Food waste infers considerable environmental, social, and economic consequences. While previous research has focused on interventions at the supplier-retailer interface to reduce surplus, this paper explores the reduction potential in applying legal instruments and evaluates the climate benefits of enforcing four different policy measures: 1) Prohibiting Unfair Trading Practices; 2) Advancing Redistribution of Surplus; 3) Enforcing Best Available Technology; and 4) Legally binding reduction targets. Applied to the case study of bread in Sweden, the results clearly show that, through the enforcement of binding regulations or market-based mechanisms, surplus could be reduced by 6–50 %, while also lowering climate impact with up to 18 % compared to the current system. The results illustrate how Sweden can optimize its bread supply chain through regulatory and market-based strategies, with applicability on an international scale. These findings also highlight the potential in combining legislation and economic incentives to optimize the conventional bread supply chain, for reduced waste and improved surplus management. By demonstrating the benefits of enforcing different legislations and policy measures, the results can be used to further develop and enforce targeted policy recommendations and legislations for reduced food waste. While the scenarios explored are specific to the bread supply chain, the insights gained are applicable to other perishable food sectors facing similar waste management challenges.

食物浪费会导致严重的环境、社会和经济后果。虽然以前的研究主要集中在供应商-零售商界面的干预措施以减少盈余，但本文探讨了应用法律工具减少盈余的潜力，并评估了执行四种不同政策措施的气候效益：1)禁止不公平贸易行为；（二）推进剩余再分配。3)执行最佳可用技术；4)具有法律约束力的减排目标。应用于瑞典面包的案例研究，结果清楚地表明，通过执行具有约束力的法规或基于市场的机制，过剩可以减少6 - 50%，同时与现行制度相比，还可以将气候影响降低18%。研究结果说明了瑞典如何通过监管和市场战略优化其面包供应链，并在国际范围内适用。这些发现还强调了将立法和经济激励相结合以优化传统面包供应链、减少浪费和改进剩余管理的潜力。通过展示执行不同立法和政策措施的好处，研究结果可用于进一步制定和执行有针对性的政策建议和立法，以减少食物浪费。虽然所探讨的场景是针对面包供应链的，但所获得的见解适用于面临类似废物管理挑战的其他易腐食品行业。

To slow climatic change, all countries must reduce their greenhouse gas emissions. Under the Paris Agreement, countries can reduce climate-relevant emissions both domestically and abroad to meet their nationally determined contributions (NDCs). Remarked for cost-effectiveness and the ability to shift funds to Developing Countries, so far only few countries use Internationally Transferred Mitigation Outcomes (ITMOs). While previously attributed to preferences for domestic co-benefits, “climate backlash” might have changed the tide.

This paper is the first to study public opinion about greenhouse gas emission reductions abroad to meet NDCs within a country that already engages in it. Switzerland is one of the few countries using ITMOs. A population survey (n = 4915) reveals a pattern of support drastically different from other forms of climate policies, as only 18% are in favor of reducing emissions abroad. This implies that future research should study under which conditions public opinion on ITMOs alters and how perceived effectiveness, fairness, and co-benefits influence public opinion on the use of foreign emission reductions to meet domestic decarbonization goals.

为了减缓气候变化，所有国家都必须减少温室气体排放。根据《巴黎协定》，各国可以在国内外减少与气候相关的排放，以实现国家自主贡献（NDCs）。考虑到成本效益和向发展中国家转移资金的能力，迄今只有少数国家使用国际转移缓解成果。虽然以前归因于对国内共同利益的偏好，但“气候反弹”可能已经改变了潮流。本文首次研究了一个已经参与国家自主贡献的国家内部对国外温室气体减排的舆论。瑞士是少数几个使用itmo的国家之一。一项人口调查（n = 4915）揭示了一种与其他形式的气候政策截然不同的支持模式，只有18%的人赞成减少国外的排放。这意味着，未来的研究应该研究在哪些条件下公众对itmo的看法会发生变化，以及感知的有效性、公平性和协同效益如何影响公众对利用外国减排来实现国内脱碳目标的看法。

