Mitigating high air temperatures and heat waves is vital for decreasing air pollution and protecting public health. To improve understanding of microscale urban air temperature variation, this paper performed measurements of air temperature and relative humidity in a field of Wuhan City in the afternoon of hot summer days, and used path analysis and genetic support vector regression (SVR) to quantify the independent influences of land cover and humidity on air temperature variation. The path analysis shows that most effect of the land cover is mediated through relative humidity difference, more than four times as much as the direct effect, and that the direct effect of relative humidity difference is nearly six times that of land cover, even larger than the total effect of the land cover. The SVR simulation illustrates that land cover and relative humidity independently contribute 16.3% and 83.7%, on average, to the rise of the air temperature over the land without vegetation in the study site. An alternative strategy of increasing the humidity artificially is proposed to reduce high air temperatures in urban areas. The study would provide scientific support for the regulation of the microclimate and the mitigation of the high air temperature in urban areas.

Rapid Pace

With the rapid pace of urbanization, land-use change is essential for economic and social progress; however, it does not come without costs. With such rapid urbanization, there comes pressure on the land and its resources, like that of food and timber production with a significant impact on the livelihood of millions of people. With the loss of agricultural land due to developmental activities, future agriculture would be very intensive. Therefore, it is likely with the existing pattern of allocating land uses for future development that we may lose the ecosystem services and highly productive agricultural lands. The value of these ecosystem services to agriculture is enormous and often underappreciated. The study focuses on identifying underlying causes of the land-use change, ecosystem services affected due to land-use change in peri-urban areas of Chandigarh using spatial mapping of affected ecosystem services and suggesting proposals for promoting agricultural ecosystem values using economically-informed policy instruments.

. Population growth, economic development and rural-urban migration have caused rapid expansion of urban areas and metropolitan regions in Turkey. The structure of urban administration and planning has faced different socio-economic and political challenges, which have hindered the structured and planned development of cities and regions, resulting in an irregular and uneven development of these regions. We conducted detailed comparative analysis on spatio-temporal changes of the identified seven land-use/cover classes across different regions in Turkey with the use of Corine Land Cover (CLC) data of circa 1990, 2000, 2006 and 2012, integrated with Geographic Information System (GIS) techniques. Here we compared spatio-temporal changes of urban and non-urban land uses, which differ across regions and across different hierarchical levels of urban areas. Our findings have shown that peri-urban areas are growing more than rural areas, and even growing more than urban areas in some regions. A deeper look at regions located in different geographical zones pointed to substantial development disparities across western and eastern regions of Turkey. We also employed multiple regression models to explain any possible drivers of land-use change, regarding both urban and non-urban land uses. The results reveal that the three influencing factors-socio-economic characteristics, regional characteristics and location, and development constraints, facilitate land-use change. However, their impacts differ in different geographical locations, as well as with different hierarchical levels.

The Impact

The densification of urban areas has raised concerns over increased pluvial flooding. Flood risk in urban areas might increase under the impact of land use changes. Urbanisation involves the conversion of natural areas to impermeable areas, causing lower infiltration rates and increased runoff. When high-intensity rainfall exceeds the capacity of an urban drainage system, the runoff causes pluvial flooding in low-laying areas. In the present study, a long time series (i.e., 20 years) of geo-referenced flood claims from property owners has been collected and analysed in detail to assess flood risk as it relates to land use changes in urban areas. The flood claim data come from property owners with flood insurance that covers property loss from overland flooding, groundwater intrusion through basement walls, as well as flooding from drainage systems; these data serve as a proxy of flood severity. The spatial relationships between land use change and flood occurrences in different urban areas were analysed. Special emphasis was placed on examining how nature-based solutions and blue-green infrastructure relate to flood risk. The relationships are defined by a statistical method explaining the tendencies whereby land use change affects flood risk.

Globally, urbanization is increasing at an unprecedented rate at the cost of agricultural and forested lands in peri-urban areas fringing larger cities. Such land-cover change generally entails negative implications for societal and environmental sustainability, particularly in South Asia, where high demographic growth and poor land-use planning combine. Analyzing historical land-use change and predicting the future trends concerning urban expansion may support more effective land-use planning and sustainable outcomes. For Nepal’s Tarai region—a populous area experiencing land-use change due to urbanization and other factors—we draw on Landsat satellite imagery to analyze historical land-use change focusing on urban expansion during 1989–2016 and predict urban expansion by 2026 and 2036 using artificial neural network (ANN) and Markov chain (MC) spatial models based on historical trends. Urban cover quadrupled since 1989, expanding by 256 km2 (460%), largely as small scattered settlements. This expansion was almost entirely at the expense of agricultural conversion (249 km2). After 2016, urban expansion is predicted to increase linearly by a further 199 km2 by 2026 and by another 165 km2 by 2036, almost all at the expense of agricultural cover. Such unplanned loss of prime agricultural lands in Nepal’s fertile Tarai region is of serious concern for food-insecure countries like Nepal.

