European Union countries are considered most important markets for imported Egyptian potatoes, and despite of that, the quantity of Egyptian exports from this crop is not appropriate with the export potential of Egypt. The study aims to identify the current status of Egyptian potatoes exports to the European Union, a study of the competitive situation of Egyptian potatoes in the most important markets within the European Union and finally, estimate the demand function of Egyptian potatoes in the most important EU markets. The study concluded that Italy and Greece are the most important EU markets importing Egyptian potatoes. This amount was about 64.3%, 66.8% of the average total quantity and value of Egyptian exports of potatoes to the European Union during the period (2000-2014) respectively, and their imports increased annually at different rates during the period (1995–2014). The market share of Egyptian potatoes within the EU market is very small with the exception of the Greece market and the Italian market.   Based on such results, the study recommends the following   Focus on increasing exports of Egyptian potatoes to countries with a high volume of imports of potatoes such as the Netherlands, Belgium, Spain and France. To review the prices of potatoes exports to Italy and the most suitable periods of increasing its quantity to this market, taking care that this does not put the Egyptian potatoes in a price competition with French and German potatoes. Continuation and further work on improving the quality of potatoes, in addition to the expansion in the cultivation of potatoes in the brown rot-free, so as to benefit from competitive advantages in the markets of the EU, especially Italian and Greece markets, making it possible to sustain Egypt's share in both markets, and take advantage from the price competition in the Greece market. Necessity follows flexible price policies for the Egyptian potatoes exports to Greece, which could increase its exports to this market and take advantage of price competition in this market. Necessity continue studying the ratio between export prices of Egyptian potatoes to the markets of the EU, and the export price for countries competing in these markets in general, and each of the Italian and Greece market in particular. So as to achieve the continuity and stability of this ratio, or at least achieve the stability of the quantities exported of Egyptian potatoes to both markets at the same time. Studying the prices of potatoes and seed special analytical study as Shafik in a study. Abolition of government intervention and control of prices, as Wali pointed out in the study of the abolition of control of prices and reduce supply. Abdul Rahim also mentioned in this study the effects of the liberalization of the prices of agricultural inputs and outputs on crop composition. Find alternatives to price policies for the development of Egyptian potatoes as a strong competitor in the European market with a competitive advantage price, as indicated by Azza in the study of alternatives to agricultural price policy and the effects of the Egyptian economic. Put the potatoes in the composition of a crop compatible with contemporary economic variables as explained Abdel-Maksoud

Agricultural foreign trade represents an important place in the total foreign trade for its contribution to the amount of change in the deficit in the trade of agricultural balance plus or minus, and thus change the extent of the deficit in the trade balance, and foreign trade which reflects the production, consumption and investment variables through the evolution of exports and imports. The problem with research in the State to take a lot of policies that help the development of exports and reduce imports of agricultural ones especially, but he agricultural exports did not achieve its objective which reflects the weak economic performance in the trade deficit, and the goals of research identify the evolution of exports and imports of the subject of the study crops, and the study of the economic efficiency of the Egyptian agricultural foreign trade through the relative importance of exports and imports of agricultural goods through the international exchange rate, and estimate the total agricultural foreign trade efficiency, which Based on appreciation to a number of indicators including coverage rate, dependency ratio, the degree of economic participation. According to the results obtained, the average coverage of trade overall rate was about 43.86%, while the counterpart of agricultural trade amounted to about 41.2%, indicating a lack of total agricultural exports to the requirements of the total and agricultural development cover, also results indicate that the average economic dependency of the trade rate total amounted to about 56.92%, while the counterpart of agricultural trade amounted to about 15.3%, which indicates a decline of agricultural dependence on counterpart rate at the national level, and reached the total average degree of economic participation of trade about 40.39%, while the counterpart of agricultural trade amounted to about 43.7% which refers to the coverage of agricultural trade to the proportion of 92.5% of total trade, also indicate a net food balance and the ratio of exports of food imports to the existence of permanent disability in food balance statistics, has been the exchange rate decreased commodity crops study namely rice, wheat, maize, dry beans and potatoes to less than one is true, which means that the exchange rate in an invalid state and this would lower real income and the low level of well-being as a result of lower exports of these crops and this is due to the obstacles facing agricultural exports, and recommended research need to take care of software development and support services for agricultural exports from the structure key export and activating the agreements, and the expansion of agricultural projects that produce for export.

The problem of fish food security is represented in insufficient strategic stocks of fish, especially in light of the increasing demand for fish, and lower production than consumption. The research mainly targeted the study of the situation of fish food security in Egypt, in addition to a set of sub-goals, which are the most important that the estimation of both the strategic stock of fish and fish food security coefficient in Egypt, studying of the most important factors affecting fish food security, studying of future expectations for fish food security, This is in addition to studying the problems that Obstruct the continued increase in fish production. The research relied on achieving goals on the use of qualitative statistical methods and economic equations for estimating both strategic stocks and security coefficient for fish. As Quantitative statistical methods were used, which are represented in using the simple and multiple regression method to estimate the functions of consumption, production, import and export of Egyptian fish, as well as food security coefficient in order to determine the most important variables that affect it by building an econometric model that explains the determinants of food security of fish. The double logarithmic model was the best model used in terms of economic logic and statistical significance, and Autoregressive and Integrated Moving Average (ARIMA) model was used to forecast production, consumption, imports and food security coefficients for fish until 2025. In addition to using the statistical method, One-way Anova- Analysis of Variance, to test the differences between a number of independent groups that represent problems that impede the continued increase in fish production, as well as the use of the least significant difference method (L.S.D) to arrange the elements of each problem. By estimating the growth rate of fish production and consumption, the fish food gap and the average per capita share, it was found that the growth rate of each of them took an increasing general trend during the study period, where the annual growth rate is estimated at 5.4%, 4.9%, 2.8%, and 2.7% for each of them, respectively. It was also found that the quantity of the surplus in fish attained about 0.9 thousand tons on average during the study period, and this surplus is very small, not enough consumption per day. It is also clear that the fish food security coefficient reached about 0.00073 on average during the period (20002018) and this indicates a decrease in the fish food security rate. The forecast values of the fish food security coefficient have shown that the fish food security coefficient tends to decrease from about 0.00076 in 2019 to about 0.00073 in 2025. And by studying the most important variables that affect fish food security in Egypt through the three basic functions, which are the fish demand function, the fish supply function, and the fish food security coefficient function, of the Simultaneous model, according to the economic logic and statistical significance, Increase in both national income (x13), imports of fish (Y3t), local production of fish (Y1t) by 1%, the food security coefficient of fish increases by 0.04%, 0.102%, 0.49% for each of them respectively, and when increasing Consumption (Y2t) by 1%, the fish food security coefficient decreases by 0.67%. This has proven the significance of the variables at the level of significance 0.01, as it turns out that by increasing exports (Y4t) by 1%, the food security coefficient decreases by 0.01% and this decrease is statistically significant at the  level of significance 0.05. A stratified random sample was chosen according to the cognitive and functional level, with the problems and obstacles of continuation of increasing fish production in Egypt. The sample was of those interested in the field of fish wealth. The problems were identified and divided into five categories which are: environmental problems, financing and production problems, marketing problems, problems related to scientific research, administrative problems. The study resulted in several recommendations, the most important of which are: Increasing the expansion of culture operations in floating marine cages. Increasing investment orientation for fish production from its various sources and providing financial support to small fish producers. Close control of the various pollution image processes of natural resources, overfishing, offensive fishing, and fishing fry and limiting their spread to preserve biological stocks.
