Bottom trawling is a common fishing method for harvesting demersal marine resources such as prawns and ground fish species. However, bottom trawling is known to have negative impacts on marine ecosystems and several measures have been suggested to sustainably manage the fishing method including, mapping trawling pressure and restricting its use away from fragile marine ecosystems. In this study, we map spatio-temporal distribution of trawling effort using 8900 trawls obtained from logbook statistical data and consequently evaluate the effectiveness of a Vessel Monitoring System (VMS) and a Prawn Fisheries Management Plan (PFMP) in the Malindi-Ungwana Bay, Kenya. The PFMP and VMS aimed at restricting prawn trawling to areas beyond 3 nm from shoreline since 2010 in order to reduce conflict with artisanal fishers. Results show spatio-temporal adjustments in the distribution of fishing effort and catch rates of prawns following regulatory changes in the bay. Encroachment in no-trawl areas occurred gradually between 2011 and 2017 with some years (2013, 2016) depicting over 50% of fishing effort in the no-trawl areas. Trawling within the restricted zone produced higher catch per unit effort (CPUE) of prawns compared to fishing outside the zone. Introduction of VMS in 2017 led to a significant reduction of fishing effort in no-trawl area of about 80% by 2018. The change in fleet behaviour in the bay after introduction of the VMS, provides important insights on how marine spatial planning and technology could be applied to enhance compliance with fishing area regulations, reduce resource use conflicts and promote sustainable fisheries.
Marine/Maritime Spatial Planning (MSP)
Appropriate spatial planning and environmental management of coastal areas in cities are essential to maintain a balance of environmental quality and urban development, whereas unscientific planning practices lead to the degradation of coastal ecosystems. Coastal Regulation Zone (CRZ) guidelines are currently being used in India for management of the coast. These guidelines are difficult to implement and do not take into account the variation of physical characteristics of the coast. The alternative to this approach is a quantitative land classification in coastal areas based on geospatial and multiple criteria decision making techniques. In this work, we applied these two approaches to the three case locations of the coastal lands in Mumbai region representing areas which are i) predominantly urban, ii) rural and iii) no development areas. The classification results of the two approaches are systematically compared and contrasted to show the lacunae in the present method of CRZ classification and to highlight the advantages of using the quantitative approach in coastal land classification. The comparative analysis shows that the quantitative approach takes into account the variation of physical features along the coast and will help in conserving the coastal ecosystem more efficiently.
In this paper, we explore the Polish fishers' perception of marine spatial planning (MSP) processes off the Polish coast. Our research is guided by the radical approach to MSP which, at its centre, places the interplay between MSP actors and their stakes. Our approach certainly considers the relationship of MSP with politics and power, questioning the rational choice. Hence, we have selected fishers as a group which is often recognised as less privileged, with no or little influence on MSP. Firstly, using semi-structured interviews, we investigated the ways in which fishers identify the challenges inhibiting their meaningful participation in MSP. The fishers pointed out data and knowledge gaps as well as a perceived limited agency in decision-making. However, misconceptions about MSP, i.e., equating MSP to off-shore wind farms, appeared to be the most significant short-term challenge. Secondly, through a focus group with MSP planners, we explored what the planners recognised as barriers to the fishers' active participation, and gauged the planners' awareness regarding the problems identified by the fishers. Both groups, fishers and planners, identified similar challenges. The major difference between these two groups was the issue of who should be responsible for addressing the concerns they identified. We conclude that much of the fishers’ reluctance towards MSP stemmed from their negative experiences in previous marine management initiatives, leading to a general lack of trust among the members of this group. We speculate that this lack of trust could have been diminished through a properly implemented stakeholder mapping in the pre-planning phase. However, the schedule stipulated by the EU MSP Directive, i.e., to prepare the plans before early 2021, did not allow the necessary time for the accomplishment of this step. We, thus, postulate that the stakeholder consultation process should be decoupled from formal MSP, and it should be most active in the pre-planning phase.
