According to the global attention of conserving the environment and exploiting of its natural resources efficiently, and our limited share of River Nile water that estimated as 55 billion m³ annually, we must find alternative solutions to meet our needs of water resources, and to achieve the strategy of Egypt for sustainable development 2030. Therefore, this research concerns the examination of the potentiality of the benefit from non-conventional water resources in the development process in Sinai, especially at El-Qaa Plain area in Tur Sinai region, also aimed to evaluate the economic and financial dimension of use water resources in the cultivation of "Jojoba" plant due to its high economic and environmental value. Also, use the indicative and descriptive methods, as well as the analytical method of the collected data from different references and interviews, and calculate the economic feasibility of using these water in the cultivation of "Jojoba" by using some standards of economic and financial such as (NPV) and others. In addition to, conducting analyze the inflation impact on the results of the economic and financial analysis to determine the sensitivity of the proposed project's profits to price changes that may happen in the costs and revenues components through project life. The research shows that the project has an ability to withstand market fluctuations and prices change on costs and returns, and it proved that the cultivation of "jojoba" would achieve the expected economic and environmental benefits, which would contribute to achieving sustainable development according to the available water resources in the region.
