Integrating a multi-variable scenario with Attention-LSTM model to forecast long-term coastal beach erosion

Beach erosion is an adverse impact of climate change and human development activities. Effective beach management necessitates integrating natural and anthropogenic factors to address future erosion trends, while most current prediction models focus only on natural factors, which may provide an incomplete and potentially inaccurate representation of erosion dynamics. This study enhances prediction methods by integrating both natural and anthropogenic factors, thereby enhancing the accuracy and reliability of erosion projections. By extracting historical shorelines through CoastSat model from 1986 to 2020, we develop multivariable scenarios with Attention-LSTM model to predict the regional impacts of natural and anthropogenic factors on erosion to sandy beaches along the typical shoreline of Shenzhen in China. Results reveal that Shenzhen's beaches experienced erosion up to 12 m over the past 35 years. Here we project a decrease in the mean erosion rate of the beaches, identifying population growth (21.0 %) as the main controlling factor before the mid-century in a range of scenarios. We find that Attention-LSTM multi-model ensemble approach can provide overall improved accuracy and reliability over a wide range of beach erosion compared to scenario prediction model of Attention-LSTM and statistical model of Digital Shoreline Analysis System (DSAS), yielding an average uncertainty of 10.99 compared to 13.29. These insights reveal policies to safeguard beaches because of the rising demand for beaches due to human factors, coupled with decreased impervious surfaces through ecological conservation, lead to mitigation for beach erosion. Accurate forecasts empower policymakers to implement effective coastal management strategies, safeguard resources, and mitigate erosion's adverse effects. Our study offers finely-tuned predictions of coastal erosion, providing crucial insights for future coastal conservation efforts and climate change adaptation along the shoreline, and serving as a foundation for further research aimed at understanding the evolving environmental impacts of beach erosion in Shenzhen.

The comparative advantage of urban goat production.

Urban agriculture significantly contributes to food security. The two primary components of urban agriculture are livestock production and horticulture. The goat, Capra hircus, is one of the commonly raised food animals. Goats can be used to generate income, produce milk, meat, skins, furs (hairs) and manure and provide various sociocultural and ecological services. This study evaluates the significance of urban goat production and recommends ways to lessen the adverse impacts of urban goat production. This report involved an in-depth interview with seven key informants in Adama and Addis Ababa cities. Goats can thrive in limited urban open spaces, scavenge leftovers from homes and open markets and browse on open public land. Goats can be incorporated into urban agriculture, in so doing contributing to a circular economy. Goats can thrive on a limited supply of water and feed and require less care and space. Goat farming is used to mitigate the adverse impact of climate change. Goats are naturally active, which makes them better at avoiding traffic accidents. Goats can be used to control bush encroachment. Goat farming in cities improves land use efficiency and food security. Being friendly animals, goats can be utilized to play with kids, and they can be a basic piece of metropolitan ecotourism. However, goats can harm urban green spaces; therefore, to avoid issues of this kind, goat production must be zoned. Urban goat farming could add a new dimension to urban food security. Extensive pieces of empirical evidence need to be generated to enhance the adoption of urban goat farming.

Temperatures, conflict and forced migration in West Asia and North Africa

The region of West Asia and North Africa has not only been termed a “hotspot” region for the adverse impact of climate change in light of extreme temperature increases. Several countries have also experienced protracted humanitarian crises and civil wars in the last two decades, such as those in Syria, Yemen and Libya. The vulnerability of these populations makes advancing our understanding of how climate change may impact migration patterns in the region a matter of urgency. This study examines whether extreme temperatures influence bilateral forced migration between countries within West Asia and North Africa through their potential to increase armed conflict. The findings suggest that extreme temperatures in two consecutive years, defined as the upper 10% of the country-specific annual mean temperature distribution, cumulatively increase the probability of armed conflict by 42.5% in the following year ( p = 0.07). Armed conflict is strongly associated with an increase in asylum flows, by 45.8 percentage points ( p = 0.00), and there is a weak indication that conflict mediates the relationship between extreme heat and asylum flows. This explorative study is the first to apply a regional displacement perspective to the climate-conflict-migration nexus in West Asia and North Africa. The results underline the importance of taking contextual factors into account in the analysis of environmental migration.

