Identificação e valoração sociocultural dos serviços ecossistêmicos - o caso da comunidade de Marujá, Ilha do Cardoso - SP, Brasil / Socio-cultural identification and valuation of ecosystem services the case of Marujá community, Cardoso Island SP, BrazilCamila Jericó Daminello 05 December 2014 (has links)
A intensa relação entre sistema econômico e ambiental é tema de discussões e análises de diversas áreas de estudo, mas foi com o surgimento da Economia Ambiental e, posteriormente, da Economia Ecológica que este tópico teve o seu destaque. Mesmo com diferenças substanciais ambas as áreas têm como um dos seus objetivos a identificação e quantificação dos recursos e processos naturais que apresentam utilidade humana, chamados atualmente de serviços ecossistêmicos, através da técnica de valoração ambiental. Dependendo de seu enfoque, a valoração ambiental pode apresentar cálculos e concepções diferentes. Basicamente, existem três esferas de valor dos serviços ecossistêmicos: a econômica, a ecológica e a sociocultural. Por questões metodológicas, de definição e, principalmente, de relutância em discutir questões socioculturais, a última esfera se apresenta pouco desenvolvida e aplicada. A motivação de modificar este quadro se encontra na busca de um melhor entendimento dos diferentes usos dos serviços ecossistêmicos, com destaque para os chamados serviços ecossistêmicos culturais, a fim de uma tomada de decisão que se baseie nas três esferas de valor. Assim, com o objetivo de contribuir para o desenvolvimento da faceta sociocultural da valoração dos serviços ecossistêmicos, o presente estudo foi construído. Para isso, foi proposta e testada uma nova metodologia que permite a identificação (Free listing) e valoração sociocultural (Índice de Saliência de Smith) dos serviços ecossistêmicos através das respostas de comunitários quando submetidos a um questionário semi-estruturado específico. O estudo foi conduzido na Comunidade do Marujá, situada na Ilha do Cardoso, litoral sul do Estado de São Paulo. No total, 53 moradores tradicionais (representando 88% das famílias) foram questionados sobre suas relações, utilitárias, pessoais e comunitárias, com o ecossistema de praia que ladeia a comunidade. Ao todo, 18 serviços ecossistêmicos foram identificados, alguns descritos pela primeira vez, e classificados em três categorias, uma delas também criada neste estudo. Numa análise geral, Alimento, Trabalho e serviços ecossistêmicos culturais, como Identidade de Lugar apresentam os valores mais altos. A utilização de Free listing em conjunto com o Índice de Saliência de Smith se mostrou uma metodologia interessante para a identificação e valoração dos serviços ecossistêmicos a partir do envolvimento de uma população local. Seus resultados são consistentes e permitem a comparação com outros estudos, além de poderem ser utilizados, juntamente com valores de outras esferas, para a composição de um quadro mais completo de tomada de decisão. / The intense relationship between economic and environmental systems has been discussed and analyzed in several areas of study, but it was with the advent of Environmental Economics and, subsequently, the Ecological Economics that this topic had its prominence. Even with substantial differences, both areas have as common objective, the identification and quantification of natural resources and processes that have human utility, also known as ecosystem services. This can be done by environmental valuation techniques. Depending on its approach, environmental valuation has different outcomes, methods and concepts. In general, there are three spheres of ecosystem services values: the economic, the ecological and the socio-cultural one. Because of methodological limitations, definition problems and, mainly, the reluctance in discussing cultural issues, the last sphere is poorly developed and applied. The motivation for modifying this situation is the search for a better understanding of ecosystem services\' different uses, with emphasis on the so-called cultural ecosystem services in order to take decisions that are based on the three spheres of value. Thus, with the objective of contributing to the development of the cultural sphere of ecosystem services valuation, the present study was constructed. A new methodology was therefore proposed and tested: this methodology allows the identification (Free-listing) and sociocultural valuation (Smiths Salience Index) of ecosystem services through the response of a community when submitted to a semi-structured questionnaire. The study was conducted in Marujá community, situated on the Cardoso Island, south coast of Sao Paulo State. In total, 53 traditional residents (representing 88% of households) were asked about their relationship, utilitarian, personal and community, with the community beach ecosystem. In all, 18 ecosystem services were identified. Some were described for the first time, and classified into three categories, one of which was also first assessed in this study. In a general analysis, \"Food\", \"Job\" and cultural ecosystem services, such as \"Sense of place\" have the highest values. The use of Free-listing in conjunction with the Smiths Salience Index appeared to be an interesting methodology for the purpose of identification and valuation of ecosystem services through local population. The results are consistent and allow comparison with other studies. In addition, it can be used together with other sphere values in order to compose a more complete framework for decision-making purpose.

[en] ANALYSIS AND SPATIAL DISTRIBUTION OF ECOSYSTEM SERVICES IN THE CITY OF RIO DE JANEIRO / [pt] ANÁLISE E DISTRIBUIÇÃO ESPACIAL DOS SERVIÇOS ECOSSISTÊMICOS DA CIDADE DO RIO DE JANEIROCARINE SZNECZUK DE LACERDA 14 March 2022 (has links)
[pt] Os serviços ecossistêmicos (SE) são os benefícios que a sociedade obtém
dos ecossistemas e que são fundamentais para o seu bem-estar. Para que este
framework possa ser utilizado na tomada de decisão, o primeiro passo é o seu
mapeamento. Esta dissertação mapeou qualitativamente o potencial de provisão de
oito SE para a cidade do Rio de Janeiro – controle de inundações, manutenção da
qualidade do ar, regulação climática, mitigação de tempestades e eventos extremos,
beleza cênica, religião e espiritualidade, recreação e turismo, e saúde física e
mental. O mapeamento foi realizado através de reclassificação de dados de uso e
cobertura do solo, definição de SE prioritários e entrevistas com especialistas. O
estudo constatou que houve aumento do percentual de área urbana e diminuição da
provisão de cinco SE em todas as regiões da cidade. O estudo também mapeou a
oferta e demanda de serviços ecossistêmicos culturais (SEC), com o objetivo de
identificar a relação dos habitantes da cidade com os ecossistemas locais a partir da
aplicação de questionário eletrônico. Verificou-se que os habitantes da Zona Sul e
Zona Oeste frequentam, preferencialmente, áreas próximas aos bairros onde moram
e, prioritariamente, praias. A Zona Norte é a região com maior percentual de área
urbana (82 por cento) e menor oferta de áreas naturais. Apesar da cidade contar com uma
enorme diversidade de ecossistemas, estes não estão distribuídos de maneira
equânime no território e há diferenças significativas tanto na oferta de áreas
naturais, quanto nas características socioeconômicas quando comparamos as cinco
grandes Áreas de Planejamento municipais. / [en] Ecosystem services (ES) are the benefits that society obtains from
ecosystems and are fundamental to human well-being. For this framework to be
used in decision making, the first step is mapping ES. This study mapped the
provision of eight ES for the city of Rio de Janeiro - flood control, air quality
maintenance, climate regulation, mitigation of storms and extreme events, scenic
beauty, religion and spirituality, recreation and tourism, and physical and mental
health. Mapping was accomplished through reclassification of land use and land
cover data, definition of priority ESs, and interviews with experts. The study found
that there was an increase in the percentage of urban area and a decrease in the
provision of five SEs in all regions of the city. The study also mapped the supply
and demand of cultural ecosystem services (CES), to identifying the relationship of
the city s inhabitants with local ecosystems through the application of an electronic
questionnaire. It was found that the inhabitants of the South Zone and West Zone
preferably frequent areas close to the neighborhoods and, as a priority, the beaches.
