Multi-scale multi-level marine spatial planning: A novel methodological approach applied in South Africa.

ABSTRACT: This study proposes and discusses a multi-scale spatial planning method implemented simultaneously at local and national level to prioritize ecosystem management actions across landscapes and seascapes. Mismatches in scale between the occurrence of biodiversity patterns and ecological processes, and the size and nature of the human footprint, and the different levels and scope of governance, are a significant challenge in conservation planning. These scale mismatches are further confounded by data resolution disparities across and amongst the different scales. To address this challenge, we developed a multi-resolution scale-linked marine spatial planning method. We tested this approach in the development of a Conservation Plan for a significant portion of South Africa's exclusive economic zone, adjacent to the east coast province of KwaZulu-Natal (the SeaPlan project). The study's dataset integrated the geographic distribution of 390 biodiversity elements (species, habitats, and oceanographic processes) and 38 human activities. A multi-resolution system of planning unit layers (PUL), with individual PUs ranging in resolution from 0.2 to 10 km, was designed to arrange and analyse these data. Spatial priorities for conservation were selected incrementally at different scales, contributing conservation targets from the fine-, medium- and large-scale analyses, and from the coast to the offshore. Compared to a basic single-resolution scale-unlinked plan, our multi-resolution scale-linked method selects 6% less conservation area to achieve the same targets. Compared to a multi-resolution scale-unlinked plan, our method requires only an additional 5% area. Overall, this method reflects the multi-scale nature of marine social-ecological systems more realistically, is relatively simple and replicable, and serves to better connect fine-scale and large-scale spatial management policies. We discuss the impacts of this study on protected area expansion planning processes in South Africa. This study showcases a methodological advance that has the potential to impact marine spatial planning practices and policies.

Project description:The importance of examining multiple hierarchical levels when modeling resource use for wildlife has been acknowledged for decades. Multi-level resource selection functions have recently been promoted as a method to synthesize resource use across nested organizational levels into a single predictive surface. Analyzing multiple scales of selection within each hierarchical level further strengthens multi-level resource selection functions. We extend this multi-level, multi-scale framework to modeling resistance for wildlife by combining multi-scale resistance surfaces from two data types, genetic and movement. Resistance estimation has typically been conducted with one of these data types, or compared between the two. However, we contend it is not an either/or issue and that resistance may be better-modeled using a combination of resistance surfaces that represent processes at different hierarchical levels. Resistance surfaces estimated from genetic data characterize temporally broad-scale dispersal and successful breeding over generations, whereas resistance surfaces estimated from movement data represent fine-scale travel and contextualized movement decisions. We used telemetry and genetic data from a long-term study on pumas (Puma concolor) in a highly developed landscape in southern California to develop a multi-level, multi-scale resource selection function and a multi-level, multi-scale resistance surface. We used these multi-level, multi-scale surfaces to identify resource use patches and resistant kernel corridors. Across levels, we found puma avoided urban, agricultural areas, and roads and preferred riparian areas and more rugged terrain. For other landscape features, selection differed among levels, as did the scales of selection for each feature. With these results, we developed a conservation plan for one of the most isolated puma populations in the U.S. Our approach captured a wide spectrum of ecological relationships for a population, resulted in effective conservation planning, and can be readily applied to other wildlife species.

Project description:The globally accelerating environmental crisis calls for radical changes in the governance of ocean resources towards a more sustainable and socially equitable world. Transdisciplinary sustainability research and networked knowledge-to-action approaches are critical parts of this change. The effective application of such approaches still puzzles social actors (individuals and networks) willing to act in more transformative ways. We conducted twelve participatory network mapping activities to assess the perception of high-level federal government institutional entrepreneurs on the structure and dynamics of an emerging socio-political arena for marine spatial planning (MSP) in Brazil. Our informants, mostly cognizant of their own intra-governmental structures, anticipate the MSP arena to remain self-enclosed, with changes only occurring within the federal government structures in the coming years. Their perceptions were largely conservative, narrow, and unambitious and therefore unfit to generate regime transformations. The limited awareness of response capacities beyond the federal government potentially leads to the endurement of the low performance already present in the MSP arena. Results from the participatory network mapping informed a five-step functional ocean governability analysis pointing to key potential contributions to support a critical turn in MSP: 1. envision situated interactional narratives to leverage regime shifts; 2. build a shared understanding of and anticipating transformative coevolutionary dynamics; 3. build awareness of the potential synergies among disparate but innovative area-based responses; 4. specify inter-network-based limitations and the necessary changes underpinning potential leaps in performance levels of ocean governance orders; 5. make power asymmetries explicit to stir structurally tailored strategic action by less influential groups. We discuss the potential role of inter-network strategies and actions and how they may confront the symptoms of depoliticized MSP pathways and the risks of it becoming an instrument of further marginalisation and power asymmetry in Brazil.Supplementary informationThe online version contains supplementary material available at 10.1007/s40152-021-00250-1.
