Tree forests are planted in the desert hinterland around the new cities and Egyptian governorates using treated sewage water (primary or bilateral) to confront the climatic changes that are currently prevailing in the world, reduce environmental pollution by absorbing carbon dioxide from the atmosphere and benefit from the wood product and bio-oils used as bio-improvers for engine and aircraft fuel. Thus, a new agricultural area can be added to be used as a respiratory lung irrigated with treated sewage water. The woody trees and jojoba plants are the most compatible plants with the land and water resources and environmental conditions in Egypt. One of the strategic solutions for the cultivation of the desert backs of the Egyptian governorates, but the expansion of the cultivation of those Plants are limited in what is not commensurate with their economic and environmental importance. The research aimed to study the economics of jojoba plant production and financial feasibility through a financial evaluation and sensitivity analysis of the jojoba seed production farm in the Bayad Al Arab Forest - Beni Suef. B/C) at the discount prices of %8, %10 for jojoba trees without changing the factors of costs and revenues and the life of the project amounted to about 1.59، 1.46 for each of them, respectively, which confirms the feasibility of the project, as the ratio of revenues to costs is greater than the correct one, which means that each pound invested in the project achieves a net return of about 0.61 and 0.53 pounds for each of them, respectively. The net current cash flows or net present value of the project (NPV) amounted to about 67739 and 55025 pounds for each of them, respectively, and accordingly, the payback period for the project's capital was estimated at about 3.3 years, which confirms that there is a speed in recovering the capital. From the above it is clear that the project is economically feasible.
