The Citarum River Basin is the most strategic river basin in West Java Indonesia, home to 9 million people and supplying about 80% of Jakarta’s raw water. The rapidly diminishing montane forest here is recognized by WWF as one of the 200 most critical global ecosystems. Frequent flooding over the last 3 years has resulted in over 100 deaths, destroyed over 14 000 houses and caused over 170 000 local people to become homeless and jobless (source: BNPB, 2019).
With an average 1 ha land ownership per farmer, the transfer from vegetables to coffee planting will help to double family annual income through coffee alone (from 1290 to 2813 USD per family), with potential for an additional 2000 USD per family from forest fruits and fragrant roots. Soil erosion and flooding frequencies and scale in the watershed will be reduced.
