The global pandemic that hit the world in 2020 had a profound impact on various economic sectors, especially in developing countries. These countries, which often depend on specific sectors, such as tourism, commodity exports and labor, feel the effects more significantly than developed countries. The tourism sector experienced a drastic decline; many developing countries that rely on international tourist visits are experiencing huge losses. Destinations such as Bali and Thailand, which depend on foreign tourists, felt the direct impact in the form of lost income. This caused many workers in this sector to lose their jobs, thereby increasing the unemployment rate. On the other hand, the agricultural and commodity sectors were also affected. Lockdown policies implemented in various countries disrupt supply and distribution chains, resulting in food shortages. Farmers who depend on access to local and international markets experience difficulties in selling their products, causing significant financial losses. Additionally, developing countries often have inadequate health systems. The inability to deal with the surge in COVID-19 cases is contributing to economic instability. Government spending on health increased, while tax revenues declined due to sluggish economic activity. This triggers a larger budget deficit, forcing the government to take on more debt. Foreign direct investment was also affected. Economic uncertainty makes investors hesitant to invest in countries that are considered high risk. Developing countries are often in a more vulnerable position, making it difficult to attract the investment needed for long-term economic growth. The informal sector, which is often a source of income for many families, is also not free from negative impacts. Many workers in this sector have lost their livelihoods, and have no access to social security. Changes in people’s consumption patterns during the pandemic have caused family income to drop drastically. This socio-economic impact has the potential to worsen inequality. Women and other vulnerable groups may face greater difficulties in accessing education and health. With rising unemployment rates, children from low-income families are at higher risk of dropping out of school. Developing countries are now required to adapt and innovate. Policies that support economic resilience, diversify income sources and develop digital infrastructure are crucial. International support through financial aid and debt relief has also been an important part of helping these countries recover from the crisis caused by the pandemic. These adaptation measures not only focus on short-term recovery, but also create stronger systems to face future challenges. Building food security, encouraging digitalization, and increasing health system capacity are priorities that must be taken by the government and the private sector.
