エチオピアの保護地域ネットワークを分析。30x30目標達成には3倍の拡大が必要だが、既存の保護地域は森林減少抑制に効果がある一方、社会的コスト（世帯の食料不足）も発生。国内関係者は拡大より既存ネットワークの効果向上を優先。環境・社会間のトレードオフがグローバル目標達成の核心であることを示唆。
English
This study analyzes Ethiopia's protected area network, finding that meeting the 30x30 target would require a threefold expansion into high-opportunity-cost areas. Existing protected areas reduce forest loss and agricultural expansion but impose social costs equivalent to 3.9 million fewer household-months of adequate food. National stakeholders prioritize improving existing network effectiveness over expansion, highlighting trade-offs central to global biodiversity commitments.

📄 Abstract（原文）
Achieving global biodiversity targets, such as the commitment to conserve 30% of the planet by 2030, depends on the ability of individual countries to translate targets into reality. While there has long been recognition that protected areas can bring costs as well as benefits, the implications of this for delivery of global targets have not been fully explored. We focus on Ethiopia, a country supporting globally important biodiversity but facing substantial poverty challenges. We characterize the extent and representativeness of Ethiopia's protected area network, demonstrating that a threefold expansion-particularly into ecoregions with higher opportunity cost-would be required to meet the Kunming-Montreal Global Biodiversity Framework Target 3. Using a quasi-experimental approach (accounting for known confounders and exploring sensitivity to potential unobserved confounders), we show that the existing protected area network has reduced forest loss and agricultural expansion, and helped to maintain grasslands. Yet, this has brought social wellbeing costs equivalent to 3.9 million fewer household-months of adequate food. Surveys show that national conservation stakeholders recognize these challenges and prioritize improving effectiveness of the existing network over expansion. Our findings highlight that trade-offs between environmental and social outcomes are not simply challenges to be managed, but are central to whether global biodiversity commitments can be delivered.
