According to the UN, in the next 20 years, most of the world’s population will live in urban areas. Cities consume a high amount of resources, between this water, for their sustenance, hence the greatest necessity of sustainable development plans. What viable options or strategies can we consider in Latin America such that it can resist the economic, political, and social changes that it is facing? Through prospective studies, in case of Guadalajara, it is possible to determinate how water can generate clean energy, and which are the other strategic areas to empower the city through decarbonization with an interoperative and smart loop system of co-benefits. This study can help in public policy decisions of medium-sized cities in Latin America.

Abstract Background Currently, most of the world’s population lives in cities, and the rapid urbanization of the population is driving increases in the demand for products, goods and services. To effectively design policies for urban sustainability, it is important to understand the trends of flows in energy and materials as they enter and leave a city. This knowledge is essential for determining the key elements characterizing future urban growth and addressing future supply challenges. Methods This paper presents an analysis of the energy and material flows in the city of Bogotá over the time span from 2001 to 2017. Urban flows are also characterized in terms of their temporal evolution with respect to population growth to compare and identify the changes in the main input flows, wealth production, emissions and waste in the city. Results The results of the analysis are then compared with those for other selected large urban agglomerations in Latin America and worldwide to highlight similarities and make inferences. The results show that in Bogotá, there was a decrease in some of the material flows, such as the consumption of water and the generation of discharge, in recent years, while there was an increase in the consumption of energy and cement and in the production of CO2 emissions and construction materials. Solid waste production remained relatively stable. With respect to the other large cities considered, we observe that the 10-year growth rates of the flows with respect to population growth are lower in Bogotá, particularly when compared with the other urban agglomerations in Latin America. Conclusions The findings of this study are important for advancing characterizations of the trends of material and energy flows in cities, and they contribute to the establishment of a benchmark that allows for the definition and evaluation of the different impacts of public policy while promoting the sustainability of Bogotá in the coming decades.

The City of Montreal initiated a First Strategic Plan for Sustainable Development in 2005 followed by a Community and Corporate Sustainable Development Plan in 2010–2015. This study proposes a sustainable urban development indicator (SUDI) for each Montreal Urban Community (MUC) to evaluate the achievements of sustainable development plans. This study identifies thirty-two variables as the attributes of sustainable urban development. The multivariate technique and Exploratory Spatial Data Analysis are applied to determine the spatial pattern of SUDI for each MUC. The spatial pattern of SUDI identifies that Ville Marie, Verdun, Sud-Ouest, Mercier-Hochelaga-Maisonneuve and Plateau Mont-Royal have strong sustainable development. The findings of this study help the City of Montreal to understand the improvement of the sustainable development plans for Montreal city and to distribute the municipal budget for the community benefits accordingly.

This scientific research was conducted to find out the description of the implementation of the Regional Regulation on Regional Spatial Planning in realizing environmentally sustainable development in Bengkulu Tengah Regency. The focus of this research is on the implementation of the policy of providing Green Open Space in the development of urban areas, namely the City Parks that have been built. The method used in this study uses descriptive qualitative methods with a case study approach. Data analysis is based on techniques commonly used in communication messages, namely data collection, data classification, data interpretation and meaning of research results. The results of the study were viewed from four aspects, namely the determination of zoning, licensing issues, choice of incentives and disincentives, and community participation. From this aspect, it is known that in the construction of City Parks as a form of implementation of the policy of providing Green Open Space in the development of urban areas in Bengkulu Regency, the principle of environmentally sustainable development has not been maximally realized. First, the determination of City Park zoning is carried out unilaterally by the government without coordinating with the community. Secondly, the issue of licensing where the construction of the City Park permit location is unknown to the public. Third, the choice of incentives and disincentives provided by the government is still too small and does not prioritize the interests of the community. Finally, the participation of the community in the construction of the City Park is still very lacking because the government is not transparent regarding the development planning that will be carried out.

Abstract. Recent hydrogeological events have increased both public interest and that of the Scientific Community in a more accurate study of flooding in urban areas. The present project proposes a new model which offers an optimal integration of two models, one for flood wave propagation in riverbeds and the other for flooding in urban areas. We consider it necessary to not only treat the modelling of the outflow in riverbeds and outside riverbeds.together but to integrate them thoroughly. We simulate the propagation in riverbed of the flood event with a model solving the equations of De Saint Venant with the explicit scheme at the finite differences by McCormack. The propagation outside the riverbed is simulated using an algorithm proposed by Braschi et al. (1990). This algorithm is based on a local discretization of the urban territory, divided in a series of "tanks" and "channels". Each tank is associated with an area of an extension related to the position of the other tanks and the quantity of buildings, modelled as insurmountable obstacles. The model facilitates the simultaneous performance of the two simulations: at each instant, the quantitiy of water overflow, depending on the piezometric level in every section, is calculated as a function of the dimensions of the weirs (the banks), assuming it passes through the critical state. Then, it is transferred to the tanks placed in the surroundings of the overflow points. Those points are the starting nodes for the propagation of the flood because they are connected to the network of tanks in which the surrounding land has been schematised. In this paper, we present a comparison of one of the most powerful models of inundation simulation in urban and no-urban areas. The field area is the city of Albenga (SV, Italy) and the simulated event is the inundation of the 1994 (return period of about 25 years).

