The improvement is particularly noteworthy being an increase of almost 20 points from 2009 to 2014 [97]. Such a dramatic The existence of models of environmental segregation is strongly associated with the development of socially segregated cities [95].…”

In recent decades, urban processes have experienced deep transformations. One of them has been the growing importance of urban sprawl. This article reviews its main features and the policies related to the paradigm of sustainability in three Latin American Megalopolises: Mexico City, Lima, and Santiago de Chile. For this purpose, we have carried out an extensive compilation of the existing academic literature. Urban sprawl in those cities cannot be understood without considering the rising housing needs of popular classes, usually addressed through the sequence settlement-parceling-building-urbanization. Simultaneously high-income groups tend to create separated and gated commodities and there is increasing spatial mobility of the middle classes. Those processes tend to generate highly segregated and increasingly patched metropolitan areas. Sustainability is framed on models of urban governance based on ecological modernization. In this context, three main sustainable policies are analyzed: water supply, green areas provision, and transport. Conclusions stress: (1) Deep changes experienced and the path-dependent element observed in the social construction of sustainability (2) Consolidation of a model of socially segregated and ecologically differentiated urban polycentrism (3) Relevance of the different megalopolises as niches of experimentation and innovation in the construction of specific forms of sustainable transition.

“…Its qualitative orientation with respect to judgments and evaluation procedures meets the typology of data we face in this research; it balances logic with a theoretical basis of the system. The approach has been successfully applied in diverse and multiple research fields such as waste [64], water [65], politics [66], education [67], health [68], mobility and transport [69], and energy [70] among others; for further comparisons, please refer to Weimer-Jehle [71].…”

Challenges for Energy Transition in Poverty-Ridden Regions—The Case of Rural Mixteca, Mexico

2021

View full text Add to dashboard Cite

This paper presents distinct scenario pathways and their storylines resulting from an analysis of interdependencies. We identified the main drivers of a proposed renewable energy transition in rural Mixteca-Puebla, Mexico. By analyzing the main factors involved in alleviating impoverished communities in the rural region, we show the varying degrees to which these drivers influence, support, or hinder a promising energy transition. A Cross-Impact Balance Analysis was conducted to explore the multiple inter-relationships among a set of conditions. This methodology allowed us to evaluate the relationships between social, political, cultural, and environmental variables. The main drivers were identified as clusters of several elements, in which the uncertainties in governance and the legal system trigger the inter-relationship of forces in the area. The focus of this paper is to show how the societal aspects affect the structural energy transformation and its capacity for adaptation in future trends envisioned for the area. This research contributes to the use of technological transformation as a means to alleviate poverty in a rural area. These outcomes give insights regarding the conditions to be considered, in respect to possible–encouraging, but also pessimistic pathways for the region in coming decades.

“…Water resources allocation is expected to be a promising strategy to ensure water supply security, and the analysis of water supply-demand situation is the basic support of water resources macro-allocation. It should also be noted that the water supply-demand situation is likely to change with the advent of new policies and technologies (Schütze et al 2019). In China, the actual water consumption described in China Water Resources Bulletin (Ministry of Water Resources of the People's Republic of China, 2010-2020) is more than 10%lower than the forecasted water demand described in National Integrated Water Resources Plan (Ministry of Water Resources of the People's Republic of China, 2010) in most basins and regions, and ecological water demand is also not taken into consideration in previous plans.…”

Water Supply-Demand Situation Analysis Based on a Hierarchical Index System

In this study, a hierarchical index system is proposed for analysis of water supply-demand situation, which can overcome the shortcomings of complicated analysis and ambiguous decision, associated with the use of a single index like water shortage or water shortage ratio. Five indices responsible for water supply-demand imbalance are considered on both water resources supply and demand sides, and corresponding regulation strategies are proposed to restore water supply-demand balance by improving the water supply capacity of conventional and non-conventional water resources, improving water-use efficiency, and controlling the social and economic development scale. The proposed hierarchical index system has been successfully applied to the analysis of the water supply-demand situation in Qingdao. The results reveal that in order to improve the severe water supply-demand situation in Qingdao, it is necessary to divert water from other regions and improve agricultural water-use efficiency. This study may provide insights into the design and preparation of inter-basin or cross-regional water diversion projects and the formulation of annual water diversion plans.
