Climate change is increasingly recognized as one of the most pressing global challenges of the 21st century. In South Africa, climate-induced extreme weather events have become more frequent, intense, and unpredictable, posing significant threats to humanity, ecosystems, and the economy. Therefore, there is an urgent need to better understand the trends and impacts of climate-induced extreme weather events in South Africa to inform evidence-based policy and decision-making. This study examines the trends and impacts of climate-induced extreme weather events in South Africa over the period 1920 to 2023. Using a comprehensive analysis of historical data, and scientific literature, the study identified significant trends (p < 0.05) in the frequency of climate-induced weather events. The results reveal a general increase in the frequency of most extreme weather events, with notable spikes in specific decades. For instance, the 2011–2020 decade recorded the highest number of extreme weather events, totalling over 1,800. However, there is a spatial variation in the frequency of occurrence of these events across provinces, with the Western Cape province having the highest frequencies, while the North West Province has the lowest. The findings highlight the significant socio-economic and environmental impacts associated with such climate-induced extreme weather events, including infrastructure damage, agricultural losses, water scarcity, and adverse health effects. The study underscores the critical need for robust climate adaptation and resilience strategies to address the escalating risks posed by, among other weather extremes, floods, droughts, tornadoes, heatwaves, hailstorm, snow and frost, and wildfires. The increasing prevalence and severity of these events call for immediate and coordinated action to enhance South Africa's preparedness and response capabilities in the face of a changing climate.

Tourism activities on small islands are developed to obtain economic benefits. However, challenges due to limited land-carrying capacity often lead to environmental degradation. This study explores the potential of implementing a Payment for Ecosystem Services (PES) program in Gili Matra, North Lombok, Indonesia, to balance tourism and conservation. Utilizing a mixed method with both quantitative and qualitative research approaches, this study examines the demand, supply, and public policy interventions necessary for a successful PES program. The Contingent Valuation Method was employed to assess the willingness to pay and willingness to accept among international and domestic tourists, tourism entrepreneurs, and fishing households. The results indicate that domestic tourists are willing to pay an average of Rp 35,000 (approximately US$ 2.15) per visit, while foreign tourists are willing to pay US$21.46 per visit. Entrepreneurs express willingness to pay a monthly fee of IDR 52,000 (approximately US$ 3.2). On the supply side, fishing households are willing to accept Rp 1,326,000 (approximately US$ 81.51) per month for coral reef conservation efforts. The findings suggest the feasibility of adopting PES in small island tourism to contribute to sustainable tourism and support SDGs 14 and 15. The study recommends implementing a mandatory PES scheme through regional regulations and integrating fees into admission tickets via a digital platform for effective management.

Scholars have long discussed various transportation tools as key factors in building sustainable societies by either generating or reducing environmental hazards. We examine effects of road upgrades on household waste management, an environmental outcome that is less explored in prior research, yet particularly relevant in the Global South. We use the latest census and health survey data from Benin to estimate how household waste disposal practices in northern Benin were affected by a major road project that began to be used in 2011. We use difference-in-differences regression models to estimate the effect of the road project by comparing areas with and without road upgrades, before and after the construction. Results show that this road project led to a statistically significant and sizeable increase in the sustainable, service-based collection of household waste in communities that were involved in the project and were historically less developed. The positive environmental effects were concentrated among rural communities. These results illustrate that improvements in transportation infrastructure facilitate environmental management—specifically waste management in this paper—by making the delivery of environmental services more effective and accessible to ordinary people. Overall, this paper provides policy recommendation for politicians and planners to consider transportation as an integral part of sustainable social and economic development.

This study conducts a life cycle assessment (LCA) of tea production and consumption in Türkiye, the world leader in per capita tea consumption. Aiming to identify environmental hotspots and propose sustainable solutions, a cradle-to-grave LCA was performed using CCaLC2 software, CML methodology, and the Ecoinvent 3.0 database. It covers cultivation, processing, transportation, and consumption stages, focusing on key environmental indicators like carbon footprint and acidification potential.

The results reveal that consumption dominates the environmental footprint (91%) due to energy-intensive brewing methods. Cultivation and transportation contribute minimally (4% each). This highlights the need for promoting energy-efficient brewing practices and consumer adoption of renewable energy sources. The study also explores the environmental implications of different waste management strategies. Composting emerged as the most beneficial approach for reducing the carbon footprint and photochemical oxidants creation, while incineration might be preferable for other impact categories.

This study underscores the importance of addressing energy consumption during tea brewing and encouraging renewable energy use among consumers. Additionally, it promotes composting as a crucial waste management strategy for a more sustainable tea value chain in Türkiye. These findings offer valuable insights for policymakers, industry players, and tea drinkers to make informed decisions that minimize environmental impact.

Plastic pollution is one of the most threatening environmental and public health problems. In 2023, total plastics production reached 322 million metric tons, from which more than 50% are thrown into the oceans, rivers, or lakes. Plastics are recalcitrant compounds that remain in nature and the built environment for decades due to their durability and stability. Accumulation of plastic has been reported even inside human's body as micro and nanoplastics can enter the food chain. Given the relevance of plastic waste pollution for our society and ecosystems, we analyzed the literature on plastic degradation from 1974 to 2025 and conducted a bibliometric analysis focused on physicochemical and microbial treatments for plastics. Our results showed that plastics' hydrophobicity and crystallinity are the main polymer degradation challenges. Polyethylene and polypropylene are the most researched plastics. Microbial degradation is frequently chosen for plastics degradation, while UV oxidation has been the most used physicochemical treatment. Hybrid plastic degradation treatments must be conducted from a transdisciplinary perspective. In this review, we synthesize the main techniques used to characterize plastics and microbial strains highly studied for plastics degradation. The field of plastic degradation is quickly unfolding and expanding its boundaries.

