The combination of continued anthropogenic disturbance, particularly deforestation, with global warming may result in dieback of forest in the region  . Losses of biomass as high as 40% are projected in CA with a warming of 3ºC-4ºC, and the Amazon may experience a significant dieback at similar warming levels . Advances in second-generation bioethanol from sugarcane and other feedstock will be important for mitigation. However, agricultural expansion results in large conversions in tropical dry woodlands and savannahs in SA   . The expansion of soybean plantations in the Amazonian state of Mato Grosso in Brazil reached 16.8% yr-1 from 2000 to 2005; and oil palm, a significant biofuel crop, is also linked to recent deforestation in tropical CA  and SA , although lower in magnitude compared to deforestation from soybean and cattle ranching .