Can specific ginger genotypes thrive under organic farming (OF) in the acidic Inceptisols of Eastern Himalayas Region (EHR)? This study identifies HP 05/15 as the top performer in yield, quality, and soil health improvement. Over two years (2019–20 and 2020–21), field experiment was conducted involved ten different ginger genotypes with three replications. Results revealed that the lowest incidence of bacterial wilt disease (18.10 %) and maximum fresh rhizome yield (15.50 Mg ha⁻¹) was found at HP 05/15. Meanwhile, significantly higher dry recovery (22.30 %) and crude fiber content (6.89 %) was recorded at Bhaise, followed by HP 05/15. At Bhaise, genotype HP 05/15 was noticed significantly higher (47.30 %) essential oil content and oleoresin (+43.20 % more) content followed by V0.5/2. Similarly, genotype HP 05/15 was registered the significant improvement of production efficiency (41.10 %) and profitability (43.30 %) as comparison to the Bhaise. In case of soil health improvement, genotype HP 05/15 cultivated plot was recorded ∼6.40 % reduced bulk density (pb), increased ∼13.40 % total water stable aggregates (TWSA), ∼6.35 % soil organic carbon (SOC), ∼12.80 % macronutrients, ∼13.50 % micronutrients and ∼ 14.90 % biological activity.

Overall, genotype HP 05/15 recommended for organic farming (OF) cultivation due to its high yield, disease resistance, essential oil content, profitability, and positive effects on soil health improvement, making it ideal for sustainable cultivation in the Eastern Himalayas Region .

在东喜马拉雅地区（EHR）酸性土壤中有机耕作（OF）下，特定的生姜基因型能否茁壮成长？本研究确定HP 05/15在产量、质量和土壤健康改善方面表现最佳。在2019 - 2020年和2020-21年的2年时间里，对10个不同生姜基因型进行了3个重复的田间试验。结果表明，HP 05/15的青枯病发病率最低（18.10%），鲜根茎产量最高（15.50 Mg ha−1）。同时，Bhaise的干回收率为22.30%，粗纤维含量为6.89%，HP 05/15次之。Bhaise品种中，HP 05/15基因型的挥发油含量和油树脂含量分别显著高于47.30%和43.20%，其次是V0.5/2基因型。同样，与百色相比，基因型HP 05/15的生产效率（41.10%）和盈利能力（43.30%）显著提高。在改善土壤健康的情况下，基因型HP 05/15栽培地块的容重（pb）降低了~ 6.40%，总水稳定团聚体（TWSA）增加了~ 13.40%，土壤有机碳（SOC）增加了~ 6.35%，宏量营养素增加了~ 12.80%，微量营养素增加了~ 13.50%，生物活性增加了~ 14.90%。总体而言，HP 05/15基因型因其高产、抗病、挥发油含量高、盈利能力强以及对土壤健康改善的积极作用，推荐用于有机农业（OF）种植，是东喜马拉雅地区可持续种植的理想选择。

Carbon storage in subalpine meadows is an important component of ecosystem services and sustainability. However, little is known regarding the carbon stocks of major herbaceous vegetation types in the subalpine meadow ecosystems of subtropical South China. Field surveys, remote sensing, and carbon stock measurements were used to quantify the total ecosystem carbon stock (TECS) of Belamcanda chinensis (BC), Phragmites australis (PA), Ligularia sibirica (LS), Pteridium aquilinum var. latiusculum (PL), BC + LS, and BC + LS + PL communities in the Wulipo Nature Reserve, Chongqing. The TECS included the total above-ground carbon stocks, the below-ground root (as deep as 30 cm), and the entire soil profile (as deep as 1 m). The TECS significantly increased with plant community distribution area and carbon density. The BC community had the highest above- and below-ground vegetation carbon densities of 323.16 g m⁻² and 482.51 g m⁻², respectively. With the exception of PA, the root carbon densities of all other meadow vegetation species exceeded their above-ground carbon densities. Soil carbon stock in the 0–30 cm portion of the profile accounted for 45–56 % and gradually decreased in the remaining two layers. Soil carbon stocks constituted more than 98 % of the TECS across all plant communities. Thus, plant community distribution patterns formed through plant competition and mutualism significantly affected the carbon stocks of regional ecosystems. Large carbon stocks, coupled with other ecosystem services, suggest value in the conservation and restoration of the subalpine meadow zone through climate change mitigation strategies.

