For the last 5 years SGG's main activity has been promotion of agroforestry. Tropical tree planting has both environmental benefits [e.g. soil moisture retention, protection against soil erosion, climate change mitigation] and huge humanitarian benefits [e.g. additional farm income, fruit for better nutrition].
Crucial aspects to the success of tree planting are:
1. allowing farmers to plant species of their own choice
2. paying farmers to care for trees during first year after planting.
