Impact of Climate Change in Nigeria

Climate change is an adverse environmental phenomenon that is causing enormous concern all over the world. It refers to some anomalies in the climate system that is a result of human activities. These anomaliesinclude increase in the concentration of GHGs, HFCs and CFCs in earth’s atmosphere, which will ultimately leadto global warming. In fact, global warming has already begun, as earth’s temperature has risen between 0.4 and0.8°C in the last 100 years. Nigeria is one of the world’s most densely populated countries with a population of 180 million people, half of which are considered to be in abject poverty. Nigeria is recognized as being vulnerable to climate change. Climate change and global warming if left unchecked will cause adverse effectson livelihoods in Nigeria, such as crop production, livestock production, fisheries, forestry and post-harvestactivities, because the rainfall regimes and patterns will be altered, floods which devastate farmlands would occur, increase in temperature and humidity which increases pest and disease would occur and other natural disasters like floods, ocean and storm surges, which not only damage Nigerians’ livelihood but also cause harmto life and property, would occur. The paper provides a strong starting point and a useful guide for furtherinvestigations and solution finding projects, both at the local and international levels which focus on more specific issues like public health, food security, energy, adaptations and barriers to them.
