Abstract This article presented the results of a comparative analysis of carabid species compositions (Coleoptera: Carabidae) in urban green areas of the City of Lublin, Eastern Poland. In this study, the occurrence and abundance of ground beetles were analysed according to habitat preference and dispersal ability. A total of 65 carabid species were found in the three green areas. Obviously, the high species richness of ground beetles in the greenery of the Lublin is determined by the mostly undeveloped floodplain of the river Bystrzyca. The species richness of carabids and their relative abundance decrease in the assemblage of green areas under the effect of isolation of green patches and fragmentation of the semi-natural landscape elements in the urban environment. Generalists and open-habitat species significantly prevailed in all green areas. The prevailing of riparian and forest species at floodplain sites of the river Bystrzyca demonstrated the existence of a connection of the carabid assemblage with landscape of river valley. The Saski Park and gully “Rury” are more influenced by urbanization (fragmentation, isolation of green patches) and recreation that is consistent with the significant prevalence of open-habitats species in the carabid beetle assemblage.

<p>The smart and sustainable city idea gained momentum in recent years in order to cope with population growth in urban areas and to make the city live. Cities are projected to consume 70% of the world's resources and 66% of the world population by 2050. Most of tier-3 and tier-2 cities will convert to tier-1 city, and we need to identify and protect the urban green spaces. Urban green areas have many esthetic advantages, including environmental benefits such as a fall in city temperature in the summer and absorption of rainwater. Social advantages are such as feelings of happiness and peace. Objective quantification of greenery on its neighbourhood spatial distribution may help identify essential and potential areas. Heterogeneous land uses describe urban areas. Urban heat island (UHI), with high Land surface temperatures (LST), is distinguished by its city development pattern, socioeconomic and anthropogenic activities. The LST is rising rapidly not only in cities but also in tier-3 & tier-2 cities.  Urban green areas, including parks, playgrounds, gardens and areas, such as ponds, pools, lakes and rivers, will contribute to the control of land temperatures in and around the city. Such spaces also lead to the formation of the Urban Cooling Island (UCI), where temperatures are comparatively cooler than surrounding temperatures, because of their shade of the trees and their evapotranspiration. This cooling island formation is referred to as the Park Cooling Island (PCI) impact. The present work aims to describe the effect of urban green and urban blue spaces on LST using a range of data sources with geospatial technologies. Udupi town, which comes under Udupi district, Karnataka, India is a tier-3 city, selected for the present research work. The data used in the study include Landsat 8 temporal satellite images and secondary data, such as field data from various government and semi-government organisations. LST has been measured using the emissivity reference channel algorithm from Landsat 8 thermal bands. Different indices such as Normalized Difference Built-up Index (NDBI), Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index NDWI, Land Shape Index (LSI) are determined from images from Landsat 8. The results show that LST exists with high spatial variability and urban green, blue spaces have a stronger influence on LST.</p>

A existência de áreas verdes dentro da área urbana influencia diretamente na melhoria das condições ambientais e sociais. Partindo desse pressuposto, as discussões aqui expostas visam classificar as praças como áreas verdes ou espaços públicos, baseados em suas funções apresentadas, tais como, função ecológica, estética, lazer e área permeável de 70%. Assim sendo, tendo como foco principal a cidade de Montes Claros, o presente trabalho busca aplicar os conceitos, métodos e técnicas que auxiliem na identificação, classificação, quantificação e mapeamento das praças da cidade, definindo as mesmas como área verde ou espaço livre. A metodologia utilizada na delimitação e classificação das praças baseou-se na revisão da literatura e na utilização de imagens de satélite com alta resolução espacial, assim também como trabalhos de campo. Constatou-se que as praças consideradas como áreas verdes estão dispostas de forma heterogênea na cidade, ocupando desde loteamentos com condições mais precárias até locais mais dinâmicos e estruturados, observando que ainda existem alguns locais que não dispõem dessas áreas. Conclui-se que, a cidade de Montes Claros possui cerca de noventa e seis praças, destas, oitenta e uma foram classificadas como espaços livres devido apresentarem parte ou nenhuma das funções para ser designada como área verde e dezesseis foram consideradas como áreas verdes por apresentarem todas as funções.

