An Economic Study about the Efficiency of Using Water Resources to Produce some Agricultural Crops
(Case Study in Gharbia Governorate)
|
|
Abstract: Summary:
This study aimed to studying the economic efficiency of using the available water resources in producing some agricultural crops and trying to reach the maximum possible return in light of the available resources in the presence of a clear waste in the use of irrigation water in Egypt in general and in the middle of the delta in particular as a result of adopting the method of flooding irrigation, which leads to a high level Ground water, blockage of drains, and loss of fertilizer residual crops with wastewater, leading to deterioration of acre productivity, as well as a decrease in per capita food share.
This study consists of three main chapters beside the introduction which includes; study problem, study goal, research method, data sources, and contents of this study. Chapter One includes clarify for some definitions which are found in the study and referential review for some previous studies relevant to the subject of the study.
Chapter Two contains studying of Study the current situation of water resources and the efficiency of irrigation water management according to the different irrigation sources in Gharbia Governorate, while Chapter Three
The results showed the following:
1- Fresh water in Gharbia Governorate during the study period decreased by 42.15%, and the average irrigation water needs are increasing by about 9.5%.
2- It was found that the average actual consumption of irrigation for wheat and rice in the center of Al-Mahalla Al-Kubra exceeds the water quotient allocated for irrigation of wheat and rice acres at a rate of change of about 62.45%, 27.9%, respectively, while the average actual consumption of water for irrigation of wheat and rice in the Zifta center exceeds more than The water rated for irrigation of wheat and rice acres at a rate of change of about 78.4% and 42.0%, respectively.
3- The average total costs of wheat acre production that was irrigated using both canal water, groundwater and mixture water in the Mahalla al-Kubra center is higher than the average costs of wheat acre production in the Zifta center by about 4.89%, 3.15%, and 5.94% each of them respectively, The average total costs of producing an acre of rice that was irrigated using both canal water, groundwater and mixture water in the Mahalla El-Kubra center is 17.72%, 15.14%, and 6.74% each of them respectively.
5- The total return to the total costs in the wheat crop that was irrigated using canal water in the two central Mahalla and Zifta areas reached its highest value compared to other irrigation sources as it reached about 1.65, 1.71 for both centers respectively, and the return of the pound invested in the production of wheat acres that was Irrigation using canal water the highest value by 0.651 and 0.707 pounds, respectively, The total return to the total costs in the rice crop that was irrigated using canal water in the two central Mahalla and the Zifta center reached its highest value compared to other irrigation sources as it reached about 1.76, 1.87 for both centers respectively, and the return of the pound invested in the production of rice acres that was Irrigation using canal water the highest value by 0.756 and 0.873 pounds, respectively.
Chapter three contains four chapters dealing with the standard assessment of the impact of the most important economic factors on the amount of output from the study crops and to identify the most important problems of different irrigation sources and proposals for solutions. By studying the semantic relationship between the quantity of the output of wheat crop irrigated with canal water, groundwater and mixture water as a dependent variable, and some productive factors as interpreted variables, it was found that the most important factors with a positive effect on the amount of wheat output are the factor in the number of human work hours, and the amount Seed, and the amount of phosphate fertilizer, while the effect of the water element was negative, which indicates the existence of wastefulness in this resource. For rice crop irrigated with canal water, groundwater and mixture water, it was found that the most important factors that have a positive effect on the amount of wheat output is the element of the quantity of used seeds, and the amount of nitrate fertilizer, while the effect of the amount of irrigation water is negative, which means that there is excessive use of this Element.
