Background: Given the importance of the agricultural activity for the economic development of the state of Rio de Janeiro, Brazil, in this paper we assess the effect of the environmental parameters related to soils and socioeconomic factors on the performance of the municipalities. Objective: To identify factors that influence on agricultural production performance, as well as the directions of such influences (positive or negative). Methodology: A two-stage Data Envelopment Analysis (DEA) was chosen for this analysis. The performance scores are computed considering land, labor, and capital (or technology) as inputs, and the value of crops and of livestock production as outputs. Results: The average efficiency was 0.5509 and 12 municipalities out of the 89 assessed were 100% efficient. A high level of susceptibility to erosion significantly and negatively influences the efficiency scores. The suitability of land for agriculture and for livestock are positively associated with performance. The presence of family-based farmers favors the agricultural performance of the assessed municipalities. Implications: These results may support public policies related to land use and soil governance. Conclusions: The proposed two-stage DEA approach was useful to assess the influence of factors related to soils and socioeconomic indicators on the agricultural performance of the municipalities in the state of Rio de Janeiro. |

Abstract. Bioenergy from sugarcane production is considered a key mitigation strategy for global warming. Improving its representation in land surface models is important to further understand the interactions between climate and bioenergy production, supporting accurate climate projections and decision-making. This study aimed to calibrate and evaluate the Joint UK Land Environment Simulator (JULES) for climate impact assessments in sugarcane. A dataset composed of soil moisture, water and carbon fluxes and biomass measurements from field experiments across Brazil was used to calibrate and evaluate JULES-crop and JULES-BE parametrisations. The ability to predict the spatiotemporal variability of sugarcane yields and the impact of climate change was also tested at five Brazilian microregions. Parameters related to sugarcane allometry, crop growth and development were derived and tested for JULES-crop and JULES-BE, together with the response to atmospheric carbon dioxide, temperature and drought (CTW-response). Both parametrisations showed comparable performance to other sugarcane dynamic models, with an RMSE of 6.75 and 6.05 t ha-1 for stalk dry matter for JULES-crop and JULES-BE, respectively. The parametrisations were also able to replicate the average yield patterns observed in the five microregions over 30 years when the yield gap factors were taken into account, with the correlation (r) between simulated and observed interannual variability of yields ranging from 0.33 to 0.56. An overall small positive trend was found in future yield projections of sugarcane using the new calibrations, with exception of the Jataí mesoregion which showed a clear negative trend for the SSP5 scenario from the year 2070 to 2100. Our simulations showed that an abrupt negative impact on sugarcane yields is expected if daytime temperatures above 35 oC become more frequent. The newly calibrated version of JULES can be applied regionally and globally to help understand the interactions between climate and bioenergy production. MenosAbstract.
