Additionally, an older law that restricts farmers to clearing no more than 20 percent of their land is finally being enforced. If properly followed, this law could radically change the current patterns of deforestation. While in the past most farmers have largely ignored the law, in the years since Stang was murdered government pressure has increased on grileiros and farmers who have cleared too large a percentage of their land. In Mato Grosso, Governor Maggi helps such farmers by allowing them to buy up forest areas adjacent to their farms in order to supplement their percentage of forested land. Thanks to these and other efforts, recent forest surveys seem to indicate a decrease in the rate of deforestation of the Amazon.
