Predicting a sustainable food safety policy for the near future is among Turkey's priority problems. In this context, this study aims to predict Turkey's sustainable food safety policies. For this reason, the system dynamics model, which is a dynamic cycle-based method with stock and flow diagrams, is used in this paper. This study supposed the six different scenarios for 2020 and 2050. Data were selected as population, productivity rate, arable land fertility rate, and annual food consumption (per capita). The purpose of creating these scenarios; To determine the most appropriate policy to ensure food safety in Turkey. In the first scenario, we assumed that the current situation continues. In the second scenario, the average productivity rate was increased by 1.5%. The third scenario assumes that annual per capita food consumption rises to 1.2 tonnes per year. In the fourth scenario, the total fertility rate is accelerated by 2%. In the fifth scenario, we assumed that the arable land loss rate decreased by 1/3. Finally, we assumed that the sixth scenario covers all the second, third, fourth, and fifth scenarios and that 2 points reduce food losses. In conclusion, the findings show that food security responds positively in scenarios 2 and 6. However, in other scenarios, food security is negatively affected. The findings show that the sixth scenario is the best-case scenario. To ensure food security, it is necessary to reduce arable land losses and food waste. Training farmers and control of the food supply chain will be beneficial for sustainable food security in Turkey. We recommend that policymakers consider these recommendations.

Technological developments and globalization has changed human nature. This change directly affects all stages of human life. At this point, it becomes inevitable to carry out research on people and human life. All studies carried out in the field of Social Sciences aim to understand human, human life and human nature. In this work, which was put forward in order to understand the human, different studies from different disciplines were discussed and a step was tried to be built in order to reach this goal, albeit to some extent. Teknolojik gelişmeler ve küresel anlamda gerçekleşen değişimler insan doğasını değiştirmektedir. Bu değişim insan hayatının tüm aşamalarına doğrudan etki etmektedir. Bu noktada insana ve insan yaşantısına yönelik olarak araştırmalar gerçekleştirmek kaçınılmaz bir hal almaktadır. Sosyal Bilimler alanında gerçekleştirilen tüm çalışmalar insanı, insan yaşantısını ve insan doğasını anlamayı amaçlamaktadır. İnsanı anlamak adına ortaya koyulan bu eserde farklı disiplinlerden farklı çalışmalar ele alınmış ve bir nebze de olsa bu amaca ulaşmak için bir basamak inşa edilmeye çalışılmıştır.

To combat the COVID-19 pandemic, pharmaceutical companies, biotech companies, national governments, and universities have jointly developed a variety of vaccines. After this stage, widespread and effective vaccination on a global scale has become the most crucial aspect in the fight against the pandemic. The discovery of vaccines has brought up the issue of how to deliver them quickly and fairly to those living in underdeveloped countries. Vaccination encompasses not only the medical aspect but also the concepts of accessibility, availability, equitable, fair, and rapid distribution as a whole. The main theme of our study is to comparatively highlight the impact of factors other than the medical aspect of vaccination on vaccination, specifically within the context of the African continent. African countries particularly have faced the most problems in accessing and distributing vaccines. This study aims to identify the barriers to the delivery of the Covid-19 vaccine to African countries. In this study, we analyzed the vaccine supply, governance index, and logistics infrastructure factors affecting access to vaccines in the context of various scenarios, using the system dynamics method. The findings of this study show that income level is the most significant variable. Additionally, improving logistics performance and infrastructure and governance index increase more equitable access to vaccines in African countries.
