Agricultural sustainability and intensive production practices
A doubling in global food demand projected for the next 50 years poses huge challenges for the sustainability both of food production and of terrestrial and aquatic ecosystems and the services they…
Effect of aquaculture on world fish supplies
If the growing aquaculture industry is to sustain its contribution to world fish supplies, it must reduce wild fish inputs in feed and adopt more ecologically sound management practices.

Results indicate South Asia and Southern Africa as two regions that, without sufficient adaptation measures, will likely suffer negative impacts on several crops that are important to large food-insecure human populations.
Consequences of changing biodiversity
The large ecological and societal consequences of changing biodiversity should be minimized to preserve options for future solutions to global environmental problems.

Trends in fishmeal and fish oil use in industrial aquafeeds are reviewed, showing reduced inclusion rates but greater total use associated with increased aquaculture production and demand for fish high in long-chain omega-3 oils.
Historical Warnings of Future Food Insecurity with Unprecedented Seasonal Heat
Observational data and output from 23 global climate models show a high probability that growing season temperatures in the tropics and subtropics by the end of the 21st century will exceed the most extreme seasonal temperatures recorded from 1900 to 2006.
Framing Sustainability in a Telecoupled World
Interactions between distant places are increasingly widespread and influential, often leading to unexpected outcomes with profound implications for sustainability. Numerous sustainability studies…
Nutrient Imbalances in Agricultural Development
Solutions to the nutrient challenges that face global agriculture can be informed by analyses of trajectories of change within, as well as across, agricultural systems.
