Ecosystem Services in plantations: from economic valuations to market-based instruments
•
1 like•796 views
This document summarizes a study that evaluated ecosystem services under different landscape management scenarios in Australia. The study assessed carbon sequestration, agriculture production, water, biodiversity and timber across 5 future land use scenarios: business-as-usual, mosaic farming landscapes, eco-centric, agro-centric, and abandoned land use. The analysis found that business-as-usual and abandoned land use were not sustainable and led to declining ecosystem services. Agro-centric produced good economic outputs but poor environmental outcomes. Mosaic farming landscapes and eco-centric produced better environmental outcomes but eco-centric was not commercially attractive. Supplemental payments were needed to restore the environment.

2. Economic evaluation of ecosystem goods and services
under different landscape management scenarios
3. Study landscape background
Australian landscapes are changing due to changing demands of
society and climate change and variability
Land use has gone through many cycles of land clearance,
investment, abandonment
Since European settlement of Victoria in the1830s, ~66% of native
vegetation has been cleared
Key NRM issues – declining water quality and quantity, salinity
(irrigation and dryland), deterioration of soils, declining biodiversity,
degradation of rivers and wetlands, increasing weeds and pest
infestations
4. Background – policy context
Bold, strategic and landscape-scale
initiatives are required to reverse
the land degradation
The Australian Government and
regional NRM agencies have
adopted a wide range of
sustainability approaches
Range of market-based
instruments for NRM are being
operated in Australia – e.g., bush
tender, eco-tender
Carbon farming initiative – as a
new economic opportunities for
farmers and land managers
5. Study aims
Identify and define the plausible future land use scenarios
Identify and assess the key ecosystem services such as, carbon
sequestration, agriculture production, water, biodiversity and timber in
heavily modified and fragmented landscape
Assess the projected changes in ecosystem goods and services under
plausible future land use scenarios
Analyse trade-offs and synergies
6. Study area and major land use categories
• Largely degraded from clearing of native
vegetation for agriculture as well as over
allocation of irrigation water
• Rainfall ~350 mm, 70 m asl
• Size: 30,000 ha
• High conservation value
7. Timber
Methods: key research steps
Step I
• Collate spatial and attribute data
• Land use and land cover classification
• Identify and define ES for assessment
Step II
• 3 cost based scenarios, and assumptions
• Estimation of ES flow
• Value per ha
Step III
• Develop and define 5 future land use scenarios
• Identify proposed land use change under each scenarios
• Ecosystem services under each scenario
Step IV
• Spatial assessment – tradeoffs, synergies and interactions
• Policy implications
Carbon
Water
Biodiversity
8. Plausible future land use scenarios
Business-as-usual
• current farming and management systems continue with no significant
changes in land use and land cover in the future
Mosaic farming landscapes
• reconfiguration of irrigated farming landscapes to more sustainable use,
such as improved farming, low rainfall forestry and biodiversity plantings
Eco-centric or environmental plantings
• growing environmental concern and growth of new environmental
commodities such as carbon and biodiversity credits, there will be
substantial increase in environmental plantings
Agro-centric or production oriented
• higher demand of food/livestock production due to continued population
growth in Australia and globally
Abandoned land use
• land abandonment due to the depopulation in rural areas, and significant
uncertainly due to changing climate
10. Calculation - example
NPV is the net present value ($/ha)
P is the price of carbon,
Qt is the quantity of CO2e sequestrated in year t, EC is the establishment
cost,
MC is the annual management cost, and
r is the rate of discount

15. Conclusions
Against any realistic investment criteria returns from carbon alone
may not be commercially attractive in the study region
Additional payments via the Victorian Government’s market based
instruments such as, bush tender makes some scenarios attractive
but they are nowhere close to current expected return from
agriculture
Planting for timber is not commercially attractive as it delivers only
negative or very low returns under all except the most optimistic
scenario (low cost with low discount rate)
16. Conclusions
Business-as-Usual and Abandoned Land Use are not a sustainable
solutions the for future as they lead to a decline in ecosystem
services
Abandoned Land Use potentially threatens native biodiversity and
produces ecosystem dis-services due to potential growth of weeds
and pest animals
Although Agro-centric is commercially attractive but produces poor
environmental outcome, there is also a growing uncertainty due to
declining rural populations, volatile commodity market, and climate
variability
Mosaic Farming Landscapes and Eco-centric produces better
environmental outcomes. However, Eco-centric is not commercially
attractive due to harsh environmental condition and associated low
carbon and timber productivity
Supplemental payments are required to reverse the declining
environmental situation and restore fragmented natural capital
20. With assumed strengths…
Economic signals more effective and flexible
Better resource allocation and efficiency
Filling the funding gap for ES provision
21. … but also lots of confusion
Inconsistent use of terms
Mis-information of policy-makers
An impediment to policy evaluation
22. 1. Direct markets (e.g. NTFPs for conservation)
2. Tradable permits (e.g. transferable development rights, carbon
markets)
3. Regulatory price changes (e.g. eco-taxes or subsidies)
4. Voluntary price signals (e.g. FSC certification)
5. Coasean-type agreements (some PES, conservation concessions)

27. General implications of relying on PES
Establishment of multi-stakeholder agencies as intermediary bodies

28. Results from case studies
Evaluation procedures for the internal governance of farmer groups are
necessary
Multi-stakeholder bodies do not guarantee equal power in decision making
The effectiveness is affected by political purposes
… but is this specific to ‘PES’?
29. Converging results from previous researches
Governance needs to complement economic tools to achieve outcomes
- Impacts of P&P expansion depend on corporate governance and political will;
- Impacts of plantations on forest conservation depend on public support policies;
- Economic valuations in response to demand by policy makers;
- MBIs require proper regulatory frameworks.
