Ocean governance in South Africa: Policy and implementation

Naidoo, Ashley Desmond January 2020 (has links)
Philosophiae Doctor - PhD / Ocean Governance in South Africa has gained momentum over the last decade with the publication of the Green and White Papers on the National Environmental Management of the Ocean in 2012 and 2014, and the promulgation of the Marine Spatial Planning Act in 2019. Parallel to this South Africa developed and implemented the Operation Phakisa Ocean Economy Development Programme and declared a network of twenty Marine Protected Areas. The timing of this study over the last five years allowed the opportunity to undertake a detailed study of the Ocean Governance Policy Development and Implementation as the formulation of the policy and its early implementation unfolded. The Study is primarily based on interpretation of the Green and White Papers as the primary and directed ocean governance policies produced by the Government of South African and the National Department of Environmental Affairs. It places these most recent specific ocean environmental policies in the context of the many other environmental policies that exits in the country.

Ciência integrada para gestão costeira: potencialidades e desafios / Integrated science for coastal management: potentialities and challenges

Grilli, Natalia de Miranda 22 August 2017 (has links)
A complexidade dos problemas socioambientais atuais enfrentados pela humanidade tem demandado abordagens mais participativas de produção científica, como a Ciência Pós-Normal, e de gestão, como a Gestão Baseada em Ecossistemas e a Gestão Costeira Integrada. Todas essas abordagens têm como um de seus princípios a Interdisciplinaridade, reconhecendo que o desenvolvimento de pesquisas científicas que busquem integrar diversas disciplinas, múltiplos sistemas de conhecimento e aproximar ciência e gestão são de fundamental importância em prover soluções às complexas questões postas pela sociedade. Apesar disso, a prática da interdisciplinaridade ainda encontra resistência no meio político-acadêmico onde se insere. Assim, o presente trabalho buscou abordar os desafios e as potencialidades de se desenvolver esse tipo de ciência, com foco em ecossistemas marinhos e costeiros, a partir de duas escalas de planejamento e execução científicas (top-down e bottom-up, respectivamente): i) da perspectiva de agências de fomento à pesquisa no Brasil; e ii) da análise de um projeto de pesquisa oceanográfico que objetivou ter uma abordagem interdisciplinar, como estudo de caso. A partir de entrevistas e análises documentais, buscou-se ainda fornecer subsídios ao desenvolvimento de futuros projetos científicos interdisciplinares e aprimoramento da interface ciência-gestão costeira. / The complexity of current socioenvironmental problems faced by humanity has pushed scientific endeavors towards more participative approaches, such as Post-Normal Science, and management, such as Ecosystem Based Management and Integrated Coastal Management. Interdisciplinarity is understood as one of the key elements of these approaches. Thus developing scientific researches that intend to integrate different disciplines, multiple knowledge systems and bring together policy and science is essential to provide answers to the complexities of societal issues. Nevertheless, the development of interdisciplinary research still faces many political and academic obstacles. Therefore, this study presents the challenges and potential of developing integrated science, focusing on coastal and marine ecosystems. We did that from two different planning and execution scales (top-down and bottom-up, respectively): i) from the perspective of research funding agencies; and ii) from the perspective of researchers of an oceanographic research project that intended to work in an interdisciplinarity manner as a study case. From interviews and document analyses, we provide contributions to the development of future interdisciplinary scientific research projects and to the improvement of science-policy interfaces in coastal zones.

A Framework for Identifying Appropriate Sub-Regions for Ecosystem-Based Management in Northern Gulf of Mexico Coastal and Marine Environments

