Applying a Systems Approach to the Analysis of the Benefits of Conversion to Organic Production

Although the current level of organic production in industrialised countries amounts to little more than 1-2 percent, it is recognised that one of the major issues shaping agricultural output over the next several decades will be the demand for organic produce (Dixon et al. 2001). In Australia, the issues of healthy food and environmental concern contribute to increasing demand and market volumes for organic produce. However, in Indonesia, using more economical inputs for organic production is a supply-side factor driving organic production. For individual growers and processors, conversion from conventional to organic agriculture is often a challenging step, entailing a thorough revision of established practices and heightened market insecurity. This paper examines the potential for a systems approach to the analysis of the conversion process, to yield insights for household and community decisions. A framework for applying farming systems research to investigate the benefits of organic production in both Australia and Indonesia is discussed. The framework incorporates scope for farmer participation, crucial to the understanding of farming systems; analysis of production; and relationships to resources, technologies, markets, services, policies and institutions in their local cultural context. A systems approach offers the potential to internalise the external effects that may be constraining decisions to convert to organic production, and for the design of decision-making tools to assist households and the community. Systems models can guide policy design and serve as a mechanism for predicting the impact of changes to the policy and market environments. The increasing emphasis of farming systems research on community and environment in recent years is in keeping with the proposed application to organic production, processing and marketing issues. The approach will also facilitate the analysis of critical aspects of the Australian production, marketing and policy environment, and the investigation of these same features in an Indonesian context.

Recommendations for the viability assessment of probiotics as concentrated cultures and in food matrices

Due to the fact that probiotic cells need to be alive when they are consumed, culture-based analysis (plate count) is critical in ascertaining the quality (numbers of viable cells) of probiotic products. Since probiotic cells are typically stressed, due to various factors related to their production, processing and formulation, the standard methodology for total plate counts tends to underestimate the cell numbers of these products. Furthermore, products such as microencapsulated cultures require modifications in the release and sampling procedure in order to correctly estimate viable counts. This review examines the enumeration of probiotic bacteria in the following commercial products: powders, microencapsulated cultures, frozen concentrates, capsules, foods and beverages. The parameters which are specifically examined include: sample preparation (rehydration, thawing), dilutions (homogenization, media) and plating (media, incubation) procedures. Recommendations are provided for each of these analytical steps to improve the accuracy of the analysis. Although the recommendations specifically target the analysis of probiotics, many will apply to the analysis of commercial lactic starter cultures used in food fermentations as well.

Beneficiamento local da produção extrativista e agroflorestal: o caso da Cooperativa Agroextrativista de Xapuri – CAEX

O objetivo do artigo é analisar as dificuldades de consolidação econômica vivenciadas pela Cooperativa Agroextrativista de Xapuri – CAEX ao longo da sua existência. A Cooperativa fundada em 1988 por seringueiros do município de Xapuri, no estado do Acre, é um exemplo das dificuldades de implantação de um projeto de beneficiamento local da produção agro-extrativista. A proposta de agregar valor à produção dos cooperados através do beneficiamento da castanha-do-brasil apresentou resultados econômicos bem abaixo do esperado. Grande parte das análises existentes sobre essa situação isolam alguns aspectos sócio-econômicos da Cooperativa e enxergam neles as causas exclusivas dos seus problemas. Nesse trabalho utilizaram-se ferramentas conceituais da economia evolucionária o que permitiu o reconhecimento de problemas estruturais na experiência.

