“Law on Transboundary Movement of Hazardous Substances through Sea

This study pertain to legal control of pollution from transboundary movement of hazardous substances through sea. It is an emerging area in international maritime law. There is growing environmental awareness that oceans are no longer an inexhaustible resource. This has resulted in a complex system of integrated ocean policies and international legal frame work in this regard. Considering the peculiar nature of hazardous substances, the development of law in this regard has been haphazard. The legal framework in this area is not comprehensive and lacks coherence. India is geo-strategically located in the central part of Indian Ocean through which many international sea routes lie. India is also fast emerging as a maritime hub. Indian legal framework in this respect also suffers from serious pitfalls. In this backdrop, this study makes a sincere attempt to identify and analyse the legal intricacies in this area, in order to evolve a better regime for control of pollution pursuant to transboundary movement of hazardous substances through sea

Design, implementation and application of a generic framework for integrated regional land-use modeling

Land use is a crucial link between human activities and the natural environment and one of the main driving forces of global environmental change. Large parts of the terrestrial land surface are used for agriculture, forestry, settlements and infrastructure. Given the importance of land use, it is essential to understand the multitude of influential factors and resulting land use patterns. An essential methodology to study and quantify such interactions is provided by the adoption of land-use models. By the application of land-use models, it is possible to analyze the complex structure of linkages and feedbacks and to also determine the relevance of driving forces. Modeling land use and land use changes has a long-term tradition. In particular on the regional scale, a variety of models for different regions and research questions has been created. Modeling capabilities grow with steady advances in computer technology, which on the one hand are driven by increasing computing power on the other hand by new methods in software development, e.g. object- and component-oriented architectures. In this thesis, SITE (Simulation of Terrestrial Environments), a novel framework for integrated regional sland-use modeling, will be introduced and discussed. Particular features of SITE are the notably extended capability to integrate models and the strict separation of application and implementation. These features enable efficient development, test and usage of integrated land-use models. On its system side, SITE provides generic data structures (grid, grid cells, attributes etc.) and takes over the responsibility for their administration. By means of a scripting language (Python) that has been extended by language features specific for land-use modeling, these data structures can be utilized and manipulated by modeling applications. The scripting language interpreter is embedded in SITE. The integration of sub models can be achieved via the scripting language or by usage of a generic interface provided by SITE. Furthermore, functionalities important for land-use modeling like model calibration, model tests and analysis support of simulation results have been integrated into the generic framework. During the implementation of SITE, specific emphasis was laid on expandability, maintainability and usability. Along with the modeling framework a land use model for the analysis of the stability of tropical rainforest margins was developed in the context of the collaborative research project STORMA (SFB 552). In a research area in Central Sulawesi, Indonesia, socio-environmental impacts of land-use changes were examined. SITE was used to simulate land-use dynamics in the historical period of 1981 to 2002. Analogous to that, a scenario that did not consider migration in the population dynamics, was analyzed. For the calculation of crop yields and trace gas emissions, the DAYCENT agro-ecosystem model was integrated. In this case study, it could be shown that land-use changes in the Indonesian research area could mainly be characterized by the expansion of agricultural areas at the expense of natural forest. For this reason, the situation had to be interpreted as unsustainable even though increased agricultural use implied economic improvements and higher farmers' incomes. Due to the importance of model calibration, it was explicitly addressed in the SITE architecture through the introduction of a specific component. The calibration functionality can be used by all SITE applications and enables largely automated model calibration. Calibration in SITE is understood as a process that finds an optimal or at least adequate solution for a set of arbitrarily selectable model parameters with respect to an objective function. In SITE, an objective function typically is a map comparison algorithm capable of comparing a simulation result to a reference map. Several map optimization and map comparison methodologies are available and can be combined. The STORMA land-use model was calibrated using a genetic algorithm for optimization and the figure of merit map comparison measure as objective function. The time period for the calibration ranged from 1981 to 2002. For this period, respective reference land-use maps were compiled. It could be shown, that an efficient automated model calibration with SITE is possible. Nevertheless, the selection of the calibration parameters required detailed knowledge about the underlying land-use model and cannot be automated. In another case study decreases in crop yields and resulting losses in income from coffee cultivation were analyzed and quantified under the assumption of four different deforestation scenarios. For this task, an empirical model, describing the dependence of bee pollination and resulting coffee fruit set from the distance to the closest natural forest, was integrated. Land-use simulations showed, that depending on the magnitude and location of ongoing forest conversion, pollination services are expected to decline continuously. This results in a reduction of coffee yields of up to 18% and a loss of net revenues per hectare of up to 14%. However, the study also showed that ecological and economic values can be preserved if patches of natural vegetation are conservated in the agricultural landscape. -----------------------------------------------------------------------

