Life Expectancy and Nutritive Food Security Cost of Environmental Climate Crisis: An Analytical Appraisal

Abstract

Nutritive food security and good healthy population yields both social and  economic dividends: healthy citizens are more productive, and healthy infants or children develop and perform better in schools with desirable cognitive ability and learning possibilities and, become productive adults in future. Evidence from climate tipping points suggests that the globe is in
a state of planetary and climate crisis emergency with both factors judged to be acute. This planetary emergency requires urgent environmental security (climate crisis security) that contribute to the overall well-being of life, labour productivity and the environmental system to mention a few. Thus, appraising the consequences of the impacts of climate crisis on economic health, food security and labour productivity in Nigeria is very important. Secondary data (1990-2019) were sourced from the World Health Organisation (WHO), Nigeria Bureau of Statistics (NBS), and World Bank. The Vector Auto Regression, Vector Error Correction Model and Granger causality specifications were used for the analysis. Results showed there was a negative relationship among climate crisis, economic health, food security and labour productivity in Nigeria. Therefore, carbon 
emission procures rainfall variability, low agricultural GDP, food insecurity, poor health conditions, and low investment and productivity. Relevant government agencies need to re-strategize climate change resilience and mitigation programmes in order to reduce the impacts of environmental security threat factors, particularly carbon emission, and to adopt low-carbon economy development model.
