Looks at the future of cotton in the world by forecasting its progress during the period (2009-2018), the direction of the Beginning stock to decline during the same period, while that the harvested area and end stock consumption relatively stable during the same Period, while exports and imports tended to increase during the same period, As for the forecasting of the Egyptian market during the same period the harvested area has tended to decline while increasing domestic consumption and with the relative stability in the beginning stock, as well as exports, Comparing the results to predict the global and Egyptian variables is showed Egyptian market for cotton towards the import of foreign cotton.

The recent study aims to: identify the degree of farmers implementations for the recommendations of the technical rationalization of water use in New valley Governorate. In addition, identifying the independent variables affecting the degree of farmers implementations for the recommendations of the technical rationalization of water use as a dependent variable. In order to accomplish the study objectives, new valley Governorate was selected as a filed study. A systematic random sample of 212 farmers was selected. This sample represents about 5% of the total farmers in three villages in New valley Governorate. A questionnaire was designed and collected using the personal interview (after it was pre tested) during may 2011. Then, the data were tabulated and analyzed by using simple correlation coefficient, stepwise regression. The study finding showed that about 14% of the total sample have low level of implementations for the recommendations of the technical rationalization of water use. Medium category represents about 50%, and high category of implementations for the recommendations of the technical rationalization of water use represents about 36% of the total sample. Results revealed by using stepwise regression showed that three variables affected the degree of implementations for the recommendations of the technical rationalizations of water use, and these variables explained about 51% of the total variance of the implementations for the recommendations of the technical rationalization of water use. Those variables were: farmland holding size, respondent attitude towards the extension activities, finally respondent degree of formal social participation.

This paper aimed to examine the impact of climate change on wheat productivity in the five rains- fed districts: El-Negaila, Sidi Barrani, El-Daba'a, Marsa Matrouh, and EL-Alamain in the northern west coast of Egypt in which the cultivated wheat area represents about 41.4% of wheat area in Matrouh Governorate (1990-2019). The productivity is fluctuated between 1.167 to 13.38 Ardab/Fadden accompanied with the fluctuation in precipitation between 24.35 to 115.10 MM3/Season, and fluctuation of average difference between Max. Min. temperature from 8.07 to 7 ºC. Fully Modified Ordinary Least Square (FMOLS) technique was applied to investigate the relationship between wheat productivity and the independent variables (precipitation, temperature, cultivated area, labor and technology). OLS function showed that the model suffers from endogenity and heteroscedasticity. LLC and IPS statistics of panel unit root test proved that the included variables have unit root, i.e. they are non-stationary at level. Pedroni panel residual cointegration test confirmed the long run relationship between the first-order integrated variables [I (1)]. FMOLS function proved that natural climatic variables are the main determinants of wheat productivity, as a 1% increase in annual rainfall improves wheat productivity significantly by 3.3%, while temperature affects the wheat productivity negatively by 5.7%. The far west districts are the most affected by rainfall, as 1% increase of rainfall in EL-Negaila and Sidi- Barrani districts increase wheat productivity by 8.4%, 5.1% respectively. Results in all districts except EL-Negaila and Sidi Barrani showed the extent of labor intensification to enhance productivity, also all districts showed the importance of technical improvements. It is recommend adopting water policy as rain harvesting, building stone dykes and cisterns to provide: 355.5, 301.7, 287.9, 339.8, and 245.8 MM3/Fadden in El-Negaila, Sidi Barrani, EL-Daba'a, Marsa Matrouh, and EL-Alamain districts respectively to improve wheat yield to 12 Ardab/Fadden under drought climate of north coast

