Abstract:

Drought is one of the major problems that Kerman province is facing. And in the last decade, it has gained critical dimensions. The resulting data tables were developed both as a theoretical framework and as a practical economic tool. And in addition to its analytical and practical dimension, it is considered a strong and coherent statistical framework both in terms of statistical coordination and in terms of harmonizing definitions and concepts. In this research, the researcher sought to answer these questions using the data table.

Which sub-section is the key part of the agricultural sector? Does the forest production sub-sector have the lowest water efficiency among agricultural sectors, and what is the effect of importing intermediate inputs and final products with regard to virtual water on improving water efficiency?

The results of the research indicate that the largest share of water in the intermediary cost is related to the activity of the agricultural sector and the agriculture and horticulture sub-sector, and the lowest is related to the service sector and the restaurant sub-sector. Also, the highest added value created per one million rials of water is related to the service sector and the restaurant sub-sector, and the lowest is related to the activity of the agricultural sector and the agriculture and horticulture sub-sector. According to the rank of the sub-sectors in the previous and previous links and also their rank in productivity, the fishing sub-sector was determined as the key sub-sector of the agricultural sector. And the sub-sectors of agriculture increased productivity in water consumption by importing virtual water.

Especially in Kerman province, which covers a large area of ??dry and desert areas. Due to the recent droughts, the importance of water as a yard input has already been determined. (Mirzaei, 2016) The analysis of water consumption in the agricultural sector is very important due to the position of Kerman province, and a large area of ??it is dry and desert areas. In the agricultural sector, a large amount of water is supplied through wells. And it is given to the farmer, who has no control over how to use it. Does the farmer have full respect for the amount of water he uses?

In Kerman province, he has lost fresh and underground water table­ is Today, in Kerman province, the development of one meter of agriculture has no rational and technical justification. Excessive consumption of water in the agricultural sector and not using modern technology and irrigation is one of the causes of the current situation. Due to the low tariff and the uneconomical price of water, we have competed with each other in destroying water resources in all sectors, and day by day we are taking steps to make water resources worse. And a solution should be found for this alarming water situation in Kerman province.

Using modern agricultural methods and optimal use of water are vital factors to achieve the goal of providing food for the growing population of the world. According to estimates, in the next 30 years, the world's people will need 60% more food. A significant part of this increase in production will be the result of intensive cultivation (using less land for more production) that requires irrigation. One of the main and limiting factors in the development of Iran's agricultural sector is water input. And if there was no water restriction, 30 to 50 million hectares of the country's lands could be cultivated. (Mirzaei, 2016)

Due to the special power of data analysis, the resulting data tables have been increasingly used in economic planning day by day. Among the factors that led to the use of this technique are:

Due to the existence of inter-sectoral relations in a wide group of economic sectors, the resulting data tables have good strength and internal powers. Since these relations in the output data table can be controlled with several figures, its reliability is very high. And on the other hand, constant and strategic technical coefficients in a period make this internal structure stronger.(Farmani, 1390)

The uniqueness of the answers obtained from solving the obtained data models is one of the advantages, which makes this method preferable compared to econometric equations. And this feature is caused by the cross-sectional nature of the output data compared to the time series information of econometric relationships. (Farmani, 1390)

In the data table, the statistics of the economic variables show the whole economy in a logical order. It also shows inter-departmental communication in all departments. And it does not assume any of the parts as fixed, or leave them aside. (Farmani, 1390)

One of the other advantages of data analysis is to show how the process of structural changes in the entire economy and production technology. This part of the data acquisition technique is used for studying structural changes. (Farmani, 1390)

In this research, taking into account the inter-sectoral relationships in the data table of Kerman province, the experiment and analysis of water consumption was carried out. It has been, and compared to the average rainfall in the country which is about 250 mm, it is less. (Mahmoudi et al.) Actually, these numbers are before the drought, which happened. There is almost 14 years of drought. And unfortunately, the blue year 90-91 was in the worst condition. Most of the rainfall was in Bahman and March. No matter how short the rainfall period is, it will cause the seasonal rivers to flow and flood. If there was a situation where rainfall occurs over time, this rainfall will be more absorbed by the underground aquifers. The year 1990-1991 was a very bad year in terms of rainfall, with 100 mm of rain in a short period of time. Even if we consider the average rainfall of 140 mm, which is the report of the study unit, the volume of annual precipitation is 25 billion cubic meters, of which 18 billion cubic meters evaporate due to the vastness, hot, dry, and desert nature of the province. 1.4 billion cubic meters is in the form of running water and 3.85 billion cubic meters is direct absorption of underground water tables and 1.75 billion cubic meters is indirect absorption. And the sum total of direct and indirect absorption is 5.6 billion cubic meters. Unfortunately, the extraction from underground water tables is 6.7 billion cubic meters. That is, 14 years ago, the negative water balance of the province was 1.1 billion cubic meters. (Kerman Regional Water Company, 2013) Water wastage in Iran is more than the world average. And according to the available reports, the rate of water wastage in our country is 28-30%, while this amount is reported as 9-12% in the world, one of the main factors of which is unauthorized withdrawals from the water supply network and wear and tear of water facilities and water supply networks. Reforming the consumption pattern is the only way to overcome the crisis of water shortage, considering the traditionality of agriculture in the country and also the reduction of water resources, reforming the consumption pattern in different sectors seems to be the most suitable and logical solution to overcome the existing crisis.
