1.1 Background to the study

Our activities are inimical to the environment, our daily work and behaviour domestically, industrially and even agriculturally threatens the stability of environment as well as balance of the ecosystem. We often burn bushes to farm, we practice agriculture without due regard to the environment (oil), we cut/fell trees down without knowing that we are altering the eco- system and nature. All these human activities are threatening the nature and at the end, we ourselves are to face the consequences and are to be blamed.

(Professor David Ukali, chairman of NEST, Nov, 2010)

David Ukali’s statement explains how human activities lead to the backlash we experience in our environment today. Man suffers various environmental changes as a result of inappropriate agricultural practices coupled with unscrupulous destructions of various important elements in the environment. Climate change is perhaps the most serious environmental threat to the fight against hunger, malnutrition, disease and poverty in Africa, mainly through its impact on agricultural productivity. Climate change is one of the most serious environmental threats facing mankind worldwide. Climate change may already be impacting Nigeria as manifested by increased flooding, delayed rains, enhanced desertification, increasing bush fires and food insecurity.It affects agriculture in several ways, including its direct impact on food production. Climate change which is attributable to the natural climate cycle and human activities, has adversely affected agricultural productivity in Africa (Ziervogel et al. 2006).

That there is a change in the global climatic system is no longer in doubt. For instance, the periods we used to have rain have changed its proportion in terms of sun rays and that is why it has been generally agreed that this climate change which is posing the greatest threat to man and life on planet earth is gaining acceptance and that in the coming decade the world will witness higher temperatures and changing in precipitation levels which would lead to low/ poor agricultural income. The issue of climate change has become more threatening not only to the sustainable development of socio-economic and agricultural activities of any nation but to the totality of human existence (Adejuwon, 2004). Rough estimates suggest that over the next 50years or so climatic change will likely have a serious threat to meeting global food needs than any other constraints on agricultural system. (IPCC; 2007, BNRCC, 2008).

Available evidence shows that climate change is global; sea level rose about 17 centimetres (6.7 inches) in the last century and the rate has doubled in the last decade, there has been a rise in the global temperature even though the 2000s witnessed a solar output decline resulting in an unusually deep solar minimum in 2007-2009, surface temperatures continue to increase, glaciers are retreating almost everywhere around the world including in the Alps, Himalayas, Andes, Rockies, Alaska and Africa, likewise its impacts but the most adverse effects will be felt mainly by developing countries, especially those in Africa, due to their low level of coping capabilities (Nwafor 2007; Jagtap 2007).

Nigeria is viewed as one of these developing countries (Odjugo, 2010). Nigeria is experiencing adverse climate conditions with adverse impacts on the welfare of millions of its population, as the planet warms, rainfall patterns shift, and extreme events such as droughts, floods, and forest fires become more frequent (Zoellick 2009). Many African countries, which have their economies largely based on weather- sensitive Agricultural production system like Nigeria, are particularly vulnerable to climate change (Dinar et al, 2008). This vulnerability has been demonstrated by the devastating effects of recent flooding in the Niger- Delta region of the country and the various prolonged drought that are currently witnessed in some part of Northern region.

According to Olanrewaju (2003), climatic change is any form of long term climatic inconsistency. The recent changes in the climate have been linked with the increase in greenhouse gases (GHG) on the atmosphere in addition to anthropogenic activities and support emissions of other artificial chlorocarbons (Olanrewaju, 2003).

Climate change is also believed to result from the effect of global warming on the environment. Global warming is regarded by many people to be the most serious environmental challenge of modern times (Giddens, 2006). Global warming refers to the gradual rise of the earth’s average temperature due to changes in the chemical composition of the atmosphere; it is believed to be caused in parts by humans, because the gases that have built up and altered the earth’s atmosphere are the ones produced in large quantities by human activities. Global warming means that many dry areas are going to get drier and wet areas are going to get wetter. “Climate change in Nigeria is a ticking time bomb and it exists little or even nothing to mitigate its effects.”(Nnimmo Bassey, Nigeria.) Peer-reviewed research accepted by the Journal of Geography and Regional Planning concludes that Nigeria’s average temperature has risen by 1.7 degrees in the period 1901-2005. The increase has been higher in the semi-arid regions and lower in the coastal zone; the rate of change has increased since the 1970s.

