The problem of energy in Egypt during the previous period, where all the cities and governorates of the Republic suffered from a severe shortage of energy, whether fuel or oils to operate equipment and machinery to generate power or to produce gas, etc.
The idea of planting trees and plants for the production of energy or fuel such as Jatropha, jojoba, the use of plant waste in the production of gas such as biogas and other sources that are being sought and exploited to produce fuels and oils for the operation of machinery and equipment For the production of energy, and in light of the food gap in Egypt for the lack of self-sufficiency of food, which needs to expand the cultivated areas for the production of food was necessary to move to the cultivation of these plants producing fuel or oils and energy production In land with limited productivity in producing crops, grains, vegetables, fruits and other crops of human food and even clover and barley for the production of animal feed to provide food. The problem is not only in electricity, but in limited oil and gas reserves, especially oil, where the reserve is only around 4.4 billion barrels, Egypt’s production of oil is 560,000 barrels per day and consumption is about 815,000 barrels per day. It is not provided in any sector without the availability of energy. As well as the water problem, which has become very important in light of the continuous population increase and limited Egypt Egypt’s share of the Nile water, which is estimated at 55.5 billion cubic meters and will solve the problem of energy and water in Egypt only in the studied scientific method specialized and one of these solutions to solve the problem of energy, Unconventional water treated wastewater, which accounts for about 10% of Egypt’s share of Nile water for the cultivation of tree forests of Jatropha and jojoba trees for the production of biofuels from wood forests in Egypt.
The study Problem
The main problem is the crisis of energy and traditional fuel and the stability of Egypt’s share of the Nile water with high population density of these sources and lack of renewal, which represents a barrier and a major obstacle to the achievement of integrated development and the trend to search for alternative sources to provide this energy through the use of plants and trees producing energy such as Jatropha, jojoba, etc. using marginal water of limited quality and productivity such as treated wastewater in irrigation and cultivation of these plants.
Objectives of the study
General Objective: To study the return and cost of biofuel production from tree forests in Egypt and to study the financial, economic and environmental feasibility of these forests.
Sub-goals
. An economic study of the production of biofuels through the study of the costs of alternative opportunities for the production of fuel from trees and plants, and the study of the added value of resources available for the use of forest forests for forest production.
2. Environmental study of tree forest uses in improving the environment and reducing pollution rates.
3 - An integrated economic study for the cultivation and production (Jojoba - Jatropha - castor... etc)
4- Maximizing the economic and environmental benefits of the development of biofuel plants using primary and biological treated wastewater in irrigation.
5- Studying the concept and types of liquid biofuels and the reasons for their production.
6. To highlight the economic, social and environmental impacts associated with the production of biofuels
Research Methodology and Data Sources:
The study depends on the statistical method through the descriptive and quantitative analysis such as the simple regression method and multiple in the linear image using Excel and the general time trend equations in the period from 2010 to 2016
Description and presentation of the environmental impact of the presence of forests and fuel-producing trees on the environment
Quantitative statistical method: Based on the description, identification and analysis of the relative importance of the indicators of the study - economic efficiency and elements of production and cultivation of biofuel trees and the financial and economic evaluation of these projects.
Data sources
(1) Data published and unpublished in the governmental and international bodies of statistics - research - reports ...... etc.
(2) Field data prepared and obtained through questionnaires and surveys on the economics of production - alternative opportunities - environmental - economic return in the study areas in both Luxor and New Valley governorates.
