Quasi-experimental evidence on the drivers of index-based livestock insurance demand in Southern Ethiopia

Microinsurance is widely considered an important tool for sustainable poverty reduction, especially in the face of increasing climate risk. Although index-based microinsurance, which should be free from the classical incentive problems, has attracted considerable attention, uptake rates have generally been weak in low-income rural communities. We explore the purchase patterns of index-based livestock insurance in southern Ethiopia, focusing in particular on the role of accurate product comprehension and price, including the prospective impact of temporary discount coupons on subsequent period demand due to price anchoring effects. We find that randomly distributed learning kits contribute to improving subjects' knowledge of the products; however, we do not find strong evidence that the improved knowledge per se induces greater uptake. We also find that reduced price due to randomly distributed discount coupons has an immediate, positive impact on uptake, without dampening subsequent period demand due to reference-dependence associated with price anchoring effects.

Supporting eradication of maternal child malnutrition in developing countries: a case from Nicaragua scenario.

World Health Organization actively stresses the importance of health, nutrition and well-being of the mother to foster children development. This issue is critical in the rural areas of developing countries where monitoring of health status of children is hardly performed since population suffers from a lack of access to health care. The aim of this research is to design, implement and deploy an e-health information and communication system to support health care in 26 rural communities of Cusmapa, Nicaragua. The final solution consists of an hybrid WiMAX/WiFi architecture that provides good quality communications through VoIP taking advantage of low cost WiFi mobile devices. Thus, a WiMAX base station was installed in the health center to provide a radio link with the rural health post "El Carrizo" sited 7,4 km. in line of sight. This service makes possible personal broadband voice and data communication facilities with the health center based on WiFi enabled devices such as laptops and cellular phones without communications cost. A free software PBX was installed at "San José de Cusmapa" health care site to enable communications for physicians, nurses and a technician through mobile telephones with IEEE 802.11 b/g protocol and SIP provided by the project. Additionally, the rural health post staff (midwives, brigade) received two mobile phones with these same features. In a complementary way, the deployed health information system is ready to analyze the distribution of maternal-child population at risk and the distribution of diseases on a geographical baseline. The system works with four information layers: fertile women, children, people with disabilities and diseases. Thus, authorized staff can obtain reports about prenatal monitoring tasks, status of the communities, malnutrition, and immunization control. Data need to be updated by health care staff in order to timely detect the source of problem to implement measures addressed to alleviate and improve health status population permanently. Ongoing research is focused on a mobile platform that collects and automatically updates in the information system, the height and weight of the children locally gathered in the remote communities. This research is being granted by the program Millennium Rural Communities of the Technical University of Madrid.

Dynamics in the governance of collective irrigation systems: Evidence from field experiments in Nicaragua.

The objective of this study is to analyze the common pool resource appropriation and public good provisiondecisions in a dynamic setting, testing the differences in behavior and performance between lab and field subjects. We performeda total of 45 games in Nicaragua, including 88 villagers in rural communities and 92 undergraduate students. In order to analyze sequential decision making, we introduce a dynamic and asymmetric irrigation game that combines the typical social dilemmas associated to irrigation systems management.In addition, in 9 out of 22 villagers’ groups, we implemented a treatment that included the disclosure of subjects’ appropriation of the common pool resource. The results reveal that the provision of individuals’ appropriation level results in higher appropriation in subsequent rounds. In addition, the results show that non-treated villagers provide more public good than treated villagers but if compared with students the differences are not significant. The results also suggest that appropriation levels are below the Nash prediction of full appropriation, but above the social efficient level. This results in an efficiency loss in the game that can be explained to a large extent by individual decisions on appropriation and public good contribution and by group appropriation behavior.

A telematics solution for the remote follow-up of malnourished children in underserved areas

The identification of malnourished children living under extreme poverty conditions in isolated areas is crucial to trigger urgent interventions like supplementary or therapeutic feeding. This work aims to strengthen the task of following-up malnourished maternal-child population in rural areas of developing countries like Nicaragua. The solution facilitates low-cost health nutritional remote monitoring to support rural communities at the point of care. Thus, the system allows medical staff to communicate with brigades, who transmit anthropometric measurements, such as weight and height of the children, from communities which are sited about 12 km. far away. A hybrid WiMAX/WiFi architecture was deployed to provide affordable communications between the isolated communities and the health center. Furthermore, a free PBX software and an open information system, installed at the health center, support WiFi based mobile communications and information management to support the care needs of maternal-child population at risk.