Animal-mediated pollination is required for the reproduction of the majority of angiosperms, and pollinators are therefore essential for ecosystem functioning and the economy. Two major threats to insect pollinators are anthropogenic land-use change and the spread of pathogens, whose effects may interact to impact pollination. Here, we investigated the relative effects on the ecosystem service of pollination of (i) land-use change brought on by agriculture and urbanization as well as (ii) the prevalence of pollinator parasites, using experimental insect pollinator-dependent plant species in natural pollinator communities. We found that pollinator habitat (i.e. availability of nesting resources for ground-nesting bees and local flower richness) was strongly related to flower visitation rates at the local scale and indirectly influenced plant pollination success. At the landscape scale, pollination was positively related to urbanization, both directly and indirectly via elevated visitation rates. Bumblebees were the most abundant pollinator group visiting experimental flowers. Prevalence of trypanosomatids, such as the common bumblebee parasite Crithidia bombi, was higher in urban compared with agricultural areas, a relationship which was mediated through higher Bombus abundance. Yet, we did not find any top-down, negative effects of bumblebee parasitism on pollination. We conclude that urban areas can be places of high transmission of both pollen and pathogens.

Abstract Land-use planning generally aims to manage the development of urban areas to address the needs of the communities. In this regard, the multiple and often competing environmental, economic and social conflicts complicate the process of land-use planning. Commercial development in residential neighbourhoods is a common type of land-use conflict that can dramatically exacerbate these potential conflicts. Over the recent decades, many affluent neighbourhoods of Tehran Metropolis (the capital of Iran) have been confronted with an unbridled development of commercial activities within the residential areas. This paper seeks to understand the process of land-use change and its impacts on the residents’ quality of life in an affluent neighbourhood of Tehran Metropolis (Gisha Neighbourhood) by adopting a combination of quantitative and qualitative methods of impact assessment including semi-structured interview, purposeful field survey, and traffic survey. The results yield that incompatible land-use policies of the Tehran Comprehensive Plan and structural defects in the land-use change regulations led to an unbridled process of commercialisation which intensified non-local activities with city/regional service coverage along the main streets of Gisha Neighbourhood. The analysis demonstrates that despite improving the accessibility of residents to urban facilities and reducing their travel time/cost, the process of land-use changes in Gisha Neighbourhood declined the residents’ quality of life by its considerable negative effects on socio-cultural structures, landuse patterns, traffic flow, and human health in the residential areas of the neighbourhood.

The spatial transformation of new urban areas into industrial urban areas impacts spatial structure, spatial patterns, and environmental degradation. This study aims to analyze the spatial transformation work as a determinant of the development of the new urban area of Metro Tanjung Bunga Makassar and analyze the relationship of spatial expansion, land use change and population increase for the growth of new city areas and the sustainable development of the Metro Tanjung Bunga area, Makassar city. The data for this study has been obtained through observation, surveys and documentation. The research approach used is a sequential explanation. According to the results, that excessive urbanization and maximum compaction led to spatial expansion towards the development of the new urban area of Metro Tanjung Bunga. Moreover, the increase in number has a dominant influence with a value of 32.3% on the growth of the new city area of Metro Tanjung Bunga, Makassar City. Spatial expansion, land use change, and population increase were determinants of growth factors in the new urban areas and they also had a significant impact on environmental quality degradation. This study recommends the importance of considering the impact of new urban spatial areas for the formulation of strategic policies on sustainable development as an effort to meet national development targets for the case of Metropolitan Cities in Indonesia.

The urban heat island phenomenon occurs in urban areas. It is characterized by increased temperature of both the air and ground surface, compared to the surrounding rural landscape, and is a typical feature of the urban climate. As this phenomenon may affect quality of life in the cities, a variety of scientific studies have been carried out. The article provides a review and evaluation of selected published studies devoted to the issue of the urban heat island, from the point of view of the application of land cover and land use data in the 3-dimensional microscale urban model. Part of the review brings into focus the MUKLIMO model, which computes the atmospheric conditions in urban landscapes and predicts thermal and other climatic characteristics. Evaluated studies confirmed the correlation between the land cover/land use classes and occurrence of the urban heat islands, i.e. a higher percentage of impermeable surfaces within the urban heat island causes more intensive thermal manifestation. The urban heat island effect diminishes when there are less impermeable surfaces and a greater representation of urban greenery in land cover/land use classes.
