“…The most promising technology is the cultivation of rice using drip irrigation. This is confirmed by more than ten years of successful experience in the cultivation of rice with drip irrigation in China [15], as well as domestic developments of technologies for cultivation of rice with drip irrigation, which have been successfully tested in the farms of the Volgograd and Rostov regions [16][17][18][19], and have proven the effectiveness and feasibility further research in this direction. The effectiveness of drip irrigation is due to a number of factors [20]: a reduction in the irrigation rate, the possibility of rice cultivation on the lands of non-irrigation fund, the development of fundamentally new rice crop rotations with the inclusion of melons and vegetables in them.…”

The domestic and foreign research in the field of rice cultivation carried out over the past 10-15 years has identified four main promising technologies that can reduce the cost of rice produced: 1 - intermittent flooding; 2 - periodic moistening without creating a layer of water; 3 - sprinkling, including surface irrigation; 4 - drip irrigation. Drip irrigation of rice is the most priority area of research, since it can significantly reduce the irrigation rate, labor costs, the cost of rice production and anthropogenic load. The purpose of our research was to develop a new technology of rice cultivation with drip irrigation adapted for the climatic and soil conditions of the Krasnodar Territory. As a result of the research carried out, a drip irrigation technological scheme was developed and implemented for LLC “Chernoerkovskoye” of the Slavyansky District of the Krasnodar Territory. The developed scheme of rice cultivation on drip irrigation has proven its effectiveness, which was expressed in improving the reclamation state of soils, increasing the profitability of production by 22% and increasing the yield by 20%, reducing the irrigation rate by an average of 5.3 times, the cost of rice grain by 15% and labor intensity by 34%.

According to the studies carried out by the US Geological Survey (USGS) under the project GFSAD30, Russia ranks fourth in the world in the number of fertile lands. However, today there are some problems that “slow down” the development of the Russia’s agricultural sector, including the rice-planting complex. One of the main problems of the Russian agro-industrial complex is unsustainable environmental management, which leads to inefficiency and sometimes loss of agricultural production. This is caused by the “rigidity” of the legal framework, the reluctance or inability of the economy to switch to new resourcesaving technologies, as well as the fear of partially or completely losing the crop when switching to new technologies. For the “soft” transition of the economy to new resource-saving technologies, we propose a resource-saving technology for cultivating rice on underground drip irrigation under mulch film on rice irrigation systems, the introduction of which proved its effectiveness, as well as the relevance of our study. The efficiency of proposed resource-saving technology of rice cultivation on drip irrigation is expressed in the increase of profitability of rice production by 26%, reduction of irrigation norm by more than 5 times, labor intensity of rice production by 42% and material costs by 24%. The proposed technology not only reduced the anthropogenic load, but also improved the land reclamation condition, including the situation in the rice irrigation ecosystem. Further development of drip technologies in the rice sector of Russia will allow developing fundamentally new, ecological-reclamative, balanced rice crop rotation with the inclusion of vegetable and cucurbits crops. The proposed technology will provide an opportunity to cultivate rice outside rice irrigation systems on previously rich lands, which will give agro-industrial workers new opportunities and prospects in rice production.

“…The principal factor of profitable investment of capital is knowledge of the specifics of the implementation of specific investment projects and the use of effective innovative methods for calculating the effectiveness of planned activities [8]. The most general relationship between the probability of risk and the predicted return of an investor is reflected by a pattern: the higher the return on investment, the higher the risk of not achieving it; reducing the return increases the probability of no risk of investment [9].…”

The purpose of the study is to improve methods for improving the regulatory and methodological framework for assessing the environmental and economic effectiveness of land reclamation investment projects. The research methodology is based on the Monte Carlo method, which corresponds to international standards, the theory and algorithms of innovative methods for determining risks, as well as the ability to provide the user with information about the content of risk assessment operations and ensure that their preferences are taken into account in the calculation process. Currently, many tools have been developed for automating risk analysis procedures, including those performed by the Monte Carlo method, which are described in various studies with varying degrees of completeness. The analysis of priority methods of assessing the risks of achieving the projected economic indicators of project solutions is performed and the prospects of the simulation method for practical use in the field of land reclamation are shown. The results of the risk assessment of environmental and economic efficiency of anti-filtration coatings of hydraulic structures of irrigation systems performed by the Monte Carlo method in the environment of the Crystal Ball software product are presented, and the need to improve the reliability of the predicted results of the effectiveness of the designed measures is established. Future research is risk assessment of profitability of the designed activities promote the development of existing and formation of new theories to justify the feasibility of implementation of reclamation investment projects.
