The recent decades have witnessed a significant increase in the population in peri-urban areas which led to a progressive transformation of peri-urban landscapes, and the reduced ability of agriculture to provide ecosystem services. In order to understand the complex relationships established in peri-urban areas between reference urban centre, urban services (US) and ecosystem services (ES), with particular attention to the landscape, a Discrete Choice Experiment (DCE) was carried out in the transitional peri-urban areas of six municipalities located near the city of Perugia (Italy). The two main goals of this study are analysing the effect of the presence of US and ES on the demand for housing, and exploring the implications in terms of peri-urban land use policy. The results highlight that the availability of some ES can have a significant impact on choice of housing location.

Insectivorous bats provide ecosystem services in agricultural and urban landscapes by consuming arthropods that are considered pests. Bat species inhabiting cities are expected to consume insects associated with urban areas, such as mosquitoes, flying termites, moths, and beetles. We captured insectivorous bats in the Federal District of Brazil and used fecal DNA metabarcoding to investigate the arthropod consumed by five bat species living in colonies in city buildings, and ascertained whether their predation was related to ecosystem services. These insectivorous bat species were found to consume 83 morphospecies of arthropods and among these 41 were identified to species, most of which were agricultural pests. We propose that bats may roost in the city areas and forage in the nearby agricultural fields using their ability to fly over long distances. We also calculated the value of the pest suppression ecosystem service by the bats. By a conservative estimation, bats save US$ 94 per hectare of cornfields, accounting for an annual savings of US$ 390.6 million per harvest in Brazil. Our study confirms that, regardless of their roosting location, bats are essential for providing ecosystem services in the cities, with extensive impacts on crops and elsewhere, in addition to significant savings in the use of pesticides.

In the last few decades European industrial cities have experienced major transformations which have implied the need to rethink the role of nature. Re-naturing the city, reconnecting urban planning and nature and enhancing sustainability, means taking into account ecosystems and biodiversity through a social approach to nature which reconsiders nature as a social product and re-examines city–nature relationships, the way Urban Political Ecology (UPE) suggests. This paper focuses on the Brescia Quarry Park, a suburban space that until just a few years ago was characterized by mining activities. This area has now been transformed into a re-naturalized area and is projected to become one of Europe’s largest re-naturalized protected urban areas. These transformations are signs of a profound change in the urban metabolism. In fact, the community has struggled for many years for the recognition of the value of the area in ecological and cultural terms. Therefore, an approach was adopted based on Urban Political Ecology, which is useful to study how the socio–natural relationships change and how an exploited and degraded land can become a relevant natural area from the local community’s point of view. This approach also allowed us to study conflicts due to unequal power relations and strategies developed by the community to reduce these conflicts. Particular interest was given to the participatory processes which have driven these transformations and to the role played by the different actors involved through top-down and bottom-up approaches. So, we decided to combine UPE and participatory action research—PAR and create a participatory map of the Cultural Ecosystem Services (CES) in the Park. Attention was given to understanding the practices of the stakeholders and benefits for the community. This involvement allowed us to represent the complexity of the re-naturalized urban landscape which was analyzed through the changes in natural, urban and rural features that emerged. During the process, the interaction between citizens and experts was fundamental in co-producing an analysis of the placemaking of urban landscapes and in revealing the socio–ecological interactions of the stakeholders with these places. The results of the mapping process represent a first step towards promoting sustainable environmental planning and management based on the involvement and empowerment of the local population.

"The City of Oslo in Jan Erik Vold’s Poems. The aim of this paper is to examine, from a cultural and social perspective, the Norwegian urban areas and everyday situations in Jan Erik Vold’s (b. 1939) poems. Our close-reading technique reveals important social aspects, different places and streets, located in the capital city of Norway, Oslo. These urban poems written by the contemporary Norwegian poet Jan Erik Vold contribute to the reconstruction of a new Norwegian cultural identity as it is reflected in a selection of poems taken from Mor Godhjertas glade versjon. Ja (Mother Goodhearted’s Happy Version. Yes, 1968), followed by the poet’s wanderings in the city of Oslo in En som het Abel Ek (One Named Abel Ek, 1988), and concluding with his bitter social criticism in Elg (Moose, 1989) and IKKE. Skillingstrykk fra nittitallet (Not: Broadsides from the Nineties, 1993). Vold’s urban poems emphasise the transition from nyenkle (new simple), friendly and descriptive poems which present closely the city of Oslo on foot, to short, political and social critical poems from the 90s. Thus, it is of great importance to traverse various urban ‘landscapes’ in different periods of time, beginning with the 1960s, followed by the 80s and the 90s. Keywords: Jan Erik Vold, urban poems, social criticism, Norwegian urban areas, the city of Oslo "

