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
Closing yield gaps through nutrient and water management
Nathaniel D. Mueller,James S. Gerber,M. Johnston,Deepak K. Ray,Navin Ramankutty,Jonathan A. Foley +5 more
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
Leverage points for improving global food security and the environment

TL;DR: It is found that a relatively small set of places and actions could provide enough new calories to meet the basic needs for more than 3 billion people, address many environmental impacts with global consequences, and focus food waste reduction on the commodities with the greatest impact on food security.
Journal ArticleDOI
Redefining agricultural yields: from tonnes to people nourished per hectare
TL;DR: In this article, the authors re-examine agricultural productivity and find that growing food exclusively for direct human consumption could increase available food calories by as much as 70% which could feed an additional 4 billion people (more than the projected 2.3 billion people arriving through population growth).
