チベット高原の1990〜2020年の食料生産を分析し、気候変動シナリオ下での将来予測を行った。食料生産は32.33%増加し、自給自足を達成。気候温暖化と農業技術向上により、耕作地10%削減でも生産維持可能だが、極端気象の頻発がリスクとなる。
English
This study analyzes food production on the Tibetan Plateau from 1990-2020 and models future trends under climate scenarios. Production increased 32.33%, achieving self-sufficiency. Warming and improved agriculture could maintain yields even with 10% cropland reduction, but increasing extreme weather poses risks to food security and nutrition.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、山岳地域や傾斜地農業の持続可能性が課題となっている。本論文の傾斜地農地の休耕と生態系サービス向上の分析は、日本の中山間地域政策に示唆を与える可能性がある。ただし、チベット高原特有の環境条件が強いため、直接適用には注意が必要。
In the global GX context
This paper provides empirical evidence on balancing food production and conservation in high-altitude regions under climate change. Globally, it contributes to the literature on land-use trade-offs and adaptation strategies, relevant for similar mountainous regions like the Andes or Himalayas. The findings on retiring steeply sloping cropland could inform sustainability policies in other regions.
👥 読者別の含意
🔬研究者:Provides a longitudinal analysis of food production and conservation trade-offs on the Tibetan Plateau, useful for researchers studying land-use change and climate adaptation in high-altitude ecosystems.
🏢実務担当者:Offers insights for agricultural planners and conservation managers on the potential to reduce cropland while maintaining yields through improved practices and climate trends.
🏛政策担当者:Highlights the need to account for extreme weather risks in food security planning, and the opportunity to align conservation goals with agricultural modernization.
📄 Abstract（原文）
The Tibetan Plateau, the Earth’s highest and largest plateau, has a harsh environment for agriculture, and is a global biodiversity hotspot, raising the challenge of simultaneously satisfying food production and conservation goals. Currently, agriculture involves crop production on steep slopes and overgrazing, which threatens future productivity. The Tibetan Plateau is also undergoing climate change. We evaluate food production from 1990 to 2020 and use these results to model future trends and risks to food production on the Tibetan Plateau. We assess the feasibility of achieving both food production and conservation goals simultaneously under climate change scenarios. Food production increased 32.33% over three decades, providing 2,892.98 kcal d −1 cap −1 , more than enough to satisfy food self-sufficiency. Under climate change, the Tibetan Plateau will become warmer and wetter under Shared Socioeconomic Pathways (SSPs) SSP126, SSP245, and SSP585, which combined with agricultural advances (e.g., improved mechanization and irrigation), will likely result in increased yields even with a 10% reduction in cropland area—greater than the total area of all steeply sloping cropland, thereby allowing retirement of steeply sloping cropland and livestock reductions while still meeting food production goals. Meanwhile, key ecosystem services, including carbon sequestration, water retention, and habitat quality, are also projected to improve substantially. Nonetheless, the increasing frequency and severity of extreme weather events are expected to reduce food production, undermine current dietary requirements and may threaten the minimum nutritional intake required for humans.
