In this narrative review article, we ask why the setting of national park entry fees varies in practice, and we link this back to the underlying theory, the empirical academic literature, and practical realities. Park entry pricing strategies tend to differ considerably in higher and lower-income countries, reflecting practical realities of how to fund a national park system. Parks in higher-income countries are often free at the point of entry, consistent with the efficient pricing of global public goods. In contrast, differential pricing for local and foreign tourists is common in lower-income countries, an example of price discrimination that increases overall park revenues. We highlight a number of areas for further research. First, the concept of fairness and equitable access is an important practical consideration, linked to who benefits from visiting parks versus who pays, but much more attention needs to be paid to this in the literature. Second, while there is increasing recognition of the importance of green spaces for health and well-being, the literature largely ignores how health considerations might influence park entry fees, suggesting that more research is needed at the nexus of pricing, health and well-being, and equitable access. Finally, many lower-income countries that have a high dependence on foreign visitor fees to fund their national park systems are vulnerable to global shocks, suggesting research is needed into how to increase long-term sustainability of funding sources.</div></div>","PeriodicalId":29813,"journal":{"name":"Eco-Environment & Health","volume":"4 2","pages":"Article 100151"},"PeriodicalIF":0.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143936605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study develops a spatial visualization model to estimate carbon emissions in Southeast Asia using calibrated nighttime light data, with DMSP-OLS (Defense Meteorological Satellite Program Operational Linescan System) and NPP-VIIRS (National Polar-orbiting Partnership Visible Infrared Imaging Radiometer Suite) standardized through polynomial regression and machine learning to ensure consistency. Emissions in Southeast Asia increased by 2.51 times from 1992 to 2022, shifting from gradual to rapid growth. Validation against Open-source Data Inventory for Anthropogenic CO₂ (ODIAC) and Emissions Database for Global Atmospheric Research (EDGAR) shows strong agreement in high-emission urban areas but discrepancies in low-emission rural regions due to data sparsity and satellite sensor limits. Spatial analysis reveals that major Southeast Asian cities and their peripheries exhibit robust, sustained growth, while rural, less-developed areas show slower trends, highlighting persistent urban-rural disparities. These urban regions demonstrate a “circular economy advantage”, where per-unit-area carbon emissions steadily rise in economically advantageous zones. Despite high model accuracy, uncertainties persist due to variations in regional economic activities and the limitations of satellite-based emission proxies. Forecasts suggest elevated emission levels in major cities will continue, while changes in other areas remain relatively minimal. Consequently, achieving a low-carbon economy in Southeast Asia requires a top-down approach, emphasizing infrastructure enhancement, resource and energy optimization, and fostering a sustainable, circular socio-economic system.</div></div>","PeriodicalId":29813,"journal":{"name":"Eco-Environment & Health","volume":"4 2","pages":"Article 100150"},"PeriodicalIF":0.0,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143922725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 512,691 participants of the China Kadoorie Biobank cohort across 10 regions in China, we calculated the levels of greenness exposure based on satellite-retrieved Normalized Difference Vegetation Index (NDVI) data. Annual maximum NDVI (NDVI_max) values were estimated within 500 ​m and 1000 ​m buffers around the locations for the participants during the follow-up periods. Record linkages to healthcare databases provided incidence data of total CVD, ischemic heart disease and stroke during 2005–2017. Time-varying Cox proportional hazards regression was used to assess the associations between greenness exposure and CVD incidence. After 5.08 million person-years of follow-up, 148,032 incident CVD events were recorded. The overall average level of NDVI_max was 0.543 for all participants. We observed significant inverse associations of greenness with the incidence of CVD and its subtypes. Specifically, the hazard ratio for total CVD incidence was 0.976 (95% confidence interval: 0.958, 0.994) per 0.1 increase in NDVI_max within a 500 ​m buffer. As the 5 rural regions have achieved the WHO recommended greenness goal values, we compared the greenness levels in the 5 urban regions with the WHO's goal for greenness and found that, on average, 3.81% of total CVD incidence might be averted if the recommended greenness values could be achieved. Exposure to a higher level of greenness was associated with a lower risk of CVD incidence in Chinese adults.</div></div>","PeriodicalId":29813,"journal":{"name":"Eco-Environment & Health","volume":"4 2","pages":"Article 100148"},"PeriodicalIF":0.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143936603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of particular importance is the timely update of the National Biodiversity Strategies and Action Plans (NBSAPs) and/or National Targets aligned with the GBF before the sixteenth meeting of the Conference of the Parties (COP16) to the Convention on Biological Diversity. Upon comprehensive evaluation of updated NBSAPs of 47 parties and updated national targets of 126 parties, we proposed pathways that could better inform the updating processes. First, the essential elements of the goals and targets of the GBF applicable to national circumstances should be equivalently translated into national policies and instruments. Second, when specific national circumstances do not match with those essential elements, parties need to determine their own national biodiversity targets based on their situation but in a way that maintains and reflects the ambition of the GBF. Furthermore, the key factors that promote the success of biodiversity conservation are highlighted in terms of the target alignment with the GBF, the ownership enhancement, and the capacity building. We anticipate that these measures could facilitate immediate actions to update the NBSAPs to align with the GBF at the highest level while remaining cost-effectiveness.</div></div>","PeriodicalId":29813,"journal":{"name":"Eco-Environment & Health","volume":"4 2","pages":"Article 100147"},"PeriodicalIF":0.0,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143922958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
