The global economic crisis has had a very significant impact on developing countries. One of the most obvious effects is the decline in foreign investment. When economic uncertainty increases, many investors tend to withdraw funds from countries deemed risky, turning to more stable markets. This causes a shortage of capital which is crucial for economic growth. Additionally, developing countries often rely heavily on commodity exports. A global crisis can lead to a decline in international demand, which in turn triggers a decline in commodity prices. This action is very detrimental to countries that depend on income from the mining, agricultural and industrial product sectors. For example, countries in Africa and Latin America experienced a dramatic decline in their export earnings during the 2008 financial crisis. From a social perspective, the impact of the economic crisis can widen social inequality. The problem of poverty will increase as the unemployment rate increases due to companies reducing their workforce to reduce costs. With limited access to education and health, people’s quality of life is increasingly threatened. Governments are urged to take action, but they are often hampered by budget constraints. The health sector has also experienced serious impacts. During crises, health budget allocations are often cut, resulting in a reduction in health services. Infectious diseases could increase, as many individuals are unable to obtain necessary care. This creates a cycle of poverty that is difficult to break. The education sector is not immune from negative influences. With reduced family income, many children are unable to continue their education. This not only hinders individual development, but also hinders the long-term development of the country. An investment in education is an investment in the future, and if disrupted, the impacts will be felt for years to come. Developing countries also often lack adequate policy instruments to overcome crises. They may not have sufficient access to global financial resources that could be used for economic stabilization. With these limitations, their ability to respond to difficulties becomes very limited. Apart from that, interactions with international financial institutions such as the IMF can also be a double-edged sword. Conditions imposed on obtaining loans sometimes undermine economic sovereignty and force countries to implement policies that do not always suit local needs. Climate change also plays a role in exacerbating the effects of the economic crisis. Developing countries are often more vulnerable to natural disasters due to climate change. In crisis conditions, they may lose the ability to build adequate infrastructure for mitigation and adaptation. If we analyze more deeply, we can see that the global economic crisis is not just a short-term challenge. On the contrary, these challenges can change the direction of a country’s development in the long term. In facing a crisis, there needs to be collaboration between developing and developed countries to create more sustainable solutions. Therefore, international cooperation schemes, investment in green technology, and protection of vulnerable sectors are essential to prevent wider impacts. From all this, it is clear that the impact of the global economic crisis on developing countries is very complex and interrelated. Economic and social sustainability will depend greatly on how these countries are able to adapt and collaborate in facing global challenges.
