One of the major reasons of deforestation in Nepal is cutting down tress for wood for construction of buildings. Not only in the urban areas but also in the rural area, where wood availability is abundant, within the vicinity of community forestry, the overuse of wood creates pressure to degrade forest land.
The massive or unnecessary use of wood for constructing even a small building can easily be replaced by earth-filled bags. By using earth-filled bags we can simply make walls and other structures which are stronger, cost effective and beautiful as compared to other construction materials. The haphazard cutting of trees and overuse of wood also cause global warming and climate change. As trees helps to reduce carbon release, earthbag building helps to reduce the use of wood for construction. The dirt under your feet can be used for excellent building materials.
Typical houses in Nepal use 200 cubic feet of wood. The same amount of wood can build 20 houses if walls are made with earthbags. 10 cubic feet of wood is enough for one house to make doors and windows. This is how earthbag building can preserve forests and minimize the high use of cement, brick, iron and steel in building conventional house, the main cause of climate change.
