دراسة إقتصادية لكفاءة إستخدام المياه الإروائية في التنمية الزراعية بمحافظة مطروح

الملخص EN

Agriculture accounts for about 70% of the economic activity in Matrouh governorate, and depends on three main sources: rainwater along the northwest coast, Nile water by the way of al-Nasr and Hammam to the east, and groundwater.

The research aims to try to maximize the efficiency of the use of the water resource in Matrouh governorate by reorganizing the crop structure to achieve maximum net agricultural income using the least amount of water to achieve agricultural and economic development and reduce desertification in Matrouh governorate.

The research dealt with the management of water resources used in agriculture in Matrouh governorate using multi-objective programming, where two objectives were set in the form of maximizing the net agricultural revenue of about 1759 million pounds in actual installation during the period 2017-2019 and the second goal is to reduce the consumption of irrigation water, which is about 600 million m3 used to grow a crop estimated at 393 thousand acres during the same period and several proposed alternatives have been reached, the most important of which has been reached.

The first alternative: some crops have been limited to this alternative, which is to reduce the area of barley by about (20%) It is the largest crop that depends on rain irrigation.

It achieved an increase in total net return of EGP 77 million over the actual net return, with the same needs for the actual installation.

The second alternative: a restriction was put, which is to increase the area of both fig and tomato crops by about 50% from the current composition, to increase the net yield of the two crops, and achieved an increase in the total net return by about 151million pounds from the net actual return, and there is a saving in water resources about 1 million m3 on the amount of water needs for actual.

The fife alternative: The constraints of the previous scenarios were placed first, second and third in a complex scenario through which both maximizing agricultural net income and saving in the amount of water used, and achieving an increase in the total net return estimated at 232 million pounds from the actual net return, and there is an saving of about 9 million m3 for the amount of water needs of the actual.

Based on the results, the study has reached several recommendations, the most important of which are: - Review the crop composition system and guide the proposed fifth model to achieve an increase in total net revenue by about 232 million pounds and achieve an saving of about 9 million m3 water from the actual.
