The effect of agricultural certification schemes on biodiversity loss in the tropics.

Scholars have quantified the impact of the production and consumption of commodities, in particular agricultural commodities, on biodiversity loss. Certification schemes, meanwhile, have been instituted as a means to limit biodiversity loss caused by the production of some of these commodities. This paper clarifies how biodiversity loss can be limited by certification schemes in oil palm and fastwood plantation concessions by applying three methodological approaches to biodiversity assessment. We consider concessions in West Kalimantan province, Indonesia, as an example. We found that certified plantation concessions that are committed to deforestation-free production are limited in their ability to prevent further biodiversity loss, due to the past conversion of forest habitats to plantations. Concession holders can improve forest habitats through corridor development and other measures, which would mitigate, but not prevent, further biodiversity loss. We suggest a broadening of focus from protecting natural habitats within concession areas, to the wider landscape around concessions in collaboration with neighbors. This will require institutional arrangements to enable access to finance and technical expertise. • Approaches to the global biodiversity assessment are used to analyze certification schemes. • Certified plantation concessions are limited in ability to prevent further biodiversity loss. • A broadening of focus to the wider landscape around concessions is suggested.
