Conceptions of justice in the planning of the new urban landscape – Recent changes in the comprehensive planning discourse in Malmö, Sweden

The Swedish Planning and Building Act (PBL) from 1987, revised in 2011, stipulates that an important task of comprehensive planning is to secure both substantive and procedural justice. However, because of the municipal planning monopoly, the individual municipalities are free to decide how these goals can best be achieved. This article focuses on the ways interpretations of justice have changed over a 10-year period in one selected municipality, Malmö in southern Sweden. Analyses of the comprehensive planning discourse in this municipality reveal that when it comes to substantive justice, discussions of structural inequality and segregation have gradually been replaced by discussions of social cohesion, while at the same time discussions of procedural justice and the need to create public spheres in which underprivileged groups are allowed a voice, have been replaced by discussions of open public spaces, allowing different groups to see each other. Though the issue of social justice seems to be downplayed in the urban planning discourse for the time being, counterforces within city administration are questioning the prevailing line of development.     

The appropriation and transformation of the landscape: the urbanization process resulting from the cultivation of the erva mate in Paraná (Brazil)

This paper aims to describe the landscape patterns and the urbanization process which evolved due to the mate tea (Ilex paraguariensis St. Hill) cultivation in the Brazilian state of Paraná. Drinking mate tea is an ancient tradition of the Guarani Indians who settled the southeastern region of South America. The large-scale cultivation of mate in Paraná has been taking place for centuries, mainly in the region around the city of Irati. Mate cultivation induced the development of settlements and influenced their growth; it stamped the economic and social character of the region, and shaped a rich and characteristic landscape. As other cultural landscapes, the ‘mate landscape’ is undergoing changes, with agriculture and urbanization being the most important drivers. To sustain its values it is necessary to call for attention to its environmental, economic, social and cultural virtues. We discuss the ecological and aesthetic value of mate culture, and the social and environmental demands of its future. We also offer arguments and some ideas to create from the landscape a significant community added value, bearing in mind that landscape is a key element of the quality of life and an important asset for future generations.     

Valley landscape management: the context of a ‘river contract’ in the Semois valley,Belgium

A trans‐boundary and multi‐disciplinary approach to the river contract project for the Semois valley in Wallonia (Belgium) is described that provided the opportunity for a landscape‐scale focus during actions to restore the watercourses and the associated valley area. A trans‐boundary landscape survey was carried out under the context of the Interreg III European programme. This resulted in the rediscovery of lost views and viewpoints within the landscape and in the implementation of actions leading to the opening up of the valley, which provided opportunities to re‐establish lost landscape features, such as hay meadows. The gathering of many partners in the negotiation process of this project can be seen as an example of ‘landscape democratization’ or participative management of landscapes in a trans‐boundary and trans‐disciplinary context and as such this project is a concrete realization of the aims of the European Landscape Convention (ELC).     

From urban beautification to a holistic approach: the discourses of ‘landscape’ in the Arab Middle East

The English word and Western idea of landscape was introduced during the colonial restructuring of Arab cities in the early decades of the twentieth century. Thereafter, landscape came to be understood predominantly in the context of urban modernity, associated with the Western picturesque tradition adopted in landscaping municipal parks and public urban spaces. The formal conception that prevails today precludes a broader appreciation of landscape as a source of livelihood, the fabric of lived-in experiences and collective identities, just as it reduces the scope of landscape architecture, an emerging profession in the Arab Middle East, to urban beautification. Inspired by the integrative and community-centred conception advanced by the European Landscape Convention, this paper argues for a holistic landscape approach that contributes to development while responding to regional environmental and ecological constraints. The methodology of ecological landscape design is applied to secure a holistic reading of people and place and to engender integrative solutions that address socio-economic, environmental and heritage concerns. A selection of projects are cited to demonstrate the potential of a holistic approach in changing current limited perceptions of landscape and in expanding the discourse of landscape in the region beyond the current focus on appearance and beautification.     

Botanical relics of a lost landscape: herborising ‘upon the Cliffs about the Pharos’ in Genoa,March 1664

This paper uses approaches derived from historical ecology to show how knowledge can be gained about the historical and cultural value of neglected urban landscapes. We study the area around Genoa’s lighthouse and consider the long-term survival of individual plant species and some implications for landscape conservation. We examine topographical representations over the last 500 years to establish the landscape context of the lighthouse. We then analyse the records of plants collected by two English naturalists of the seventeenth century, John Ray and Francis Willughby, and demonstrate how the plants were identified and documented. We survey the current vegetation to establish whether any species identified in 1664 still grow at the site. This exploration of botanical ancestry at a local scale makes it possible to demonstrate cultural–historical values of the lighthouse rocks and their vegetation which should be considered as part of the cultural heritage of the city of Genoa.     