Cadena de valor de papas nativas (Solanum andigenum sp.) en la provincia de Jauja, Perú

La Asamblea General de la ONU, a solicitud del gobierno peruano, declara en el año 2008 el Año Internacional de la Papa, (AIP). Desde el año 2005, el gobierno peruano ha puesto en marcha estrategias en torno a la importancia de la papa, como la declaración del 30 de Mayo como el Día Nacional de la Papa. El año 2014 es declarado por la FAO, (Food and Agriculture Organization of the United Nations), Año Internacional de la Agricultura Familiar, con un enfoque compartido por esta Tesis Doctoral en el apoyo a la familia campesina peruana. El gobierno peruano utiliza las cadenas de valor como una estrategia de promoción de desarrollo sostenible, que ha permitido contribuir a la inclusión social y económica de productores pobres de zonas alto andinas, como las localizadas en la mancomunidad municipal del Yacus, (MMY), provincia de Jauja, departamento de Junín. Esta estrategia, en la que el mercado incorpora a los pequeños agricultores de las zonas altas de los Andes, (que disponen de recursos económicos muy bajos), en procesos productivos rentables, implica una serie de cambios a realizar, como la transformación de los patrones de producción tradicional hacia aquellos productos o servicios que tienen demanda en el mercado, o la variación de la mentalidad del agricultor pequeño hacia una concepción empresarial de su producción. (Fabián, 2013). Por otra parte, la sostenibilidad de las cadenas de valor depende del eslabón más débil, lo que obliga a conocer la situación de todos los eslabones para poder integrar y reforzar la cadena. Se requiere un sistema de transparencia adecuado que facilite el flujo de la información entre los distintos eslabones. (Briz et al., 2012). Además, el establecimiento de la cadena de valor debe hacerse con cuidado, ya que la eficacia y supervivencia de las empresas están cada vez más ligadas a la cadena de valor a la que pertenece y a la coordinación de la misma. (Briz, 2011). En esta situación, adquiere importancia el estudio de la cadena de valor de la papa nativa, para una vez establecidas sus características, poder determinar la viabilidad o no de una cadena de valor de este producto que repercuta parte de la riqueza generada en los pequeños agricultores alto andinos, e incluso, de su extensión hasta España. Existen estudios sobre las papas nativas, realizadas por diferentes universidades de distintos países, e incluso, de diferentes continentes. Sin embargo, la mayoría de los estudios se centran en la mejora de la producción de la papa nativa. La novedad de la investigación realizada en la presente Tesis Doctoral radica en el estudio de la viabilidad de la comercialización de la papa nativa, mediante el establecimiento de una cadena de valor que se inicie en la provincia de Jauja, Perú, y finalice tanto en los mercados peruanos de las regiones de Junín y Lima, como en España. El objetivo planteado en esta investigación es la mejora de las condiciones económicas y sociales de las comunidades agrícolas de la provincia de Jauja en el Perú, así como fomentar su desarrollo tecnológico e industrial, mediante el fomento de la cadena de valor de la papa nativa y sus derivados. Se establecen como objetivos específicos la caracterización de los eslabones de la cadena de valor de la papa nativa y sus derivados en la provincia de Jauja del Perú y en España, de manera que se determine el valor agregado en los mismos; el fortalecimiento de las organizaciones de productores de papas nativas para la comercialización de sus producciones y para el fomento de la cultura empresarial; y el desarrollo de una cadena de comercialización papas nativas y sus derivados con origen en la Provincia de Jauja, Perú, y que finalice en España, con la venta al consumidor español. Para alcanzar estos objetivos la metodología utilizada es la cadena de valor agroalimentaria, utilizando como herramientas de análisis el análisis DAFO de la cadena de valor de la papa nativa. Las fuentes de información primarias utilizadas proceden en parte del proyecto de cooperación de UPM, “Mejora de la cadena de valor de la patata andina como impulso al desarrollo rural. Caso de tres Comunidades Campesinas en la Provincia de Jauja del Perú”, en el que participó el doctorando, y en parte proceden de la batería de encuestas específicamente diseñadas para los diferentes eslabones de la cadena de valor de la papa nativa. Las fuentes de información secundarias proceden de artículos académicos publicados, de artículos publicados por revistas especializadas del sector y de informes realizados por diferentes instituciones gubernamentales, tanto españolas como peruanas. Las conclusiones de la investigación son las siguientes. La creación de la mancomunidad del Yacus ha beneficiado a los pequeños agricultores. Estos consiguen mejores condiciones de venta y mejores precios para sus productos, lo que repercute en la mejora de sus condiciones de vida. Estas mejoras en las condiciones de venta de los productos se deben a su pertenencia a una cadena de valor de papa nativa que está funcionando de forma eficaz. Las empresas consideradas para constituir la cadena de valor han mostrado interés por formar parte de ella: los campesinos para obtener mejores precios por sus productos y unas mejores condiciones de venta; los distribuidores para asegurarse una calidad determinada de unas variedades fijas de papa nativa; la industria transformadora por disponer de un suministro de producto adecuado al derivado de papa nativa correspondiente, (hojuelas, tunta, etc.); las empresas exportadoras para tener suministro garantizado de los productos que ellos requieren en los volúmenes adecuados. Es una situación ventajosa para todas las empresas participantes. A pesar de trabajar con un producto tradicional, la cadena de valor de la papa nativa presenta innovación en los productos comercializados, tanto en la papa nativa fresca como en sus derivados, en los formatos de los productos, en la red de distribución, en las instituciones peruanas y en el consumidor final. Se percibe una demanda de papa nativa y de sus productos derivados en aquellos países donde existen comunidades de latinoamericanos que han emigrado de sus países de origen. España está entre los países que han acogido a un importante número de personas de origen latinoamericano. A pesar de la fuerte crisis económica sufrida por España, que ha llevado consigo la vuelta a sus países de origen de parte de su comunidad latinoamericana, el tamaño de esta población sigue siendo importante. Esta población demanda productos originarios de sus propios países, y los consumirían de forma frecuente si los precios son adecuados a su capacidad de consumo. El precio de venta de la papa nativa y sus derivados en España es de gran importancia. La importación de estos productos desde Perú hace que este eleve a niveles que le resta competitividad, en especial en la papa fresca. Se aconseja la búsqueda de empresas que puedan adaptar la producción de la papa fresca de forma local, y mantener para los derivados la exportación directa a España. Las