Towards actionable research frameworks for sustainable intensification in high-yielding rice systems.

ABSTRACT: New research frameworks that simultaneously address production and environmental goals are required to identify promising sustainable intensification options in high-yielding cereal systems. Here we estimated potential changes in environmental footprint associated with crop management practices aimed at breaking the yield ceiling for rice production in Uruguay. Results from a regional survey were combined with field experiments to integrate impacts on productivity and sustainability at two different intensification levels (average-yielding and high-yielding). Survey results indicate that high-yielding farmers produced 14% more grain compare to the regional average (7900 kg ha^-1), with 25% to 99% lower agrochemical contamination risk and similar nitrogen use efficiency and carbon
