A proposed impact assessment method for genetically modified plants (AS-GMP Method).

An essential step in the development of products based on biotechnology is an assessment of their potential economic impacts and safety, including an evaluation of the potential impact of transgenic crops and practices related to their cultivation on the environment and human or animal health. The purpose of this paper is to provide an assessment method to evaluate the impact of biotechnologies that uses quantifiable parameters and allows a comparative analysis between conventional technology and technologies using GMOs. This paper introduces amethod to performan impact analysis associatedwith the commercial release and use of genetically modified plants, the Assessment SystemGMPMethod. The assessment is performed through indicators that are arranged according to their dimension criterion likewise: environmental, economic, social, capability and institutional approach. To perform an accurate evaluation of the GMP specific indicators related to genetic modification are grouped in common fields: genetic insert features, GMplant features, gene flow, food/feed field, introduction of the GMP, unexpected occurrences and specific indicators. The novelty is the possibility to include specific parameters to the biotechnology under assessment. In this case by case analysis the factors ofmoderation and the indexes are parameterized to perform an available assessment.

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.

Impacto da agricultura intensiva de cana-de-açúcar sobre as propriedades do solo e da água subterrânea - estudo de caso em Ribeirão Preto - SP.

A agricultura brasileira tem se destacado, entre as demais, pelo uso indiscriminado de insumos, contribuindo sistematicamente para o desequilíbrio do agroecossistema. Nas áreas de cultivo intensivo, particularmente naquelas com a monocultura de cana-de-açúcar, e intensa a utilização de maquinas e agroquímicos que intervêm de maneira quantitativa e qualitativa nos meios biótico, físico e químico do agroecossistema. A avaliação do efeitos provocados pelas atividades agrícolas no próprio meio (fatores intrínsecos) e no meio externo (fatores extrínsecos) requer a aplicação de metodologia que estabeleça uma relação casual entre a ação "potencialmente poluidora" e a degradação efetivamente verificada. Nesse contexto, adotou-se uma microbacia de uso agrícola intensivo na região de Ribeirão Preto - SP, onde há facilidade de compatibilização das variáveis dentro do sistema, condição que permite a compreensão das interações dos elementos entre si e com o todo, servindo de modelo para estudo de áreas análogas. A região de Ribeirão Preto e abastecida com água proveniente de mananciais subterrâneos vulneráveis, como é o caso do aquífero Botucatu. Em decorrência desse fato, tornam-se relevantes os aspectos relacionados à qualidade da água dos lençóis subterrâneos e as práticas agrícolas adotadas na região. Um diagnóstico socioeconômico se constitui em ferramenta importante na caracterização dos sistema de produção em uso na área, podendo orientar as demais atividades de pesquisa, estabelecendo-se épocas de coletas de água e solo para analise. O presente trabalho pretende desenvolver metodologia de avaliação de impacto ambiental em microbacias, aplicando o conhecimento da realidade, e propor a adoção de medidas mitigadoras ou preventivas de contaminação e ainda a orientação de políticas públicas para o setor.
