Purpose: freezing and temperature stabilization of soils of dams, wellheads and other structures up to 100 m deep in order to ensure their operational reliability. Seasonally acting cooling device is a hermetically sealed, fixed welded structure filled with coolant. The depth of an underground part is more than 13 m, there is also a ground part of the structure.
Forced air blowing of finned tubes allows during the most frosty windless periods to significantly increase the heat exchange and get the temperature of freezing pipes is almost equal to the outside air temperature. Such a system is designed for intensive initial freezing and further economical maintenance of the resulting frozen ground zone.
Carbon dioxide is an ideal coolant for deep-seated seasonally acting cooling devices, it fills the entire freezing height of cooling devices, and intensive circulation of coolant is provided by the use of special internal devices. Collector seasonally acting cooling devices with air cooling units have a place of application, such as in Yakutia, with the typical windlessness of this region. The project can be implemented at large industrial facilities.
Exploring best practices in infrastructure adaptation to climate change
Infrastructure adaptation is one of the priorities of the climate change work. For instance, 65% of the region's infrastructure worth US $10.93 billion is expected to be damaged or destroyed by 2050 in the Republic of Sakha (Yakutia) alone. In this regard, one of the priority areas of the Fund's research becomes a study of best practices in infrastructure adaptation.
1. Identification of key infrastructure, areas, and landscapes in the Russian Federation in need of pilot projects to protect against climate change.
2. Research of existing international practices (USA, Canada, Norway, China) and Russian regional practices.
3. Developing a theory and a base of best practices for adapting infrastructure for implementation on the territory of the Russian Federation.
4. Conducting expert verification of the theory with international experts engaged in infrastructure adaptation projects (Dmitry Streletsky, Sean MacDonald).
5. Presentation of a study and publication of an online resource with an interactive map of possible solutions for infrastructure adaptation to permafrost.
Research of climate change impact on local populations
According to the United Nations, it is the indigenous peoples living within the permafrost area are the most affected by climate change, so one of the research priorities is to conduct a study on the current state of indigenous peoples' habitats, to develop projections of the effects of climate change on these areas, and to propose ways to prepare for these changes.
1. Analysis of existing international research, academic literature and best practices on Climate change in the Arctic: impact on indigenous groups
2. Analysis of existing studies in Russia,
3. Research into the key factors affecting the lives of indigenous peoples in one or more of the regions of Sakha (Yakutia), Yamal-Nenets Autonomous Area, or Khanty-Mansi Autonomous Area.
4. Conducting anthropological interviews (at least 30) with representatives of indigenous peoples in one or more of the regions of Sakha (Yakutia), Yamal-Nenets Autonomous Area, or Khanty-Mansi Autonomous Area.
5. Development of proposals on indigenous peoples' adaptation to climate change and permafrost degradation.