preferencias de los consumidores peruanos y españoles en cuanto a formatos y marcas se refieren no son coincidentes. De las encuestas realizadas, se concluye que no puede seguirse la misma estrategia de marketing en ambos países, debiéndose diferenciar los formatos de los paquetes de la papa nativa y de sus derivados en España y en Perú, para así lograr llegar a los consumidores potenciales de ambos países. ABSTRACT At the request of the Peruvian government, the UN General Assembly declared the International Year of the Potato in 2008. Since 2005, the Peruvian government has implemented strategies around the importance of the potato, as the declaration of the 30th of May as the National Day of the Potato. FAO (Food and Agriculture Organization of the United Nations) has declared 2014 as the International Year of Family Farming, with an approach shared by this Ph.D. dissertation about the Peruvian peasant family. The Peruvian government uses value chains as a strategy to promote sustainable development, which has allowed to contribute to the social and economic inclusion of poor farmers in the high Andean regions as those located in the municipal commonwealth of Yacus (MMY) province of Jauja, department of Junín. This strategy, which incorporates small farmers in the high Andean regions, (who have very low income), to the market with profitable production processes, implies a number of changes that should take place, such as changing patterns of traditional production to those products or services that are in demand in the market, or changes in the mentality of the small farmer into a concept of production business. (Fabián, 2013). Moreover, the sustainability of value chains depends on the weakest link, which demands a knowledge of the status of all the links, in order to integrate and strengthen the chain. It is required an adequate transparency to facilitate the flow of information between the various actors. (Briz et al., 2012). Furthermore, the establishment of the value chain should be done carefully, since the effectiveness and the survival of the businesses are increasingly linked to the value chain where the firm is included and to its coordination. (Briz, 2011). In this situation, it becomes important to study the value chain of the native potato, once we establish its features, to be able to determine the feasibility or not of a value chain of this product, which has an impact of the generated wealth in small farms of the high Andean regions, and even the extension of this value chain to Spain. There are studies on native potatoes, made by different universities in several countries and even in more than one continent. However, most studies focus on improving the production of native potato. The originality of the research conducted in this Ph.D. dissertation is the study of the feasibility of commercialization of native potato, by the creation of a value chain that starts in the province of Jauja, Perú, and ends both in Peruvian markets in the region of Lima, and in Spain. The main goal of this research is to improve the economic and social conditions of farming communities in the province of Jauja in Perú, while promoting its technological and industrial development, by the establishment of a value chain of the native potato and derivatives. The specific objectives of the research are the characterization of the links in the value chain of the native potato and its derivatives in the province of Jauja, (Perú) and in Spain, in order to determine the added value; the strengthening of organizations of native potato producers, to commercialize their products and the promotion of enterprise culture; and the development of a chain to market native potato and its derivatives, with its origin in the province of Jauja, (Perú), and its end in Spain, with the sale to the Spanish consumer. In order to achieve these objectives, the used methodology is the agrifood value chain, using as a tool to analysis it the SWOT analysis of the value chain of the native potato. The primary sources of information used in the research come partly from UPM cooperation project, "Improving the value chain of Andean potato as a boost to rural development. Case Three Rural Communities in the Province of Jauja, (Perú)", in which the Ph.D. student was involved, and partly from the surveys, which were specifically designed for the different links of the value chain of the native potato. The secondary sources of information come from academic articles, from articles published by magazines of the industry, and from reports of several government institutions, both Spanish and Peruvian. The conclusions of the research are as follows. The creation of the commonwealth of Yacus has benefited small farmers. They get better sales conditions and better prices for their products, which results in the improvement of their living conditions. These improvements are due to a value chain of native potato which is working effectively. All the firms invited to constitute the value chain have shown interest in being part of it: the farmers to get better prices for their products and better sale conditions; the distributors to ensure a certain quality of fixed varieties of native potato, the processing industry in order to have an adequate supply of product to the corresponding derivative of native potato (chips, “tunta”, etc.); exporting firms to have a guaranteed supply of the products that they require with the right volumes. It's a win-win situation for all participating companies. Despite being a traditional product, the value chain of the native potato presents innovation in marketed products, (both fresh native potato and its derivatives), in the formats of products, in the distribution network, in Peruvian institutions and in relation with the consumer. There is a perceived demand of native potato and its products in countries where communities of Latin Americans have settled down. Spain is among the countries that have received a significant number of people from Latin America. Despite the strong economic crisis suffered by Spain, which has lead to a return to their home countries of part of the Latin American community, the size of this population is still considerable. This population demands products from their own countries, and they frequently consume them if the prices are suitable to their standard of living. The selling price of the native potato and its derivatives in Spain is of great importance. The import of these products from Perú makes the prices rise to levels that reduce competitiveness, especially in fresh native potatoes. It is advised to look for companies which can adapt the fresh potato production in our country, and keep direct export to Spain for the derivatives products. The preferences of Peruvian and Spanish consumers in terms of formats and brands are not the same. The surveys concluded that the same marketing strategy cannot be followed in both countries. Packet formats of native potato and its derivatives should be differentiated in Spain and Perú, in order to reach the potential consumers of both countries.