The North Zone is the region with the highest percentage of urban area (82 percent) and
the lowest offer of natural areas. Although the city has an enormous diversity of
ecosystems, these are not equally distributed in the territory and there are significant
differences both in the supply of natural areas and in socioeconomic characteristics
when we compare the five large municipal Planning Areas.

Denna studie syftar till att synliggöra och utforska vilka möjligheter och utmaningar som finns vid implementering av ekosystemtjänster istadsplanering. Studien bygger på Nacka kommuns arbete med ekosystemtjänster. Empiriskt har en intervjustudie genomförts med berördatjänstemän och ledande politiker kring kommunens praktiska arbete med att förhålla sig till och använda ekosystemtjänster i stadsplanering. Detempiriska materialet analyseras och sätt i relation till tidigare forskning inom frågan. Resultatet visar att det finns både möjligheter ochutmaningar i Nacka kommun med att implementera ekosystemtjänster i stadsplanering. Det framkommer att kommunikation, samverkan ochkunskap är tre viktiga faktorer för en lyckad implementering. För att kommunen ska ha en långsiktig stadsplanering där ekosystemtjänster spelaren viktig roll, krävs en kontinuerlig dialog mellan tjänstemän och politiker, liksom politisk enighet. Ett framträdande projekt är Grönytefaktornsom innefattar mestadels möjligheter med att integrera ekosystemtjänster i stadsplanering.

Oferta de serviços ecossistêmicos hídricos diante da conversão de paisagens savânicas em campos antrópicos / Water-related ecosystem services supply in the face of conversion of savanna landscapes into anthropic grasslandBitencourt, Augusto César D\'Avila 27 July 2017 (has links)
A perspectiva de elaborar planejamentos em áreas de floresta a partir da concepção de serviços ecossistêmicos, principalmente serviços hídricos, expandiu-se em muito pouco tempo, principalmente porque essa estratégia evidencia, claramente, como a perda desse sistema natural por atividades antrópicas pode causar perdas irreparáveis ao próprio bem-estar humano. Trabalhar planejamento ambiental sob esse enfoque exige a adoção de uma forte base teórica sobre serviços hídricos; um modelo que permita comparar paisagens em diferentes condições de uso e conservação de floresta; e clareza sobre o tipo de valoração empregado na identificação dos limites de perdas de floresta, de forma a não comprometer a oferta necessária desses serviços. Este estudo defende que no Cerrado do estado de São Paulo, em seus remanescentes caracterizados como sistemas florestados em áreas savânicas, é possível reconhecer a dependência direta entre quantidades de floresta, de usos humanos e de serviços hídricos em microbacias hidrográficas e, em meio disso, valorar a oferta desses serviços e comparar paisagens. Para fortalecer esse argumento foram selecionadas 10 unidades territoriais no estado de São Paulo com diferentes percentuais de cobertura florestal e campo antrópico. Em cada unidade foram obtidos dados de 13 parâmetros físico-químico-biológicos, que foram hierarquizados pelo algoritmo Random Forest de forma a aferir suas relações com a quantidade de floresta e formular índices de sete serviços ecossistêmicos hídricos. Os parâmetros que se mostraram mais adequados para monitoramento dos serviços hídricos frente aos ganhos de floresta, com grande peso hierárquico na formulação dos índices, foram oxigênio dissolvido, amônio e fósforo total. Os índices obtidos permitiram apontar que para a manutenção de 50% do potencial total dos sete serviços hídricos em paisagens com campos antrópicos são necessários pelo menos 20% de cobertura florestal, mas os melhores ganhos potenciais de serviços ocorreram a partir de 70% / The prospect of elaborating environmental planning in forest areas from the ecosystem services concept, especially water-related ecosystem services, has expanded greatly in a very short time, mainly because this strategy clearly demonstrate how the loss of this natural system by anthropic activities can cause irreparable losses to human well-being. Working with environmental planning under this approach requires the adoption of a strong theoretical basis on water-related ecosystem services; a model that allows to compare landscapes under different conditions of human use and forest conservation; and insight about the type of valuation used to recognize forest loss thresholds that must not be crossed, in order to do not compromise the necessary supply of these services. This study argues that in São Paulo state Cerrado (brazilian savanna), in its remnants characterized as forest systems in savanna areas, it is possible to recognize the direct dependence between forest quantities, human uses and water-related ecosystem services in catchments and, thereby, value the supply of these services and compare landscapes. To strengthen this argument, 10 territorial units were selected in São Paulo state with different percentages of forest and anthropic grasslands. In each unit, data were obtained from 13 physical-chemical-biological parameters, which were hierarchized by Random Forest algorithm in order to assess their relationships with forest quantity and formulate indexes of seven water-related ecosystem services. The most adequate parameters to monitor water-related ecosystem services in the face of forest gains with great hierarchical weight in the index formulation were dissolved oxygen, ammonia and total phosphorus. The obtained indexes allowed indicating that for the maintenance of 50% of the total potential of the seven water-related ecosystem services in landscapes with anthropic grasslands, more than 20% of forest cover is required, but the best potential gains of water-related ecosystem services occurred from 70% of forest cover

Development and Validation of a Landscape Metrics Based Approach for Standardized Landscape Assessment Considering Spatial Patterns / Entwicklung und Validierung eines auf Landschaftsstrukturmaßen basierenden Ansatzes zur standardisierten Landschaftsbewertung unter Berücksichtigung räumlicher MusterFrank, Susanne 20 August 2014 (has links) (PDF)
The presented dissertation entitled „Development and Validation of a Landscape Metrics Based Approach for Standardized Landscape Assessment Considering Spatial Patterns” addresses three main questions:
I. Which ecosystem services depend on landscape structure?
II. How can landscape metrics be used to achieve a standardized routine for assessing the impact of landscape structure on the hereon dependent ecosystem services?
