Previous issue date: 2011-03-25 / Financiadora de Estudos e Projetos / The approaches of socio-ecological systems, resilience, and adaptive management suggest new forest governance arrangements that include the participation of marginalized rural people in territorial management. These approaches require efforts of scientists and managers to deal with local knowledge and with the social institutions that govern resource access and use by these people. This research was conducted in two communities of the Lower Madeira River (São Carlos and Cuniã) and the objectives were: (i) to characterize the Brazil nut Bertholletia excelsa (Humb. & Bonpl.) harvest based on harvest practices and local knowledge; (ii) to characterize the official land tenure and the customary property rights regimes in the harvest areas within and around the protected areas where co-management between government and local communities is officially assumed; (iii) to determine whether there are discrepancies between official land tenure and customary property rights regimes in those areas; and (iv) to verify the influence of customary property rights regimes on specie's management, and which regime or regime arrangements are more likely to promote the conservation of the harvest areas and the species. Qualitative and ethnographic methods were used with semi-structured and open-ended questionnaires, participatory observation, and mapping with Brazil nut harvesters from the two communities and other stakeholders. The data were interpreted from the perspective of ethnoecology ("etnoecologia abrangente"), human ecology and property rights regimes. The results suggest that: (i) the existing local knowledge in the region is extensive and driven by environmental feedbacks and therefore should be considered for adaptive comanagement; (ii) the organization and dynamics in the harvest areas are complex and differ from the official land tenure; (iii) the management practices that contribute to conservation of B. excelsa are more likely to remain in property regime arrangements between state and community, since these regimes have less conflicts and uncertainty in relation to harvest areas access and use. / A visão dos sistemas socioecológicos como resilientes e cíclicos incita o manejo adaptativo e novos arranjos de governança sobre os recursos florestais que incluem a participação das populações rurais marginalizadas na gestão territorial. Essa abordagem requer esforços de cientistas e gestores para lidar com os conhecimentos locais e visão de mundo desses povos, incluindo o reconhecimento das instituições sociais que regem o acesso e uso à esses recursos. A presente pesquisa foi realizada nas comunidades de São Carlos e Cuniã, no Baixo Rio Madeira e pretendeu: (i) fazer uma caracterização das práticas e conhecimentos locais relacionados a atividade extrativista da castanha-do- Brasil Bertholetia excelsa (Humb. & Bonpl.); (ii) caracterizar a situação fundiária oficial e os regimes de direito de propriedade vigentes em áreas de coleta da espécie dentro e no entorno de áreas florestais protegidas que oficialmente assumem a gestão compartilhada do governo com a comunidade; (iii) verificar se existem discrepâncias entre situação fundiária oficial e os regimes de direito de propriedade vigentes nessas áreas; (iv) verificar se existe influência dos regimes de direito de propriedade no manejo da espécie e qual regime ou combinação de regimes é mais propício para a promoção da conservação de suas áreas. Foi feito um trabalho qualitativo e etnográfico- com questionários semi-estruturados e abertos, observações participantes e elaboração de mapas com extrativistas de castanha-do-Brasil das duas comunidades e stakeholders. Os dados foram interpretados sob a ótica da etnoecologia abrangente, ecologia humana e regimes de direito de propriedade. Os resultados sugerem que (i) o conhecimento local existente na região associado à atividade de extrativismo de castanha e áreas de coleta é extenso e alimentado por feedbacks ambientais cotidianos, devendo ser considerado para o co-manejo adaptativo; (ii) a organização e dinâmica dos territórios de coleta são complexos e divergem da situação fundiária oficial; (iii) as práticas de manejo que contribuem para conservação de B. excelsa são mais propícias de se manter em arranjos de regimes de propriedade mistos entre Estado e comunidade nos quais há menos conflitos e incertezas em relação ao acesso e uso das áreas de extrativismo.