Estudio comparativo y completo de la oferta de software libre para centros de educación primaria

La Organización de Estados Iberoamericanos para la Educación, la Ciencia y la Cultura (OEI) pretende llevar energía solar y acceso a internet a más de 66.000 escuelas en Iberoamérica, la mayor parte de ellas ubicadas en zonas rurales y de difícil acceso. Con el proyecto “Luces para aprender” se quiere reducir la brecha digital y poner fin al aislamiento de las comunidades rurales, facilitando su acceso a las tecnologías de la comunicación, con el fin de favorecer su desarrollo educativo, económico, social y cultural. La OEI que coordina el proyecto “Luces para Aprender” se dirigió a TEDECO (Tecnología para el Desarrollo y la Cooperación), que es un grupo de cooperación al desarrollo de la Facultad de Informática de la UPM, para solicitar asesoramiento en la parte software a instalar en el proyecto. Surge la necesidad de dotar de sistema operativo a los computadores que tendrán las escuelas beneficiarias de este proyecto. Por lo tanto, se ha decido crear un sistema operativo que consiste en una distribución GNU/Linux que se adapte a las necesidades de dicho proyecto. Esta distribución va acompañada de un manual de usuario y una guía de instalación para facilitar la implantación en los respectivos centros. Se pretende que la distribución esté disponible en un repositorio web y además esté basada en la filosofía de código libre y abierto. ---ABSTRACT---The OEI (Organization of Ibero-American States for Education, Science and Culture) hopes to provide solar energy and Internet access to more than 66.000 schools in Ibero-America, most of them, located in rural zones and of difficult access. With the project “Luces para aprender” (lights to learn), they would like to reduce the digital gap and put an end to the deprivation of the rural communities, supplying access to the Information Technologies, with the aim of contributing to its educative, economic, social and cultural development. The OEI that coordinates "Luces para Apreder" project, requested TEDECO (Technology for Development and Cooperation), which is a group of development cooperation of Facultad de Informática of the UPM, to advice in the part of software installation in the project. There is a need for an operative system that the computers will have in schools that will benefit from that project.

That distribution will be accompanied by a user’s manual and an installation guide to help the implementing in the centres. The distribution is supposed to be available in a web, and moreover, will be based on the philosophy of free and opened codes.

Land cover dynamics and climate change implications on water resources in South Pacific Costa Rica

