TL;DR: 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.
Journal ArticleDOI
Yield Trends Are Insufficient to Double Global Crop Production by 2050.
TL;DR: 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.

Closing yield gaps through nutrient and water management

TL;DR: A global-scale assessment of intensification prospects from closing ‘yield gaps’, the spatial patterns of agricultural management practices and yield limitation, and the management changes that may be necessary to achieve increased yields finds that global yield variability is heavily controlled by fertilizer use, irrigation and climate.
Journal ArticleDOI
Climate variation explains a third of global crop yield variability
TL;DR: This study uses detailed crop statistics time series for ~13,500 political units to examine how recent climate variability led to variations in maize, rice, wheat and soybean crop yields worldwide.
Journal ArticleDOI
Recent patterns of crop yield growth and stagnation
TL;DR: Although yields continue to increase in many areas, it is found that across 24-39% of maize-, rice-, wheat- and soybean-growing areas, yields either never improve, stagnate or collapse, which underscores the challenge of meeting increasing global agricultural demands.
