Soil occupation efficiency and landscape conservation in four Mediterranean urban regions

This study investigates the relationship between soil sealing and landscape conservation in four Mediterranean regions (Athens, Barcelona, Lisbon, Rome) characterized by different patterns of urban expansion. Per-capita sealed land, a landscape conservation index and selected territorial variables were considered into a multivariate exploratory framework aimed at assessing the correlation between land-use efficiency (based on the degree of soil sealing per-capita) and the quality of suburban landscape. A population density gradient with intensity of sealed land decreasing with the distance from the central city was observed in compact urban regions such as Athens and Barcelona. A mixed urban gradient was observed in Rome and Lisbon. In all the considered cities the spatial distribution of per-capita sealed land was not correlated with the urban gradient indicating that land consumption follows place-specific patterns irrespective of landscape quality. These findings suggest that urban containment and landscape conservation are policy targets requiring environmental measures irrespective of the prevailing morphology of the urban region (compact vs dispersed). In this context, green infrastructure planning is a promising tool for landscape conservation and the containment of soil sealing within fragile and dynamic contexts such as the wildland-urban interface.     

Urban greenspace delivery in Hong Kong: Spatial-institutional limitations and solutions

Hong Kong has developed an ultra-dense urban form dominated by buildings and roads with inadequate urban greenspace (UGS). Analyzing the fundamental constraints to UGS provision offers hints for improvements which are relevant to other compact cities. Twenty-five current issues regarding institutional and spatial limitations were evaluated with reference to three themes: open-space planning standards, urban-design guidelines and urban-greening governance. They were studied by interpreting relevant parts of government documents spanning the 1980s to 2015, map analysis, and field assessments. UGS standards of selected cities, and extensive research findings and practices reported in the literature specific to the respective constraints, have been enlisted for comparison and as the basis for formulating recommendations to improve delivery quantity and quality. The low local supply at merely 2.84 m²/person is tied down by outdated planning standards and policies which have remained unchanged for eight decades. UGS planning, design and management could be enhanced based on urban ecology and landscape ecology principles and best international practices, with suitable adjustments catering to local circumstances and the inordinately tight urban fabric. The package of suggested solutions in relation to the 25 institutional and spatial constraints could be considered for applications in other cities with compact precincts or undergoing densification to forestall problems and resolve difficulties.

Humanization of nature: Testing the influences of urban park characteristics and psychological factors on collegers’ perceived restoration

Previous studies have mainly focused on the independent role of landscape characteristics or preference on psychological restoration respectively. However, few studies have explored the complex relationships between restorative effects, landscape characteristics, preference and place bonding factors, particularly in urban parks. The development of new data environment and technique methods enables such a synthesis of innovative approach to reveal the influences of urban park characteristics and various psychological factors on collegers’ perceived restoration. A typical urban park in Wuhan, China, was selected for pilot study, in which 1560 crowdsourced images were collected using the Public Participation Geographic Information System (PPGIS) tool. With the help of Deep Learning techniques, landscape characteristics were combined with perceptual factors for the Partial Least Squares (PLS) based statistical analysis. It was found that some landscape properties, such as vegetation and water, presented indirect impacts in activating restoration via psychological mediators. The mediating effect of sense of place and the moderating effects of landscape characteristics on the preference-restoration nexus were revealed. These findings shed new light on the complex process in environmental restoration in which psychological and physical factors are intertwined. At the end, theoretical and managerial implications were proposed for the improvement of landscape planning in restoration studies.     

Perceptions of parks and urban derelict land by landscape planners and residents

As urban green spaces are important for residential satisfaction, human preferences are a key criterion in their design. However, preferences may vary between landscape planners and residents, which may result in differences between residents’ demands and the actual design. With urban derelict land becoming an important part of the urban green infrastructure, information about the perception and acceptance by residents compared to formal urban parks is important for their planning and design. It was thus examined how different types of urban green spaces are perceived by landscape planners and residents. Criteria for the classification of green spaces used by both participant groups were compared, as were the criteria that influenced preference.Participants sorted and rated photographs of parks and urban derelict land in two different tasks. Hierarchical cluster analyses and multidimensional scaling analyses were used to characterize the participants’ perceptual space. By conducting multiple regression analyses the resulting perceptual dimensions were related to preference.The identified perceptual criteria used to distinguish green spaces were degree of canopy closure, artificiality vs. naturalness, prospect, physical accessibility, and beauty. For residents, the degree of canopy closure was the most important criterion for classification; for landscape planners, it was artificiality. Preferences varied between groups: whereas landscape planners preferred rather natural areas with low accessibility and high species richness, the residents showed a greater preference for formal parks.As a practical implication, the study suggests that residents generally accept urban derelict land as recreational areas if a minimum of maintenance and accessibility is provided. When designing green spaces, landscape planners may consider these differences in their preferences compared to residents.

Mapping vegetation functional types in urban areas with WorldView-2 imagery: Integrating object-based classification with phenology

Mapping urban vegetation is a prerequisite to accurately understanding landscape patterns and ecological services provided by urban vegetation. However, the uncertainties in fine-scale vegetation biodiversity mapping still exist in capturing vegetation functional types efficiently at fine scale. To facilitate the application of fine-scale vegetation spatial configuration used for urban landscape planning and ecosystem service valuation, we present an approach integrating object-based classification with vegetation phenology for fine-scale vegetation functional type mapping in compact city of Beijing, China. The phenological information derived from two WorldView-2 imagery scenes, acquired on 14 September 2012 and 26 November 2012, was used to aid in the classification of tree functional types and grass. Then we further compared the approach to that of using only one WorldView imagery. We found WorldView-2 imagery can be successfully applied to map functional types of urban vegetation with its high spatial resolution and relatively high spectral resolution. The application of the vegetation phenology into classification greatly improved the overall accuracy of classification from 82.3% to 91.1%. In particular, the accuracies of vegetation types was improved by from 10% to 13.26%. The approach integrating vegetation phenology with high-resolution remote sensed images provides an efficient tool to incorporate multi-temporal data into fine-scale urban classification.     

Landscape changes and ecological studies in agricultural regions,Québec,Canada

Most landscape definitions in the western world are based on soil, climatic, or physiographic features and do not integrate humans as an integral part of the landscape. We present an approach where landscape types have been delineated in southern Québec, Canada based on current land use where anthropogenic and agricultural activities are concentrated as a practical application of the holistic approach in landscape definition. Landsat-TM satellite images were classified and the 27 habitat classes were regrouped into 5 general land cover classes (cash crop, dairy farming, forest, anthropogenic, wetlands) and overlaid onto soil landscape polygons to characterize natural boundary units. Cluster analyses were used to aggregate these polygons into seven agricultural types of land scape forming a gradient from urban and high-intensity cash crop farming activities to landscapes dominated by a mosaic of agriculture and forested areas. Multivariate analyses of raw data and of socio-economic and farming practices variables were used to describe the defined types of landscape and these were projected over three established land classification systems of southern Québec (Canadian ecoregions, North American Bird Conservation Initiative regions and Corn Heat Unit regions) to compare their similarity in terms of land cover and for planning of future ecological studies. Because agricultural landscapes are highly dynamic, they are bound to undergo changes in the near future. Our landscape delineation may serve as an experimental setup where land scape dynamics and wildlife populations and community structures could be monitored. Because the information we used to delineate and characterize agricultural landscape types is readily available in other countries, our approach could easily be adapted to similar data sources under and a wide variety of landscape types.
