Abstract EN

Rain is the most important natural resource in drier environments, low rainfall, water scarcity and land degradation severely inhibit the productive capacities of agricultural land in arid and semi-arid environments, so improving rainwater use efficiency is critical in these areas where the rapidly expanding numbers of poor people live in Fragile environment and facing food insecurity and depleting natural resource bases.

Water collection is increasingly important to improve water resource management in such dry environments.

There are water harvesting methods and techniques to provide more water to humans and animals and for irrigation, and in places where rainwater is the only source of water They are important for life, food development, social and economic development, and sustainable environmental services, can alleviate drought stress in arid and semi-arid environments, and contribute significantly to livelihoods and environmental water management by increasing local water supplies and stabilizing crop productivity.

The growing water scarcity caused by the increased awareness, the development of collection materials, and innovative ideas for water storage to Making water harvesting an important, feasible and attractive option for the availability of water resources.

The problem is how we can harness rainwater in the winter season, store it and use it later, instead of using it for irrigation only in the rainy season.

It can be used to irrigate crops Agricultural crops at any time, as well as in daily uses, and how it can be treated to become drinkable, which led to the need for the state to make flood drains, especially in desert areas.

The study aims mainly to study the economic evaluation of the fig crop on some rainwater harvesting systems in Matrouh Governorate, through some of the following sub-objectives, studying the most important rainwater harvesting systems in Matrouh Governorate, evaluating rainwater harvesting systems and their use in agricultural production, identifying the problems and obstacles that hinder rainwater harvesting in Matrouh Governorate, the study relied mainly on questionnaires The questionnaire for the subject of the study by holding personal interviews with farmers of the parchment fig crop under the conditions of rainwater harvesting systems.

The research also relied on the published and unpublished data associated with it.

Closely related to the subject of the study, descriptive and quantitative analysis methods were used to show the economic evaluation of the fig crop grown on some rainwater harvesting systems in Matrouh Governorate.

It was clear from the results of the study that the evolution of the amounts of rain falling on Matrouh governorate during the period (2005-2020) averaged about 114.16 mm, with a coefficient of confluence of about 29.9 mm and the minimum amount of rainfall in Matrouh governorate was about 60 mm, while the maximum reached about 182.75 mm, the study adopted On conducting personal interviews with 86 farmers out of 146 holders according to their use of rainwater harvesting systems (wells, reservoirs, cement dams) by designing a questionnaire to reflect the phenomenon under study, the Marsa Matrouh center was chosen as a study area.

5910,6000 for each of the wells, reservoirs and cement dams, respectively, the proportion of the total variable costs amounted to 37.26%, 54.55%, 58.33% of the total costs of each of the wells, reservoirs and cement dams, respectively, and the percentage of the total fixed costs amounted to 25.48%, 45.45%, 41.67% From the total costs for each of the wells, reservoirs and cement dams, we conclude that the technology of water harvesting system based on cement dams is the largest technology in terms of productivity, reaching about 1500 kg / feddan.

The land of crops in terms of the cultivated area per feddan, where about 60052 feddans are cultivated at the governorate level.

The largest cultivated area is in the Marsa Matrouh center, where about 26,829 feddans are cultivated.

The drilling of wells and reservoirs, the high cost of water harvesting systems, problems related to water quality, high wages of workers, the distance between the system and the activity, the low disposal of water harvesting systems, and the relative importance of each problem varies according to the conditions of the rainwater harvesting systems understudy
