Territorios y mercados globales: Las firmas agroexportadoras citrícolas del noreste argentino

El trabajo aborda la problemática de las firmas empacadoras/exportadoras de cítricos dulces del denominado corredor citrícola del río Uruguay -departamentos de Federación y Concordia en la provincia de Entre Ríos y departamento de Monte Caseros en Corrientes-. Específicamente nos preguntamos si la convergencia geográfica de firmas en un mismo espacio regional/local propicia mecanismos de articulación que favorezcan la obtención de sinergias y su participación en el segmento exportador, considerándolas en relación al capital trasnacional que opera en la misma región. En nuestro análisis exploramos algunas de las estrategias que adoptan las firmas para la inserción en los mercados, enfocándonos en los mecanismos de coordinación interempresarial a nivel horizontal y a escala local-regional, prestando particular atención a la sustentabilidad de los mismos. Empleamos un enfoque metodológico que pone énfasis en técnicas de análisis cualitativas, aplicadas a entrevistas semi-estructuradas y en profundidad a los integrantes de la trama, seleccionados en función del rol que cumplen dentro de ella. La información relevada se complementa con datos secundarios y la revisión de bibliografía pertinente para el área de estudio.

Os resultados apontaram que, na implementação das políticas estudadas neste trabalho, a gestão de redes influencia positivamente o alcance efetivo dos seus objetivos e constitui-se em uma ferramenta de apoio extremamente forte, tendo uma importância de destaque entre os fatores que impulsionam o desenvolvimento.

Effects of local and regional factors on the fish assemblage structure in Meridional Amazonian streams

The aim of this study was to evaluate the effects of local, regional and temporal factors structuring fish assemblages in Meridional Amazonian streams during the months of May (rainy season) and August (dry season) of 2008. To accomplish this task, 14 streams located in Serra do Expedito (Aripuanã River basin) were sampled along 30-m stretches. A total of 3,212 specimens distributed among five orders, 18 families, and 55 species were recorded. The fish assemblage structure in the streams presented variation among types of riparian vegetation (local factor) and watersheds (regional factor), but did not present variation between seasons (temporal factor) and stream order (regional factor). Larger streams with margins covered with pasture presented higher species richness and abundance than smaller streams with margins covered with forest. © 2012 Springer Science+Business Media B.V.

Trabalhadoras e economia solidária na associação de mulheres do município de Igarapé-Miri/Asmim-Pará: da resistência à estratégia de desenvolvimento local

O presente estudo retrata a constituição da Associação de Mulheres do Município de Igarapé-Miri –ASMIM/Pará, como um espaço de lutas, resistências e associativismo de mulheres trabalhadoras. Visa contribuir com o debate acerca das conquistas de uma experiência prática coletiva, na construção do desenvolvimento local, em Igarapé-Miri. Para isso, procurou-se nesta pesquisa entender o cenário da economia solidária, bem como, as diferentes concepções que giram em torno dessa temática em interface com o desenvolvimento local, à medida que, se entende ambas, como estratégias importantes para a constituição da mulher enquanto um sujeito coletivo capaz de romper com a invisibilidade e empoderar-se, no sentido de se tornar protagonista de sua própria história. Ressaltou-se importantes momentos de lutas e resistências femininas em torno de igualdade de direitos, geração de renda e participação na vida pública. Nesse sentido, a ênfase das organizações e movimentos sociais aos quais essas mulheres estiveram/estão articuladas foi importante para compreender de que forma elas foram galgando seu espaço de representação política em nível local, regional e nacional, ou seja, demonstrando novas práticas sócio-econômicas e político-culturais em que se tornaram referências e alteram a realidade do seu papel na sociedade contemporânea. Por fim, realçou-se que essa construção em Igarapé-Miri foi/é de muitas lutas, e, por conseguinte, conflitos que se expressam em âmbito familiar e de trabalho evidenciando desigualdades existentes e, muitas vezes, escamoteadas. Esta pesquisa traz para o debate os princípios de economia solidária, enquanto ambiente propício ao empoderamento das mulheres, de estratégia para um desenvolvimento local e de visibilidade pública para essas mulheres.

