The study was conducted for four years over a seasonal period of spring 2019 (February-March) to fall 2022 (September to October). For the exploration of maximum diversity at both sites, quadrats of 10 × 10 m were placed randomly. Ten soil, twelve anthropogenic, seven environmental and eight seasonal variables were used to assess their relationship with vegetation of both sites during four years of study. For statistical analysis, data was processed in the SPSS for LSD test and R Studio for Canonical Correspondence Analysis (CCA) and heat map preparation. A total of 84 plant species, belonging to 62 genera and 26 families, were identified in the Derawar region. Herbaceous plants comprised the majority, with 42 species, followed by grasses (22 species), shrubs (12 species), trees (7 species), and one sedge species. The protected site exhibited higher species diversity, with 76 species from 23 families, compared to the unprotected site, which had 49 species from 15 families. Species richness, Simpson index, and Shannon index showed significant declines in diversity from the protected to the unprotected site.","PeriodicalId":510399,"journal":{"name":"Polish Journal of Environmental Studies","volume":"38 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140743486","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}

Therefore, exploring the relationship between digital economy and carbon emissions in the sports industry holds great significance. Based on 2010-2021 panel data covering 30 provinces in China, the digital economy development level (DEL) and carbon emissions of the sports industry (CESI) are measured. Then, a two-way fixed effect model, threshold effect model and spatial Durbin model are used to examine the impact of the digital economy on the carbon emissions of the sports industry. The results show the following: (1) After multiple tests, the development of the digital economy has a significant inhibitory effect on the CESI; in other words, the development of the digital economy can drive the low-carbon development of the sports industry. (2) The influence of the development of the digital economy on the CESI has a nonlinear feature of an increasing marginal effect and a spatial spillover effect. (3) From the perspective of regional heterogeneity, the development dividend of the digital economy in the developed eastern region of China is greater than that in the less developed central and western regions, having a more significant impact on the low-carbon development of the sports industry. Therefore, it is necessary for China to speed up the construction of digital infrastructure, build an integrated layout of digital infrastructure, give full play to the radiating role of the digital economy, and implement differentiated development paths based on regional comparative advantages.","PeriodicalId":510399,"journal":{"name":"Polish Journal of Environmental Studies","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140747921","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}

The study aimed at recommending the most suitable probability distribution and efficient method of parameter estimation for each gauging site. Generalized extreme value, generalized logistic, Gumbel, generalized Pareto, and reverse Gumbel probability models are fitted to the annual peak flow/discharge. For each gauging site, the parameters of these distributions are estimated through L-moments, maximum likelihood, least squares, weighted least squares, and relative least squares methods. For each site, the probability models with a particular estimation method are ranked on the basis of goodness-of-tests and accuracy measures, and then the most suitable pair of model and estimation method is identified through a total rank. The results indicate that the generalized Pareto distribution is the best fit for Marala, Khanki, Qadirabad, and Punjnad, while the generalized extreme value distribution is the most suited for the Trimmu gauging site. As far as the estimation method is concerned, least squares and weighted least squares methods are more accurate for most of the gauging sites. Finally, for each gauging site, the best-suited probability model is used to estimate the annual peak flow and to construct associated confidence intervals for different return years.","PeriodicalId":510399,"journal":{"name":"Polish Journal of Environmental Studies","volume":"194 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140746587","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 this study, qualitative interviews were conducted with community members residing in regions characterized by substantial carbon emissions or high energy consumption. These interviews delved into their levels of awareness, attitudes, and willingness to engage in local carbon reduction initiatives through the utilization of carbon dioxide. Furthermore, community workshops and focus group discussions were organized to facilitate community participation, foster dialogue about potential carbon utilization projects and enabling the collection of their ideas and concerns. Additionally, in-depth case studies were undertaken by selecting specific communities (Astana and Almaty), allowing for a comprehensive examination of ongoing local initiatives related to carbon utilization. These initiatives encompassed a wide array of community-led projects, collaborations with local industries, and grassroots innovations, providing valuable insights into community-driven solutions for carbon reduction. The survey results revealed that respondents strongly agree that communities face significant challenges in implementing carbon reduction initiatives, with concerns about funding and pessimism about the opportunities for success.
