Incorporating Climate Change Impacts Within Harvest Strategies: An Overview of Approaches
Biodiversity Conservation

Bessell-Browne, Pia. et al.

2025
Ensuring that harvest strategies are robust to climate change is a top priority for many fisheries jurisdictions globally. This is because climate change is altering ecosystem structure and the productivity of marine species. We outline a range of approaches for incorporating climate change impacts within harvest strategies, including how a harvest strategy is specified and changes to monitoring requirements. Approaches evaluated include the use of extended stock assessments, multi-species and ecosystem models, revised management reference points, implementing regime shifts in model parameters, the provision of climate-sensitive catch advice, projections under alternative climate change scenarios and expanded use of management strategy evaluation. We evaluate the utility of these approaches against cost, data needs and uncertainty criteria; highlight key learnings from a range of global jurisdictions and demonstrate the broad array of options available outside of direct incorporation of climate variables within stock assessments. We identify approaches that have been successfully implemented and show that the most complex responses are not always the most successful. While there is no one-size-fits-all way to incorporate climate change within harvest strategies, we outline the need for flexible management arrangements. We also provide examples of approaches that have been successfully implemented, demonstrating that many of the most data-intensive responses will only be applicable in a few cases, necessitating the application of cheaper, less data-intensive approaches that are associated with greater uncertainty.

Na Navua Catchment e wili ena vanua vakaturaga ko Serua kei na Beqa Lagoon e wili ena qoliqoli ni vanua ko Serua kei Rewa. Na Navua Catchment kei na Beqa Lagoon edua na vanua ka i vurevureu ni bula vakailavo, bula vakaveiwekani vakavanua, ka vutuniyau ena veimataqali veikabula. E dua na vanua ka vutuniau kina na veimataqali vurevure ni lavo kei na bula ni veisiga me vaka na teitei kei na susu manumanu ena vanua bucabuca ena yasa ni uciwai. E vakayagataki tale ga me nodra sala ni veitosoyaki na lewenivanua, na uciwai levu, kei kena vei uciwai lalai, vakabibi vei ira na koro era tu vakayawa. E toka mai na uluniwai e dua na barisavu, vakatokai na Upper Navua Gorge, e sa okati me vanua taqomaki nira bula tu kina na veimataqali kau kei na manumanu era sega ni kune ena dua tale na vanua, se era sa voleka ni kawaboko (endangered). Na veika bula e kune ena vanua qori e yaga tale ga me kakana se wainimate. E vakatalega kina na Beqa Lagoon sa wili me wasawasa e taqomaki, vakatokai na ‘Particularly Sensitive Sea Area (PSSA) ka ratou a mai vakadeitaka na isoqosoqo na International Maritime Organization. Era bula tu na Beqa Lagoon e levu sara na veimataqali veikabula, me vaka na lase, qio, ika kei na vonu. E vanua ka kaukauwa sara nai nodra sema vakavanua kei na nodra bula vakayalo na lewenivanua.
