Eco-entrepreneurship in developing countries: the case of renewable energy sector in Bolivia

The change towards a sustainable economic system represents a big challenge for the present as well as next generations. Such a process requires important long-term changes in technologies, lifestyle, infrastructures and institutions. In this scenario the innovation process is a crucial element for fostering sustainability as well as an egalitarian development in developing countries. For those reasons the concept of Eco-Innovation System is introduced and further considerations are provided for the case of less-developed countries. The paper illustrates that sustainable development is possible by exploiting local potential and traditional knowledge in order to achieve at the same time economic growth, social equality and environmental sustainability. In order to prove such an assumption a specific case study is described: The renewable energy sector in Bolivia. The case study summarizes many important dimensions of the innovation process in developing countries such as technological transfer, diffusion and adaptation, social dimension and development issues.

Composición florística y etnobotánica de las diferentes formaciones vegetales de la provincia de Loja, Ecuador

Pese a que Loja (Ecuador) presenta una gran riqueza ecológica y cultural, ni su patrimonio etnobotánico, ni cómo afecta el uso de las plantas al estado de conservación de los ecosistemas es bien conocido. Por ello se ha realizado un estudio etnobotánico y ecológico para conocer el papel que han jugado las plantas en la cultura tradicional de la provincia y comprender qué factores influyen en su uso. Durante 2006 y 2008 se entrevistó a 770 informantes (196 de ellos vendedores en mercados locales) y se realizaron 373 transectos en 118 remanentes boscosos, 51% indicados por la gente como lugares de recolección. Se ha registrado el saber etnobotánico de 717 especies pertenecientes a 143 familias, la mayoría nativas del Ecuador, 31 de ellas endémicas. Ello supone un 15% de la flora total de Loja. Sin embargo especies introducidas como Matricaria recutita o Eucalyptus globulus están entre las más citadas. La mayor riqueza se obtuvo para las plantas medicinales (509 especies), que se usan sobre todo para tratar las llamadas “inflamaciones internas” (210 especies, Matricaria recutita y Melissa officinalis principalmente) y trastornos del sistema digestivo (188, Matricaria recutita y Mentha pulegium). En los mercados se venden 169 especies, la mayoría para elaborar la bebida típica llamada horchata (65) y para curar “inflamaciones internas” (36). Además se emplean 414 con otros fines (161 para leña, 142 para alimentación humana, 133 para construcción de viviendas y muebles, 98 para artesanías, 89 ornamentales, 27 tintóreas y 72 para otros usos). En los remanentes se inventariaron 19.156 individuos correspondientes a 1440 especies de 153 familias, de las cuales 437 son empleadas por la población. La riqueza media de especies y de plantas útiles fue significativamente mayor en los remanentes recolectados lo cual parece demostrar que la explotación no afecta negativamente a la diversidad de especies al generar variabilidad de hábitats. También se vio que la proporción de especies útiles disminuye en los remanentes más diversos. También se observó que la probabilidad de uso de una especie aumenta con la frecuencia y la abundancia y disminuye con la distancia a los remanentes en los que aparece. Este patrón general no se cumple para las especies medicinales y ornamentales. Estos datos demuestran una gran riqueza de conocimientos tradicionales y una gran vitalidad del uso de muchas especies y corroboran la hipótesis de que los recursos vegetales más accesibles y abundantes son, salvo excepciones, los más empleados por la gente. ABSTRACT Although the Loja province (Ecuador) has a great ecological and cultural richness, neither the ethnobotanical heritage nor the incidence of plant use on ecosystems conservation it is well known. We have made an ethnobotanical and ecological study to determine the role played by plants in the traditional culture of the province and to understand what factors influence their use. Between 2006 and 2008 we interviewed 770 informants (196 of them vendors in local markets) and inventoried 373 transects in 118 forest remnants (51% of them indicated by people as collection sites). We recorded the ethnobotanical knowledge for 717 species belonging to 143 families, mostly native of Ecuador, 31 of which are endemic. This represents about a 15% of the total flora of Loja. However introduced species such as Matricaria recutita and Eucalyptus globulus are among the most cited. Medicinal plants (509 species) were the most abundant, and are used primarily to treat so‐called "internal inflammation" (210 species, with Matricaria recutita and Melissa officinalis as the most valued) and disorders of the digestive system (188, Matricaria recutita and Mentha pulegium). We recorded 169 species sold in markets, most of them (65) employed to elaborate a typical drink called horchata and to heal "internal inflammation" (36). In addition 414 are used for other purposes: 161 for firewood, 142 for human consumption, 133 for construction and furniture, 98 for handicrafts, 89 as ornamental, 27 for dye and 72 for other uses. In the forest remnants, 19,156 individuals corresponding to 1440 species of 153 families, 437 of which are used by the population were inventoried. The average species richness (both total and of useful plants) was significantly higher in exploited remnants, which suggest that exploitation does not adversely affect species diversity and instead increases habitat diversity. We also found that the proportion of useful species decreases in decreased in the most diverse remnants. It was also observed that the probability of use of a species increases with its frequency and abundance and decreases as the distance form localities to remnants where it appears increases. This general pattern however does not hold for medicinal and ornamental species. These results show the extraordinary wealth of traditional knowledge and the great vitality in the use of many species and support the hypothesis that most accessible and abundant plant resources are the most used by people.

