Making land-use fit to planning goals. Weaknesses and opportunities within the Swiss land management regime

In Switzerland, the issue of land consumption has made it to the front of the political agenda in recent years. Studies conducted on a national level have concluded that there is an excess of land zoned for construction (ARE, 2008), which is seen as contributing to urban sprawl. This situation is looked upon as a failure of the Federal Law on Spatial Planning (LAT, 1979) and there is a political push to change it in order to reinforce zoning regulations. In this article, we look on the issue from a different angle. While there may be large quantities of land zoned for construction, in many urban areas land actually available for development is scarce. Building on the idea that planning's efficiency is linked to its capacity of influencing actual land-use, we focus on how this situation can be dealt with within the current Swiss institutional context.

Management and prognosis of status epilepticus according to hospital setting: a prospective study.

BACKGROUND: The treatment of status epilepticus (SE) is based on relatively little evidence although several guidelines have been published. A recent study reported a worse SE prognosis in a large urban setting as compared to a peripheral hospital, postulating better management in the latter. The aim of this study was to analyse SE episodes occurring in different settings and address possible explanatory variables regarding outcome, including treatment quality. METHODS: Over six months we prospectively recorded consecutive adults with SE (fit lasting five or more minutes) at the Centre Hospitalier Universitaire Vaudois (CHUV) and in six peripheral hospitals (PH) in the same region. Demographical, historical and clinical variables were collected, including SE severity estimation (STESS score) and adherence to Swiss SE treatment guidelines. Outcome at discharge was categorised as "good" (return to baseline), or "poor" (persistent neurological sequelae or death). RESULTS: Of 54 patients (CHUV: 36; PH 18), 33% had a poor outcome. Whilst age, SE severity, percentage of SE episodes lasting less than 30 minutes and total SE duration were similar, fewer patients had a good outcome at the CHUV (61% vs 83%; OR 3.57; 95% CI 0.8-22.1). Mortality was 14% at the CHUV and 5% at the PH. Most treatments were in agreement with national guidelines, although less often in PH (78% vs 97%, P = 0.04). CONCLUSION: Although not statistically significant, we observed a slightly worse SE prognosis in a large academic centre as compared to smaller hospitals. Since SE severity was similar in the two settings but adherence to national treatment guidelines was higher in the academic centre, further investigation on the prognostic role of SE treatment and outcome determinants is required.

Spatial planning to the test of property rights in Switzerland : an innovative land management approach to coordinate spatial planning goals with property rights interests

In Switzerland, the land management regime is characterized by a liberal attitude towards the institution of property rights, which is guaranteed by the Constitution. Under the present Swiss constitutional arrangement, authorities (municipalities) are required to take into account landowners' interests when implementing their spatial planning policy. In other words, the institution of property rights cannot be restricted easily in order to implement zoning plans and planning projects. This situation causes many problems. One of them is the gap between the way land is really used by the landowners and the way land should be used based on zoning plans. In fact, zoning plans only describe how landowners should use their property. There is no sufficient provision for handling cases where the use is not in accordance with zoning plans. In particular, landowners may not be expropriated for a non-conforming use of the land. This situation often leads to the opening of new building areas in greenfields and urban sprawl, which is in contradiction with the goals set into the Federal Law on Spatial Planning. In order to identify legal strategies of intervention to solve the problem, our paper is structured into three main parts. Firstly, we make a short description of the Swiss land management regime. Then, we focus on an innovative land management approach designed to implement zoning plans in accordance with property rights. Finally, we present a case study that shows the usefulness of the presented land management approach in practice. We develop three main results. Firstly, the land management approach brings a mechanism to involve landowners in planning projects. Coordination principle between spatial planning goals and landowners' interests is the cornerstone of all the process. Secondly, the land use is improved both in terms of space and time. Finally, the institution of property rights is not challenged, since there is no expropriation and the market stays free.

