Case Study - Nigeria


Nigéria:

The population in Nigeria is more than 170 million people. It is Africa’s most populated country, and one of the most populated countries in the world. The area goes through periods of floods and droughts (Adeoye et al, 2011), and suffers with other issues, such as soil degradation, water and air pollution, and oil spills. The forests are fundamental to provide food and shelter for this massive population, as well as keeping the area less prone to floods and keeping food security by having fertile soils.
         The floods and droughts suffered in the country can be worsened by the deforestation, as trees are responsible for the filtration of the water to the underground, completing the cycle of the water. When there are no trees left to do this process, the floods can happen more often and in a higher intensity. The water and air pollution that the country suffers, which affects the health of people, being a direct threat to human security, can be worsened by the lack of trees, as trees are responsible for naturally capturing the CO2 from the air and releasing it back as Oxygen in the atmosphere. When these trees can no longer do this job, the situation tends to get worse.

Half of Nigeria land used to be covered by trees. Nigeria lost 36% of its forest in the last two decades. The worse of the consequences of Nigerian deforestation is desertification, leading to water scarcity in several areas (Surface, 2009). Water scarcity can lead to conflict over resources in some cases, but it can also be an alarming factor even when there is no conflict. Water is necessary not only for humans but also for agriculture, affecting human security not only directly but also as a factor of food security. The graph below shows the drivers of deforestation in Tropical Africa from 1990 to 2000. Agriculture is a big responsible for these numbers, and it continues to worsen as population numbers rise and more food is demanded to supply all the people. 

                           
            From 2000 to 2005, Nigeria had the highest desertification rate in the world. The desertification leads to water scarcity and soil to be unfertile, and the depletion of trees is leading to an increase in the carbon dioxide of the atmosphere, contributing to global warming. Deforestation counts for 87% of carbon dioxide emissions in the country (Adeoye et al, 2011). This can be a direct threat to human security as food is a very important factor of human security, and when this factor is threatened there is a possible consequence of decrease in food production, combined with an increase in the demand by population growth can create many threats that need to be addressed. The video below shows how people in the area suffered with the desertification in the area and the consequences that it brought to the people. 
                                          
            According to Onyenekenwa (2011), the increase of population comes together with environmental problems, accelerating the deforestation, loss of habitat, species and biodiversity, as well as degenerating wetlands. The connections between environmental problems are connected to deforestation, but the solutions are connected as well, as forests can be not only solution for a fertile land but also lower carbon dioxide levels.
