades, accompanied by large increases in energy, water, and fertilizer consumption, along with considerable losses of biodiversity.
Solutions for a cultivated planet
It is shown that tremendous progress could be made by halting agricultural expansion, closing ‘yield gaps’ on underperforming lands, increasing cropping efficiency, shifting diets and reducing waste, which could double food production while greatly reducing the environmental impacts of agriculture.
Planetary boundaries: Exploring the safe operating space for humanity
Anthropogenic pressures on the Earth System have reached a scale where abrupt global environmental change can no longer be excluded. We propose a new approach to global sustainability in which we…
Estimating historical changes in global land cover: Croplands from 1700 to 1992
Human activities over the last three centuries have significantly transformed the Earth's environment, primarily through the conversion of natural ecosystems to agriculture. This study presents a…
Yield Trends Are Insufficient to Double Global Crop Production by 2050
Detailed maps are presented to identify where rates must be increased to boost crop production and meet rising demands, which are far below what is needed to meet projected demands in 2050.
Monitoring and estimating tropical forest carbon stocks: making REDD a reality
Reducing carbon emissions from deforestation and degradation in developing countries is of central importance in efforts to combat climate change. Key scientific challenges must be addressed to…
An integrated biosphere model of land surface processes
Here we present a new terrestrial biosphere model (the Integrated Biosphere Simulator - IBIS) which demonstrates how land surface biophysics, terrestrial carbon fluxes, and global vegetation dynamics…
Global response of terrestrial ecosystem structure and function to CO2 and climate change: results from six dynamic global vegetation models
The possible responses of ecosystem processes to rising atmospheric CO2 concentration and climate change are illustrated using six dynamic global vegetation models that explicitly represent the…