Estratégias para implementação de governança ambiental no Refúgio de Vida Silvestre Mata do Junco, uma Unidade de Conservação Estadual de SergipeSilva, Carlos Miranda da 29 February 2016 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / The conservation of biodiversity is closely linked to the maintenance of the natural resources
and the strategies for protection of these natural assets. Among the Brazilian biodiversity
protection mechanisms there are the Conservation Units (UCs), established by Law 9.985/
2000, which regulates the National System of Protected Areas of Nature (SNUC). However,
only the implementation of these are as does not guarantee its maintenance, it is necessary the
effective and representative participation of the social actors that are embedded within its
management, i.e. the managing council, given the purposes that subsidized the creation of
such protected areas. The Wildlife Refuge Mata do Junco (RVSMJ) is a Conservation Unit
administered by the Ministry of Environment and Water Resources of Sergipe (SEMARH /
SE), in the municipality of Capela, state of Sergipe, with the objective of protect the
headwaters, vegetation, and shelter animal species, including the Callicebus coimbrai (titi
monkey) an endangered species. In addition to this UC has as its major management tools the
management plan and the consultative council. In this context, this study aimed to evaluate
the monitoring of the strategic actions identified by the Socio-Environmental Indicator
System for Conservation Units (SISUC), through its consultative council, to contribute for the
adaptive management of the RVSMJ. And also understand the level of social representation
that the council has on the UC and on their management by verifying what are the consensus
and conflict components, aided by the Social Representation Theory.
The use of this tool SISUC UC pointed out two indicators that are in alarming situation and
two underun satisfactory situation, which unfolded in six actions proposed by the Council
members so that these indicators could be monitored and improved. Of the six proposed
actions, four have being carried out and two did not succeed. However, the implementation of
this tool can be considered valid since it was successful in the majority of actions as well as
the use of this tool provided the empowerment and autonomy of the social actors. Thus, it can
be considered that the evidence presented by the directors in relation to their social
representations about the RVSMJ, the advisory board and the management of this
Conservation Unit encourage their participation and thus contributes to the improvement in
the process of management and consequently foster governance processes that permeate this
course, and in turn contributes to the maintenance and conservation of biodiversity. / A conservação da biodiversidade está diretamente ligada à manutenção dos recursos naturais
e às estratégias de proteção desses bens naturais. Dentre os mecanismos brasileiros de
proteção da biodiversidade encontram-se as Unidades de Conservação (UCs), instituídas pela
Lei 9.985/2000 que dispõe sobre o Sistema Nacional de Unidades de Conservação da
Natureza (SNUC). Entretanto, somente a implementação dessas áreas não garante sua
manutenção, faz-se necessário a participação efetiva e representativa dos atores sociais que
estão inseridos em sua gestão, isto é, o seu conselho gestor (deliberativo ou consultivo), tendo
em vista os propósitos que subsidiaram a criação de tais áreas protegidas. O Refúgio de Vida
Silvestre Mata do Junco (RVSMJ) é uma Unidade de Conservação administrada pela
Secretaria de Estado do Meio Ambiente e dos Recursos Hídricos de Sergipe (SEMARH/SE),
localizada no município de Capela, estado de Sergipe, com os objetivos de proteger as
nascentes, a vegetação, e para abrigar espécies da fauna, entre elas o Callicebus coimbrai
(macaco-guigó) espécie ameaçada de extinção. Além disso, a referida UC possui como
principais instrumentos de gestão o plano de manejo e o conselho consultivo. Nesse contexto,
o presente estudo teve como objetivo avaliar o monitoramento estratégico das ações
apontadas pelo Sistema de Indicadores Socioambientais para Unidades de Conservação
(SISUC) através de seu conselho consultivo, visando contribuir para gestão adaptativa do
RVSMJ, e ainda compreender as representações sociais que o conselho possui sobre esta UC
e sobre sua gestão verificando quais são seus elementos de consenso e conflitos, auxiliados
pela Teoria das Representações Sociais. Com o uso da ferramenta do SISUC nesta UC
apontaram-se dois indicadores que se encontraram em situação Alarmante e dois em situação
Insatisfatória, dos quais se desdobraram em seis ações propostas pelos conselheiros a fim de
que estes indicadores pudessem ser monitorados e melhorados. Das seis ações propostas,
quatro foram realizadas e duas não obtiveram sucesso. Contudo, a aplicação desta ferramenta
pode ser considerada válida, uma vez que houve sucesso na maioria das ações, assim como o
uso desta ferramenta proporcionou o empoderamento e a autonomia desses atores sociais. Por
sua vez, em relação à representação que os conselheiros possuem sobre RVSMJ e sobre sua
gestão foi possível constatar que para o RVSMJ essa representação está voltada à sua
preservação enquanto que para a gestão obteve-se como representação a responsabilidade e a
organização dos conselheiros para com a UC em questão. Desta forma, pode-se considerar
que os elementos apresentados pelos conselheiros em relação às suas representações sociais
sobre o RVSMJ, o conselho consultivo e a gestão desta Unidade de Conservação fomentam a
sua participação e consequentemente contribui para a melhoria no processo de sua gestão e
consequentemente fomentam os processos de governança que permeiam esta UC, e por sua
vez contribui para a manutenção e conservação da biodiversidade.

