Abstract : The importance of research has emerged by focusing on sustainable green zone planning to solve the problem of degradation through sustainable strategies, to make green areas determine buildings, not the other way around using GIS, by working on a hypothesis (green areas planning according to an appropriate strategy can sustain cities). The principle of urban planning, urban sustainability, sustainable planning and sustainable cities, as well as urban sustainability and many strategies that support green zone planning and rely on a number of factors for sustainable cities, have been addressed. The research was based on how to plan green areas sustainably, what constraints the planners face in the Dora area south of Baghdad, and the reasons for their deterioration in the urban environment, and after analysing and comparing the changes that occurred over three periods of time (2004 and 2009 and 2019) for 10 residential stores to assess the state of the green areas during that period and how they changed, what problems led to the reduction of areas, increased areas built at their expense, compared to the standards of urban and rural housing in Iraq and the basic plan of the company Paul Servis in 1971, Sustainable planning thus creates a balance in the environment, economy and social values so that these new places meet the work and life needs of the local population and their interests, as one of the indicators of sustainable cities environmental, social and economic, measured by the availability of green and preserved areas relative to population density and coverage, which are one of the most important components of the blocs of urban areas to continue the quality of urban life and environmental and social sustainability, and the ratio of green areas to areas built in a sample of the shop Housing in the study area is very few in most stores and is not in line with international standards, so the current standards need to be adjusted and increased from what they are now, as well as laws in general need to be updated because they are in their current state to achieve the sustainability of green areas in the study area. The most important proposals and solutions that address the problems of green areas (developing a specific strategy, developing some laws on the protection of green areas and setting environmental performance standards for green areas). The research recommended the need to review the planning standard for the individual’s share of green spaces as it does not correspond to the increase in population density, and to guide the pursuit of sustainable strategies within the plans prepared by the long-term municipal departments supporting green areas and work to support environmental performance within municipal circles by presenting the award for outstanding environmental performance on conservation capacity and increasing green spaces, urging a focus on the sustainability of Iraqi cities as they suffer from increased desertification and dredging of green areas and current climate change.

In this article, urban allotment gardens (UAGs) are discussed as one of the alternative urban development frameworks - Slow City. The UAG concept as well as the Slow City agenda aims to protect and enhance strong community relationships, decision making, civil engagement, group learning, and leisure practices for people of all ages in close proximity to green spaces. The authors argue that the statutory aims, organizational culture, and governance rules of UAGs are largely coherent with the formal Slow City agenda. The authors analyze the threats to sustainable cities and the alternative urban development agendas in the context of Polish allotment gardens. With increasing problems of soil pollution, abandoned gardens, informal housing, and limitation of access to the green areas of the UAGs for other inhabitants, the pressure to reduce the number of UAGs is reinforced.

Green Areas

Urban green areas present a lucid example for the harmonious co-existence of the artificial and natural environments best illustrated by their interdependence and interconnection in urban spaces. Urban green areas are essential for the health and wellbeing of citizens. The present study aimed to investigate those multiple benefits for citizens that arise through the existence of urban green areas, as well as important policy dimensions that should be considered when designing the expansion of urban green spaces in urban development. The study was based on a literature review to examine for available evidence on the benefit levels derived by the existence of urban green areas. An extended literature review was followed by a structured review, based on specific inclusion and exclusion criteria, which partly followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The search was conducted in two databases, and a total of 1674 articles and abstracts were identified through the database searches. After removing 114 duplicates, 1560 records were initially screened based on title and abstract. Following inclusion and exclusion criteria, 14 articles were incorporated in the structured review and a total of 47 in the extended review. The extended literature review identified 33 additional articles examining aspects of benefits that did not fall under the pre-established inclusion and exclusion criteria used in the structured review, such as health benefits and other social parameters associated with urban green spaces. The selected studies were allocated in five principal groups according to study types: three of the them consisted of studies employing “willingness to pay” (WTP) methods, five were based on property values, two studies assigned monetary values, while another two assigned CO2 values, and, finally, two studies were based on qualitative criteria. The results indicated benefits to citizens and increased welfare levels gained by the existence of urban green areas. The conducted review revealed a number of findings and recommendations that could direct future research and urban policy. Those hints could assist local authorities as well as stakeholders in order to measure and assess the benefits of green spaces and urban parks and promote measures and programs to assist their further deployment.

