Its role is great in ensuring the country's food security, improving the balance of payments and strengthening state independence. The state and proportions of development of other sectors of the national economy depend on the level and speed of development of agricultural production. This connection is reflected in both technical-technological and industrial-economic connections. At the same time, this connection is bilateral, with the increase of agricultural production, the structure and quality of food of the population improves, the volume of imported food decreases, which has a positive impact on reducing the balance of payments deficit and increasing the degree of independence of the country.\u0000Due to the important role of agriculture, the field received a lot of attention in the first years of the restoration of independence, which is confirmed by the agrarian policy developed and implemented during that period, whose primary task was to ensure the country's food security and strengthen food independence. In connection with the important role of agriculture in the first years of the restoration of independence of the region, much attention was paid, which is confirmed by the agricultural policy developed and implemented during this period, the main task of which was to ensure the country's food security and strengthen food independence. At the same time, it was a great challenge for a country with a devastated economy, followed by significant reforms in agriculture, restructuring of the sector and the creation of an appropriate legal framework, the integration of state regulation of the market economy and self-regulatory mechanisms. However, under the influence of a number of external and internal factors, it was not possible to fully implement the developed agrarian policy. Agriculture is still characterized by low productivity and, consequently, by a small share in the sectoral structure of the national economy. The country has serious problems in supplying and providing vital agricultural products such as wheat, corn, potatoes, vegetables, meat and poultry.\u0000The global pandemic and the resulting global economic crisis have put the issue of solving the country’s food security problem on the agenda. To this end, the revitalization of rural areas, social stability and balancing the level of migration from rural to urban areas should be a priority. Establishing food security is a complex task and is primarily the responsibility of the government. There is no universal mechanism for solving the global food security problem in the world today. This problem must be solved at the national level, as food security is considered to be a level of national food production that allows the principle of self-sufficiency of the population and state reserves with food to be implemented in accordance with scientifically substantiated norms.

To satisfy expected increases in agricultural products within traditional methods becomes more and more difficult, considering the climate change and soil degradation. There is a need to adopt and develop innovative agricultural practices. One of the most effective and new methods that can be used is Aeroponics. Aeroponics is a process of growing plants, within a controlled environment, in the absence of soil, with a small amount of water, using a minimum area of 3-dimensional greenhouse farming, where the cultivation period, compared to the traditional, is faster and prolonged throughout the year. Regarding this matter, we find it reassuring, that Georgian companies are not lagging behind the current global processes and are actively involved in refining or developing the Aeroponics system.\u0000The advantages of Aeroponics over the traditional method (Geoponics) can be classified as follows: \u0000• Requires less water. \u0000• Plant fertility does not depend on soil quality, or weather conditions. moreover, soil is not required at any stage of plant vegetation. \u0000• Has the highest vegetation per square meter compared to all other existing methods (Geoponics, Hydroponics), which is due to the possibility of 3-dimensional farming in Aeroponics. \u0000• Reduces transportation cost, since greenhouses can be organized directly in the cities and in urban areas. \u0000• The plans can be planted all year round regardless of meteorological conditions and seasonality. \u0000• Since nutrients and minerals are systematically provided to the plants’ roots, the process of its growth and consequently fertility lasts longer than the traditional method.\u0000As for disadvantages of using Aeroponics can be summarize as following: \u0000• At the beginning stage, set up costs of all components for the Aeroponics are relatively high. \u0000• Aeroponics requires specialized knowledge not only regarding the needs for plants, but also of the whole electronic systems and tools, which are widely used in Aeronautics (for example: pH / EC / humidity meter, timers, high pressure atomizers, etc.) \u0000• Even minor mistakes can have negative effect. Specifically, if the plants do not get exactly as many vital minerals as needed, they will not survive. As already mentioned, soil is not used in Aeronautics which would neutralize excess minerals or nutrients. \u0000In conclusion, Aeroponics is the one of the most innovative and efficient ways of farming, which promises sustainable future production of the agricultural products. Furthermore, Aeroponics has minimal or no negative impact on the environment, while traditional farming uses water and land resources insufficiently.","PeriodicalId":344544,"journal":{"name":"Economic Profile","volume":"216 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133939630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This allows them to predict the results of the investment project implementation and to make final conclusions about the effectiveness of the investment project compared to the actual indicators. Moreover, there is a clear tendency to reduce the volume of projects for which pre-selection-evaluation procedures are applied, before making a decision on their implementation.