By integrating social, ecological, and economic perspectives, the assessment of ecosystem services (ES) provides valuable information for better targeting landscape planning and governance. This chapter summarizes different participatory approaches for assessing ES in urban areas of three countries. In Belo Horizonte (Brazil), a conceptual framework for the vacant lots ES assessment is presented as an attempt to integrate landscape, social, and political dimensions. In Leipzig (Germany), a combination of site surveys, interviews, and remote sensing provides a valuable data set that fostered a comparative study between two forms of urban gardening. In Lisbon (Portugal), the study is based on interviews that offer a social insight into the horticultural parks situation, which in turn demands a better dialogue with the municipality. In general, the studies demonstrate the potential benefits of utilizing the ES assessment approaches on urban landscapes, especially for better understanding the interactions between people and nature in urban sites.

IntroductionBirth registration remains limited in most low and middle-income countries. We investigated which characteristics of birth registration facilities might determine caregivers’ decisions to register children in Ethiopia.MethodsWe conducted a discrete choice experiment in randomly selected households in Addis Ababa and the Southern Nations, Nationalities, and People’s Region. We interviewed caregivers of children 0–5 years old. We asked participants to make eight choices between pairs of hypothetical registration facilities. These facilities were characterised by six attributes selected through a literature review and consultations with local stakeholders. Levels of these attributes were assigned at random using a fractional design. We analysed the choice data using mixed logit models that account for heterogeneity in preferences across respondents. We calculated respondents’ willingness to pay to access registration facilities with specific attributes. We analysed all data separately by place of residence (urban vs rural).ResultsSeven hundred and five respondents made 5614 choices. They exhibited preferences for registration facilities that charged lower fees for birth certificates, that required shorter waiting time to complete procedures and that were located closer to their residence. Respondents preferred registration facilities that were open on weekends, and where they could complete procedures in a single visit. In urban areas, respondents also favoured registration facilities that remained open for extended hours on weekdays, and where the presence of only one of the parents was required for registration. There was significant heterogeneity between respondents in the utility derived from several attributes of registration facilities. Willingness to pay for access to registration facilities with particular attributes was larger in urban than rural areas.ConclusionIn these regions of Ethiopia, changes to the operating schedule of registration facilities and to application procedures might help improve registration rates. Discrete choice experiments can help orient initiatives aimed at improving birth registration.

The expansion of urban areas and the increase in the number of buildings and urbanization characteristics, such as roads, affect the meteorological environment in urban areas, resulting in weakened pollutant dispersion. First, this paper uses GIS (geographic information system) spatial analysis technology and landscape ecology analysis methods to analyze the dynamic changes in land cover and landscape patterns in Chengdu as a result of urban development. Second, the most appropriate WRF (Weather Research and Forecasting) model parameterization scheme is selected and screened. Land-use data from different development stages in the city are included in the model, and the wind speed and temperature results simulated using new and old land-use data (1980 and 2015) are evaluated and compared. Finally, the results of the numerical simulations by the WRF-Chem air quality model using new and old land-use data are coupled with 0.25° × 0.25°-resolution MEIC (Multi-resolution Emission Inventory for China) emission source data from Tsinghua University. The results of the sensitivity experiments using the WRF-Chem model for the city under different development conditions and during different periods are discussed. The meteorological conditions and pollution sources remained unchanged as the land-use data changed, which revealed the impact of urban land-use changes on the simulation results of PM2.5 atmospheric pollutants. The results show the following. (1) From 1980 to 2015, the land-use changes in Chengdu were obvious, and cultivated land exhibited the greatest changes, followed by forestland. Under the influence of urban land-use dynamics and human activities, both the richness and evenness of the landscape in Chengdu increased. (2) The microphysical scheme WSM3 (WRF Single–Moment 3 class) and land-surface scheme SLAB (5-layer diffusion scheme) were the most suitable for simulating temperatures and wind speeds in the WRF model. The wind speed and temperature simulation results using the 2015 land-use data were better than those using the 1980 land-use data when assessed according to the coincidence index and correlation coefficient. (3) The WRF-Chem simulation results obtained for PM2.5 using the 2015 land-use data were better than those obtained using the 1980 land-use data in terms of the correlation coefficient and standard deviation. The concentration of PM2.5 in urban areas was higher than that in the suburbs, and the concentration of PM2.5 was lower on Longquan Mountain in Chengdu than in the surrounding areas.

