Challenges of food security in the Gulf Cooperation Council countries: an empirical analysis of fixed and random effects

Abstract

Purpose. This research aims to identify the challenges of the food security indicators in the Gulf Cooperation Council (GCC) countries for the period 2000–2020.
 Methodology / approach. The dataset of this study includes the annual secondary data covering the time 2000–2019 of the six GCC countries. The dependents variables represent the food security indicators whereas, the independents variables (explanatory) represent the challenging factors of the food security at the macro-level data. All the studied variables are reshaped in the balanced panel form; thus, the study uses a long panel, it has many periods (T = 20 years) but few entities (n = 6 countries of GCC) with the total 120 observation. The study applies three alternatives to panel data analysis. 
 Results. The results show that population is a significant driver of food security challenges in the GCC countries. Moreover, food price inflation has a significant impact on the food availability and stability but show no significance on food access and utilization. Fertilizer consumption causes significant problems with food use. The results show that there is an evidence of significant differences in food security across the GCC countries. The random-effects estimators of regression coefficients of food availability and stability challenges are more statistically efficient than those for pooled ordinary least square and fixed effects. While the fixed effects estimators are most preferred for the coefficients of food access and utilization challenges.
 Originality / scientific novelty. Most scientific articles are mostly focused on examining the food security challenges from one separate aspect: economics, climate, or social aspects. Thus, the scientific novelty of the study is to investigate the combination of the food security challenges, social, economic, and agri-environmental factors in the GCC oil countries. 
 Practical value / implications. Through this research, it is proposed that decision-makers embark on interferences that stimulate food security to meet the continual increase in population also future research should be applied to the other factors that challenged food security.

Food insecurity and water management shocks in Saudi Arabia: Bayesian VAR analysis

“…As food insecurity is still a major global challenge [ 35 , 36 ], several empirical studies have investigated the relationship between food insecurity and prices, water issues, GDP, population, climate changes, and drought, among other factors. Drought is among the major factors affecting food insecurity in the world.…”

Economic planning at agricultural enterprises: Ukrainian experience of increasing the availability of data in the context of food security

“…In addition to the positive impact of integrated planning of the activities of agricultural enterprises on the state of food security in the region, a number of scientists [22][23][24] consider the threats that arise in the process of ensuring food security in the absence of an effective approach to planning the economic indicators of agricultural enterprises. At the same time, among the main problems that arise in the process of comprehensive planning of the economic activity of agricultural producers, there is a lack of motivation to conduct independently long-term planning, a lack of involvement in state consulting support programs, mistrust of analytical institutions that collect primary data, etc.…”
