Coastal lagoon systems in Tasmania form a fundamental part of coastal ecosystems. Healthy lagoons support local biodiversity, and play a key role in nutrient cycling and flood protection. They provide opportunities for sustainable aquaculture, fishing and tourism, while also being appreciated for their recreational amenity and cultural values. Sustainable management of coastal lagoons is essential to environmental and socioeconomic development.

There is limited information about the ecosystem drivers that are influencing the changes being observed in Pipe Clay Lagoon, leading to knowledge gaps in decision making tools and monitoring strategies required to identify and mitigate these changes. The proposed application is a multifaceted approach to investigate the environmental drivers of change in Pipe Clay Lagoon. The findings can then be used to provide valuable guidance for the management and conservation of other coastal lagoons in Tasmania facing similar challenges, providing a model for proactive monitoring and ongoing sustainability.

The FRDC has a responsibility to ensure that research is undertaken to assist in the management of fisheries and aquaculture resources for ongoing sustainability. The changes being experienced in Pipe Clay Lagoon will have implications on the availability and suitability of the lagoon as a sustainable aquaculture site. The planned approach and objectives of the application align with the FRDC’s R&D Plan for 2020-2025 through:

- Building people's capacity and capability
- Ensuring that resulting knowledge and innovation is adopted for impact through awareness of the needs of the ‘adopter’, local context and effective networking
- Continual improvement and collaboration of industry and community to deliver competitive advantage, healthier ecosystems and community support
- Provision of foundational information

Equally and importantly the application aligns with the NRM Strategy for Southern Tasmania 2030 for Pipe Clay Lagoon and similar systems in that wetland health is improved for socio-economically important systems by working with key partners and encouraging investment in monitoring, land and water management practices and on-ground works.
The enthusiasm of those engaged in the stakeholder consultation process was a strong indication of the need, interest and urgency of the application.

There is a need to increase effective engagement between fishing and aquaculture stakeholders and climate science and scientists in an ongoing strategic way, and not ‘just’ for single-project outcomes.

Improved engagement will help increase understanding of the likely implications of a changing climate in relevant contexts, and lay foundations for a shared exploration of available options for reducing risk exposure. We have worked with stakeholders and the FRDC Extension Officer Network to design a strategy that will engage fishing and aquaculture stakeholders on existing knowledge regarding risks and opportunities associated with a changing climate, to enable resource managers and researchers to better understand the ways in which many sectors are already adapting autonomously and to identify the barriers to further adaptation, and to co-design solutions that are relevant at local- and industry-levels to help build climate-ready communities and to stimulate economic resilience.

In many cases (but not all), extensive information regarding marine climate change - including key risks to fisheries and aquaculture producers (at a high level) - is already available, along with information on how to develop adaptation plans. However, despite this, progress and uptake within most sectors in terms of planned adaptation responses has been very slow – although many individual operators are already making ‘autonomous’ changes to their day-to-day operations in response to climate change drivers. If these changes are being made without access to best available knowledge, then it is very likely that substantial portions of these responses are maladaptive in the longer term, or may be countervailing to planned government adaptations (see Pecl et al 2019, Ambio, https://link.springer.com/article/10.1007/s13280-019-01186-x). This is a pattern evident within many different industries around Australia and across the rest of the world. ‘What’ needs to happen has thus been outlined in general terms in many cases, but such information is not co-developed or provided in consultation with end-users in ways that resonate or are useful to them. This project will address this need for relevance and usefulness.

The project aims to develop reflexive, ongoing, and two-way knowledge exchange between industry representatives, operators and manager, and the marine climate change impacts and adaptation research sector, so that solutions are co-designed, usable, and adoptable.
