Diagnóstico sócio-ambiental do Balneário Cassino e áreas adjacentes - Rio Grande-RS : subsídio ao gerenciamento costeiro integrado localSarilho, Karina Aparecida January 2003 (has links)
As preocupações com a integridade e o equilíbrio ambiental das regiões costeiras decorrem do fato de serem as mais ameaçadas do planeta, justamente por representarem para as sociedades humanas um elo de ligação e de intensa troca de mercadorias entre si, com a exploração desordenada e muitas vezes predatória de seus recursos naturais, tornado-se, já na era industrial o principal local de lazer, turismo ou moradia de grandes massas de populações urbanos. A vocação de uso de determinada paisagem esta relacionada às funções que a mesma desempenha. O que ocorre é que o padrão de desenvolvimento adotado e a atual configuração sócio-econômica determinam usos que nem sempre coincidem com a sua melhor utilização. A fim de subsidiar futuros planos de uso e ocupação racional do solo das áreas naturais adjacentes ao Balneário Cassino (Rio Grande, RS), de acordo com os preceitos do Gerenciamento Costeiro Integrado, desenvolveu-se um Dianóstico Sócio-Ambiental da área dentro de abordagem sistêmica. Foram considerados principais componentes e processos urbanos e ambientais, definidos a partir da interpretação de aerofotografias, levantamentos de campo quali-quantitativos e informações bibliográficas. Os resultados são apresentados na forma de tabelas, quadros, levantamentos fotográficos, modelos diagramáticos conceituais, e mapas temáticos, que permitiram entender a organização estrutural e funcional da paisagem, e fundamentar uma ordenação espacial dos usos desta área, de modo a adequá-los às suas especificidades ambientais, histórico-culturais, sócio-econômicas e legais. / The integrity and the environmental equilibrium of coastal zones are increasingly becoming a concern to environmental scientists. Coastal environments are one of the most threatened in the world. Besides, they represent, to the human societies, a link of connection and intense exchange of merchandise amongst each other, with disordered and, at many times, predatory exploration, becoming, already at the industrial age, a main site of leisure, tourism and habitation of large masses of urban population. The vocation of a determined landscape is related to the functions and roles it plays. What actually occurs is that the development pattern adopted and the actual socio-economics determine the uses, which not always coincide with its best utilization. In order to assist future plans of rational use and occupation of natural areas adjacent to Cassino's Bathing Resort (Rio Grande, RS), in agreement with the Integrated Coastal Zone Management, a social-environmental diagnosis of the study site was developed using the systemic approach. The main environmental and urban processes and components were considered. They were defined based on aerophotos interpretation, quail-quantitative field survey and bibliographic information. The results, presented in the form of tables, photographic surveys, conceptual diagrammatic models and thematic maps, allowed to understand the structural and functional organization of the landscape and to establish a spatial ordering of land use to adequate them to their environmental, historic-social, socioeconomics and legal specificities.

Public participation in the marina developments at Port Vincent and Wallaroo on the Yorke Peninsula, South AustraliaAlexander, Felicity Anne. January 2000 (has links) (PDF)
Bibliography: leaves 98-103. Examines the role of public participation in coastal protection and coastal management in two marina developments proposed for Yorke Peninsula. The study concluded that there was potential for the South Australian Planning System to incorporate sustainable development and involve the public to a greater extent. The Environmental Impact Assessment process has been perceived as a means of incorporating the principles of ecologically sustainable development at a community level, but the extent to which this has occured for the marina developments at Port Vincent and Wallaroo is limited.

