Evaluating social and environmental impacts at Embrapa.

A strategic planning process has been implemented at the Brazilian Agricultural Research Agency (Embrapa) to introduce sustainable development objectives in all steps of agricultural Research and Development. An essential component of the institutional mission statement hence devised has called for the systematic assessment of social and environmental impacts (in addition to the traditionally studied economic ones) of all technology innovations resulting from R&D. The proposed approach emphasizes the interest of promoting close interaction between R&D teams and technology-adopting producers, under actual field contexts, in order to improve both the technology development and the demand probing processes. Given the multiplicity of technological applications ensuing from Embrapa?s very broad research encompassment, and the variety of environmental and productive contexts involved, a customized impact assessment system has been proposed. Directed at the appraisal of agricultural technology development research projects (ex-ante) as well as their ensuing innovations (ex-post), the Ambitec-Agro System comprises a set of integrated socio-environmental indicators, constructed in modules suited to Agricultural, Animal husbandry, and Agro-industrial activities, besides a specific module for Social Impact Assessment. The system has been routinely applied in technology appraisal in all of Embrapa?s Units, as a basis for their institutional performance evaluations, and toward the formulation of the annual Social Balance Report. Following the inception of this institutional technology appraisal initiative, several methodological innovations have been proposed within Embrapa, including technical improvements and applicability adaptations of the Ambitec-Agro system, and approaches to further-reaching objectives, such as the sustainable development of rural communities, and the environmental management of agricultural activities.

Avaliação do ciclo de vida do sistema de produção soja-girassol no cerrado Brasileiro.

RESUMO: O girassol é uma importante cultura na região de Parecis, no Cerrado brasileiro. Em 2014, a região respondeu pela produção de 232.700 t de grãos, 45% da produção nacional. A produção de girassol provém principalmente de um sistema que tem a soja como cultura principal. A associação entre soja e girassol pode reduzir impactos ambientais devido ao uso compartilhado de recursos. Este estudo desenvolveu uma Avaliação de Ciclo de Vida (ACV) ?do berço ao túmulo? do sistema de produção soja-girassol usado na região de Parecis e comparou seu perfil ambiental ao das monoculturas de soja e girassol. Impactos relacionados ao uso do solo (emissões da mudança de uso da terra e calagem) por cada cultura foram alocados em função do tempo de ocupação do solo. O sistema soja-girassol teve impactos ambientais menores em todas as categorias de impacto quando comparado à monocultura de soja e girassol, com o mesmo rendimento. Reduções importantes foram observadas em ?Mudança do Clima?, ?Acidificação Terrestre? e ?Formação de Material Particulado?. ABSTRACT: Sunflower is an important crop in Parecis region of the Brazilian Cerrado. In 2014 the region accounted for the production of 232,700 tons of sunflower grain, 45% of national production. Sunflower production comes mostly from a system that has soybean as the main crop. The association of soybean and sunflower can reduce environmental impacts due to shared use of resources. This study performed a ?cradle to gate? Life Cycle Assessment (LCA) of the soybean-sunflower production system used in Parecis region and compared its environmental profile to that of the monoculture of these two crops. Impacts related to the use of soil (land use change emissions and liming) by each crop were evaluated according to time of soil occupation criterion. Soybean-sunflower system had lower environmental impacts on every impact category comparing to soybean and sunflower monoculture with the same yield. Important reduction were observed on ?Climate change?, ?Terrestrial acidification? and ?Particulate matter formation? categories.
