A Systematic Resilience Approach in the Assessment of the Water-Energy-Food Nexus Security Regions with Extreme Climate Conditions

At present, satisfying the needs of water, energy and food represents one of the biggest problems worldwide due to its poor distribution and the social and environmental disturbances that affect its productivity, availability, and future security. To face these challenges, the concept of resilience was introduced, which has gained great relevance in the field of process engineering to be able to identify vulnerable areas and support decision-making for the use of alternatives so that functionality of the system is not affected. Our aim with this work is to introduce a systematic methodology to quantify resilience in economic terms, which allows us to identify the most vulnerable scenarios to different disturbances, such as random failures, personnel errors, or natural phenomena, to propose modifications to the system that allow to cope its interruptions, in this way, a better operation and management of resources can be carried out. Moreover, it is possible to know the operation of the nexus, especially in regions whit extreme climatic conditions where is difficult to satisfy the water, energy, and food needs. The applicability of the proposed systematic methodology has shown that it is possible to identify the most susceptible scenarios, as well as the scenarios where the loss of functionality due to a disturbance is less. Therefore, it is possible to take corrective actions to maintain the security of water, energy, and food in future scenarios.
