La « crise environnementale » médiatisée sous la forme d'une série de dommages et de menaces qui pèsent sur la survie de notre espèce (Larrère, 1997) oblige nos sociétés à prendre en compte des êtres et des phénomènes qui ne sont pas humains et que nous avions exclus de notre sphère morale. Plus largement, ces enjeux questionnent la façon dont nous nous organisons pour agir dans les espaces que nous partageons de facto avec une pluralité d'entités. Cette recherche doctorale s'intéresse plus particulièrement aux pratiques de gestion des « espaces de nature ». Les gestionnaires de ces espaces sont amenés à répondre à une multiplicité de demandes et d'injonctions, autrement dit à « écologiser » leurs façons de faire. Mais bien traiter la « nature » ou l'environnement ne peut se faire au détriment d'un bon accueil des publics. Nous observons et décrivons la mise en place de quatre initiatives se disant « éthiques » ou « responsables » sur des terrains variés, du plus urbain (espaces verts de Grenoble) au plus « sauvage » (Mt Jefferson Wilderness, en Oregon). Il apparaît que la responsabilité du devenir de ces espaces n'est pas uniquement celle des gestionnaires : elle est distribuée le long d'une chaîne d'humains et de non-humains. Les acteurs comptent sur une pluralité de personnes, d'êtres et de choses pour maintenir ces espaces. Leurs pratiques relèvent d'expérimentations tout à la fois scientifiques, politiques et morales (Latour, 1995 ; Hache, 2011). Ils construisent des compromis situés et précaires, selon une éthique du faire-avec. Dans ce mouvement, les parcs et jardins – comme figures de la séparation et de la domestication – cessent d'être la seule échelle pertinente de réflexion et d'action : d'autres formes socio-spatiales émergent. Une géographie des associations hétérogènes (Murdoch, 1997) nous apparaît alors féconde pour rendre compte des liens, des emboîtements d'échelles et des évènements éthiques fragmentaires qui se jouent dans le travail continu de ces collectifs qui œuvrent à construire un monde commun constamment renégocié. / The “environmental crisis”, made public through various damages and threats that challenge the survival of our species (Larrère, 1997), urges our societies to include beings and phenomena that are not solely human into our moral sphere. Also, it requires to re-think the way we plan our activities in spaces than we share de facto with a large number of entities. This doctoral research focuses on “natural areas” management policies. Park and wilderness managers have to comply with an increasing diversity of norms and rules, they have to “ecologize” the way they do things. But caring for “nature” or the environment can hardly exclude the well-being of humans. We analyse four management projects labelled as “ethical” or “responsible” on different terrains, from Grenoble city parks (France) to Mt Jefferson Wilderness (Oregon). The responsibility concerning the future of these “natural areas” appears to no longer be only that of the managers: it is distributed along a chain of humans and non humans. People in charge of these areas count on many individuals and things. Their actions can be considered as experiments that are altogether scientific, politic and moral (Latour, 1995; Hache, 2011). They build site-specific precarious compromises following an ethics of coping. In this context, parks and wildernesses cease to be relevant scales of action and other socio-spatial forms emerge. A geography of heterogeneous associations (Murdoch, 1997) seems to offer one interesting means of following the links operating in these attempts to build a common world.