Los sistemas locales como instrumento en la construcción de estrategias de desarrollo regional local, en la política de descentralización de la gestión pública y participación ciudadana, el caso Chalatenango.

El desarrollo local, la crisis del Estado centralizado en muchos países del mundo y en especial América Latina, su correspondiente reforma, la descentralización, la participación ciudadana y el diseño de nuevas formas de agrupación y asociación así como nuevas figuras o modalidades de gestión de lo público, son temas de actualidad en la gran mayoría de gobiernos latinoamericanos. En El Salvador, desde hace un buen tiempo se vienen discutiendo estos y otros temas de interés con el objeto de lograr eficiencia y eficacia en la gestión pública. Como resultado de esas discusiones, se han ido conformando y estructurando diversos mecanismos en el esfuerzo de corresponder desde lo local a una verdadera reforma del Estado Salvadoreño. Es así como existen experiencias de desarrollo local muy interesantes en muchos departamentos y municipios como los casos de Nejapa, Acajutla, Suchitoto, Tecoluca, así como experiencias de mecanismos locales de desarrollo en Morazán, Cabañas, Cuscatlán y Chalatenango. Precisamente en este departamento es donde se dan las primeras experiencias en materia de mecanismos locales de concertación y desarrollo local en El Salvador. Esta investigación tiene como objetivos fundamentales: describir, analizar y sistematizar la experiencia que en materia de Sistemas Locales de Desarrollo se ha llevado a cabo, acumulado y consolidado en el departamento de Chalatenango, experiencia que se le propone a la institucionalidad del resto del país como modelo a tomar en cuenta como instrumentos hacia el desarrollo local y participación ciudadana, y que a partir de la misma se puedan plantear una serie de lineamientos que deben ser considerados en una propuesta de descentralización y desarrollo regional/local, así como identificar los posibles escenarios o dimensiones (local, territorial, microregional y regional ) en las que se puede ejecutar dicha propuesta; escenarios que son identificados por los propios actores locales, a partir de un diagnóstico de los mecanismos abordados en esta investigación. Dado el contenido de la investigación, se considera que no es posible realizar un estudio documental-bibliográfico, y una investigación de campo aisladas entre sí. Por lo tanto, la metodología de investigación que se utilizó fue de carácter mixto (documentalbibliográfico y de campo a la vez) y de tipo descriptiva. Las principales conclusiones y recomendaciones que se plasman en esta investigación son el resultado de un diagnostico a los mecanismos locales de concertación estudiados en el departamento de Chalatenango, entre las que se destacan las siguientes: En lo referente a definir una figura territorial: ninguno de los actores locales abordados se atreve a inclinarse por una figura territorial o una dimensión territorial específica para iniciar un esfuerzo por la construcción de estrategias de desarrollo para el Departamento. Son de la idea que ninguna figura puede desecharse y que por el contrario, deben complementarse unas con otras en tiempo y espacio; coinciden junto con otros actores locales e institucionales que en el marco de la planificación territorial, es la Mancomunidad la figura más idónea para iniciar un proceso de desarrollo local de corto y mediano plazo, pero que si se quiere profundizar en auténticas estrategias de desarrollo regional/local, es la Microregión la figura que más se adaptaría a las condiciones de Chalatenango; concluyen que la Mancomunidad Municipal constituye una estrategia de desarrollo local/regional ya que la visualizan como una transición de lo local (Mancomunidad Municipal) a lo regional (Microregión) en un marco de complementariedad y horizontalidad institucional. En esa misma dirección, visualizan al CACH y los demás mecanismos estudiados (SILDES), como estrategias de desarrollo sectorial que puede articularse a una estrategia de desarrollo departamental mucho más amplia y representativa como la CODDICH y que esta puede llegar a constituirse en la instancia intermedia o el interlocutor entre el gobierno central y el gobierno local; y en el mecanismo de consulta y propuesta para la construcción de la estrategia de desarrollo local para el Departamento en el largo plazo.Concluyen que la creación y consolidación de estos mecanismos ha contribuido y constituido la base para la implementación de estrategias de desarrollo concertadas y participativas en el esfuerzo de corresponder a una política de descentralización eficiente y eficaz en el manejo de la gestión pública, encaminada a la creación y definición de estrategias de desarrollo local y regional en el Departamento; se concluye que el Sistema Local de Desarrollo (SILDE) aún no está completo, que se va por buen camino pero que debe de seguirse construyendo ese sistema; se debe madurar y reflexionar sobre lo hecho hasta el momento, corregir las situaciones que han provocado debilidades institucionales y pérdida de credibilidad en algunos momentos ya que sólo de esta manera se podrá consolidar en el mediano y largo plazo un auténtico Sistema Local de Desarrollo en el departamento de Chalatenango. Finalmente, en base al diagnóstico presentado, se recomienda a los mecanismos estudiados retomar las observaciones plasmadas en él, tanto de cara a las fortalezas y oportunidades detectadas como aquellas áreas donde fueron identificadas situaciones de debilidades y potenciales amenazas institucionales. A partir de lo acumulado y realizado a la fecha en materia de Sistemas Locales de Desarrollo (SILDES) en el Departamento, se recomienda retomar y discutir los lineamientos propuestos en esta investigación, como un aporte complementario a fortalecer la experiencia local en Chalatenango, indicando que no es una propuesta terminada y cerrada a la inclusión de otros puntos trascendentales para el departamento y para el país; continuar profundizando la temática, particularmente en lo referente a la reforma del Estado, la descentralización y a la conformación de nuevas figuras de administración para volver eficiente y eficaz los procesos de desarrollo local y territorial.

