In 2021, 30 Loggerhead Turtles have been taken into critical care at Bunbury’s Dolphin Discovery Centre. Last year, there were only four. Changes in water temperature in the Leeuwin Current from El Nino conditions has seen a higher rate of turtles found washed up along south western coastlines. The lower temperatures of southern waters causes the endangered turtles’ metabolism to shut down, threatening survival. Once rehabilitated the turtles are released off the coast of Exmouth.

Centre for Marine Ecosystems Research, Edith Cowan University @CMER_ECU

Chanelle Webster, a PhD student from Edith Cowan University (ECU), is studying how climate change influences the resilience of estuarine seagrass meadows. Seagrasses thrive in our estuaries filtering nutrients and sediments, supporting fisheries and are a food source for the iconic Black Swan. During the 2017 summer, an extreme rainfall event flushed the Derbal Yaragan estuary or Swan-Canning with fresh water. This caused a mass die-off of the seagrass. Chanelle found populations exposed to naturally more variable salinities recovered while those from a stable salinity environment did not recover within the study time frame. Her findings identified population specific resilience which can be used to future-proof our seagrass meadows to further climate change pressures.

The latest climate change projections delivered by the IPCC in its 6th assessment report present a sobering picture for Australia’s coastal and marine regions. Rising sea level is projected to contribute to coastal recession in many locations. These changes in combination with increased ocean and air temperatures and decreased rainfall will alter ecosystems with far reaching impacts for coastal areas.

A year 4 class from Margaret River Independent School visited Redgate Beach as part of Nature Conservation Margaret River's Adopt a Spot Program. The students learnt about the impacts of coastal erosion and the importance of native vegetation and helped to restore the coastline. At least 300 cuttings of native pigface were planted, and invasive onion weed was removed. Local coastal carers helped to co-ordinate the planting and ensured the hard-working students had assistance with the 'deep dune' style of planting.

Lal’s Lookout at the mouth of the Greenough River is heavily utilised and valued by the community, though like many similar places is being loved to death. Heavy foot and vehicle traffic into the dune, which is directly exposed to the prevailing winds resulted in significant vegetation loss and sand movement. The City of Greater Geraldton has recently implemented soft coastal management methods at Lal’s lookout, such as sand trap hessian fencing and brushing, with the support of Coastwest funding.

1 Recurrent coral bleaching in north-western Australia and associated declines in coral cover

Until recently coastal reefs of northwestern Australia have been relatively unaffected by higher sea-surface temperature and coral bleaching compared to eastern Australian reefs. However, these researchers identified relative declines in coral cover ranging from 38 to 92%, and since 2013 it has declined to historically low levels which is consistent with global trends. Given rising temperatures, there is a high likelihood that WA reefs will experience more frequent marine heatwaves, coral bleaching and mortality events in the future, and therefore action is needed now to support the resilience of coral reef ecosystems.

2 Future-proofing conservation priorities for sea level rise in coastal urban ecosystems

The authors developed and applied a multi-ecosystem approach to assist in planning for the conservation and protection of coastal ecosystems as rising sea level changes the spatial configuration of coastal habitats. Using urbanised Moreton Bay in Queensland as a case-study, they found that planning based on present conditions will not adequately capture conservation priorities for the future, and has associated financial consequences. Multiple scenarios and sensitivity tests identified critical/priority areas to be protected.

3 Estimating blue carbon sequestration under coastal management scenarios

Erosion of soils in 'blue carbon' ecosystems – mangrove forests, tidal marshes, and seagrass meadows – is a large carbon emissions threat, so managed retreat could sequester much more than a no-action alternative. This study of 2500 km of coastline in southeastern Australia used models to quantify which management actions produce the greatest gains in sequestration, and found that the large potential value loss from coastal erosion is signfiicantly greater than potential gains from conserving or restoring ecosystems.

4 A visualization tool for citizen-science marine debris big data

To reduce the deleterious effects of anthropogenic marine debris (largely plastic) on sensitive and vulnerable marine and estuarine ecosystems, the authors developed a web-based visualization tool for an Australian marine debris database. The five elements of the source-to-sea (S2S) framework enable harm minimization by working with relevant actors (engagement) to identify cause and effect (characterize and diagnose) before developing remedial action with continuous monitoring and evaluation (design, act and adapt).

5 Good enough for governance? Audit and marine biodiversity offsetting in Australia

Biodiversity offsetting is often presented as a way to manage competing demands of environmental protection and economic development. However, showing that there is/will be no net loss (NNL) of biodiversity is extremely difficult, due to the highly uncertain nature of marine systems, the low knowledge of ecological restoration, and complex administrative governance. The authors found that there is a lack of transparency in ecological outcomes because marine offsets do not rely on accurate quantification of biodiversity losses and gains.

6 Coastal flood risk within a peri-urban area: Sussex Inlet district, SE Australia

Given the increased risk of coastal flooding, especially due to rising sea level and an expanding periurban population, the authors sought to develop a a consistent approach to mapping risk. They used high-resolution remotely sensed data to map exposure, vulnerability and biophysical variables, and then integrated the flood risk triangle with future scenarios of demographic and climate change to develop flood-risk maps that can be applied across spatial scales to improve planning strategies.

7 Sustainable Oceans and Coasts National Strategy 2021-2030

Oceans and coasts support our communities and our economy, but they are under immediate and increasing threat from multiple overlapping pressures, including climate change, pollution, invasive species, habitat and biodiversity loss, and a growing population with greater infrastructure needs. This strategy recognises that our natural environment, will play a central role in forcing sustainability transitions, and that the time frame for achieving this change is urgent – we must address the blue economy and resilient coastal communities in order to achieve sustainable oceans and coasts for Australia.

8 Determining the Shoreline Retreat Rate of Australia Using Discrete and Hybrid Bayesian Networks

Evaluating shoreline retreat rate (SRR) on different spatial-temporal scales is critical for effective coastal management. Large-scale evaluations typically rely on data-driven methods such as Discrete Bayesian networks (BNs). Here, the authors propose a new method, the Hybrid BN to incorporate continuous variables without discretization. Findings indicated BNs can reflect the impact of different factors on coastal evolution, and predict future shoreline change by exploring historical data.

1 In search of social sustainability in marine spatial planning: A review of scientific literature published 2005–2020

The authors examined how social sustainability was addressed in 310 peer reviewed scientific articles on marine/maritime spatial planning (MSP) and show that very few papers published between 2005 and 2020 developed a coherent framework for engaging with social sustainability. Since the papers mostly addressed particular social concerns (e.g., participation and engagement, equity and social justice, socio-cultural values and preferences), there is a need for both the academic and practice-based communities to address how the multidimensions of social sustainability interact with each other, as well as with economic and environmental aspects of marine planning and governance.

2 Marine Spatial Planning cross-border cooperation in the ‘European Macaronesia Ocean’: A participatory approach

Marine Spatial Planning (MSP) generally includes ecological, physical processes and administrative jurisdictions of multiple countries, which creates a complex challenge for the transboundary cooperation. To achieve coherent MSP processes in shared marine socio-ecological systems, a pilot programme with early stakeholders’ involvement was created, to reach consensus and develop cross-border mechanisms, in archipelagic remote regions with no visible maritime borders (Azores, Madeira and Canary Islands).