Abstract Urban expansion in Latin-American cities is faster than urban planning. In order to implement sustainable planning the capacity of peri-urban areas to provide ecosystem services must be evaluated in the context of competing urbanization and conservation pressures. In this study we analyzed the effect of urban expansion on peri-urban vegetation of the Metropolitan Area of Santiago and what ecosystem services are provided by El Panul, land rich in biodiversity embedded in the fringe of the city. The city has lost vegetation while urbanized areas grow. Under this context, we evaluated the multi-functionality of El Panul through the quantification of three ecosystem services (ES): sense of place through the interviews of 60 residents, recreation via GIS analyses, and local climate regulation determined with air temperature measurements. El Panul increased the provision of urban green spaces, where inhabitants recognize and appreciate ES, and it plays a significant role in mitigating the urban heat island on summer nights. ES have emerged as a concept and framework for evaluating competing urban development alternatives.

Abstract The city is characterized by structure, urban space organization, and specific configurations of the urban fabric. These factors act on distinguishing the city and give it a specific identity with specific features. The urban fabric is different, according to its morphology, planning, and design characteristics. Thus, if we know that the city, affecting and affected by rapid changes in its structure, configuration and space organization, these changes and transformations, according to its topological relations, places and its structure are different in between the city. At the same time, the severity and degree of these impacts also vary from one another location. More areas that resist and hold up against these changes and maintain their structure are the traditional urban areas, usually located in city centers, which retain their identity, authenticity, and urban and physical specificities. The study attempt to find out and diagnose the factors affecting, and then clarify the features, which lead to making the fabric retain its originality, stand up against winds of ongoing changes and transformations that occur in traditional urban fabrics when comparing with other areas in the city. The formation of the urban fabric appears as a result of a balance between internal and external forces, or in other words between more complex relationships, between parts with each other and parts with the whole, acting on its explicit and implicit structure. Implicit structure (genetic system) represents the potentiality, which our study aims to explore its configuration as an objective of the study as well. The research adopted space syntax methodology and its applications to arrive at the traditional know-how, which had weaved the rules of its nature, and also to verify the research hypothesis and achieve its objectives, too. Finally, the study found that the system of relationships that exists between (parts – parts) and (parts – whole), and the nature of these relationships had granted the area its uniqueness to persist against any deformation or rapid transformation over time.

Abstract— The cost of park-recreational, residential, and residential-transport urban landscapes of Moscow has been estimated taking into account land use and the relationships between ecosystem services and ecological functions and properties of individual landscape components. On the basis of the methodology previously proposed by the authors, a wide range of ecosystem services of urban landscapes, mainly associated with soils and their ecological state, has been assessed. The cost of ecosystem services provided by the soil in urban landscapes is 20–30 times higher in comparison with that of green spaces, and some soil services can be considered invaluable because of the difficulty of renewing this natural resource. The cost of ecosystem services of undisturbed soils of park and recreational landscapes is 1.5–2 times higher than that of anthropogenically transformed soils of residential and residential-transport urban territories. The main contribution to the overall cost of ecosystem services of soils in urban landscapes is due to the following services: carbon sequestration, preservation of the genetic material of biota, and filtration and accumulation of chemical elements in the ecosystem. These services can be considered as promising in the monetization of ecosystem services in urban landscapes. The decline in the cost of ecosystem services from park and recreational landscapes to residential and residential-transport landscapes is largely determined by the deterioration of the ecological state of soils. The benefits provided by the natural block of landscapes are comparable to or greater than those of the cultural (human-created) block. In relation to the all-Russia assessment of ecosystem services, a specific feature of urban areas is a significant share (on average, 25%) of the cultural block in the total cost of ecosystem services and a decrease in the cost of regulatory services by about 30%. The results of the economic assessment of ecosystem services of urban landscapes indicate an underestimation of the value of natural components, a significant contribution of soil to the natural block, the need to search for simplified integral indicators of its state, and the presence of cost calculation problems. The methodological approaches and provisional results of this study can be used in urban planning with the aim to preserve the soil cover of urban landscapes and optimize their functioning.
