As we observe World Environment Day on the 5th of June, it’s essential to recognize the profound ways in which climate change is reshaping our world, affecting not just the environment but also human lives and communities. One of the most significant consequences of this global phenomenon is the increase in migration and displacement. It is crucial to understand and address the intricate relationship between climate change and migration.
Understanding Climate-Driven Migration
Climate change is not just about rising temperatures. As of 2022, the global temperature had increased by 1.2 degrees Celsius above the pre-industrial average. This warming intensifies other climate impacts, such as droughts, wildfires, and severe weather events. For example, in 2022, more than 170 flood disasters were recorded worldwide, and regions in the United States experienced severe drought conditions, with 85% of the continental area exposed to drought. These extreme weather events, as well as long-term changes to the climate in many places of the world, cause people to migrate.
Human mobility linked to environmental changes is not a new concept. However, the accelerating pace of climate change is intensifying both internal and international migration and displacement. The effects can be direct, such as the drought in Somalia in 2022, which displaced over a million people within the country. Alternatively, the impacts can be more indirect, where rising global temperatures threaten livelihoods and compel migration, as seen in rural Honduras and Guatemala.
Despite dramatic predictions, the reality of climate-related migration is often currently more nuanced. At the moment, most movement due to climate change and natural disasters is internal rather than cross-border and temporary rather than permanent. In 2022, there were 33 million natural disaster-related displacements globally, primarily due to floods in Pakistan and droughts in East Africa. Yet, most of these displaced individuals moved within their countries and eventually returned to their homes by the end of the year.
Case Study: Pakistan’s 2022 Floods
A poignant example of climate-induced migration is the 2022 floods in Pakistan, which displaced an estimated 8 million people and caused around $30 billion in damages. Initially, the movement was internal as people sought higher ground. However, the floods exacerbated existing economic struggles, leading many Pakistanis to migrate to Europe, taking dangerous routes. This underscores how climate disasters can compound economic issues, driving broader migration trends.
The Long-Term Impact of Gradual Climate Change
While sudden natural disasters prompt immediate displacement, slow-onset climate changes, such as rising sea levels and increasing temperatures, pose a long-term threat to livelihoods. These gradual changes can lead to more permanent and potentially large-scale migration. The World Bank predicts that up to 216 million people might be displaced internally by 2050 due to water scarcity and agricultural threats. However, effective government action on climate mitigation and adaptation could reduce this number by around 80%.
The Role of MOAS in Climate Advocacy
At MOAS, we are dedicated to raising awareness about the impacts of climate change and advocating for mitigation strategies through our social media campaigns. Our efforts aim to highlight the importance of addressing the root causes of climate-induced displacement and supporting sustainable solutions for vulnerable communities. We also support communities impacted by extreme weather phenomena, such as drought in Somalia or flooding in Bangladesh, through our programs to combat malnutrition and respond to disasters.
Final Thoughts
As climate change continues to reshape our world, understanding its impact on human migration is crucial. While not the sole driver of migration, climate change increasingly intersects with economic and social factors, amplifying displacement and migration pressures. Addressing these challenges requires comprehensive policies and international cooperation to mitigate climate impacts and support affected populations.
By staying informed and advocating for change, we can work towards a future where communities are resilient to climate impacts and where migration is a choice, not a necessity.
