Conservation agriculture practices (CAPs) have been promoted as a sustainable solution to improve soil health, enhance productivity, and increase farm income. However, research on the adoption and impacts of CAPs in Vietnam remains limited. This study aims to identify the determinants of CAPs adoption and assess its impacts on maize yields and net income in the Northwest mountainous region of Vietnam. The analysis is based on survey data from 400 maize-farming households. A multinomial endogenous switching regression (MESR) framework is employed to address selection bias. The findings indicate that the joint adoption of CAPs is facilitated by education of the household heads, total farmland area, farmers’ access to credit, interactions with extension agents, training on CAPs, proximity to cooperatives, participation in farmers' groups, and plot-specific characteristics. The impact analysis reveals that adopting CAPs—either individually or in combination—significantly improves maize yields and net income. The benefits are most pronounced when multiple practices are implemented simultaneously, underscoring the synergistic effects of CAPs. These results suggest that promoting the combined adoption of CAPs should be prioritized in the region. Policymakers and development practitioners are advised to focus on improving access to credit, strengthening extension services, expanding targeted training programs, fostering the formation of farmer groups, and raising farmers' awareness of their farmland characteristics and the benefits of CAPs.</div></div>","PeriodicalId":34794,"journal":{"name":"Environmental Challenges","volume":"19 ","pages":"Article 101143"},"PeriodicalIF":0.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143783695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study analyzes the changes in demographics, employment, and industrial structures in six Japanese BR municipalities using data from municipal statistics and national censuses for 2010, 2015, and 2020. Reference municipalities were selected for the comparative analysis based on certain criteria. The results indicate that all BR municipalities experienced population decreases ranging from −0.1 to −18.8 % after BR designation. Notably, five of these municipalities had slower depopulation rates than the reference municipalities. Conversely, five BR municipalities showed a relative decline in the number of employees compared to the references. The in-migration of retirees and families with children can be considered a possible reason for this paradox; however, the age-group analysis revealed that the influx of retirees and young families had no significant correlation between the BR and reference municipalities. Additionally, census data showed that tourism-dependent BR municipalities faced a decline in the tertiary sector due to the impact of COVID-19. The findings do not demonstrate a unified trend among Japanese BRs, suggesting that socioeconomic changes after BR designation cannot be generalized, largely because of the differing local contexts in Japan.

It intensifies urban heat island effects, degrades vegetation, and increases carbon emissions, particularly in rapidly developing regions. However, quantifying and mitigating these impacts remains a significant challenge, especially in cloud-prone areas where remote sensing data is often compromised. This study employs an advanced machine learning-based approach to assess the environmental impacts of industrial activities in Cilegon, Indonesia. Multi-source remote sensing datasets from 2014 to 2022 were analyzed. Integrating Landsat-8 for Land Surface Temperature (LST) and vegetation health (NDVI), GPM for precipitation, and ODIAC for carbon emissions. A hybrid filter approach enhanced data quality by reducing cloud-induced noise. An XGBoost model was developed to reconstruct LST, enabling a spatiotemporal assessment of industrial heat island (IHI) dynamics. The results reveal a staggering increase in carbon emissions, with Industrial Area 2 emitting 107 times more carbon than Industrial Area 1 due to coal-fired power plants. The industrial heat island effect extends to 1500 m, while carbon emissions significantly influence areas within 1000 m, exacerbating environmental stress. NDVI analysis indicates an 81.36 % decline in healthy vegetation in Industrial Area 2 between 2014 and 2019, emphasizing the severe ecological impact of industrialization. Seasonal trends show that La Niña-induced precipitation partially aids vegetation recovery, but its effects cannot counterbalance industrial degradation. Strong negative correlations were observed between NDVI and LST (-0.928) and NDVI and carbon emissions (-0.739), reinforcing the crucial role of vegetation in mitigating environmental damage. This study presents a data-driven framework to assess industrial environmental impacts using machine learning and enhanced satellite processing. The findings emphasize the urgent need for stricter emissions control, urban greening, and sustainable industrial planning to mitigate environmental degradation. Given the global rise in industrial emissions and urban heat stress, similar mitigation strategies are essential to enhance climate resilience and ecosystem sustainability.</div></div>","PeriodicalId":34794,"journal":{"name":"Environmental Challenges","volume":"19 ","pages":"Article 101141"},"PeriodicalIF":0.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data extracted from satellite images not only reveals historical changes in land use types but also serves as an essential input for predictive models concerning future urban physical development. In this research, Landsat satellite images from the periods of 1997–2007 and 2007–2017 were analyzed for Sari County.

LDN aims to balance reductions in land quality with initiatives to rehabilitate degraded land. However, due to budget constraints, it is not feasible to address all degraded land, necessitating strategic decisions about where to invest resources. This study, using Ethiopia as a case study, aimed to: (i) assess the long-term (1995 - 2024) land degradation trends, (ii) identify areas of net land loss or gain, (iii) prioritize regions and actions for addressing LDN, and (iv) evaluate the impact of Ethiopia's landscape management initiatives on LDN. The analysis of LULC changes and the observed landscape transformation across diverse agroecological zones yielded mixed results. While some areas, such as the dry Kolla and dry Weyna Dega regions, showed improvement, others, including the dry Dega and der Berha zones, experienced continued degradation. These variations affected the three main objectives of LDN: healthy ecosystems, food security, and human well-being. The ongoing landscape transformation, driven by LULC changes, underscores the need for more comprehensive strategies to mitigate further degradation and restore affected lands. Our findings regarding LDN trajectories, such as a 6 % reduction in degraded land between 2010 and 2024, suggest that national LDN implementation, through diverse Sustainable Land Management (SLM) practices, is essential for achieving the country's LDN goals. However, LDN outcomes varied across Ethiopia's agroecological zones, influenced by differences in environmental conditions, land use practices, and socio-economic factors. This highlights the necessity for tailored solutions, an understanding of varying restoration potentials, targeted resource allocations, and a focus on prioritizing the most vulnerable areas. Additionally, documenting both the successes and challenges of Ethiopia's restoration efforts, enhancing the effectiveness of its landscape management initiatives, and ensuring the long-term sustainability of its SLM practices are critical for achieving LDN.</div></div>","PeriodicalId":34794,"journal":{"name":"Environmental Challenges","volume":"19 ","pages":"Article 101137"},"PeriodicalIF":0.0,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