Estas instalações podem agrupar diversas tecnologias em um único sistema, cujo funcionamento leva à economia de energia e redução de gastos com transporte, o que pode redundar em um balanço energético positivo. Todavia, se mal planejada, a implantação e funcionamento das CTRSs podem causar impactos ambientais negativos aos recursos hídricos, ar atmosférico e à saúde dos seres vivos, em particular da população humana. Por isso, as fases de planejamento e implantação devem estar em consonância com o processo de Avaliação de Impacto Ambiental, sendo indispensável a realização de estudos para a seleção de áreas ambientalmente compatíveis com o seu funcionamento. Este trabalho tem como objetivo apresentar e discutir o desenvolvimento de um mapeamento geoambiental voltado à seleção adequada de áreas para a implantação de CTRSs, tendo como foco de aplicação o pequeno município paulista de Santa Cruz da Conceição, que apresenta expressiva inconformidade ambiental em relação à gestão dos resíduos sólidos e destinação final dos rejeitos; em torno dele, num raio de 100 km, vive uma população de cerca de 7,4 milhões de pessoas. A integração de informações obtidas com o levantamento bibliográfico efetuado, a geração de banco de dados (incluindo fatores físicos, biológicos e sócio-econômicos) e a análise multicriterial em ambiente SIG conduziram à elaboração do referido mapeamento. Este teve como base fundamental estudo prévio de compartimentação fisiográfica da região do município, levando-se em conta principalmente os aspectos de permeabilidade, resistência a erosão e estabilidade a movimentos gravitacionais, que foram integrados com dados de fragmentos de vegetação, declividade, áreas de gerenciamento de risco aviário de aeródromos regionais, informações do plano diretor municipal e normas técnicas e legais. Entre os resultados obtidos com o trabalho, destaca-se, centralmente, a definição de áreas propícias à implantação de CTRSs, incluindo incineradores, e de aterros sanitários em valas e em camadas. Áreas incompatíveis para estas ações também foram reconhecidas. Este estudo oferece elementos para discussões e tomadas de decisão ligadas ao processo de implantação de Centrais de Tratamento de Resíduos e empreendimentos a elas associados, sendo aplicável a outros municípios brasileiros. É, portanto, contribuição para a estruturação de um ordenamento territorial sustentável. / Technological development and Solid Waste Treatment Plants (SWTPs), including landfills, may lead to good solutions to the process of treatment and recovery of urban solid waste. These facilities can group various technologies into a single system, whose operation leads to energy savings and reduction of transportation costs, which may result in a positive energy balance. However, if not properly planned, the setting up and operation of SWTPs can cause negative environmental impacts to water resources, atmospheric air and the health of living beings, in particular the human population. Therefore, the phases of planning and setting up of a SWTP should be in line with the process of Environmental Impact Assessment, and it is essential to carry out studies for the selection of environmentally compatible areas of functioning. This study presents and discusses the development of a geo-environmental mapping focused on the proper selection of areas for the implementation of SWTPs, with the application focus on the municipality of Santa Cruz da Conceição, a small town in the state of São Paulo, which presents significant environmental nonconformity in relation to management solid waste and disposal of waste; around it, within a radius of 100 km, lives a population of about 7.4 million people. The integration of information obtained from the literature performed, the generation of database (including physical, biological and socio-economic elements) and multi-criteria analysis in GIS environment led to the preparation of this mapping. This work had as fundamental element a previously established physiographic subdivision of the area, and took into account mainly the aspects of permeability, erosion resistance and stability to gravitational movements; these parameters have been integrated with information on fragments of vegetation, declivity, poultry risk management areas in regional aerodromes, information on director municipal plan, and legal and technical standards. Among the results obtained from this work, there is, centrally, the definition of areas for setting up a SWTP, including incinerators and landfills (in ditches and in layers). Incompatible areas for these actions were also recognized. This study provides elements for discussion and decision-making related to the implementation process of waste treatment plants and projects associated with them, being applicable to other municipalities. It is therefore contributing to the structuring of a sustainable land use.

The thesis is devoted to the evaluation of land consolidation procedure in selected countries compared to the one in the Czech republic. Evaluated were countries where there is the possibility of comparison of historical connections, economic development, ecological consciousness and legislative maturity and flexibility. A contrast between Germany and Ukraine illustrates the determination of the Czech republic. There were the Czech republic, Ukraine, France and Germany analyzed. The thesis is divided into four basic parts, each of them focused to one of the previously mentioned states.

The control and eradication of the invasive biennial herb garlic mustard (Alliaria petiolata) and the restoration of invaded forest habitats present important linked challenges to land managers in North America. Removing garlic mustard by hand and by glyphosate herbicide application have both been used as eradication strategies with mixed results. Each method has advantages and disadvantages, but they are rarely compared for effectiveness and community impact across multiple years of management. Some previous studies have shown improvements in species diversity and plant community composition following management, while others have found no differences. To better understand both garlic mustard population and native plant community responses to these two methods across a broad geographic range, we tested these two management methods for four years in seven northern hardwood forests in Massachusetts and New York State. We found that pulling juvenile and adult garlic mustard plants for four years significantly reduced adult abundance, while spraying had no effect compared to invaded control plots. In the plant community, we found no negative impacts of garlic mustard on species diversity nor increased diversity in managed plots following three consecutive years of management. Our results suggest that increased diversity should not be the primary goal of garlic mustard management at these sites and plant community monitoring at the site-specific scale should be explored. This study highlights how complicated decisions can be for managers when deciding which invasions to prioritize and how to measure plant community recovery.

