At present time, the significant deficiency of СО2 for plants cultivated in greenhouses is one of the factors limiting the photosynthesis and carbonate accumulation leading to decrement of vegetable plant productivity.  The development of necessary gas atmosphere inside greenhouses is the same as important as maintaining temperature regimes.  In  the  world,  there  are  different  solutions  for greenhouse feeding with СО2. Nowadays, the most effective and ecologically safe equipment for greenhouse feeding with СО2 is that provide, not only a smoke-like gas, but also a purified food quality carbon dioxide. This technology required system of gas pipe lines for greenhouses and system of automated control for gas feeding. Moreover it is necessary to install the storage facilities for liquid  carbonic  acid, gas generator, heating system and other   equipment.   Such   a   complex   for   automatic greenhouse feeding with СО2 ‘Kaskad’ has been worked out by OOO ‘Kaskad’ that has successfully developed the systems for carbon-dioxide feeding for 10 years. The system  that  combined  automatic  supplying  outcoming  gas from  boiler  station,  and liquid  СО2  injecting  into  greenhouse room was developed in 2015. The system enables to be integrated into the feeding liquid СО2 and existing system of supplying the outcoming  gas from boiling station.

Relevance. Agroforestry systems are believed to provide a multitude of ecological services. It is thought that agroforestry enhances resilience to the impacts of climate change and aids in adaptation by supporting diverse land use practices, sustainable lifestyles, and income streams, as well as increasing productivity in both forests and agriculture, and reducing weather-related losses in production.Results and Discussion. The aim of this review was to present genuine evidence on the role of agroforestry in ecosystem conservation and mitigation of climate change impacts. Compared to monocropping and open cereal-based agriculture, agroforestry has made a more significant contribution to ecosystem conservation and in reducing carbon dioxide emissions. However, it has been found that agroforestry contributes less to carbon sequestration than natural forests. Carbon sequestration through above-ground and underground biomass, carbon emission reduction from deforestation, and microclimate adjustment are key measures for mitigating climate change. Agroforestry systems provide essential ecosystem services, such as food, fuel wood, fodder, income, and improved soil production, which enable communities to cope better with the impacts of climate change. Therefore, agroforestry must be given significant attention if it is to play a crucial role in ecosystem management.