Les lâchers morphogènes : définition, expérimentations et protocole opérationnel de mise en oeuvre / From flushing flows to (eco)morphogenic flow releases : evolving terminology, practice, and integration into regulated river managementLoire, Rémi 06 September 2019 (has links)
Au fil des siècles, de nombreux cours d’eau ont été régulés par des barrages pour assurer différents besoins tels que la gestion des inondations, la production d’énergie hydro-électrique, l’irrigation, l’approvisionnement en eau potable, etc. Aujourd’hui, dans le tiers nord de la planète, 77% des cours d’eau sont concernés par la présence de ces ouvrages et de très nombreux ouvrages sont en cours de construction ou prévus dans les prochaines décennies. Les impacts des barrages, notamment ceux dont les réservoirs sont les plus volumineux, sont aujourd’hui bien connus. Leur influence, plus ou moins prononcée, peut notamment affecter les crues (débits, fréquence, pointe et durée), ce qui entraine de facto une modification de l’occurrence du « débit morphogène » naturel dans les tronçons situés en aval. Il en résulte une morphologie et une dynamique fluviales modifiées, avec des Incidences sur la biologie et les usages. Afin d’améliorer, voire de restaurer le bon fonctionnement des milieux aquatiques et rivulaires, il est de plus en plus souvent demandé aux gestionnaires de barrages de générer des débits élevés, dits « morphogènes », depuis leurs ouvrages. Ce travail de thèse s’est attaché dans un premier temps à clarifier les concepts de débits, lâchers et écoulements « morphogènes ». Il a été proposé une nouvelle terminologie s’intégrant dans le contexte plus large des débits environnementaux et des débits écologiques (environmental et ecological flows). Dans un second temps, les précédents travaux et les expérimentations menées sur la Durance, la Selves et l’Isère, ont fourni des éléments pour construire une méthodologie de mise en œuvre de lâchers morphogènes dans le cadre d’une gestion adaptative. Cette méthodologie opérationnelle repose sur une série d’étapes successives découlant d’un diagnostic préalable. Elle permet de déterminer les paramètres nécessaires au dimensionnement, d’identifier les contraintes et de définir les résultats attendus (compartiments visés, ordres de grandeurs des processus, etc.) pour évaluer l’efficience de l’opération. Enfin, grâce à la mise en œuvre d’indicateurs de déclenchement, elle fournit des éléments d’évaluation pour décider de renouveler, d’améliorer ou non le lâcher. / Over the centuries, many rivers have been regulated by dams to meet various needs such as flood management, hydropower production, irrigation, drinking water supply, etc. Today, in the northern third of the planet, 77% of watercourses are affected by dams and a very large number are under construction or planned in the coming decades. The impacts of dams, particularly those with the largest reservoirs, are now well-known. Their influence, more or less pronounced, can affect floods (flow, frequency, peak and duration), which results in a change of the occurrence of the natural "channel morphing discharge" in the downstream reaches. The result is a modified river morphology and dynamics, with impacts on biological communities and uses. In order to improve/restore aquatic and riparian environments, dam managers are increasingly being asked to generate high flows, known as "flushing flows” or “ecomorphogenic flows”, from their dams.This thesis focuses initially on clarifying the concepts of discharge, water release, and "ecomorphogenic flows”. A new terminology has been proposed that fits into the broader context of “environmental flows” and “ecological flows”. In a second step, previous works and experiments carried out on the Durance River, the Selves River and the Isère River provided elements to build a methodology for implementing ecomorphogenic flow releases as part of adaptive management. This operational methodology is based on a series of successive steps resulting from a preliminary diagnosis. It makes it possible to determine the parameters necessary for designing releases, identifying constraints and defining expected results (target compartments, orders of magnitude of process, etc.) to evaluate the efficiency of the operation. Finally, through the implementation of trigger indicators, it provides evaluation information to decide whether to renew, or improve releases or to replace them with other management actions.