The effect of lightweight geopolymer concrete containing air agent on building envelope performance and internal thermal comfort

Innovative building materials are the primary focus for researchers seeking to reduce energy consumption and advance global sustainability initiatives. This target could accomplished by addressing environmental issues and confronting the adverse impact of climate change. In this regard, this paper used a combined experimental and simulation approach to evaluate the effectiveness of lightweight geopolymer concrete (LWGC) incorporating industrial waste of aluminum powder (AP) and ferrosilicon waste powder (FWP) for reducing the energy consumption in the building envelop. Seven concrete mixes for LWGC were prepared using an air operator. Three mixtures contain 0.1 %, 0.2 %, and 0.3 % AP (FA), and three mixtures contain 0.1 %, 0.2 %, and 0.3 % FWP by weight of fly ash. The workability, unit volume weight, compressive strength, thermal conductivity, and microstructure analysis of the LWGC were examined. In addition, energy simulations were performed to evaluate their ability to reduce energy use in residential buildings. The inclusion of AP and FWP in LWGC resulted in a significant decrease in the density of the material, which amounts to 55 % for AP0.3 and 35 % for FWP0.3. The diameter of the LWGC pore structure increased as the Ca/Si ratio was reduced. The AP and FWP materials reduced energy consumption for building envelope elements such as external walls and roof insulation by 14.5 %, resulting in a 9.2 % overall reduction compared to the traditional concrete mix as a control sample.

Evaluation of the Impact of Climate Change on the Water Balance of the Mixteco River Basin with the SWAT Model

Assessing the impact of climate change is essential for developing water resource management plans, especially in areas facing severe issues regarding ecosystem service degradation. This study assessed the effects of climate change on the hydrological balance using the SWAT (Soil and Water Assessment Tool) hydrological model in the Mixteco River Basin (MRB), Oaxaca, Mexico. Temperature and precipitation were predicted with the projections of global climate models (GCMs) from the Coupled Model Intercomparison Project Phase 6 (CMIP6); the bias was corrected using CMhyd software, and then the best performing GCM was selected for use in the SWAT model. According to the GCM MPI-ESM1-2-LR, precipitation might decrease by between 83.71 mm and 225.83 mm, while temperature might increase by between 2.57 °C and 4.77 °C, causing a greater atmospheric evaporation demand that might modify the hydrological balance of the MRB. Water yield might decrease by 47.40% and 61.01% under the climate scenarios SP245 and SSP585, respectively. Therefore, adaptation and mitigation measures are needed to offset the adverse impact of climate change in the MRB.

This study will help the Policy makers and governments to cope with the adverse impact of climate change.

Representation of Forests in Pragya Nepali Aadhunik Katha: A Critical Inquiry

The portrayal of forests in literature has long captivated readers, evoking a spectrum of emotions including fear, mystery, and freedom, among others. This paper delves into the portrayal of forests in literature, particularly focusing on the narratives collected by the three volumes of Nepal Academy in Pragya Nepali Aadhunik Katha. Considering the adverse impact of climate change on forests, this paper argues that literature plays a crucial role in shaping societal perspectives and behaviors to combat climate crises. It argues for the inclusion of environmental themes, particularly forests, in literary works, advocating for their potential to inspire action and cultivate a sense of community engagement. The representation of forests in literature published by organizations such as Nepal Academy, a government body, could prove crucial in instigating behavioral changes among people and promoting sustainable choices that aid in combating the climate crisis. By analyzing the selected stories from the three volumes of Pragya Aadhunik Nepali Katha, this research explores the extent of agency given to forests as integral components of stories. The analysis will be contextualized within Michaels’ idea of “monoculture,” and other relevant discussions surrounding the climate crisis. The findings aim to highlight the importance of incorporating forests into literary narratives, encouraging an understanding of their significance among readers and policymakers alike.

