Environmental and resource conflicts and conflict resolution practices in coastal areas of the North American Great Lakes: towards an integrated approach for policymaking

Skarlato, Olga 16 August 2013 (has links)
Environmental conflicts are multi-dimensional. Individual components of environmental and resource-related conflicts are closely interlinked with other structural societal elements, including economic, social, political and cultural developments. Coastal areas are significant for people’s subsistence, as well as industrial development, cultural heritage, and waterways; therefore, they require integrated research approaches and the implementation of comprehensive strategies of resource management, dispute resolution and conflict prevention. This qualitative exploratory study contributes to the development of the field of environmental conflict resolution (ECR) by examining the perceptions and experiences of 52 key stakeholders from the coastal areas of the Great Lakes region of Canada and the United States (US) with regards to environmental and resource conflicts and conflict resolution approaches. The study invited coastal stakeholders such as environmental policymakers, researchers, academics, educators and NGO members to share their perceptions, images, experiences and knowledge about environmental and resource conflicts and conflict resolution practices in the coastal areas of the Great Lakes. The framework of this holistic study integrates public policy, alternative dispute resolution, conflict analysis, project evaluation, dialogue and public participation, education and other creative interventions into an inclusive strategy of integrated environmental and resource management of coastal areas. Analysis of the study participants’ responses revealed several key findings. First, the multi-dimensional character of environmental and resource conflicts and the wide range of coastal stakeholders involved necessitate creating spaces for dialogue and communication among coastal stakeholders, which may facilitate relationship building and encourage collaborative problem solving and constructive conflict resolution. Second, establishing links between science and policymaking within environmental and resource management, as well as introducing conflict resolution education for coastal stakeholders, may significantly enhance the capacity of coastal stakeholders in ECR. Third, coastal stakeholders in the Great Lakes have an extensive and wide-ranging existing local knowledge, experience and expertise in resolving environmental and resource conflicts. Fourth, a conflict resolution system’s design developed in this study may serve as an integrated framework for the analysis and resolution of environmental and resource conflicts. This ECR system design involves such important components as conducting conflict and stakeholder analysis; identifying the root causes of conflict; bringing conflict participants together to discuss resolution options; and building in continuous evaluation of environmental conflict resolution processes.

Examining Local Jurisdictions' Capacity and Commitment For Hazard Mitigation Policies and Strategies along the Texas Coast

Husein, Rahmawati 2012 May 1900 (has links)
There have been studies on the role of land use planning and development regulations on hazard mitigation and the importance of including these in effective mitigation planning initiatives. However, little empirical research has examined how the local capacity and commitment affect the adoption and implementation of land use and development regulations to mitigate any type of hazards in the coastal areas. This study investigates hazard mitigation policies and practices at municipal and county level in the Texas coastal area and examines the influence of capacity and commitment for the adoption and implementation of these hazard mitigation strategies and actions. The data utilized in this survey were collected as part of a web-based survey. Responses were solicited from 267 local jurisdictions that consist of 226 cities and 41 counties. The survey was targeted to leading planner, or mayor/city manager and county judges. In total 124 responses were obtained, yielding an overall response rate of 46%. Study results show that local jurisdictions are employing a very limited a set of land use and development regulations that the literature has identified as important for hazard mitigation. There are considerable differences between municipalities and counties in the implementation of those policies. Municipalities tend to put more effort in employing building standards and development regulations, whereas counties more extensively employ information dissemination and private-public sector initiatives. In addition, statistical models are developed to assess the influence of local capacity and commitment on the adoption and implementation of hazard mitigation policies and strategies. Other factors such as jurisdiction type and location, hazard experience and exposure as well as population characteristics, are also examined in multivariate models. Results suggest that capacity and commitment of local jurisdictions have significant effects on the adoption and implementation hazard mitigation policies and strategies. Additionally, factor such as floodplain area, jurisdiction type municipality, and hazard experience have strong associated with implementation of hazard mitigation policies and strategies.

Assessment on Social Vulnerabilities to Climate Change – a Study on South-Western Coastal Region of Bangladesh

Laila, Fariya January 2013 (has links)
According to the Global Climate Risk Index, Bangladesh with its densely populated coastal areas is considered as one of the most vulnerable countries affected by climate change in the world. In this context, the goal of this research is to assess the social vulnerability of the south-western coastal communities of the country,which is becoming more vulnerable, trying to understand the underlying social conditions of coastal people who are dependent on limited natural resources. To do so, vulnerability indicators of exposure, sensitivity and adaptive capacity are analyzed using quantitative data collected from different sample areas and focus group discussions (FGD) were held with the local women in two study areas. The results show that a community in the area have close dependency on natural resources such as water, mangrove forest and also has a limited set of livelihood options. Also many households, above the traditional fishing and agriculture, have no secondary occupation or alternative livelihood options. Therefore, unpredictable seasonal patterns on the sea and land would threat livelihood and mainly their food security. Considering that the coastal areas have potential opportunities for nation’s sustainable development, assessing on social vulnerability to climate change will help to create regulation and awareness programs in order to minimize vulnerabilities.

