Core Viewpoint - The recent study from Sun Yat-sen University highlights the significant role of greenspace in mitigating the global disease and economic burdens associated with non-communicable diseases (NCDs) [4][6]. Summary by Sections Non-Communicable Diseases (NCDs) - NCDs are the primary threat to global public health, causing 42 million deaths in 2021, which accounts for 75% of total global deaths [6]. - It is projected that from 2011 to 2030, NCDs will result in over $30 trillion in economic losses globally, imposing heavy burdens on families, healthcare systems, and society [6]. Importance of Greenspace - Greenspace, including forests, parks, and gardens, plays a crucial role in human health and disease prevention [6]. - Increased exposure to greenspace is associated with a reduced risk of various NCDs, such as cardiovascular diseases, diabetes, cancer, and mental health issues [6]. - The benefits of greenspace may stem from ecological, biological, psychological, and social pathways, including reduced air pollution and enhanced social cohesion [6]. Research Limitations and Gaps - Previous studies on the relationship between greenspace and NCDs have been limited to specific geographic areas, restricting the applicability of findings to broader populations [7]. - There is a lack of comprehensive research quantifying the potential health and economic benefits of increasing greenspace on a global scale [7][8]. Key Findings of the Study - The study analyzed data from 204 countries/regions between 2000 and 2021, using mixed-effects regression models to assess the association between greenspace and NCD-related mortality and disability-adjusted life years (DALYs) [8]. - Results indicate that larger greenspace areas correlate with lower burdens of NCDs [8]. - If greenspace had been maintained at optimal levels over the past two decades, it could have potentially prevented 1.66 million NCD-related deaths and 37.68 million DALYs, saving nearly $10 billion [8]. Implications for Policy - The findings provide invaluable information for policymakers and practitioners, suggesting that greenspace initiatives should be integrated into national policy-making and resource allocation to alleviate the disease and economic burdens of NCDs globally [10].
