Enhancing Emissions Reduction and Carbon Sequestration in Forests

This presentation discusses the importance of implementing mitigation strategies in forests to reduce emissions and enhance carbon removal. It highlights the benefits of intact/restored ecosystems, carbon sequestration as an ecosystem service, and the carbon stocks in tropical forests. The focus is on the significance of acting now to protect these valuable ecosystems.

Presentation Transcript

1. TopicC1. 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 CO2 emissions would occur if humans did not exist on Earth - natural decay of plant materials is about 220 billion tonnes of CO2 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? Examples of ecosystem C stocks of tropical forests Carbon Mg/ha) 2500 2000 1500 1000 500 Aboveground 0 Belowground Donato et al. 2011, Kauffman et al. In press, Kauffman et al 2003.

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 disruptions Aquaculture Road development/ hydrological disruptions Coastal development Rice/Agriculture

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 (km2) Global loss Annual rate of ecosystem loss (%)/year References Mangroves 137,760-152-361 20% (since 1980s) 30 50% (since 1940s) 0.7 3% Valiela et al.

( 2011) Area of the worlds forests = 39 million km (Pan 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 (Ct2 Ct1 ) (t2 t1) C = C = annual carbon stock change in the pool Ct1 = carbon stock in the pool at time t1 Ct2 = carbon stock in the pool at time t2 C stock at time 1 C stock at time 2

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