Towards local cultures of sustainability : facilitating community created environment education centres through design

Ecological sustainability has been proposed to address the problem of human impacts increasingly degrading planetary resources and ecosystems, threatening biodiversity, eco-services and human survival. Ecological sustainability is an imperative, with Australia having one of the highest eco-footprints per person worldwide. While significant progress has been made via implementation of ecologically sustainable design in urban communities, relatively little has been undertaken in small, disparate regional communities in Australia. Regional communities are disadvantaged by rural economic decline associated with structural change and inequities of resource transfer. The ecologically sustainable solution is holistic, so all settlements need to be globally wise, richly biodiverse yet locally specific. As a regional solution to this global problem, this research offers the practical means by which a small regional community can contribute. It focuses on the design and implementation of a community centre and the fostering of transformative community learning through an integrated ‘learning community’ awareness of ecologically sustainable best practice. Lessons learned are documented by the participant researcher who as a designer, facilitator, local resident and social narrator has been deeply connected with the Tweed-Caldera region over a period since 1980. The collective action of the local community of Chillingham has been diligently recorded over a decade of design and development. Over this period, several positive elements emerged in terms of improvements to the natural and built environment, greater social cohesion and co-operative learning along with a shift towards a greener local economy. Behavioural changes in the community were noted as residents strived to embrace ecological ideals and reduce fossil fuel dependency. They found attractive local solutions to sourcing of food and using local employment opportunities to up skill their residents via transformative learning as a community in transition. Finally, the catalytic impact of external partnering has also been documented. How well the region as a whole has achieved its ecologically sustainable objectives is measured in terms of the delivered success of private and public partnering with the community, the creation of a community centre cum environment education centre, the restoration of local heritage buildings, the repair of riparian forests and improved water conditions in local river systems, better roads and road safety, local skills and knowledge transfer, support of local food and local/regional growers markets to attract tourists via the integrated trails network. In aggregate, each and every element contributes to a measure of eco-positive development for the built environment, its social organisation and its economy that has guided the local community to find its own pathway to sustainability. Within the Tweed-Caldera bioregion in northern New South Wales, there has been a lack of strategic planning, ecologically sustainable knowledge and facilities in isolated communities that could support the development of a local sustained green economy, provide a hub for socio-cultural activities and ecology based education. The first challenge in this research was to model a whole systems approach to eco-positive development in Chillingham, NSW, a small community where Nature and humanity know no specific boundary. The net result was the creation of a community environment education centre featuring best-affordable ecological practice and regionally distinctive, educational building form from a disused heritage building (cow bale). This development, implemented over a decade, resonated with the later regional wide programs that were linked in the Caldera region by the common purpose of extending the reach of local and state government assistance to regional NSW in economic transition coupled with sustainability. The lessons learned from these linked projects reveal that subsequent programs have been significantly easier to initiate, manage, develop and deliver results. In particular, pursuing collaborative networks with all levels of government and external private partners has been economically effective. Each community’s uniqueness has been celebrated and through drawing out these distinctions, has highlighted local vision, strategic planning, sense of belonging and connection of people with place. This step has significantly reduced the level of friction between communities that comes from natural competition for the finite pool of funds. Following the pilot Tweed-Caldera study, several other NSW regional communities are now undertaking a Community Economic Transition Program based on the processes, trials and positive experiences witnessed in the Tweed-Caldera region where it has been demonstrated that