Urban Governance und nachhaltige Quartiere: Ein Beitrag zur Förderung einer dauerhaft nachhaltigen Stadtentwicklung

Seit den 1990er Jahren werden zunehmend nachhaltige Quartiere realisiert. Dabei besteht häufig eine beachtliche Diskrepanz zwischen den Zielen, die von den beteiligten Akteuren angestrebt werden, deren Umsetzung (Realisierungsphase) und deren Erhalt auf Dauer (Nutzungsphase). Es stellt sich folglich die Frage, auf welche Weise die Projektqualität im Sinne einer nachhaltigen Quartiersentwicklung verbessert werden kann. Diese Projekte sind jedoch enorm komplex aufgrund der großen Interdisziplinarität und Interdependenz ihrer Ziele sowie der vielschichtigen Akteursstrukturen. Sie stellen daher be-sonders hohe Anforderungen an die Projektsteuerung. Das konkrete Ziel dieser Arbeit besteht darin, die Bedeutung einer Prozesssteuerung im Sinne von Urban Governance zur Realisierung und zum Erhalt nachhaltiger Quartiere zu untersuchen. Damit soll einen Beitrag zur Förderung einer nachhalti-gen Stadtentwicklung geleistet werden. Die Arbeit stützt sich auf ein umfassendes theoretisches Fundament zum Thema Governance, wobei die relevanten Elemente für den Kontext nachhaltiger Quartiere herausgearbeitet werden. Die Hypothesen prüfen die Bedeutung der Schlüsselcharakteristika von Urban Governance (Kooperation, Partizipation, Verhandlungen) für die Projektqualität während der Realisierungs- und Nutzungsphase. Eine erste empirische Untersuchung wurde an zwanzig europäischen nachhaltigen Modellquartieren vorgenommen. Stärken und Schwächen aus der Perspektive der Nachhaltigkeit werden analysiert, deren Ursachen identifiziert und Handlungsoptio-nen aufgezeigt. Die Erkenntnisse zeigen die Notwendigkeit einer Verbesserung der Projektsteuerung während der Realisierungs- und der Nutzungsphase. Auf der Grundlage dieser Erkenntnisse wird ein umfassender Ansatz zur empirischen Untersuchung von Urban Governance im Kontext nachhaltiger Quartiere entwickelt. Dieser beruht auf dem akteurzentrierten Institutionalismus und den Merkmalen der Urban Governance. Anhand dieses Ansatzes wird mithilfe von Experteninterviews der Realisierungsprozess des nach-haltigen Quartiers Kronsberg (Hannover) analysiert. Betrachtet werden dabei die beteiligten Akteure und ihre Handlungso-rientierungen, die verwendeten Schlüsselinstrumente sowie aufgetretene Divergenzen zwischen Akteuren und deren Auswirkungen auf die Projekt- und Prozessqualität. Eine Vertiefung relevanter Themenfelder wird anhand der Fallstudie Neu-Oerlikon (Zürich) vorgenommen. Diese empirische Arbeit zeigt, dass eine Prozesssteuerung im Sinne von Urban Governance im Vergleich zu einer klassis-chen hierarchischen Steuerung eine notwendige aber nicht hinreichende Bedingung zur Verbesserung der Projektqualität nachhaltiger Quartiere darstellt. An konkreten Beispielen wird herausgearbeitet, dass der Mehrwert einer solchen Steuerung nur unter bestimmten Voraussetzungen erzielt werden kann: In manchen Situationen ist die Steuerungsform Kooperation und die Interaktionsform Verhandlung in ihrer Wirksamkeit zur Sicherung der Projektqualität begrenzt und hierarchische Interventionen sind notwendig. Nicht ein bestimmtes Steuerungsmodell per se ist geeignet, sondern es kommt auf den Ein-zelfall an: auf die Akteursstruktur, die individuellen und institutionellen Handlungsorientierungen der Akteure und deren Ver-haltensweisen, die Rahmenbedingungen und die Ausgestaltung des Urban Governance-Prozesses. Wenn die Spielregeln dieses Prozesses von den Akteuren nicht wirklich angenommen und gelebt werden, dominieren individuelle und institutio-nelle Akteursinteressen zu Lasten der Projektqualität. Ferner zeigen die Untersuchungen, dass die Partizipation der zukünftigen Quartiersnutzer in der Praxis häufig unzureichend ist. Dies führt zu Einbußen in der Projektqualität. Entscheidend ist auf jeden Fall, dass mindestens ein Akteur, in der Regel die öffentliche Hand, präsent ist, der die Definition anspruchsvoller Nachhaltigkeitsstandards, deren Umsetzung und deren Erhalt sichert sowie die notwendigen Rahmenbedingungen dafür schafft. Diese Arbeit belegt darüber hinaus, dass der Erhalt der Projektqualität während der Nutzungsphase (Faktor Zeit) bisher un-zureichend beachtet und in die Projektplanung einbezogen wird. Gerade dieser Aspekt bestimmt aber, ob das Quartier auch auf Dauer dem Nachhaltigkeitsanspruch gerecht werden kann! Tatsächlich handelt es sich um einen fortlaufenden Prozess, der nicht mit der Einweihung des Quartiers abgeschlossen ist. Vor diesem Hintergrund werden relevante Handlungsfelder beschrieben und die Notwendigkeit der langfristigen Fortsetzung einer Steuerung im Sinne von Urban Governance bzw. der Herausbildung einer Urban Governance-Kultur aufgezeigt. Aus den empirischen Erhebungen werden Erfolgs- und Risikofaktoren für Urban Governance-Prozesse während der Realisierungs- und der Nutzungsphase abgeleitet. Ferner werden bisher vernachlässigte Handlungsfelder (langfristiges Umwelt-management, ökologische Finanzierungsformen, urbane