Economic evaluation of ecosystem services as a basis for stabilizing rainforest margins? The example of pollination services and pest management in coffee landscapes

摘要: The determination and evaluation of ecosystem services provides crucial information for a comprehensive strategy to preserve near natural habitats such as rainforest margins. We show results an economic coffee bee pollination pest control in two distinct tropical regions: low human-impact area Indonesia with continuous forests neighboring agroforestry high-impact landscape Ecuador almost no forest fragments left. evaluate comparing destruction scenarios, where yields depend on providing nesting sites foraging bees present three novel approaches: first, we how net revenues adjacent considering berry weight addition fruit set, thereby more evaluation. Second, combine our findings assessment management affecting production. Third, determine welfare effects land-use changes including the fact that former forestland is normally used alternative crops. In both regions, crop exceed values, generating incentives convert margins even if owners would be compensated services. promotion certified “biodiversity-friendly” feasible option maintain shade-coffee systems conservation purposes. This special importance areas only small remain. conclude analysis necessary adequately preservation enhancement within mosaic competing systems.
