Estrategias de desarrollo sostenible de la arquitectura del oasis de M’hamid, desierto del Sahara

Esta investigación se plantea con la hipótesis radical de cómo habitar el desierto de forma sostenible, desde una actitud pragmática y experimental basada en el progreso. La justificación se basa en primer lugar en los 2.000 millones de personas en el mundo que viven en entornos desérticos, el 80% de ellas, en países en desarrollo, porque el 40% de la superficie terrestre está bajo amenaza de desertificación afectando al 37% de la población mundial, con 12 millones de hectáreas al año perdidas por esa causa, y por último, porque se considera el desierto como un entorno de gran atractivo y potencial. El contenido de la investigación se estructura en tres movimientos: posicionamiento, mirada y acción: Desde el posicionamiento se define en primer lugar la sostenibilidad, aportando un nuevo diagrama donde se incorpora el ámbito arquitectónico como uno de los pilares principales, y, posteriormente, se establecen los criterios de evaluación de la sostenibilidad, aportando un sistema de indicadores donde se incorporan parámetros adecuados a las circunstancias del oasis. Del mismo modo, se estudian y analizan metodologías de actuación y proyectos de desarrollo sostenible existentes que enmarcan el estado del arte, constatando la dificultad de adaptación de los mismos a las condiciones de los oasis, por lo que se elabora una metodología propia donde se modifica la dinámica estratégica, de forma que el impulso se plantea desde la acción social, a través de hipótesis de estrategias basadas en sistemas low-cost, autoconstruidas, asumibles económicamente y de implantación factible. El caso de estudio específico radica en la situación extrema de las condiciones en el oasis de M’hamid, donde se evidencia un proceso de desintegración y abandono. Esto es debido a una acumulación de circunstancias externas e internas, de múltiples factores: naturales y antrópicos que afectan al oasis, llevando al extremo las condiciones climáticas y la escasez de recursos, naturales y artificiales. Factores como el cambio climático, la sequía, los cambios en las políticas del agua, la amenaza de desertificación, los conflictos sociales, el desequilibrio ecológico, la escasez económica, la crisis energética, la obsolescencia arquitectónica, el patrimonio construido prácticamente destruido, y la malentendida nueva arquitectura. Es importante constatar la escasa documentación gráfica existente sobre la zona de actuación lo que ha conllevado un amplio trabajo de documentación, tanto cartográfica como de observación directa, aportada a la tesis como investigación de elaboración propia. La mirada analítica al caso de estudio permite conocer los recursos disponibles y las potencialidades latentes del oasis de M’hamid, que permitirán actuar para subvertir la dinámica involutiva imperante, de forma que los dibujos iniciales de apropiación contextual y análisis críticos derivan en mapas de acción diagramados conformados por un sistema de objetos y la definición de estrategias transversales, deconstruyendo el pasado y reconstruyendo el futuro, incorporando sistemas alternativos que se definen en 7 líneas estratégicas de acción formuladas desde los 3 ámbitos relacionados con el ecosistema: ecológico, socio- económico y arquitectónico. Así, la tesis defiende la acción arquitectónica como impulsora del desarrollo sostenible, apoyada en 3 elementos: - la creación de objetos “tecnoartesanos”, para el aprovechamiento de los recursos energéticos - las transformaciones arquitectónicas, para reformular el hábitat desde la eficiencia energética y el progreso - y el impulso de acciones cotidianas, que redefinan las relaciones sociales, creando entornos cooperativos y colaborativos. En el ámbito ecológico se proponen actuaciones anti desertificación mediante incubadoras de árboles; sistemas alternativos de gestión del agua, como la lluvia sólida; estrategias de potenciación de la producción agrícola; la construcción de mecanismos de obtención de energía a partir de residuos, como los paneles solares con botellas PET. En el ámbito socioeconómico se plantean nuevas formas de acción social y de reactivación económica. Por último, en el ámbito urbano-arquitectónico, se incorporan modificaciones morfológicas a la arquitectura existente y una relectura contemporánea de la tierra, como material que permite nuevas geometrías, obteniendo arena petrificada por procesos microbiológicos, y potenciando la tierra como recurso artístico. Esta tesis es un punto de partida, recoge sistemas, estrategias y experiencias, para funcionar como un