Future eco-hydrological dynamics: Urbanization and climate change effects in a changing landscape: A case study of Birmingham's river basin

The global challenges of water availability and quality are driven by land use and climate changes, further exacerbated by global warming. Altered Land Use and Land Cover (LULC) due to urbanization, deforestation, and agriculture triggers many environmental issues to eco-hydrological systems, which are already profoundly impacted by shifting climate patterns. The Upper Black Warrior River Basin in Birmingham, Alabama, is a prime example of how converting forests into urban areas impairs water quality and increases surface runoff due to impermeable surfaces. This study delved into the temporal and spatial alterations in eco-hydrologically relevant flows, considering individual and combined climate change scenarios and LULC transformation. The Soil and Water Assessment Tool (SWAT) served as the modeling platform, calibrated (2016–2022) and validated (2011–2015) at a daily time scale. Five distinct scenarios were crafted to portray eco-hydrology's past, present, and future responses (runoff and river nutrients) to climate and LULC variations. The model demonstrated strong performance for discharge and predicted increased runoff in future periods, which is attributed to the anticipated warmer, wetter winters and hotter, drier summers characterized by more intense rainfall events. Notably, the study unveiled the adverse impact of climate change on monthly nitrates leaching into surface runoff, with the lowest levels predicted during May to September coinciding with reduced precipitation. Conversely, human activity positively impacts runoff, especially in FMC, which has a higher deforestation rate (42.8%) and increased runoff compared to VC. The study also emphasized the significant link between flow and nutrient concentration, highlighting the dominant role of nonpoint sources in contributing to these inputs. These findings have significant implications for local stakeholders, necessitating considering the potential consequences of integrated climate change and urbanization on eco-hydrology. Effective management strategies, such as improved land use practices and reduced nutrient leaching, must be implemented to minimize these impacts.

The impact of climate change on credit risk of rural financial institutions: A threshold effect based on agricultural insurance

Climate change affects the stability of the rural financial system. This paper uses the multi-agent model to deduce the impact mechanism of climate change on the credit risk of rural financial institutions, and conducts a series of empirical tests. The results show that: (i) climate change has an adverse impact on the credit risk of rural financial institutions. (ii) agricultural insurance shows a threshold effect in the process of climate change affecting the credit risk of rural financial institutions. (iii) high-level agricultural insurance can mitigate the adverse impact of climate change on the credit risk of rural financial institutions. It reveals that the agricultural insurance is a crucial policy for taking precautions.

Climate Change Exposure and Bankruptcy Risk

AbstractThis research documents that a firm's bankruptcy risk increases with its climate change exposure. This study further investigates the underlying mechanisms and finds that this effect is stronger for firms with lower operating cash flows or tighter financial constraints. Consistent with the agency theory of debt, the evidence suggests that improving the protection of creditor rights can mitigate the adverse impact of climate change. In addition, two distinct sets of quasi‐natural experiments are exploited to establish causality and eliminate alternative explanations. Specifically, the positive effect of climate change exposure on bankruptcy risk is weaker after the 2015 Paris Agreement, which raised public awareness of climate issues, and stronger for firms headquartered in countries that are more severely affected by natural disasters. Cross‐sectional analyses reveal that the main effect is more pronounced among loss firms, firms with higher levels of asset tangibility, cash flow volatility or profit volatility, and firms with worse solvency performance. Overall, the collective evidence indicates that climate change has real consequences for firm financial conditions.

Comprehensive review: Effects of climate change and greenhouse gases emission relevance to environmental stress on horticultural crops and management

Global climate change exerts a significant impact on sustainable horticultural crop production and quality. Rising Global temperatures have compelled the agricultural community to adjust planting and harvesting schedules, often necessitating earlier crop cultivation. Notably, climate change introduces a suite of ominous factors, such as greenhouse gas emissions (CGHs), including elevated temperature, increased carbon dioxide (CO2) concentrations, nitrous oxide (N2O) and methane (CH4) ozone depletion (O3), and deforestation, all of which intensify environmental stresses on crops. Consequently, climate change stands poised to adversely affect crop yields and livestock production. Therefore, the primary objective of the review article is to furnish a comprehensive overview of the multifaceted factors influencing horticulture production, encompassing fruits, vegetables, and plantation crops with a particular emphasis on greenhouse gas emissions and environmental stressors such as high temperature, drought, salinity, and emission of CO2. Additionally, this review will explore the implementation of novel horticultural crop varieties and greenhouse technology that can contribute to mitigating the adverse impact of climate change on agricultural crops.