Cities in the Global South face amplified consequences of climate change due to rapid urbanization, which is predominantly informal and lacks basic infrastructure and emergency support systems. The worst affected sections are those living in informal settlements, generally located in the city's floodplains. The lack of or lag in the state's response to flood hazards creates a need for urban dwellers to adapt to these recurring disturbances. However, there is limited understanding of the implications of these localized interventions for overall urban resilience and how they interact with state-level adaptation efforts. This study explores two layers of resilience phenomena: urban form resilience and the adaptive response of different stakeholders within the urban form. Taking case study of Surat, a city situated on the western ghats of India, the study assesses urban form resilience and the patterns and costs of adaptation through a Rapid Visual Survey (RVS). The findings reveal that formal urban areas have higher resilience scores, while informal settlements exhibit lower resilience scores but more individual adaptation. Individual households alter their physical form by taking measures such as raising the plinth, raising the porch area, constructing a protection wall on the entrance, and constructing a mezzanine floor to cope with recurring flood hazards. However, the cost of these individual adaptations is significantly high for an adapting household as compared to the per household cost of state-led adaptation. The study provides a context-specific input to the ongoing discourse on collaboration between top-down and bottom-up efforts for a resilient and sustainable urban environment.

Agricultural land consumption caused by expropriation for infrastructure and development projects is an ongoing process in developing countries attributed to population growth and economic considerations. Rapid urban development in cities like Duhok in the Iraqi Kurdistan Region IKR has converted fertile lands into metropolitan areas in the past three decades. This development has resulted in numerous environmental impacts, particularly the decline in groundwater levels. This study investigates the relationship between this phenomenon and groundwater depletion in Semel and Zakho districts within Duhok governorate. The analysis spans from 1992 to 2023 for land consumption data and from 2004 to 2022 for groundwater decline data. The study utilized document analysis, field observation, and analysis of plans and drawings, using Geographic Information Systems GIS and Google Earth imagery, to examine the process's impact within the specific context. The findings reveal a significant increase in non-agricultural areas and a decline in agriculture over the studied period, demonstrating the sharp reduction in groundwater levels due to agricultural land consumption through expropriation.

The small-scale fishery value chain faces challenges worldwide, from pre-catch, catch, and post-catch to consumption. Regarding the blue crab (Callinectes spp.), an important resource for traditional communities in Laguna (Santa Catarina, Brazil), it is no different. This study analyzes the blue crab value chain in Laguna from the perspective of Local Agri-Food Systems (LAS), a governance proposition that mobilizes the Sustainable Territorial Development approach. Primary data was collected through (i) direct observation and (ii) 20 semi-structured interviews with small-scale fishers and local traders. Secondary data was obtained through documentary research, including a review of the legislation on the health and commercialization aspects of artisanal Products of Animal Origin (PAO) and an analysis of data from the Santa Catarina State Fishing Activity Monitoring Project (PMAP-SC). The interviews were organized using the ranking technique and analyzed by the actors' taxonomy. The results suggest little interaction between public managers (regulatory, development, research, and extension agencies), fishers, and end consumers. The main difficulties include financial issues, lack of technical support, and devaluation of the artisanal product and the profession. The systems' feasibility requires mechanisms to encourage management, including financial independence, increased family income, economic incentives, and the value of local products. The balance between society and the community will define the territorial economy, considering the importance of historicity and collective memory in organizing local production systems. Reciprocity is fundamental, as is the construction of collective knowledge and the ability of the blue crab value chain actors to learn together.

While road infrastructure expansion continues transforming Sub-Saharan Africa, research remains fragmented between socioeconomic and environmental impact assessments. Through a systematic review of 255 peer-reviewed articles from 6189 papers (1984–2024) examining road development impacts, we reveal patterns in research focus, methodological approaches and road development impacts. Approximately 58% of published studies on road impacts examined socioeconomic impacts, 37% investigated environmental effects, while only 5% investigated both socioeconomic and environmental impacts simultaneously. Geographically, most studies were conducted in five countries (Ethiopia, South Africa, Nigeria, Kenya, and Tanzania), with 78% of these studies published after 2014. Furthermore, our analysis found a significant relationship between foreign direct investment (FDI) and environmental degradation, with countries experiencing a 34% increase in observed negative environmental road impacts for each standard deviation increase in FDI (β = 0.34, p < 0.05). This effect tended to be particularly strong in countries with weaker environmental governance. Moreover, countries with higher Human Development Index (HDI) scores demonstrated 28% fewer negative environmental impacts, suggesting development status significantly influences environmental management capacity. Consequently, we suggest assessing road effects from an interdisciplinary perspective to better understand road-induced tradeoffs and offer informed, evidence-based planning for road infrastructure development that minimizes environmental costs and maximizes socioeconomic benefits.

This study explores the intricate relationships among environmental quality, public finance indicators, and socioeconomic variables in OECD countries, using Machine Learning (ML) techniques for the period 1990–2021. The research uniquely identifies key factors influencing renewable energy consumption (REC) by incorporating various public finance indices, macroeconomic fundamentals, trade measures, and socio-economic variables. By emphasizing the role of public debt policies, the study uncovers their significant yet complex and non-linear influence on renewable energy adoption. Unlike existing studies, this research utilizes Neural Networks (NN), a state-of-the-art ML technique, to generate robust and reliable outcomes. This methodological innovation sets the study apart by offering more accurate feature importance scores compared to traditional econometric methods. The findings advance our understanding of the crucial role that public finance plays in achieving Sustainable Development Goals (SDGs), particularly SDG-7, and underscore the necessity of effective public debt management for fostering environmental sustainability. Policy implications drawn from the results provide actionable recommendations for governments to enhance REC adoption while achieving broader environmental goals.