Toward a sustainable land management of vernacular landscape in the highlands of south‐western Saudi Arabia: indigenous and statutory experiences

The vernacular landscape of the highlands of south‐western Saudi Arabia comprises three distinct elements: natural, agricultural and built. The highlands are currently facing land use planning problems which result in deforestation, despite significant attempts at afforestation by several governmental agencies (especially the Ministry of Agriculture and Water) and by municipal governments in the area. Intentions towards more sustainable forms of land management now characterize official documents. With regard to landscape issues, this is marked by a discourse of sustainable land management and the sponsorship of initiatives addressing the relationship between land management and the environment. This paper demonstrates that the approach to sustainable land management is technical, rational and scientific. A more balanced approach would combine scientific knowledge and practice with traditional expertise.     

‘This is not the jungle,this is my barbecho’: semantics of ethnoecological landscape categories in the Bolivian Amazon

Through a case study with Spanish-speaking Takana indigenous people in the Bolivian Amazon, we explored ethnoecological landscape categories, including their ecological underpinnings, cultural significance and hierarchical organisation. Using field walks and interviews with consultants, we elicited 156 ethnoecological landscape categories, 60 of which related to vegetation types. However, sorting exercises with landscape photographs revealed that vegetation was not a guiding organisation principle. Takana consultants organised ethnoecological landscape categories into geographical regions that contained different landscape features, including vegetation units, topographical or hydrological features. Comparing the documented ethnoecological landscape categorisation with a published scientific botanical classification of vegetation units, we observed some important conceptual differences, which in turn have implications for the management of such landscapes.     

Assessing landscape preferences: a visual choice experiment in the agricultural region of Märkische Schweiz,Germany

Natural amenities and the aesthetic value of agricultural landscapes are important territorial assets for improving rural tourism and the quality of the living environment. To identify which characteristics shape the visual quality of a landscape, a stated-preference survey was conducted (N = 200) using photorealistic landscape visualisations of four different landscape attributes (point green elements, linear green elements, crop diversity and presence of livestock). We estimated respondents’ preferences for landscape attributes, examined the extent of agreement among respondents and identified socio-economic factors influencing their responses. Results revealed that point elements had the highest general preference. About 70% of respondents preferred diverse and highly structured landscapes, while about 30% of respondents had opposing preferences. Preferences were also found to be dependent on the individual’s sociocultural background, such as their level of education, gender or age. These results can help to improve the multi-objective targeting of policies by including an aesthetic value perspective.     

Energy landscape: Los Angeles Harbor and the establishment of oil-based capitalism in Southern California, 1871–1930

In the first three decades of the twentieth century, the Los Angeles metropolitan area emerged as the fastest growing urban–industrial economy on the Pacific Coast. This was a significant achievement for a city without a natural harbour. Despite formidable barriers presented by physical geography, the gradual development of a deep-water harbour in Los Angeles was fundamental to the emergence of oil-based capitalism in Southern California. In the first three decades of the twentieth century, under the municipal governance of a Board of Harbor Commissioners, private oil companies developed Los Angeles Harbor into a modern transhipment facility comprising infrastructures and technologies dedicated to the efficient transportation, storage, and refining of petroleum and petroleum-based products. From this perspective, Los Angeles Harbor needs to be understood as a long-term, fixed-capital investment into oil-based energy as fuel for industry and transportation. As a transhipment facility, Los Angeles Harbor also functioned as a critical outlet for surplus energy after the discovery of several large fields in the Los Angeles Basin in the early 1920s. By focusing on a particular built landscape, this paper aims to contribute insight into how geographies of fixed-capital investment play a role in the regional dynamics of energy transition and establishment.     

Detecting people’s and landscape’s identity in a changing mountain landscape. An example from the northern Apennines

Mountain areas in the northern Apennines (Italy) were historically characterised by rural landscapes. Since the 1950s, rapid and widespread land abandonment caused large transformations in the landscape that resulted in a landscape identity crisis. Currently, many people continue to identify and associate themselves with a landscape that no longer exists, whilst others identify themselves with a future landscape that as yet does not exist. This paper explores the concept of landscape identity through empirical research based on a series of in-depth interviews, examination of the contextualised conspicuous spatial and temporal changes and consideration of individual and collective identities. Therefore, firstly, factors influencing the changes in landscape identity through time are identified and, secondly, so-called ‘tipping points’ and their consequential impacts on landscape identity loss or change are detected. Finally, it is the intention of this article to explore and discover the ways in which the concept of landscape identity can be approached and employed in a continuously changing environment.     