Landwirtschaft, Umweltkommunikation, etc.) eruiert. Die Berücksichtigung dieser Erkenntnisse ist unerlässlich für eine Verbesserung der Projektqualität nachhaltiger Quartiere. ---------------------------------------------- Gouvernance urbaine et quartiers durables: Entre intensions et mise en oeuvre --- Résumé --- Depuis les années 90, la thématique des quartiers durables a gagné en importance, même si leur développement s'est avéré difficile. Le décalage entre les objectifs, leur mise en oeuvre et le projet tel qu'il est vécu par ses habitants est souvent important et nécessite d'être réduit. Un quartier durable est par nature un projet complexe, aux objectifs ambitieux situé à la croisée de multiples champs disciplinaires, mobilisant de nombreux acteurs aux intérêts divergents. De plus, chaque projet, du fait des ses spécificités, requiert un pilotage adapté. L'objectif principal de la recherche vise à analyser la nature du pilotage du processus de conception, de réalisation et d'exploitation des quartiers durables. Ses résultats ont pour ambition de contribuer à optimiser et promouvoir le développement urbain durable. Le fondement théorique de la recherche se base sur le concept de gouvernance urbaine, adapté au contexte particulier de la gouvernance des quartiers durables. La gouvernance urbaine, au sens où nous l'entendons, est un mode de pilotage basé sur la coopération entre les acteurs publics et privés. Les hypothèses centrales du travail testent la portée et les limites des caractéristiques-clefs de la gouvernance urbaine (coopération, participation, négociation), ainsi que l'importance de la notion de pérennité pour la qualité du projet. Dans un premier temps, nous avons analysé vingt quartiers durables modèles européens et identifié leurs atouts et leurs faiblesses en termes de durabilité, ainsi que leurs divers modes de pilotage. Les enseignements tirés de ces exemples révèlent la nécessité d'améliorer le pilotage des projets. Dans un deuxième temps, nous avons élaboré une grille d'analyse fine fondée sur l'approche institutionnelle des acteurs et les caractéristiques-clefs de la gouvernance urbaine. En nous appuyant sur cette grille, nous avons analysé le processus de conception et de réalisation du quartier durable de « Kronsberg » (Hanovre) à l'aide des éléments suivants : les acteurs (avec leurs intérêts et objectifs propres), les instruments d'aménagement du territoire, les modes de pilotage, les zones de divergence et de convergence entre les acteurs, ainsi que leurs impacts sur le processus et le projet. Dans un troisième temps, les hypothèses centrales ont été testées sur le quartier de « Neu-Oerlikon » (Zurich) afin d'approfondir et d'élargir les enseignements tirés de celui de « Kronsberg ». Les résultats des analyses mettent en évidence le fait qu'un pilotage de projet selon le modèle de la gouvernance urbaine est certes une condition nécessaire mais non suffisante pour améliorer la qualité du projet. De plus, la valeur ajoutée de la gouvernance urbaine n'est valable qu'à certaines conditions. En effet, la coopération et la négociation peuvent même, dans certaines situations, réduire la qualité du projet ! Le principal enseignement de la recherche révèle qu'il n'y a pas de mode de pilotage idéal, mais que la qualité d'un projet dépend d'une multitude de facteurs, tels que les constellations d'acteurs, leurs intérêts personnels et institutionnels, les conditions cadres et les « règles du jeu » de la gouvernance urbaine. Si les « règles du jeu » en particulier ne sont pas réellement appropriées par l'ensemble des acteurs, les intérêts et les comportements personnels ou institutionnels prédominent au détriment de la qualité du projet. De même, si la participation des futurs usagers à l'élaboration du projet de quartier durable n'est pas assurée, tant la qualité du projet que sa pérennité en pâtissent. Nous avons également constaté que la présence d'un acteur (en règle générale les autorités publiques) qui veille à la définition d'objectifs ambitieux en matière de développement durable et à leur application constitue un apport essentiel à la qualité du projet. En outre, la recherche met en évidence les carences dans le suivi et le maintien à long terme des qualités de durabilité de la phase d'exploitation des projets de quartiers durables analysés. Dans la phase d'exploitation, le degré de coopération diminue généralement et les modes de fonctionnement et de pilotage sectoriels se mettent en place au détriment de la qualité du projet. Cela confirme la nécessité de poursuivre le processus de pilotage selon le modèle de la gouvernance urbaine au-delà de la phase de réalisation des projets. La recherche précise les enjeux des champs d'action de la phase d'exploitation (domaine encore peu étudié) et démontre la pertinence du mode de pilotage préconisé. Enfin, les analyses permettent d'identifier des facteurs de réussite et de risque susceptibles d'influencer les systèmes de gouvernance urbaine, ainsi que les enjeux des domaines de la durabilité encore négligés (agriculture urbaine, gestion environnementale dans la durée, comportement des usagers, financement équitable, etc.). La prise en compte de ces enseignements est essentielle à l'amélioration de la gestion de futurs projets de quartiers durables. ---------------------------------------------- Urban Governance and Sustainable Neighbourhoods: A Contribution to a Lasting Sustainable Development --- Abstract --- Since the 1990s, sustainable neighbourhoods have become an increasingly important topic. However, their development has proven to be difficult. There is an often considerable gap, which must be reduced, between the initial goals, the way they are implemented and how the project is finally inhabited. A sustainable neighbourhood is inherently a complex project, with ambitious goals that lie at the intersection of multiple disciplines, involving numerous stakeholders with diverging interests. Moreover, each project, due to its specific characteristics, requires an adapted steering. The main goal of this research is to analyse the nature of the steering process during the planning, realisation and use of sustainable neighbourhoods. The results aim to contribute to the promotion of sustainable urban development. The theoretical foundation of this research is based on the concept of urban governance, adapted to the particular context of sustainable neighbourhoods. Urban governance is understood in this work, as a mode of project steering based on the cooperation between public and private stakeholders. The central hypotheses of this work test the importance and the limits of the key characteristics of urban governance (cooperation, participation, negotiation) as well as the importance of continuity for the project quality. To begin with, we surveyed and analysed twenty exemplary European sustainable neighbourhoods and identified their strengths and weaknesses in terms of sustainability, as well as their diverse steering modes. The lessons learned from these examples reveal the need to improve the projects' steering. Secondly we elaborated a detailed framework for analysis founded on stakeholder-centred institutionalism and the key characteristics of urban governance. By systematically applying this framework, we analysed the planning and implementation process of the sustainable neighbourhood "Kronsberg" (Hannover). Our focus was on the following dimensions: the stakeholders (with their particular interests and goals), the instruments of spatial planning, the steering modes, the points of divergence and convergence amongst the stakeholders, as well as their impacts on the process and on the project. The final step was to test the core hypotheses on the neighbourhood "Neu-Oerlikon" (Zürich) in order to broaden the lessons learned from "Kronsberg". The results of the analysis highlight the fact that an urban governance type project steering is certainly a necessary but insufficient condition to improve the project quality. Moreover, the added value of urban governance is only valid under certain conditions. In fact, cooperation and negotiation can even in certain situations reduce the project's quality! The main lesson of this research is that there is not an ideal steering mode, but rather that the quality of the project depends on numerous factors, such as the stakeholder constellation, their individual and institutional interests, the general conditions and the "rules of the game" of urban governance. If these "rules of the game" are not really appropriated by all stakeholders, individual and institutional interests and behaviours predominate at the expense of the project's quality. Likewise, if the future users' participation in the project development is insufficient, both the project's quality and its continuity suffer. We have also observed that the presence of a stakeholder (in general the public authorities) who ensures the definition of ambitious goals in terms of sustainable development and their implementation is crucial for the project's quality. Furthermore, this research highlights the deficiencies in the follow-up and long-term preservation of the sustainability qualities in the neighbourhood projects which we have analysed. In the use phase, the degree of cooperation generally diminishes. Attitudes and project management become more sectorial at the expense of the project's quality. This confirms the need to continue the steering process according to the principles of urban governance beyond the project's implementation phase. This research specifies the challenges that affect the use phase (a still neglected area) and shows the relevance of the recommended steering mode. Finally, the analyses also identify the success and risk factors that may influence urban-governance systems, as well as the challenges of still neglected fields of sustainability (urban agriculture, long-term environmental management, user behaviour, fair funding, etc.). Taking into account these outcomes is essential to improve the management of future sustainable-neighbourhood projects.

