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.

Incidencia y especificaciones del hormigón con fibras en las diferentes partes del proyecto en España y Bolivia

En los últimos años es notable la proliferación de trabajos y estudios que tratan sobre las características del hormigón reforzado con fibras, sin embargo su incorporación en el proyecto no está del todo claro, por lo que el presente trabajo se enfocará en describir las fibras y las principales características que estas modifican en el comportamiento del hormigón, tomando en consideración la Normativa EHE-08 y el Código Boliviano del Hormigón (CBH-87).También, trata de implementar el hormigón reforzado con fibras en la elaboración del proyecto, teniendo en cuenta la incidencia de las fibras en las diferentes etapas del mismo. Se compara la influencia del hormigón reforzado con fibras en las diferentes etapas de la elaboración del proyecto en España con la de un proyecto elaborado en Bolivia. Por último, se describen los aspectos a considerar en el control de calidad del hormigón reforzado con fibras a incluir en el proyecto, para una correcta utilización del mismo.

Analysing trade-offs between food production and ecosystem services in tropical forests of lowland Bolivia

The expansion of agricultural land is responsible for most tropical deforestation. Historically, smallholder farming and shifting cultivation has been reported as the main agent of deforestation. However, the increasing global demand for food in recent years has greatly boosted the development of medium and large-scale commercial agriculture which is nowadays causing the majority of tropical forest cover loss, particularly in Latin America.
