The investigation focused on 59 selected highland locations within the region. Using the De Martonne climate classification, projections were made for four future periods (2040, 2060, 2080, and 2100) under two scenarios: SSPs 245 and SSPs 585. The outcomes of the study indicate that the highlands under scrutiny are susceptible to substantial effects from global climate change. Notably, these climatic alterations are expected to become evident within the next two decades, predominantly manifesting as a shift towards arid climate classifications. These shifts are anticipated to have a profound impact on the composition and diversity of species in the highland ecosystems. Based on the findings, it is advisable to consider interventions for the most climate-sensitive highland areas, such as facilitating the migration of species adapted to the new climate conditions and implementing initiatives to enhance species diversity. These efforts could help mitigate the potential loss of species and populations resulting from climate change.</p></div>","PeriodicalId":56021,"journal":{"name":"Anthropocene","volume":"46 ","pages":"Article 100432"},"PeriodicalIF":3.6,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140122983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Past work in the upper midwestern United States, particularly in areas of moderate relief, has shown that increases in water and sediment fluxes associated with agricultural development have dramatically altered river dynamics. Less is known about how agriculture has affected river dynamics, particularly rates of lateral migration, in relatively low relief landscapes of the Midwest shaped by glaciation during the Wisconsin Episode. This research examines rates of lateral migration of a channel bend along a lowland meandering river in Illinois, USA before and after agricultural development. The rate of lateral migration prior to agricultural development is estimated through dating of carbonaceous material within lateral-accretion deposits underlying distinct meander scrolls. The rate of lateral migration after agricultural development is determined from analysis of changes in river-channel position determined from survey records, aerial imagery, and digital elevation data. Average rates of migration before and after agricultural development are similar, suggesting that agricultural development has not substantially affected rates of lateral migration of the river. Some accelerated movement occurred locally following agricultural development, but this movement cannot be definitively tied to landscape transformation. Possible factors responsible for the lack of sensitivity of the river system to agricultural development include high resistance of the cohesive, tree-lined riverbanks to erosion and the low bankfull stream power per unit area of the modern river. From a management perspective, the study highlights the importance of bank vegetation in maintaining channel stability in low-relief agricultural landscapes.</p></div>","PeriodicalId":56021,"journal":{"name":"Anthropocene","volume":"45 ","pages":"Article 100429"},"PeriodicalIF":3.6,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2213305424000067/pdfft?md5=0ad5dbb5606839765b3cc73adc86a7b9&pid=1-s2.0-S2213305424000067-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139719344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aside to protecting property and people, SWBE provides benefits for human well-being and biodiversity. Its use remains modest in cities, where the presumed benefits are important in a context of biodiversity crisis and warming. Negative public perceptions have been identified as one barrier to the dissemination of NBS. This article studies how environmental expertise influences perceptions and values associated with SWBE, and how the possible differences in perceptions and values induced by knowledge contribute to hindering or promoting the dissemination of these solutions. We carried out an original interdisciplinary study based on a sociological survey and ecological field measurements to characterize: (1) the perceived value that actors associate with several riverbanks equipped with different protection structures (green, hybrid, or gray) according to their level of expertise in the aquatic environment; (2) the interactions between these perceived values and the ecological values measured by restoration ecologists; and (3) the perceived benefits and drawbacks of SBWE techniques. Our results show that the ecological and social benefits provided by NBS are recognized by all, whatever their level of knowledge. Despite this consensus, we observed different hierarchies of value associated with bank protection structures among the surveyed actors, depending on their level of environmental expertise (some prioritising ecological values, others relational values), and these could hinder the dissemination of NBS. The most tangible obstacle to the dissemination of NBS in urban areas relates to the risk perceptions of lay people, who experience a higher sense of vulnerability than they do with traditional gray solutions.</p></div>","PeriodicalId":56021,"journal":{"name":"Anthropocene","volume":"45 ","pages":"Article 100424"},"PeriodicalIF":3.6,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2213305424000018/pdfft?md5=fb9c2975a009d84b9ba03671c7f6f541&pid=1-s2.0-S2213305424000018-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139549331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Together saltwater intrusion and sea level rise (SWISLR) create substantial changes to the social-ecological systems situated along the coastal plain. Many scholars and practitioners are engaged in studying and managing SWISLR impacts on social, economic, and ecological systems. However, most efforts are localized and disconnected, despite a widespread desire to understand this common threat. In addition to variable rates of sea level rise across the U.S. outer coastal plain, differences in geomorphic setting, water resources infrastructure and management, and climate extremes are resulting in different patterns of saltwater intrusion. Understanding both the absolute magnitude of this rapid environmental change, and the causes and consequences for its spatial and temporal variation presents an opportunity to build new mechanistic models to link directional climate change to temporally and spatially dynamic socio-environmental impacts.

Period Ⅰ (1670s–1800s) corresponds to a phase of limited anthropogenic activity reflected by the lowest ΣPAH₁₆ concentrations, mainly from biomass combustion and petrogenic processes. Along with pronounced deforestation due to wildfires documented in the pollen record, a similar decrease in PAHs suggests that PAHs were most likely generated by natural sources around Lake Issyk-Kul during this period. Period Ⅱ (1800s–1930s) reflects increasing agricultural activities with fluctuations in various PAH concentrations.

However, natural factors still mainly controlled changing lake levels before the 1930s. Period Ⅲ (1930s–1970s) corresponds to rapid development of agricultural activities, inferred by slight increases in ΣPAH₁₆ concentrations dominated by coal-derived PAHs and a considerable increase in ΣOCP₁₈ concentrations. Concentrated agricultural activities around Lake Issyk-Kul significantly influenced environmental changes in grain size and water level in the lake. Period Ⅳ (post-1970 s) corresponds to intensive industrial and urban activities, including a 10-year economic depression (1990s–2000s), characterized by the highest ΣPAH₁₆ concentrations mainly from petroleum combustion followed by a sharp drop after the 1990s as the dissolution of the Soviet Union.

Land ‘preservation’ is an effective means of protecting habitat, but isolation of preserved parcels can limit their effectiveness. The trade-off between land preservation and conservation requires that we consider land use strategies in a global context and as complementary of one another. Most assessments for increasing land conservation are based on vegetative and wildlife inventory, where far fewer assessments are based on soils or belowground accounting. Herein, we present a soil based perspective that could be useful in evaluating the capacity for different land management strategies to meet broader conservation goals, including 30 by 30 and provide a focus on forest management to demonstrate our approach. Our soils-based assessment of different land-use practices suggests that land management practices that cause minimal soil disturbance, generate minimal bare soil, and exhibit a dominance of native species would be effective at achieving meaningful land conservation benefits while continuing to meet human resource needs. Incentivizing conservation oriented land management practices could dramatically accelerate our ability to achieve large scale conservation objectives such as 30 by 30.</p></div>","PeriodicalId":56021,"journal":{"name":"Anthropocene","volume":"45 ","pages":"Article 100423"},"PeriodicalIF":3.6,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2213305423000565/pdfft?md5=56f012504dd6172d45f09566e31a5191&pid=1-s2.0-S2213305423000565-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138839354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
