EVALUATION OF THE PRODUCTIVITY,EFFICIENCY AND RESILIENCE OF FOODPRODUCTION SYSTEMS DURING THE COVID 19PERIOD (2020-2022): A CASE STUDYFOR GLOBAL REGIONS

Abstract

To operationalize the term resilience in food systems, it is necessary to indirectly quantify this attribute, so that the impact caused by external phenomena can be measured. One way to think of resilience is in terms of maintaining productive efficiency over time. It is assumed that resilience is an intrinsic property of complex adaptive systems, which should be measured as a comparison across time of the behavior of the system under study (time series) and comparing similar cases (data panels). This paper integrates the concepts and results of econometric analyses based on total agricultural production (TFP), data envelope analysis (DEA) and Malmquist index to identify nations that in the period from 2020 to 2022 serve as an example in terms of maintaining their productive efficiency under adverse contexts such as the COVID pandemic. The results are discussed with a complex adaptive systems approach.