estímulo o impulso dinamizador del futuro desarrollo sostenible del oasis, abriendo vías de investigación y experimentación. ABSTRACT This research puts forth the radical hypothesis of how to inhabit the desert in a sustainable way, using a pragmatic and experimental approach based on progress. The justification for this resides in the fact that there are 2,000 million people in the world living in desert environments, 80% of them in developing countries. Forty percent of the earth’s surface is under threat of desertification, affecting 37% of the world population and with 12 million hectares being lost each year. And finally, the desert is considered as an attractive environment and therefore, with great potential. The content of the research is structured in three main sections: positioning, observation and action: As a point of departure, sustainability is defined, proposing a new framework where architecture is incorporated as one of the main pillars. Then, the criteria for evaluating sustainability are established. These provide a system of indicators, which incorporate parameters based on the specific circumstances of the oasis. Methodologies and existing sustainable development projects that represent the state-of-the-art are analyzed, discussing the difficulty of adapting them to conditions of oases. A methodology that modifies strategic concepts is developed, whereby the catalyst is social action, and strategies are developed based on low-cost, self-built, and feasible implementation systems. The specific case study lies in the extreme conditions in the oasis of M'hamid, where a process of decay and neglect is evident. This deterioration is due to an accumulation of external and internal circumstances, and of natural and anthropogenic factors that affect the oasis, leading to extreme weather conditions and a shortage of both natural and artificial resources. Factors include; climate change, drought, changes in water policies, the threat of desertification, social conflicts, ecological imbalance, economic shortage, the energy crisis, architectural obsolescence, destruction of built heritage, and misunderstood new architecture. It is important to note the extremely limited graphic information about the area has led me to produce an extensive archive of maps and drawings, many developed by direct observation, that contribute to the research. The case study analysis of the oasis of M'hamid examines the resources available and the latent potential to slow the prevailing trend towards deterioration. The initial drawings of contextual appropriation and critical analysis result in maps and diagrams of action, which are formed by a system of objects and the definition of strategies. These can be thought of as understanding or “deconstructing” the past to reconstruct the future. Alternative approaches defined in seven strategies for action are based on three fields related to the ecosystem: ecological, socioeconomic and architectural. Thus, the thesis defends architectural action to promote sustainable development, based on three elements: - The creation of "techno-artisans", to make use of energy resources - Architectural changes, to reformulate habitat in terms of energy efficiency and progress - And the promotion of everyday actions, to redefine social relations, creating cooperative and collaborative environments. In the ecological field, I propose anti-desertification actions such as; tree incubators, alternative water management systems(such as solid rain),; strategies to empower the agricultural production, energy from low-cost systems made out from recycled materials(such as solar panels from PET bottles or wind turbine from bicycle wheels). In the socioeconomic sphere, I propose to implement new forms of social action and economic regeneration. Finally, within the urban and architectural field, I propose morphological changes to the existing architecture and a contemporary reinterpretation of the earth as a material that allows new geometries, creating petrified sand by microbiological processes or enhancing nature as an artistic and energy resource. This thesis is a starting point. It collects systems, strategies and experiences to serve as a stimulus or dynamic momentum for future sustainable development of the oasis, opening new avenues of research and experimentation. RÉSUMÉ Cette recherche part d'une hypothèse radicale : comment habiter le désert de façon durable, et ce à partir d'une approche pragmatique et expérimentale basée sur le progrès. Cette hypothèse se justifie en raison des 2 milliards de personnes qui dans le monde habitent des environnements