Summary
Introduction:
Water resources are at the forefront of the world’s concerns. The
developed countries have paid great attention to these resources to develop
and maintain them from wastefulness, increase efficiency and maximize
returns. The importance of water resources increases as they become rare
and needed, Egypt as a state of the estuary of the Nile River and with the
scarcity of rains to take the initiative to draw up plans and policies for the
development of water resources to meet the needs and requirements of the
sectors used for water, especially in the field of agriculture to achieve
economic progress desired.
Research problem:
The problem of research in water scarcity in North Sinai
Governorate is summarized. However, there is a large loss of irrigation
water and a lack of rationalization of water use in agriculture, which
impedes the agricultural development process and reduces the agricultural
area and development opportunities and investment in the governorate.
Research hypotheses:
The main hypothesis: There is a significant effect to apply the
method of reducing losses on increasing productivity.
The main hypothesis is divided into two propositions:
- The first hypothesis: There is a significant effect to apply the method
of reducing waste to increase the area cultivated.
Summary

- The second hypothesis: There is a significant effect of the method of
reducing waste on increasing the productivity of the water unit.
Research objectives:
- Identify the impact of applying waste reduction methodology on
productivity improvement.
- Identify available resources in North Sinai Governorate.
- Rationalize the use of irrigation water in agriculture in the desert areas
to increase the area Cultivated by reducing the loss of irrigation water.
- Identify modern methods of irrigation and choose the appropriate
method to reduce losses of water.
- Identify the most efficient crops for water.
- Prepare a proposal to solve the problem of water scarcity and reduce
waste to increase productivity.
Search limits:
1- Spatial boundaries: North Sinai Governorate. The village of
Rummaneh
2- Time Limits: The research papers were completed from 15/6/2013: /
/ 2017 and the field study was 1/1/2016: 31/12/2016.
Search Plan:
The study included four chapters. The first chapter included two
sections: the general framework of the study and the second topic, which
includes the previous studies. The second chapter also included three
topics: the first topic: terrestrial resources, the second topic: water
resources, the third topic: human resources.
Summary

The third chapter ensures the application of the method of reducing
waste and its impact on productivity improvement. The fourth chapter
includes the field study, findings and recommendations.
Research results:
The study reached several results including:
1- There is a fundamental relationship between the application of the
method of reducing waste and improving productivity in all study
sample crops (tomatoes, olives, cantaloupe and pomegranate).
2- There is a fundamental relationship between the application of the
method of reducing the loss and increasing the cultivated area, while
the validity of the hypothesis of the study sample crops (tomatoes,
olives, cantaloupe and pomegranate) has been proven.
3- There is a fundamental relationship between the application of the
method of reducing the losses and increasing the productivity of the
water unit in the study sample crops (tomatoes, olives, cantaloupe and
pomegranate).
4- The study showed that the loss of irrigation water was reduced
through the method of drip irrigation, which in turn led to improved
productivity.
5- A proposed framework has been worked out to solve the problem of
water scarcity and reduce irrigation water losses to improve
productivity.
6- The study contributed to clarifying the reasons that may lead to
increase the loss of irrigation water and how to avoid it.

Search recommendations:
- The study recommends expanding the use of modern methods of
irrigation, especially the method of drip irrigation, which reduced the
losses of irrigation water and improved productivity in the study
sample crops (tomatoes, olives, cantaloupe, pomegranate).
- The study recommends increasing the effectiveness of water resources
to increase the knowledge and culture of water to farmers and to
introduce them to the importance of water resources and its scarcity
by holding seminars and conferences to increase awareness of
farmers.
- The study recommends the necessity of periodic maintenance of
modern irrigation machines, pipes and points in the case of drip
irrigation, sprinklers and pipes.
- It is necessary to choose the appropriate time for irrigation to avoid
water evaporation.
- The study recommends the application of the method of reducing the
losses, where it was reduced losses of irrigation water, which
improved productivity by increasing the area cultivated and increase
the productivity of the water unit.
- Irrigation in accordance with the water parameters of agricultural
crops, as well as selecting the crops that are most efficient in their
water needs.