亚高山草甸碳储量是生态系统服务和可持续性的重要组成部分。然而，对华南亚热带亚高山草甸生态系统中主要草本植被类型的碳储量了解甚少。采用野外调查、遥感和碳储量测量等方法，对重庆五里坡自然保护区白桦（belamcananda chinensis， BC）、芦苇（Phragmites australis， PA）、西伯利亚柳枝（Ligularia sibirica， LS）、凤尾蕨（Pteridium aquilinum var. latiusculum， PL）、BC + LS和BC + LS + PL群落的生态系统总碳储量（TECS）进行了定量分析。TECS包括地上总碳储量、地下根系（深30 cm）和全土壤剖面（深1 m），随着植物群落分布面积和碳密度的增加，TECS显著增加。BC群落地上、地下植被碳密度最高，分别为323.16 g m−2和482.51 g m−2。除PA外，其他草甸植被的根系碳密度均大于地上碳密度。0 ~ 30 cm土壤碳储量占45 ~ 56%，其余两层土壤碳储量逐渐减少。在所有植物群落中，土壤碳储量占TECS的98%以上。因此，通过植物竞争和共生形成的植物群落分布格局对区域生态系统的碳储量有显著影响。大量的碳储量，加上其他生态系统服务，表明通过减缓气候变化战略保护和恢复亚高山草甸带具有价值。

India faces environmental issues due to large-scale seasonal in situ burning of crop residues, leading to air pollution and nutrient loss. Biochar application can increase soil carbon content, moisture, and nutrient content while reducing air pollution. India produces 156 Mt. of annual in situ surplus crop residues from ten major crops, with the highest potential for rice residue biomass in Sangrur, Punjab. Biochar could reduce greenhouse gas emissions by 405 Tg annually and its application to soil could sequester 7.5 Tg of carbon. However, competition between biochar and other crop residue management technologies requires a life cycle assessment for sustainable management.

由于大规模季节性就地焚烧作物秸秆，导致空气污染和养分流失，印度面临着环境问题。应用生物炭可以增加土壤的碳含量、水分和养分含量，同时减少空气污染。印度每年从十种主要作物中产生156mt的就地剩余作物残茬，旁遮普的桑格鲁的水稻残茬生物量潜力最大。生物炭每年可减少温室气体排放405 Tg，其在土壤中的应用可固碳7.5 Tg。然而，生物炭和其他作物秸秆管理技术之间的竞争需要对可持续管理进行生命周期评估。

This research explores how epistemological dissonance shapes agrarian sustainabilities in Mbeya, Tanzania. Through a case study of smallholder farmers navigating both market-driven and eco-cultural paradigms of sustainability, the research explores how plural epistemologies shape local sensemaking and agricultural decision-making. It demonstrates how farmers reconcile divergent sustainability logics, those rooted in market interpretations of sustainability with those rooted in relational ethics, ecological stewardship, and cultural continuity within agrarian landscapes. Employing hybrid strategies, farmers compartmentalize production, input intensive, market-targeting monocultures co-exist alongside primarily subsistence agroecological systems. These spatial divisions mirror deeper ontological tensions, as farmers articulate pride in market breakthroughs while expressing anxiety about environmental degradation, cultural erosion, and the loss of intergenerational practices. Building on plural sustainabilities literature and epistemologies of the South theories, the paper adds to scholarship reinterpreting sustainability not as a universal, singular paradigm, but a contested, contextually negotiated process. The case of Mbeya illustrates how epistemological dissonance becomes embodied through emotional and cognitive labor, and how hybrid sensemaking enables farmers to navigate conflicting knowledge systems. Rather than viewing hybridity as incoherence, the paper interprets these strategies as acts of situated resilience, adaptation, and resistance. The analysis contributes to political ecology and sustainability studies by foregrounding the ontological multiplicity at play in agrarian transitions and calls for institutional recognition of knowledge pluralism. Ultimately, the paper proposes a shift toward pluriversal sustainability frameworks that integrate both empirical and relational epistemologies, acknowledging that sustainable futures are as much about values and worldviews as they are about technologies and yields.

