What are ecosystem services?
The provision of natural resources or process valued by humans
What are the four main types of ecosystem services?
Supporting, Provisioning, Regulating, and Cultural services
Give examples of Supporting Services
Soil formation, photosynthesis, nutrient recycling, seed dispersal, and pollination
Give examples of Provisioning Services
Food, water, timber, and fibre
Give examples of Regulating Services
Climate regulation, flood control, disease regulation, and water purification
Give examples of Cultural Services
Aesthetic, recreational (eg. ecotourism, angling), and mental well-being
What is the purpose of Payments for Ecosystem Services (PES)?
To fund protection of tropical forests and biodiversity through monetary incentives
What is the mean value of tropical forest services?
Approximately $1,312 per hectare per year
What does REDD+ stand for?
Reducing Emission from Deforestation and Degradation “plus” conservation, sustainable forestry, and enhancement of forest carbon stocks
How much does the UNFCCC predict REDD+ payments could reach annually?
Up to $30 billion per year
When is REDD+ a win-win for carbon and biodiversity?
When high carbon stores correlates with high biodiversity
Why might carbon and biodiversity not always align?
Some areas have high carbon but low biodiversity, or vice versa
What is the opportunity cost in REDD+?
The lost revenue from potential logging or farming
What are the main threats to Borneo’s forests?
Intensive logging and conversion to plantations (eg. oil palm)
Why is REDD+ expensive in Borneo?
High opportunity costs due to lucrative timber and plantation industries
What is the REDD+ breakeven carbon price in the Amazon?
$7.9-10.54 per tonn CO2
Why is REDD+ more cost-effective in the Amazon than in Borneo?
Lower opportunity costs and comparable to voluntary carbon market prices
What land use dominates the Tropical Andes?
Low-intensity cattle farming on marginal pasture?
What are the co-benefits of regrowth in the Tropical Andes?
Carbon recovery and biodiversity restoration, including IUCN Red-listed species
How much carbon stock can recover in 30 years in the Andes?
About 50% of original carbon stock
What are the typical voluntary carbon market prices?
Around $7.8 per tonne CO2
Where can REDD+ protect biodiversity cheaply?
Andes ($2/tCO2), NE India (<$1.5/tCO2), East Africa ($6.5/tCO2)
Where is REDD+ less feasibly economically?
SE Asia ($47/tCO2) due to high costs
Where is REDD+ less feasible economically?
SE Asia ($47/tCO2) due to high costs
