Increasing international pressures (governmental, private, and organizational) on tropical countries to preserve their rainforests. In some cases, international pressure has induced countries to establish rainforest reserves. The government of Madagascar established Masoala National Park under such conditions. One of the reasons it acceded is that by retaining the rainforest it could obtain currency by selling emission credits (Kremen, et al., 2000). The normal pattern of slash-and-burn agriculture and logging in Madagascar is instead the agent of substantial CO2 emissions; thus, continuing this pattern in Masoala would have been a financial loss for the government.