désertiques, 80% d'entre eux dans des pays en voie de développement, mais aussi parce que 40% de la surface de la planète est sous menace de désertification, un phénomène affectant 37% de la population mondiale et qui cause la perte de 12 millions d'hectares par an; et enfin parce que le désert est considéré comme un environnement très attrayant et fort d’un grand potentiel. Le contenu de la recherche se divise en trois mouvements: le positionnement, le regard et l'action : Du point de vue du positionnement on définit tout d'abord la durabilité, présentant un nouveau schéma où le domaine de l'architecture devient un des principaux piliers, et, par la suite, des critères d'évaluation de la durabilité sont établis, en fournissant un système d’indicateurs qui intègre les paramètres appropriés aux circonstances de l'oasis. De même, des méthodologies et des projets de développement durable existants sont étudiés et analysés, ce qui encadre l'état de l'art, remarquant la difficulté de les adapter aux conditions des oasis. De cette difficulté découle l'élaboration d'une méthodologie qui modifie la dynamique stratégique, de sorte que l'impulsion provient de l'action sociale, à travers des hypothèses de stratégie basées sur des systèmes low-cost, auto-construits, et de mise en oeuvre économiquement viable. Le cas d'étude spécifique réside en la situation extrême des conditions de l'oasis de M’hamid, où un processus de décadence et de négligence est évident. Cela est dû à une accumulation de circonstances externes et internes, de multiples facteurs: les facteurs naturels et anthropiques qui affectent l'oasis, menant à l'extrême les conditions météorologiques et la pénurie de ressources, autant naturelles qu'artificielles. Des facteurs tels que le changement climatique, la sécheresse, les changements dans les politiques de l'eau, la menace de la désertification, les conflits sociaux, le déséquilibre écologique, la pénurie économique, la crise de l'énergie, l'obsolescence architecturale, le patrimoine bâti pratiquement détruit et une mauvais compréhensif de la nouvelle architecture. Il est important de de faire remarquer le peu d'informations graphiques du domaine d'action, ce qui a conduit à un vaste travail de documentation, autant cartographique que relative à l'observation directe. Cette documentation s'ajoute à la thèse en tant que recherche propre. Le regard analytique sur le cas d'étude permet de connaître les ressources disponibles et le potentiel latent de l'oasis de M’hamid, qui agiront pour renverser la dynamique d'involution en vigueur. Ainsi, les premiers dessins d'appropriation contextuelle et analyse critique deviennent des cartes d'action schématisées formées par un système d'objets et la définition de stratégies transversales, qui déconstruisent le passé et reconstruisent l'avenir, en incorporant des systèmes alternatifs qui se définissent sur 7 lignes stratégiques d'action formulées à partir des 3 domaines en relation avec l’écosystème: l’écologique, le socio-économique et l'architectural. Ainsi, la thèse défend l'action architecturale en tant que promotrice du développement durable, et ce basé sur 3 éléments: - la création d'objets "technoartisans" pour l'exploitation des ressources énergétiques - les modifications architecturales, pour reformuler l'habitat du point de vue de l'efficacité énergétique et le progrès - et la promotion des actions quotidiennes, pour redéfinir les relations sociales, et la création d'environnements de coopération et collaboration. Dans le domaine de l'écologie des actions de lutte contre la désertification sont proposées à travers des pépinières d'arbres, des systèmes alternatifs de gestion de l'eau comme par exemple la pluie solide, des stratégies de mise en valeur de la production agricole, la construction de mécanismes de production d'énergie à partir de résidus, tels que les panneaux solaires ou les bouteilles en PET. Dans le domaine socio-économique, l'on propose de nouvelles formes d'action sociale et de reprise économique. Enfin, dans le domaine de l'urbain et de l'architectural, on incorpore des changements morphologiques à l'architecture existante et une relecture contemporaine de la terre, comme matériau qui permet de nouvelles géométries, en obtenant du sable pétrifié par des procédés microbiologiques et en mettant en valeur la terre comme une ressource artistique. Cette thèse n'est qu'un point de départ. Elle recueille des systèmes, des stratégies et des expériences pour servir de stimulus ou d'impulsion dynamisatrice du futur développement durable de l'oasis, en ouvrant des voies de recherche et d'expérimentation.

