Today, the prevention and the risk management occupy an important part of public policy activities and are considered as major components in the process of sustainable development of territories. Due to the expansion of IT processes, in particular the geomatics sciences, decision-makers are increasingly requesting for digital tools before, during and after the risks of natural disasters. Both, the geographic information system (GIS) and the remote sensing are considered as geospatial and fundamental tools which help to understand the evolution of risks, to analyze their temporality and to make the right decisions. <br><br> The historic events (on 1996, 2002 and 2010) which struck the city of Mohammedia and having caused the consequent damage to vital infrastructure and private property, require a thorough and rational analyze to benefit from it and well manage the floods phenomena. This article present i) the contribution of the geospatial tools for the floods simulation of Oued of el Maleh city at various return periods. These tools allow the demarcation of flood-risk areas and so to make floods simulations in several scenarios (decadal flood, 20-year flood, 50-year flood, 100-year flood, 500-year flood &amp; also millennial flood) and besides (ii) present a synthesis map combining the territorial stakes superposed on the flood scenarios at different periods of return.

The article deals with the implementation of the complex of political and socio-economic measures of the Soviet state, called the policy of “war communism” in the cities of the Steppes and Turkestan in 1918-1921. Based on materials gleaned from various sources, the author endeavours to explore the processes of socialization and municipalization of private houses and dwellings, the nationalization of private property, which took place in the cities of the KazASSR and tassr; highlight some of the issues related to the subject policy of “war communism” in the cities of Kazakhstan. Various restrictive decrees and orders of the Soviet power in this period, aimed at limiting commodity-money relations and the prohibition of the right to private property put people into a rigid framework of survival. Approved in the sphere of public life, the ideology of “war communism” inevitably left its mark on the life of the city. This ideology was a special sociocultural phenomenon, strengthening other social psychology and ethics which propagandized the need to destroy the old “bourgeois” culture and create a new “proletarian culture”. “War Communism” as opposed to “bourgeois individualism” principles of the socialist community, broske vital foundations of society. A characteristic feature of this period is the legitimization of violence and its use as a universal remedy of solving all problems. Under the pressure of revolutionary changes the sense of justice in society underwent considerable transformation. The right to inviolability of private property was completely ignored. The ruling regime no longer recognized the existing legal mechanisms, replacing them with the amorphous concept of “revolutionary legality.”

The purpose of this study was to analyze guerrilla gardening’s relationship to urban space and contemporary notions of sustainability. To achieve this two case studies of urban agriculture, one of guerrilla gardening and one of community gardening were developed. Through this comparison, guerrilla gardening was framed as a method of spatial intervention, drawing in notions of spatial justice and the right to the city as initially theorized by Henri Lefebvre. The guerrilla gardening case study focuses on Dig Kingston, a project started by the researcher in June of 2010, and the community gardening case study will use the Oak Street Garden, the longest standing community garden in Kingston. The community gardening case study used content analysis and semi-structured long format interviews with relevant actors. The guerrilla gardening case study consisted primarily of action based research as well as content analysis and semi-structured long format interviews. By contributing to the small, but growing, number of accounts and research on guerrilla gardening this study can be used as a starting point to look into other forms of spatial intervention and how they relate to urban space and social relations. Furthermore, through the discussion of guerrilla gardening in an academic manner more legitimacy and weight will be given to it as a method of urban agriculture and interventionist tactic. On a wider scale, perhaps it could even contribute to answering the question of how we (as a society) can transform our cities and reengage in urban space.

This paper presents an English case of urban agriculture, the Edible Public Space Project in Leeds, contextualised in a context of urban agriculture initiatives committed to social-environmental justice, to the reproduction of common goods and the promotion of an urban planning which promotes the right to food and to the construction of urban space from the bottom up. The case study emerged as the result of action-research at the crossroads between urban planning policies, community work and critical geography. As opposed to many similar initiatives, the Edible Public Space Project is not intended merely as a temporary initiative hidden within the tiny folds of the city, but rather as an experiment which imagines and implements alternatives to current forms of urban planning within those folds and it contextualises them in the light of the ecological, fi nancial and social crisis of the last decade.

This article aims to discuss the determinants of digital active citizenship behaviors such as the e-participation using reporting urban apps. The article makes a comparative analysis between two groups of citizens: a) 98 users of a reporting app (MyHomeCity) who were selected for the case study); and b) 148 non-users of reporting apps. Users of MyHomeCity revealed higher scores for the satisfaction for life in the city, self-esteem, self-efficacy, and perceived happiness, for all place attachment dimensions and all digital citizenship dimensions except for political activism (online and offline) and critical perspective. The probability of being an app user is predicted by satisfaction for living in the city, place identity (attachment), and digital citizenship dimensions. The implications for public decision makers, app developers, and citizens' organizations are discussed.

Hydropower represents an interesting technology: affordable, renewable, and flexible. However, it must cope with climate changes and new energy policies that jeopardize its future. A smooth transition to sustainability requires decision makers to assess the future perspectives of hydropower: about its future revenue and related uncertainty. This investigation requires a multidisciplinary approach as both streamflow and energy mix will evolve. We simulated future streamflow based on eight climate scenarios using a semi-distributed hydrological model for our case study, the Tremorgio hydropower plant located in southern Switzerland. Next, using a hydropower management model we generated income according to these streamflows and twenty-eight electricity price scenarios. Our results indicate that climate change will modify the seasonality of inflows and volumes exploitable for hydropower generation. However, adaptive strategies in the management of reservoirs could minimize revenue losses/maximize revenue gains. In addition, most market scenarios project an increase in revenues, except in the case of high wind and solar energy penetration. Markets do not provide the right incentive, since the deployment of intermittent energy would benefit from more flexible hydropower.