abstract: For more than 100 years, the Unite States National Park Service (NPS) has been guided by a mandate to preserve parks and their resources for the enjoyment of present and future generations. But all parks are subject to conditions that may frustrate preservation efforts. Climate change is melting the glaciers. Rising seas are sweeping away protected shorelines. Development projects, accompanied by air, water, light, and noise pollution, edge closer to parks and fragment habitats. The number of visitors and vested interests are swelling and diversifying. Resources for preservation, such as funds and staff, seem to be continuously shrinking, at least relative to demand. Still, the NPS remains committed to the preservation of our natural and cultural heritage. Yet the practice of that promise is evolving, slowly and iteratively, but detectably. Through explorations of legal and scholarly literature, as well as interviews across the government, non-profit, and academic sectors, I’ve tracked the evolution of preservation in parks. How is preservation shifting to address socio-ecological change? How has preservation evolved before? How should the NPS preserve parks moving forward? The practice of preservation has come to rely on science, including partnerships with academic researchers, as well as inventory and monitoring programs. That shift has in part been guided by goals that have also become more informed by science, like ecological integrity. While some interviewees see science as a solution to the NPS’s challenges, others wonder how applying science can get “gnarly,” due to uncertainty, lack of clear policies, and the diversity of parks and resources. “Gnarly” questions stem in part from the complexity of the NPS as a socio-ecological system, as well as from disputed, normative concepts that underpin the broader philosophy of preservation, including naturalness. What’s natural in the context of pervasive anthropogenic change? Further, I describe how parks hold deep, sometimes conflicting, cultural and symbolic significance for their local and historical communities and for our nation. Understanding and considering those values is part of the gnarly task park managers face in their mission to preserve parks. I explain why this type of conceptual and values-based uncertainty cannot be reduced through science. / Dissertation/Thesis / Doctoral Dissertation Biology 2019

In der Region Leipzig hat sich das Projekt StadtLandNavi zum Ziel gesetzt, die Entwicklung der Kulturlandschaft und der Bedarfe an Wohnbauflächen besser planen und einschätzen zu können. Dies geschieht vor dem Hintergrund einer Region, welche zeitlich und räumlich nah beieinander liegenden Wachstums- und Schrumpfungsprozessen unterliegt. Um eine bessere und dynamischere Informationsversorgung zu gewährleisten, soll unter anderem ein Stadt-Land-Management-Werkzeug entwickelt werden, welches den Akteuren in der Region aktuelle und auf die Fragestellung angepasste Informationen liefert. Schwerpunkt ist weiterhin die bedarfsorientierte Analyse der Inhaltstiefe und räumliche Betrachtungsebene. Für die Bereitstellung der dazu notwendigen Daten, Informationen und Visualisierungen in einem interkommunalen Geoportal nach der Projektlaufzeit wurden mögliche technische Umsetzungswege analysiert und mit den Bedarfen abgeglichen. Diese dienen als Abstimmungs-Basis für eine zukünftige Verankerung bei einem oder mehreren Akteuren in der Region.

Since the signing of their Final Agreement and Self-Government Agreement in 2003, Kluane Fist Nation (KFN), located primarily in the southwestern Yukon, has been navigating their post-settlement realities as an autonomous self-governing First Nation. According to the Canadian state, these Agreements intended to achieve certainty for all Parties, including certainty over jurisdiction, and KFN's ability to govern their own land and peoples. Two decades into the implementation of their Agreements, I ask, what has been achieved in actuality? In partnership with Kluane First Nation, this research sought to produce results KFN desired and found valuable. As such, it explores KFN's chosen topic of Traditional Leases, alongside essential entwined elements such as KFN's enactment of value, their navigation of uncertain and precarious land claim legislation as techniques of jurisdiction and territoriality, and taking control of research within their Traditional Territory. This exploration stems from our research partnership, my ethical commitments to KFN, and research's methods and methodologies. I argue that in their work with researchers, and their policies and practices on the land, KFN is enacting their vision for a meaningful and good life, within ongoing settler-colonial attempts to maintain control. KFN is engaging in and enacting what they find valuable in their use of their land despite ever-increasing obstacles, and often in ways which remain invisible to the settler-state.

<p dir="ltr">The expected rapid development of renewable energy in the United States has raised concerns about its effects on farmland prices, yet there is little empirical evidence on the impact of solar energy development on farmland prices. This study aims to examine the heterogenous impact of commercial and utility-scale solar energy on farmland prices in Indi- ana. Drawing on farmland transactions from 2015 to 2020, we employ quantile and expectile hedonic price regressions to estimate the heterogeneous impact of proximity to solar energy facilities across the conditional price distribution. This study finds an inverse, non-linear relation between the proximity to solar energy and per acre land prices. We find that solar farms provide a premium to neighboring farmland parcels. However, this premium is heterogenous, with higher premiums on parcels with higher conditional prices. As we move across the higher conditional expectiles, we observe a price drop ranging from 0.8% (0.1 expectile) to 1.8% (0.9 expectile) for an additional mile increase from neighboring solar farms. Similarly, price premium for a proximity to solar energy is as high as 2.1% for 99th expectile farmland price. Thus, policymakers should consider the effect of solar energy to avoid potential damage on agricultural production and land price movements.</p>
