This small structure is the ECHO Asia Seed Bank’s earthbag house that is nearing completion. ECHO promotes community-based seed sharing and saving. It is also part of their mission to recommend appropriate ways for communities and organizations in the developing world to better store seeds.
James (ECHO Asia intern) and Lue (Assistant Seed Bank Director) were trained in earthbag house construction by Engineering Ministries International (eMi). To prevent the invasion of surrounding warmer air (the seed bank is located in a tropical/sub-tropical region), a small door with a foam interior and a thick but light ceiling composed of sacks filled with burnt rice husks were installed. And to keep costs low, almost the entire structure was made from local, cheap materials, including a roof of fan palm thatch.
Data loggers will be installed to record the interior temperature and relative humidity. These will be compared with outside readings over a period of one year. So we look forward to reporting on the long term results of the modification of temperature by the earthbag house and the potential of such structures for community-based seed storage in the tropics.