Climate change and adaptive strategies for agriculture in Panchkhal Municipality

Climate change is a modern global crisis caused by human activities that emit greenhouse gases and alter the Earth's natural systems. It is now an undeniable global burning issue, affecting the complex relationship between the physical landscape, natural resources, and how communities adapt to the effects of climate change. Climate change brings many uncertainties to the livelihoods of farming communities that depend on weather and climate. The purpose of this paper is to examine the climate change and adaptive strategies of the farmers in Panchkhal Municipality using an explanatory mixed-methods research design. Primary data were collected from field observation, questionnaires, and interviews. Secondary data were collected from the Center Bureau of Statistics (CBS) and the Department of Hydrology and Meteorology (DHM). The finding shows the many impacts of climate change, such as hot waves, floods, landslides, droughts, increased diseases in agriculture production, and drying up water resources. Similarly, it shows that traditional adaptive strategies have been changing due to a decline in food crop production over the last two decades. Thus, strong policy efforts need to be prepared to mitigate the adverse impact of climate change on traditional farming methods.

Changes in soil organic carbon stocks of forestlands and grasslands on the Loess Plateau, 1980–2015

Soil organic carbon stocks (SOCS) are critical for both maintaining many ecosystem functions and regulating global climate. To address the serious soil erosion and land degradation problems on the Loess Plateau (LP), the Chinese government launched the famous “Grain for Green Program” (GGP) in 1999. However, how the SOCS change under the impacts of both GGP and climate change remains unclear. Here, we investigated the impacts of climate change and the GGP on SOCS of the top 1 m soil on the LP during 1980–2015, using a data-driven model and a multi-period land use/cover dataset. Our SOCS estimates showed that SOCS of grasslands and forestlands on the LP ranged from approximately 1400 ± 75 to 1700 ± 77 Tg C during 1980–2015. The SOCS of grasslands ranged from approximately 1000 ± 56 to 1200 ± 58 Tg C, which were roughly twice those of forestlands. Our analyses suggested that SOCS of grasslands and forestlands on the LP varied in the years before the GGP was launched in 1999, due to the continued warming and frequent drought. Unexpectedly, the SOCS did not significantly enhance after the GGP was implemented. Compared to 1995, the SOCS of grasslands and forestlands on the LP only increased on average by approximately 3.7% during 2000–2015, due mainly the adverse impact of climate change, as well as the limited effect of vegetation restoration on SOC at the early stage of the vegetation restoration programs. The study highlights the noticeably adverse effects of climate change on SOCS in the LP, providing valuable scientific support for the implementation of large-scale ecological restoration initiatives in the region.

Mitigating the adverse effect of warming on rice canopy and rhizosphere microbial community by nitrogen application: An approach to counteract future climate change for rice

The adverse impact of climate change on crop production continues to increase, necessitating the development of suitable strategies to mitigate these effects and improve food security. Several studies have revealed how global warming negatively impacts the grain-filling stage of rice and that this effect could be mitigated by nitrogen; however, the impact of nitrogen application on rice canopy and rhizosphere microbial communities remains unclear. We conducted a study using an open-field warming system. Results showed that warming influenced rice canopy by decreasing aboveground biomass and harvest index, whereas nitrogen application had positive effect on rice production under warming conditions by increasing the plant nitrogen content, biomass, harvest index and soil fertilities. Moreover, soil ammonium nitrogen (NH4+-N) and nitrate nitrogen (NO3−-N) contents were significantly decreased under warming, which were higher after nitrogen application. Notably, warming and nitrogen fertilizer caused 19 % (P < 0.01) and 7 % (P < 0.05) variations, respectively, in the β diversity of the microbial community, respectively. The impact of warming was significant on NH4+-N-related microorganisms; however, this impact was weakened by nitrogen application for microbes in the rhizosphere. This study demonstrated that enhanced nitrogen fertilizer can alleviate the adverse impact of warming by weakening its effects on rhizosphere microbes, improving soil fertility, promoting rice nitrogen uptake, and increasing the aboveground biomass and harvest index. These findings provide an important theoretical basis for developing practical, responsive cultivation strategies.

