Moreover, the frequency of these compound events has increased unevenly throughout the world and is expected to keep increasing in several regions. In this work, an assessment of compound drought and hot events in the summer months in Australia was made, using copula functions. Drought and hot conditions were identified by the Standardized Precipitation Evapotranspiration Index (SPEI) and the indices Number of Hot Days (NHD) and Number of Hot Nights (NHN) for the summer months, respectively. We analysed drought conditions in the current and the previous 1 to 3 months and the periods 1950–1978 and 1979–2020. The results show that the conditional probability of the occurrence of hot events given drought conditions is very high for the concurrent month in most of the study area, reaching 0.9 in some cases. Considering previous drought conditions, the higher probabilities are obtained in the southeastern region in December and in the north in February but, in most of the study area, these values are higher than for the case of non-drought conditions, pointing to an effect of previous drought conditions on hot events of up to 3 months. Moreover, an increased frequency of compound drought and hot events from the first to the second period was identified in more than half of the study area for lags of 1 and 2 months. We show that, although the conditional probabilities are mostly higher when computed with NHD, NHN is also affected by drought conditions, and should also be considered in this analysis, since nights can have a relieving contribution when impacts in health and wildfires are being analysed.","PeriodicalId":48496,"journal":{"name":"Environmental Research Communications","volume":"31 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140311355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

In this study, the spatial distribution patterns of nitrogen and phosphorus in sediments were studied in the riverside and lakeside wetlands of Dongting Lake, a typical river-connected lake. The results showed that the nitrogen and phosphorus concentrations in the surface sediments were higher than those in the subsurface sediments in both the riverside and lakeside wetlands. In addition, the concentration of total nitrogen (TN) of lakeside wetlands in the surface sediments was higher than that of riverside wetlands, whereas the concentration of total phosphorus (TP) did not differ between the two wetland types. In the surface sediments, there were significant positive correlations between the TN and TP concentrations in the riverside wetlands (<italic toggle=\"yes\">p</italic> &lt; 0.05), but no significant correlation in the lakeside wetlands (<italic toggle=\"yes\">p</italic> &gt; 0.05). In riverside wetlands, the nitrogen and phosphorus concentrations showed strong spatial dependence. However, in the lakeside wetlands, the spatial dependence of NO₃\u0000⁻-N was strong, that of NH₄\u0000⁺-N was moderate, and that of TN and TP was weak. This study shows that both hydrology and vegetation cause differences in the distribution of nutrients in the sediments. The results obtained from this investigation clarify the differences of sediment nitrogen and phosphorus distributions in the two types of wetlands and provide a technical reference for the management of different wetland types.","PeriodicalId":48496,"journal":{"name":"Environmental Research Communications","volume":"47 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140311032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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, its effects on nutrient uptake, soil microbiota, and rice yield remain unclear. Herein, we designed a double-cropping system with different fertilization treatments to determine their contributions to paddy soil agroecosystem and rice yield. Soil samples were collected before planting the early rice, after harvesting early rice, and after harvesting the late rice. Soil physicochemical properties, and rice yield, and rice nutrient (total nitrogen, phosphorus, and potassium contents) were determined. Variation of soil microbiota were also determined by high-throughput sequencing. We found that soil potassium content significantly improved during the planting process (P &lt; 0.05), while rice phosphorus displayed significant variation under fertilization (P &lt; 0.05). Notably, late rice yield was significantly higher than early rice yield (P &lt; 0.001) after fertilization treatment. Furthermore, rice yield was positively correlated with available soil phosphorus (P &lt; 0.05), indicating that fertilization promoted phosphorus uptake. Organic fertilizer altered the soil microbiota and increased <italic toggle=\"yes\">Chloroflexi</italic> phyla abundance, while organic fertilizer combined with a compound microbial agent increased the diversity of soil microbial communities. A partial least squares path model revealed that fertilizer treatment directly positively affected rice yield by influencing phosphorus uptake and Shannon index (P &lt; 0.01).

This paper studies the impact and mechanism of public environmental participation (PEP) on FDI. The results show that PEP has a significant negative impact on the FDI inflow of enterprises. Hindrance effect of PEP on enterprise FDI is more obvious in economically developed eastern regions, coastal cities and first-tier cities. PEP has a greater impact on FDI in high-tech industries. The economic growth target has a restraining effect on China’s environmental protection, weakening public supervision of FDI. The constraint of economic growth targets increases the pressure to develop the economy, and weakens the inhibitory effect of PEP on corporate FDI. This study provides important empirical evidence for improving China’s environmental governance system and high-quality utilization of foreign investment.","PeriodicalId":48496,"journal":{"name":"Environmental Research Communications","volume":"18 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140001725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Herein, two low-range compact vehicles were chosen and compared: one powered by combustion of gasoline, and the other by electric energy stored in batteries. Historical data and trend projections, according to inflation and prices evolution, are taken into consideration. The developed model may help to select adequately a new vehicle, according to the user’s needs. A good choice depends strongly on the usage and traffic conditions, the electric vehicle being suitable for large weekly driving distances and heavy traffic, whereas the gasoline vehicle is preferred for short distances and light traffic.