III. How can regional planning benefit from the consideration of landscape structural effects on the provision of ecosystem services?
The PhD study was carried out in the context of the Climate Change adaptation project REGKLAM (funding code 01 LR 0802). The work package “Land Use” was conducted at the Institute of Soil Science and Site Ecology of the TU Dresden under the direction of Prof. Dr. Makeschin. The PhD study took place in the framework of a sub-work package of it, which was called “Integrated Land Use Assessment”. The aim of this sub-work package was the evaluation of Climate Change adaptation strategies at the landscape scale in a cross-sectoral manner. The ecosystem services concept was chosen as methodological framework for this purpose. Particular motivation of this PhD study was that landscape structural aspects are often not sufficiently considered in commonly used ecosystem services assessment approaches. A standardized assessment procedure regarding the impact of the composition and configuration of land use/ land cover types is not yet existent in contemporary planning approaches, neither in strategic environmental assessment. In my thesis, I developed in the period from 2010 to 2014 a methodological basis which addresses this challenge.
My thesis was realized as cumulative dissertation, which consists of three articles. These articles are published in peer-reviewed, ISI-listed international journals, whereas the third article still is in press.
The short introduction in chapter one gives information on the motivation and the structure of the thesis. In chapter two, the research hypothesis is formulated and scope and objectives are explained. Chapter three gives an overview of the history of landscape metrics, the state-of-the-art, and current research in topic. In chapter four, the model region, focus areas, and the methodological basis are described. The fifth chapter summarizes results of the three articles (Frank et al. 2012, 2013, in press). Discussions in chapter six critically reflect the methodology and identify limitations, strengths, and its contribution to regional planning and to decision-making. Furthermore, some suggestions for extending the approach to other ecosystem services, especially regulating services, are made and perspectives towards different research questions are shown. Chapter seven summarizes the main outcomes of the PhD study.
The central output of the dissertation is a module of GISCAME, a land use change impact assessment platform for supporting regional planning. The landscape metrics based ecosystem services assessment approach facilitates calculation, combination, and interpretation of a choice of landscape metrics and, hence, the evaluation of the impact of composition and configuration of land use patterns on ecosystem services. I selected eleven focus areas in the planning region “Upper Elbe Valley/Eastern Ore Mountains” to demonstrate the application and validation of the landscape metrics based approach that I propose in my dissertation. With these use cases, I show that the landscape structure significantly influences the provision of the ecosystem services ecological integrity and landscape aesthetics.
Within the first use case I could demonstrate that the afforestation planning can be enhanced by including landscape metrics in the planning process. Actual priority areas for afforestation do not contribute to ecological integrity at the regional scale. Landscape fragmentation, habitat connectivity, and landscape diversity must be taken into account in order to identify most efficient priority areas for afforestation in terms of enhancing ecological integrity. The second use case focused on the question, how landscape structure influences scenic beauty. By means of a survey, I performed a comparison between the landscape metrics based approach and landscape perception of 153 respondents. This test underpinned my assumption that a landscape metrics based routine allows conclusions on the value of landscape aesthetics. The third use case gives practical advice in the current planning challenge about how to enhance water erosion protection planning in the context of Climate Change. Here, I demonstrated that not only land use change in preferential water erosion paths, but especially the change of management strategies combined with an improvement of landscape structure have the capacity to reduce water erosion potential by 92 %.
The results show that it is of great importance to consider landscape structural aspects in current and future regional planning questions because additional, relevant planning information becomes tangible. The comparison of the presented method with other landscape metrics based approaches for ecosystem services assessment shows that the interpretation of the landscape metric values in the GISCAME platform module goes one step further towards usability for planning support: its transparency, spatial transferability, and flexibility are the main strengths of the approach. However, there is a clear need to involve the impact of landscape structure aspects also regarding other ecosystem services. / Die vorgelegte Dissertation mit dem Titel „Entwicklung und Validierung eines auf Landschaftsstrukturmaßen basierten Ansatzes zur standardisierten Landschaftsbewertung unter Berücksichtigung räumlicher Muster“ behandelt die drei Hauptfragen
I. Welche Ökosystemdienstleistungen hängen von der Landschaftsstruktur ab?
II. Wie können Landschaftsstrukturmaße genutzt werden, um ein standardisiertes Bewertungsverfahren dieser abhängigen Ökosystemdienstleistungen zu ermöglichen?
III. Wie kann die Regionalplanung von der Berücksichtigung der Effekte von Landschaftsstruktur auf die Bereitstellung von Ökosystemdienstleistungen profitieren?
Die Promotions-Studie wurde im Rahmen des Klimawandel-Anpassungs-Projektes REGKLAM (Förderkennzeichen 01 LR 0802) durchgeführt. Das Arbeitspaket „Landnutzung“ wurde am Institut für Bodenkunde und Standortslehre der TU Dresden unter Leitung von Prof. Dr. Makeschin bearbeitet. Die Promotions-Studie erfolgte im Rahmen des Teil-Arbeitstaktes „Integrierte Landnutzungsbewertung“. Ziel dieses Teil-Arbeitspaketes war die Bewertung von Klimawandel-Anpassungs-Strategien auf Landschaftsebene in Sektor-übergreifender Weise. Zu diesem Zweck wurde das Ökosystemdienstleistungskonzept als methodischer Rahmen gewählt. Der spezielle Anlass dieser Promotion-Studie war, dass landschaftsstrukturelle Aspekte in gebräuchlichen Ökosystemdienstleistungs-Bewertungsansätzen oft ungenügend berücksichtigt sind. Ein standardisiertes Bewertungsverfahren des Einflusses von Zusammensetzung und Anordnung von Landnutzungs-/Landbedeckungstypen existiert weder in aktuellen Planungsansätzen noch in Umweltverträglichkeitsprüfungen. In meiner Dissertation entwickelte ich im Zeitraum von 2010 bis 2014 eine methodische Grundlage, welche diese Herausforderung angeht.
