The Influence of Global Climate Alteration on Nourishment Security in I.R. Iran

Abstract

Climate change, disturbed various dimensions of national security within numerous countries. In the interim, declining the rainfall pattern in those countries which are positioned on the world desert strip, has had the greatest consequence and incidence on their food security sectors. This study objective is to investigate the impact of global climate change on nourishment security. The field study zone of this research is based upon analysis and data which had gathered from Iran. Due to the immensity of the study area, 6 provinces were selected by random sampling technique. To obtain the affiliation between climate change and the current food security complications, the rainfall data and the area under crop cultivation with rain fed planting method, the area under irrigated crops and the number of goats which have raised between 2004-2018 were applied within this research study. The Data which had accumulated was analyzed for variance in the R script environment. The conclusion of analyses of the researched variance showed that the amount of rainfall ratio had a positive and significant result; simultaneously, on the area under cultivation of rain- fed crops as well as the area under cultivation of irrigated crops system. The ratio of rainfall to the number of goats raised, except for the Chaharmahal and Bakhtiari Province, in the remaining states the outcomes were momentous. Henceforth, by generalizing the sample to the statistical population, it can be expressed that the climate change has had a positive and substantial consequence on food security in Iran.Henceforth, by generalizing the sample to the statistical population, it can be expressed that climate change has had a positive and substantial consequence on food security in Iran.