Groundwater-Seawater Interactions : Seawater Intrusion, Submarine Groundwater Discharge and Temporal Variability and Randomness EffectsPrieto, Carmen January 2005 (has links)
Fresh groundwater quality and availability in coastal areas is affected by seawater intrusion into coastal aquifers, and coastal water quality and ecosystem status may be significantly affected by groundwater pollutants that are transported into coastal waters by submarine groundwater dis-charge (SGD). This thesis uses an overall regional perspective for investigating: i) seawater intru-sion and its possible control in sustainable coastal groundwater management; ii) SGD and its relevant quantification as one interacting part among the diverse main regional pathways of freshwater and tracer/pollutant inputs from land to sea; and iii) the integrated system functioning of both i) and ii) as main components of the same coastal groundwater system. Results show that intensive pumping rates may be maintained for a long time before major re-gional seawater intrusion problems are recognized by too high salinities in pumped groundwater. After such late recognition, pumping wells are no longer useful and a common strategy of mov-ing groundwater pumping further upstream from the coast only increases the extent of the salt-water intrusion zone into the aquifer. An alternative strategy may be to control seawater intrusion through artificial groundwater recharge, for instance by sufficiently treated wastewater, which may considerably reduce long-term trends of salinity increase in pumped groundwater, even for small artificial recharge rates compared to pumping rates. In general, account for natural spatial-temporal variability and randomness may be essential for relevant prediction of groundwater dynamics for management purposes. Spatial and temporal randomness effects, however, may not be additive, but rather largely overlapping, with either spatial or temporal randomness being the dominating part that must be accounted for in predictive groundwater dynamics calculations. Aquifer depth is identified as an important control parameter in this context, yielding much greater temporal randomness effects in shallow than in deep aquifers. Combined simulation results suggest a simple, approximately linear regional relationship between total SGD and its hydrologically determined freshwater component. Tidal oscillation may signifi-cantly affect such linear dependence of steady-state SGD, but primarily for low SGD conditions. High SGD appears to depend mainly on a dominant freshwater component, which effectively counteracts density-driven flow of seawater into the aquifer and thus decreases also effects of sea-level oscillation on the seawater component of total SGD. Comparative analysis between different SGD estimation methods in different reported high-SGD regions of the world indicates possible anomalously large regional SGD estimation from tracer concentrations in coastal waters, by confusing different main pathways of groundwater flow and pollutant inputs to the sea. / QC 20101012

A Systems Approach to Identify Indicators for Integrated Coastal Zone ManagementSanò, Marcello 09 June 2009 (has links)
El objetivo de la tesis es establecer un marco metodológico para la identificación de indicadores GIZC orientados a problemas y temas de interés, para contextos geográficos específicos. La tesis parte de la idea de que los sistemas de indicadores, utilizados para medir el estado de la costa y la implementación de proyectos de Gestión Integrada de las Zonas Costeras (GIZC), deben orientarse a problemas concretos de la zona de estudio y que su validez debe ser comprobada no sólo por la opinión de los expertos, sino también por la percepción de los usuarios y por el análisis estadístico cuantitativo. / The problem addressed by this thesis is the identification of site-specific and problem-oriented sets of indicators, to be used to determine baseline conditions and to monitor the effect of ICZM initiatives.The approach followed integrates contributions from coastal experts and stakeholders, systems theory, and the use of multivariate analysis techniques in order to provide a cost-effective set of indicators, oriented to site-specific problems, with a broad system perspective.A systems approach, based on systems thinking theory and practice, is developed and tested in this thesis to design models of coastal systems, through the identification of the system's components and relations, using the contribution of experts and stakeholders.Quantitative analysis of the system is then carried out, assessing the contribution of stakeholders and using multivariate statistics (principal components analysis), in order to understand the structure of the system, including relationships between variables.The simplification of the system (reduction of the number of variables) is one of the main outcomes, both in the participatory system's design and in the quantitative multivariate analysis, aiming at a cost-effective set of key variables to be used as indicators for coastal management.

