Best Practice Peat Management (BPM) in existing plantation

  1. 1. Best Practice Peat Management (BPM) in existing plantation Dr. Götz Martin, Golden Agri-Resources Ltd Bonn, December 1, 2018 1
  2. 2. Short introduction to Golden Agri-Resources (GAR) 2 • An integrated palm oil plantation company • Largest palm oil grower in Indonesia • Total revenue: over US$7.5 billion • 2.72 million metric tonnes of crude palm oil (CPO) and palm kernel (PK) produced in 2017
  3. 3. Best practice peat management is in the very best interest of the palm oil industry Description •Draught: Palm yield is severely depressed in drought periods. From an agronomic perspective, moist soils can provide stable yields throughout the year. •Flooding: uncontrolled flooding is causing major losses every year and/or is causing high cost for running water pumps •Substrate: If the peat layer is dropped below the natural drainage limit the industry is loosing the substrate to grow their income source and is loosing its investment. Agronomy •Low GHG emissions are required to sell palm product to some selected markets and to enjoy price premiums over non- sustainable growers. Environment Palm growers have made a long term investment and have a vested interest to maintain their growing substrate as good as possible 3
  4. 4. To be able to manage and maintain peatland we need to understand the situation we have to work with 4 4,5 km 11,1 km 7,1 km # PT Bumipalma Lestaripersada (BPLP) is located Kab. Indragiri Hulu, Riau Province. # Geographically located at : 102o54’ – 103o06 BT and 0o35’ – 0o41 LU # With a wide area of management is 6.729, 21 Ha
  5. 5. A wide range of data is needed to understand your peatland situation 5 Peat Characteristic Peat Drainage Problems Peat Hydrology  Elevation  Peat distribution  Peat thickness  Peat subsidence  Water supply  Water loss  Overcapacity  Rainfall  Water level surface  Canal condition  Peat water management zone Drainage Limit Time (DLT) Future Drainage Management Solutions
  6. 6. With the collected information the to be managed area is divided into water management zones 6 Zona Laju Subsidensi (cm/tahun) Zona 1 2,83 Zona 2 3,63 Zona 3 1,07 Zona 4* 1,07 Zona 5* 1,07 *) Zona 4 dan 5 menggunakan data pada zona terdekat
  7. 7. Water management and monitoring infrastructure is using basic and cost efficient technology 7 Water and subsidence monitoringWater management infrastructure Watergate Overflow Stop Block Waterpump Subsidence pole Palscale Sumur PantauLogger Sumur PantauLogger
  8. 8. Peat subsidence rates differ depending on plantation age and agronomic treatment e 5. Effect of peat decomposition on groundwater table at various distances from collection (water level in collection drain at 50 cm). Figure 6. Yearly average and accumulated peat subsidence in the study area. Ref : Faizal Parish RSPO RT15 (2017) 8
  9. 9. Drainability assessments are required to justify replanting 9 • New RSPO requirements for drainability assessment-5 YEARS PRIOR TO REPLANTING • The assessment result is used to set the timeframe for future replanting, for at least 40 years, or two cycles, whichever is greater, before reaching the natural gravity drainability limit for peat.
  10. 10. The RSPO is providing best practice management guidelines for existing plantation and rehabilitation 10
