カリフォルニア大学サンディエゴ校のスクリップス海洋研究所の研究者を中心とする国際チームは、新たな海洋保護戦略として「海洋繁栄地域（Marine Prosperity Areas, MPpAs）」の包括的な枠組みを提案しました。このアプローチは、人間の福祉と海洋・沿岸環境の回復を同時に促進することを目指しています。具体的には、エコツーリズムの推進や持続可能な水産養殖の支援など、地域社会の経済成長と生態系の保全を両立させるための戦略的な投資とパートナーシップを強調しています。この枠組みは、2030年までに世界の海洋の30%を保護するという国際目標「30 by 30」の達成にも寄与すると期待されています。

Mechanisms for marine ecological protection and recovery, including area-based conservation tools like ‘Marine Protected Areas’ (MPAs) are necessary tools to reach the Aichi Target or the forthcoming 30×30 target set by the Kunming-Montreal Biodiversity Framework. However, full ecosystem recovery takes years to manifest and the idea that MPA protection alone will foster human well-being is frequently contradicted by socio-economic evidence. Therefore, a new framework for marine area-based conservation and ecosystem restoration that reconciles the discrepancies between ecological recovery and socio-economic growth timelines is needed to effectively meet global biodiversity conservation targets. We introduce the concept of ‘Marine Prosperity Areas,’ (MPpA) an area-based conservation tool that prioritizes human prosperity as opposed to passively relying on ecosystem recovery to catalyze social change and economic growth. This concept leverages a suite of tried-and-true community-based intervention and investment strategies to strengthen and expand access to environmental science, social goods and services, and the financial perks of the blue economy. This data-driven framework may be of interest to stakeholders who support traditional area-based conservation models, but also to those who have been historically opposed to MPAs or have been excluded from past conservation processes.
