The study aimed to identify the economic and environmental impact of Jatropha cultivation on the treated wastewater in the Serapeum forest, which has an estimated area of about 8 thousand acres and is located near the treatment plant in Ismailia Governorate, and to identify the possibility of expanding the reuse of treated wastewater in agriculture, as well as to identify the environmental impact. To plant tree forests using treated wastewater
The methods of physical and economic evaluation of unconventional water were used in the cultivation of jatropha trees through some economic and financial criteria, such as net present value (NPV), internal rate of return (IRR), and rate of return to costs (B/C), in addition to conducting a sensitivity test. To determine the sensitivity of the proposed return.
The ability to cope with market fluctuations, especially in terms of costs, was also demonstrated by conducting a sensitivity analysis. The study recommended the need to expand Jatropha cultivation by using treated wastewater due to its positive effects on the environment and increasing national income.
