Increased imperviousness alters watershed hydrology, shifting it from infiltration-dominant to runoff-dominant, leading to reduced groundwater recharge, higher runoff, increased peak discharge, and channel enlargement. In the United States, policy regarding stormwater management is predominantly focused on towns with populations greater than 10,000. However, any increase in impervious cover can negatively affect hydrology and water quality, and communities with populations smaller than 10,000 often lack the financial and technical resources to mitigate issues from impervious cover. This study examines changes in impervious cover in small towns and HUC-12 watersheds in eastern South Dakota between 2001 and 2019, alongside population changes from 2000 to 2020 in towns with populations under 10,000. Imperviousness changes were evaluated using the NLCD, and population shift was assessed using U.S. census data. A t-test was performed to compare changes over time, followed by linear regression and generalized additive model to examine the effects of population density dynamics and proximity to larger cities on changes in imperviousness. Results reveal significant demographic changes, with more than half of the towns studied experiencing population declines, while those closer to larger cities saw growth. Despite these population declines, many towns saw significant increases in imperviousness, highlighting that population change alone does not fully explain shifts in impervious surfaces and that other factors, such as land-use policies and socio-economic factors, play a significant role. Although small towns contributed modestly to overall watershed imperviousness, more than half (52 %) of these towns had already exceeded the 10 % threshold commonly associated with ecological impairment by 2019. Additionally, the average imperviousness in these towns rose from 9.3 % in 2001 to 12.7 % in 2019, highlighting the need for expanding the focus of stormwater policy beyond larger communities. Interestingly, while imperviousness significantly increased in small towns, most watersheds experienced a decline, and only 28.2 % of watersheds saw increases primarily among those near larger urban centers, underscoring complex spatial patterns in land use. These findings highlight the importance of addressing these challenges with finer-scale watershed delineations, localized management support, and strategies to enhance community resilience and improve water resource management in small towns.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"380 ","pages":"124996"},"PeriodicalIF":8.0,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

The results reveal a low awareness among owners' residents about the importance of sustainable maintenance, difficulties in the transfer of information between construction companies and managers, and the insufficiency of effective public incentives. Thus, the study highlights a gap in the integrated application of Life Cycle Sustainability Assessment in the construction sector, suggesting the need to develop more robust public policies and establish quantitative indicators to measure the economic and environmental benefits of these practices.

These limitations are driven by concerns about reduced swale infiltration capacity, which negatively impacts the effectiveness of green measures in managing runoff volumes. This study evaluates the spatial and temporal distribution of infiltration rates in a 30-m grass swale section using a Modified Philip-Dune infiltrometer and full-scale infiltration testing. Groundwater levels were continuously monitored by three piezometers adjacent to the grass swale to assess the impact of unsaturated zone depth on the swale infiltration capacity. Results showed that infiltration rates varied widely from 13 mm/h at the swale bottom to 98 mm/h on the right slope and highlighted the potential overestimation of swale capacity when relying only on point measurements of infiltration. Results from a full-scale infiltration test revealed an overall swale infiltration rate of only 4 mm/h, which is below the values recommended in the literature for swale applicability. A 52 % decrease in infiltration rates was observed between 2022 and 2024. Experimental results indicated that the grass swale had the capacity to recover its storage and managed a subsequent rainfall event within 15 h of the full draw-down.

Rice and eel co-culture (REC) systems have recently been used as an emerging integrated farming model that can stabilize grain yields and improve fertilizer availability. However, the influence of long-term REC system concerning the aggregation and health risk of ARGs in rice fields is still unclear. Here, we deciphered firstly the profile, potential of pathogenicity and mobility, and bacterial hosts for soil ARGs in the long-term REC system compared to the mono-rice (MR) culture system by collecting soil samples from 12 rice fields in Shanghai. The long-term REC system alleviated the accumulation of ARGs in soil, which is manifested in the abundance decrease of total ARGs and 11 ARG types (e.g., multidrug and aminoglycoside). The frequency of ARGs co-occurring with VFGs and MGEs was lower in the long-term REC system than in the MR system, indicating the lower pathogenicity and mobility potential for ARGs. The soil microbial community was identified to primarily drive the ARG discrepancy between the long-term REC and MR systems. In comparison with the MR system, long-term REC weakened the competitive advantage of ARG bacterial hosts, which might contribute to the decreased prevalence of antibiotic resistance. Overall, these findings uncovered the important role of long-term REC system in alleviating the accumulation of soil ARGs, providing theoretical support for antibiotic resistance risk control and sustainable agricultural strategic management.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"380 ","pages":"125099"},"PeriodicalIF":8.0,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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, there has been less work documenting how community social contexts evolve over time, and the ways they might influence collective mitigations pursued in partnership with professionals when addressing wildfire planning. We conducted 73 semi-structured interviews with 112 residents, emergency management professionals, government officials and members of community organizations in two Nevada County, California, communities to better understand how evolving elements of local social context influenced grassroots approaches to wildfire evacuation planning. Our results suggest that distinct risk factors, shared identities, landscape relationships, and interactions with outside professionals operating in each proximal community influenced divergent strategies that members were pursuing to address primary concerns about safe evacuation during fire. Respondents also articulated how their predominant focus on evacuation adaptations emerged over time, and through the legacy of historic decisions and interactions that increased saliency of evacuation concerns. Our efforts uncovered key roadblocks to the implementation of \"tailored\" evacuation adaptations in both communities (i.e., local evacuation routes or the development of 'safety zones'), including key uncertainties about the use of chosen mitigations, changes in agency support for evacuation planning, and integration of grassroots planning into existing systems for emergency management. Underlying all the above findings was a need to better understand or forecast ongoing transitions in the social makeup and functioning of both communities, including the exploration of tactics reflecting community members' adaptation needs or strengths. We utilize and expand existing frameworks for understanding community wildfire adaptation to make community-specific suggestions about the best ways to organize the collective evacuation adaptations being pursued in each community.
