Desafíos complejos como el desarrollo rural sustentable requieren de la integración de las ciencias sociales y ecológicas, y de un papel activo de las ciencias agropecuarias como interfaz conceptual y metodológica. El objetivo general de la tesis es estudiar la vulnerabilidad y robustez de los sistemas trashumantes en el norte de Neuquén, Argentina, analizando la heterogeneidad de componentes y procesos socio-ecológicos y su relación con factores de disturbio o cambios de contexto, considerando las percepciones de diferentes actores sociales. El estudio incorpora una perspectiva del uso del paisaje basado en el análisis de las redes de movimientos de trashumancia y conectividad entre ambientes a escala regional, en tanto constituye una adaptación a la heterogeneidad espacial y temporal biofísica. Se evaluaron las implicancias de los cambios en la organización y dinámicas sociales promovidos por la urbanización. A su vez, se abordaron las perspectivas sobre amenazas, problemas y oportunidades mediante estudios de las percepciones de los agentes de intervención y los crianceros. La vulnerabilidad y la robustez socio-ecológica en sistemas trashumantes varían espacial y temporalmente, y estuvieron influenciadas por un componente de subjetividad, que dependió del sujeto social indagado. La robustez del sistema trashumante depende de la movilidad como estrategia socio-productiva, y de la flexibilidad y capacidad de adaptación ya no sólo frente a la heterogeneidad biofísica, sino también a cambios de origen social. La dependencia de las redes trashumantes respecto de ciertas zonas o nodos clave y de los servicios ecológicos como principal medio de vida, sugieren una mayor sensibilidad a cambios que afecten dichos nodos. Uno de los principales desafíos a futuro es la construcción de una gobernanza activa y plural y una mayor articulación urbano-rural. Se requieren instituciones flexibles y la gobernanza debiera adaptarse a la dinámica socio-productiva regional, con participación de diferentes actores sociales y perspectivas de acción.

Natural gas, especially unconventional gas, has an increasingly important role in meeting the world's energy needs. Experts estimate that it has the potential to add anywhere from 60-250% to the global proven gas reserve in the next two decades. To maintain pace with increasing global demand, Unconventional Gas Reservoirs provides the necessary bridge into the newer processes, approaches and designs to help identify these more uncommon reservoirs available and how to maximize its unconventional potential.

Loaded with reservoir development and characterization strategies, this book will show you how to:

• Recognize the challenges and opportunities surrounding unconventional gas reservoirs
• Distinguish among the various types of unconventional reservoirs, such as shale gas, coalbed methane, and tight gas formations
• Drill down and quantify the reservoir’s economic potential and other critical considerations

• Gain practical insights and tools to efficiently identify, appraise, and develop unconventional gas reservoirs
• Understand various techniques used to analyze reservoir parameters and performance as well as how they were applied to numerous real-world case studies
• Upgrade to the latest information on perspectives and insights with discussion of key differences used for today’s unconventional gas characterization versus original conventional methods that failed in the past

Unconventional Oil and Gas Resources Handbook: Evaluation and Development is a must-have, helpful handbook that brings a wealth of information to engineers and geoscientists. Bridging between subsurface and production, the handbook provides engineers and geoscientists with effective methodology to better define resources and reservoirs. Better reservoir knowledge and innovative technologies are making unconventional resources economically possible, and multidisciplinary approaches in evaluating these resources are critical to successful development. Unconventional Oil and Gas Resources Handbook takes this approach, covering a wide range of topics for developing these resources including exploration, evaluation, drilling, completion, and production. Topics include theory, methodology, and case histories and will help to improve the understanding,integrated evaluation, and effective development of unconventional resources.

• Presents methods for a full development cycle of unconventional resources, from exploration through production
• Explores multidisciplinary integrations for evaluation and development of unconventional resources and covers a broad range of reservoir characterization methods and development scenarios
• Delivers balanced information with multiple contributors from both academia and industry
• Provides case histories involving geological analysis, geomechanical analysis, reservoir modeling, hydraulic fracturing treatment, microseismic monitoring, well performance and refracturing for development of unconventional reservoirs

Understanding Atrocities is a wide-ranging collection of essays bridging scholarly and community-based efforts to understand and respond to the global, transhistorical problem of genocide. The essays in this volume investigate how evolving, contemporary views on mass atrocity frame and complicate the possibilities for the understanding and prevention of genocide. The contributors ask, among other things, what are the limits of the law, of history, of literature, and of education in understanding and representing genocidal violence? What are the challenges we face in teaching and learning about extreme events such as these, and how does the language we use contribute to or impair what can be taught and learned about genocide? Who gets to decide if it's genocide and who its victims are? And how does the demonization of perpetrators of atrocity prevent us from confronting the complicity of others, or of ourselves? Through a multi-focused and multidisciplinary investigation of these questions, Understanding Atrocities demonstrates the vibrancy and breadth of the contemporary state of genocide studies.

Urban Ecosystems is an international journal devoted to scientific investigation of the ecology of urban environments, and policy implications. The scope is broad, including interactions between urban ecosystems and associated suburban and rural environments. The ecology of urban forests receives special emphasis. Contributions span a range of specific subject areas related to urban environments: biodiversity, biogeochemistry, conservation, ecosystem ecology, environmental chemistry, hydrology, landscape architecture, meteorology and climate, policy, population biology, social and human ecology, soil science, urban planning and wildlife and fisheries management.
