Since the 1990s many new settlers have come to Petén. The area is also experiencing severe deforestation in its southern half. Deforestation has been particularly rapid near Laguna del Tigre National Park in western Petén. To combat deforestation, Guatemalan president Álvaro Colom proposed dramatically expanding ecotourism around Maya archaeological sites, especially El Mirador, and trying to further develop an agricultural system in the southern portion of the Maya Biosphere Reserve that would prevent further northward migration. He called his plan "Cuatro Balam".