Policy processes and collective action in water reforms: the cases of Nicaragua and Suriname

Las reformas de agua en países en desarrollo suelen llevarse a cabo junto con cambios institucionales más profundos o, incluso, acompañadas de cambios constitucionales o de régimen político. Por lo tanto, los marcos institucionales adaptados a países gobernados sujetos al estado de derecho pueden no ser apropiados para contextos gobernados fundamentalmente, al menos en sus inicios, por instituciones informales o poco maduras. Esta tesis toma las reformas de agua como punto de partida y pretende contribuir a la literatura mediante una serie de análisis empíricos tanto del ámbito general como del plano individual o sujeto personal de la política del agua. En el ámbito general, el foco se pone en los factores que explican el fallo de la acción colectiva en dos contextos diferentes: 1) en la implementación de la nueva Ley de Aguas de Nicaragua y 2) en el mantenimiento y revitalización de las instituciones de riego en Surinam. En el plano del individuo, la investigación se centra en las decisiones de los usuarios de los recursos y analiza el papel crítico de las variables sociales para la gestión de los recursos comunes. Para ello, el método de investigación utilizado es mixto, combinando el análisis de entrevistas, encuestas y experimentos. En el ámbito general, los resultados muestran que las principales barreras para la implementación de la nueva Ley de Aguas de Nicaragua podrían tener su reflejo en el lenguaje de la Ley y, por tanto, en la forma en la que se definen y configuran las instituciones incluidas en dicha Ley. Así, la investigación demuestra que la implementación de políticas no puede ser estudiada o entendida sin tener en cuenta tanto el diseño de la propia política como el marco socio-ecológico en el que se enmarca. El contexto específico de Nicaragua remarca la importancia de considerar tanto las instituciones formales como informales en los procesos de transición política. A pesar de que las reformas de agua requieren plazos largos para su implementación, el hecho de que exista una diferencia entre las reglas tal cual se definen formalmente y las reglas que operan en la realidad merece una mayor consideración en el diseño de políticas basadas fundamentalmente en instituciones formales. En el ámbito de la conducta individual, el análisis de la acción colectiva ofrece una serie de observaciones empíricas interesantes. En el caso de Nicaragua, los resultados indican que la intensidad de las relaciones sociales, el tipo de agentes dispuestos a proporcionar apoyo social y el nivel de confianza en la comunidad son factores que explican de manera significativa la participación en la comunidad. Sin embargo, el hecho de que la gestión colectiva de riego se produzca, en la mayoría de casos, en torno a lazos familiares sugiere que las variables de capital social críticas se definen en gran medida en la esfera familiar, siendo difícil que se extiendan fuera de estos nexos. El análisis experimental de los resultados de un juego de uso de recurso común y contribución al bien público muestra que las preferencias pro-sociales de los individuos y la heterogeneidad del grupo en términos de composición por sexo son factores que explican significativamente los resultados y las decisiones de apropiación a lo largo del juego. En términos del diseño de las políticas, es fundamental tener en cuenta las dinámicas de participación y uso de los recursos comunes de manera que los niveles de cooperación puedan mantenerse en el largo plazo, lo cual, como se observa en el caso de Surinam, no es siempre posible. Finalmente, el caso de Surinam es un ejemplo ilustrativo de los procesos de acción colectiva en economías en transición. El análisis del fallo de la acción colectiva en Surinam muestra que los procesos políticos vinculados al período colonial y de independencia explican en gran medida la falta de claridad en las reglas operacionales y colectivas que gobiernan la gestión de los sistemas de riego y drenaje. Los resultados empíricos sugieren que a pesar de que la acción colectiva para la provisión de los servicios de riego y drenaje estaba bien establecida bajo el régimen colonial, la auto-organización no prosperó en un contexto dependiente del apoyo externo y regido fundamentalmente por reglas diseñadas al nivel competencial del gobierno central. El sistema socio-ecológico que se desarrolló durante la transición post-colonial favoreció, así, la emergencia de comportamientos oportunistas, y posteriormente la inoperancia de los Water Boards (WBs) creados en la época colonial. En este sentido, cualquier intento por revitalizar los WBs y fomentar el desarrollo de la auto-organización de los usuarios necesitará abordar los problemas relacionados con los patrones demográficos, incluyendo la distribución de la tierra, el diseño de instituciones y la falta de confianza en el gobierno, además de las inversiones típicas en infraestructura y sistemas de información hidrológicos. El liderazgo del gobierno, aportando empuje de arriba-abajo, es, además, otro elemento imprescindible en Surinam. ABSTRACT Water reforms in developing countries take place along deeper institutional and even constitutional. Therefore, institutional frameworks that might result in positive outcomes in countries governed by the rule of law might not fit in contexts governed mainly by informal or immature institutions. This thesis takes water reforms as the starting point and aims to contribute to the literature by presenting several conceptual and empirical analyses at both general and individual levels. At the general national level, the focus is on the factors explaining failure of collective action in two different settings: 1) in the implementation of the new Nicaraguan Water Law and 2) in sustaining and revitalizing irrigation institutions in Suriname. At the individual level, the research focuses on the actions of resource users and analyzes the critical role of social variables for common pool resources management. For this purpose, the research presented in this thesis makes use of a mixed-method approach, combining interviews, surveys and experimental methods. Overall, the results show that major barriers for the implementation of the new Nicaraguan Water Law have its reflection on the language of the Law and, therefore, on the way institutions are defined and configured. In this sense, our study shows that implementation cannot fruitfully be studied and understood without taking into account both the policy design and the social-ecological context in which it is framed. The specific setting of Nicaragua highlights the relevance of considering both formal and informal institutions when promoting policy transitions. Despite the unquestionable fact that water reforms implementation needs long periods of time, there is still a gap between the rules on paper and the rules on the ground that deserves further attention when proposing policy changes on the basis of formal institutions. At the level of the individual agent, the analysis of collective action provides a number of interesting empirical insights. In the case of Nicaragua, I found that the intensity of social networks, the type of agents willing to provide social support and the level of trust in the community are all significant factors in explaining collective action at community level. However, the fact that most collective irrigation relies on family ties suggests that critical social capital variables might be defined within the family sphere and making it difficult to go beyond it. Experimental research combining a common pool resource and a public good game in Nicaragua shows that individuals’ pro-social traits and group heterogeneity in terms of sex composition are significant variables in explaining efficiency outcomes and effort decisions along the game. Thus, with regard to policy design, it is fundamental to consider carefully the dynamics of agents' participation and use of common pool resources, for sustaining cooperation in the long term, which, as seen in the case and Surinam, is not always possible. The case of Suriname provides a rich setting for the analysis of collective action in transition economies. The analysis of decay of collective irrigation in Suriname shows that the lack of clear operational and collective choice rules appear to be rooted in deeper political processes that date back to the colonial period. The empirical findings suggest that despite collective action for the provision of irrigation and drainage services was well established during the colonial period, self-organization did not flourish in a context governed by colonial state-crafted rules and mostly dependent on external support. The social-ecological system developed during the post-colonial transition process favored the emergence of opportunistic behavior. In this respect, any attempt to revitalize WBs and support self-organization will need to tackle the problems derived from demographic patterns, including land allocation, institutions design and government distrust, in addition to the typical investments in both physical infrastructure and hydrological information systems. The leadership role of the government, acting as a top-down trigger, is another essential element in Suriname.

