Report Predicts Sharp Increase in Climate Migration by 2050 as Climate Challenges Escalate

Recurring droughts and severe floods are increasingly disrupting life in East Africa. Regions like Turkana, Marsabit, and Garissa are grappling with these crises, forcing communities to search for water and pasture. Meanwhile, families along the Tana River face displacement due to flooding.

A recent report titled the State of Africa’s Environment 2025 highlights that local struggles reflect a broader problem across the continent. It predicts that by 2050, up to 100 million people in Africa might be compelled to migrate because of climate-related stress. The report, created by the Centre for Science and Environment (CSE) in partnership with other organizations, emphasizes that Africa’s young population is particularly vulnerable. With a median age of just 19, many of these youths may find themselves adapting to drastic environmental changes, often leading them to migrate.

From 2015 to 2024, global disasters led to nearly 265 million displacements, with around 90% linked to floods and storms. Africa has faced significant impacts, seeing a threefold increase in internal displacements over the past 15 years. In fact, over 75% of these displacements were due to flooding, while droughts accounted for about 11%.

During rainy seasons in Kenya and eastern Africa, climate-related displacements tend to peak. For example, in early 2024, heavy rains displaced over 500,000 people in just a few months. By the end of that year, approximately 185,000 remained displaced due to ongoing drought conditions.

Experts refer to this growing trend as “climate mobility.” It’s a way for people to cope with the changes around them. According to the Intergovernmental Panel on Climate Change (IPCC), while migration can provide short-term relief for many families, success heavily relies on social and economic contexts. Most people in Africa migrate short distances within their countries rather than crossing borders. Often, they move to nearby towns or safer rural areas.

Notable disasters, like Cyclones Idai and Freddy and ongoing droughts in the Horn of Africa, showcase the rising challenges ahead. By 2050, the International Organization for Migration estimates that up to 200 million additional people worldwide could become “environmental migrants,” with Africa playing a central role.

Sunita Narain, director of CSE, emphasizes the urgency of tackling this issue. She states, “The question is not if millions will move, but how communities and governments will prepare for this inevitable change.” Each year, extreme weather events seem to break previous records, underscoring the critical need for action.

Recent statistics from the UN Refugee Agency also resonate with these findings. On average, weather-related disasters have caused about 60,000 displacements daily in the past decade. As detailed in the UN’s World Migration Report 2024, while climate change isn’t the sole cause of migration or food insecurity, it exacerbates existing problems related to governance and economic inequality.

Overall, as we confront these environmental challenges, understanding the connections between climate change and migration is vital. It’s a reality that requires immediate attention and proactive measures.