Impact of Climate Change on water security and Endorsing importance of Rainwater Harvesting Technology in Nepal

The day-by-day increment in the concentration of greenhouse gases (GHGs) in the atmosphere is widely believed to be a main contributing factor for climate change. It affects widely on diverse sectors such as water resources, agriculture, forestry, human health, biodiversity, and snow cover and aquatic life. Nepal is experiencing the adverse impact of climate change; this includes such as a variability in temperature and precipitation, overbank flooding from snow-fed rivers, and variability in available river and stream water quantity. Climate in the Nepal Himalayas is changing faster than the global average. Moreover, the changes in the high-altitudes have been found more pronounced than in the low-altitudes. Since, there is no definite trend that could be found in the annual precipitation records, clear decreasing trends could be seen in annual number of rainy days during the study period of 1971-2000. The glaciers in the Nepal Himalayas are shrinking rapidly and there will be no glaciers left by 2180. An accelerated glacier melt will cause an increase in water availability at the beginning but ultimately a decrease in water availability after the glaciers disappear. This will widen the gap between water supply and demand. Changing climate may further exacerbate the water stress which already happening in Nepal due to the monsoon dominated climate. Climate change (CC) will also further increase the seasonal imbalance- too much of water during rainy season and too less of it during dry seasons. Rainwater harvesting technology has the potential to provide numerous benefits to communities and individuals, particularly in areas where water resources are scarce or unreliable. From the analysis and through our research work it is found that if we can simply install and construct rainwater harvesting technology in our individual household only. It nearly fulfills about 15-25% of our domestic water demand. As in urban and rural area of Nepal still nearly about 50% of water demand is fulfilled by groundwater source which increase to 60-70% in dry season. The projected physical impacts of climate change on water resources would have substantial socioeconomic impacts and consequences for Nepal. The hydropower potential and agricultural production would be seriously affected by global warming. A reduction in agricultural production would be experienced due to water security and have significant impact on the food security and livelihoods of the subsistence farmers, who make the majority of the Nepal’s population. As the urgent need for climate change mitigation remains crucial, putting all the necessary resources and institutions in place for future adaptation is indispensable. The Inter-governmental Panel on Climate Change (IPCC) has listed rainwater-harvesting as a key strategy for a planned adaptation in the water sector. The policy statements about rainwater harvesting-based climate change adaptation are currently not being effectively coordinated.

A Scenario-Based Spatial Multi-Criteria Decision-Making System for Urban Environment Quality Assessment: Case Study of Tehran

Spatial evaluation of urban environment quality (UEQ) is a key prerequisite in urban planning and development. The main goal of this study is to present a scenario-based spatial multi-criteria decision-making system for evaluating UEQ. Therefore, stakeholder involvement was conducted and eight environmental criteria and six spatial-functional criteria were identified for five districts of Tehran. The weight of the effective criteria was calculated using the analytic hierarchy process (AHP) model. Then, the ordered weighted averaging (OWA) model was used to prepare UEQ maps in different scenarios, including very pessimistic, pessimistic, intermediate, optimistic, and very optimistic. Finally, the spatial distribution of the district population in different classes of UEQ was evaluated. Among the spatial-functional and environmental criteria, the sub-criteria of population density and air pollution, respectively, had the greatest impact on UEQ. In very pessimistic, intermediate, optimistic, and very optimistic scenarios, approximately 76.7, 51.8, 36.4, 23.7, and 9.8 km2 of the studied area had unsuitable UEQ conditions, respectively. In the very pessimistic scenario, about 37,000 and 1,500,000 people lived in areas with suitable and unsuitable UEQ conditions, respectively. In the very optimistic scenario, the population increased to over 917,000 in areas with suitable UEQ and decreased to 336,000 in those with unsuitable UEQ conditions in terms of both environmental and spatial-functional criteria. The research results showed that a high percentage of the population in the study area live under unsuitable UEQ conditions, which indicates the need for attention to improving the current UEQ conditions. The proposed approach is timely to gain a better understanding of the adverse impact of climate change on human well-being in marginal societies and how climate-resilient urban planning can play a significant role.

