Waste management is the first priority for many countries, so the focus of this research is on using waste materials in concrete as fillers and substituting concrete ingredients such as crumb rubber (CR) for fine aggregates. The utilization of waste rubber in concrete has gained attention recently, but CR substitution results in a reduction in mechanical and durability properties due to weak bonding and lower stiffness of CR. To overcome this issue, the addition of strength-increasing waste materials as cement substitutes is investigated along with CR (5%, 10%, and 15%) as fine aggregates and tested for the mechanical and durability behavior of concrete. Constant 10% waste glass powder (WGP) and 10% silica fume (SF) were substituted with cement in separate mixes. The main goal of this study is to investigate the suitable proportion of the materials from SF and WGP for enhancing rubberized concrete’s properties and to evaluate waste materials’ uses considering various parameters. The concrete is compared for both materials used as well as with control concrete and CR concrete for properties such as workability, compressive strength, tensile strength, density, ultrasonic pulse velocity, and dynamic modulus of elasticity. The reduction in compressive strength, tensile strength, workability, density, ultrasonic pulse velocity, and dynamic modulus of elasticity was observed due to the incorporation of CR, but also an increase in these properties with the incorporation of silica fumes (SF) and waste glass powder (WGP) as cement. It was observed that SF enhanced the properties of rubberized concrete better as compared to WGP. The 10% SF with 5% CR enhanced the compressive strength of rubberized concrete without SF by 11%. Similarly, 10% of WGP with 5% of CR enhanced the compressive strength of rubberized concrete by 6%.

Multiple uses of water aquaculture-integrated agriculture systems (AIAS) are inevitable to produce more food per drop of water to address water shortage, food insecurity, and climate change. This survey intends to outline the multiple-use water in pond-based AIAS in light of legal regulations and water salinity. Scenarios for pond-based AIA and their impact on the environment were presented and discussed. Pond-based AIA has been demonstrated to have many social, economic, and environmental benefits. Moreover, international and national experiences and attempts for genuine applications were exhibited. Throughout, pond-based AIA farming practices are seen as a proficient utilization of water that aids food sustainability. It was concluded that pond-based AIA could aid in increasing productivity, income for food producers and soil fertility, ecosystem maintenance, and adaptation to environmental change. AIAS helps adapt to and mitigate climate change by reducing waste and greenhouse gas emissions, reducing pressure on water resources, and recycling nutrients. Finally, developing and promoting the expansion of rotation of wheat-fish and pond-based AIA in the desert and encouraging global collaboration for information and knowledge transfer among different countries were discussed.

The widespread usage of granite in the building sector motivated us to conduct this research and examine the material’s sustainability in terms of the investigated characteristics. The purpose of this paper is to discuss the statistical analysis results for the mineralogical impact on radiological hazards indices, such as the equivalent of radium, absorbed gamma dose rate, annual effective dose, internal and external hazard indices, as well as the gamma-ray index, that were calculated to estimate the environmental risks associated with these granites used as building materials, to protect the public from excessive radioactivity exposure. We focused primarily on statistical significance at a 95% confidence level. We employed a non-parametric test (Kruskal–Wallis Test) rather than a one-way ANOVA, to determine the statistical significance of the samples due to the lack of homogeneity or normality among them. To assess the difference between the samples, we used the Mann–Whitney Test on each pair of samples. Additionally, Pearson correlation coefficients for all the mineralogical results are computed. The presence of K-rich minerals (Kefeldspars, biotite) and accessories such as uranophane, uranothorite, allanite, xenotime, fergusonite, aeschynite, zircon, cassiterite, apatite, and sphene, which are mostly found in granitic rocks, determines the level of natural radioactivity of the investigated granites. Most of the rock samples analyzed have indicators of radioactive dangers that are within the acceptable level range, indicating that they are suitable for use as building materials. On the other hand, some samples have environmental criteria that are higher than international standards, indicating that they are unsuitable for use as construction materials.