The research aimed to measuring the Efficiency of the Agricultural Economic Resources Used in Summer Tomato Production in Alexandria Governorate, the research is relied on using of some descriptive and quantitative economic analysis methods in data analysis, especially Data Envelopment Analysis (DEA) method, based on field data collected during the 2020 season from 30 summer tomato's farmers in Alexandria Governorate. The research reached a set of results, the most important of which can be reviewed as follows: (1) The overall efficiency criteria for a feddan of summer tomatoes in the research sample are: the net return is about 12.52 thousand pounds, the income over variable costs is about 17 thousand pounds, the benefitcosts ratio is about 1.41, and the profit of the spent pound is about 0.41 pounds. (2) The average Scale Efficiency was about 95.6%, which means that the percentage of exploitation of economic resources used in production in summer tomato farms in the research sample was about 95.6%, indicating that there is a possibility of expansion of 4.4% to reach the optimum volume of production on these farms. (3) The average Technical Efficiency according to the (BCC) model is about 98.4%, and this confirms the possibility of increasing the summer tomato production by 1.6% without increasing the amount of economic resources used. (4) Inefficient farms can achieve complete technical efficiency as reference farms by reducing the economic resources used, which are: the human labor by 7.22%, the automated work hours by 8.36%, the seedlings by 2%, the fertilizer Municipal by 4.62%, nitrogen fertilizer by 4.39%, phosphate fertilizer by 4.96%, potassium fertilizer by 4.93%, and pesticides by 6.81%, while keeping the same volume of production of summer tomatoes research sample. (5) The average Allocative Efficiency of summer tomato farms was about 79.7%, which means that re-employing the used economic resources will save about 20.3% of the production cost through adopting better technology and optimal employment of resources. (6) The average Cost-Efficiency of summer tomato farms in the research sample was about 78.4%, which means that production costs can be reduced by about 21.6% of the current production costs without affecting the production level of summer tomatoes. (7) Achieving the technical efficiency of summer tomato production at the level of Alexandria Governorate the following: (a) Increasing production by 13.07 tons, with a monetary value estimated at 23.59 milliom pounds, (b) providing an area of agricultural land with a horizontal expansion of 586.12 feddans, which is equivalent to the increase achieved In production as a result of raising technical efficiency, (c) rationalizing the use of irrigation water in Alexandria, with a total of about 2.04 million m3 , which is the amount of savings achieved in irrigation water that is necessary for the area of land that has been provided in Alexandria. In light of the findings of the research, it recommends the necessity; (1) Educating summer tomato farmers about the optimal the economic resources used in production to reach the optimum volume of production, (2) Reduce the prices of agricultural production inputs and provide them in a timely manner so that the farmer does not resort to the black market, (3) Issuing advisory bulletins to confront the changing climate and high temperatures in summer tomato cultivation.

The current study aims to: 1) identify role's perceptions, expectations and behavior within the family from gender perspective in the study area, 2) identify the differences of perceived, expected practice roles of men and women in rural family, 3) identify the interrelationships between role of gender in rural family and 4) identify factors influencing role perceptions, expectations and behaviors from a gender perspective in rural families. Data were collected from a sample of 110 families in the village of Palestine in the El-Kharga district in The New Valley Governorate using a questionnaire form prepared to achieve the objectives of the study. Data were collected during October and November 2016. The frequencies, percentages, mean, Pearson's simple correlation coefficient, and (T) test in the presentation and analysis of results. Findings revealed that the relative weight of men's 'perceptions of their role in the household reached 77.88% while the relative weight of women's perceptions of their roles reached 73.03%. 96.36% and 69.09% for role expectations while 71.15% and 68.79% for role behavior of men and women in rural family. The results also indicate significant differences between men and women with regard to perceptions, expectations and behaviors of the social role within the rural family. The results also indicate that there are 11 significant correlations between the levels of the role according to the gender in the rural family. Regarding the factors affecting role perceptions, expectations and behaviors within the family, the results indicate a significant correlation between the type of family as an independent variable with the role perceptions and behaviors of women, the number of family members and the expected role of women, the number of female and role expectations of women in the family. Regarding the social role of men, the results indicate the significance of the correlation between the wives' work status and participation in family expenditure as independent variables with the role perceptions and behavior of the of men within the family.

The purpose of this study was to 1) assess the linkages in the New Valley’s Agricultural Innovation System (NVAIS) and 2) characterize the information structure underlying the system. Data were collected from 50 respondents represent the nine components of the studied system during the period from Feb. to Mar. 2015 using in-depth interviews. The graph theoretical technique (GTT) was used to assess the linkages and information structures in the studied system. The obtained results showed that NVAIS was not fully identified; however, 44 of a total 72 linkages only were identified, and have a density of 0.61. Only 14 linkages are established through specific linkage mechanisms so density declines to 0.19. The component "Observatory of Development and cooperatives (O)" is by far the main sender of information, followed by the component "Extension (E)" and "Higher Education (H)". The main receivers of information, is the component of "Farmers (F)". Components of "Research (R)" and "Policy (P)" have a special position in this system, being the most interactive components as it sends as much information as it receives from others. Components of Secondary agricultural schools (S) and Agricultural Credit (C) are candidates to reform because of they interacts other components at a low tone. The component of private input supply, marketing and processing (M) is isolated is needs to deal efforts on enhancing its interaction within other components of the system. Any interventions on the components of O or F will be reflected in all over the system because the first one is a dominant component while the second is subordinate. The intermediary institutions, O and E, should play a more active role in bringing together other components. Specifically, links between these components could be strengthened through policy dialogues where the O and E could pass information from S, F, M, and C to P, H and R; such transmission of information should help P, R and H reassess agricultural policy, research and education priorities