Adaptiv styrning under osäkerhet : En kvantitativ studie om sambandet mellan osäker miljö och adaptiva styrprinciperLundin, Axel, Panelius, Althea, Pappiland, Diana January 2022 (has links)
Adaptiva styrprinciper har framhållits som potentiell lösning till en rad strategiskt kostsamma nackdelar kopplade till den traditionella årsbudgeten. Denna studie syftar till att studerasambandet mellan dessa adaptiva styrprinciper och osäker miljö. Teoribildningen som ligger till grund för det analytiska ramverket har tematiserats i fyra kategorier av adaptiva styrprinciper som visats återkommande i den tidigare forskningen rörande beyond budgeting och dess besläktade hybrider: decentralisering, adaptiv planering och resursallokering, adaptiv målsättning och prestationsmätning samt adaptiva incitamentspraktiker. Denna tidigare forskning har emellertid inte undersökt mindre företags benägenhet att implementera dessa praktiker, och hur detta förhåller sig under perioder av generell osäkerhet. Covid-19-pandemin utgör en unik möjlighet på så sätt att andra typer av osäkerhet tidigare har tagit formen av specifika attribut (exempelvis konkurrensutsättning), medan pandemin får anses vara generellt utan motstycke under de i övrigt rådande omständigheterna. Forskningsfrågan definieras därmed som: Har mindre svenska tillverkningsföretag anammat adaptiva styrprinciper i större utsträckning under pandemin? För att undersöka huruvida dessa styrprinciper har ett samband med osäker miljö på det sätt som antyds utifrån teori användes en kvantitativ metod. En enkät skickades till 616 svenska tillverkningsföretag med 10-199 anställda, varav 88 användbara svar samlades in. Även om respondenterna uppvisade bred tendens till anammande (såsom teorin skulle förutse) var inte denna förändringsgrad under pandemin statistiskt signifikant utifrån linjär sannolikhetsmodell. / Adaptive management practices have been touted as being the solution to a number of strategically costly problems connected to the traditional yearly budget. The purpose of this study is to examine the relation between adaptive management practices and an uncertain environment. The underlying theory of the analytical framework specifically concerns four adaptive management practices that have proven to be recurring in the beyond budgeting literature and its adjacent hybrids: decentralization, adaptive planning and resource allocation, adaptive goal and performance measurements and adaptive incentives. Prior research has overlooked the aspect of smaller companies and their willingness to change and adapt their management practices during times of general uncertainty. The Covid-19 pandemic during 2020-2021 constituted a rare opportunity in the sense that other types of uncertainty have tended to be specific (e.g. increased competition), whereas the pandemic is taken to be generally unprecedented in relation to all other aspects of the current business environment. The research question was therefore formulated as: Have Swedish small scale manufacturing companies adopted adaptive management practices to a larger extent during the pandemic? To examine whether the adoption of these tools relate to uncertain environments, in the manner in which the theory suggests, a quantitative approach was utilized. A survey was sent to 616 Swedish manufacturing companies with 10-199 employees, out of which 88 useful answers were gathered. Although the respondents showed tendencies of adoption across the board (as the theory would predict) the changes made during the pandemic did not reach statistical significance in the linear probability model.