Consumers are increasingly concerned about the way their food is produced. This is particularly relevant in the case of meat, due to the impacts that its production methods can have on greenhouse gas emissions and its role in climate change. In relation to this issue, the purpose of our research is to obtain more information on the consumer decision-making process for beef, in order to determine the relative importance of sustainability claims and traditional attributes, and identify consumer profiles with similar perceptions and intentions. A choice experiment was used to assess the influence of these attributes on consumers’ purchasing decisions. The results reveal that the best purchase choice for the consumer would be organic beef, produced in Spain, with an animal welfare label and eco-labelled. Later on, a cluster analysis was carried out using consumer beliefs and attitudes towards meat consumption as inputs, together with purchasing behaviour variables. A solution was obtained with three well-defined consumer segments showing different preference patterns: Cluster 1 (Male millennials indifferent towards environment or sustainability), Cluster 2 (Sustainability-concerned mature women) and Cluster 3 (Middle-aged meat eaters with established families). The results of this study are relevant to develop more appropriate strategies that may be adapted to the behaviour and expectations of eco-friendly food consumers.

Sweet marjoram (Majorana hortensis) is an important aromatic herbal plant that has long been used and well managed in the traditional and general medical, pharmaceutical, food, cosmetic, and perfume industries. Thus, the increase in its productivity appears to be of great value since there is a large number of bioactive secondary metabolites as well as an increase in the demand in domestic or foreign markets. The purpose of this study is the possibility of promoting the sustainable development of marjoram in the framework of organic farming through gamma irradiation, chitosan and yeast. Field experiments were conducted in a factorial split-plot design with three iterations over two consecutive seasons (2019 and 2020). The main plot is an abiotic elicitor (15 Gy gamma irradiation), two biotic elicitors 500 ppm chitosan, 0.5% yeast, and a non-elicitor (as control), while in the sub-main plot, there were two organic fertilizers, water extract of moringa 20 g/m2 dry leaves, 20 g/m2 fulvic acid, and 20 g/m2 (NPK); the latter is a traditional agrochemical. Statistical analysis of all characteristics of production and quality of biomass and biologically active secondary metabolites revealed that the use of organic fertilizers helped in increasing the yield of marjoram, both qualitatively and quantitatively, and significantly outperformed the chemical fertilizer. The experiment enhances the comprehensive and integrated development of marjoram under organic cultivation and achieves a promising alternative to traditional cultivation without the use of microbicides and/or agrochemical pesticides.

Abstract Throughout the world, biodiversity and nature's contributions to people are under threat, with clear changes evident. Biodiversity and ecosystem services have particular value in Africa– yet they are negatively impacted by a range of drivers, including land use and climate change. In this communication, we show evidence of changing biodiversity and ecosystem services in Africa, as well as the current most significant drivers of change. We then consider five plausible futures for the African continent, each underlain by differing assumptions. In three out of the five futures under consideration, negative impacts on biodiversity and ecosystem services are likely to persist. Those two plausible futures prioritizing environment and sustainability, however, are shown as the most likely paths to achieving long term development objectives without compromising the continent's biodiversity and ecosystem services. Such a finding shows clearly that achievement of such objectives cannot be separated from full recognition of the value of such services.

