Designate and convert Marine Protected Areas into fully protected no-take / HPMA zones
Why this action matters
Evidence-groundedDesignating and converting Marine Protected Areas into fully protected no-take / HPMA zones is critical to addressing the degradation of marine ecosystems, as current levels of biodiversity loss and ecosystem disruption are unsustainable. Evidence shows that marine biodiversity loss is driven by overexploitation and habitat degradation, and stronger protection measures, such as no-take zones, have been demonstrated to support recovery and resilience in marine ecosystems, aligning with broader goals of planetary health and sustainable food systems.

Consequences of this action
Evidence-groundedThe action itself
Designating and converting Marine Protected Areas into fully protected no-take / HPMA zones excludes all extractive activities, including fishing, to allow marine ecosystems to recover and regenerate.
UK implications
In the UK, converting MPAs to HPMAs could support the recovery of marine biodiversity and fish stocks, which may contribute to long-term food security by enhancing the resilience of marine ecosystems, though current evidence does not quantify specific UK-level impacts on emissions or public health directly.
Global implications
UK leadership in designating HPMAs aligns with global efforts to protect 30% of the ocean by 2030 and supports international marine conservation goals, contributing to the recovery of global marine biodiversity and the mitigation of climate change through enhanced blue carbon storage.

Climate Resilience
The marine environment is under significant stress, with evidence showing that ocean acidification has already led to a decline in surface pH, which is projected to increase at the fastest rate in millions of years [Pörtner et al., 2022] This degradation of marine ecosystems threatens the resilience of food systems, as the global food system is responsible for introducing novel entities into the environment, which can harm marine and terrestrial biodiversity [Rockström et al., 2023] Designating and converting Marine Protected Areas into fully protected no-take zones can enhance climate resilience by restoring natural elements, which is crucial for reducing eutrophication and supporting ecosystem recovery [Rockström et al., 2023] The current rate of biodiversity loss is already exceeding the biosphere's capacity to recover, with species extinction rates expected to increase significantly if no action is taken [Pörtner et al., 2022] Marine Protected Areas can serve as critical refuges for species facing climate-induced habitat loss, as climate change has already driven hundreds of local species losses and mass mortality events in both terrestrial and marine ecosystems [Pörtner et al., 2022]
