List of Countries Most Affected by Climate Change

Climate Change

According to the World Bank, five main threats arise from climate change; floods, droughts, rise in sea level, storms and agriculture uncertainty. The poor or under developed nations are the ones that are affected by the climate change the most.

Although these countries are have the least share in global warning but they suffer the most because they require external help for recovery. Generally, all countries face the physical effects of climate change to a certain extent but the countries that have large geographies and diversified economies, they are less susceptible. They have better infrastructure and they can easily carry debts at affordable interest rates.

Floods and storms damage infrastructure, destroy the agricultural produce, cause food crises and increase the cost of health. Other than this, it also results in force displacements as many people have to leave their homes to move to a safer place.

Which Countries Are Affected By Climate Change?

Let’s have a look at the countries that are affected by climate change the most:


It is among the nation that is in most danger of facing intense storms which can actually hit 7,000 of its islands. Philippines in the last 5 years has experienced a number of typhoons that caused severe damage. The storms have started hitting new areas too which were never historically affected by climate change. Philippines is vulnerable due to its geography. The country is located in the western Pacific Ocean and it is surrounded by warm waters. The waters get warner when the surface temperature rises up. Other than this, the country also lacks natural barriers. There is nothing standing between its islands and the sea.


10.6% of the population in Cambodia is living 5 meters above the sea level. 35.6% of the GDP of the country comes from agricultural produce. As agriculture farming depends on rain, this sector is quite vulnerable. The country is small and it is close se which makes it highly vulnerable to droughts and floods. Even if the sea level rises by 1 m, it can submerge 56% of the city, damage its infrastructure, agriculture and livelihood.


42.8% of the population in Vietnam is living in the coastal area at the altitude of five meters. 19.75% of the GDP comes from agriculture. Extreme weather events like floods, droughts, typhoons and cold outbreak in the northern regions make the country vulnerable. Furthermore, has a tropical location. The mega deltas and long coastal line make it even more susceptible to damage.


Nigeria’s oil industry is at risk because of climate change. In 2012, 5 months flood caused a loss of 500,000 barrels of oil per day. Niger Delta is the region of the country that is highly exposed to climate change. The rising sea level and rainfall damage the oil wells and food respectively. The rise is temperature between 1.4 Degree C and 5.8 Degree C can have a major negative impact on the social economic wellbeing of the country. Increase in the rainfall, flooding in the coastal area, high temperature, all pose a threat to the health of the people as well as the agricultural produce.


The location of Haiti makes it vulnerable to hurricanes and earthquakes. The series of natural disasters have dented the development of the country along with its ability to prepare for climate change. Other than this, the population has poor basic health care facilities. The infrastructure is inadequate and most of the economy is dependent on agriculture.


Bangladesh lies at the head of the Bay of Bengal, the largest River Delta on Earth. One quarter of the country lies 7 feet above the sea level. Most of the people live along the coastal area to have access to delta soils for farming. The country is largely affected by the sea storms. Another downside is that the land is small but its population is large.


14.8% of the population of Senegal lives on the coastal area. The country typically gets tropical climate. Droughts and floods are one of the major climatic hazards in the country. During the rainy season, floods literally block the streets as a result of which water supply and electricity is suspended for days. Agriculture is highly dependent on favorable climatic conditions and rainfall. When the climate conditions change, the country has to suffer a lot in terms of reduced agricultural produce.


It the sub-Saharan African country composed of desert. It is extremely susceptible to drought which is why the country has to face shortage of food. The population of the country is increasing whereas the supply of food and water is falling short. Haboob is a famous gigantic sand storm that occurs because of rising temperature. It lasts for a few hours but it can destroy not just crops but entire villages. Floods and severe droughts have made Sudan highly unsuitable for agriculture.


The industries of Fiji which are under the threat of climate change the most include fish, tourism and export of sugar. As it is a tropical island state located in the Pacific, the country has to face troubles all year round. The rising sea level cause a damage to the regions nearby. Climate change has made the people of Fiji face severe health problems too.


Although only 6.5% of the population of Mozambique lives in the coastal area but still the country is extremely vulnerable to climate change. The climate conditions have exposed the country to a number of hazards which include floods, cyclones and droughts.  Floods have washed way the roads, bridges and other key infrastructure. 3% of the cultivated land area of the country is lost due to floods. When the sea level rises, especially during the rainy season, the country has to suffer big time. Another issue is that just like other southern African countries, Mozambique is susceptible to wildland fires. All these disasters have impacted the livelihood of the population especially in the rural areas.