本研究探讨了坦桑尼亚姆贝亚的认识论失调如何影响农业的可持续性。通过对小农在市场驱动和生态文化两种可持续发展模式下的案例研究，本研究探讨了多元认识论如何影响当地的意义制定和农业决策。它展示了农民如何调和不同的可持续性逻辑，这些逻辑植根于市场对可持续性的解释，而植根于关系伦理、生态管理和农业景观中的文化连续性。采用杂交策略，农民划分生产，投入集约化，以市场为目标的单一栽培与主要自给农业生态系统共存。这些空间划分反映了更深层次的本体论紧张，因为农民在表达对市场突破的自豪感的同时，也表达了对环境退化、文化侵蚀和代际实践丧失的焦虑。在多元可持续发展文献和南方理论认识论的基础上，本文增加了将可持续发展重新解释为一个有争议的、上下文协商的过程，而不是一个普遍的、单一的范式的学术研究。Mbeya的案例说明了认识论上的失调是如何通过情感和认知劳动体现出来的，以及混合意义制造如何使农民能够驾驭相互冲突的知识体系。本文将这些策略解释为定位弹性、适应和抵抗的行为，而不是将杂交视为不连贯。该分析通过强调在农业转型中发挥作用的本体论多样性，并呼吁对知识多元化的制度承认，有助于政治生态学和可持续性研究。最后，本文提出了向多元可持续发展框架的转变，该框架整合了经验和关系认识论，承认可持续发展的未来与价值和世界观一样重要，也与技术和产量有关。

Serious games play a crucial role in educating and engaging the public on environmental management issues, such as climate change. These games also generate valuable data that can be used in understanding players' climate change decisions. However, there is a notable gap in the literature on serious game analytics to address the significance of scrutinising the usefulness of utilising gameplay data to explore player behaviours. This paper explores this gap through descriptive and quantitative analysis of gameplay data from ‘The Township Flooding Challenge’ in Aotearoa New Zealand to obtain data insights and data gaps in understanding players' behaviours and decisions on climate change adaptation. The findings suggest that gameplay data can offer insights into players' decisions on climate change adaptations amid uncertainty, but also highlights data gaps such as unclear definitions and incomplete data. Leveraging gameplay data can aid in data collection, decision-making modelling, and improving serious game design.

严肃游戏在教育和吸引公众关注环境管理问题（如气候变化）方面发挥着至关重要的作用。这些游戏还产生了有价值的数据，可以用来理解玩家的气候变化决策。然而，关于严肃游戏分析的文献中却存在着一个显著的缺口，即在审视利用游戏玩法数据去探索玩家行为的有用性的重要性。本文通过对新西兰Aotearoa“The Township flood Challenge”游戏玩法数据的描述性和定量分析来探索这一差距，以获得数据见解和数据差距，从而理解玩家在气候变化适应方面的行为和决策。研究结果表明，游戏玩法数据可以为玩家在不确定的情况下适应气候变化的决定提供见解，但也突出了数据差距，如定义不清和数据不完整。利用游戏玩法数据有助于数据收集、决策建模和改进严肃的游戏设计。