Safety of a new algorithm for the management of childhood illness (Almanach) to improve quality of care and rational use of drugs

Introduction New evidence from randomized controlled and etiology of fever studies, the availability of reliable RDT for malaria, and novel technologies call for revision of the IMCI strategy. We developed a new algorithm based on (i) a systematic review of published studies assessing the safety and appropriateness of RDT and antibiotic prescription, (ii) results from a clinical and microbiological investigation of febrile children aged <5 years, (iii) international expert IMCI opinions. The aim of this study was to assess the safety of the new algorithm among patients in urban and rural areas of Tanzania.Materials and Methods The design was a controlled noninferiority study. Enrolled children aged 2-59 months with any illness were managed either by a study clinician using the new Almanach algorithm (two intervention health facilities), or clinicians using standard practice, including RDT (two control HF). At day 7 and day 14, all patients were reassessed. Patients who were ill in between or not cured at day 14 were followed until recovery or death. Primary outcome was rate of complications, secondary outcome rate of antibiotic prescriptions.Results 1062 children were recruited. Main diagnoses were URTI 26%, pneumonia 19% and gastroenteritis (9.4%). 98% (531/541) were cured at D14 in the Almanach arm and 99.6% (519/521) in controls. Rate of secondary hospitalization was 0.2% in each. One death occurred in controls. None of the complications was due to withdrawal of antibiotics or antimalarials at day 0. Rate of antibiotic use was 19% in the Almanach arm and 84% in controls.Conclusion Evidence suggests that the new algorithm, primarily aimed at the rational use of drugs, is as safe as standard practice and leads to a drastic reduction of antibiotic use. The Almanach is currently being tested for clinician adherence to proposed procedures when used on paper or a mobile phone

Geospatial approach for defining the Wildland-Urban Interface in the Alpine environment

Problems related to fire hazard and fire management have become in recent decades one of the most relevant issues in the Wildland-Urban Interface (WUI), that is the area where human infrastructures meet or intermingle with natural vegetation. In this paper we develop a robust geospatial method for defining and mapping the WUI in the Alpine environment, where most interactions between infrastructures and wildland vegetation concern the fire ignition through human activities, whereas no significant threats exist for infrastructures due to contact with burning vegetation. We used the three Alpine Swiss cantons of Ticino, Valais and Grisons as the study area. The features representing anthropogenic infrastructures (urban or infrastructural components of the WUI) as well as forest cover related features (wildland component of the WUI) were selected from the Swiss Topographic Landscape Model (TLM3D). Georeferenced forest fire occurrences derived from the WSL Swissfire database were used to define suitable WUI interface distances. The Random Forest algorithm was applied to estimate the importance of predictor variables to fire ignition occurrence. This revealed that buildings and drivable roads are the most relevant anthropogenic components with respect to fire ignition. We consequently defined the combination of drivable roads and easily accessible (i.e. 100 m from the next drivable road) buildings as the WUI-relevant infrastructural component. For the definition of the interface (buffer) distance between WUI infrastructural and wildland components, we computed the empirical cumulative distribution functions (ECDF) of the percentage of ignition points (observed and simulated) arising at increasing distances from the selected infrastructures. The ECDF facilitates the calculation of both the distance at which a given percentage of ignition points occurred and, in turn, the amount of forest area covered at a given distance. Finally, we developed a GIS ModelBuilder routine to map the WUI for the selected buffer distance. The approach was found to be reproducible, robust (based on statistical analyses for evaluating parameters) and flexible (buffer distances depending on the targeted final area covered) so that fire managers may use it to detect WUI according to their specific priorities.

