Sumberbulu Micro-Watershed

The Sumberbulu Micro-Watershed Model, located in Bringin and Bambang village, Malang, East Java, is a part of Bangsri Sub-Sub-Watershed, Lesti Sub-Watershed of Brantas Watershed. Geographically, it is located in the western slope of Mt. Semeru, so it is much affected by the volcanic activity as well as being the place of the material deposit. The area of Sumberbulu Micro-Watershed Model is 504.06 Ha with a total population of approximately 3,948 people in Bambang Village and 6,159 people in Bringin Village.
Sumberbulu Micro-Watershed Model has a new potential ecotourism site for its waterfalls and abundant water resources which comes from a spring from the mountain.

Current Situation:

  • The material originating from Mt. Semeru, resulted in a lot of sand deposit and potentially massive sand mining
  • The sand mining activities reducing soil fertility and soil animal ecosystems, which may lead to a greater potential of land damage in the future
  • Intensive mining resulting in a hanging wall that may cause sudden landslides and the occurrence of river sedimentation
  • The increasing population of “embug” larvae that attacks almost all commodities grown in sandy soil which affects in decreased agricultural and plantation productivity
  • • High rain intensity which affects the agricultural plants and makes them vulnerable and susceptible to yellowing “curly leaf”
  • • Root exposure caused by splash and sheet erosion
  • • The household waste that is discharged into the river which results in water pollution

Project Action Plan

  • Restoring the degraded land of the sand-mining site by involving local communities in the procurement of quality tree seeds and plantations
  • Restoring ecosystem and the habitat as well as the food chain within into their natural condition
  • Raising an awareness and mainstreaming information to the community about the rules regarding sand mining and its impact on the environment and land degradation (facilitating the fair implementation of PES (Payment Environmental Services) for the communities)
  • Training and developing the communities about producing “embug”-free compost with fermentation technique and nutrient enrichment
  • Training and mainstreaming about household waste management
  • Developing institutional communities to implement Rio Conventions and incentive mechanism
