<p><strong>Resumo: </strong>O processo de crescimento desordenado e sem planejamento das cidades trouxe consequências desastrosas sobre o espaço urbano e a qualidade de vida da população, além de provocar profundas modificações no meio ambiente, contribuindo para geração de áreas vulneráveis. Dessa forma, o trabalho teve como objetivo avaliar o uso e ocupação do solo no meio urbano quanto a geração de riscos, adotando-se o munícipio de Catolé do Rocha-PB, como estudo de caso. Dentre os procedimentos metodológicos, partiu-se de revisão bibliográfica, consulta documental a fontes e dados oficiais, emprego de imagens de satélite, com aferição de informações em campo do uso e ocupação do solo, além de dados pluviométricos para avaliação dos territórios de risco. Constatou-se que a expansão urbana foi direcionada para área de manancial, assim como no sentido do Riacho Agon, desmatando parte da mata ciliar, contribuindo para a construção do risco. Tais problemas socioambientais só serão solucionados por intermédio de conscientização ambiental e adoção de uma política habitacional criteriosa.</p><p align="center"><strong><em>Algebra maps used in determining the irregular occupations and environmental risk in Catolé do Rocha-PB</em></strong></p><p><strong>Abstract</strong><strong>: </strong>The process of uncontrolled and unplanned growth of cities has brought disastrous consequences on the urban space and the population's quality of life, besides causing profound changes in the environment, contributing to generation of vulnerable áreas. Thus, the study aimed to evaluate the use and occupation of land in urban areas as the generation of risk, adopting the municipality of Catolé do Rocha-PB, as a case study.

Intensive urban development has created a shortage of urban green areas. The need to economically plan and use urban green spaces has fueled the redefinition of public spaces and parks so as to provide the residents with both recreation and relaxation facilities, as well as a forum for contact with culture. This paper discusses the case of the Stavros Niarchos Foundation Cultural Center (SNFCC) in the Kallithea district on the outskirts of Athens, near the Mediterranean Sea. It fills a gap in the research on the aspects of the practical functioning of such facilities. The methodology used in the research included an analysis of the literature, the SNFCC’s reports, and an in situ survey. The cultural center hosts a number of events aimed at promoting Greece’s natural and cultural heritage. The paper includes a detailed analysis of the events organized by the SNFCC in the period 2017–2020 and their immense impact on residents. The aim of the study is to show that the creation of the SNFCC with the park areas has functioned as a factor contributing to the improvement of the quality of urban space and the quality of life of the city’s inhabitants. The paper’s conclusions indicate that the sustainable SNFCC project, which fulfils the urban ecology criteria, has been very well received by the visitors—citizens and tourists alike. A program-centered innovation introduced by the SN Park has added great value to their lives. The project contributes to economic and cultural growth, as well as the protection and promotion of heritage.

The modified law of Iranian Administrative divisions has greatly altered the pattern of settlement in recent decades. The promotion of rural areas to urban areas has shifted from mere population standard to combined population-administrative standards. However, all censuses suggest that many rural areas reported as smaller than the minimum population standard have been promoted to urban areas. In the last two decades, this is a clearly prominent phenomenon in the urban system of Iran. This paper evaluates the effects and consequences of promoting small and sparsely populated rural areas to urban areas in the Bushehr province. The used methodology is analytic-descriptive using a questionnaire distributed among 380 members of the target population. Data analysis is conducted in physical, economic, social and urban servicing domains using one-sample T-test and the utility range. The results show that promotion of rural areas to urban areas has positive outcomes such as improved waste disposal system, improved quality of residential buildings, increased monitoring of the construction, increased income, prevented migration and improved health services. However, the results of utility range show that the negative consequences of this policy are more than its positive outcomes, which have been studied in detail.