Reducing meat consumption is essential to mitigate climate change. Behavioural nudges, which present structured choices to citizens, have been increasingly used to reduce meat demand. But they face ethical challenges and limits when scaling up. We test if encouraging people to reflect after nudging improves the effectiveness of a nudge. We design and administer a novel randomised controlled trial in a German university cafeteria, lasting for five weeks (<italic toggle=\"yes\">N</italic>\u0000_{\u0000<italic toggle=\"yes\">participants</italic>\u0000} = 129<italic toggle=\"yes\">,N</italic>\u0000_{\u0000<italic toggle=\"yes\">meals</italic>\u0000} = 645). In week 1, we measure baseline dietary behaviours. In week 2, we introduce a labelling nudge in the cafeteria. Subsequently, in weeks 3 &amp; 4, we assign participants randomly to three experimental conditions: a control group that continues to receive the labelling nudge and two treatment groups that get the labelling nudge with an opportunity to reflect, either on the nudge (nudge+ 1) or their own preferences (nudge+ 2). All treatments are discontinued in week 5. In the pooled sample, controlling for period fixed effects, we find that the labelling nudge is not associated with meaningful changes in meat-demand over time. Nonetheless, being encouraged to reflect reduces meat-demand significantly compared to the nudge—the nudge+ 1 reduces chances of buying a meat-based item in the cafeteria by 5% (<italic toggle=\"yes\">μ</italic> = −0.25, 95% CI = [−0.49,−0.36]) whereas the nudge+ 2 reduces it by 7% (<italic toggle=\"yes\">μ</italic> = −0.35, 95% CI = [−0.61,−0.08]). These treatment effects attenuate when the interventions are discontinued. We recommend that combining reflection with nudging can improve the uptake of climate-friendly diets, at least in the short-term.","PeriodicalId":48496,"journal":{"name":"Environmental Research Communications","volume":"45 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140009073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 places its focus on wildfires in two regions of Alberta, Fort McMurray and Slave Lake, in Southwest Canada. For the simulation of wildfire spread, an adapted fire propagation model was employed, incorporating MODIS datasets such as land surface temperature, land cover, land use, and integrated climate data. The pixels were classified as burned or unburned in relation to the 2011 Slave Lake wildfire and the initial 16 days of the 2016 Fort McMurray wildfire, utilizing defined starting points and the aforementioned specified datasets. The simulation for the 2011 Slave Lake wildfire achieved an weighted average precision, recall, and f1-scores of 0.989, 0.986, and 0.987, respectively. Additionally, macro-averaged scores across these three phases were 0.735, 0.829, and 0.774 for precision, recall, and F1-scores, respectively. The simulation of the 2016 Fort McMurray wildfire introduced a phased analysis, dividing the initial 16 days into three distinct periods. This approach led to average precision, recall, and f1-scores of 0.958, 0.933, and 0.942 across these phases. Additionally, macro-averaged scores across these three phases were 0.681, 0.772, and 0.710 for precision, recall, and F1-scores, respectively. The strategy of segmenting simulations into phases may enhance adaptability to dynamic factors like weather conditions and firefighting strategies.","PeriodicalId":48496,"journal":{"name":"Environmental Research Communications","volume":"19 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139755090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Recent research suggests that preserving mangrove forests can offer a cost-effective strategy for mitigating CO₂ emissions. However, extensive deforestation has placed mangrove ecosystems under severe global threats. Currently, the assessment of mangrove restoration outcomes, particularly regarding soil carbon stocks, is inadequate. Therefore, this study aims to investigate the impact of restoration on soil organic carbon (SOC) in Shwe Thaung Yan, Ayeyarwady coastal region of Myanmar. The study aimed to quantify and compare carbon stocks in different soil layers, examine the carbon sequestration potential of various mangrove species, and evaluate the effectiveness of mangrove restoration efforts. Soil samples were collected in 2015 (pre-restoration) and 2021 (post-restoration) at various soil depths and analyzed for SOC concentration, organic matter content, and bulk density using the Loss on Ignition (LOI) procedure. Significant changes in soil properties were observed between 2015 and 2021, with higher SOC and carbon concentrations observed in 2021. The average soil carbon stocks in 2021 (1954.43 ± 33.24 Mg C ha⁻¹) were approximately 2.7 times higher than the estimated carbon stocks in 2015 (732.26 ± 6.99 Mg C ha⁻¹). Furthermore, the study revealed variations in SOC accumulation among different soil depths, with higher carbon stocks found in the upper soil layers. This study highlights the positive impact of mangrove restoration on SOC accumulation and emphasizes the significance of considering soil carbon dynamics in restoration initiatives. The findings offer valuable insights for the conservation and management of mangrove ecosystems, especially concerning their potential for carbon sequestration and their contribution to mitigating climate change.","PeriodicalId":48496,"journal":{"name":"Environmental Research Communications","volume":"12 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139755162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