regional community transition programs can provide an opportunity to plan and implement effective long term strategies for sustainability, empowering communities to participate in eco-governance. This thesis includes the design and development of a framework for community created environment education centres to provide an equal access place for community to participate to meet their essential needs locally. An environment centre that facilitates community transition based on easily accessible environmental education, skills and infrastructure is necessary to develop local cultures of sustainability. This research draws upon the literatures of ecologically sustainable development, environmental education and community development in the context of regional community transition towards ‘strong sustainability’. The research approach adapted is best described as a four stage collaborative action research cycle where the participant researcher (me) has a significant involvement in the process to foster local cultures of sustainability by empowering its citizens to act locally and in doing so, become more self reliant and socially resilient. This research also draws upon the many fine working exemplars, such as the resilience of the Cuban people, the transition town initiative in Totnes, U.K. and the models of Australian Community Gardens, such as CERES (Melbourne) and Northey Street (Brisbane). The objectives of this study are to research and evaluate exemplars of ecologically sustainable environment education centres, to facilitate the design and development of an environment education centre created by a small regional community as an ecologically sustainable learning environment; to facilitate a framework for community transition based on environmental education, skills and infrastructure necessary to develop local cultures of sustainability. The research was undertaken as action research in the Tweed Caldera in Northern NSW. This involved the author as participant researcher, designer and volunteer in two interconnected initiatives: the Chillingham Community Centre development and the Caldera Economic Transition Program (CETP). Both initiatives involved a series of design-led participatory community workshops that were externally facilitated with the support of government agency partnerships, steering committees and local volunteers. Together the Caldera research programs involved communities participating in developing their own strategic planning process and outcomes. The Chillingham Community Centre was developed as a sustainable community centre/hub using a participatory design process. The Caldera Economic Transition Program (CETP) prioritised Caldera region projects: the Caldera farmer’s market; community gardens and community kitchens; community renewable energy systems and an integrated trails network. The significant findings were: the CETP projects were capable of moving towards an eco-positive design benchmark through transformative learning. Community transition to sustainability programs need to be underpinned by sustainability and environmental education based frameworks and practical on ground experience in local needs based projects through transformative learning. The actioned projects were successfully undertaken through community participation and teamwork. Ecological footprint surveys were undertaken to guide and assess the ongoing community transition process, however the paucity of responses needs to be revisited. The concept of ecologically sustainable development has been adopted internationally, however existing design and planning strategies do not assure future generations continued access to healthy natural life support systems. Sustainable design research has usually been urban focussed, with little attention paid to regional communities. This study seeks to redress this paucity through the design of ecologically sustainable (deep green) learning environments for small regional communities. Through a design-led process of environmental education, this study investigates how regional communities can be facilitated to model the principles of eco-positive development to support transition to local cultures of sustainability. This research shows how community transition processes and projects can incorporate sustainable community development as transformative learning through design. Regional community transition programs can provide an opportunity to plan long term strategies for sustainability, empowering people to participate in eco-governance. A framework is developed for a community created environment education centre to provide an equal access place for the local community to participate in implementing ways to meet their essential needs locally. A community environment education centre that facilitates community transition based on holistic environmental education, skills and infrastructure is necessary to develop local cultures of sustainability.