Abstract Background Childhood obesity is an important public health issue worldwide and includes different risk factors, such as environmental pollutants exposure or physical activity. Neighborhood composition and green spaces availability could contrast obesogenic lifestyles and promote healthy habits, whereas, urbanization and traffic volume exposure are inversely associated with physical activity and worsen effects on childhood health. Methods This project analyzed students involved in the HBSC survey from the Piedmont Region. Data were collected in 2018, following the protocol. All the subjects were georeferenced within buffers around schools. Green-spaces availability was measured by Normalised Difference Vegetation Index (NDVI-satellite images) while urbanization was calculated by population density, traffic intensity (satellite measurements) and air pollution concentration (sampling stations). Results Overall, the sample included 3022 subjects, with amount 50% male/female and 30% for each age group (11-13-15 years old). Concerning weight status, above 14% of the all sample is obese or overweight, with, respectively, 20% among boys and 11% among girls. Preliminary analyses showed an association between weight status and population density (rural vs urbanized areas). Currently, we are analyzing the association with greenness and the other measures of urbanization. Conclusions Our preliminary findings suggest that high urbanization levels impact health implementing weight in children. We are testing the hypothesis that greenness positively influences weight status and reduce negative effects of urbanization and air pollution. The managing of these risk factors must be deepened and corroborated by active preventive Public Health strategies for improving children health. Key messages Urbanization and greenness may influence weight status in children. Public Health strategies must be improved for children health.

Establishing reference conditions in rivers is important to understand environmental change and protect ecosystem integrity. Ranked third globally for fish biodiversity, the Mekong River has the world’s largest inland fishery providing livelihoods, food security, and protein to the local population. It is therefore of paramount importance to maintain the water quality and biotic integrity of this ecosystem. We analyzed land use impacts on water quality constituents (TSS, TN, TP, DO, NO3−, NH4+, PO43−) in the Lower Mekong Basin. We then used a best-model regression approach with anthropogenic land-use as independent variables and water quality parameters as the dependent variables, to define reference conditions in the absence of human activities (corresponding to the intercept value). From 2000–2017, the population and the percentage of crop, rice, and plantation land cover increased, while there was a decrease in upland forest and flooded forest. Agriculture, urbanization, and population density were associated with decreasing water quality health in the Lower Mekong Basin. In several sites, Thailand and Laos had higher TN, NO3−, and NH4+ concentrations compared to reference conditions, while Cambodia had higher TP values than reference conditions, showing water quality degradation. TSS was higher than reference conditions in the dry season in Cambodia, but was lower than reference values in the wet season in Thailand and Laos. This study shows how deforestation from agriculture conversion and increasing urbanization pressure causes water quality decline in the Lower Mekong Basin, and provides a first characterization of reference water quality conditions for the Lower Mekong River and its tributaries.

The article discusses the interface between the influence of the urban climate and the traffic accident, there are as reference the results of the research carried out for the Araraquara case, SP, Brazil. Initially presented a brief analysis of urban mobility, geoprocessing (GIS) and the climatic importance in relation to urban sustainability. The article analyzes the urban climate of Araraquara, especially with regard to solar radiation on city streets and green areas. It was based on the premise that there is a correlation between the urban microclimates and the variables related to the traffic accident. Thus, a georeferenced mapping of the urban geometry was carried out by associating the climatic variables such as solar radiation, temperature and humidity of the air, to three parameters related to the traffic accident were chosen from the a) traffic accident with victim, b) without victim and c) motorcycle. At the end, the article proposes how the results found can reduce traffic accident and contribute to urban planning