One Health est de plus en plus reconnu comme une approche optimale pour faire face au risque mondial de menaces pour la santé provenant de l'interface humaine, animale et écosystémique, et à leur impact. Le Qatar a mis en œuvre avec succès l'approche One Health pour l'enquête et la surveillance des maladies zoonotiques telles que le MERS-CoV et d'autres menaces pour la santé. Cependant, les lacunes actuelles au niveau des institutions et des politiques entravent le maintien de One Health. Dans ce document, nous avons évalué le potentiel de mise en œuvre du cadre One Health pour renforcer et soutenir les capacités One Health au Qatar pour 2022-2027. Pour mettre en œuvre le cadre One Health dans le pays, le rapport d'évaluation externe conjointe (JEE) du Qatar, les enseignements tirés des expériences One Health sur les maladies zoonotiques, à transmission vectorielle et d'origine alimentaire ont été utilisés pour présenter un aperçu de la coordination multisectorielle. En outre, les capacités techniques de One Health et les facteurs nécessaires à son opérationnalisation dans le pays ont également été évalués lors d'une série de réunions et d'ateliers tenus au ministère de la Santé publique en mars 2022. L'infrastructure et les ressources actuelles en matière de soins de santé se sont avérées propices à une gestion et à une réponse efficaces aux menaces communes pour la santé, comme en témoigne le MERS-CoV, bien qu'elles soient davantage basées sur les événements. Quoi qu'il en soit, la nécessité d'un développement plus durable des capacités a été unanimement soulignée. Le consensus entre toutes les parties prenantes et partenaires concernés était qu'il était nécessaire d'améliorer les canaux de communication, les politiques et les protocoles pour le partage des données, et la nécessité d'investir plus de ressources pour une meilleure durabilité. Le cadre proposé devrait renforcer et faciliter la coordination multilatérale, améliorer les capacités et le réseau des laboratoires, améliorer la surveillance active et la réponse, la communication des risques, l'engagement communautaire, maximiser la recherche appliquée et constituer une main-d' œuvre technique One Health. Cela permettrait de faire progresser et de soutenir les activités One Health pour prévenir et contrôler les menaces pour la santé partagées entre l'interface homme-animal-écosystème. One Health se reconoce cada vez más como un enfoque óptimo para abordar el riesgo global de las amenazas para la salud que se originan en la interfaz humana, animal y del ecosistema, y su impacto. Qatar ha practicado con éxito el enfoque One Health para la investigación y vigilancia de enfermedades zoonóticas como el MERS-CoV y otras amenazas para la salud. Sin embargo, las brechas actuales a nivel institucional y de políticas dificultan el sostenimiento de One Health. En este documento, hemos evaluado el potencial de implementación de One Health Framework para reforzar y mantener las capacidades de One Health en Qatar para 2022-2027. Para implementar One Health Framework en el país, el informe de Evaluación Externa Conjunta de Qatar (JEE), se utilizaron las lecciones aprendidas durante las experiencias de One Health sobre enfermedades zoonóticas, transmitidas por vectores y transmitidas por alimentos para presentar un esquema para la coordinación multisectorial. Además, las capacidades técnicas de One Health y los factores que se requieren para ponerla en práctica en el país también se evaluaron en una serie de reuniones y talleres celebrados en el Ministerio de Salud Pública en marzo de 2022. Se encontró que la infraestructura y los recursos actuales de atención médica son propicios para una gestión y respuesta efectivas a las amenazas de salud compartidas, como es evidente durante el MERS-CoV, a pesar de estar más basados en eventos. En cualquier caso, se hizo hincapié unánimemente en la necesidad de un desarrollo de capacidades más sostenible. El consenso entre todas las partes interesadas y los socios relevantes fue que existe la necesidad de mejores canales de comunicación, políticas y protocolos para el intercambio de datos, y la necesidad de invertir más recursos para una mejor sostenibilidad. Se espera que el marco propuesto fortalezca y facilite