Dimensión territorial de los sistemas alimentarios locales. El caso de Madrid

Una de las características definitorias del sistema urbano contemporáneo es su desterritorialización, es decir, su adopción de un modelo de desarrollo que se da al margen del territorio concreto que lo sustenta y de los recursos biofísicos y culturales existentes en él. Dicha desterritorialización es posible gracias al uso intensivo de energía que ha permitido ampliar hasta la escala global los flujos del metabolismo urbano. De este modo se han roto las relaciones de proximidad urbano-rurales, y se ha aumentado la dependencia de recursos externos. Entre las diferentes manifestaciones de esta desterritorialización se encuentra la organización del sistema alimentario, que en la actualidad responde a un modelo globalizado, en el que la distancia entre producción y consumo ha aumentado a costa de incrementar el gasto energético en transporte y conservación de alimentos. Este distanciamento físico va acompañado también de un distanciamiento social e identario, con la hegemonía de un modelo agroindustrial que no respeta los paisajes, las prácticas agrícolas, los conocimientos tradicionales ni las variedades genéticas locales. Tanto el modelo territorial como el alimentario son altamente vulnerables ante crisis externas que pueden alterar su funcionamiento. El enfoque (bio)regionalista desde el mismo inicio de la ciudad industrial hasta nuestros días ha propuesto un modelo de ordenación territorial alternativo, adaptado a las condiciones locales y basado en la proximidad, que dotaría al sistema territorial de mayor resiliencia y sostenibilidad. Para confirmar este presupuesto y evaluar la capacidad de reterritorialización alimentaria se ha desarrollado una metodología que aborda el estudio del sistema territorial como socioecosistema complejo, en el que se distinguen componentes de tipo social, construido y biofísico, que se encuentran interrelacionados. La historia de cambios en la organización del sistema, su estado actual y su capacidad de reorganizarse en estados alternativos son las bases de dicha evaluación. Esta metodología se aplica a la Comunidad de Madrid con el fin de describir su sistema territorial desde el punto de vista del abastecimiento alimentario y evaluar su capacidad de reterritorialización. ABSTRACT Deterritorialization is one of the defining characteristics of the contemporary urban system. This means that its development model is designed ignoring the attributes of the specific region in which is located, and the biophysical and cultural resources therein. Such territorialization is possible due to the intensive energy consumption that allows expanding to a global scale the flows of urban metabolism. This way, urban-rural linkages have been broken, increasing dependency on external resources. The modern food system is among the clearest expressions of a deterritorialized model. In a globalized food system, increasing distances between production and consumption spaces are possible through energy-intensive transport and preservation activities. Physical distanciation goes hand in hand with social disconnection and loss of identity, due to a hegemonic agro-industrial model that does not respect local landscapes, agricultural practices, traditional knowledge or genetic varieties. Both the regional and the food systems are highly vulnerable to external shocks that may affect their functions. The bioregionalist approach has proposed, since the industrial city until today, an alternative model, adapted to local conditions and rooted on proximity, which provides a sustainable and resilient regional planning and management. To confirm this assumption and assess the food reterritorialisation capacity, a methodology has been developed that address the regional system as a complex social-ecosystem, in which interrelated social, built and biophysical subsystems are included. Assessment is based in the analysis of regimes shifts in the history of the system, and in the description of its current and alternative states. This methodology is applied to the administrative region of Madrid in order to describe its regional food system and assess its reterritorialization capacity.