This article uses Lefebvre’s spatial triad and his concept of The Right to the City to categorise open-world video games as contested virtual spatial experiences, interconnected with the non-virtual spaces in which they are produced and played and replete with the same spatial, capital forces of alienation to be negotiated and maintained. We use qualitative gameplay data ( n = 15), unpacking players’ journeys through Lefebvre’s conceived, lived and perceived spaces, to show, respectively, how open-world games can be (1) fundamentally about space, (2) spaces interconnected with the non-virtual world and (3) disruptive spatial experiences. In utilising The Right to the Virtual City and our players’ tendency to retreat into the wild spaces of our case study game, Red Dead Redemption 2, we evoke the same alienating forces of commodification and capitalism to which Lefebvre spoke, positioning open-world video games as both contested spatial experiences and opportunities to challenge spatialised inequalities.

Beirut is a car-dependent city, with 80% of Beirut citizens using their private cars to move across the city (the rate of car ownership is higher than regional and global benchmarks: 627 cars/1000 in Beirut, 550/1000 in Dubai and 170/1000 in Singapore). This reality causes two related impacts: an increased parking demand and decreased public transportation usage. Furthermore, in order to discuss these aspects, our study addresses the following question: How can the municipality’s interventions and mobility system reforms, such as smart public transportation systems and shareable mobility, reduce parking demand? As our methodology, it consists of three sections: (1) determine Beirut's parking problems by estimating parking demand and supply; (2) assess the potential effects of Beirut municipality policies in comparison to international experiences; and (3) evaluate the potential impacts of the smart public transportation system and shareable mobility in reducing parking demand. This paper studies parking growth in developing countries, such as Lebanon, and can help planners, decision-makers, and the Beirut municipality to make more informed decisions about parking policies, and to meet growing parking demand by introducing smart interventions that have high local potentials.

During 2020, the COVID-19 crisis expanded the use of digital tools in public health and social care. The aim of this qualitative, single-case study was to scrutinize how homecare professionals experienced meaningfulness in their work in the midst of a crisis and with the utilization of the videophone in long-term homecare service provision. The empirical data consisted of 20 thematic interviews carried out among homecare professionals and their managers in the city of Tampere, Finland. The results indicated that the videophone can generate significance, self-realization and broader purposes among homecare professionals, thus providing meaningfulness for work in the midst of a crisis and continuous work-related changes. In addition, a crisis may support change in the meaningfulness of e-welfare in work-related tasks and aid in overcoming reluctance amongst public-sector social care (homecare) professionals towards an e-welfare initiative: the videophone (VideoVisit).

ResumoEste trabalho visa demonstrar o processo de redemocratização da cidade, tendo em vista que o Brasil enquanto Estado democrático de Direito, necessita dos instrumentos de participação social, capazes de conferir ao cidadão o sentimento de pertencimento e de apropriação do espaço urbano. Utilizou-se como metodologia a revisão bibliográfica para construção do primeiro e segundo capítulo, enquanto o terceiro capítulo foi construído através do estudo de caso do Projeto MobCidades no Município de Ilhéus-BA. Como resultado, constatou-se que a mobilização dos atores sociais e os mecanismos de democracia participativa ganham relevância no cenário político, mostrando-se imprescindíveis para viabilizar a destinação de recursos públicos para ações e projetos que atendam aos interesses de diversos segmentos sociais e propiciem melhorias significativas no âmbito da acessibilidade e da mobilidade urbana. Apesar da legitimação da participação popular nas questões urbanas, percebe-se que poderes deliberativos ainda permanecem sobre o manto da máquina estatal, enquanto o cidadão encontra-se distante da gestão pública, o que nos faz questionar sobre o funcionamento dos mecanismos de participação social, visando incluir os anseios da população nas decisões referentes a políticas de mobilidade.Palavras-chave: Redemocratização da cidade. Participação social. Inclusão. AbstractThis work aims to demonstrate the process of redemocratization of the city, considering that Brazil as a democratic State of Law, needs the instruments of social participation, capable of giving the citizen the feeling of belonging and appropriation of the urban space. To this end, a case study of the MobCidades Project was carried out in the Municipality of Ilhéus-BA, based on information and data obtained from the Instituto Nossa Ilhéus proponent of the project and a bibliographic review, based on books, periodicals and legislation dealing with on the matter, and case study. As a result, it was found that the mobilization of social actors and the mechanisms of participatory democracy gain relevance in the political scenario, proving to be essential to enable the allocation of public resources for actions and projects that meet the interests of different social segments and provide improvements significant in the scope of accessibility and urban mobility. Despite the legitimacy of popular participation in urban issues, it is clear that deliberative powers still remain under the mantle of the state machine, while the citizen is distant from public management, which makes us question the functioning of the mechanisms of social participation, aiming to include the population's concerns in decisions regarding mobility policies.Keywords: Redemocratization of the city. social participation. Inclusion.