This study optimized the co-pyrolysis of oil palm empty fruit bunch (EFB) and rubber wood sawdust (RWS) to enhance biochar and liquid oil yields, with non-condensable gas (NCG) as a by-product. Experiments were conducted in a fixed-bed reactor, varying key process parameters, including pyrolysis temperature (750–850 °C), biomass particle size (0.3–5 mm), and EFB: RWS ratio (0:100–100:0). Response surface methodology (RSM) with a Box-Behnken design (BBD) was employed to analyze parameter interactions and optimize product distribution systematically. Statistical validation confirmed the model's reliability, with prediction errors below 10 %. The optimal biochar yield (33.73 wt%) was achieved at 782.25 °C, a particle size of 2.94 mm, and an EFB: RWS ratio of 6:94. In comparison, the highest liquid oil yield (28.46 wt%) was obtained at 850 °C, with a biomass size of 3.00 mm and an EFB: RWS ratio of 100:0. Co-pyrolysis offers flexibility to adjust product yields based on energy needs. Simulations proved the scalable design and economic analysis confirmed its financial viability with a payback period of just 5.8 years. The environmental evaluation was also conducted through the Life Cycle Assessment (LCA). The LCA revealed that the pyrolysis process had the highest impact on global warming potential (GWP), contributing 61.15 %, followed by product utilization (estimated at 20 %), feedstock production (11.67 %), transportation (2.18 %), and end-of-life processes. This study shows the potential of using local biomass in Southern Thailand for sustainable energy. These findings pave the way for scaling up industrial pyrolysis, enhancing energy security, and waste valorization.

本研究优化了油棕空果束（EFB）和橡胶木锯末（RWS）共热解，以提高生物炭和液体油的产量，副产物为不凝性气体（NCG）。实验在固定床反应器中进行，改变关键工艺参数，包括热解温度（750-850℃）、生物质粒度（0.3-5 mm）和EFB: RWS比（0:100-100:0）。采用Box-Behnken设计（BBD）响应面法（RSM）系统分析各参数的交互作用，优化产品分布。统计验证证实了模型的可靠性，预测误差在10%以下。在782.25℃、粒度2.94 mm、EFB: RWS比为6:94的条件下，获得了最佳的生物炭产率（33.73 wt%）。相比之下，在850°C，生物质尺寸为3.00 mm， EFB: RWS比为100:0时，获得了最高的液体油收率（28.46 wt%）。共热解提供了根据能源需求调整产品产量的灵活性。模拟证明了可扩展设计和经济分析证实了其财务可行性，投资回收期仅为5.8年。环境评价也通过生命周期评价（LCA）进行。LCA分析显示，热解过程对全球变暖潜势（GWP）的影响最大，占61.15%，其次是产品利用（估计占20%）、原料生产（11.67%）、运输（2.18%）和生命周期结束过程。这项研究显示了在泰国南部利用当地生物质作为可持续能源的潜力。这些发现为扩大工业热解、加强能源安全和废物增值铺平了道路。

The impacts of climate change on livelihoods and livestock systems in East Africa are significant. Efforts to bolster resilience will require a concerted focus on social equity to foster transformative adaptation. We integrate a feminist lens in a positive deviance approach to better understand gender relations in dairy producing communities in Kenya. We make theoretical and methodological contributions and suggest practical application to support locally led scaling approaches. Data was collected through 20 sex disaggregated focus group discussions (FGDs) and 10 key informant interviews (KII) with a total of 199 research participants. We focus on women's and men's participation in decision-making to assess gendered agency and labor in households, dairy specific activities, and the uptake of climate innovations. Evaluating these relations provides a better understanding of equity in dairy producing households who are at the forefront of climate adaptation. Women's and men's practices vary, and, through a positive deviance inquiry, we find the common patterns in those practices to characterize the referent group using thematic analyses. Our empirical findings demonstrate that referent group norms, relations and practices are, by and large, inequitable in agency and labor in dairy households underpinned by social norms. Positive deviant practices occur at differential rates in diverse geographies. We extended the concept of positive deviance to a relevant and urgent development agenda, transformative adaptation, that, to support resilience, must address root causes of vulnerability. We advocate for increased efforts to utilize positive deviance in future climate adaptation studies to inform practical and locally led strategies.

