Project summary

The aim of the project is to prevent global warming of the atmosphere by utilization of excess carbon dioxide via natural biological ways.

Other aim of the project is receiving high effective starch-contained food for animal husbandry.

The problem of global warming is one of the main problems that mankind is faced with. Without solving this problem there is no prospects for present civilization to develop in future. It is a problem of technogenic type and is connected with the phenomenon of the greenhouse effect. It is caused by infringement of natural balance of concentration of carbon dioxide in the atmosphere. CO2 is notable for its ability to let pass ultra-violet radiation but absorbs infra-red one. Increase of its concentration in atmosphere will lead to decrease of stream of energy, radiated by the Earth in space in infrared range that will be followed by the growth of average annual temperature on the Earth.

The results of the measurement, which has been carried out by the stations of background air pollution monitoring organization, have shown that in conditions of existing growth of the excess concentration of CO2 in the atmosphere in the nearest future will bring to growing of average annual temperature in 1,5 – 4,5 0C. Calculations have shown that as such growth of temperature will cause intensive thawing of ice and the level of World Ocean will rise on the average on 60 meters. This equals to global flood and big part of land will appear under the water in near future.

For now the various arrangement has been taken to reduce growing of CO2 concentration or to keep it even on the present level. However, those methods all are technically and technologically very difficult, economically very expensive and do not have desired results.

Carbon dioxide (CO2) is permanently absorbed during the photosynthesis by the green plants. Its concentration in the different regions of the earth is almost the same because of processes of turbulent mixing and diffusion taking place in the atmosphere.

It is advisable to use wild green plants for utilization of excess of carbon dioxide.

The objective of the project is achieved by the fact that as utilizers of CO2 are used green plants that absorb it in a big amount and supply as a starch. As previous researches have shown this kind of plants for Georgia can be the following: squirting cucumber (Ecballium elaterium (L.) A. Rich), Acantus (Acantateae), Persimmon (Diospiros), citrus (Citrus Lin.) etc. Especially effective is squirting cucumber. About its advantages shows the fact that it gives 100 tones green masse and 100 tones root crops per hectare during year. To the plants, containing starch, belongs also wheat and rice but productivity of wheat is 15 tones per hectare, and productivity of rise – only 3 tones per hectare.

Scientific value of the project is the fact that during the implementation of the project the following will be studied:

  1. Population structure of the Tbilisi variation of the squirting cucumber and their potential opportunity of utilization СО2 in vegetative mass in root crops and in green parts of the plants.
  2. Features of crossingover in condition of excess СО2 in the air.
  3. Utilization of the СО2 in green mass and in root crops depending on the seasons (in Autumn, in Spring, in Summer).
  4. A limiting doze of absorption of СО2 in green mass of plants.
  5. Quantity of the radiation energy that is necessary for transformation monosaccharides into starch and the last into the monosaccharide.
  6. Types of bacteria that live together with squirting cucumber and their auxiliary role in utilization of СО2 in starch and deutilization of starch into monosaccharide.

New and distinguishing feature of the project represents the fact that as a result of generalization of the results for each zone of the earth there will be found plants with long vegetation, having big vegetative mass and absorbing CO2 in a maximum amount.

It is difficult to assess economic benefits of the project as insignificant economic expenditures will prevent disastrous effects of the greenhouse effect and at the same time big amount of high-effective starch-contained and natural food will be available for cattle breeding

From humane point of view the significance of financing of the project is difficult to revalue. On the one hand this will be welfare for the involved in this project forcedly moved specialists of the GIK who live in hard economic conditions. On the other hand this is especially important as based on the results it will be possible to decrease concentration of CO2 and keep it even on the present level.