\u0000On the example of Georgia, despite the fact that a normative base for pre-selection and evaluation of investment projects has been created with the involvement of donor organizations, we have not been able to find even one case of selection and evaluation of investment projects at the municipal level (except the capital).\u0000Therefore, the aim of our research is to identify the circumstances that prevent municipalities from pre-evaluating investment projects, analyze the challenges municipal authorities faces in this area, make appropriate conclusions and develop recommendations to solve the existing challenges.\u0000There was approved \"Investment Project Management Guide\" by the Government Resolution №191 on the management of public investment projects (22.04.2016); The management methodology of investment project was approved y the order of the Minister of Finance of Georgia N165 (22.07.2016) and according to them, public investment projects with a value of 5 million GEL or more were subject to selection and evaluation.\u0000According to the international practice, the above-mentioned guide and methodology suggests the use of CBA - Cost-Benefit Analysis and CEA - Cost-Effectiveness Analysis methods for the evaluation of alternative projects.\u0000Cost-benefit analysis in the evaluation of a public investment project is characterized by certain specific features, which is reflected in the fact that the evaluation of costs and benefits of the investment project goes beyond the narrow spectrum of financial indicators of the implementing agency and is done in a broader economic context. It is called as economic cost-benefit, which refers to the estimation of costs and benefits in the context of society as a whole, including possibly costs and benefits for which market prices are sometimes not directly observable.\u0000Therefore, in order to evaluate investment projects with this approach, it is necessary to have a number of statistical data and information in the target area of the project, depending on the specifics of the project, which in most cases are impossible to obtain at the municipal level. Therefore, they are not able to use the cost-benefit approach when evaluating alternative projects. However, as our observations have shown, this is not the only reason and there are other interceptive conditions. \u0000In that case when it is not possible to calculate the benefits of project implementation with sufficient accuracy, it is advisable to use","PeriodicalId":344544,"journal":{"name":"Economic Profile","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130711018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Other businesses have a very close relation with this business and therefore they have been affected as well. As you know, the world travel and tourism market is expected to have lost more than 75.2 million jobs by 2020. According to the UNWTO, small and medium-sized enterprises were most affected. Their share in the tourism sector is 80%. Coronavirus will have a special impact on the countries whose economy accounts for a large share of tourism and whose economic growth is largely due to the tourism sector, and Georgia is also among them.\u0000 According to the Georgian government, Georgia will develop the tourism sector in the near future, of course, in compliance with the safety standard and taking into account the recommendations. Tourism is the sector that has received the hardest and first blow due to the crisis and which, in addition to being one of the most important driving forces of the country's economy in recent years, the sector has a competitive advantage that can contribute to the economic development of Georgia in the post-crisis pandemic economy.\u0000 Tourism is one of the largest spheres in the world, and its development is conditioned by the safe environment of the country, economic and political stability. It creates jobs and helps increase incomes for the population. International tourism contributes to the inflow of foreign currency into the country and affects the social and cultural environment of the country. That is why it is important to bring the tourism business out of the crisis.","PeriodicalId":344544,"journal":{"name":"Economic Profile","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123906118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Almost the whole world is facing very serious obstacles on the international and national levels. Too many problems emerged in the world countries. To resist against the new disease has become the main priority for each country. \u0000The global processes caused by the pandemics have influenced the audit service as well. The uncertainty and unpredictability caused the new risks of deficiencies and activated already existed ones in the new environment. The situation became more complicated due to the fact that it can happen that the auditors do not consider the mentioned risks in the process of planning for audits or the risks may be considered mistakenly. \u0000The firms and other economical institutions in which the audit is carried out are obliged to adopt the new rules and changing environments in which their businesses function; they should change the rules of fulfilling the operation, preparing the financial accounts, the processes of their representing the information processes, safety of information shown in the financial accounts, the rules of their preparing; they also evaluate the possibilities of keeping on their activities in the nearest future. \u0000The qualified performing of the audit implies the basical elemenst which helps to create such environment where the possibility of the high level audit will be at the maximum. \u0000Implementing the quality control implies that such system will include two stages; each of them is directed towards providing the audit processes according the international standards \u0000There are several types of the quality improvement system.

At the same time, according to the results of 2019, food imports exceeded exports by 3 times.\u0000Many factors need to be considered when formulating a state support policy, however, the strategy for action should be based on several important principles:\u00001.