Comparative case study analysis of adaptive groundwater governance and management regimes: Exploring ecosystem services in South Africa, Spain and GermanyKnüppe, Kathrin 22 October 2012 (has links)
Our daily lives depend on the provision of services by different ecosystems in which an important contribution is made by groundwater. To balance competing demands placed on groundwater for socioeconomic and ecological benefits constitute major challenges for water managers. At the policy-science interface the ecosystem service concept represents an appropriate approach to communicate management challenges in which researchers and politicians must take into account human and biophysical characteristics as intertwined systems. This study investigated the complexity of groundwater governance, and linkages between management and corresponding effects on ecosystem services. Empirical insights were derived from case studies in South Africa, Spain and Germany. The analytical focus includes (a) the degree of vertical (multi-level) and horizontal (cross-sectoral) integration which frame crucial characteristics of an adaptive governance regime and (b) the role of formal and informal institutions governing groundwater. In doing so, an conceptual and analytical approach was applied, especially developed to support a systematic and consistent investigation of policy and management processes. Evidence highlights that higher degrees of integration: (i) opens up the political arena for environmental perspectives, (ii) increases the quality of management plans, (iii) accelerates the implementation of measurements, (iv) mitigates conflicts between different groundwater users, and (v) increases the awareness of various ecosystem services. Further the results indicate that having well-crafted institutions in place does not automatically indicate successful groundwater management in the sense of bringing about positive results for socioeconomic or ecological sustainability. This work made a significant contribution to interdisciplinary research in the field of groundwater governance and ecosystem service management that builds the foundations for improving the policy-science interface.

Vertical gardening in a northern city; speculations for WinnipegUrben-Imbeault, Tamara 26 May 2015 (has links)
This practicum is a reference for vertical gardeners in cold climates. Winnipeg, Manitoba is explored, however findings may be applied to other cities in similar climates. First, the history of vertical gardening is discussed, then the types of vertical gardens currently on the market are described. These can be classified into two categories: soil bearing or non-soil bearing. Most designs are modular pre-planted systems that can be attached to any wall, as long as it satisfies the structural requirements recommended by the manufacturer. The benefits of vertical gardening have been shown to be rather extensive, covering a wide range of areas. Aesthetic improvement, reduction of the Urban Heat Island (UHI) effect, improvement of air quality, stormwater absorption, noise reduction, native habitat integration, reduction of heating and cooling costs for buildings, food production, marketing, and biophilia are all benefits explored in detail. Difficulties associated with vertical gardening are discussed, specifically the lack of knowledge and awareness of vertical gardens, lack of empirical evidence (or missing details in existing research), overall cost and lack of financial incentives, lack of industry codes, and various associated risks. Design framework exists within microclimate conditions unique to vertical gardens, as well as neighbourhood and regional (micro)climates. Theories relating to the study of green walls covered include the human ecosystem model, urban reconciliation ecology, habitat templating, the urban cliff hypothesis, and wall ecology. Suitable habitat templates identified for vertical gardens in Winnipeg are cliffs, sand dunes, alvars, mixed grass prairie and prairie potholes. Design parameters to be followed for vertical garden design in Winnipeg are to ensure that lightweight materials are used, to provide insulation to protect plants from sudden temperature changes, to choose plants that grow in the region and are adapted to grow in areas with limited soil, increased wind, varying degrees of sunlight (depending on orientation), and increased pollution and salt spray depending on location. / October 2015

Environmental performance indicators for the lower Mekong subregion developmentAmawatana, Chonchinee January 2008 (has links)
The application of environmental performance indicators (EPIs) has received increasing attention by both governments and international organisations as a tool for assessing complex environmental scenarios in national and local decision making processes. However, at the regional scale there is a gap in the application of EPIs, as this has not been well understood and defined due to a limited theoretical foundation and often insufficient data from all participant countries. The regional scale is important because it can incorporate natural ecosystems which often transcend national boundaries. A case study is developed for the Lower Mekong Subregion (LMS), where four riparian Southeast Asian countries (Lao PDR, Thailand, Cambodia, and Viet Nam) share the Lower Mekong River. The research proposes a conceptual framework to identify approaches for developing criteria for acceptable and appropriate EPIs which can be used to support and implement decision making processes by relevant organisations at the regional level. This research evaluates the application of environmental performance indicators using methodologies that assess cross-national quantitative and qualitative data and existing decision support systems. In addition, global and national indicators are examined for application and relation to the regional context. The research finds that the application of EPIs varies according to spatial scale, and is diverse among the four countries. Data availability is also identified as a major problem encountered during the development and selection of EPIs. The study finds that the governance of the existing regional body is ineffective due to differing agendas pursued by each participating country. This is because the current regional body is structured only to facilitate information exchange and cooperation in a limited manner, focusing so far only on water management issues. LMS regional goals need to be set in order to guide the stakeholders in identifying an appropriate set of EPIs. Most importantly, the research is intended to be a catalyst for encouraging the participants to integrate methods and other species of EPIs proposed in this research in their environmental assessment policies.

