Economic and demographic decline are significant factors in the generation of brownfield land. Small brownfield sites can create negative images of neighbourhoods, attracting anti-social behaviour and having detrimental effects on communities. This deters investment, creating a downward spiral of neglect and market failure. Despite the policy emphasis placed on reuse and removing the blight associated with brownfield sites, there is a paucity of studies relating to the issue of, a) small sites and b) specifically derelict sites. This leads to a lack of reliable data and problems for the evidence base which informs the development of policy. This study explores the effects of unenumerated small scale land dereliction on cities and communities in social and economic terms. The study takes a mixed methods approach including a three-tier case study focusing on the development of the derelict land issue in Liverpool. Liverpool is considered to be the most deprived local authority in England and has experienced long term demographic decline and depression and as such has a high proportion of derelict and vacant land. Despite being the focus of a plethora of regeneration initiatives, Liverpool still has a large number of derelict sites, the majority of which are smaller than 0.25 hectares.

The practice of restoring and reinhabiting derelict rural houses is a growing, but relatively unexplored, phenomenon in contemporary Sweden. Frequently highlighted as a movement in public media, the practice is framed as the expression of more sustainable, heritage-sensitive and societally beneficial lifestyles, and has spurred interest from several municipalities. The views held by restorers and enthusiasts, and the extent to which these correspond with the perspectives highlighted in media, have however been largely unknown. The present thesis makes use of the phenomenon’s strong social media presence to bridge this knowledge gap, and examines discursive approaches to derelict house restoration, heritage and sustainable resource consumption brought forward in the Facebook group ”I rescued a derelict house!”. 30 posts and 475 comments from the group have been manually scraped and analysed based on the methodology of Foucauldian Discourse Analysis. The results suggest that approaches among restorers and enthusiasts are multifaceted and internally contested, with dichotomous notions of past versus present, and common versus private, complicating approaches to heritage and marginalising sustainable resource use. While several perspectives were brought forward, the contestation between them seemingly hinders both collective mobilisation, and discursive renegotiation. This calls the narrative curated by media into question, and points to the frictions ensuing when spaces in the borderland between decay and domestication are discussed on the Internet. It is proposed that future municipal, and academic, efforts may benefit from taking these frictions into account.

This project explores a reinterpretation process of a deindustrial site through landscape architecture. By using the industrial process to guide the formation of the landscape, spaces, and experiences, a semi-abandoned industrial site is transformed into a cultural park. The purpose of the project is to articulate the intriguing qualities of a deindustrial site and respond to them through a design process that is sensitive to the history and character of the site, while allowing contemporary uses and experiences to evolve. / February 2008

The decision-making model was developed that allows solving multi-attribute problems of derelict buildings management from the perspective of sustainable development and under uncertainty. The model deals with the problem of developing the derelict buildings’ redevelopment variants and choosing the most rational one. Planning and technical components of an effective model in conformity with the main principles of sustainable development were proposed. The model of the sustainability indicator system for management of derelict buildings was designed. The developed system was applied to multi-attribute decision-making. A comparative analysis of the results was developed. The model was adjusted for modelling and evaluating the rational management of derelict rural buildings in Lithuania. The facilities of GIS for a spatial decision-making were adjusted to the analyzed problem of sustainable revitalization of derelict buildings.

La restauration des fonctions des sols est une étape clé de la requalification des sites dégradés par les activités humaines. Ces opérations nécessitent de disposer de procédés de remise en état du couvert pédologique favorisant la résilience écologique. Ils génèrent de nouveaux sols dont il faut prévoir l’évolution. Notre objectif est de caractériser le fonctionnement et la pédogenèse de sols construits à l’aide d’un nouveau procédé fondé sur la formulation de déchets et sous-produits (terre industrielle traitée, sous-produit papetier, compost). Dans ce but, des colonnes en laboratoire ainsi que des parcelles lysimétriques in situ ont été mises en place. Des paramètres descriptifs des fonctionnalités et de la pédogenèse des sols construits ont été mesurés. Les résultats ont montré que les matériaux parents présentent des propriétés aptes à remplir des fonctions comme la fourniture d’éléments ou la rétention en eau. Les sols construits remplissent les rôles de support de végétation, d’échange/filtre et de support de la biodiversité comme des sols naturels. Les premiers stades de leur évolution pédogénétique se caractérisent par leur intensité, leur rapidité et leur caractère non habituel (e.g. dissolution conjointe de gypse et de calcite). La prospective sur l’évolution des sols construits démontre que, de Technosols, ils évoluent vers des types de sols analogues aux sols naturels. Ce cheminement nous conduit à proposer une évolution de la classification des sols très anthropisés sur des critères génétiques. Enfin, les bases de la modélisation de la pédogenèse des sols très anthropisés sont posées ainsi que celles d’un outil d’aide à la décision pour le génie pédologique / Human activities induce growing impacts on soils. This has produced derelict lands that need thorough reclamation to minimize their negative effect on the environment. A better knowledge and control of the evolution of highly anthropized soils is needed in order to achieve a sustainable management of these sites. This work emphasizes on both the development of a process of soil construction with wastes and by-products (paper sludge, treated industrial soil, compost) and the study of the functioning and pedogenic evolution of the constructed soils. The project relies on both in situ pilot scale application and lab-scale experiments. The characterization of the parent materials and their compounding highlighted their properties and their originalities compared to geological or pedological materials. The study of the functioning of constructed soils demonstrated that they could fulfil the soil basic functions. In this way, the process has been able to achieve the reclamation of the pedological cover and initiate the ecological resilience. The nature, the intensity and the kinetics of the pedogenic processes have been identified. It appeared that the reactions were very fast and that they sometimes strongly differ from the natural local pedo-climate (e.g. dissolution of gypsum, amorphous silica). We suggest that they will spontanuously evolve to analogous natural form of soils. Our results are confronted with the present classification of the Technosols and some propositions are made in favour of a more genetic-oriented way. Some thoughts about the modelling of the pedogenesis of very anthropized soils are proposed. At last, this work evocates the basis for the development of a decision tool for the pedo-engineering approach.