The consequence for the Nigerian people is a geographical pincer threat from desertification in the north and coastal erosion in the south. Through a combination of overgrazing, abuse of woodland for fuel and increasingly unreliable rainfall, the Sahara is advancing at an estimated rate of 600 meters per annum, rising sea levels threaten Nigeria’s coastal regions the Niger Delta may be the source of oil wealth but its low-lying terrain crisis-crossed with waterways makes it extremely vulnerable to flooding and salinization i.e. the build-up of salts in soil eventually to toxic level for plant.

Food security is the outcome of food system processes all along the food chain; climate change will affect food security through its impacts on all components of global, national and local food system. The definition of food security as adopted at the World Food Summit (WFS) in November 1996 says that; “food security exists when all people at all times have physical or economic access to sufficient safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life” ( FAO, 1996).

One of the biggest threats is growing climate unpredictability, which makes subsistence farming difficult, the impact of the change will be difficult to handle and it will be potentially very long lasting,Droughts are getting worse and climate uncertainty is growing, Climate change is thus an unprecedented threat to food security (Medugu, 2013). Arid and semi-arid areas in northern Nigeria are becoming drier, while the southern part of the country are getting wetter, as the weather gets warmer most of the aquatic life, the fish, tend to seek colder waters thereby emptying Nigeria’s vast waters of marine resources, and which by extension means Nigeria’s reliance on imported fish and other sea foods increases. Climate change often appears very esoteric but in Nigeria; it is real, Currently there is an increasing incidence of disease, declining agricultural productivity, and rising incidences of heat waves (Stringer et al., 2009).

The threat that climate change poses to agricultural production does not only cover the area of crop husbandry but also includes livestock and in fact the total agricultural sector. The impacts of climate change on agriculture can be classified into biophysical and socioeconomic impact (Khanal, 2009). Climate can also affect the quantity and quality of feed stuffs such as pasture, forage, and grain and also the severity and distribution of livestock diseases and parasite (Niggol and Mendelsohn 2008). Climate change impacts the four key dimensions of food security, namely food availability, food stability, food accessibility, and food utilization.

According to vision 2020 as declared by the government of late president Umar Musa Yar’dua in October 2009 stated that; “by 2020 Nigeria will have a large, strong, diversified, sustainable and competitive economy that effectively harness the talents and energies of its people and responsibly exploits its natural endowments to guarantee a high standard of living and quality of life to its citizens” the declared aims of Nigeria’s national agricultural policy are; firstly attain food security, secondly increase production and productivity, thirdly generate employment and income and fourthly expand exports and reduce food imports thereby freeing resources for critical infrastructure development and delivery of social services. To achieve this aims, the problem of climate change as to be curtailed so as to enhance future possibilities of economic development and growth which is the major goal of the country.

1.2 Statement of the Problem

In Nigeria, agriculture has tended to be the main source of food, and a major source of industrial raw material, as well as the means of earning foreign exchange. It employs close to 70% of the Nigeria’s population. Agricultural practice in the country is predominantly rain-fed and therefore particularly vulnerable to the impacts of climate change, and a study report by ( Harvard Business School) HBS in 2010 predicted that under a business as-usual scenario, Nigeria’s agricultural productivity could decline by between 10-25% by 2080, in certain parts a decline in rain-fed agriculture could be as high as 50%, exposure to extreme events makes subsistence and small scale farmers most vulnerable to climate change because of their limited capacity to adapt.

Therefore, Nigeria’s vulnerability will be in two ways:

  1. The resulting impacts of climate change
  2. The impact of response measures this is because Nigeria’s economy is highly dependent on income generated from the production, processing, export and consumption of fossil fuels and associated energy-intensive products.

As a result of the global climatic change, Nigeria has been affected greatly as there has been variations in the weather condition and also the frequent flooding that have led to the destruction of properties and also death of many Nigerians especially in the riverine area of the country.

1.3 Research Questions

The research questions for the study are as follows;

1) What is the relationship between climate change and food security?

2) What has been the effect of global climate change on food security in Nigeria?

3) What is the impact of climate change on food security in Ogun State?

  1. Objectives of the Study

The primary objective is to examine global climate change and how it affects food security in Ogun State, Nigeria. It can be achieved through the following.