Providing conditions for health and well-being, especially for those most exposed to social and environmental inequalities, is a precondition for sustainable development. Green infrastructures in peri-urban areas have the potential to improve the quality of life of locals by fostering healthy practices, providing views, or bringing nature closer to the city. This work explores the local perception of well-being within urban green infrastructures (UGI) in the peri-urban fringe of Madrid (Spain) through a combination of qualitative methods: “go-alongs” and “semi-structured static interviews”. The grounded-theory based codification of the data using NVivo software and their subsequent analysis results in the identification of social, natural, and perceptual elements that prove to play a relevant role in locals’ perception of well-being. Among these, connectivity with other green spaces, panoramic views and place-based memories are aspects that seem to make UGI serve the community at its full potential, including perceived physical and psychological well-being. We identify in each case study both positive characteristics of UGI and dysfunctional aspects and areas of opportunity. Lastly, a methodological, geographical, and theoretical discussion is made on the relevance of the case studies and pertinence of the two interview methods as valuable tools for analysis and intervention in the peri-urban landscape.

In recent years, life quality of the urban areas is a growing interest of civil engineering. Environmental quality is essential to display the position of sustainable development and asserts the corresponding countermeasures to the protection of environment. Urban environmental quality involves multidisciplinary parameters and difficulties to be analyzed. The problem is not only complex but also involves many uncertainties, and decision-making on these issues is a challenging problem which contains many parameters and alternatives inherently. Multicriteria decision analysis (MCDA) is a very prepotent technique to solve that sort of problems, and it guides the users confidence by synthesizing that information. Environmental concerns frequently contain spatial information. Spatial multicriteria decision analysis (SMCDA) that includes Geographic Information System (GIS) is efficient to tackle that type of problems. This study has employed some geographic and urbanization parameters to assess the environmental urbanization quality used by those methods. The study area has been described in five categories: very favorable, favorable, moderate, unfavorable, and very unfavorable. The results are momentous to see the current situation, and they could help to mitigate the related concerns. The study proves that the SMCDA descriptions match the environmental quality perception in the city.

O trabalho em questão analisa, segundo o prisma da Geografia, a importância do patrimônio natural em ambiente urbano. Como objetivo principal, pretende compreender a percepção que os residentes na cidade de Coimbra (Portugal) têm da natureza e do papel que o património natural pode desempenhar na qualidade de vida da cidade. Para alcançar esses objetivos, inicia-se o texto com uma reflexão teórica que percorre conceitos como a topofilia e os olhares sociais sobre o ambiente e a natureza em contexto citadino. Depois, seguem-se dois procedimentos diferentes, mas complementares: (1) Como forma de registro da presença e do estado de conservação da natureza em Coimbra e da interação entre os cidadãos e o patrimônio natural naquele espaço geográfico, fez-se uma análise de campo com a montagem de um banco de dados fotográficos que representam excertos deste território; (2) Inquéritos por meio de entrevistas, em dois bairros da cidade – Vale das Flores e Monte Formoso – privilegiando adultos com idades superiores aos 30 anos. Apesar de a pesquisa ter revelado algumas contradições entre a prática e o discurso na percepção e na relação topofílica para com as áreas verdes urbanas, concluiu-se que a presença do patrimônio natural no ambiente urbano ainda se apresenta como uma questão secundária. Contudo, também se verificou que, para reforço desta relação simbólica e/ou funcional, o patrimônio natural deve estar presente em todo o contínuo urbano e não ficar restrito aos bairros mais elitizados ou aos parques. Abstract THE CITIZENS TOPOPHILIA AND THE NATURAL URBAN PATRIMONY: COIMBRA’S CASE STUDY This paper analyzes the importance of natural patrimony in the urban environment, under the prism of geography. The main objective of this study is to understand how nature is perceived in the city of Coimbra (Portugal) and the role that green areas and natural patrimony has in the quality of urban life. To achieve these objectives, this article discusses the conceptual argument about environmental perception, topophilia and the nature in the city. For this, it was used two different procedures: (1) Field analysis on the city of Coimbra with purpose to setting up a photographic database, to verify the presence, conservation and relationship to the natural patrimony inserted in urban environment; (2) Investigation through interviews in two neighborhoods of the city – Vale das Flores and Monte Formoso. The data revealed that the perception and the topophilic relationship to urban green areas are marked by the contradiction between practice and discourse. It was concluded that the presence of natural patrimony in the urban environment still present itself as a secondary issue. Moreover, it was concluded that to strengthen this relationship symbolically and/or functionally the natural patrimony must be present throughout all the continuous urban areas and should not be restricted to elite neighborhoods or parks.
