Water needs have increased dramatically, with the fixed quantity of the main water resource in Egypt at 55.5 billion m3, represented by the Nile River, where the amount of water needs amounted to about 76.25 billion m3, with a deficit of about 20.75 billion m3. The problem of the study shows the increasing gap between the water supply and demand with the increase of population and the increase of water requirements, which leads to a reduction in per capita fresh water to about 846.38 m3 per capita, which is less than the level of water poverty estimated at 1000 m3 per capita. Which has led to the need to study the best ways to manage and use water more efficiently. The study aimed to analyze the impact of virtual water on the Egyptian agricultural trade balance, through several sub-objectives. The study included four main chapters, in addition to the introduction that includes a problem and objectives of the study, data sources and research method, beside to Arabic-language and English-language summary, Arabic and foreign references, abstract, recommendations, and appendices. The crops of the agricultural trade balance were divided into three categories according to their content of virtual water, which are high content crops, which contain more than 2000 m3/ton, and medium content crops, whose content ranges between 1000-2000 m3/ton, Crops of low content, which are less than 1000 m3/ton. Some indicators were used, such as: Gini-Hirschman Coefficient, and Water Intensity Indicator. The Path Analysis Model and Asymmetry and causality tests were used using by NonLinear Autoregressive Distributed Lag (NARDL) method, to measure the effect of the most important factors on both the amount of exports and imports, and the amount of virtual water exported and imported. Linear programming and goal programming were used to achieve optimum scenarios for both export structure, imports and trade balance, with a higher water use and better economic return. The study concluded with some suggested recommendations, then a summary of the most important results, and the references that used to serve the purpose of the study. _______________________________________________________________________________________________

_______________________________________________________________________________________________ • Ph. D. in Agricultural Science: Department of Agricultural Economics, Faculty of Agriculture, Damanhour University, 2020. _______________________________________________________________________________________________ The problem of the study is that there are big marketing differences between the prices that the product gets against production costs and what the consumer pays for the same product when purchasing it. In light of the research problem, a brief indication of the objectives of this thesis can be indicated: Evolution of quantities and prices of the most important vegetable and fruit crops in the Nozha market during the period (2009-2018) Seasonal study of crop prices under study in Al-Nuzha Market during the period (2009-2018) By studying the productive and economic indicators of the study crops in the sample of farmers in the Nubaria region for the agricultural season (2017/2018), it was found that the profits of the pound spent for orange 1.6, grapes 2.5, tomatoes 2.1, and potatoes 2.1 Calculating the profitability of the retailer from the marketing paths of the study sample crops for the same season, it was found to be about 608 pounds / ton for oranges, 682 for grapes, 277 for tomatoes, 295 for potatoes. And by studying the relative importance of the marketing problems of the study crops according to the opinions of marketers in the study sample, it was found that with regard to oranges, the problem of the lack of trained and sorting labor was the biggest problem facing producers by 44%, and for grapes and tomatoes, the problem of increasing collection costs by 76%, 82% for each Of them, for potatoes, the problem of lack of market information was 52% of the opinions of the producers As for the relative importance of the marketing problems of the study crops according to the opinions of wholesalers, the problem of the farmer's lack of interest in sorting and grading operations and the lack of market information was the biggest problem facing merchants by 44%, and for grapes the problem of the lack of marketing structure in the local markets was 44%, and for tomatoes and potatoes it was The high prices of packages and the delay in sales operations are the biggest problems facing wholesalers With regard to the relative importance of marketing problems according to the opinions of retailers for the most important horticultural crops of the study sample, it was found that for oranges, grapes and potatoes, the problem of monopoly of some traders and brokers was the biggest problem facing retailers by 62%, and for tomatoes, the problem of farmer's lack of interest in sorting and grading operations was the biggest problem with 46% of retailers' opinions. _______________________________________________________________________________________________