Sustainable energy and environmental management practices in the recreation and tourism industries in Nsukka metropolis of Enugu State

Sustainable energy and good environmental management practices are potent factors that can be used to achieve clean energy and sustainable economic growth. This is a global problem that needs immediate action and intervention to reduce the adverse impact of climate change to humanity. This study investigated the sustainable energy and environmental management practices in the recreation and tourism industries in Nsukka metropolis of Enugu State. The descriptive research design was adopted for the study. The population of the study consisted of 209 recreation and tourism service providers in Nsukka Metropolis. Instrument for data collection was a structured questionnaire which was validated by three experts from the University of Nigeria, Nsukka. The instrument has a reliability coefficient of 0.81. Frequency and percentages were used to determine level of sustainable energy and environmental management practices, while phi coefficient was used to determine relationship between sustainable energy and environmental management practices. Findings showed that recreation and tourism possess very low level of knowledge of sustainable energy use. They however showed positive attitude towards sustainable energy through the adoption of energy saving devices like energy bulbs, solar PVs etc. There is strong positive relationship between knowledge of sustainable energy and environmental management practices. The researchers recommended that government should improve on its effort to create awareness of sustainable energy use and environmental management practices among the populace if the problem of climate change is to be abated.

Climate change and agriculture in a coastal region: A case study of betel leaf cultivation in Sagar Island, Kakdwip, South 24 Parganas

Agriculture is a function of temperature and precipitation. Any change in these parameters, above and below the threshold value, will affect photosynthesis and transpiration in the crops, leading to an overall negative impact on agriculture, threatening global food security. Underdeveloped and developing worlds are most likely to be affected due to this situation because more than 80% of the population in this area is economically dependent on agriculture. With this background in mind, the present study attempts to delve into the impact of climate change on betel leaf cultivation in the study area because it forms the backbone of the local economy. Low lying coastal areas bear testimony of the primary evidences of climate change. The study area, therefore, is an ideal location to study the impact of climate change as it is situated in the path of frequent extreme weather phenomena. Such areas are particularly vulnerable to climate change in the form of sea level rise in response to increased precipitation resulting out of rise in temperature. The sensitivity of betel leaf to minor fluctuations in climatic parameters and its economic importance in the selected study area justifies the theme of enquiry. The present paper analyses meteorological data on temperature and rainfall along with field observation to investigate the issue. Given the sensitivity of betel leaf to such changes, an adverse impact on its production seems inevitable. However, findings of the present study prove otherwise. Firstly because the rise in temperature is less than 1.5 degree centigrade, which according to IPCC is the threshold value for impact on agriculture. Secondly, the adoption of adaptive strategies like use of fertilizer, soil treatment etc. practiced in the area largely offsets the adverse impact of climate change on crop production. However, the impacts are not entirely escapable.

Climate change and corporate cash holdings: Global evidence

AbstractUsing data from 41 countries, we provide novel empirical evidence that firms’ cash holdings are positively associated with their climate change exposure. This evidence is robust to different model specifications and survives a battery of tests to ease concerns related to spurious correlation and omitted variable bias. Using the release of the Stern Review as an exogenous shock to climate change awareness, we show that this association becomes significantly stronger after the release of the Review and particularly so for firms with higher exposure to regulatory and transition risk dimensions of climate change as well as financially constrained firms. Overall, results fit consistently within the precautionary motive framework and suggest that firms hold more cash to safeguard against the adverse impact of climate change.
