Cover image: Pictured is a national forest in the Luangwa Valley of Zambia, where deforestation has been inadvertently spurred by economic interventions to promote cotton farming. Christopher B. Barrett et al. describe several mechanisms linking poverty traps with biodiversity conservation. Unintended consequences can result when social institutions fail to reconcile human needs with sustainable natural resource management practices, necessitating monitoring and evaluation of both social and biodiversity metrics?in these closely coupled systems. See the article by Barrett et al. on pages 13907–13912, which introduces the Biodiversity Conservation and Poverty Traps Special Feature.?Image courtesy of John Fay.