Modelamento de perfis de indução

Neste trabalho foi implementado um algoritmo que permite o modelamento das respostas das sondas de indução (2C40-6FF40-ILD) em meios estratificados. O algoritmo é baseado na solução exata do problema de Green para a obtenção do campo eletromagnético em meios estratificados com a fonte no interior dos estratos. O código computacional desenvolvido neste trabalho para meios horizontalmente estratificados tem o objetivo de auxiliar o desenvolvimento de códigos mais avançados, uma vez que é difícil o acesso para a pesquisa dos códigos citados na literatura. Os códigos disponíveis são comerciais, mas estes têm o objetivo único de produção, além de serem, bastante dispendiosos. O código também foi utilizado para a obtenção da resposta da sonda ILD em reservatórios do tipo laminado, onde a sonda tem baixa resolução. E verificamos, a exemplo de outros autores, que a condutividade obtida pela sonda pode ser expressa pela soma das condutividades dos constituintes litológicos do reservatório ponderada pelos seus percentuais em volume. Esta relação foi definida para reservatórios ainda não analisados na literatura, tipo arenito moderadamente silicificado/arenito/folhelho, onde a lâmina de interesse tem resistividade superior a resistividade de uma das lâminas, e inferior a resistividade da outra. Foi analisado também reservatórios tipo arenito moderadamente silicificado/arenito, onde a lâmina de interesse tem a menor resistividade. Com esta relação pode-se obter para estes reservatórios laminados estimativas mais precisas de Rt e consequentemente determinar as saturações água/óleo e produtibilidade, também de forma mais precisa.

Flow Field–Flow Fractionation for size analysis and characterization of nanoparticles for applications in Life Sciences

Nanotechnologies are rapidly expanding because of the opportunities that the new materials offer in many areas such as the manufacturing industry, food production, processing and preservation, and in the pharmaceutical and cosmetic industry. Size distribution of the nanoparticles determines their properties and is a fundamental parameter that needs to be monitored from the small-scale synthesis up to the bulk production and quality control of nanotech products on the market. A consequence of the increasing number of applications of nanomaterial is that the EU regulatory authorities are introducing the obligation for companies that make use of nanomaterials to acquire analytical platforms for the assessment of the size parameters of the nanomaterials. In this work, Asymmetrical Flow Field-Flow Fractionation (AF4) and Hollow Fiber F4 (HF5), hyphenated with Multiangle Light Scattering (MALS) are presented as tools for a deep functional characterization of nanoparticles. In particular, it is demonstrated the applicability of AF4-MALS for the characterization of liposomes in a wide series of mediums. Afterwards the technique is used to explore the functional features of a liposomal drug vector in terms of its biological and physical interaction with blood serum components: a comprehensive approach to understand the behavior of lipid vesicles in terms of drug release and fusion/interaction with other biological species is described, together with weaknesses and strength of the method. Afterwards the size characterization, size stability, and conjugation of azidothymidine drug molecules with a new generation of metastable drug vectors, the Metal Organic Frameworks, is discussed. Lastly, it is shown the applicability of HF5-ICP-MS for the rapid screening of samples of relevant nanorisk: rather than a deep and comprehensive characterization it this time shown a quick and smart methodology that within few steps provides qualitative information on the content of metallic nanoparticles in tattoo ink samples.

Understanding, defining and assessing food systems’ social and economic sustainability indicators: implementation of mixed methodologies for policy insights

Sustainability encompasses the presence of three dimensions that must coexist simultaneously, namely the environmental, social, and economic ones. The economic and social dimensions are gaining the spotlight in recent years, especially within food systems. To assess social and economic impacts, indicators and tools play a fundamental role in contributing to the achievements of sustainability targets, although few of them have deepen the focus on social and economic impacts. Moreover, in a framework of citizen science and bottom-up approach for improving food systems, citizen play a key role in defying their priorities in terms of social and economic interventions. This research expands the knowledge of social and economic sustainability indicators within the food systems for robust policy insights and interventions. This work accomplishes the following objectives: 1) to define social and economic indicators within the supply chain with a stakeholder perspective, 2) to test social and economic sustainability indicators for future food systems engaging young generations. The first objective was accomplished through the development of a systematic literature review of 34 social sustainability tools, based on five food supply chain stages, namely production, processing, wholesale, retail, and consumer considering farmers, workers, consumers, and society as stakeholders. The second objective was achieved by defining and testing new food systems social and economic sustainability indicators through youth engagement for informed and robust policy insights, to provide policymakers suggestions that would incorporate young generations ones. Future food systems scenarios were evaluated by youth through focus groups, whose results were analyzed through NVivo and then through a survey with a wider platform. Conclusion addressed the main areas of policy interventions in terms of social and economic aspects of sustainable food systems youth pointed out as in need of interventions, spanning from food labelling reporting sustainable origins to better access to online food services.