The introduction of teaching innovations into the traditional teaching of construction and building materials

The traditional teaching methods used for training civil engineers are currently being called into question as a result of the new knowledge and skills now required by the labor market. In addition, the European Higher Education Area is requesting that students be given a greater say in their learning. In the subject called Construction and Building Materials at the Civil Engineering School of the Universidad Politécnica de Madrid, a path was set three academic years ago to lead to an improvement in traditional teaching by introducing active methodologies. The innovations are based on cooperative learning, new technologies, and continuous assessment. The writers’ proposal is to offer their experience as a contribution to the debate on how students can be encouraged to acquire the skills currently demanded from a civil engineer, though not overlooking solid, top-quality training. From the outcomes obtained, it can be concluded that using new teaching techniques to supplement a traditional approach provides more opportunities for students to learn while boosting their motivation. In our case, the introduction of these changes has resulted in an increased pass rate of 29% on average, when such a figure is considered in the light of the mean value of passes during the last decade.

Knowledge Management and Leadership in the Higher Education: A First Approach

Today, it is more and more important to develop competences in the learning process of the university students (that is to say, to acquire knowledge but also skills, abilities, attitudes and values). This is because professional practice requires that the future graduates design and market products, defend the interests of their clients, be introduced in the Administration or, even, in the Politics. Universities must form professionals that become social and opinion leaders, consultants, advisory, entrepreneurs and, in short, people with capacity to solve problems. This paper offers a tool to evaluate the application for the professor of different styles of management in the process of the student’s learning. Its main contribution consists on advancing toward the setting in practice of a model that overcomes the limitations of the traditional practices based on the masterful class, and that it has been applied in Portugal and Spain.

Traditional education vs modern education. What is the impact of teaching techniques' evolution on students learning process?

The main objective of this article is to focus on the analysis of teaching techniques, ranging from the use of the blackboard and chalk in old traditional classes, using slides and overhead projectors in the eighties and use of presentation software in the nineties, to the video, electronic board and network resources nowadays. Furthermore, all the aforementioned, is viewed under the different mentalities in which the teacher conditions the student using the new teaching technique, improving soft skills but maybe leading either to encouragement or disinterest, and including the lack of educational knowledge consolidation at scientific, technology and specific levels. In the same way, we study the process of adaptation required for teachers, the differences in the processes of information transfer and education towards the student, and even the existence of teachers who are not any longer appealed by their work due which has become much simpler due to new technologies and the greater ease in the development of classes due to the criteria described on the new Grade Programs adopted by the European Higher Education Area. Moreover, it is also intended to understand the evolution of students’ profiles, from the eighties to present time, in order to understand certain attitudes, behaviours, accomplishments and acknowledgements acquired over the semesters within the degree Programs. As an Educational Innovation Group, another key question also arises. What will be the learning techniques in the future?. How these evolving matters will affect both positively and negatively on the mentality, attitude, behaviour, learning, achievement of goals and satisfaction levels of all elements involved in universities’ education? Clearly, this evolution from chalk to the electronic board, the three-dimensional view of our works and their sequence, greatly facilitates the understanding and adaptation later on to the business world, but does not answer to the unknowns regarding the knowledge and the full development of achievement’s indicators in basic skills of a degree. This is the underlying question which steers the roots of the presented research.

Influencia del tratamiento "a fuego" en las características del estuco tradicional con cal = Influence of treatment "by fire" in the characteristics of traditional lime stucco

Esta investigación avanza en el intento de recuperar la técnica tradicional del estuco a fuego, paradigma de la decoración de espacios interiores hasta la mitad del s. XX por sus imitaciones marmóreas de gran calidad. Para ejecutarlos se utilizaban morteros de cal con áridos de mármol, pigmentos minerales y grasas; con estos materiales se preparaban y tendían las masas, se pintaban al fresco y se terminaban con el paso de una herramienta metálica caliente. Como sucede con otras técnicas, el paso del tiempo ha difuminado los conocimientos sobre la materia, haciendo muy difícil la conservación o restauración de los ejemplos en nuestro patrimonio. A partir de la escasa bibliografía existente se ha recuperado el proceso, sometiendo las muestras elaboradas a diferentes ensayos que han caracterizado el acabado final,tanto en sus características intrínsecas como en las que le son conferidas al proteger finalmente las muestras con una capa de cera, tal y como se realizaba tradicionalmente.---ABSTRACT---This research advances in the attempt to recover the traditional technique of stucco by fire; paradigm of indoor decoration until half of 20th century due to its high quality marbled imitations. On its implementation process, it was used lime mortars with marble aggregates, mineral pigments and greases. With these materials, masses were prepared and extended into the walls, they were painted in fresco and ended with the passage of a heated metal tool. As with any other technique, the time passing over has blurred the knowledge on the subject, making very difficult the preservation or restoration of examples in our heritage. Despite of the limited literature, the process has been recovered; subjecting the samples prepared at different trials that have characterized the finished, both in its merits and its conferred characteristics by finally protecting the samples with a layer of wax, as was done traditionally.