Factors influencing a conversion to organic farming in Nepalese tea farms

Organic agriculture in developing countries has increased in past decades especially due to the high demand of organic products in developed countries. The rate of conversion to organic production in Nepal, however, is observed much slower than expected. This study investigates factors that determine the conversion to organic production using Nepalese tea producers as a case study. A survey of 181 farmers was conducted in the Ilam and Panchthar district of Nepal, among which 86 were organic farmers and 95 were conventional farmers. A discriminant analysis was used to identify socio-economic characteristics that distinguish conventional and organic farmers. Results from the estimated discriminant function suggest that farmers located in a distance from regional markets, older in age, better trained, affiliated with institutions and having larger farms are more likely to adopt organic production. Similarly, a factor analysis shows that environmental awareness, bright market prospects, observable economic benefit and health consciousness are the major factors influencing farmers’ decisions on the conversion to organic production. While planning programs for the development of the organic tea sector in Nepal, policy makers should consider the support of farmers’ institutions, provision of training to farmers and raise farmers’ awareness about the environmental, economic and health benefits of organic farming.

Análisis del contexto de oportunidades y restricciones políticas bajo el cual se ha llevado a cabo la movilización del pueblo Mapuche en Chile (2000-2010)

Monografía de grado por medio de la cual a partir de la teoría de Estructura de Oportunidades y de restricciones Políticas de Sydney Tarrow, se analiza el contexto en el que la movilización mapuche emergió durante los dos últimos gobiernos del partido socialista chileno. Para ello en un primer momento se hizo un análisis histórico de la problemática indígena hasta el restablecimiento de la democracia en 1989. Paso seguido fueron analizadas las respuestas que dieron los gobiernos de Ricardo Lagos y Michelle Bachelet a la problemática indígena y mapuche, teniendo como marco la reivindicación de derechos que les fueron planteadas a dichos gobiernos.

Análisis de la Cooperación Multilateral para la Gestión de biodiversidad en Instituciones Subregionales. Caso de Estudio: Estrategia regional para la conservación y uso Sostenible de recursos en el Amazonas (TCA) y Proyecto Facilitación de financiamiento para negocios de biodiversidad y apoyo al desarrollo de actividades del mercado en la Región Andina (CAN) 2000-2009

Este trabajo de investigación analiza la importancia de la cooperación internacional para la gestión de biodiversidad entregada por el Global Environmental Facilty-GEF, para la conservación y uso sostenible de la biodiversidad en la cuenca Andino-amazónica. Esto a través del estudio de los proyectos de alcance regional financiados a dos instituciones subregionales, el primero, “Estrategia Regional para la Conservación y Uso Sostenible de Recursos en el Amazonas” perteneciente al Tratado de Cooperación Amazónica-TCA, y el segundo, “Facilitación de Financiamiento para Negocios de Biodiversidad y Apoyo al Desarrollo de Actividades de Mercado en la Región Andina” presentado por la Banco de Desarrollo de América Latina-CAF.