Integration of natural hazards, risk and climate change into spatial planning practices

Most countries of Europe, as well as many countries in other parts of the world, are experiencing an increased impact of natural hazards. It is often speculated, but not yet proven, that climate change might influence the frequency and magnitude of certain hydro-meteorological natural hazards. What has certainly been observed is a sharp increase in financial losses caused by natural hazards worldwide. Eventhough Europe appears to be a space that is not affected by natural hazards to such catastrophic extents as other parts of the world are, the damages experienced here are certainly increasing too. Natural hazards, climate change and, in particular, risks have therefore recently been put high on the political agenda of the EU. In the search for appropriate instruments for mitigating impacts of natural hazards and climate change, as well as risks, the integration of these factors into spatial planning practices is constantly receiving higher attention. The focus of most approaches lies on single hazards and climate change mitigation strategies. The current paradigm shift of climate change mitigation to adaptation is used as a basis to draw conclusions and recommendations on what concepts could be further incorporated into spatial planning practices. Especially multi-hazard approaches are discussed as an important approach that should be developed further. One focal point is the definition and applicability of the terms natural hazard, vulnerability and risk in spatial planning practices. Especially vulnerability and risk concepts are so many-fold and complicated that their application in spatial planning has to be analysed most carefully. The PhD thesis is based on six published articles that describe the results of European research projects, which have elaborated strategies and tools for integrated communication and assessment practices on natural hazards and climate change impacts. The papers describe approaches on local, regional and European level, both from theoretical and practical perspectives. Based on these, passed, current and future potential spatial planning applications are reviewed and discussed. In conclusion it is recommended to shift from single hazard assessments to multi-hazard approaches, integrating potential climate change impacts. Vulnerability concepts should play a stronger role than present, and adaptation to natural hazards and climate change should be more emphasized in relation to mitigation. It is outlined that the integration of risk concepts in planning is rather complicated and would need very careful assessment to ensure applicability. Future spatial planning practices should also consider to be more interdisciplinary, i.e. to integrate as many stakeholders and experts as possible to ensure the sustainability of investments.

Exploring use of climate information for optimal design of water resources infrastructure

We conducted surveys of fire and fuels managers at local, regional, and national levels to gain insights into decision processes and information flows in wildfire management. Survey results in the form of fire managers’ decision calendars show how climate information needs vary seasonally, over space, and through the organizational network, and help determine optimal points for introducing climate information and forecasts into decision processes. We identified opportunities to use climate information in fire management, including seasonal to interannual climate forecasts at all organizational levels, to improve the targeting of fuels treatments and prescribed burns, the positioning and movement of initial attack resources, and staffing and budgeting decisions. Longer-term (5–10 years) outlooks also could be useful at the national level in setting budget and research priorities. We discuss these opportunities and examine the kinds of organizational changes that could facilitate effective use of existing climate information and climate forecast capabilities.

Predictive Factors for Local Control in Primary and Metastatic Lung Tumours after Four to Five Fraction Stereotactic Ablative Body Radiotherapy: A Single Institution's Comprehensive Experience

AIMS: We report the outcomes of a large lung stereotactic ablative body radiotherapy (SABR) programme for primary non-small cell lung cancer (NSCLC) and pulmonary metastases. The primary study aim was to identify factors predictive for local control.

MATERIALS AND METHODS: In total, 311 pulmonary tumours in 254 patients were treated between 2008 and 2011 with SABR using 48-60 Gy in four to five fractions. Local, regional and distant failure data were collected prospectively, whereas other end points were collected retrospectively. Potential clinical and dosimetric predictors of local control were evaluated using univariate and multivariate analyses.

RESULTS: Of the 311 tumours, 240 were NSCLC and 71 were other histologies. The 2 year local control rate was 96% in stage I NSCLC, 76% in colorectal cancer (CRC) metastases and 91% in non-lung/non-CRC metastases. Predictors of better local control on multivariate analysis were non-CRC tumours and a larger proportion of the planning target volume (PTV) receiving ≥100% of the prescribed dose (higher PTV V100). Among the 45 CRC metastases, a higher PTV V100 and previous chemotherapy predicted for better local control.

CONCLUSIONS: Lung SABR of 48-60 Gy/four to five fractions resulted in high local control rates for all tumours except CRC metastases. Covering more of the PTV with the prescription dose (a higher PTV V100) also resulted in superior local control.
