هدفت الدراسة إلى التعرف على مدي إمكانية محافظة الإسماعيلية في التوسع بزراعة الغابات الشجرية لتصل مساحتها إلى نحو 8 ألف فدان بإضافة نحو 7500 فدان جديدة تزرع كغابات شجرية وذلك من خلال التعرف على مدى توافر الأراضي الصالحة لذلك الغرض (الظهير صحراوي للمحافظة)، وكذلك التعرف على مدى توافر مياه الصرف الصحي المعالج واللازم لري هذه المساحة المراد استغلالها في زراعة الغابات الشجرية، واعتمدت الدراسة على البيانات والإحصاءات المنشورة وغير المنشورة والصادرة لبعض الجهات مثل وزارة الزراعة واستصلاح الأراضي، ووزارة الموارد المائية والري، ووزارة البيئة، والجهاز المركزي للتعبئة العامة والإحصاء وإدارة مشروع غابة سرابيوم، وديوان محافظة الإسماعيلية. واستندت الدراسة في تحقيق أهدافها إلى كل من أسلوبي التحليل الوصفي والكمي، بالإضافة إلى ذلك فقد تم استخدام معايير الكفاءة الجزئية ومعايير الكفاءة الشاملة لقياس كفاءة استخدام الموارد المائية والاستثمارات، وأوصت الدراسة بضرورة سرعة العمل على التوسع في إقامة الغابات الشجرية بمحافظة الإسماعيلية وذلك وذلك لما لها من أثار إيجابية على البيئة وكذلك لما توفره من نواتج تساهم في زيادة الدخل القومي، وسد احتياجات السوق المحلى من الأخشاب، وأيضا أوصت الدراسة بضرورة تخصيص مساحات كبيرة لزراعة الأشجار الزيتية مثل الجوجوبا والجاتروفا وذلك لارتفاع العوائد المتحصل عليها من بيع زيوت بذور هذه الأشجار. The cultivation of forests with their properties is considered to be the neighborhoods of sewage water, their general and general conditions, their souls, their security and their souls. An area of about 500 acres is irrigated with treated sewage water, and it is planted with multiple varieties of woody trees, including cypress, conifers, jatropha, kaya, jojoba, bumpo and other economic trees. Which works to increase the added value and economic return on national income as a result of the exploitation of wood trees in purifying and packing oils from the seeds of jatropha or jojoba trees, which are used in the production of biofuels and oils, furniture and housing factories, and charcoal from the cultivation of kaya trees, cypress, casuarina and conifers. The study aimed to identify the extent of the Ismailia Governorate’s potential to expand the cultivation of tree forests to reach an area of about 8 thousand acres by adding about 7,500 new acres to be planted as tree forests, by identifying the availability of suitable lands for that purpose (the desert back of the governorate), As well as identifying the availability of treated sewage water necessary to irrigate this area to be exploited in planting arboreal forests, as well as identifying the current status of arboreal forests in Ismailia Governorate in terms of area, planted trees and their economic value, and getting acquainted with the job opportunities provided by the currently planted forests and the expected job opportunities By increasing the space to the desired area. As for the research problem, it was, in light of the state's plans to promote agricultural development, it was necessary to pay attention to planting tree forests and expand their cultivation in governorates with a large desert hinterland such as Ismailia, due to the important environmental, health, and economic impacts of these forests, including improving air quality. Whereas the main product of the tree forest is wood and the prices of these wood vary according to their quality and by calculating the amount of wood production according to the years of harvest and according to the price of each of them, it was found that the revenue from cypress, pine and kaya amounted to about 142.5, 127.8, 96.25 thousand pounds. And camphor, conocarpus and bamboo amounted to about 155.68, 221.4, 67.6, and 70 thousand pounds each, respectively. As for jojoba and jatropha, the main crop of them is the oil extracted from their seeds, so the revenue from their wood was insignificant, amounting to 1.2, 0.88 thousand pounds, and this compensates for their oil production, as shown in Table No. (7), where the total production for them of oils is about 1.2, 0.8 Tonnes for each of them, respectively, annually, and according to the global average price of 4 thousand dollars per ton, the expected revenue from oil production may reach 744 and 496 thousand pounds for each of them respectively during the ten years of harvest. It is evident from all the criteria of partial efficiency and overall efficiency that the oil trees (jojoba, jatropha) have great superiority over the rest of wood trees due to the high revenues resulting from them, due to the use of these tree oils in the manufacture of aircraft oils, which calls for the need for the state to expand the cultivation of these trees for its great profitability. |
