Gobi Tree Greenhouse

Country or Countries Where Challenge Takes Place: 

Use local abundance to construct an appropriate greenhouse that can weather the harsh climate and extend the tree growing season of in the South Gobi Desert.

Details: 

 

 

In the South Gobi desert, approximately 15 km from Dalanzadgad, M●CAM has partnered with Batbayar (“Baidaa”) and Jazei (“Jagaa”) and their company Gobyn Undur (English – Gobi Highest).

Gobyn Undur raises Gobi/Saksaul trees and currently has planted 10,000 trees outdoor. However, due to harsh environmental conditions, it is impossible to plant trees year round and the planting season is only during the summer months. Greenhouses could extend the growing season for tree seedlings. Trees in the Gobi will greatly reduce desertification, will manage erosion, and will provide food and water for local herd animals such as camels and horses.

The coordinates of the project are:
103°67’72 longitude (E)
44°16’26 latitude (N)

The Environmental Conditions:
The main external conditions that must be taken into consideration are temperature range and wind. Most days are sunny and the area experiences very little rainfall. However, temperature range year round can be as cold as -50 °C and as hot as 52 °C. Even during a 24 hour period, temperature can change as much as 35 °C/61 °F. 

During spring and fall the wind speed can reach up to 140 km / h
Mean annual wind speed of 6.4-7.1 m/s

 

 

 

This G.I.C. Challenge asks the community to collaborate to develop the technology needed to build an appropriate greenhouse that can weather the harsh climate and in turn, extend the growing season.

Proper covering, framing, and materials will need explicit documentation.
Sand and rocks blown in windstorms are sharp and could penetrate the structure during a gust or sustained wind. Appropriate thickness or provisions for adaptation during a storm must be considered. Currently we do not know the temperature range that seedlings can withstand. Internal structure temperature regulation is important to consider once this specification is determined. Sizes and shapes of the greenhouse are also not yet defined. Production needs will help determine actual size. A starting assumption would be a structure designed to cover approximately 2000 sq feet, in a design layout similar to a traditional high tunnel. If we need further development, we would add additional greenhouses. If we organize multiple greenhouses together, some of the wind could be shielded using specific arrangements and formations.

Commodity: 
Haloxylon ammodendron trees on farm, land near Dalanzadgad city and airport, water springs, well, glass, municipal waste from Dalanzadgad, coal fired electric plant within 10 kilometers. No electric on site but transport to site and roads are very good, easy for glass transportation.
Custom & Culture: 
Haloxylon ammodendron trees are popular in the Gobi Desert as they have large root systems and bring water from depths to the surface. Bark and needles are water rich and provide a food and water source for grazing animals and livestock.
Knowledge: 
Haloxylon ammodendron seeding, planting, growing and harvesting expertise. Local business acumen and local business network links.
Money: 
Value is currently unknown.
Technology: 
Well, pumps, water drip systems, generators, garden equipment
Well-Being: 
Livestock have successfully lived in partnership with this tree for a very long time. Cultivation of the tree is a relatively recent phenomenon but provides the local economy and environment with many benefits. Trees reduce desertification, provide food/water for animals and humans, reduce erosion and provide employment in cultivation, sales and replantation.