Fri passage och tomtplatsavgränsning : En studie av två länsstyrelsers överprövningsärenden av kommunala strandskyddsdispenserPantzar, Linda January 2012 (has links)
Strandskyddet i Sverige är en del av allemansrätten som innebär att var och en har rätt att under ansvar färdas fritt i den svenska naturen, den rätten skyddas av strandskyddslagstiftning i miljöbalken. Dispens från förbuden i strandskyddslagstiftningen kan medges av kommunen. Strandskyddslagstiftningen har sedan 2009 fått nytt innehåll, bland annat att Länsstyrelsen är den myndighet som efter att kommunen medgett strandskyddsdispens granskar och i vissa fall överprövar dessa ärenden. En ny regel som ska säkerställa att fri passage ges vid tomtplatsbestämning infördes även 2009. Ett antal överprövningsärenden har studerats för att kunna analysera tillämpningen av bestämmelserna av tomtplats och fri passage. En litteraturstudie är tänkt att svara på om krav på fri passage förekommer i andra länder. Litteraturstudien ska ge kunskap om de svenska rättsförhållanden. Intervju och enkät kompletterar studien. Studien har gett svar om hur strandskyddslagen tillämpas avseende tomtplats och fri passage vid olika åtgärder i strandskyddsområde. Ett helhetsperspektiv ges även, där alla beslut om dispenser i materialet påverkas av regeln om fri passage och vilka åtgärder Länsstyrelsen gör med tomtplats. Helhetsperspektivet visar att en stor del av fallen inte anses beröras av frågan enligt Länsstyrelsens handläggare, men att trots det bevaras eller möjliggörs fri passage som ett resultat av deras beslut i 40% av ärendena. Med ett åtgärdsperspektiv presenteras bland annat varför olika typer av ersättningsbyggnader medges dispens utifrån tomtplatsbegreppet. De beslut som innebär att hel fastighet med strandkontakt bestäms till tomtplats är av naturliga orsaker det största hindret mot fri passage. I Stockholms Länsstyrelse förekommer det i 20% av studerat material. Av de fastigheter som avgränsats till hel tomtplats förekommer betydligt större tomtplatser än vad lagstiftningen rekommenderar. De oväntade resultat som kommit fram i studien gör gällande att halländska förhållanden kan visa på en flexibilitet i tillämpningen av strandskyddet vid mindre vattendrag, medan Stockholms förhållanden indikerar brister vid utredning huruvida ett område kan anses privat ianspråktaget eller ej. Nyckelord: Strandskyddslagstiftning, fri passage, tomtplats, komplementbyggnad, ersättningsbyggnad, lucktomt, strandskyddsdispens, överprövning. / Beach protection in Sweden is part of the public nature, which in this study means that everyone has the right to responsible travel freely in the Swedish nature. This right is secured by shoreline protection legislation in the environmental legislation. In certain circumstances it is possible to grant exemptions from the prohibitions in the shoreline protection. Shore protection legislation has changed and new content was added in 2009. Among other things, the County Administrative Board is now the authority that review, and in sometimes try the cases where the municipality has accepted a waiver. It can entitles as a "double check". A new rule that will ensure that free passage is provided when the use of properties concerning the area for plot get limited by a plot determination, was introduced in 2009. A number of cases up for double checking have been studied to analyze the application of the provisions of plot site and free passage. A literature review is intended to find out whether demands for free passage occurs in other countries. The literature review will also provide knowledge about the Swedish legal relations. Interviews and a survey complements the study. The study has provided answers on plot site and free access application from different perspectives. One perspective is how all decisions on exemptions in the material are affected by the rule of free passage and what steps the County Board takes with plot site. The following view shows that a large proportion of the cases are not considered to be affected by the issue of the County Administration Officer. Another perspective is to look at the actions permitted. This includes a presentation of why different types of replacement buildings are dispensed, regarding to plot site concept. Needless to say, decisions where an entire property with beach contact is determined to plot site is the biggest obstacle to free passage. In Stockholm County Administrative Board, this occurs in 20% of the studied materials. In the cases where the entire property was defined as plot site, there exists considerably larger plots than the law recommends. The unexpected results that have emerged in the study argues that Hallands´ conditions may show a flexibility in the application of shore protection close to small streams, while circumstances in Stockholm indicate shortcomings in investigating whether an area can be considered private utilization or not.