Coral reefs ecosystem services under global environmental change : interdisciplinary approaches to guide science and action / Services écosystémiques associés aux récifs coralliens dans un contexte de changements environnementaux globaux : approches interdisciplinaires pour guider la science et l’actionComte, Adrien 11 January 2018 (has links)
Les changements environnementaux globaux (CEG) menacent les écosystèmes marins et les populations humaines qui en dépendent. Une recherche scientifique croissante tente d’évaluer les impacts des changements environnementaux sur les écosystèmes et les services écosystémiques, notamment pour guider les politiques publiques. Focalisée sur les systèmes socio-écologiques (SSE) des récifs coralliens, cette thèse analyse les approches proposées dans la littérature et conçoit de nouvelles méthodologies, évaluations et indicateurs pour guider la science et l’action publique. Nous montrons qu’une stratégie de recherche régionale doit prendre en compte la complexité et produire de meilleures projections des impacts des CEG sur les récifs coralliens et les services associés. Nous cartographions des indicateurs à l’échelle globale pour évaluer où la dépendance des sociétés aux récifs coralliens sera affectée par les menaces globales dues à un niveau de CO2 élevé. Nous analysons comment la science répond aux impacts des CEG sur les récifs coralliens et nous identifions des pistes pour la recherche. Enfin, nous opérationnalisons une facette de la vulnérabilité, la capacité d’adaptation écologique, pour servir d’outil pour évaluer l’effectivité des actions locales dans un contexte de CEG. Ce manuscrit contribue à des avancées théoriques et méthodologiques sur l’évaluation des impacts, de la vulnérabilité et de l’adaptation aux CEG. Il développe des approches interdisciplinaires pour l’étude des SSE et des services écosystémiques, ciblant les récifs coralliens comme étude de cas. Enfin, il analyse l’émergence d’un champ scientifique sur les solutions aux GEC pour les récifs coralliens. / Global environmental change (GEC) in the ocean threatens marine ecosystems and the people who depend on them. A growing scientific effort is attempting to evaluate the impacts of environmental changes on ecosystems and ecosystem services and guide policy-making to respond to this global issue. Focusing on social-ecological systems of coral reefs, this thesis critically reviews the approaches put forward in the literature to understand gaps and to design new methodologies, assessments, and indicators to guide science and policy. Our findings show that a regionally targeted strategy of research should address complexity and provide more realistic projections about the impacts of GEC on coral reefs ecosystems and ecosystem services. We map global-scale indicators to understand where human dependence on coral reef ecosystems will be affected by globally-driven threats expected in a high-CO2 world. We then analyze how science is responding to the challenge posed by GEC on coral reefs and to identify gaps in research.Finally, we attempt to operationalize an overlooked component of vulnerability assessments, ecological adaptive capacity, to serve as a tool to help assess where local actions can be effective in the context of climate change. This manuscript contributes to theoretical and methodological advances to evaluate impacts, vulnerability and adaptation to GEC. It develops interdisciplinary approaches for the study of social-ecological systems and ecosystem services, targeting coral reefs as a case study. Finally, it synthesizes critically the emergence of a scientific field on solutions to GEC for coral reef social-ecological systems.