Problemas e catástrofes geradas por ações da natureza são cíclicos na história de nosso planeta.Um desses problemas, se não o principal e mais recorrente, são as inundações que vêm ocasionando diversos prejuízos tanto para a população quanto para os municípios em geral. Com o município de Itajubá-MG não é diferente. Principalmente por ter se desenvolvido às margens do rio Sapucaí, tem passado por problemas com inundações desde a sua fundação em 1819. No ano 2000, foi registrada uma das suas maiores inundações, que afetou 80% da sua população urbana. Atualmente, devido aos avanços da tecnologia, problemas referentes às inundações podem ser diagnosticados e evitados, utilizando-se programas computacionais, como Autocad e Global Mapper, com os quais, dentro deste trabalho, pôde-se se ter a real noção das áreas dentro do município em estudo susceptíveis a enchentes e inundações. Como principal resultado, observou-se uma mancha de inundação ocupando 65% da área urbana total do município, o que pode servir como base para realizar obras de prevenção e permitir um avanço municipal controlado. A partir desse levantamento pode-se ter a representação da fragilidade da cidade quanto a problemas ambientais decorrentes das chuvas torrenciais. Percebe-se a necessidade de um maior e melhor planejamento do crescimento urbano, por parte dos órgãos regulamentadores, adotando-se estratégias para o desenvolvimento eficiente e sustentável da região. Palavras-chave: Inundações. Planejamento. Problemas.   Flood spots in municipality of Itajubá-mg Abstract Problems and disasters generated by nature actions are cyclical in the history of our planet. One of these problems , maybe the major and most frequent, are the flooding which has been causing many losses for both the population and the municipalities in general. In the city of Itajubá -MG it is not different. Mainly because the city is located in the banks of the Sapucai river, it has experienced problems with flooding since its foundation in 1819. In 2000, the city faced one of its biggest floods, which affected 80% of its urban population. Currently, due to advances in technology, problems related to flooding can be diagnosed and prevented by using computer programs such as Autocad and Global Mapper, which ones, in this work, allow us to have a good idea about areas in the studied city, that could be potentially affected by floods. As the best result,  one flood spot occupying 65% of the urban area of the city was observed. The information can be used for preventing actions and as a base for a mediated growing. From this results, it is possible to measure how fragile is the city regarding to environmental problems related to storms, which requires that regulatory organizations make a bigger and better growing planning for the urban areas, applying strategies for the efficient and sustainable development in the region.

In the face of new global challenges, the economic and social significance of territorial problems in the Russian Federation has received a different, extremely acute meaning. The crisis and shortage of the budgets of most of the municipal formations in the country predetermine the shift of problems of ensuring sustainable development of urban areas from theory to practice. The purpose of this study is to develop a methodology for determination of the priority directions for the city's industrial development. The paper analyzes the principles of sustainable development in the field of urban planning and spatial planning, outlines the mechanisms for stimulating economic growth in cities and the ways to determine the priority directions of the city's industrial development. The authors carried out a practical testing of the proposed methodology on the example of the city of Penza. Recommendations for a more complete use of the potential of the machine-building industry are developed.

Hailed as the “foundation of the next industrial revolution,” nanotechnology is reshaping the landscape of technological innovation and creating hope around the world. Some believe that nanotechnology can address the critical needs of developing countries, but others are less optimistic. At one end of the spectrum, scientists predict that, among other accomplishments, nanotechnology can alleviate poverty, provide safe drinking water, and cure diseases. At the other end, skeptics warn that nanotechnology can further widen the gap between the rich and the poor, contributing to an already imbalanced global landscape. What can nanotechnology bring to the 21st century? How and in what ways should it intersect with law, public policy, and the plight of the developing world?This article argues that the international community can harness nanotechnology to create sustainable development, particularly in the field of water remediation and treatment, but it must learn from its past missteps and adopt a strategy that combines two competing theories: instrumentalism and contextualism. Instrumentalism is the concept that technology is superb and stakeholders can easily transfer it from one application to another. In contrast, contextualism places technology in a socioeconomic context and conditions technological success on the stakeholders’ ability to meet local needs.

Abstract Most of the rehabilitations of river sections with their banks in cities has often been inappropriate. The reason for this is that designers do not understand the natural functioning of a river and they are synthesizing and sterilizing these urban spaces, distorting its natural functioning. Besides, there are clear proofs that these rehabilitations are useless, contributing to the devaluation of the river ecosystem without improving its relationships with the city. The other effect of the water lines destructions are the educational terms, broadcasting a wrong idea of the functioning of the river. This article tries to show briefly, how a river works, what arethe natural characteristicswhich should be valued by a rehabilitation and what has gone wrong in recent rehabilitation works. Using the theoretical drawings, based on examples from real life, and supported by photographs, the authors present also the possible negative consequences of the urban mistakes for the sake of operating of cities. The paper shows some techniques of natural engineering, using natural materials and vegetation that may be employed. This may become a green intervention, making these techniques much more economic and educational, improving life quality thanks to public access to attractive parks and squares by rivers.
