Coastal embayments are dynamic ecosystems facing environmental and anthropogenic pressures, including bivalve aquaculture and climate change. Mesozooplankton, essential for transferring energy from primary producers to higher trophic levels, serve as indicators of habitat changes. Size structure is a critical trait that reflects local community dynamics, trophic interactions, and ecosystem conditions, offering insights into the functioning and resilience of aquatic environments. This study examines the spatio-temporal variation in mesozooplankton size structure across nine bivalve aquaculture embayments in Atlantic and Pacific Canada from 2020 to 2022. Using high-resolution imaging (FlowCam®) to measure individual zooplankton, we assessed the effects of location, tide, sampling day, season, and aquaculture pressure on the size distribution variation among and within bays. Results indicate that bays with similar size distributions tend to have larger mesozooplankton, while those with more variable distributions are dominated by medium-sized individuals. Significant associations between environmental factors and size variation were observed in four of eleven sampling events. Notably, St. Peters Bay, with the highest aquaculture pressure, showed significant variation associated with station location and sampling day. However, the tide effect was significant only in two sampling events. Seasonal analysis revealed that colder months generally exhibited larger median sizes, with some exceptions influenced by local conditions. Despite high levels of aquaculture pressure in some bays, no consistent association between aquaculture pressure and size variation was found, highlighting the influence of local environmental factors. This study underscores the importance of monitoring mesozooplankton size structure as a bioindicator for effective ecosystem management and targeted conservation strategies.

This study evaluates the environmental suitability and water resource impact of photovoltaic (PV) and concentrated solar power (CSP) systems in the desert regions of Northwest China. A Multi-Criteria Decision Analysis (MCDA) approach is employed, integrating seven key indicators that encompass climate, geography, and location perspectives. Methods such as AHP, CRITIC, CVM, IWC, and EWM are integrated into the MCDA system, with sensitivity analysis conducted to ensure the robustness of weight coefficients. Additionally, the study employs the Water Resource Pressure (WRP) index and spatial Gini coefficient to quantify the Water-Energy conflict. The findings indicate that the Tengger and Kumtag Deserts exhibit higher environmental suitability, lower water resource pressure, and favorable spatial equilibrium, making them optimal for PV and CSP development. In contrast, the Ulan Buh, Badain Jaran, and Qaidam Deserts face significant water resource pressures, necessitating careful planning to avoid ecological impacts. This study introduces a comprehensive framework that combines suitability assessments with water resource evaluations at a fine spatial scale of 0.25-degree grids. The proposed “Water-Electricity-Road” network framework addresses water scarcity and infrastructure accessibility, thereby optimizing solar energy utilization in desert regions. These insights offer valuable guidance for sustainable solar energy planning in arid regions globally.

The study area is one of the biggest gorges in southeast Ethiopia formed by the Wabe Shebelle river. The road was constructed to connect Gasera to Indeto. The study aimed to map and gives some mitigation strategies for geohazards along the road corridor in Southeast Ethiopia using a GIS with AHP & FR technique within the 3 km buffer zones along the road corridor. The study included field investigations and inventorying, characterization of geological situations, assessments of the hydrogeological conditions, and identification of slope instability variables. A GIS technique was used to map an LSM with the combination of two models (AHP and FR). The study used eight factors: slope, aspect, lithology, rainfall, altitude, road proximity, river proximity, and land use/cover. The results of the study revealed that LSZ maps performed using FR and AHP were 64.5 % and 69 % and-the inventory shows high and very high LSZ respectively. Rockfalls, debris/earth slides, and rockslides are commonly observed landslides in the area. Based on the analysis lithology (basaltic and limestone formations) showed the highest contributions for landslide in the area. Slope and aspects show the most frequent landslide hazards in >40, 30–40°, and east, and northeast respectively. Generally, the study found that lithology, slope, and aspect were the main factors contributing to slope instability in the study area. The produced landslide susceptibility map is very important for urban planners, agricultural studies, environmentalists, and future landslide hazardous prevention and mitigation strategies.

Mussel farms can introduce disturbances to the diversity of soft bottom benthic macroinvertebrate communities. This study aimed to evaluate the ecological processes and mechanisms underlying responses from communities in two mussel farming areas in Chile, which is the largest exporter in the world. Alpha diversity indices, additive beta partitioning, and the Raup-Crick null model were employed for analysis. Results indicate a significant impact of mussel farming on both alpha and beta diversity, primarily through species replacement processes, and neutral mechanisms of ecological drift and dispersal. Alpha diversity decreased, and beta diversity increased near the farm areas with reduced hypoxic sediments. These results have conservation implications, especially considering that mussel farming in Chile is concentrated in regions with high levels of endemism. Because ecological drift is more pronounced in small communities with low dispersal potential, endemic and rare species are more susceptible to local extinction. A metacommunity and neutral approach should be integrated into future studies and environmental regulations to improve the assessment of the impacts of mussel farming on diversity.

