A major question facing global rice systems is the extent to which yield and resource use efficiency indicators can be simultaneously optimized to sustainably meet future food demand. However, research approaches for evaluating synergies and tradeoffs among multiple indicators have been limited to date. Using the case study of rice production in Uruguay, we quantified five cropping system performance indicators at the farm-level from 2012 to 2017, covering approximately 40% of national rice area. Results suggest that maximizing performance in one
indicator is associated with tradeoffs for other indicators, with no farm simultaneously ranking as a topperformer (defined as top 10% of farms) across all indicators. The gaps between the average and topperforming farms were largest for agrochemical contamination risk (33%) and smallest for yield (11%). Comparing the groups of top-performing farms within each indicator revealed opportunities for improving system-level performance via synergistic effects between yield and resource use efficiencies, but not between carbon footprint, agrochemical contamination risk, and other indicators. Importantly, synergistic effects were more pronounced for farms at lower compared to higher productivity levels, suggesting less room for ustainability improvements at higher yield levels, unless yields can be further increased without elevated inputs. Important factors to improve the aggregated sustainability index included N fertilizer rate and seeding date. With potential application to rice production systems worldwide, this study highlights an integrated research approach for quantifying synergies and tradeoffs among multiple indicators to understand opportunities for increasing crop yields without negatively impacting resource use efficiency and environmental footprint.

ABSTRACT.
Atmospheric pollution related to gas emissions from livestock production has become an issue of increasing interest. International commitments bind countries to provide annual reports on national emissions, however there is a lack of information regarding the estimation of emissions from rabbit farms. There are several methodologies available to measure gas emissions, the flux chamber technique being one of the most commonly used. In this study, a flux chamber was designed to measure emissions from small farm animals and their manure, as well as the methodology to calculate ventilation fluxes appropriate for each experiment. After the chamber was constructed, two experiments were carried out to test its operation, design and construction. Firstly, carbon dioxide emissions from fattening rabbits were measured for 24 and 48 h. Emissions from fattening rabbit manure were then measured for one-hour periods. The operation of the flux chamber was satisfactory during both experiments and notes were taken of possible improvements in performance through future research. Recommendations for its use are also summarized.