Water is fundamental to human life and the availability of freshwater is often a constraint on human welfare and economic development. Consequently, the potential effects of global changes on hydrology and water resources are considered among the most severe and vital ones. Water scarcity is one of the main problems in the rural communities of Central America, as a result of an important degradation of catchment areas and the over-exploitation of aquifers. The present Thesis is focused on two critical aspects of global changes over water resources: (1) the potential effects of climate change on water quantity and (2) the impacts of land cover and land use changes on the hydrological processes and water cycle. Costa Rica is among the few developing countries that have recently achieved a land use transition with a net increase in forest cover. Osa Region in South Pacific Costa Rica is an appealing study site to assess water supply management plans and to measure the effects of deforestation, forest transitions and climate change projections reported in the region. Rural Community Water Supply systems (ASADAS) in Osa are dealing with an increasing demand of freshwater due to the growing population and the change in the way of life in the rural livelihoods. Land cover mosaics which have resulted from the above mentioned processes are characterized by the abandonment of marginal farmland with the spread over these former grasslands of high return crops and the expansion of secondary forests due to reforestation initiatives. These land use changes have a significant impact on runoff generation in priority water-supply catchments in the humid tropics, as evidenced by the analysis of the Tinoco Experimental Catchment in the Southern Pacific area of Costa Rica. The monitoring system assesses the effects of the different land uses on the runoff responses and on the general water cycle of the basin. Runoff responses at plot scale are analyzed for secondary forests, oil palm plantations, forest plantations and grasslands. The Oil palm plantation plot presented the highest runoff coefficient (mean RC=32.6%), twice that measured under grasslands (mean RC=15.3%) and 20-fold greater than in secondary forest (mean RC=1.7%). A Thornthwaite-type water balance is proposed to assess the impact of land cover and climate change scenarios over water availability for rural communities in Osa Region. Climate change projections were obtained by the downscaling of BCM2, CNCM3 and ECHAM5 models. Precipitation and temperature were averaged and conveyed by the A1B, A2 and B1 IPCC climate scenario for 2030, 2060 and 2080. Precipitation simulations exhibit a positive increase during the dry season for the three scenarios and a decrease during the rainy season, with the highest magnitude (up to 25%) by the end of the 21st century under scenario B1. Monthly mean temperature simulations increase for the three scenarios throughout the year with a maximum increase during the dry season of 5% under A1B and A2 scenarios and 4% under B1 scenario. The Thornthwaite-type Water Balance model indicates important decreases of water surplus for the three climate scenarios during the rainy season, with a maximum decrease on May, which under A1B scenario drop up to 20%, under A2 up to 40% and under B1 scenario drop up to almost 60%. Land cover scenarios were created taking into account current land cover dynamics of the region. Land cover scenario 1 projects a deforestation situation, with forests decreasing up to 15% due to urbanization of the upper catchment areas; land cover scenario 2 projects a forest recovery situation where forested areas increase due to grassland abandonment on areas with more than 30% of slope. Deforestation scenario projects an annual water surplus decrease of 15% while the reforestation scenario projects a water surplus increase of almost 25%. This water balance analysis indicates that climate scenarios are equal contributors as land cover scenarios to future water resource estimations.

Modelo de análisis organizativo para la mejora del desempeño de empresas sociales

