1 Topic C1. Reducing emissions and enhancing removals (land-use change, fire, drainage) J Boone Kauffman and Daniel Murdiyarso

2 Topic C1. Slide 2 of 21 Implementing mitigation (emissions reduction) strategies in forests Why it is important to act now? Intact/Restored ecosystems:  are more buffered (resistant) to collapse or decline with a changing climate or other stresses;  have a higher degree of resilience – the capacity to recover following stress or disturbance;  will provide more ecosystem services – e.g. biodiversity, water quality, aesthetics and carbon storage;  may be of value and interest for carbon financing for climate change mitigation

3 Topic C1. Slide 3 of 21 Carbon sequestration is an ecosystem service that has not received value until recently Net primary productivity (NPP) - The net amount of fixed C in organic matter by photosynthesis after the needs of the plant have been met. GPP- Respiration = NPP About 95% of CO 2 emissions would occur if humans did not exist on Earth - natural decay of plant materials is about 220 billion tonnes of CO 2 each year.

4 Topic C1. Slide 4 of 21 Tropical forested wetlands are ecosystems that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support a prevalence of forest vegetation typically adapted for life in saturated soil conditions (e.g. mangroves, freshwater swamps, floodplain forests).

5 Topic C1. Slide 5 of 21 How much carbon can be found in forests? Donato et al. 2011, Kauffman et al. In press, Kauffman et al 2003.

6 Topic C1. Slide 6 of 21 An example of forest carbon stocks: Tropical forests and mangroves of Costa Rica Dry Moist Wet Rainforest Mangrove Kauffman et al. (In press) Mg/ha 400 Mg/ha

7 Topic C1. Slide 7 of 21 Kauffman et al. (2014) Ecological Applications

8 Topic C1. Slide 8 of 21 We need to determine the pathways and processes of emissions

9 Topic C1. Slide 9 of 21 Currently, on average, between 1-7% of blue carbon sinks are being lost annually Upstream disruptionsAquaculture Rice/Agriculture Road development/ hydrological disruptions Coastal development

10 Topic C1. Slide 10 of 21 Currently, the impacts of land use/land cover change are impacting biodiversity to a much greater extent than global climate change

11 Topic C1. Slide 11 of 21 Global loss of blue carbon sinks (total % loss and annual rate of loss) Global area (km 2 )Global lossAnnual rate of ecosystem loss (%)/year References Mangroves 137, % (since 1980s) 30–50% (since 1940s) 0.7–3%Valiela et al. (2001); Alongi (2002); FAO (2007); Spalding et al. (2010) Sea grass 177,000–600,000 50% (since 1990s)~7%Costanza et al. (1997); Duarte et al. (2005); Waycott et al. (2009) Salt marshes 20,000–400,000 Salt marshes 25% (since 1800s) 1–2%Bridgham et al. (2006); Duarte et al. (2008) Area of the worlds forests = 39 million km (Pan et al. 2011) Adapted from Mcleod et al. ( 2011)

12 Topic C1. Slide 12 of 21 How to determine emissions from land-use/land-cover change Gain-loss method Stock difference method

13 Topic C1. Slide 13 of 21 Stock difference method (C t2 – C t1 ) (t 2 – t 1 ) ΔC = annual carbon stock change in the pool C t1 = carbon stock in the pool at time t 1 C t2 = carbon stock in the pool at time t 2 C stock at time 1 C stock at time 2 ΔC =

14 Topic C1. Slide 14 of 21 Donato et al. 2012; Hughes et al. 2000; Kauffman et al. 2013; Pendleton et al. 2013; Kauffman et al. In press.

15 Topic C1. Slide 15 of 21 Gain-loss method ΔC = ΔC G – ΔC L ΔC = annual carbon stock change in the pool ΔC G = annual gain of carbon, tonnes ΔC L = annual loss of carbon, tonnes C stock C uptake via growth Disturbance Harvest Emissions

16 Topic C1. Slide 16 of 21 Example of emissions from peat swamp forests and oil palm plantations – Tanjung Puting National Park, Indonesia (Novita 2015) Peat net annual balance of GHG in the primary forest and oil palm plantations from tropical peatlands of Tanjung Puting Land-use system CO 2 CH 4 N2ON2OGHG total Forest15.37± ± ± ± 0.5 OP14.53± ±0.21.5± ± 0.3 Contribution (%) of CO2, CH4 and N2O to total GHG emissions from primary forest and oil palm plantations in Tanjung Putting (from Novita PhD thesis 2015).

17 In addition to C stocks, there exists unique biodiversity values in tropical wetlands Topic C1. Slide 17 of 21

19 Topic C1. Slide 19 of 21 Why are tropical forested wetlands attractive for REDD+ and other NAMAs? Conservation of biodiversity Coastal zone protection Fisheries Loss of livelihoods and culture Erosion Degradation of adjacent communities (sea grass and coral reefs) Carbon emissions/loss of C sinks Loss of other ecosystem services.