Introduction to a special issue: the future of landscape characterisation,and the future character of landscape – between space,time, history,place and nature

Abstract

In any discussion of landscape characterisation the elephant in the room is the question of just what is landscape? Another way of putting this question is to simply ask: ‘How would you characterise landscape?’ What this implies is that there is a certain circularity in landscape characterisation because, through the very act of characterising landscape, one is also defining what one means by landscape. The European Landscape Convention’s definition of landscape as ‘an area, as perceived by people, whose character is the result of the action and interaction of natural and/or human factors’ suggests a similar circularity because the character of an area, as it results from the action of natural and/or human factors, is dependent upon human perception, which is presumably also, in addition, one of the human factors acting upon the landscape. This circularity, or ‘circulating reference’, to use Bruno Latour’s term, is fundamental to Denis Cosgrove’s analysis of the origin of the modern concept of landscape as scenic space, and his analysis, we would suggest, helps explain some of the questions raised in this special issue concerning landscape characterisation and the future character of landscape .     

The impact of abandoned/disused marble quarries on avifauna in the anticline of Estremoz,Portugal: does quarrying add to landscape biodiversity?

Although the extractive operations of quarrying are often considered environmental threats, there is some evidence that abandoned quarries may have a significant positive impact on biodiversity by enhancing habitat quality for several species. In Estremoz Anticlinal, SE Portugal, many of the existing marble quarries have been inactive for decades and were abandoned without any restoration project in progress. The impact of quarry abandonment on avifauna diversity was assessed relative to reference conditions using adjacent rural fields as control areas. No significant differences were found in within-community diversity (alpha diversity) between abandoned quarries and reference sites. However, several dissimilarity indices showed a clear divergence in species composition between abandoned quarries and reference sites. Furthermore, statistically significant differences in species compositions were found between quarries abandoned for different periods. Over time, species composition becomes more similar to that observed in reference sites, reflecting ecological succession and landscape resilience to quarrying. Nevertheless, the studied quarrying landscape exhibited higher gamma and beta diversity than the former traditional landscape; thus, our results suggest that abandoned quarries, rather than damaging and destroying niches, can promote new ecological niches and significantly diversify rural landscapes.     

Changes in the distribution patterns of trace metals in sediments of the mersey estuary in the last decade (1974–1983)

A survey of the trace metal distribution in the sediments of Liverpool Bay, and the Dee and Mersey estuaries in 1972–1974 has been followed by a series of regular monitoring surveys in the Mersey estuary during the last 10 years. Over 15 000 individual observations have been recorded, including measurements of the trace metal content (cadmium, chromium, cobalt, copper, lead, manganese, mercury, nickel and zinc), organic carbon content and particle size distribution. In parallel with the physical and chemical measurements, a limited biological sampling programme has also been carried out.These results are discussed in relation to the spatial and temporal variability detected, and in relation to the potential biological effect of the sedimentary trace metals.     

Use of Geophysical Techniques for the Localization of the Restricting Zones of Permeability in the Bottom of Basin： Forecasting the Zones of Clogging

Measurements of dielectric parameters followed by permeability tests are performed on soil samples of infiltration basin. The dielectric parameters are obtained by TDR （time domain reflectrometry） measurements from which it is found that the measurement of the permittivity, the electrical conductivity and the relaxation time of compacted soil allows the mapping of the values of the coefficient of permeability at the surface of an infiltration basin. With the distribution of the coefficient of permeability, the areas of water stagnation can be detected before the basin filling. The study proves that the TDR measurements for the detection of these zones can be used for the management of infiltration basins for sustainable working and their remediation can be undertaken before the rainy seasons.     

Analysis of the causality links between the growth of the construction industry and the growth of the macro‐economy in Ghana

A vibrant construction industry in a developing country, that mobilizes human and local material resources in the development and maintenance of buildings, housing and physical infrastructure, is an important means to promote increased local employment and accelerate economic growth. Ghana, a country of about 22 million people, currently has one of the fastest growing economies in West Africa. The Government of Ghana (GOG) has recently set a target of annual economic growth rate of 8% and above, up from annual growth rates of 5–6% in the past five years (2001–05). It intends to use the agricultural sector as the major vehicle for achieving such high growth rates in order for the country to reach the status of a middle income country by 2015. Surprisingly, the construction industry was left out from the list of major growth drivers of the economy. We contend that with the construction industry currently making up the third largest sector of the economy, special attention should be given to this industry as one of the main drivers of economic growth in Ghana. Therefore we conducted a study to analyse the causality links between the growth in the construction industry and the growth in the macro‐economy of Ghana, measured by the gross domestic product (GDP), to ascertain whether the construction industry can be used to lead the entire economy on a growth path. The analysis was based on a simple Granger causality test using time series data from 1968 to 2004. We showed that growth in the construction industry Granger‐caused growth in GDP, with a three‐year lag. The construction industry needs to be considered as one of the major drivers of economic growth in Ghana.
