Climate Change Dynamics and Imperatives for Food Security in Nigeria

Abstract

Decadal variability in African rainfall is projected from General Circulation Models (GCMs) to continue under elevated greenhouse gas scenarios. Effects on rain intensity, spatio-temporal variability of growing seasons, flooding, drought, and land-use change impose feedbacks at regional-local scales. Yet, empirical knowledge of associated impacts on crop yield is limited; thus, we examined the imperatives for food security in Nigeria. Bivariate correlation and multiple regression suggests impending drought in the northern region where livestock farming is predominant. Relative contributions of climate independent variables in determining crop yield by backward selection procedures with stepwise approach indexed the impacts of annual climate variability by a parameter computed as annual yield minus mean annual yield divided by the standard deviation. Results show Z-distribution approximately 5 to + 5, when < 3 or > 3 indicate impacts significant at 95% confidence levels. In conclusion, we established the interwoven relationship between climatic change and food security.

Efek pada intensitas hujan, variabilitas spasial-temporal musim tumbuh, banjir, kekeringan, dan perubahan penggunaan lahan memaksakan masukan pada skala regional-lokal. Namun, pengetahuan empiris dampak yang terkait pada hasil panen terbatas; dengan demikian, dilakukan penelitian untuk ketahanan pangan di Nigeria.

Climate Change and Health Preparedness in Africa: Analysing Trends in Six African Countries

“…Our results revealed that climate change had been extensively experienced within the sampled African countries, with floods and extreme temperatures being experienced in West Africa, mostly in Ghana and Nigeria. The revelation is confirmed by several studies in the reviewed literature of this study [ 50 , 59 , 64 , 65 ]. Drought and extreme temperatures have also been experienced in the Eastern African countries, specifically in Ethiopia and Kenya; meanwhile, the Southern African countries (South Africa and Namibia) also experienced much drought and extreme temperatures.…”

“…The severity of atmospheric warming causes low crop production, which has, in turn, increased food insecurity and shifted the population’s attention to imported food, which affects the livelihood of the vulnerable in Nigeria, South Africa, and Ghana [ 50 , 51 , 52 , 53 ], as well as causing malnutrition among children in Ethiopia [ 54 ]. A study in Ethiopia concluded that about 2.7 million people required emergency food assistance in 2014, while 238,761 children had treatment for severe and acute malnutrition [ 54 ].…”

Climate change and the sustainable development goal on food security: barriers and opportunities for progressive realization in Qatar and Nigeria

“…50 Nigeria spends over a trillion naira annually on food imports: N635 billion on wheat; N356 billion on rice; N217 billion on sugar; and N97 billion on fish. 51 This creates an additional financial burden for the country while increasing vulnerability to price volatility in the global market. Food importation also has safety implications, especially when they come from countries with low safety standards such as China.…”
