Der Beitrag befasst sich mit der Analyse der zeitbezogenen Veränderung der Landschaft in der Nationalparkregion Sächsische Schweiz, d. h. der Änderung der Flächennutzung und ihrer Struktur über einen Zeitraum von etwa 200 Jahren hinweg. Dabei geht es primär um die Erfassung, Darstellung und Bewertung des Landschaftswandels durch Flächennutzungsänderungen und ihrer Auswirkungen auf die Umwelt. Durch die sehr enge methodische Verzahnung zwischen Fernerkundung, Geoinformatik-, landscape metrics- und umweltwissenschaftlichen Bewertungsansätzen gelingt es, Bewertungen der zeitbezogenen Strukturveränderungen in einem Landschaftsraum vorzunehmen und diese Veränderungen den verschiedenen, kumulativ zusammenwirkenden Verursachern zuzuordnen.

This thesis examines landscape change from 1889 to the present within the foothills-parkland ecoregion of Waterton Lakes National Park (WLNP) in southwestern Alberta, Canada. Land cover dynamics are explored qualitatively and quantitatively using Geographical Information Systems and a combination of historical and contemporary data sources including: (1) Dominion Land Survey (DLS) transect records (1889), (2) repeat oblique photographs (1914 and 2004) and repeat aerial photography (1939 and 1999). Results indicate a consistent increase in woody vegetation cover, particularly aspen forest cover, within the foothills-parkland since 1889, largely at the expense of native grasslands. The primary drivers of these changes likely include: climatic influences, changes to the historical grazing regime, the suppression of natural fire cycles and the cessation of First Nations’ land management practices. This research illustrates the value of integrating multiple historical data sources for studying landscape change in the Canadian Rockies, and explores the implications of this change for ecological restoration in the foothills-parkland of WLNP.

Esta pesquisa analisa a mudança da disponibilidade de bens e serviços ecossistêmicos em função do uso e ocupação da terra, no período de 1989, 2007 e 2014; e a valoração social de benefícios prestados por uma microbacia hidrográfica predominantemente urbanizada, inserida no ecótono Agreste (área de transição entre os biomas Mata Atlântica e Caatinga), no Nordeste do Brasil. Técnicas de sensoriamento remoto e sistema de informação geográfica foram utilizadas para quantificar as mudanças no uso e ocupação da terra na Microbacia Hidrográfica Riacho das Piabas, Paraíba. Método de transferência de benefícios foi aplicado para quantificar as mudanças na oferta de bens e serviços ecossistêmicos, entre os anos analisados. A percepção das partes interessadas (comunidade, técnico e especialista) acerca dos ambientes que ofertam bens e serviços ecossistêmicos na área de estudo e seus respectivos níveis de importância foram obtidos por meio de mapeamento participativo. A substituição de área de vegetação arbórea (46% da área de estudo em 1989 e 5% em 2014) por ambiente construído foi o fator-chave que impulsionou o declínio de 73% da disponibilidade de bens e serviços ecossistêmicos entre os anos de 1989 e 2014. A expansão urbana promoveu a perda de 89% da oferta de oito serviços ecossistêmicos, incluindo regulação do clima, regulação do fluxo de água, moderação de perturbações, ciclagem de nutrientes e controle biológico, que quando se considera a tendência regional de aridificação e as pressões existentes sobre os recursos hídricos, são relevantes localmente. Houve diferença significativa entre a percepção das partes interessadas quanto ao número de áreas mapeadas por seção de bens e serviços ecossistêmicos disponibilizados pela área de estudo para a população (Anova fatorial, F= 21,62; p< 0,001). A visão da comunidade sobre os benefícios oferecidos pela microbacia hidrográfica estudada distinguiu de técnicos e de especialistas. Os ambientes que mais ofertaram bens e serviços ecossistêmicos foram as áreas de transição entre ambiente dulcícola e terrestre; e espaços verdes. O serviço de manutenção do ciclo hidrológico e fluxos de águas apresentou média de nível de importância social muito alto. A gestão que deseja reduzir os impactos do processo de urbanização na provisão de bens e serviços ecossistêmicos deve considerar implementação do planejamento espacial baseado em ecossistemas, com foco na infraestrutura urbana verde e na restauração de habitats naturais e sua conectividade. Ademais, é fundamental abordar a percepção de partes interessadas no processo de planejamento e tomada de decisão para minimizar e gerenciar potenciais conflitos sociais. / Urbanisation has been a main cause of land use land cover (LULC) change worldwide, often with irreparable consequences to the provision of goods and ecosystem services that are fundamental to human physical, mental and spiritual well-being, as well as to the maintenance of life on the planet. This research analyzes the goods and ecosystem services availability change as a function of LULC, in the period of 1989, 2007 and 2014; and the social valuation of ecosystem benefits provided by a predominantly urbanised microwatershed, located in the Agreste ecotone (transition area between Atlantic Forest and Caatinga biomes), in Northeast Brazil. Remote sensing techniques and geographic information system were used to quantify LULC changes in Riacho das Piabas microwatershed, Paraíba. The benefit transfer method was applied to quantify changes in the ecosystem goods and services supply between the years analyzed. The stakeholders perception (community, technical and expert) about the environments that offer ecosystem goods and services in the study area and their respective importance levels were obtained through participatory mapping. Replacement of tree vegetation area (46% of the study area in 1989 and 5% in 2014) by the built environment was the key factor driving the 73% decline in the ecosystem goods and services availability between 1989 and 2014. Urban sprawl resulted losses of 89% in the eight ecosystem services supply, including climate regulation, water flow regulation, moderation of disturbance, nutrient cycling and biological control, which are critical locally when considering the regional trend towards aridification and the existing pressures on water resources. There was a significant difference between the stakeholders perception about the mapped areas number per ecosystem goods and services section available by the study area to the population (Factorial Anova, F = 21.62, p <0.001). The community perception about the benefits offered by the studied microwatershed distinguished from technicians and experts. The environments that most offered ecosystem goods and services were transitional areas between the between freshwater and terrestrial environments; and green spaces. The service maintenance of hydrological cycle and water flux presented very high average importance level. Management that wishes to reduce the urbanisation impacts on the provision of ecosystem goods and services should consider implementation of ecosystem-based spatial planning, focusing on urban green infrastructure and natural habitats restoration and their connectivity. In addition, it is fundamental to approach the stakeholders perception in the planning process and decision making to minimize and manage potential social conflicts.