La empresa social es un modelo organizativo que presenta un interesante potencial para resolver problemáticas sociales. La empresa social ha despertado interés tanto en países industrializados como en economías en vías de desarrollo porque representa un modelo dentro del capitalismo que persigue objetivos sociales mediante la realización de actividades de mercado (compra y venta de productos y/o servicios principalmente). A pesar de sus raíces lejanas en el tiempo se trata de un campo de conocimiento relativamente joven, donde la literatura académica presenta escasez de estudios empíricos. El desarrollo teórico para buscar claridad conceptual ha sido el principal caballo de batalla de los últimos años, y por tanto, se ha prestado poca atención a generar evidencias sobre cómo funcionan las empresas sociales y sobre sus claves de su éxito. Se considera que la mejora en la comprensión de este modelo organizativo pasa por la construcción de herramientas para que académicos y practicantes mejoren su conocimiento sobre los mecanismos internos de las empresas sociales. En este contexto nace la presente tesis doctoral sobre empresa social, que tiene por objetivo la creación de un marco de análisis que permita el estudio de las empresas sociales desde una dimensión organizativa, es decir, que aborde los elementos clave que describen el funcionamiento de este tipo de organizaciones. Para ello, en este trabajo se aborda la construcción del modelo para el análisis organizativo de las empresas sociales a partir del análisis semántico de las 45 principales definiciones de empresa social. A partir de este análisis se identifican dos dimensiones de análisis de la empresa social: -Cuatro principios, comunes a todas las manifestaciones del fenómeno, que recogen la esencia del concepto. -Ocho elementos organizativos específicos de la empresa social que describen la forma en la que cada iniciativa se implementa en un contexto determinado. Es decir, elementos de diseño presentes en diferente medida que dan lugar a tipologías de empresa social diferentes. Estos elementos son: la proposición de valor social, la búsqueda de impacto a largo plazo, la cultura organizativa, la conexión con los beneficiarios, el liderazgo emprendedor y los mecanismos de gobernanza, el ecosistema colaborativo, la estrategia empresarial y la orientación a la autosuficiencia económica. A partir de este marco de análisis, se construyen dos herramientas de diagnóstico que permiten su aplicación al estudio de empresas sociales: una tabla de indicadores para el análisis externo (por parte de un investigador ajeno a la organización) y un cuestionario de diagnóstico para el análisis interno (a través del personal de la empresa social objeto de estudio). Las herramientas intentan dar respuesta a la necesidad de desarrollar constructos para el estudio empírico de las empresas sociales. Para analizar la utilidad del modelo y de las herramientas se llevaron a cabo tres estudios de caso: -La empresa social ACCIONA Microenergía Perú que proporciona energía eléctrica a comunidades rurales aisladas en la región peruana de Cajamarca. -La empresa social Integra-e que propone un mecanismo de inserción socio-laboral en Madrid para jóvenes en riesgo de exclusión a través de la formación en Tecnologías de la Información y la Comunicación (TIC). -Un conjunto de redes de telecentros pertenecientes a la red LAC de la fundación Telecentres.org que proporcionan acceso a servicios de información (Internet entre otros) en diferentes países de Latinoamérica. La aplicación de las herramientas mostró ser útil en los tres estudios de caso para obtener una relación de evidencias con las que analizar la proximidad de una organización al ideal de empresa social. El ejercicio de análisis también resultó interesante como ejercicio reflexivo para las entidades participantes. Los resultados del cuestionario fueron especialmente interesantes en los telecentros de la Fundación Telecentre.org ya que al ser un estudio multicaso se pudo realizar un rico análisis estadístico sobre el funcionamiento de los telecentros y su desempeño. El estudio permitió identificar relaciones interesantes entre los ocho elementos de diseño del modelo propuesto y el desempeño de la organización. En particular, se detectó que para todos los casos estudiados: -La dimensión económica es la componente del desempeño que mayor desafíos plantea. -La existencia de una alta correlación entre el desempeño y siete de los ocho elementos organizativos del modelo. -La importancia de la cultura organizativa como elemento que explica el desempeño global de la organización y la satisfacción de los empleados. El campo de la empresa social presenta importantes retos de futuro, como la claridad conceptual, el desarrollo de estudios empíricos y la medida de su impacto social. El conocimiento de las claves organizativas puede ayudar a diseñar empresas sociales más robustas o a que organizaciones con fines sociales que no se basan en mecanismos de mercado consideren la posibilidad de incorporar éstos en su estrategia. ABSTRACT Social enterprise is an organizational model with a strong potential to help solving social problems. Recently, interest for the model has risen in both industrialized and developing countries because it is organized to achieve altruistic or social goals through market activities (mainly sales of products and services). Despite its historic roots, it is a relatively young field of research, where academic literature has little empirical data to accompany the theoretical development of social enterprise. Conceptual clarification has been the main challenge during the recent years, and there has been little attention given to generate evidence on how social enterprises operate and their keys to success. Progress in empirical study involves the construction of tools for researchers, in order to increase understanding of the internal mechanisms of social enterprises. This thesis aims to create a conceptual framework to study social enterprises from an organizational point of view, by analyzing the key elements that explain the operation and organization of this organizational model. The framework for the organizational analysis of social enterprises was built supported by the semantic analysis of 45 main definitions of social enterprise. The framework is divided into two dimensions: -There are four principles which capture the essence of the social enterprise concept, and are present in the manifestations of cases. -There are eight design elements which help analyze the characteristics of each particular social enterprise initiative: the social value proposition, social impact orientation, organizational culture, links to beneficiaries, entrepreneurial leadership, collaborative ecosystem, entrepreneurial strategy and orientation to economic self-sufficiency. Two diagnostic tools were developed to apply the framework to case studies: a scoreboard of indicators (to be used by the researcher during external analysis of the organization) and a questionnaire (to be answered by the social enterprise staff). The dissertation undertakes the study of three case studies: -ACCIONA Microenergia Peru, a social enterprise that provides electricity to isolated rural communities in the Peruvian region of Cajamarca. -Integra-e, a social enterprise located in Madrid that promotes socioprofessional integration of young people through training in ICT. -A sample of telecenters of the LAC network that provide access to information services (such as Internet) in Latin America. Applying the tools proved to be useful in all three cases, because it helped to obtain evidence to compare the proximity of an organization to an ideal type of social enterprise. In all the cases studied, the economic sustainability proved to be the biggest challenge for the organizations. The application of the questionnaire to the telecenters was especially informative because it was a multicase study which provided a rich statistical analysis on the performance of call centers. The study identified unique relationships between the model elements and the organziation performance. A statistical analysis shows a high correlation between performance and seven organizational elements described in the model. The organizational culture seems to be an important factor in explaining the overall organizational performance and employee satisfaction. The field of social enterprise has significant future challenges -such as conceptual clarity, the development of empirical studies and social impact assessment. A deep understanding of key organizational aspects of social enterprises can help in the design of more robust organizations and to bring success to social-purpose organizations.

