O presente boletim agrometeorológico tem por objetivo fornecer informações relevantes e consolidadas para dar suporte ao setor produtivo de Mato Grosso no sentido do acompanhamento das condições de chuva e déficit hídrico nas regiões produtoras do estado. Importante destacar que, considerando a escala de análise e dado o fator de variabilidade das precipitações e condições de seca, é necessário cautela na interpretação das informações aqui apresentadas. As informações deste boletim são fundamentadas em fontes de dados da Embrapa (Agritempo), CPTEC/INPE (Centro de Previsão de Tempo e Estudos Climáticos) e do INMET (Instituto Nacional de Meteorologia). |

Economic uncertainties and environmental constraints regarding fossil fuels have encouraged initiatives for renewable energy sources and assessment of their life cycle impacts. Brazil ranks second worldwide in biodiesel production, despite the relatively recent organization of its national chain, marked by the creation of the National Program for Biodiesel Production and Use (PNPB). The Central-West region is responsible for the largest share of biodiesel production (44.4%) and the largest cattle slaughter (37.5%). In this scenario, beef tallow has great potential for expansion of biodiesel production, since it is a byproduct of the chain that, when not properly disposed, presents a considerable environmental burden. This work presents a method for assessing environmental performance that integrates life cycle assessment (LCA) with land use change (LUC) for analysis of the tallow biodiesel production chain. The results are given in terms of increment in annual greenhouse gases (GHG) emissions per hectare related to local tallow biodiesel. The system's boundary covers a representative major cattle farming area in Central-West Brazil. For the LCA segment of the method, five inventory allocations were considered: (i) without allocation, (ii) mass, (iii) market value, (iv) energy and (v) an ?average allocation?, calculated as the mean of mass, market value and energy. The last one is a novel approach proposed in this work, aggregating all the others, which separately result in under or over estimation of impacts. Using the ?average allocation?, the increment in annual GHG emission per hectare from tallow biodiesel production, is 43.2 kg CO2eq ha-1 y-1. This value is 17% less than the emission increment due to soybean biodiesel (50.2 kg CO2eq ha-1 y-1). LUC is responsible for 96% of the emission assessed, which demonstrates the importance of including LUC assessment in life cycle assessment of tallow biodiesel. According to the sensitivity analyses performed, changes from crop to pasture have superior environmental performance among the investigated options. Land use management is essential to preserve the remaining natural areas, making tallow biodiesel more sustainable MenosEconomic uncertainties and environmental constraints regarding fossil fuels have encouraged initiatives for renewable energy sources and assessment of their life cycle impacts.