Ayer mineros, hoy eco-guías y concesionarios: tensiones en torno a la conservación ambiental, el uso de la tierra y el trabajo en Guasca, Cundinamarca

En Guasca, Cundinamarca, se han configurado cambios profundos en el uso de los recursos naturales y el trabajo. En la misma área donde operó una mina de cal a cielo abierto por más de sesenta años, hoy en día existe una reserva biológica. Este proceso ha conllevado transformaciones y negociaciones entre las formas locales de uso de los recursos naturales y los usos propuestos por la conservación ambiental. Por su parte, el trabajo en la vereda se ha visto afectado por el cambio reciente en el usufructo de los recursos ambientales y las precariedades económicas del agro en Colombia. El argumento central de este texto es que la declaratoria de áreas protegidas privadas, como práctica suscrita al discurso ambientalista global, más que un proceso neutro, es una fuente de tensión constante entre pobladores locales y administradores de las zonas de conservación ecológica por cuenta del manejo territorial y ambiental, el entendimiento del uso de los recursos naturales y la naturaleza, la propiedad, el empleo y la descentralización del poder estatal. Así las cosas, este trabajo se preocupa por analizar las tensiones e implicaciones que supone la declaratoria de áreas protegidas para las poblaciones locales, en particular en su economía, trabajo y formas de apropiarse de la naturaleza y sus recursos.

Acción de organizaciones no gubernamentales frente a las semillas genéticamente modificadas en Colombia

Los efectos ambientales, económicos, sociales y culturales generados por las Semillas Genéticamente Modificadas-SGM y su control por empresas transnacionales como Monsanto, han incentivado la acción colectiva liderada por ONGs, tanto internacionalmente como en Colombia. El objetivo principal es analizar cómo la ONG “Semillas” ha incidido en las políticas colombianas relacionadas con la introducción y uso de SGM durante el periodo 2002-2013. Se centra en la Teoría de Redes Transnacionales de Defensa expuesta por M. Keck y K. Sikkink (1998). Además, se analiza el papel de las ONGs ambientales y las corporaciones transnacionales. El argumento central es que al crear vínculos con actores nacionales e internacionales y vincularse con redes y campañas con impacto transnacional, “Semillas” ha posicionado la lucha en contra de las SGM y ha logrado presionar al Estado influyendo parcialmente en sus políticas y leyes, al igual que en su posición y discurso frente al uso de SGM.

Análisis de las tendencias del sector de artes gráficas colombiano para el diseño de un plan estratégico de la empresa Editorial Edeco Ltda.

El presente texto expone el análisis del sector de artes gráficas, un sector que continúa en crecimiento y trae consigo nuevas tendencias y retos para las empresas, como por ejemplo la digitalización de contenidos, impresión por demanda, conciencia medioambiental, entre otros. Adicionalmente se expone las diferentes oportunidades y amenazas del sector, la competencia como una variable que afecta directamente la rentabilidad; debido a la guerra de precios existente y la Comoditización de productos y servicios. En el marco teórico se estudian herramientas como DOFA, matriz de Ansoff, benchmarking y primordialmente el análisis estructural de sectores estratégicos, que permite construir una percepción amplia de lo que ocurre en el sector, de tal forma que la empresa pueda replantear su modelo de negocio y pueda construir valor. Se realizaran propuestas de estrategias a desarrollar, con el fin de visualizar nuevos modelos de negocio que en el largo plazo garanticen la supervivencia del negocio, desde un enfoque de adaptación a las nuevas tendencias; así mismo se busca estudiar la posibilidad de entrar en el mundo de la digitalización de contenidos y la creación de nuevos productos que atiendan a los mismos segmentos de clientes actuales de una forma diferente.

Cuando creces, yo crezco contigo”: La configuración de áreas de protección ambiental y de subjetividades en el Humedal de Córdoba y la vereda El Verjón Bajo