贻贝养殖场会对软底大型无脊椎动物群落的多样性造成干扰。本研究旨在评估世界上最大的贻贝出口国智利的两个贻贝养殖区群落的生态过程和反应机制。研究采用了阿尔法多样性指数、加法贝塔分区和 Raup-Crick 空模型进行分析。结果表明，贻贝养殖主要通过物种替换过程以及生态漂移和扩散的中性机制，对阿尔法和贝塔多样性产生了重大影响。在缺氧沉积物减少的养殖区附近，α多样性减少，β多样性增加。这些结果具有保护意义，特别是考虑到智利的贻贝养殖集中在具有高度特有性的地区。由于生态漂移在扩散潜力低的小型群落中更为明显，因此特有和稀有物种更容易在当地灭绝。在未来的研究和环境法规中应纳入元群落和中性方法，以改进贻贝养殖对多样性影响的评估。

Persistent dilemma of water resource is one of the most challenging environmental issues worldwide. The shortage of water quantity fundamentally restricts the sustainable development of the economy and society, and the deterioration of water quality further aggravates the shortage of water quantity. The water metabolic mechanism depicts how material elements interact and operate during the inflow and outflow of water resources and pollutants in regional water system contexts, so exploring it from the perspective of dual control of quantity and quality provides a new view for identifying efficient management pathways. Thus, the objective of this study is to predict and analyze the metabolic mechanism for regional water system from the perspective of quantity-quality collaborative control. In detail, the prediction of water metabolism network in future scenario is established based on the Grey Model-Biproportional Scaling Method (GM-RAS) and the Input-Output Analysis (IOA). Subsequently, the Ecological Network Analysis (ENA) is applied to execute water metabolism analysis under the water quantity-quality joint control perspective. The proposed framework is applied to water system management of Zhejiang Province, China. The regional water metabolism development trends are illustrated, water quantity-quality pollutants (COD, NH_3-N) metabolism mechanisms are analyzed, and key industrial sectors for future scenario water system management are identified. The results indicated that: (a) in order to achieve joint improvement of water resource conservation and environmental conditions, agriculture (AGR), manufacturing (MAN), gas (GAS) and the other sectors (OSE) are identified the key industrial sectors. (b) Under the current economic development model, the water system network will evolve towards improving the whole efficiency. The comprehensive dynamic analysis of quality-quantity collaborative control will provide a scientific support to guide the dilemma of water resources in an attempt to promoting the healthy development of water system.

水资源的长期困境是全球最具挑战性的环境问题之一。水量的短缺从根本上制约着经济社会的可持续发展，而水质的恶化又进一步加剧了水量的短缺。水代谢机制描述了在区域水系统背景下，水资源和污染物在流入和流出过程中物质要素如何相互作用和运行，因此从水量和水质双重控制的角度对其进行探讨，为确定有效的管理途径提供了新的视角。因此，本研究的目标是从量质协同控制的角度预测和分析区域水系统的代谢机制。具体而言，研究基于灰色模型-双比例缩放法（GM-RAS）和投入产出分析法（IOA）建立了未来情景下的水代谢网络预测。随后，在水量-水质联合控制视角下，应用生态网络分析法（ENA）进行水代谢分析。所提出的框架适用于中国浙江省的水系统管理。分析了区域水新陈代谢的发展趋势、水量-水质污染物（COD、NH3-N）的新陈代谢机理，并确定了未来情景水系统管理的关键工业部门。研究结果表明(a) 为实现水资源保护和环境状况的共同改善，农业（AGR）、制造业（MAN）、天然气（GAS）和其他行业（OSE）被确定为重点工业部门。(b) 在当前的经济发展模式下，水系统网络将朝着提高整体效率的方向发展。质量协同控制的综合动态分析将为指导水资源的两难选择提供科学支持，力图促进水系统的健康发展。

The study employed neutrosophic programming to optimize Canada's efforts toward achieving the Sustainable Development Goals (SDGs) by 2030. It focused on maximizing GDP and employment while minimizing carbon emissions and electricity consumption. The findings indicated substantial progress in GDP and employment, with GDP projections aligning closely with ARIMA forecast values. However, the optimization results for reducing carbon emissions and electricity consumption were less favorable, as both exceeded the 2030 targets, though slightly below ARIMA forecasts. These outcomes underscore the ongoing challenge of balancing economic growth with environmental sustainability. Neutrosophic programming proved effective in managing uncertainties and imprecise data, particularly in addressing complex, sometimes conflicting objectives like those within the SDGs. Future strategies include advancing greener technologies in high-emission sectors, introducing policy measures such as incentives for renewable energy, stricter emissions regulations, subsidies for green technologies, and increasing investment in sustainable technology research and development.