气候变化对东非生计和牲畜系统的影响是巨大的。加强复原力的努力需要协调一致地关注社会公平，以促进变革性适应。我们将女权主义视角与积极偏差方法相结合，以更好地理解肯尼亚乳制品生产社区的性别关系。我们在理论和方法上做出了贡献，并建议实际应用以支持本地主导的扩展方法。通过20次按性别分类的焦点小组讨论（fgd）和10次关键信息提供者访谈（KII）收集数据，共有199名研究参与者。我们关注女性和男性参与决策的情况，以评估家庭中的性别代理和劳动力、乳制品特定活动以及气候创新的采用情况。评估这些关系有助于更好地了解处于气候适应前沿的乳制品生产家庭的公平情况。女性和男性的实践各不相同，并且，通过积极的偏差调查，我们发现这些实践中的共同模式，使用主题分析来表征所指群体。我们的实证研究结果表明，在社会规范的支撑下，奶牛家庭的代理和劳动中，参照群体规范、关系和实践总体上是不公平的。积极的越轨行为在不同地区以不同的比率发生。我们将积极偏差的概念扩展到相关和紧迫的发展议程，即变革性适应，为了支持复原力，必须解决脆弱性的根源。我们主张在未来的气候适应研究中加大力度利用积极偏差，为切实可行的地方主导战略提供信息。

Urbanization, as a component of land use and land cover (LULC) changes, significantly affects land surface temperature (LST), intensifying the Urban Heat Island (UHI) effect. Therefore, understanding the impact of LULC change on LST is critical for addressing urban heat and advancing sustainable development. In this review, our objective was to evaluate how urbanization-driven LULC changes influence LST patterns across diverse climatic zones, including temperate, tropical, arid/semi-arid, and polar regions. Simultaneously, we assessed the effectiveness of mitigation strategies such as green infrastructure and urban planning interventions. We analyzed more than 73 peer-reviewed studies published between 2004 and 2024.

Our findings reveal that India is the most frequently studied country, followed by China and the United States. Most studies relied on Landsat imagery, while MODIS was more commonly used in polar regions. Research output has increased since 2015, coinciding with advances in satellite platforms and analytical tools. Regionally, semi-arid/arid zones, as well as tropical zones, exhibited the most substantial LST increases, linked to vegetation loss and impervious surface expansion. Among mitigation approaches, urban greening emerged as the most effective and widely applicable strategy. In addition, water bodies, high albedo materials, and optimized urban geometry are also effective in reducing LST.

Overall, our results demonstrate that satellite data selection is strongly affected by regional climate, emphasizing the need for context-specific approaches to monitoring and mitigating urban heat. By integrating regional analyses with mitigation and adaptation strategies, this study provides valuable insights for sustainable urban planning and global efforts to reduce the UHI effect.

城市化作为土地利用和土地覆盖变化的一个组成部分，显著影响地表温度，加剧城市热岛效应。因此，了解土地利用温度变化对地表温度的影响对于解决城市热问题和促进可持续发展至关重要。在这篇综述中，我们的目标是评估城市化驱动的LULC变化如何影响不同气气带的地表温度模式，包括温带、热带、干旱/半干旱和极地地区。同时，我们评估了诸如绿色基础设施和城市规划干预措施等缓解战略的有效性。我们分析了2004年至2024年间发表的73多项同行评议研究。我们的研究结果显示，印度是最常被研究的国家，其次是中国和美国。大多数研究依赖于陆地卫星图像，而MODIS更常用于极地地区。自2015年以来，随着卫星平台和分析工具的进步，研究成果有所增加。从区域上看，半干旱/干旱区以及热带地区地表温度增幅最大，这与植被损失和不透水地表扩张有关。在各种缓解方法中，城市绿化成为最有效和最广泛适用的战略。此外，水体、高反照率材料和优化的城市几何形状也能有效降低地表温度。总体而言，我们的研究结果表明，卫星数据的选择受到区域气候的强烈影响，强调需要针对具体情况的方法来监测和减轻城市热量。通过将区域分析与缓解和适应战略相结合，本研究为可持续城市规划和减少热岛效应的全球努力提供了有价值的见解。