Impact of new technologies and social networks on a secondary education theatre project

This paper describes the potential impact of social media and new technologies in secondary education. The case of study has been designed for the drama and theatre subject. A wide set of tools like social networks, blogs, internet, multimedia content, local press and other promotional tools are promoted to increase students’ motivation. The experiment was developed at the highschool IES Al-Satt located in Algete in the Comunidad de Madrid. The students included in the theatre group present a low academic level, 80% of them had previously repeated at least one grade, half of them come from programs for students with learning difficulties and were at risk of social exclusion. This action is supported by higher and secondary education professors and teachers who look forward to implanting networked media technologies as new tools to improve the academic results and the degree of involvement of students. The results of the experiment have been excellent, based on satisfactory opinions obtained from a survey answered by students at the end of the course, and also revealed by the analytics taken from different social networks. This project is a pioneer in the introduction and usage of new technologies in secondary high-schools in Spain.

The Role of ICT in Scaling Up the Impact of Social Enterprises

Information and Communication Technologies (ICT) can help social enterprises and other organizations working on global sustainability issues and in the human development sector in general scale their social impact. The flexibility, dynamism, and ubiquity of ICTs make them powerful tools for improving relationships among organizations and their beneficiaries, multiplying the effects of action against many, if not all, aspects of global unsustainability, including poverty and exclusion. The scaling of social impact occurs in two different dimensions. On one hand, ICTs can increase the value proposition of a program or action (depth scaling) in different ways: providing accurate and fast needs recognition, adapting products and services, creating opportunities, building fairer markets, mobilizing actions on environmental and social issues, and creating social capital. On the other hand, ICTs can also increase the number of people reached by the organization (breadth scaling) by accessing new resources, creating synergies and networks, improving organizational efficiency, increasing its visibility, and designing new access channels to beneficiaries. This article analyzes the role of ICT in the depth and breadth scaling of social impact.

