RESUMO

Measurement is critical for assessing and monitoring food security. Yet, it is difficult to comprehend which food security dimensions, components, and levels the numerous available indicators reflect. We thus conducted a systematic literature review to analyse the scientific evidence on these indicators to comprehend the food security dimensions and components covered, intended purpose, level of analysis, data requirements, and recent developments and concepts applied in food security measurement. Data analysis of 78 articles shows that the household-level calorie adequacy indicator is the most frequently used (22%) as a sole measure of food security. The dietary diversity-based (44%) and experience-based (40%) indicators also find frequent use. The food utilisation (13%) and stability (18%) dimensions were seldom captured when measuring food security, and only three of the retrieved publications measured food security by considering all the four food security dimensions. The majority of the studies that applied calorie adequacy and dietary diversity-based indicators employed secondary data whereas most of the studies that applied experience-based indicators employed primary data, suggesting the convenience of collecting data for experience-based indicators than dietary-based indicators. We confirm that the estimation of complementary food security indicators consistently over time can help capture the different food security dimensions and components, and experience-based indicators are more suitable for rapid food security assessments. We suggest practitioners to integrate food consumption and anthropometry data in regular household living standard surveys for more comprehensive food security analysis. The results of this study can be used by food security stakeholders such as governments, practitioners and academics for briefs, teaching, as well as policy-related interventions and evaluations.

RESUMO

Rapid population growth, climate change, limited natural resources, and the COVID-19 pandemic contribute to increased global hunger, necessitating intensive efforts to ensure food security and nutrition (FSN). Previous FSN approaches covered some dimensions, but not all, resulting in significant gaps in food security indicators. The Gulf Cooperation Council (GCC) and the Middle East and North Africa (MENA) regions have received less attention in food security studies, thus far necessitating considerable effort to develop an appropriate analytical framework. This study reviewed articles and international reports of FSN indicators, drivers and policies, methods, and models and extracted the challenges and gaps from the global and UAE contexts. The UAE and the world have gaps in FSN drivers, indicators, and methods, necessitating potential solutions to meet future challenges such as rapid population growth, pandemics, and limited natural resources. As a result, we created a newly developed analytical framework that addresses the shortcomings of previous approaches such as sustainable food systems developed by FAO and the Global Food Security Index (GFSI) and covers all aspects of food security. Gaps in knowledge in FSN drivers and policies, indicators, big data, methods, and models were considered in the developed framework, which has specific advantages. The novel developed framework addresses all food security dimensions (access, availability, stability, and utilization), ensuring poverty reduction, food security, and nutrition security while outperforming previous approaches (i.e., FAO and GFSI). The developed framework could be used successfully not only in the UAE and MENA, but also, globally, helping to solve food insecurity and malnutrition for future generations. The scientific community and policymakers should disseminate such solutions to address global food insecurity and ensure nutrition for future generations in the face of rapid population growth, limited natural resources, climate change, and spreading pandemics.

RESUMO

Food security is a central priority for international policy as one of the world's most significantly urgent targets to achieve. It is considered one of the most pressing issues in many countries, the degree of food security representing the level of self-sufficiency and well-being of citizens. In particular, in the current COVID-19 pandemic era, it has more than ever become a mission-critical goal. In this research, we report on the food security drivers and the current state of recommended policies addressing chronic food insecurity aimed at ensuring the sustainability of future food production. Mapping the determinants of food security contributes to a better understanding of the issue and aids in the development of appropriate food security policies and strategies to enhance the sustainability of food production in all facets; namely environmental, social, and economic. Adopting the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) data screening and selection guidelines and standards, we carried out a comprehensive, reliable, systematic, and rigorous review of research from the last ten years in order to identify the most frequently mentioned drivers and policies of food security in the literature available in two databases: Scopus and Web of Science (WOS). The number of extracted articles was 141 papers in total. An analysis revealed 34 drivers of food security and 17 most recommended policies for the mitigation of food insecurity. The existence of food loss and waste (FLW) policies was the primary driver of food security, followed by food security policies (FSP) in their different forms. However, FSP were the most recommended policies, followed by FLW policies. The identified food security drivers and recommended policies should be used by policy-makers to improve food security, thus contributing to sustainable food production. Our research findings, reflected in the latest version of the Global Food Security Index (GFSI), resulted in more tangible policy implications, suggesting the addition of two dimensions regarding food security. We also identified elements not listed under the GFSI that could be considered in its future revision, including environmental policies/indicators, consumer representation, and traceability throughout the entire supply chain. Overall, it can be concluded that food security is a complicated and multi-faceted issue that cannot be restricted to a single variable, necessitating the deeper integration of various multi-disciplinary interventions.