Vulnerability Of Coastal Areas To Sea Level Rise: A Case Study On Goksu DeltaOzyurt, Gulizar 01 February 2007 (has links) (PDF)
Climate change and anticipated impacts of sea level rise such as increased coastal erosion, inundation, flooding due to storm surges and salt water intrusion to freshwater resources will affect all the countries but mostly small island countries of oceans and low-lying lands along coastlines. Turkey having 8333 km of coastline including physically, ecologically and socio-economically important low-lying deltas should also prepare for the impacts of sea level rise as well as other impacts of climate change while participating in mitigation efforts. Thus, a coastal vulnerability assessment of Turkey to sea level rise is needed both as a part of coastal zone management policies for sustainable development and as a guideline for resource allocation for preparation of adaptation options for upcoming problems due to sea level rise.
In this study, a coastal vulnerability matrix and a corresponding coastal vulnerability index &ndash / CVI (SLR) of a region to sea level rise using indicators of impacts of sea level rise which use commonly available data are developed. The results of the matrix and the index enable decision makers to compare and rank different regions according to their vulnerabilities to sea level rise, to prioritize impacts of sea level rise on the region according to the vulnerability of the region to each impact and to determine the most vulnerable parameters for planning of adaptation measures to sea level rise.
The developed coastal vulnerability assessment model is used to determine the vulnerability of Gö / ksu Delta (Specially Protected Area), Mersin that has unique geological, ecological and socio-economical properties which are protected and recognized by both national and international communities.

Evaluation of the Commercial Groundfish Integration Pilot Program in British ColumbiaMawani, Tameezan 16 September 2010 (has links)
In 2006, the Minister of Fisheries and Oceans Canada (DFO) accepted an industry proposal called the Commercial Groundfish Integration Pilot Program (CGIPP), which integrated each of the seven commercial groundfish fisheries in British Columbia. The industry proposal, developed by the Commercial Industry Caucus (CIC), was the result of guiding principles developed by DFO that focused on the conservation of certain rockfish species on the Pacific Coast. If industry had not developed a plan, DFO would have developed an alternative fishing plan (AFP). This thesis evaluates whether DFO's conservation objectives were met under the CGIPP and if there were any social and economic impacts. These same impacts are compared to what may have occurred under the AFP. The results of this thesis indicate that the CGIPP is a sustainable template for multi-species commercial fisheries--a first step in achieving an ecosystem-based approach to fisheries management.

Knowledge sharing and distribution in an open system : a case study of the Eastern Cape Estuaries Management Programme.Mosia, Lucky Nomusa. January 2003 (has links)
Knowledge management is largely a social process. It is more about the community‘s understanding, skills and values in relation to their practices than technology. Knowledge is generated and shared through social interaction of people. Exploring the community‘s acts of communication and interaction can help to understand the knowledge they have as well as the knowledge gaps that are apparent. It can also aid in discovering ways in which their practices are shaped and constrained by the knowledge they have. The purpose of this study was to determine the optimal means of knowledge sharing and knowledge distribution in an open system using the Eastern Cape Tyolomnqa Estuary as a case study. Different scholars stated in their different works that sharing knowledge is problematic in most organizations, whether they are formal or informal organizations. There are several reasons that have been identified as to why people do not want to share their knowledge. To achieve the objectives of this study, both secondary and primary sources of data were used. This included literature from various sources, such as books, journal articles and information from the Internet that has been reviewed and analyzed. Interviews and focus groups were used to collect data. Interviews were conducted with 16 people who were purposively selected from the Buffalo City Council, Tyolomnqa Conservancy, Tyolomnqa Estates, Tyolomnqa Forum, and Phozi, Ncera, Sandile and Xhama communities. The key informants were people with management positions, and community leaders. The interviews were unstructured. After collecting data by means of face-to-face interviews focus groups, workshops were convened with the Tyolomnqa Forum, and Phozi, Ncera, Sandile and Xhama communities. The self-administered questionnaire was additionally used as a data collection technique for researchers. Data were analyzed through content analysis and the use of SPSS, and presented in the form of tables and figures. It was identified that their knowledge sharing was fragmented and there was no formal organisational structure to bring communities along the Tyolomnqa Estuary to work together as one would do in bureaucratic organizations like companies. The Tyolomnqa Estuary Forum, which has vested interests in estuary management, could be used as model to provide the organisational infrastructure to facilitate the acquisition and sharing of knowledge on the management of estuaries. It is envisaged that such forums can be a viable mechanism of facilitating the harnessing and sharing of knowledge on the sustainable use of estuaries at the local level. / Thesis (M.I.S.)-University of Natal, Pietermaritzburg, 2003.