la coordinación multilateral, mejore la capacidad y la red de laboratorios, mejore la vigilancia activa y la respuesta, la comunicación de riesgos, la participación comunitaria, maximice la investigación aplicada y desarrolle la fuerza de trabajo técnica de One Health. Esto permitiría avanzar y mantener las actividades de One Health para prevenir y controlar las amenazas a la salud compartidas entre la interfaz humanos-animales-ecosistema. One Health is increasingly recognized as an optimal approach to address the global risk of health threats originating at the human, animal, and ecosystem interface, and their impact. Qatar has successfully practiced One Health approach for investigation and surveillance of zoonotic diseases such as MERS-CoV, and other health threats. However, the current gaps at institution and policy level hinder the sustainment of One Health. In this paper, we have assessed the potential for implementation of One Health Framework to reinforce and sustain One Health capacities in Qatar for 2022-2027. To implement One Health Framework in the country, Qatar Joint External Evaluation (JEE) report, lessons learnt during One Health experiences on zoonotic, vector-borne, and food borne diseases were used to present an outline for multisectoral coordination. In addition, technical capacities of One Health and factors that are required to operationalize it in the country were also assessed in series of meetings and workshops held at Ministry of Public Health on March 2022. Present health care infrastructure and resources were found to be conducive for effective management and response to shared health threats as evident during MERS-CoV, despite being more event based. Regardless, the need for more sustainable capacity development was unanimously emphasized. The consensus between all relevant stakeholders and partners was that there is a need for better communication channels, policies and protocols for data sharing, and the need to invest more resources for better sustainability. The proposed framework is expected to strengthen and facilitate multilateral coordination, enhanced laboratory capacity and network, improve active surveillance and response, risk communication, community engagement, maximize applied research, and build One Health technical work force. This would enable advancement and sustainment of One Health activities to prevent and control health threats shared between humans-animals-ecosystem interface. يتزايد الاعتراف بـ One Health كنهج أمثل لمعالجة المخاطر العالمية للتهديدات الصحية الناشئة عن التفاعل بين الإنسان والحيوان والنظام الإيكولوجي وتأثيرها. نجحت قطر في تطبيق نهج "صحة واحدة" للتحقيق في الأمراض الحيوانية المصدر ومراقبتها مثل فيروس كورونا المسبب لمتلازمة الشرق الأوسط التنفسية (MERS - CoV) والتهديدات الصحية الأخرى. ومع ذلك، فإن الفجوات الحالية على مستوى المؤسسات والسياسات تعوق استدامة One Health. في هذه الورقة، قمنا بتقييم إمكانات تنفيذ إطار عمل الصحة الواحدة لتعزيز واستدامة قدرات الصحة الواحدة في قطر للفترة 2022-2027. لتنفيذ إطار عمل صحي واحد في البلاد، تم استخدام تقرير التقييم الخارجي المشترك في قطر (JEE) والدروس المستفادة خلال تجارب One Health حول الأمراض الحيوانية المنشأ والأمراض المنقولة بالنواقل والأمراض المنقولة بالغذاء لتقديم مخطط للتنسيق متعدد القطاعات. بالإضافة إلى ذلك، تم أيضًا تقييم القدرات الفنية لـ One Health والعوامل المطلوبة لتفعيلها في البلاد في سلسلة من الاجتماعات وورش العمل التي عقدت في وزارة الصحة العامة في مارس 2022. وُجد أن البنية التحتية وموارد الرعاية الصحية الحالية تساعد على الإدارة الفعالة والاستجابة للتهديدات الصحية المشتركة كما هو واضح خلال MERS - CoV، على الرغم من كونها أكثر اعتمادًا على الأحداث. وبغض النظر عن ذلك، تم التأكيد بالإجماع على الحاجة إلى تنمية أكثر استدامة للقدرات. كان هناك توافق في الآراء بين جميع أصحاب المصلحة والشركاء المعنيين على أن هناك حاجة إلى قنوات اتصال وسياسات وبروتوكولات أفضل لتبادل البيانات، والحاجة إلى استثمار المزيد من الموارد من أجل استدامة أفضل. من المتوقع أن يعزز الإطار المقترح ويسهل التنسيق متعدد الأطراف، ويعزز قدرة المختبرات وشبكتها، ويحسن المراقبة والاستجابة النشطة، والإبلاغ عن المخاطر، والمشاركة المجتمعية، وتعظيم البحوث التطبيقية، وبناء قوة عمل فنية في One Health. وهذا من شأنه أن يمكّن من تطوير واستدامة أنشطة One Health لمنع التهديدات الصحية المشتركة بين البشر والحيوانات والنظام البيئي والتحكم فيها.