Meine Promotion wurde als kumulative Dissertation, welche aus drei Artikeln besteht, umgesetzt. Diese Artikel wurden in begutachteten, ISI-gelisteten, internationalen Journalen veröffentlicht, wobei sich das dritte aktuell im Druck befindet.
Die kurze Einleitung im ersten Kapitel informiert über die Beweggründe und die Struktur der Dissertation. Im zweiten Kapitel ist die Forschungshypothese formuliert sowie Geltungsbereich und Zeile erläutert. Kapitel drei gibt einen Überblick über die Geschichte der Landschaftsstrukturmaße, den aktuellen Forschungsstand und aktuelle Forschungsfelder. Im vierten Kapitel sind die Modellregion, die Fallstudien-Gebiete, sowie methodische Grundlagen beschrieben. Das fünfte Kapitel fasst die Ergebnisse der drei Artikel (Frank et al. 2012, 2013, im Druck) zusammen. Diskussionen in Kapitel sechs reflektieren die Methodik kritisch und identifizieren ihre Grenzen und Stärken sowie den Beitrag der Ergebnisse zu Regionalplanung und Entscheidungsfindung. Darüber hinaus werden einige Empfehlungen zur Erweiterung des Ansatzes für weitere Ökosystemdienstleistungen, insbesondere regulierende Leistungen, getroffen und Perspektiven zur Anwendung für andere Forschungsfragen werden aufgezeigt. Kapitel sieben fasst schließlich die wichtigsten Ergebnisse der Promotions-Studie zusammen.
Das zentrale Ergebnis der Dissertation ist eine Erweiterung des Entscheidungsunterstützungs-Werkzeuges GISCAME. Der auf Landschaftsstrukturmaßen basierende Ökosystemdienstleistungs-Bewertungsansatz ermöglicht die Berechnung, Kombination und Interpretation einer Auswahl von Landschaftsstrukturmaßen und somit die Bewertung des Einflusses von Zusammensetzung und Anordnung von Landnutzungsmustern auf Ökosystemdienstleistungen. Ich wählte elf Fokusgebiete in der Planungsregion „Oberes Elbtal/Osterzgebirge“ aus um die Anwendung und Validierung des auf Landschaftsstrukturmaßen basierenden Ansatzes, den ich in der Dissertation vorschlage, zu demonstrieren. Mittels dieser Anwendungsfälle zeige ich, dass die Landschaftsstruktur die Bereitstellung der Ökosystemdienstleistungen ökologische Integrität und Landschaftsästhetik erheblich beeinflusst.
Im ersten Anwendungsfall konnte ich zeigen, dass die Aufforstungsplanung durch die Einbeziehung von Landschaftsstrukturmaßen in den Planungsprozess verbessert werden kann. Vorranggebiete für Waldmehrung in ihrer derzeitigen Form tragen nicht zur ökologischen Integrität auf der regionalen Ebene bei. Landschaftszerschneidung, Biotopverbund und Landschaftsdiversität müssen vermehrt beachtet werden, um Vorranggebiete für Waldmehrung für eine Verbesserung der ökologischen Intaktheit effizienter anzuordnen. Der zweite Anwendungsfall richtete sich auf die Frage, wie Landschaftsstruktur die Landschaftsästhetik beeinflusst. Mithilfe einer Befragung verglich ich den auf Landschaftsstrukurmaßen basierenden Ansatz mit der Landschaftswahrnehmung von 153 Befragten. Dieser Test untermauerte meine Annahme, dass das auf Landschaftsstrukurmaßen basierende Vorgehen Rückschlüsse auf den ästhetischen Wert einer Landschaft zulässt. Der dritte Anwendungsfall gibt praktische Hinweise bezüglich der aktuellen Planungs-Herausforderung, wie Erosionsschutzplanung im Kontext des Klimawandels verbesset werden kann. In diesem Fall konnte ich zeigen, dass nicht nur Landnutzungsänderungen in präferenziellen Abflussbahnen, sondern insbesondere eine Änderung der Bodenbearbeitungsstrategie in Kombination mit verbesserter Landschaftsstruktur das Potential hat, die potentielle Wassererosion um 92 % zu reduzieren.
Die Ergebnisse zeigen, dass es von großer Bedeutung ist, landschaftsstrukturelle Aspekte in aktuellen und zukünftigen Planungsfragen zu berücksichtigen, da somit zusätzliche, maßgebliche Informationen greifbar werden. Der Vergleich der vorliegenden Methodik mit anderen Ansätzen, die Landschaftsstrukturmaße nutzen um Ökosystemdienstleistungen zu bewerten, zeigt, dass die automatisierte Interpretation der Landschaftsstrukturmaße mittels des neuen Moduls in GISCAME einen Schritt in Richtung Nützlichkeit für Planungsunterstützung geht: Transparenz, räumliche Übertragbarkeit und Flexibilität sind weitere Stärken des Ansatzes. Jedoch gibt es eindeutig den Bedarf den Einfluss von Landschaftsstruktur auf weitere Ökosystemdienstleistungen einzubeziehen.