D. in Agricultural Science (Agricultural Economics), Department of Agricultural Economics, Faculty of Agriculture, Banha University, 2020. _______________________________________________________________________________________________ The study also shows the role of unconventional fodder in increasing red meat production on the one hand and the use of waste and recycling it to protect the environment from pollution on the other hand, so this study is necessary to demonstrate the economic importance of unconventional fodder in the Arab Republic of Egypt and its role in enriching the economic development of livestock in Egypt. The problem of the study is the inability of the productive capacity of the feed resources of farm animals in Egyptian agriculture to cover the animal needs of these resources. This deficit in food for ruminant animals is estimated at about 4.2 million tons of digested foodstuffs. Feeds represent the largest aspect of the cost of animal production in Egypt to meet the needs of The increased demand for it as a result of the increase in population and the increase in the standard of living on the one hand and the increase in healthy food awareness on the other hand despite the increase in the quantities produced from it especially in light of the decline in per capita share from about 11 kg / year in 2000 to about 9 kg / year in 2017, With a permanent gap in the production of red meat amounted to about -618,000 tons, which led to an increased dependence on food imports of animal products in general and red meat products from 1.1 billion pounds in 2003 to about 25 billion pounds in 2017, especially after the liberalization of the exchange rate To meet the necessary needs, which has resulted in an increase in the level of red meat prices that is not commensurate with the income levels, which constitutes an additional burden on the family budget, especially the portion allocated for spending on red meat in Egypt, This is in addition to the reluctance of many producers to work in the field of animal husbandry for several reasons, including the high prices of fodder and workers ’wages, with a deficit in the quantities of those fodder, as the size of the animal feed gap reached about 12.8 million tons of plant feed in the same year, and the severity of this problem increases Due to the shortage of animal feed materials in Egypt, in addition to the waste in agricultural by-products and by-products of some field crops, which are disposed of in negative ways, Thus, these products are treated as a burden that must be disposed of and not an important economic and environmental resource. Therefore, full use of them should be made through the optimum exploitation and recycling in the unconventional feed industry, especially with the continuous increase in the production of these wastes with a gap and deficit in the quantities of feed Animal. _______________________________________________________________________________________________

_______________________________________________________________________________________________ • Ph. D. in Agricultural Science: Department of Agricultural Economics, Faculty of Agriculture, Alazhar University, 2017. _______________________________________________________________________________________________ The Developed countries direct a large part of its production of important food commodities to produce biofuel which led to the creation of economic, social and environmental problems. And this study aims to evaluate the impact of directing of food producing countries to produce biofuel on the Egyptian food security. And it included five sections: the first section entitled ( the study entrance) in three chapters: the first chapter discusses the aim and the problem of this study, the second deals with the methodology and data sources, while the third chapter reviews the previous studies reference and the most important results and recommendations reached . And section two contains the theoretical framework; the third section includes global production and consumption of biofuels, the evolution of global production and trade of food commodities used in the production of biofuels. Section four deals with the most important production indicators and foreign trade for food. Increasing global demand of agricultural products is considered one of the most important factors which subsides the raising tendency for its prices. The research's problem focuses on the global expand in the production of biofuel and its effect on the increase of the Egyptian imports of food crops and the research's objective is to evaluate this effect and the possibility to overcome the supposed increase in the food gap , as a result of increasing the production of biofuel, and the research depends on the quantitative and descriptive statistic analytical methods and its conclusion is that bioethanol is the most produced and consumed kind of liquid biofuel. And now Egypt can't affect the world- neither positively nor negatively – to direct the biofuel production from non-nutritional crops so some methods should be followed to decrease the food gap: Firstly: by vertical extension by using modern agricultural techniques through the optimal economic use of the limited resources either land or water or financial capital resources. Secondly: It's possible to reduce the food gap by rationalizing the consumption by adjusting consumption types of various crops and also to reduce population growth rate. Thirdly: food gap could be reduced by minimizing both production and marketing loss in all agricultural products specially: wheat and rice. It has been referred to some studies which have been working hard to maximizing the reduction in the loss of some crops and also there is an Islamic approach which could be followed in solving the food problem. _______________________________________________________________________________________________
