With the global population growing (over seven billion), accompanied by escalating economic crises, mismanagement of natural resources, climatic changes, and uncertainties, and increasing poverty and hunger, the world is opposing critical periods of serious challenges. This paper aims to develop an integrated dynamic model for the WEF system for all governances in the State of Kuwait and future demand with and without climate change. Additionally, identifying proper opportunities in the WEF system in Kuwait. The aim is achieved by building an integrated dynamic model and analyzing it via using WEAP and LEAP software. The business as usual scenario concluded that increasing water, energy, and food within the next 17 years for all governorates. Besides that, climate change will also affect increasingly upon the WEF system. The impact is expected to rise, on average between 2 to 4% in the period 2017-2035 with total cumulative demand about 3144 Mm3. By using several interventions, management policies would help the water, energy, and food system to ensure its sustainability. The several interventions, such as reducing per capita consumption, saving devices, population control, and using reverse osmosis technology, will reduce the demand by about 50% by the year 2035.
