英国のSwansea Universityの研究チームは、「自然処方(Nature Prescribing)」の効果を高めるためには、緑地の量だけでなく、生態学的な質を評価することが重要であるとする新たな評価フレームワークを提案した。自然処方は、心身の健康改善を目的に公園や森林などでの活動を医療・福祉分野から勧める取り組みとして広がっているが、これまで多くの研究は緑地面積やアクセス性に重点を置き、生物多様性や植生構造、季節変化などの生態学的要因は十分考慮されていなかった。本研究では、植物や野生生物の多様性、植生の複雑性、自然の健全性などを含めた包括的な評価手法を提示し、これらの要素が利用者の心理的・身体的健康効果に影響を及ぼす可能性を示した。研究チームは、医療・公衆衛生・生態学・都市計画の連携により、生態学的価値の高い自然環境を活用した自然処方を推進することが、健康増進と生物多様性保全を同時に実現する重要な戦略になると提言している。

自然処方における生物多様性の重要性を示す新たな枠組み(Not all green space is equal: New framework highlights overlooked ecological factors in nature prescribing)

Abstract

Human health benefits associated with nature exposure are increasingly recognised in public health and environmental policy. However, most evidence linking nature and wellbeing relies on broad anthropogenic exposure proxies, including greenness indices, land-cover categories, and self-reported visit frequency, rather than ecological measures capturing biodiversity, habitat condition, or ecosystem functioning. Consequently, the ecological conditions that mediate health benefits, their exposure–response relationships, and the long-term sustainability of nature-based wellbeing interventions remain poorly understood. Here we examine how current research integrates human health, ecological integrity, and sustainability dimensions within nature-based wellbeing research. A targeted evidence synthesis confirms that most research is conducted in urban or human-modified environments and relies predominantly on coarse spatial proxies or categorical exposure contrasts, with limited incorporation of ecological quality, biodiversity, or environmental pressures. Critically, ecological costs and feedbacks associated with nature use, including habitat disturbance, visitor pressure, and infrastructure expansion, are rarely accounted for in assessments of health outcomes. We propose a one health sustainability framework that conceptualises nature-based wellbeing as an emergent property governed by ecological integrity, biodiversity-mediated pathways, environmental pressures, and long-term sustainability feedbacks. Extending one health beyond its traditional focus on zoonotic disease, this framework links human wellbeing outcomes to ecological condition and sustainability constraints, enabling assessment of exposure efficiency and the capacity of ecosystems to sustain health benefits under increasing demand. Embedding ecological integrity and sustainability dynamics within nature-based wellbeing research provides a basis for developing integrated indicators that can evaluate not only whether nature exposure benefits health, but also under what ecological conditions such benefits remain equitable and durable over time.