O artigo propõe uma discussão teórica acerca das paisagens coexistenciais interespecíficas na urbe, voltando-se especialmente à morada humana. Esta é percebida como o lugar da convivência entre humanos e não-humanos – também se considera o seu entorno, onde aparecem os quintais/pomares e os espaços verdes habitados pela fauna silvestre urbana. A coexistência interespecífica contribui para a diversidade na conformação das paisagens citadinas, sendo que as ambiências domésticas – a localidade do espaço habitado/lócus da experiência íntima – permitem a humanos e não-humanos o compartilhamento de uma vida juntos a partir de diferentes formas de interações simbólico-práticas. As áreas verdes revelam-se lugares de interações interespecíficas diversas na urbe, figurando enquanto espaços de contato. Para as reflexões que proponho realizar, parto de minha experiência de coabitação com gatos domésticos e de meu ofício de etnógrafo que pesquisa as relações entre humanos e não-humanos em uma área verde na cidade de Belém (PA) na Amazônia.Palavras-chave: Paisagens. Cidade. Habitat. Animais. Áreas verdes. Interespécies.The Coexistent and Interspecific Landscapes or About Humans and Nonhumans Sharing Domestics Places in an Amazonian City  AbstractThe paper proposes a theoretical discussion about the coexistent and interspecific landscapes at the urbis, regarding, specially, the human shelter. This is perceived as a place of coexistence between humans and nonhumans – its surroundings where there are yards/orchards and green spaces inhabited by urban wildlife is also considered. The interspecific coexistence contributes to the diversity in shaping cityscapes and the domestic ambiences - the location of the living space/locus of intimate experience - allow human and nonhuman sharing a life together, founded on different forms of symbolic and practical interactions. The green areas turn up in places of diverse and interspecific interactions at the urbis, constituting spaces of contact. Aiming at these reflections, I consider my own coexistence experience with domestic cats and my work as an ethnographer who studies the relationships between human and nonhumans in a green area in the city of Belém (PA) in Amazon.Key words: Landscapes.

Life Cycle Analysis (LCA) is a procedure used as an analytical tool for the evaluation of the environmental impact caused by a material, a manufacturing process or product. For an end product, LCA requires both the identification and quantification of materials and energy used in all stages of the product’s life, together with their environmental impact. It requires therefore a huge amount of data about materials, components, manufacturing processes, energy consumption and the relevant environmental impacts. For this reason, a number of software and databases have been developed, in order to facilitate LCA users. These are the so-called Eco-Tools, used in an effort to minimize the environmental impact of a product from the materials and the energy used for production. In this paper, LCA is conducted for solar thermosyphonic systems, with the aid of three commercially available Eco-Tools, usually used by LCA practitioners, namely: Eco-It, GEMIS and SimaPro, and the results are compared. Although all three tools claim accordance with the international standards and guidelines, differences do exist. A typical solar thermosyphonic system (DSHWS) with a 4 m2 collector area and a capacity of 150 dm3 that covers the hot water needs of a three person family in Thessaloniki is used as case study. The results of the three tools are compared for each component of the solar system as well as for each material used and for the conventional energy substituted by the system.

Cultural Role

One of the criteria for a comfortable ecologically clean urban environment is access to green spaces, their number and quality in any given city. Public green spaces play an important socio-cultural role in the context of active and passive recreation of citizens, various types of recreational activities. The relevance of this study is due to increased attention to the formation of open public spaces in the city of Krasnoyarsk. The purpose of this work is to trace the evolution and identify the social and cultural significance of the green public spaces in Krasnoyarsk. The objectives of the research are to study the green spaces of Krasnoyarsk in a historical retrospective, analyze the green spaces of Krasnoyarsk from the point of view of their ecological significance, recreational use. Research methods included literature review on the topic, analysis of historical data, field survey of the territory, long-term observation, photographic recording, comparative retrospective analysis, and graphic-analytical method. The study captures the most common types of public green spaces and their role in creating a comfortable urban environment. It traces in the most detail the evolution and cultural significance of the most important historical green spaces in Krasnoyarsk: the City Garden (now the Central Park), Yudinsky Garden, Krutovsky Garden. These examples show that gardens and parks can be formed both on the basis of the natural environment of urban forests, and artificially created by the efforts of citizens, that over time they can undergo various quantitative and qualitative, planning and functional transformations. Despite the transformations that have taken place, all the studied historical objects still exist and are used for their intended purpose. In addition to these historical green areas, we examine the newly organized public green spaces with a cultural and recreational component over the past decades: Tatyshev Park, All-season Fun-Park Bobrovy Log, Flora and Fauna Park Roev Ruchey, Dream Gardens and others. The article notes the importance of municipal, public and private initiatives in the organization of local green areas. The analysis allows us to assert that there is a certain system of public green spaces in Krasnoyarsk. It has disadvantages, such as an uneven distribution of green areas throughout the city, lack of interconnections between individual elements, aging of certain areas of greenery, and the complete destruction of some. Nevertheless, the city authorities, architects, designers and the general public make great effort to create a green framework for Krasnoyarsk destined to have an important recreational and cultural role.
