In order to create a new appropriate tool that would embrace all the required aspects of food calculation and production raise in Abu Dhabi (UAE), it is essential to consider the existing models including their parameters and limitations and suggest a combination of tools.

The limitations of Climate, Land, Energy, and Water strategies (CLEW) comprising the extended scope of analysis and complication of the tool due to its coverage of four interlinked components allow envisaging the similar situation for a new tool. Therefore, to make the system less complicated, it is significant to distinguish the areas of analysis between several responsible departments and persons. What is more, such limitations as the lack of frequently updated data and driving forces of the land of the Global Agro-Ecological Zones (GAEZ) model make to reflect on the enhancement of the principles of land assessment. In particular, the frequently updated data would be the best decision to overcome the above mentioned gap.
Based on the present models, it seems that the new tool should be mostly connected to the Energy and Water Food (WEF) nexus tool 2.0. The energy and water are paramount aspects of food production as well as the parameters of the population growth, changes in the economy and climate. However, the linearity, static character, and local consideration are the limitations that should be overcome by means of enhancing the parameters.
For instance, it seems suitable to expand the area of coverage and pay attention to the global context that might affect the food production. Besides, it is also important to consider the interrelation between the mentioned parameters as they might impact each other nonlinearly. The last but not the least, the parameter to be improved is the static character as the energy and water coefficients tend to vary eventually.
It should also be pinpointed that there are some parameters to add in the tool that were not mentioned in the considered models. Thus, the thorough land evaluation that would include the pH level, soil airiness as well evaporation coefficient might vastly increase the food production and promote accurate calculations. Another parameter is the labor development that is an intensive system of mandatory implementation of measures covering the entire process of obtaining a high production including high labor discipline along with strict technological discipline.
It would assume the effective use of all the factors determining the food production in the framework of workers’ labor: tillage, fertilizer system, proper crop rotation, integrated system of plant protection using agronomic, biological, and chemical methods, reclamation control techniques of soil fertility and water regime, and other modern technological means.
To sum up, the new comprehensible food nexus tool should involve all the aspects that were counted above and integrate them appropriately. The suggested model is essential for Abu Dhabi as it takes into account the considerable issues connected to the food production increase and calculation. The model focuses on peculiarities of the region such as water, energy, and land and recommends the ways to overcome some limitations of other existing tools. Moreover, the suggested food nexus tool considers some innovative parameters that are applicable and valid for Abu Dhabi such as land evaluation and labor development. Accordingly, the new comprehensible model seems to be the best one to resolve the issues of food calculation and production in Abu Dhabi.