Urban environments and situated institutions : everyday governance in west Bengal

How do processes of power shape the urban environment in small Indian cities? On a day-to-day basis, who actually controls access to and the use of environmental resources? How is this done? Answering these questions contributes to our ability to develop a nuanced understanding the urban condition. In order to investigate these questions an actor-oriented approach is developed, drawing on the anthropological literatures on everyday governance and the everyday state. This conceptual framework informs an urban political ecology approach oriented towards everyday practices and the micro-politics of the (re)production of urban socio-natures. This thesis employs a mixed methods approach to qualitative research. Three cases are presented to explore: para (neighbourhood) clubs as governance actors, the governance of the urban pondscape, and the urban political ecology of solid waste management. These case studies serve to highlight how power shapes the (re)production of urban socio-natures through the everyday environmental governance practices of a complex network of governance actors. This work further demonstrates how multiple intersectionalities, including class, caste and access to political and social authority, shape these practices and their outcomes. Finally, the manner in which balances of power, place making and the formation of subject positions may both result from and shape everyday environmental governance practices and their outcomes is explored. This empirical investigation makes a number of contributions to the literature. It has explores the hereto-understudied topics of environmental governance in small cities in India, the urban political ecologies of non-piped water and of solid waste, and the role of clubs as governance actors. It further contributes to conversations within the literature on how to deepen and broaden Urban Political Ecology by engaging with everyday practices, and cases of ordinary, not-openly contested socio-natures. -- Comment les processus de pouvoir influencent-ils l'environnement urbain dans les petites villes indiennes ? Au quotidien, qui contrôle l'accès et l'utilisation des ressources environnementales ? Comment ce contrôle s'exerce-t-il ? Répondre à ces questions contribue au développement d'une compréhension nuancée de la condition urbaine. Afin d'explorer ces questions une approche actor-oriented de la gouvernance quotidienne est développée, faisant appel aux littératures anthropologiques de la gouvernance quotidienne et de l'everyday state. Ce cadre conceptuel établit ainsi une approche d'Urban Political Ecology orientée vers les pratiques quotidiennes et la micro- politique de la (re) production des socio-natures urbaines. Cette thèse emploie des méthodes qualitatives mixtes. Trois cas sont présentés afin d'étudier : les clubs para (quartier) comme acteurs de la gouvernance; la gouvernance de la pondscape urbaine; et l'urban political ecology de la gestion des déchets solides. Ces études de cas permettent de mettre en lumière la façon dont le pouvoir influence la (re)production des socio-natures urbaines par le biais des pratiques quotidiennes de gouvernance environnementale d'un réseau complexe d'acteurs. Ce travail démontre également comment plusieurs intersectionnalités, y compris la classe, la caste et l'accès au pouvoir politique et social, façonnent ces pratiques de gouvernance et leurs produits. Finalement, cette recherche explore la manière dont les équilibres de pouvoir, la fabrication de lieux et la formation de la position du sujet peuvent à la fois résulter de et contribuer à façonner les pratiques quotidiennes de gouvernance environnementale et leurs produits. Cette investigation empirique fait ainsi plusieurs contributions à la littérature. Elle explore les questions jusque-là sous-étudiées de la gouvernance environnementale dans les petites villes en Inde, de l'urban political ecology de l'eau non courante et des déchets solides, ainsi que du rôle des clubs comme acteurs de la gouvernance. Celle-ci contribue également à des débats sur la façon d'approfondir et d'élargir l'urban political ecology en travaillant sur les pratiques quotidiennes, et sur des cas de socio-natures ordinaires, pas ouvertement contestées.
