The impact of the global economic crisis on developing countries is clearly visible in various aspects, including social, economic and environmental. When a crisis hits developed countries, the domino effect often spreads to more vulnerable developing countries. Below are some of the main impacts that occurred. First, economic growth is hampered. Developing countries rely heavily on exports of goods and services. The decline in demand from developed countries means that sales of their products also decline, which leads to a slowdown in economic growth. Data shows that countries such as Indonesia, Brazil and India are experiencing slowing GDP growth due to falling global demand. Second, the increase in unemployment has become a general phenomenon. In crisis conditions, many companies reduce their workforce or even go out of business. The informal sector that dominates developing countries’ economies has been badly affected, causing millions of workers to lose their livelihoods. This contributed to increasing social instability, with protests and public discontent breaking out in various cities. Third, inflation increases. Price increases for basic goods such as food and fuel have become more common during the crisis. Developing countries that lack foreign exchange reserves are vulnerable to international price fluctuations. Household spending is increasing, and people’s purchasing power is decreasing, resulting in a severe cost of living crisis. Fourth, access to credit and investment is hampered. When a crisis hits, many investors tend to withdraw their investments from developing countries due to economic uncertainty. Banks have become more selective in providing loans. This has a negative impact on small and medium-sized businesses that need financial support to survive. Fifth, the social impact is no less significant. Economic crises often lead to increased poverty and inequality. Data from the World Bank shows that more than 100 million people could fall into extreme poverty due to the impact of the global crisis. Education and health are also disrupted due to limited resources, hindering the development of future generations. Sixth, vulnerability to climate change increases. Many developing countries face major challenges in terms of climate change. The economic crisis diverts attention and resources from environmental mitigation and adaptation efforts. When the economy is tough, investing in sustainable energy and building green infrastructure is often overlooked. Seventh, decline in international support. Developing countries often depend on foreign aid. However, in times of crisis, donor countries also experience economic pressure, resulting in reductions in international aid budgets. This can hinder important development projects, such as infrastructure and health. Finally, trade isolation and growing protectionism may increase. Developing countries could become caught up in a broader trade war, losing access to international markets. Protectionist policies in developed countries have the potential to damage export opportunities. According to a WTO report, the spread of protectionist policies could reduce global economic growth by up to one percent. The impacts of the global economic crisis are complex and varied, but what they have in common is the creation of serious challenges for developing countries. Recognizing these dynamics, it is important for policymakers to develop effective adaptation strategies to minimize the negative impacts of this unexpected situation.