Estudio para un Modelo de Gestión de un Acuífero Costero, mediante Metodologías Participativas y Análisis Geoestadístico en el marco del Desarrollo Local. Manglaralto, Ecuador

El presente estudio se fundamenta en la investigación-acción-participativa (IAP), para buscar alternativas que tiendan al desarrollo local de un territorio. Se centra en la cuenca hidrográfica del rio Manglaralto-Santa Elena-Ecuador, aplicando un sistema metodológico participativo que considera las características peculiares del territorio, que se analizan geoespacialmente reconociendo la influencia de la dinámica de sus cambios y observando los móviles que la propiciaban. A través de mecanismos participativos, se conectan los aspectos técnicos para el conocimiento y el aprovechamiento racional del acuífero costero, con los valores de los habitantes del territorio, para mejorar su abastecimiento de agua y crear nuevas condiciones y oportunidades en el camino del desarrollo local, vislumbrando la sostenibilidad. Cabe indicar que el ente administrativo y propulsor es la Junta de Agua Potable Regional Manglaralto (JAPRM). La hipótesis del estudio considera, que los métodos participativos generan en la comunidad una respuesta basada en su identidad y sus deseos de mejorar, que propiciará una gestión del acuífero costero que conlleve al desarrollo local. Otra hipótesis complementaria estipula que las estrategias del gobierno respecto al turismo propicia un crecimiento en la demanda del agua del acuífero. En Manglaralto-Ecuador, una parroquia de 30.000 habitantes aproximadamente, donde la JAPRM, administra y suministra agua a 23.586 habitantes que cuenta en su organización, llevada por 6 representantes de las comunidades rurales que la conforman, empezaron hace 7 años a buscar una forma de lograr un cambio, de tener agua para el desarrollo de la comunidad. Buscaron ayuda por diferentes medios, políticos, económicas, sociales y encontraron como base fundamental a la cooperación con el Organismo Internacional de Energía Atómica (OIEA) y la Escuela Superior Politécnica del Litoral (ESPOL) para entrelazar aspectos técnicos, ambientales, sociales y culturales. La gestión del acuífero costero, desde la perspectiva del IAP repercute en el desarrollo de Manglaralto. También se realiza un análisis geoespacial-geoestadístico, para vislumbrar aspectos de cambios en el territorio ligados al crecimiento turístico, que afectan a la demanda del recurso agua proveniente del acuífero costero bajo la administración de la JAPRM. La tesis presenta el modelo integral y propio de la comunidad de Manglaralto, que refleja una evolución que alcanzó un apogeo en 2011 y parte del 2012, con 9 pozos de agua que daban servicio los 365 días del año, 24 horas al día ininterrumpidamente. Las condiciones externas (promociones turísticas de la ruta del Spondylus) han repercutido en nuevas problemáticas (crecimiento elevado de la demanda del agua). El acuífero costero se convierte en el emblema y móvil de solución, gracias a la gestión integral y a la interacción IAP que se amolda a la evolución de las condiciones, buscando soluciones para la comunidad y su entorno. El modelo integral del territorio con la participación de sus pobladores, considera el aspecto turístico, como un agente que propicia la mayor demanda del agua. Situación a la que hay que dar respuesta mediante la observación-reflexión en el ciclo del IAP para generar nuevas directrices estratégicas y gestionar el desarrollo local. ABSTRACT The present study is based on the participatory action research (PAR) methodology in order to look for alternatives which tend to the local development of a territory. It focuses on the Manglaralto hydrographic river basin located in Santa Elena-Ecuador through the application of the participatory methodology which considers the peculiar characteristics of the territory. These are geospatially analyzed recognizing the influence of its dynamic of changes and observing the causes that originated them. Through the use of participatory mechanisms, technical aspects are connected for stimulating knowledge and rational use of the coastal aquifer with the values of inhabitants of the territory to improve the water supply and create new conditions of sustainability. It is important to point out that the administrative organism and promoter is the Manglaralto Regional Fresh Water Board (JAPRM). In Manglaralto-Ecuador, a parish of approximately 30,000 inhabitants, the MRFWB manages and supplies water to 23.586 inhabitants. This organization is composed by 6 representatives of rural communities. It started 7 years ago looking for a way to achieve a change, from obtaining water to developing the community. They seeked for help in different fields such as: political, economic and social and they found International Atomic Energy Agency (IAEA) and Escuela Superior Politécnica del Litoral (ESPOL) as a fundamental basis for cooperation to bond technical, environmental, social and cultural aspects. Management of coastal aquifer, from the PAR perspective affects the development of Manglaralto. Also, a geospatial and geostatistical analysis is carried out to distinguish change aspects in territories related to touristy growth which affects the demand of water obtained from the coastal aquifer under the management of the MRFWB. The thesis presents a comprehensive model that belongs to the Manglaralto community and reveals an evolution that reached a peak in 2011 and part of 2012, with 9 water wells that operated the 365 days of the year 24 hours a day without interruption. The external conditions (touristic packages of Spondylus route) have created new problems (higher demand of water). The coastal aquifer is a symbol and solution, thanks to the comprehensive management and PAR interaction which fits the evolution of conditions, looking for solutions for the community and its surroundings. The comprehensive model of territory with the participation of inhabitants considers the touristic aspect as an agent which brings about a higher demand of water. This situation requests a response through the observation-reflection in the PAR cycle to generate new strategic guidelines and promote the local development.