Oferta de serviços ecossistêmicos hídricos diante da conversão de paisagens savânicas em campos antrópicos / Water-related ecosystem services supply in the face of conversion of savanna landscapes into anthropic grasslandAugusto César D\'Avila Bitencourt 27 July 2017 (has links)

Modelagem e valoração dos serviços ambientais hidrológicos na recuperação da vegetação no Ribeirão das Posses, Extrema, MG / Modeling and valuation of hydrological environmental services in the recovery of vegetation in Ribeirão das Posses, Extrema, MGSandra Isay Saad 10 March 2016 (has links)
Questões ambientais e sócio-econômicas nem sempre coexistem de forma conciliada, o que pode opor a conservação da biodiversidade, a regulação climática, a produção e qua¬li¬da¬de da água, com outros fatores como a produção de energia, alimentos e fibras, e a geração de empregos. No Brasil, o código florestal prescreve as Áreas de Preservação Permanente como forma de garantir a manutenção dos Serviços Ambientais (SA), e os projetos de Pagamento de Serviços Ambientais (PSA) estão surgindo como forma de recompensar os provedores de SA, como o Projeto Conservador das Águas, a primeira experiência municipal brasileira, em andamento no Município de Extrema, MG. Apesar dos esforços, ainda são escassos os estudos que quantifiquem os benefícios econômicos dos serviços ambientais, fundamental para que estes sejam incluídos nas tomadas de decisões. O objetivo do trabalho foi quantificar e valorar os Serviços Ambientais hidrológicos da recuperação da vegetação, na sub-bacia do Ribeirão das Posses, em Extrema, através da modelagem ambiental. Utilizando o modelo InVEST (Integrated Valuation of Environmental Services and Tradeoffs) foram simuladas a vazão e o fluxo de sedimentos em um cenário anterior e posterior ao Projeto Conservador das Águas, um cenário sem práticas de conservação (Antropizado), e em cenários que priorizassem o reflorestamento ao longo das margens dos rios (reflorestamento ripário) ou nas encostas (reflorestamento das áreas íngremes). Os Serviços Ambientais foram estimados a partir do custo evitado da redução do tratamento de água e dragagem (custos off-site) e na erosão (custos on-site), em função da diferença entre os cenários, e foram comparados com o Pagamento por Serviços Ambientais e o custo de oportunidade, equivalente aos rendimentos da pecuária extensiva. Verificou-se que as estradas geraram 29% da perda de solos na sub-bacia, e as barraginhas, uma das práticas conservacionistas adotadas pelo projeto, diminuíram em 4% os sedimentos na foz da sub-bacia, e o reflorestamento de espécies nativas em 5%. Juntas, as duas práticas contribuíram para 9% de redução. A redução do fluxo de sedimentos do Pós-Projeto em relação ao cenário Antropizado foi de 40%. O reflorestamento ripário foi mais eficiente na redução de fluxo de sedimentos do que o reflorestamento das áreas íngremes e gerou maior redução nos custos de tratamento de água e de dragagem. Enquanto um reflorestamento ripário de apenas 5 m reduziu em 23% o fluxo de sedimentos, um reflorestamento nas áreas íngremes com a mesma área de floresta (áreas com declividade acima de 60%) reduziu o fluxo de sedimentos em 2%. Para um reflorestamento ripário de 30 m, o mesmo foi reduzido em 50%. Por outro lado, o reflorestamento das áreas íngremes foi mais eficiente na redução da perda de solos, e portanto, obteve maior redução dos custos on-site, pela redução dos prejuízos causados pela erosão. Os resultados mostram a importância de projetos como o Conservador das Águas, não só na melhoria das condições ambientais, mas principalmente na conservação de florestas nativas. Os pequenos agricultores são uns dos principais beneficiários devido à melhoria das condições sociais e ambientais, embora não sejam os únicos, uma vez que os benefícios vão além dos limites da sub-bacia, e acreditamos que os esforços para a preservação devem ser com¬par¬ti¬lha-dos pelos beneficiários indiretos, que no caso da sub-bacia do Ribeirão das Posses, seriam os usuários da água do Sistema Cantareira. A nossa sugestão para esta contribuição é de pelo menos 28% do Pagamento por Serviços Ambientais por área preservada. / Environmental and socioeconomic issues not always coexist in a reconciled manner, which may oppose biodiversity conservation, climate regulation, water quality and production, to other factors such as energy production, food and fiber, and job creation. In Brazil, the Forest Code prescribes the Permanent Preservation Areas in order to guarantee the maintenance of Environmental Services (ES), and the Payment for Environmental Services project (PES) are emerging as a way to reward the providers of ES, as Conservador das Águas project, the first Brazilian municipal initiative, underway in Extrema Municipality. Despite the efforts, there are few studies that quantify the economic benefits of ecosystem services essential for them to be part of decision-making process. The objective of this work was to quantify and assess the hydrological Environmental Services in the recovery of vegetation in Posses subbasin in Extrema, through environmental modeling. Using InVEST model (Integrated Valuation of Environmental Services and Tradeoffs) we simulated sediment and streamflow in a scenario before Conservador das Águas project (Pre-Project), after (Post-Project), another with no soil conservation practices (Anthropized), and others which prioritize reforestation of riparian areas (riparian reforestation) or in slopes (reforestation of steep areas). The Environmental Services were estimated based on the avoided cost of reducing water treatment and dredging (off-site costs) and erosion (on-site costs), as functions of the difference between scenarios, and they were compared to the Payment for Environmental Services and the opportunity cost, equivalent to the extensive livestock income. It was found that the roads contributed to 29% of the total soil loss in the subbasin, and barraginhas, one of the conservation practices adopted by the project, decreased sediment flow in the river mouth by 4%, and reforestation of native species by 5%. Together, the two practices contributed to a reduction in 9%. The reduction of sediments flow in Post-Project scenario in relation to Anthropized was of 40%. Riparian reforestation was more efficient in the reduction of sediment flow than the reforestation of steep areas, what caused greater reduction in the costs of water treatment and dredging. While a 5 m riparian reforestation reduced sediment flow by 23%, reforestation in steep areas with the same area of forest (areas with slope above 60%) reduced sediment flow by 2%. For a 30 m of riparian strip of reforestation, it was reduced by 50%. On the other hand, reforestation of steep areas was more efficient in reducing soil loss, and so it presented greater reduction in on-site costs by reducing the losses caused by erosion. Results showed the importance of projects such as the Conservador das Águas, not only in the improvement of environmental conditions, but mainly in the conservation of native forests. The main beneficiaries of these projects are small farmers by improving social and environmental conditions, but the benefits go beyond the subbasin boundaries, and we believe that efforts to preserve must be shared by indirect beneficiaries, which in the case of Posses subbasin are the users of water from the Cantareira System. Our suggestion for this contribution is at least 28% of Payment for Environmental Services by preserved area.

