Abstract
It is very well known that Water, Energy, and Food (WEF) are strictly interlinked in a non-simplicate manner. Towards achieving sustainable development, the WEF nexus has to be managed in an innovative style that maximizes the diverse benefits from each component in one hand and from all of them combined in the other hand considering the different socio-economic and environmental dimensions.
Here, a detailed conceptual design of a GIS-based modelling system for WEF nexus management is described that considers various characteristics for each component. On that basis, the developed system adopts an innovative approach in connecting several modelling components such as GIS, numeric databases, and equation solvers’ modules.
The designed system was tested by applying it to regions within the Egyptian national 1.5 million feddan project to demonstrate the developed modelling system’s applicability. The current Thesis is on the conceptual design of the modelling system, introduce as a comparison to alternative approaches and providing an evidence base for the choices made. The usability of the tool is demonstrated with a case study in Moghra and West of West Minya regions, Egypt.
For this purpose, three sets of scenarios were described. S1: The first scenario analyses the effect of area size, S2: the second scenario discusses the effect of different crop types, while S3: the third one addresses the impact of the location of the farm. The results of S1 showed the impact of the change in the farm area on water consumption, energy consumption and food production. The effect of the farm area on water consumption was linear. On the other hand, the parameter of the indirect energy consumption was nonlinear. S2 results compared the impact of the change in the crop types on water and energy consumption. Due to different crops, planting dates and growth durations affected the results and were noteworthy. S3 results showed the effect of the location of the farm when the other inputs were fixed, due to the change of the values connected by the location like evapotranspiration, water quality and groundwater level .etc, The energy and water consumption have different results for the same crop.
Based on the results of the three scenarios, and considering the easiness of the model it is proven a helpful tool. Stakeholders can include their data in the model to design their scenarios in order to get quantitative and spatial information of the WEF nexus.
