1 Drivers, Pressures, Impacts, Response Analysis Of Peatland Fire In Sumatra, Indonesia Hesti L. Tata, Budi H. Narendra, Kirsfianti L. Ginoga Forest Research & Development Centre Forest & Environment Research Development & Innovation Agency IFA 2017 Conference,Cairns, August 2017

2 Tropical (peat)-swamp lands Flecker Botanical Garden, Cairns Peat swamp forest, Tumbang Runen, C. Kalimantan (2014)

3 The importance of peatland ecosystem

4 Peatland Hydrological Unit peatland as a landscape River Organic matter < 1m > 3m < 1m Mineral Soil River Utiization Protection Utilization In natural condition, it contains water 13 x of its biomass. High acidity, low nutrient content. Depth varied: 1 - >10 m Total peat carbon store in Indonesia within: 13.6 GtC to 40.5 GtC (Warren et al., 2017).

5 Current problems: (Schematic illustration of CO2 emission from drained peatland;source: Hooijer et al., 2016)

6 Canals developments

8 Research questions: Does organic soils (peatlands) are more susceptible to fire than mineral soils? What does driven factor, pressure, impact and response of peatland fire? What does current status of hotspots in Indonesia?

9 Peatland Hydrological Unit

10 Total burnt area (per ): 2,6 million ha, which covers 927,132 ha of peatlands (DG Forest Plannology, 2015).

11 Map of Hotspot Distribution in , in Pelalawan District, Riau Province

20 Hotspot occurrence in relation with precipitation (Case in Musi Banyuasin, S. Sumatra) (Source: Tata et al. 2017)

21 Fire is not only driven by biophysicals and climate factors, but also Driven by human: Forest acquisition and land conflict (Case in Tanjabar-Jambi, Pelalawan-Riau, Muba-S. Sumatra and Tripa-Aceh). (Source: PFRM report, 2015)

22 Peatland Fire: Case in Tripa, Aceh Oil palm as driven factor (Source: Tata et al Will funding to Reduce Emissions from Deforestation and (forest) Degradation (REDD+) stop conversion of peat swamps to oil palm in orangutan habitat in Tripa in Aceh, Indonesia? Mitig Adapt Strateg Glob Change 19: )

24 What does driven factor, pressure, impact and response of peatland fire? (Source: Tata et al., Stopping haze when it rains: lesson learnt in 20 years of Alternatives-to- Slash-and-Burn research in Indonesia. ASB Brief no.45. Nairobi. ASB Partnership for Tropical Forest Margins. 6p. )

25 Impacts of fire * Impact of fire on vegetation, soil, air and water quality. * Impact on health * Impact on economic development

26 Responses President s Instruction 8/2015 peatland moratorium President s Instruction 11/2015 on the improvement of fire prevention. President s Regulation 1/2016 on Peatland Restoration Agency Regulations in national and provincial levels, such as: revision of PP71/2014 into PP54/2016, Permenhut 14-16/2017, Regulation at Provincial levels: Governor s regulation of Riau, Jambi, S. Sumatra Provinces in zero burning policy and fire prevention. Strenghtening law enforcement

27 Current Condition: Hotspots data in Indonesia in Hotspot (NOAA) Month Data source from Sipongi (Tata & Ginoga, Pengendalian Kebakaran Hutan dan Lahan. Media Brief. Pusat Penelitian & Pengembangan Hutan. Edition: August 2017)

28 Way forwards: Improving synergy among relevant partners on fire prevention. Accelerating peatland restoration action Cultivation on wet and/or rewetted peatland using native species, which has economic value and adaptive in rewetted condition. For Indonesian, book of Prospek paludikultur ekosistem gambut indonesia (Tata & Susmianto, 2016) can be as one of references. people tend to prevent a productive land from fire.
