Interactions of climate change and land-use adverse influences on

Land tenure in Borneo

Black: State borders/riversRed: HPH borders

Permanent forest estate 38 mill ha, 50% of the land

(Production forests for logging)

Production forests

Degraded production forests due tounregulated “conventional” logging

Projection in Borneo

Nearly entire permanent forest estate (50% area)will be highly deteriorated due to logging and droughts

c. Another 40% area will completely lose (has lost) forest covers

Only 8.3% (or 6.2 million ha protected areas) of Borneo will remain relatively intact (but illegal encroachment)

Biodiversity

Land-use(Economic benefits)

Time

Trade-off between land-use and conservation

Protected area

Synergize timber production and conservation

Synergize land-use (timber production), mitigation,

adaptation and conservation

Multiple benefits in timber, climate (carbon) and biodiversity

Is sustainable-forest- management system per se

sustainable?

For a sustainability system to be sustainable

Forest CertificationAn economic incentive

-Consumers pay for the additional cost of the sustainable management

Sustainable forest management(high cost)

Audit Certify

Timbers from certified forests Auction

Products

Green-conscious consumers(premium)

Adequate incentives are necessary

• Forest certification and labeling• REDD incentives (Reducing Emissions

from Deforestation and Forest Degradation)• Payment for Ecosystem Services

Otherwise, we will fail

3 roles of biodiversity in ecosystem-based sustainability

• Provides functions and services: ecological principles in land-use management (protecting keystone species)

• Diagnoses ecosystem health and validity of management (standards and indicators)

• Adds a premium that will be an incentive for producers (institutions with incentives)