Empowering the Steel Industry as a Stakeholder : Environmental Management and Communication through a Social-Ecological ApproachBerg, Alicia January 2013 (has links)
This paper explores a case study of a Swedish tool steel company undergoing a transition from traditional environmental management practices to an enterprise identifying its place as part of a social-ecological system. The Corporate Ecosystem Services Review (ESR) was utilized by the company to begin this process by focusing on ecosystem services to determine how an ESR approach contributes to environmental management in practice. What resulted moved beyond the ESR to a tailored methodology, the internalization of a systems perspective, and a proposed new environmental management system. The results of the study provide a concrete, effective method for internalizing a systems perspective through a focus on ecosystems and presents a case for further analysis into what made it successful. It also provides an example of translating theory into practice, illustrating how a company can engage in sustainable development by valuing and managing the resilience of social-ecological systems through identifying their place in that system. The value of the results can be high for the case study company as well as for business in general.

Modelagem e valoração dos serviços ambientais hidrológicos na recuperação da vegetação no Ribeirão das Posses, Extrema, MG / Modeling and valuation of hydrological environmental services in the recovery of vegetation in Ribeirão das Posses, Extrema, MGSaad, Sandra Isay 10 March 2016 (has links)
Questões ambientais e sócio-econômicas nem sempre coexistem de forma conciliada, o que pode opor a conservação da biodiversidade, a regulação climática, a produção e qua¬li¬da¬de da água, com outros fatores como a produção de energia, alimentos e fibras, e a geração de empregos. No Brasil, o código florestal prescreve as Áreas de Preservação Permanente como forma de garantir a manutenção dos Serviços Ambientais (SA), e os projetos de Pagamento de Serviços Ambientais (PSA) estão surgindo como forma de recompensar os provedores de SA, como o Projeto Conservador das Águas, a primeira experiência municipal brasileira, em andamento no Município de Extrema, MG. Apesar dos esforços, ainda são escassos os estudos que quantifiquem os benefícios econômicos dos serviços ambientais, fundamental para que estes sejam incluídos nas tomadas de decisões. O objetivo do trabalho foi quantificar e valorar os Serviços Ambientais hidrológicos da recuperação da vegetação, na sub-bacia do Ribeirão das Posses, em Extrema, através da modelagem ambiental. Utilizando o modelo InVEST (Integrated Valuation of Environmental Services and Tradeoffs) foram simuladas a vazão e o fluxo de sedimentos em um cenário anterior e posterior ao Projeto Conservador das Águas, um cenário sem práticas de conservação (Antropizado), e em cenários que priorizassem o reflorestamento ao longo das margens dos rios (reflorestamento ripário) ou nas encostas (reflorestamento das áreas íngremes). Os Serviços Ambientais foram estimados a partir do custo evitado da redução do tratamento de água e dragagem (custos off-site) e na erosão (custos on-site), em função da diferença entre os cenários, e foram comparados com o Pagamento por Serviços Ambientais e o custo de oportunidade, equivalente aos rendimentos da pecuária extensiva. Verificou-se que as estradas geraram 29% da perda de solos na sub-bacia, e as barraginhas, uma das práticas conservacionistas adotadas pelo projeto, diminuíram em 4% os sedimentos na foz da sub-bacia, e o reflorestamento de espécies nativas em 5%. Juntas, as duas práticas contribuíram para 9% de redução. A redução do fluxo de sedimentos do Pós-Projeto em relação ao cenário Antropizado foi de 40%. O reflorestamento ripário foi mais eficiente na redução de fluxo de sedimentos do que o reflorestamento das áreas íngremes e gerou maior redução nos custos de tratamento de água e de dragagem. Enquanto um reflorestamento ripário de apenas 5 m reduziu em 23% o fluxo de sedimentos, um reflorestamento nas áreas íngremes com a mesma área de floresta (áreas com declividade acima de 60%) reduziu o fluxo de sedimentos em 2%. Para um reflorestamento ripário de 30 m, o mesmo foi reduzido em 50%. Por outro lado, o reflorestamento das áreas íngremes foi mais eficiente na redução da perda de solos, e portanto, obteve maior redução dos custos on-site, pela redução dos prejuízos causados pela erosão. Os resultados mostram a importância de projetos como o Conservador das Águas, não só na melhoria das condições ambientais, mas principalmente na conservação de florestas nativas. Os pequenos agricultores são uns dos principais beneficiários devido à melhoria das condições sociais e ambientais, embora não sejam os únicos, uma vez que os benefícios vão além dos limites da sub-bacia, e acreditamos que os esforços para a preservação devem ser com¬par¬ti¬lha-dos pelos beneficiários indiretos, que no caso da sub-bacia do Ribeirão das Posses, seriam os usuários da água do Sistema Cantareira. A nossa sugestão para esta contribuição é de pelo menos 28% do Pagamento por Serviços Ambientais por área preservada. / Environmental and socioeconomic issues not always coexist in a reconciled manner, which may oppose biodiversity conservation, climate regulation, water quality and production, to other factors such as energy production, food and fiber, and job creation. In Brazil, the Forest Code prescribes the Permanent Preservation Areas in order to guarantee the maintenance of Environmental Services (ES), and the Payment for Environmental Services project (PES) are emerging as a way to reward the providers of ES, as Conservador das Águas project, the first Brazilian municipal initiative, underway in Extrema Municipality. Despite the efforts, there are few studies that quantify the economic benefits of ecosystem services essential for them to be part of decision-making process. The objective of this work was to quantify and assess the hydrological Environmental Services in the recovery of vegetation in Posses subbasin in Extrema, through environmental modeling. Using InVEST model (Integrated Valuation of Environmental Services and Tradeoffs) we simulated sediment and streamflow in a scenario before Conservador das Águas project (Pre-Project), after (Post-Project), another with no soil conservation practices (Anthropized), and others which prioritize reforestation of riparian areas (riparian reforestation) or in slopes (reforestation of steep areas). The Environmental Services were estimated based on the avoided cost of reducing water treatment and dredging (off-site costs) and erosion (on-site costs), as functions of the difference between scenarios, and they were compared to the Payment for Environmental Services and the opportunity cost, equivalent to the extensive livestock income. It was found that the roads contributed to 29% of the total soil loss in the subbasin, and barraginhas, one of the conservation practices adopted by the project, decreased sediment flow in the river mouth by 4%, and reforestation of native species by 5%. Together, the two practices contributed to a reduction in 9%. The reduction of sediments flow in Post-Project scenario in relation to Anthropized was of 40%. Riparian reforestation was more efficient in the reduction of sediment flow than the reforestation of steep areas, what caused greater reduction in the costs of water treatment and dredging. While a 5 m riparian reforestation reduced sediment flow by 23%, reforestation in steep areas with the same area of forest (areas with slope above 60%) reduced sediment flow by 2%. For a 30 m of riparian strip of reforestation, it was reduced by 50%. On the other hand, reforestation of steep areas was more efficient in reducing soil loss, and so it presented greater reduction in on-site costs by reducing the losses caused by erosion. Results showed the importance of projects such as the Conservador das Águas, not only in the improvement of environmental conditions, but mainly in the conservation of native forests. The main beneficiaries of these projects are small farmers by improving social and environmental conditions, but the benefits go beyond the subbasin boundaries, and we believe that efforts to preserve must be shared by indirect beneficiaries, which in the case of Posses subbasin are the users of water from the Cantareira System. Our suggestion for this contribution is at least 28% of Payment for Environmental Services by preserved area.

