    Due to the fact that most of the food in Qatar are imported from different countries around the world, and given the so-called GCC crisis in 2017, there is a strong need to focus on sustainability impacts of the embargo in term of food security, sustainability and climate impacts in Qatar. This thesis presents an analytical approach to analyze Qatar’s food trade for the period between 2013 and 2018. Furthermore, measuring and managing the CO2 emission and equivalences from freight transport operations for the period 2015 to 2018. The carbon footprint was calculated using the transport CO2 emission analysis and a global Multi-Region Input-Output (MRIO) analysis. The data was carefully stored on a database using MySQL. Then, the data was retrieved using the data visualization tool, the Microsoft Power BI. The results indicate that imported food to Qatar was highly dependent on Saudi Arabia and the United Arab Emirates over the past years. However, there was a huge reduction in the supply chain from those countries after the embargo. Consideration of the supply chain design network that takes global CO2 emission into account is important. There was a significant change in trade data. On the other hand, the total amount of carbon footprint decreased from 2015 to 2018 with around 320,000 tons of CO2 emission. The consumption of MRIO-Raw milk and MRIO-Dairy decreased as well from 2015 to 2018. However, the CO2 emission using the air mode increased sharply from 2015 to 201

    Embarking on the World Cup journey with circular collaborative strategies can positively impact the environment and socioeconomic outcomes to prosper development at the center of sustainability. World Cup mega-events are set with overriding priorities in cutting down environmental footprints to accelerate sustainable development across the FĂ©dĂ©ration Internationale de Football Association movement to leave an enduring legacy post-event in global sports. This paper conducts the first of its kind comprehensive critical analysis on ecological quality in life cycle impact assessment for 2022 FĂ©dĂ©ration Internationale de Football Association World Cup modular container stadiums in Qatar. A “cradle-to-cradle” life cycle assessment, including the material and resource production, construction, operation, and end-of-life (EOL) phase, is analyzed in this study, taking the case of Ras Abu Aboud stadium. Ecoinvent v3.7.1 life cycle inventory database was used to quantify the ecosystem damage-related impacts. Two scenarios were considered for the operation phase: scenario 1 (single year of operation) and scenario 2 (30 years of operation). A sensitivity analysis was used to understand the extent of impact per category indicator subject to material quantity variations. The results showed that the planned circularity contributed to savings in the EOL phase of more than 4.26 × 107 species.year compared with 1.7 species.year across the overall life-cycle impacts. Several perspective-based circular and sharing economy scenarios were assessed to reveal the benefits of circular collaborative economy applications in leveraging possible ecological burdens before, during, and post-mega events in sustainable construction. This research acts as a backbone for future single-sport mega-events to attempt to transition to a carbon-neutral, fully sustainable event with an everlasting legacy

    SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

    Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population
