Rural Urban Migration

During the second half of the twentieth century, Ecuador went through an intense rural-urban migration that drove a significant increase in the demand for housing units. Insufficient government response resulted in great housing deficit in all the cities. Later, this triggered the formation of pro housing organizations across the country, which looked for quick solutions for the poorest working class. Since the 70s, economic changes driven by the oil boom also contributed to said housing deficit increase along with the growth of urban informality in many cities. Although self-build and self-management housing production fostered urban sprawl over unserved peripheral land, cooperativism became an alternative to tackle the growing scarcity. However, the case of Alianza Solidaria Housing Cooperative stands out among the numerous social organizations that aimed for better living conditions. It developed an alternative for housing production in the periphery of Quito based on a comprehensive vision about habitat, self-management, solidarity-based economy and cooperativism.

Educational Paradigm

Knowledge Society (KS) is influenced by Information and Communication Technologies (ICT), economic changes, political, cultural and social concepts allowing access to other levels of welfare and progress. However, the differences in terms of access and ICT skills between different groups in society have created a problem of digital divide. To overcome this problem, models and strategies are required to achieve a greater impact on the population and that population can develop skills that enhance inclusion in the society knowledge. This work proposes an Interactive Ecosystem of digital literacy that aims to set a new educational paradigm approach to encourage different learning communities to uses new technologies of information and communication that allows them to be more competitive in today's world and thus shorten the digital divide. Finally, a case study is shown as an implementation of the ecosystem throughout an architectural model in the state of Aguascalientes, México.

Forest Tenure

Devolution is a promising tool to enhance forest management. The literature has discussed many factors that affect the outcomes of forest devolution policies; however, insufficient attention has been paid to the role of exogenous socio-economic changes. Using the longitudinal case study method, we focus on how socio-economic changes affect the effectiveness of forest devolution policies using a case from Southeast China. We find that in this case, although forest devolution succeeded in granting farmers sufficient forest rights, it failed to incentivize farmers to contribute to managing forests because of the dramatic changes in socio-economic contexts. Economic development and outmigration reduced farmers’ dependence on forest income, elevated the costs of silvicultural operations, and posed market risks, thereby reducing farmers’ enthusiasm about managing forests; outmigration also weakened community leadership and impeded the collective action of making forest investments. Eventually, socio-economic changes compromised the positive stimulus caused by forest devolution and contributed to the collective action dilemma of managing forests after the reform. We argue that operationalizing forest devolution in developing countries needs to consider the exogenous socio-economic changes that may enhance or counteract the effects of devolution policies, and that more autonomy should be granted to communities to make policies adaptative to their local socio-economic dynamics.

Transformation Processes

Predicted demographic, climatic and socio-economic changes will require adaptations of existing water supply and wastewater disposal systems. Especially in rural areas, these new challenges will affect the functionality of the present systems. This paper presents a joint interdisciplinary research project with the objective of developing an innovative software-based optimization and decision support system for the implementation of long-term transformations of existing infrastructures of water supply, wastewater and energy. The concept of the decision support and optimization tool is described and visualization methods for the presentation of results are illustrated. The model is tested in a rural case study region in the Southwest of Germany. A transformation strategy for a decentralized wastewater treatment concept and its visualization are presented for a model village.
