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 theyExpand
Agroecosystems, Nitrogen-use Efficiency, and Nitrogen Management
TLDR
The magnitude of the scientific challenge should not be underestimated because it becomes increasingly difficult to control the fate of N in cropping systems that must sustain yield increases on the world's limited supply of productive farm land. Expand

TLDR
This report provides a direct evidence of decreased rice yields from increased nighttime temperature associated with global warming and a close linkage between rice grain yield and mean minimum temperature during the dry cropping season. Expand

TLDR
It is concluded that major scientific breakthroughs must occur in basic plant physiology, ecophysiology, agroecology, and soil science to achieve the ecological intensification that is needed to meet the expected increase in food demand. Expand
Crop yield gaps: their importance, magnitudes, and causes.
Future trajectories of food prices, food security, and cropland expansion are closely linked to future average crop yields in the major agricultural regions of the world. Because the maximum possibleExpand
Nitrogen uptake, fixation and response to fertilizer N in soybeans: A review
Abstract Although relationships among soybean (Glycine max [L.] Merr) seed yield, nitrogen (N) uptake, biological N2 fixation (BNF), and response to N fertilization have received considerableExpand
Yield gap analysis with local to global relevance—A review
a b s t r a c t Yields of crops must increase substantially over the coming decades to keep pace with global food demand driven by population and income growth. Ultimately global food productionExpand
Annual carbon dioxide exchange in irrigated and rainfed maize-based agroecosystems
Carbon dioxide exchange was quantified in maize‐soybean agroecosystems employing year-round tower eddy covariance flux systems and measurements of soil C stocks, CO2 fluxes from the soil surface,Expand
Agricultural expansion and its impacts on tropical nature.
TLDR
Key priorities are to improve technologies and policies that promote more ecologically efficient food production while optimizing the allocation of lands to conservation and agriculture. Expand
Meeting Cereal Demand While Protecting Natural Resources and Improving Environmental Quality
▪ Abstract Agriculture is a resource-intensive enterprise. The manner in which food production systems utilize resources has a large influence on environmental quality. To evaluate prospects forExpand