Fusion de données provenant de différents capteurs satellitaires pour le suivi de la qualité de l'eau en zones côtières. Application au littoral de la région PACA / Fusion of images from different satellite sensors for monitoring water quality in coastal areas

Sylla, Diogone 16 December 2014 (has links)
Le suivi des zones côtières nécessite à la fois une bonne résolution spatiale, une bonne résolution spectraleassociée à un bon rapport signal sur bruit et enfin une bonne résolution temporelle pour visualiser deschangements rapides de couleur de l’eau.Les capteurs disponibles actuellement, et même ceux prévus prochainement, n’apportent pas à la fois unebonne résolution spatiale, spectrale ET temporelle. Dans cette étude, nous nous intéressons à la fusion de 2futurs capteurs qui s’inscrivent tous deux dans le programme Copernicus de l’agence spatiale européenne:MSI sur Sentinel-2 et OLCI sur Sentinel-3.Comme les capteurs MSI et OLCI ne fournissent pas encore d’images, il a fallu les simuler. Pour cela nousavons eu recours aux images hyperspectrales du capteur HICO. Nous avons alors proposé 3 méthodes : uneadaptation de la méthode ARSIS à la fusion d’images multispectrales (ARSIS), une méthode de fusion baséesur la factorisation de tenseurs non-négatifs (Tenseur) et une méthode de fusion basée sur l’inversion dematrices (Inversion)Ces 3 méthodes ont tout d’abord été évaluées à l’aide de paramètres statistiques entre les images obtenuespar fusion et l’image « parfaite » ainsi que sur les résultats d’estimation de paramètres biophysiques obtenuspar minimisation du modèle de transfert radiatif dans l’eau. / Monitoring coastal areas requires both a good spatial resolution, good spectral resolution associated with agood signal to noise ratio and finally a good temporal resolution to visualize rapid changes in water color.Available now, and even those planed soon, sensors do not provide both a good spatial, spectral ANDtemporal resolution. In this study, we are interested in the image fusion of two future sensors which are bothpart of the Copernicus program of the European Space Agency: MSI on Sentinel-2 and OLCI on Sentinel-3.Such as MSI and OLCI do not provide image yet, it was necessary to simulate them. We then used thehyperspectral imager HICO and we then proposed three methods: an adaptation of the method ARSIS fusionof multispectral images (ARSIS), a fusion method based on the non-negative factorization tensors (Tensor)and a fusion method based on the inversion de matrices (Inversion).These three methods were first evaluated using statistical parameters between images obtained by fusionand the "perfect" image as well as the estimation results of biophysical parameters obtained by minimizingthe radiative transfer model in water.

Kvicksilversituationen i Stockholms skärgård / The mercury situation in the Stockholm archipelago

Elving, Hannes January 2010 (has links)
<p>Kvicksilverutsläppen har på senare år minskat i omfattning men utsläpp sker fortfarande och det finns ett stort lager i naturen.

Kvicksilver biomagnifieras uppåt i trofinivåerna, från att vara lägst halter i plankton och bottenfauna till att vara högst halter i rovfiskar.

Integrated Management Policies For Coastal Archaeological Environments Of Turkey: Erdemli-silifke Coastal Region, Mersin

Nayci, Nida 01 September 2010 (has links) (PDF)
Being important natural areas due to togetherness of terrestrial and water ecosystems / coastal araes (sea, lake and river coasts) possesses important historic and cultural environments shiowing relationship of mankind with water developed during different periods since ancient periods onwards. In this sense / having housed various civilizations since anquity onwards, Turkey has diverse and rich coastal archaeological sites. However, in addition to natural processes occuring in short and long terms due to their dynamic and evolving nature, athmospheric events, coastal erosions, climate change / developments of rapid urbanization, tourism, industry and infrastructure which have enourmously accelarated since Industrial Evolution have causes irreversibel destruction of natural, cultural and archaeological values of coastal araes. The coastal management policies that have been gaining importance during recent years aim to develop appropriate policies for providing sustainability of natural and cultural values of coastal areas within their conservation-use balance. Within the light of this information / the scope of this thesis is to identify integrated management policies for coastal archaeological environments and to discuss and bring together existing planning and management tools in Turkey in order to develop national management policies. For this purpose, in the First Chapter of the study, historical development of international policies, theoretical discussions and related concepts in relation with planning and and management of coastal archaeological areas is presented. Accordingly, principles related to concept of Integrated Coastal Zone Management (ICZM) are put forth. This section is concluded with related to reasons and contents for necessities of integrated management of coastal archaeological environments. In the second Chapter of the study, the planning and management tools related with integrated management of coastal archaeological sites within the legislative and administrative system of Turkey are discussed. For this purpose / firstly, historical development archaeological heritage conservation and coastal policies are studied. Secondly / present tools related to decision-making process including survey and registration, planning, implementation, control and monitoring are displayed through the examination of the current situation. The Third Chapter includes case-study research which has been structured in two phases. In the first phase / Regional Analysis, by which impacts of national policies within the light of historic perspective and existing tools of Turkey on Mediterranean Region is put forward. Second phase of case-study includes detailed research related to values and problems of archaeological sites located in Erdemli-Silifke coastal region. The Fourth Chapter, includes evaluations related to results of case-study research. In this sense / the cultural landscape characteristics of coastal areas are put forward within the light of assessments regarding integrity of archaeological, natural and rural characteristics of Erdemli-Silifke coastal region. In the second phase / the natural and man-caused problems threatening these values, which are followed by administrative problems according to existing legislative and administrative system that have been displayed in the Second Chapter, are discussed. Within the light of these information and experiences, integrated management principles required for integrated conservation of coastal archaeological sites are proposed throughout the Proposals and Conclusions Chapter, which constitutes the last section of the study. In the second phase, an administrative model for case-study area is proposed. The last section of the study which forms the Conclusions phase includes evaluations to achieve development of national level policies in Turkey.
