What is Climate in Nigeria?

Nigeria is a country located in West Africa, with a population of over 200 million people. The country experiences a tropical climate, which varies in regions depending on the geographical location, topography, and altitude. Nigeria's climate is unique, and it is essential to understand what it entails to prepare adequately for the weather patterns and the possible effects on human health, agriculture, and the economy.

What is Climate?

Climate refers to the long-term average of weather patterns in a specific region, usually over a period of 30 years. It is the combined effect of various elements, including atmospheric pressure, temperature, humidity, wind speed, and precipitation, that determines the climate. Climate variability and change occur naturally over time, but human activities such as the burning of fossil fuels and deforestation contribute to climate change.

Nigerian Climate Zones

Nigeria has four major climatic zones: the Sahel Savannah, Sudan Savannah, Guinea Savannah, and the Coastal Region. These climatic zones are characterized by different vegetation, rainfall patterns, and temperatures.

Sahel Savannah

The Sahel Savannah covers the northern part of Nigeria, which is close to the Sahara Desert. The region experiences a hot and dry climate for most of the year, with temperatures often reaching up to 45°C. The rainfall pattern in the Sahel Savannah is erratic, and droughts are a common occurrence.

Sudan Savannah

The Sudan Savannah is a transitional zone between the Sahel Savannah and the Guinea Savannah. The region experiences a hot and dry climate during the dry season and a wet and humid climate during the rainy season. The average annual rainfall in the Sudan Savannah is between 900-1200 mm.

Guinea Savannah

The Guinea Savannah covers the central part of Nigeria and is the most extensive climatic zone in the country. The region experiences a wet and humid climate for most of the year, with an average annual rainfall of 1200-1500 mm. The Guinea Savannah is the most suitable region for agriculture in Nigeria.

Coastal Region

The coastal region covers the southern part of Nigeria, which is close to the Atlantic Ocean. The region experiences a warm and humid climate for most of the year, with an average annual rainfall of 2000-4000 mm. The coastal region is prone to flooding due to the heavy rainfall, and this can cause damage to infrastructure and loss of lives.

Effects of Climate on Agriculture

Nigeria heavily relies on agriculture as a source of income, with the sector employing over 70% of the population. The country's climate has a significant impact on agriculture, and changes in weather patterns can lead to crop failure, food insecurity, and economic losses.

Droughts

Droughts are common in the northern part of Nigeria, and they can cause severe damage to crops, livestock, and natural resources. Droughts can also lead to water scarcity, which can affect domestic use and industrial processes.

Flooding

The coastal region is prone to flooding due to heavy rainfall. Flooding can damage crops and infrastructure, and it can also lead to the spread of water-borne diseases such as cholera and typhoid fever.

Soil Erosion

Soil erosion is a significant problem in Nigeria, and it is mainly caused by human activities such as deforestation and poor farming practices. Soil erosion can lead to land degradation, reduced crop yields, and desertification.

Effects of Climate on Human Health

The changing climate in Nigeria has a direct impact on human health. Changes in weather patterns can lead to the emergence and spread of diseases, malnutrition, and mental health problems.

Malaria

Malaria is a prevalent disease in Nigeria, and changes in rainfall patterns can lead to an increase in the number of mosquitoes that carry the disease.

Malnutrition

Changes in weather patterns can affect crop yields, which can lead to food insecurity and malnutrition.

Mental Health

Extreme weather events such as floods and droughts can lead to mental health problems such as stress, anxiety, and depression.

Conclusion

In conclusion, Nigeria's climate is unique, and it varies in regions depending on the geographical location, topography, and altitude. The country's climate has a significant impact on agriculture, human health, and the economy. Droughts, flooding, and soil erosion are some of the major effects of climate on agriculture, while malaria, malnutrition, and mental health problems are the major effects of climate on human health. It is essential to understand Nigeria's climate to prepare adequately for the weather patterns and the possible effects on human health, agriculture, and the economy.