Effective marine spatial planning (MSP) requires evidence-based decision-making processes in order to achieve sustainable use of marine resources and ecosystem services. In accordance with this purpose, decision support tools (DSTs) were used as the primary assistant of planners and managers. As a further step of existing review efforts on DSTs, this research aimed to add value to current knowledge by capturing end user opinions on their applications in MSP processes. For this purpose, perceptions and experiences on tools were acquired using an inclusive questionnaire. In total, 92 MSP experts were reached from 28 countries to collect information on: (i) DST users’ profile; (ii) the contribution of tools in MSP implementation processes, (iii) user opinions and experiences; and (iv) their expectations to draw recommendations and to give insights for future developments. Results revealed that developers should keep tool-user interaction from development to application stage and focus on a publicly accepted MSP working flow. Besides, new efforts on environmental data collection are needed to enable ecosystem-based approach in MSP. Hereby, this research analysed end user perceptions and opinions on DSTs, and it concludes that users require tools providing multi-functionality, integrity and ease of use.
Marine spatial planning (MSP) has been put forward as a way to more comprehensively manage marine environments by balancing human demands and protecting areas that support ecosystem function. Given the recent motivations for countries to adopt large-scale marine spatial planning approaches, ensuring these plans are grounded in social-ecological resilience theories is essential for long-term success. Drawing upon recent academic attention from a range of disciplinary areas, this review explores current practices and applied examples of published case studies from around the world that have integrated social and ecological spatial information using GIS techniques. This review intended to use these case studies to guide directions of future MSP research that considers social-ecological resilience theories. Five overall themes were uncovered. First, extractive uses, such as fisheries, were often given priority in MSP processes, which even though important, may undermine the social resilience of coastal communities by not supporting the diversity of non-extractive economies. Second, the quality of ecological spatial data used in the studies varied greatly, often with little consideration of how ongoing human demands may influence long-term ecological resilience. Thrid, many GIS techniques were used to integrate social and ecological data including: descriptive maps, site prioritisation techniques, and predictive modelling. Lastly, only a small number of studies considered cross-ecosystem influences and only two incorporated potential climate change impacts on social institutions and marine ecosystems. Overall, there is a need for progressing GIS predictive modelling techniques to assess and link the responses of social and ecological systems to MSP solutions in order to support long-term social-ecological resilience.
Marine spatial planning (MSP) seeks to integrate traditionally disconnected oceans activities, management arrangements, and practices through a rational and comprehensive governance system. This article explores the emerging critical literature on MSP, focusing on key elements of MSP engaged by scholars: (1) planning discourse and narrative; (2) ocean economies and equity; (3) online ocean data and new digital ontologies; and (4) new and broad networks of ocean actors. The implications of these elements are then illustrated through a discussion of MSP in the United States. Critical scholars are beginning to go beyond applied or operational critiques of MSP projects to engage the underlying assumptions, practices, and relationships involved in planning. Interrogating MSP with interdisciplinary ideas drawn from critical social science disciplines, such as emerging applications of relational theory at sea, can provide insights into how MSP and other megaprojects both close and open new opportunities for social and environmental well-being.
This research reveals attitudes towards enclosure and privatisation of ocean space. The development of spatially distributed industries like marine renewables and aquaculture, the need for marine conservation, and the ongoing emphasis on spatial aspects of marine planning, have resulted in increasing encroachment into the marine environment. The study, situated in Scotland, investigates the attitudes of stakeholders who are affecting, or being affected by, these processes. The attitude analysis, done by Q methodology, highlights potentially conflicting priorities and processes. Five unique factors emerged. These are expressed as: free seas, the ‘greater good’, mitigating losses, local powers, and the status quo. The topography of views revealed demonstrates clear tensions between key players in Scotland's marine planning landscape, and calls into question the processes for effective collaborative working for sustainable and conflict-free development at sea. The paper concludes with an appeal for changes in rights to be accounted for in decision making processes, accompanied by better dissemination of information regarding rights at sea, governance and the future of the blue economy.