Ziegler, Jennifer Sloan 14 December 2013 (has links)
Nearly half of the population of the United States lives in coastal regions, and millions of visitors from across the nation and world enjoy the coasts every year. Coastal and marine areas provide for recreation, economic activities essential for the financial health of the nation, and vital ecological services. As they provide so many benefits to the U.S., it is vital to protect and preserve the coastal and ocean areas from the increasing, competing demands they are facing. In order to protect and preserve these complex systems, a comprehensive approach incorporating science, engineering, humanities, and social sciences should be taken; this approach is commonly referred to as Ecosystem-Based Management. This dissertation focuses on developing a framework that can be used to identify appropriate sub-regions in Northern Gulf of Mexico coastal and marine environments for the purposes of Ecosystem-Based Management. Through this work, the roles of three management protocols used for managing coastal areas – coastal and marine spatial planning, ecosystem-based management, and integrated ecosystem assessment – were examined individually as well as their integrations with each other. Biological, ecological, physical, human, and economic indicators for partitioning an ecosystem were developed and weighted for each management protocol using the analytic hierarchy process and expert elicitation. Using the weighted indicators, a framework for identifying sub-regions and estuarine classification system was developed. The framework and classification system were applied to five estuaries within the Northern Gulf of Mexico: Barataria, Galveston, Mobile, and Perdido Bays and Mississippi Sound. Initial results from this work show that: 1. Sub-regions can be identified as associated to each other based upon indicator data values and not upon physical location. 2. Even though the weights calculated for the management protocols vary significantly, for systems that were not highly homogeneous in indicator data values, the different weights did not produce the vastly different cluster maps expected. 3. The scale work indicates that to identify appropriate sub-regions using the developed framework, a larger grid size produces more consistent results for larger systems whereas a smaller grid size produces more consistent results for smaller systems. Recommendations for further research are also presented.

Counting on their migration home: an examination of monitoring protocols and Saanich First Nations’ perspectives of Coho (Oncorhynchus kisutch), Chinook (O. tshawytscha) and Chum (O. keta) Pacific Salmon at Goldstream River and Saanich Inlet, Southern Vancouver Island, British Columbia

Paul, Roxanne 20 August 2007 (has links)
Records of abundance of salmon that return to their natal spawning stream (escapements) are important indices that can assist with monitoring, conservation, and management of a salmon population over time. On their own, however these data reveal very little about the habitat, ecosystem and human communities that salmon encounter on their journey from freshwater to sea and back again. This research examines monitoring protocols for Goldstream River salmon stocks (coho, chinook and chum Pacific salmon). It includes and reaches beyond biostatistics from stream surveys to gauge First Nations’ artisanal fishing activities at Goldstream River and Saanich Inlet as well as their commercial chum fishing endeavours in Saanich Inlet on south Vancouver Island, British Columbia. Methods included summations of major themes from interviews on traditional ecological knowledge (TEK) shared by local Saanich First Nation fishers whose families have lived in the communities around Goldstream River and Saanich Inlet for more than 200 years. Analyses of Goldstream salmon escapements for the period 1932 to 2004 and native harvest statistics of chum caught from Saanich Inlet between 1982 and 2004 are integrated with results from analysis of TEK research undertaken for this project. Key recommendations arising from the results of this research are: stream habitat restoration in response to loss and degradation of salmon-bearing streams; modification of stream survey procedures to measure for morphological and physiological attributes including indicators of the health of Goldstream salmon; monitoring and eliminating sources of pollution to Saanich Inlet waters; implementing precautionary measures to ensure that overfishing of Goldstream salmon and shrimp in Saanich Inlet does not recur; and safeguarding naturally abundant Goldstream chum populations at the river. Under current management of the Goldstream chum fishery, the maximum carrying capacity (K) or target escapement of chum that the Goldstream River spawning grounds sustain is 15,000. Based on population assessments as well as physiography and ecosystem dynamics, I infer that Goldstream River’s K for its natural chum population is between ~16,000 and 18,000; ~1,500 for the mixed stocks of natural and hatchery enhanced coho; and ~50 for chinook (based on the river’s naturally occurring populations between 1932 and 1973) or ~385 enhanced chinook (based on the returning population from 1975 to 2002 since hatchery enhancement took place). A co-management relationship exists between Fisheries and Oceans Canada (DFO) resource managers and the Saanich First Nations bands (Saanich Tribal Fisheries councilors). Improvements to communication, collaboration and information sharing between DFO resource managers, Goldstream hatchery operators and Saanich First Nations with regards to decisions made about Goldstream salmon stocks are, however, necessary. In this thesis, I propose a model with recommendations for compatible fisheries management goals and techniques including adaptive management and ecosystem-based management to address this problem.