Depuis l’avènement de l’agriculture productiviste, les paysages des zones d’intensification agricole des pays industrialisés ont été marqués par la perte sévère de leur diversité et la dégradation de leurs fonctions environnementales, récréatives, esthétiques et sociales. Au moment où la qualité des paysages constitue un facteur clé du dynamisme des collectivités rurales, il devient urgent de développer des stratégies d’aménagement aptes à réintroduire le caractère multifonctionnel de ces paysages. Dans ce contexte, cette thèse propose un éclairage sur les enjeux d’aménagement de ces paysages sous l’angle des approches dialectiques en paysage issues de la Holistic Landscape Ecology. En développant un modèle conceptuel des trajectoires des paysages s’inscrivant dans les approches intégrées en paysage, elle établit une double lecture des dynamiques physico-spatiale et socioculturelle des paysages des zones d’intensification agricole afin d’en arriver à qualifier les écarts entre celles-ci. Pour y parvenir, elle prend appui sur une étude de cas d’un bassin versant agricole du sud du Québec. En puisant tantôt dans l’écologie du paysage, tantôt dans la sociologie du paysage, les résultats de cette thèse soulignent d’une part le poids des forces politiques et économiques dans le façonnement de ces paysages. Mais ils révèlent également le rôle des valorisations paysagères des agriculteurs dans la modulation de ces forces. Plus encore, l’étude des dynamiques socioculturelles révèle une diversité au sein des populations locales au plan des valorisations de ces paysages et des pratiques qui les façonnent qui vient renouveler l’image d’uniformité de ces territoires. Le maintien et l’accentuation de cette diversité apparaissent susceptibles de contribuer significativement à la réintroduction du caractère multifonctionnel des paysages au sein des zones d’intensification agricole. Des pistes concrètes pour l’aménagement concluent cette thèse. / Since the advent of productivist agriculture, the landscapes in areas of intensive agriculture of industrialized countries have been affected by a drastic reduction in their diversity and the degradation of their environmental, recreational and aesthetic functions. At a time when the quality of landscapes is a key factor in the vitality of rural communities, it is becoming urgent to develop management strategies designed to reintroduce the multifunctional nature of these landscapes. Within this context, this thesis proposes to address the landscape management issues of areas of intensive agriculture under the perspective of dialectic approaches in landscape studies originating from Holistic Landscape Ecology. By developing a conceptual model of landscape trajectories, based on integrated landscape methods, it establishes a double interpretation of the physical-spatial and the social-cultural dynamics of the landscapes in areas of intensive agriculture in order to assess the degree of divergence between the two. To achieve this, an agricultural watershed of southern Québec was used as a case study. Sometimes using landscape ecology, sometimes using landscape sociology, the results of this thesis underline the strong influence of political forces in the shaping of these landscapes. However, they also reveal the important role of the landscape values of farmers in altering these forces. Moreover, the study of the social-cultural dynamics reveals that a diversity of landscape valuations, and of practices affecting landscapes, coexist within local populations, thus shedding new light on the usual image of uniformity of these landscapes. The maintenance and increase of this diversity appears likely to contribute significantly to the reintroduction of the multifunctional character of landscapes within areas of intensive agriculture. Concrete management recommendations conclude this thesis.