Gestão de embalagens vazias de agrotóxicos - logística reversa em pequenos municípios brasileiros: o caso do município de Bom Repouso, MG

O Brasil assumiu e mantém desde 2008 o primeiro lugar mundial em consumo de agrotóxicos e, tendo em vista este uso intensivo, é possível estimar a grande quantidade de embalagens vazias de agrotóxicos (EVAs) geradas todos os anos no país. Com a promulgação da Lei 9974 de 2000, a criação do Instituto Nacional de Processamento de Embalagens Vazias (inpEV) em 2001 e a implantação da Política Nacional de Resíduos Sólidos (PNRS) em 2010, a destinação adequada das EVAs por meio da logística reversa passou a ocorrer de maneira mais eficiente, chegando a um percentual de 94% de devolução em 2014 segundo dados do INPEV. No entanto, este processo foi originalmente concebido para atender grandes áreas rurais, com economias de escala que o favorecem, e portanto não está adequado à realidade de pequenas comunidades rurais, geralmente com infraestrutura precária e mais isoladas. Sendo assim, ainda é comum nos municípios de pequeno porte que essas embalagens sejam queimadas, armazenadas em locais não adequados ou simplesmente abandonadas no campo. Dessa forma, o objetivo deste estudo foi analisar a gestão de EVAs em pequenos municípios agrícolas brasileiros, com foco no processo de logística reversa, a partir de um estudo de caso. Este foi realizado em Bom Repouso, MG, município de 10500 habitantes, caracterizado pela produção de morango e batata, com mão de obra familiar e uso intensivo de agrotóxicos. As seguintes etapas de pesquisa foram desenvolvidas: entrevistas semiestruturadas com os atores da cadeia de logística reversa de EVAs; levantamento documental; análise comparativa entre a quantidade de embalagens vendidas e a quantidade total de embalagens devolvidas entre os anos de 2012-2013 e 2013-2014, bem como um levantamento dos agrotóxicos mais comercializados no município. Verificou-se que, no período 2012-2013, a quantidade de embalagens vendidas foi cerca de 30 vezes maior que a de embalagens devolvidas, e para o período entre 2013-2014 a mesma relação foi da ordem de 26 vezes. Além disso, a massa total de embalagens devolvidas corresponde a apenas 3,3% da massa de vendidas no período 2012-2013, e 3,8% para 2013-2014. Ou seja, aproximadamente 96% das embalagens comercializadas em ambos os períodos não foram devolvidas à central de Pouso Alegre. Além disso, há produtos extremamente tóxicos para a saúde e para o meio ambiente entre os 20 mais vendidos no município. Não estão estabelecidas políticas públicas municipais voltadas à gestão desses resíduos, como pode ser verificado através das entrevistas e do levantamento documental. Dificuldades relacionadas ao armazenamento das EVAs até o momento da devolução e seu transporte até a Central de Recolhimento foram apontadas pelos entrevistados como principais motivos para não cumprir suas responsabilidades e, consequente, descartar inadequadamente esses resíduos.

Developing Autonomous Microgrids: A Theoretical Case Study

Microgrids are autonomously operated, geographically clustered electricity generation and distribution systems that supply power in closed system settings; they are highly compatible with renewable energy sources and distributed generation technologies. Mocrogrids are currently a serially underutilized and underappreciated commodity in the energy infrastructure portfolio worldwide. To demonstrate feasibility under poor conditions (little renewable energy potential and high demand) this capstone project develops a theoretical case study in which a renewable microgrid is employed to power rural communities of southern Montgomery County, Arkansas. Utilizing commercially manufactured 1.5-megawatt wind turbines and a 1-megawatt solar panel generation system, 4-megawatts of lithium ion battery storage, and demand response technology, a microgrid is designed that supplies 235 households with reliable electricity supply.

La lucha por la tierra en la Huasteca Potosina (México): de peones a patrones

El presente trabajo consiste en un análisis acerca de las luchas por la tierra que se han venido produciendo en la región mexicana de la Huasteca Potosina, principalmente a raíz de la puesta en marcha del proyecto Pujal-Coy en 1973, cuando ocurre una transformación espacial que provoca toda una serie de conflictos por la apropiación del territorio a manos de nuevos pobladores frente a las instancias de gobierno encargadas del reparto agrario. Este proceso aparecerá marcado por la transformación del estatus socioeconómico de un importante colectivo en el momento en el que se convierten en propietarios de tierras. La metodología desarrollada es de carácter interdisciplinar al combinar el análisis geopolítico a escala local, el trabajo etnográfico en comunidades rurales y la revisión histórica. El resultado de la investigación ha sido la comprensión de la lógica espacial que define a esta región de México a partir de las contradicciones entre las prácticas espaciales hegemónicas y los contra-espacios que las poblaciones locales construyen como alternativa a las primeras.