Although stakeholder participation is transversal to other steps of the Marine Spatial Planning (MSP) process, its recognition and adoption is context dependent. Considering that MSP plans need to be periodically evaluated, not only in relation to their outputs and outcomes, but also through an analysis of the processes used to achieve the results, criteria to evaluate participation throughout the whole process are needed. However, a robust and comprehensive assessment framework focused specifically on participation is not available up to date. Therefore, this study proposed an assessment for such operational analysis in order to support assessment of consequences related to the participatory strategy chosen (e.g., increased social acceptance). A Stakeholder Participation Assessment Framework (SPAF) was developed and divided in two phases: Phase I based on key theoretical aspects ‘why, who, when and how to engage stakeholders’, as well as on criteria for costs (these five criteria were divided in 15 sub-criteria, and instructions based on social science knowledge to analyse each one were given); and Phase II in which a list of questions about participatory consequences can be addressed based on specific criteria of the first phase and stakeholders' feedback. SPAF can be used not only to evaluate MSP planning cycles but also to plan meaningful participatory processes; therefore, contributing to strengthen MSP processes and to promote more horizontal and integrated ocean governance approaches.
Marine coastal environments are often socially complex public areas that need equitable spatial planning approaches. Understanding the extent of extractive and non-extractive uses and the social dynamics that may be driving patterns of use is essential if the spatial plan is to support the social resilience of a marine area. In this study, a combination of fuzzy-set multi-criteria GIS modelling and negative tie social network analysis were used to explore social uses and conflicts based on sketch-mapping interviews with five key stakeholder groups (ecotourism, Aboriginal Traditional Owners, commercial and recreational fishing, and water sports) within a Marine Protected Area (MPA). Most of the areas within the MPA were regularly used by the stakeholders, with non-extractive and extractive stakeholders occupying similar spatial extents, with each stakeholder group having a different pattern of use. However, stakeholder groups had different levels of perceived priority to access these areas and support of the current spatial management plan, especially within the ecotourism and Aboriginal Traditional Owner groups. The investigation of social conflicts in shaping patterns of use revealed that most stakeholder conflicts do not necessarily occur in areas of overlaps, but generally in areas of high biodiversity and easy access through marine infrastructure. Ecotourism groups had the most perceived conflicts over marine space, which shaped their use towards certain no-take zones that protected high biodiversity and would also provide protection from other conflicting stakeholder uses (e.g., boating, fishing). Overall, the method outlined in this paper presents a way for marine spatial management to consider not only the extent and diversity of social uses in a marine environment but also the spatial-social dynamics that may determine the success of the spatial plan in supporting long-term social resilience.
After a spout of optimism surrounding Myanmar's so-called democratic transition in the post-2010 period, civil-society organisations and academics are beginning to highlight rampant and violent resource grabs unfolding across the country. Delving into the Northern Tanintharyi landscape in the Southeast, this article aims to understand interrelated dynamics of coastal and agrarian transformation during the state-mediated capitalist transition of the past 30 years. Conceptually developing a landscape-approach that sees individual ‘grabs’ in a relational manner and as part of broader political-economic struggles, the article shows how the Myanmar military regime sought a conjoined ocean and land control-grab in pursuit of rent extraction from productive foreign capital in fisheries and off-shore gas sectors. Empirically, these dynamics are traced from the scale of regional geopolitical struggles down to two particular villages in Northern Tanintharyi – highlighting resulting processes of differentiation along lines of class and gender. This conceptual framework and explanation of drivers behind ocean and land control-grabbing, in turn, complicates prevalent policy solutions in Myanmar (and elsewhere) that reduce the question of resolving resource-grabs to the pursuit of an elusive ‘good governance’.