Development and Validation of a Landscape Metrics Based Approach for Standardized Landscape Assessment Considering Spatial PatternsFrank, Susanne 17 July 2014 (has links)
The presented dissertation entitled „Development and Validation of a Landscape Metrics Based Approach for Standardized Landscape Assessment Considering Spatial Patterns” addresses three main questions:
I. Which ecosystem services depend on landscape structure?
II. How can landscape metrics be used to achieve a standardized routine for assessing the impact of landscape structure on the hereon dependent ecosystem services?
III. How can regional planning benefit from the consideration of landscape structural effects on the provision of ecosystem services?
The PhD study was carried out in the context of the Climate Change adaptation project REGKLAM (funding code 01 LR 0802). The work package “Land Use” was conducted at the Institute of Soil Science and Site Ecology of the TU Dresden under the direction of Prof. Dr. Makeschin. The PhD study took place in the framework of a sub-work package of it, which was called “Integrated Land Use Assessment”. The aim of this sub-work package was the evaluation of Climate Change adaptation strategies at the landscape scale in a cross-sectoral manner. The ecosystem services concept was chosen as methodological framework for this purpose. Particular motivation of this PhD study was that landscape structural aspects are often not sufficiently considered in commonly used ecosystem services assessment approaches. A standardized assessment procedure regarding the impact of the composition and configuration of land use/ land cover types is not yet existent in contemporary planning approaches, neither in strategic environmental assessment. In my thesis, I developed in the period from 2010 to 2014 a methodological basis which addresses this challenge.
My thesis was realized as cumulative dissertation, which consists of three articles. These articles are published in peer-reviewed, ISI-listed international journals, whereas the third article still is in press.
The short introduction in chapter one gives information on the motivation and the structure of the thesis. In chapter two, the research hypothesis is formulated and scope and objectives are explained. Chapter three gives an overview of the history of landscape metrics, the state-of-the-art, and current research in topic. In chapter four, the model region, focus areas, and the methodological basis are described. The fifth chapter summarizes results of the three articles (Frank et al. 2012, 2013, in press). Discussions in chapter six critically reflect the methodology and identify limitations, strengths, and its contribution to regional planning and to decision-making. Furthermore, some suggestions for extending the approach to other ecosystem services, especially regulating services, are made and perspectives towards different research questions are shown. Chapter seven summarizes the main outcomes of the PhD study.
The central output of the dissertation is a module of GISCAME, a land use change impact assessment platform for supporting regional planning. The landscape metrics based ecosystem services assessment approach facilitates calculation, combination, and interpretation of a choice of landscape metrics and, hence, the evaluation of the impact of composition and configuration of land use patterns on ecosystem services. I selected eleven focus areas in the planning region “Upper Elbe Valley/Eastern Ore Mountains” to demonstrate the application and validation of the landscape metrics based approach that I propose in my dissertation. With these use cases, I show that the landscape structure significantly influences the provision of the ecosystem services ecological integrity and landscape aesthetics.
Within the first use case I could demonstrate that the afforestation planning can be enhanced by including landscape metrics in the planning process. Actual priority areas for afforestation do not contribute to ecological integrity at the regional scale. Landscape fragmentation, habitat connectivity, and landscape diversity must be taken into account in order to identify most efficient priority areas for afforestation in terms of enhancing ecological integrity. The second use case focused on the question, how landscape structure influences scenic beauty. By means of a survey, I performed a comparison between the landscape metrics based approach and landscape perception of 153 respondents. This test underpinned my assumption that a landscape metrics based routine allows conclusions on the value of landscape aesthetics. The third use case gives practical advice in the current planning challenge about how to enhance water erosion protection planning in the context of Climate Change. Here, I demonstrated that not only land use change in preferential water erosion paths, but especially the change of management strategies combined with an improvement of landscape structure have the capacity to reduce water erosion potential by 92 %.
The results show that it is of great importance to consider landscape structural aspects in current and future regional planning questions because additional, relevant planning information becomes tangible. The comparison of the presented method with other landscape metrics based approaches for ecosystem services assessment shows that the interpretation of the landscape metric values in the GISCAME platform module goes one step further towards usability for planning support: its transparency, spatial transferability, and flexibility are the main strengths of the approach. However, there is a clear need to involve the impact of landscape structure aspects also regarding other ecosystem services.:Contents

Appendices 33 / Die vorgelegte Dissertation mit dem Titel „Entwicklung und Validierung eines auf Landschaftsstrukturmaßen basierten Ansatzes zur standardisierten Landschaftsbewertung unter Berücksichtigung räumlicher Muster“ behandelt die drei Hauptfragen
I. Welche Ökosystemdienstleistungen hängen von der Landschaftsstruktur ab?
II. Wie können Landschaftsstrukturmaße genutzt werden, um ein standardisiertes Bewertungsverfahren dieser abhängigen Ökosystemdienstleistungen zu ermöglichen?
III. Wie kann die Regionalplanung von der Berücksichtigung der Effekte von Landschaftsstruktur auf die Bereitstellung von Ökosystemdienstleistungen profitieren?
