The problem is poverty and the lack of water for drinking and hygiene in the upland barrios. The project will build arborloo or tree toilets to prevent open defecation and as an alternative to flush-pour toilets which is no longer useful in upland areas. Another problem is the lack of local livelihoods and to increase food and nutrition by doing small-scale gardening.
The arborloo toilet is waterless but odorless and after the pit is full after about 6 months use, the whole toilet structure is transferred to another area and the fertilized pit planted with vegetables or fruit trees.
Improvement in health and sanitation due to the arborloo toilets . Improvement in incomes as a result of gardening and animal raising. Improvement in biodiversity due to tree planting.