La configuración de lugares como áreas de protección ambiental puede ser vista como un proceso técnico y objetivo, en el que se crean políticas públicas que definen prácticas adecuadas e inadecuadas en el lugar. Pero esta configuración es un proceso histórico y negociado. Este se construye en contante diálogo entre diferentes actores que se preocupan por definir qué es la naturaleza y el cuidado ambiental, y las percepciones que individuos que habitan en o cerca a estos lugares construyen en su diario vivir. Es así como la configuración socioambiental de lugares como áreas de protección ocurre por transformaciones en la forma de percibir un lugar, la relaciones con este y sobre todo, prácticas y relaciones que se traducen en formas de negociar nociones de naturaleza y cuidado ambiental. Esta negociación tiene grandes implicaciones en los individuos, particularmente en su subjetividad. Es decir, en hechos como la forma de nombrarlo, caminarlo, observar las especies, iniciar proyectos de agricultura orgánica, cambiar prácticas productivas, el cerramiento de zonas para proteger las fuentes de agua o zonas de vegetación. También sobre su subjetividad, la manera como se sienten frente al lugar, como juzgan sus acciones y las de otros y cómo construyen objetivos personales con respecto a la idea de cuidado ambiental.

Health Benefits of Organic Food: effects of the environment

Public concern over impacts of chemicals in plant and animal production on health and the environment has led to increased demand for organic produce, which is usually promoted and often perceived as containing fewer contaminants, more nutrients, and being positive for the environment. These benefits are difficult to quantify, and potential environmental impacts on such benefits have not been widely studied. This book addresses these key points, examining factors such as the role of certain nutrients in prevention and promotion of chronic disease, potential health benefits of bioactive compounds in plants, the prevalence of food-borne pesticides and pathogens and how both local and global environmental factors may affect any differences between organic and conventionally produced food. This book is an essential resource for researchers and students in human health and nutrition, environmental science, agriculture and organic farming. Main Contents 1. Organic farming and food systems: definitions and key characteristics. 2. The health benefits of n-3 fatty acids and their concentrations in organic and conventional animal-derived foods. 3. Environmental impacts on n-3 content of foods from ruminant animals. 4. Health benefits and selenium content of organic vs conventional foods. 5. Environmental impacts concerning the selenium content of foods. 6. Contaminants in organic and conventional food: the missing link between contaminant levels and health effects. 7. Mycotoxins in organic and conventional foods and effects of the environment. 8. Human pathogens in organic and conventional foods and effects of the environment. 9.

Post-Sustainable Development

The past 15 years have witnessed the rise of post-development theory as a means of understanding the development discourse since the 1940s. Post-development argues that intentional development (as distinct from immanent development - what people are doing anyway) is a construct of Western hegemony. Sustainable development, they argue, is no different and indeed is perhaps worse, given that most of the global environmental degradation has been driven by consumerism and industrialization in the West. Critics of post-development counter by stating that it only provides destruction by tearing apart what is currently practiced in 'development' without providing an alternative. When post-developmentalists do offer an alternative it typically amouints to little more than a call for more grassroots involvement in development and disengagement from a Western agenda. Post-sustainable development analysis and counter-analysis has received remarkably little attention within the sustainable development literature, yet this paper argues that it can make a positive contributrion by calling for an analysis of discourse rather than a hiding of power differentials and an assumption that consensus must exist within a community. A case is made for a post-sustainable development that acknowledges that diversity will exist and consensus may not be achievable, but at the same time participation can help with learning. The role of the expert within sustainable development is also discussed. Copyright (C) 2008 John Wiley & Sons, Ltd and ERP Environment.

Post-(sustainable)-development?

This paper critically reviews the application of a post-development analysis to sustainable development by employing a defined target for post-development analysis – the Environmental Kuznets Curve (EKC). Data from the 2005 Environmental Sustainability Index (ESI) for 146 countries are used to generate statistically significant EKC models, and the approach is deconstructed by employing post-development theory. While an ESI derived EKC is an easy target for post-development critique, there are foundations upon which both rest, and are not easily dismissed. Neither is the typical post-development 'alternative' of encouraging 'endogenous discourse' and grassroots movements at odds with sustainable development. As a result, this paper argues that sustainable development theory already incorporates much of the critique and alternatives raised by post-developmentalists. Indeed, what is more disconcerting is that sustainable development readily encompasses such apparently divergent ideas represented by the ESI, EKC and post-developmental critique and solutions.
