Ten Countries At Most Climate Risk

Climate change is causing new humanitarian crises and accelerating existing ones in vulnerable communities around the world. Which countries are at most risk of climate disaster? A new analysis  International Rescue Committee (IRC) shows that ten countries are at most risk.

“The world’s most vulnerable populations are already on the frontline of the climate crisis,” explains IRC CEO and President, David Miliband. “To curtail the worst climate and extreme weather disasters, major-emitting nations must take drastic actions to rein in emissions.”

Here we take a look at the ten countries; 


Climate change has had a devastating impact on Somalia, worsening challenges of drought and extreme food insecurity. The country’s political instability has made it difficult to address its climate crisis and protect vulnerable communities. By mid-2023, more than an estimated eight million Somalis – nearly half of the country’s population – will be experiencing crisis levels of food insecurity, or worse.


Over a decade of war in Syria has eroded the country’s ability to respond to crises. The conflict and an intense economic crisis have forced 90% of Syrians below the poverty line. Extreme drought and the February 2023 earthquake near the Syrian-Turkish border, which affected hundreds of thousands of Syrians, have highlighted the challenges associated with responding to emergencies in a country facing high fragility.


The Democratic Republic of Congo is experiencing persistent conflict, economic challenges and disease outbreaks. Over 100 armed groups fight for control in eastern Congo, often targeting civilians. Major disease outbreaks–including measles, malaria and Ebola– pose an ever present threat to a weakened health care system, putting many lives at risk.

These factors have weakened the country’s ability to prepare the country for climate disasters and disrupted humanitarian support while citizens face floods and rising food insecurity.


Since the Taliban became Afghanistan’s de facto authorities in 2021, the country has experienced growing fragility as a breakdown in foreign aid flows and an economic collapse deepen poverty. Now, Afghanistan has entered its third year of drought while intense flooding in some parts of the country has diminished food production and driven people from their homes.


Years of conflict have driven an economic crisis and high levels of fragility in Yemen. By the end of 2022, 17 million people in Yemen required food assistance, while 1.3 million pregnant or breastfeeding women and 2.2 million children required treatment for malnutrition. Climate change has worsened desertification and drought in the country.


Chad ranks as the world’s most climate-vulnerable country on the Notre Dame-Global Adaptation Initiative Index, which examines a country’s exposure, sensitivity and capacity to adapt to the negative effects of climate change. Flooding in late 2022 affected more than 1 million people in the country while an economic crisis has led to widespread food insecurity. Growing conflict and tensions related to the country’s Transitional Military Council have limited progress in building climate resilience.


South Sudan, a country with high fragility and low climate readiness, is increasingly vulnerable to climate disasters. While the civil war that rocked the country officially ended in 2018, local conflicts remain widespread. Better climate resiliency is needed to protect South Sudanese citizens from climate shocks, like the severe floods which affected over 900,000 people in late 2022.


Competition for control over political power and natural resources has destabilized the Central African Republic (CAR). Severe flooding threatens the safety and health of CAR residents, particularly those living in camps for internally displaced people, by contributing to the spread of water-borne illnesses like cholera. Other diseases like malaria, meningitis and monkey pox also strain CAR’s weakened health system.


Flooding in late 2022 affected 2.5 million people in Nigeria and caused extensive damage to the country’s farmland. By mid-2023 an estimated 25 million Nigerians will face high levels of food insecurity. Political tensions and widespread conflict have contributed to the country’s fragility, making it difficult to respond to climate disasters.


Drought is affecting more than 24 million Ethiopians. This number is expected to rise as the country is set to enter its sixth consecutive failed rainy season. Numerous conflicts across the region and political instability have disrupted humanitarian support in the country. This made it difficult for authorities to address the impacts of climate change on Ethiopia


The IRC and the World Resource Institute(WRI) analyzed where climate crises are likely to occur. They also looked at whether affected countries have the capacity to respond and protect vulnerable communities.

They said that countries with low levels of climate readiness and high levels of fragility are most at risk of climate disaster. Climate readiness is measured by examining the threats that climate change poses to a country and that country’s ability to protect its citizens from, and build resilience to, climate disasters. Meanwhile, fragility is the likelihood that a country will collapse and become unable to govern or provide services to its citizens.