该研究采用了中性编程方法，以优化加拿大为在 2030 年前实现可持续发展目标（SDGs）所做的努力。研究重点是最大限度地提高国内生产总值和就业率，同时最大限度地减少碳排放和电力消耗。研究结果表明，加拿大在国内生产总值和就业方面取得了实质性进展，国内生产总值预测值与 ARIMA 预测值非常接近。然而，减少碳排放和电力消耗的优化结果却不尽如人意，虽然略低于 ARIMA 预测值，但都超过了 2030 年的目标。这些结果凸显了在经济增长与环境可持续性之间保持平衡的持续挑战。事实证明，中性编程在管理不确定性和不精确数据方面非常有效，尤其是在处理像可持续发展目标这样复杂、有时相互冲突的目标时。未来的战略包括在高排放行业推广更环保的技术，引入政策措施，如可再生能源激励措施、更严格的排放法规、绿色技术补贴，以及增加对可持续技术研发的投资。

Water availability and accessibility are the most significant challenges facing developing countries like Jordan, which is ranked as one of the world's worst countries in terms of water resources. In Jordan's isolated desert areas, where underground wells supply water for livestock and human consumption, water pumping systems (WPSs) are essential. Therefore, finding alternative energy sources is necessary to power underground WPSs. However, numerous diesel generator (DG) issues impact the energy supply. This article presents the design and evaluation of a hybrid renewable energy system (HRES) powering a WPS in an isolated desert region (Al-Mudawwara village/Ma'an governorate) with a daily demand of 40.71 kWh, which is economically viable, environmentally friendly, and sustainable. Using the HOMER simulation software, the most efficient scenario is determined considering the average monthly solar radiation, average wind speed of 3.79 kWh/m² and 6.31 m/s, respectively, economic limitations, and the component's technical specifications. The net-present cost (NPC), cost of energy (CoE), and the percentage of renewable energy fraction (REF) and Greenhouse gas emissions (GHGE) are utilized as optimization criteria. The results obtained show that the scenario with minimum initial capital cost (ICC) and total NPC, respectively, was the one with DG/WT/storage batteries (SB) ($US 53,69) and ($US 59,611). The HRES (PV/WT/SBs) is the optimal scenario since it produces power at the lowest CoE ($US 0.241/kWh), leading to reliable energy and eliminating GHGE.

Through an extensive investigation of enforcement practices in the grasslands of X Banner, Inner Mongolia, it posits that “weak enforcement” reflects an inadequate response by enforcers to societal expectations. The study reveals that enforcement capacity and various factors from overlapping domains in the enforcement field influence the enforcement process. The key elements identified as critical influencers include the dual leadership structure of the bureaucratic system, the conflict between local development objectives and law enforcement goals, the ineffective supervision model used by higher authorities, and the diverse interaction modes among different law enforcement targets at the social space level. These factors collectively exert a complex array of forces on the enforcement process, synergistically contributing to weakened enforcement. Understanding the mechanisms shaping “weak enforcement” helps in diagnosing the root causes of enforcement dilemmas, offering theoretical and practical insights for enhancing grassland ecology governance and law enforcement practices.

The aim of this study was to compare energy consumption and damage assessment in different types of greenhouse structures used for vegetable production. The research focused on analyzing energy indicators in the production of greenhouse products, specifically Tunnel and Quonset greenhouse structures growing cucumber, tomato, and eggplant in Shushtar city. Data was collected from greenhouses with both types of structures, as well as from a random field survey of 20 greenhouses in the city. The results showed that energy consumption in Tunnel greenhouses for cucumber, tomato, and eggplant crops was 4.35 × 10⁶, 3.85 × 10⁶ and 3.33 × 10⁶ MJ ha⁻¹ respectively. For Quonset greenhouses, the energy consumption for the same crops was 4.86 × 10⁶, 4.36 × 10⁶ and 3.85 × 10⁶ MJ ha⁻¹, respectively. The energy efficiency for each crop and greenhouse type was also calculated. The study found that Quonset greenhouses had higher energy consumption compared to Tunnel greenhouses, with cucumber crops showing the highest energy consumption. The highest yield was achieved with cucumber crops in Quonset greenhouses, while the lowest yield was seen with eggplant crops in Tunnel greenhouses due to differences in structure dimensions. Environmental effects analysis revealed varying levels of pollution caused by resource usage, with eggplant production in Quonset greenhouses showing the highest pollution levels. Recommendations were made to optimize electricity, diesel fuel, and fertilizer use to reduce energy consumption and environmental impact. The study suggested the adoption of renewable energy sources like solar power to mitigate energy consumption in greenhouse production.

Societal “imbalance” and “injustice” are key concerns during heatwaves that are considered a typical climate change phenomenon. However, our understanding of precise ways to measure and respond to environmental justice needs remains limited. In this study, we develop an equity index to examine environmental justice problems with respect to social resource provisions during heatwave responses. A multi-source data integration approach and a synthetic population algorithm are used to construct a method to calculate environmental equity indices with 100∗100 m spatial resolution. The resultant integrated equity index map offers a comprehensive view of the urgent need for social resource provision during heatwave responses. Our findings reveal that, despite a higher demand for heatwave-related resources in central urban areas, some suburban regions, particularly emerging cross-boundary functional zones, exhibited lower levels of equity due to inadequate social resource supplies. Additionally, we explored the correlation between social media data based heatwave perception maps and environmental equity levels, confirming the potential of using the heatwave perception to validate the equity index. This study not only mapped out priority areas but also set the stage for targeted interventions to enhance resilience and justice in urban planning.