Abstract The article presents the analysis of roundabouts design aspects including the location of underground and overground infrastructure. Authors also undertake an attempt to assess the existing situation with planning conditions. Many differences depended on the roundabout size, location, surroundings, natural conditions, landform technology used were noted. Roundabouts design should include both the natural arrangements and art installations, increasing the area of urban green areas in parallel using the area as a place for works of art exposure. For Zielona Góra urban area this is of particular importance because of the multitude of roundabouts and their good position in the city structure.

Abstract: the work presents reflective elements on the changes of the space in the green areas of the city of Nampula due to the trade. He argues that urban green areas built for ecological, aesthetic and even psychic functions, socially produced, become places of exacerbated consumption and, at the same time, the medium of formal and informal commerce. The objective is to analyze the (re) production of the space of the urban green areas in Nampula city, as well as the practice of informal commerce, in order to perceive its spatial dynamics. In order to do so, an analysis was carried out from a review of the bibliography in order to understand the conceptual meaning and later, to analyze the trade dynamics practiced in these areas, the spatiality that it reproduces. The results indicate that the green areas of the city have turned into places of practice of formal commerce carried out in stalls and fixed stalls subject to the payment of taxes and the informal practice practiced by mobile strollers who evade taxes.A Reprodução do Espaço nas Áreas Verdes Urbanas na Cidade de Nampula, MoçambiqueResumo: o trabalho apresenta elementos reflexivos sobre as alterações do espaço nas áreas verdes da cidade de Nampula em função do comércio. Argumenta como as áreas verdes urbanas construídas para funções ecológicas, estéticas e até psíquicas, socialmente produzidas passam a ser locais de consumo exacerbado e ao mesmo tempo o meio onde se realiza o comércio formal e informal. O objetivo é analisar a (re) produção do espaço das áreas verdes urbana da cidade de Nampula, bem como a prática comércio informal, de modo a perceber a sua dinâmica espacial. Para tanto, realizou-se uma análise a partir de revisão da bibliografia de modo a compreender a acepção conceitual e a posterior, analisar a dinâmica do comércio praticado nestas áreas e a espacialidade que ela reproduz. Os resultados indicam que as áreas verdes da cidade, transformaram-se em locais de prática de comércio formal realizado em bancas e barracas fixas sujeita ao pagamento de impostos e o informal praticado pelos vendedores ambulantes de bancas móveis que se evadem dos impostos.La Reproducción del Espacio en las Areas Verdes Urbanas de la Ciudad de Nampula, MozambiqueResumen: los elementos reflejados en las alteraciones de las espaciosas áreas verdes de la ciudad de Nampula son analizadas en este trabajo, en función de la actividad comercial desarrollada en estas. Argumentando como estas áreas verdes urbanas construidas con finalidades ecológicas, estéticas e incluso psicológicas para la sociedad, se convierten en locales de consumo exacerbado y al mismo tiempo, en el medio en donde se realizan actividades de comercio informal pero de naturaleza formal. El objetivo es analizar la (re) producción del espacio de las áreas verdes urbanas de la ciudad de Nampula, así como la práctica comercio informal, como para percibir su dinámica espacial. Realizando un análisis a partir de revisiones bibliográficas, para comprender el significado conceptual, y posteriormente analizar la dinámica comercial practicada en estas áreas, partiendo de cómo se da esta espacialidad. Los resultados indican, que las áreas verdes de la ciudad, se transformaron en locales en donde se desarrolla el comercio, siendo practicado en puesto fijos sujetos al pago de obligaciones fiscales el formales y el informal, ejercida por vendedores ambulantes de quioscos que se evitan de los impuestos.
