Inputs considered included natural capital and control variables such as temperature, precipitation, soil moisture, and natural disturbances, among others, that impact ecosystem service production. Inefficiency was modeled as a function of factors such as ownership, forest productivity, and natural disturbances. We utilized forest plot-level data obtained from the Forest Inventory and Analysis (FIA) program between 2008 and 2019. Our results indicated that ecosystem service production increased with higher levels of natural capital, higher temperatures, mesic soils, the presence of oaks, and damage caused by abiotic factors. We found evidence of technical inefficiency in the simultaneous provision of ecosystem services. From an input perspective, our findings revealed that, on average, 15.9% more input is used due to technical inefficiency in the Cross Timbers region. Specifically, private ownership and damage caused by abiotic factors resulted in excess input use of 16.4% and 14.3%, respectively, due to technical inefficiency. Managing the encroachment of invasive species like eastern redcedar can enhance ecosystem service production in the region, despite the high implementation costs. Collaboration among multidisciplinary extension professionals can help create comprehensive land management plans for the Cross Timbers, while landowners can also utilize cost-share programs to lower management expenses.</p></div>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":"75 2","pages":"330 - 340"},"PeriodicalIF":2.7,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142455241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing literature often neglects the impact of rural residents' digital literacy and policy cognition on their adoption of eco-friendly behaviors. In the digital age, rural residents can efficiently access and utilize ecological information, deepen their policy cognition, and consequently, become more actively involved in ecological protection through enhancing their digital literacy. This enhancement is crucial for ensuring the smooth implementation of rural ecological policies at the grassroots level, thereby providing a strong impetus for the further development of rural ecological protection. Therefore, based on survey data from 851 respondents in four counties and cities in Hainan Province, this paper uses the Ordered Probit model to analyze the impact of digital literacy on rural residents' adoption of eco-friendly behaviors, supported by theoretical mechanism analysis. The results indicate that: (1) Digital literacy enhances the adoption of eco-friendly behaviors among rural residents; (2) The mechanism analysis shows that digital literacy promotes such adoption through improved policy cognition. Consequently, the government should actively promote digital technology education and training to improve rural residents' digital literacy. Therefore, targeted digital skills training policies should be developed according to the individual characteristics of rural residents. Additionally, promoting digital literacy to improve policy cognition will likely lead to greater engagement in eco-friendly behaviors.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142455243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the effect of forest use changes on water browning in Finland, considering the effects of global pressures. Our goal was to find the ecosystems and geographic areas that are most sensitive to environmental pressures that increase the loading of DOM. We were also looking for land use strategies that decrease browning. We combined mathematical watershed modelling to scenarios of climate change, atmospheric deposition, and forest use change. Changes included scenarios of forest harvest and protection on forest, that were derived from European Union’s regulation. The study area covered 20 watersheds from south to north of Finland. In northern Finland brownification continue. In southern Finland global influence (atmospheric deposition, climate change) seem to weaken, giving more space for local forest use change having an influence on brownification. Forest use change was more influential in river basins dominated by organic soils than in mineral soils. Extending forest protection decreased brownification especially in areas where the influence of atmospheric pressure is decreasing. When forest protection is planned to provide a carbon storage and sequestration potential and to favor biodiversity, it has favorable effect on surface water quality as well.</p></div>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":"75 2","pages":"205 - 220"},"PeriodicalIF":2.7,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00267-024-02058-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142455245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the PA strategy often fails to achieve its objective – preserving biodiversity and ecosystem services. In addition, the expansion of PA areas could replicate and amplify historical injustices such as forced evictions, state-led physical violence, assimilation of culture and loss of traditional ecological knowledge, affecting communities’ livelihood, quality of life and rights. There is an increasing consensus that the post-2020 biodiversity conservation framework should be rights-based and sensitive to the role and contributions of local communities towards achieving the PAs’ targets. India’s Forest Rights Act (FRA) 2006 may be considered a useful framework for biodiversity conservation in the context of this new conservation vision. It puts local people at the centre stage, making them active participants in designing and managing conservation. PAs following ‘fortress conservation’ approach were based on the flawed idea that human interference endangers biodiversity and therefore habitats should be preserved by force if required. Such an idea contradicts the recent understanding that ecosystems once perceived as ‘wilderness’, have been transformed by people. PAs undermine the intricate and intertwined relationship of humans with their immediate ecosystem. The conservation model proposed by FRA 2006, on the other hand, recognises local communities as an integral part of ecosystem and thereby acknowledges people’s rights and agency in conservation. It ensures locals’ equitable benefits from economic activities, and provides equitable opportunities to participate in decision-making. Though various provisions under FRA empowered local people in conservation, it faces various challenges during the implementation on the ground.