COST Action Urban Agriculture Europe Training School «Urban agriculture inside the city:alternatives for vacant lots and public space»

The third Training School of the Action took place in Vitoria-Gasteiz (Basque country, Spain) from 24th to 26th September 2014. Vitoria-Gateiz has experimented an important urban outgrowth in the last decade, mainly through the planning and development of two new neighborhoods, Zabalgana and Salburúa, situated at the eastern and western border of the city, by the Greenbelt. These new development are well-equipped and designed according to sustainability principles. Nevertheless, among the main problems they present is their over-dimensioned public space, which creates some areas lacking enough density and mix of uses. On the other hand it is very expensive for the municipality to maintain these public space with the high Vitorian urban standards for public space. The proposed solution for this problem is a strategy of "re-densification" through the insertion of new uses The debate has arisen about which are the most adequate uses to insert in order to get an increasing of urban vitality, specially considering that housing has reached its peak and that Vitoria-Gasteiz is well served with social and sport amenities. The main goal of the TS was to offer an opportunity for the reflection about how urban agriculture might be an optimal alternative for the re-qualifying of this over-dimensioned public space in the new neighbourhoods, especially considering it synergic potential as a tool for production, leisure and landscaping, including the possibility of energy crops within the limits of urban space. Continuity with rural and natural surrounding area through alternatives for urban fringe at the small scale is a relevant issue to be considered as well within the reflection. Taking Zabalgana neighbourhood as a practical field for experiment, the Training School is conceived as a practical and intensive design charrette to be held during a whole day after two days of local knowledge-deepening through field visits and presentations.

Fashion in Actions on Social Media – Spanish SME Fashion Brands Case Studies

Fashion is one of the most vibrant sectors in Europe and important contributors to the European Union (EU) economy. In particular, Small and Medium Enterprises (SMEs) play a major part in European fashion industry (EU 2012). Just like fashion, where people¿s style has inherently meant to be shared as it is foremost a representation of one¿s self-image, social media allow the reflection of ones' personality and emotions. Although fashion practitioners have embraced social media in their marketing activities, it is still relatively few known at an academic level about the specificities of fashion industry when approaching social media marketing (SMM) strategies. This study sets out to explore fashion companies' SMM strategy and its activities. From an exploratory approach, we present case studies of two Spanish SME fashion companies, anonymously named hereafter as Company A and Company B, to deepen our understanding on how fashion brands implement their SMM strategy. Company A offers high-end fashion products while Company B produces medium fashion products. We analyzed the case studies using qualitative (interviews to companies' executives) and a mix of qualitative and quantitative (content analysis of companies' social media platform) methods. Public posts data of both companies' Facebook brand pages were used to perform the content analysis. Our findings through case studies of the two companies reveal that branding-oriented strategic objectives are the main drivers of their SMM implementations. There are significant differences between both companies. The main strategic action employed by Company A is engaging customers to participate into brand's offline social gathering events by inviting them through social media platform, while Company B focuses its effort on posting product promotion related contents and engaging influencers such as fashion bloggers. Our results are expected to serve as a basis of further investigations on how SMM strategy and strategic actions implemented by fashion brands may influence marketing outcomes.

Knowledge-action integration through the media in indigenous communities in Ecuador

The binomial knowledge/action understood under the biunivocal relationship of both components is the basis of planning from a postmodern approach. Within this binomial, social communication gives appropriate information, nurtures the knowledge that leads to transformative action, promotes participation and enhances the community?s self-esteem and recognition; to deeply reflect on action is a source of new knowledge; and communication fosters the adoption of the new knowledge by the community with new actions that feed the process knowledge/action as a planning source. From this approach the project Radio Message is born as a new communication channel with the aim of offering Andean indigenous communities from the area of Cayambe (Ecuador), a series of multidisciplinary training programs that enable transformative action with a strong effect on the life quality in these communities and their importance as social actors. The contents are designed through participatory communication between the training authorities and the communities themselves, analyzing their opportunities and needs. In this research the impact of social media in the development of more than 100 indigenous communities in Cayambe is analyzed.