Die Promotions-Studie wurde im Rahmen des Klimawandel-Anpassungs-Projektes REGKLAM (Förderkennzeichen 01 LR 0802) durchgeführt. Das Arbeitspaket „Landnutzung“ wurde am Institut für Bodenkunde und Standortslehre der TU Dresden unter Leitung von Prof. Dr. Makeschin bearbeitet. Die Promotions-Studie erfolgte im Rahmen des Teil-Arbeitstaktes „Integrierte Landnutzungsbewertung“. Ziel dieses Teil-Arbeitspaketes war die Bewertung von Klimawandel-Anpassungs-Strategien auf Landschaftsebene in Sektor-übergreifender Weise. Zu diesem Zweck wurde das Ökosystemdienstleistungskonzept als methodischer Rahmen gewählt. Der spezielle Anlass dieser Promotion-Studie war, dass landschaftsstrukturelle Aspekte in gebräuchlichen Ökosystemdienstleistungs-Bewertungsansätzen oft ungenügend berücksichtigt sind. Ein standardisiertes Bewertungsverfahren des Einflusses von Zusammensetzung und Anordnung von Landnutzungs-/Landbedeckungstypen existiert weder in aktuellen Planungsansätzen noch in Umweltverträglichkeitsprüfungen. In meiner Dissertation entwickelte ich im Zeitraum von 2010 bis 2014 eine methodische Grundlage, welche diese Herausforderung angeht.
Meine Promotion wurde als kumulative Dissertation, welche aus drei Artikeln besteht, umgesetzt. Diese Artikel wurden in begutachteten, ISI-gelisteten, internationalen Journalen veröffentlicht, wobei sich das dritte aktuell im Druck befindet.
Die kurze Einleitung im ersten Kapitel informiert über die Beweggründe und die Struktur der Dissertation. Im zweiten Kapitel ist die Forschungshypothese formuliert sowie Geltungsbereich und Zeile erläutert. Kapitel drei gibt einen Überblick über die Geschichte der Landschaftsstrukturmaße, den aktuellen Forschungsstand und aktuelle Forschungsfelder. Im vierten Kapitel sind die Modellregion, die Fallstudien-Gebiete, sowie methodische Grundlagen beschrieben. Das fünfte Kapitel fasst die Ergebnisse der drei Artikel (Frank et al. 2012, 2013, im Druck) zusammen. Diskussionen in Kapitel sechs reflektieren die Methodik kritisch und identifizieren ihre Grenzen und Stärken sowie den Beitrag der Ergebnisse zu Regionalplanung und Entscheidungsfindung. Darüber hinaus werden einige Empfehlungen zur Erweiterung des Ansatzes für weitere Ökosystemdienstleistungen, insbesondere regulierende Leistungen, getroffen und Perspektiven zur Anwendung für andere Forschungsfragen werden aufgezeigt. Kapitel sieben fasst schließlich die wichtigsten Ergebnisse der Promotions-Studie zusammen.
Das zentrale Ergebnis der Dissertation ist eine Erweiterung des Entscheidungsunterstützungs-Werkzeuges GISCAME. Der auf Landschaftsstrukturmaßen basierende Ökosystemdienstleistungs-Bewertungsansatz ermöglicht die Berechnung, Kombination und Interpretation einer Auswahl von Landschaftsstrukturmaßen und somit die Bewertung des Einflusses von Zusammensetzung und Anordnung von Landnutzungsmustern auf Ökosystemdienstleistungen. Ich wählte elf Fokusgebiete in der Planungsregion „Oberes Elbtal/Osterzgebirge“ aus um die Anwendung und Validierung des auf Landschaftsstrukturmaßen basierenden Ansatzes, den ich in der Dissertation vorschlage, zu demonstrieren. Mittels dieser Anwendungsfälle zeige ich, dass die Landschaftsstruktur die Bereitstellung der Ökosystemdienstleistungen ökologische Integrität und Landschaftsästhetik erheblich beeinflusst.
Im ersten Anwendungsfall konnte ich zeigen, dass die Aufforstungsplanung durch die Einbeziehung von Landschaftsstrukturmaßen in den Planungsprozess verbessert werden kann. Vorranggebiete für Waldmehrung in ihrer derzeitigen Form tragen nicht zur ökologischen Integrität auf der regionalen Ebene bei. Landschaftszerschneidung, Biotopverbund und Landschaftsdiversität müssen vermehrt beachtet werden, um Vorranggebiete für Waldmehrung für eine Verbesserung der ökologischen Intaktheit effizienter anzuordnen. Der zweite Anwendungsfall richtete sich auf die Frage, wie Landschaftsstruktur die Landschaftsästhetik beeinflusst. Mithilfe einer Befragung verglich ich den auf Landschaftsstrukurmaßen basierenden Ansatz mit der Landschaftswahrnehmung von 153 Befragten. Dieser Test untermauerte meine Annahme, dass das auf Landschaftsstrukurmaßen basierende Vorgehen Rückschlüsse auf den ästhetischen Wert einer Landschaft zulässt. Der dritte Anwendungsfall gibt praktische Hinweise bezüglich der aktuellen Planungs-Herausforderung, wie Erosionsschutzplanung im Kontext des Klimawandels verbesset werden kann. In diesem Fall konnte ich zeigen, dass nicht nur Landnutzungsänderungen in präferenziellen Abflussbahnen, sondern insbesondere eine Änderung der Bodenbearbeitungsstrategie in Kombination mit verbesserter Landschaftsstruktur das Potential hat, die potentielle Wassererosion um 92 % zu reduzieren.
Die Ergebnisse zeigen, dass es von großer Bedeutung ist, landschaftsstrukturelle Aspekte in aktuellen und zukünftigen Planungsfragen zu berücksichtigen, da somit zusätzliche, maßgebliche Informationen greifbar werden. Der Vergleich der vorliegenden Methodik mit anderen Ansätzen, die Landschaftsstrukturmaße nutzen um Ökosystemdienstleistungen zu bewerten, zeigt, dass die automatisierte Interpretation der Landschaftsstrukturmaße mittels des neuen Moduls in GISCAME einen Schritt in Richtung Nützlichkeit für Planungsunterstützung geht: Transparenz, räumliche Übertragbarkeit und Flexibilität sind weitere Stärken des Ansatzes. Jedoch gibt es eindeutig den Bedarf den Einfluss von Landschaftsstruktur auf weitere Ökosystemdienstleistungen einzubeziehen.:Contents
