A study reviews policy interventions and commodity market effects to slow Amazon deforestation, finding positive incentives as effective as penalties. The review suggests establishing simple incentives for responsible farmers to preserve forests.
Research from Brown University suggests that the decline of suitable land for agriculture is a key factor in slowing deforestation in Mato Grosso, Brazil. The study found that land with characteristics such as flat terrain and proximity to roads was initially converted to agriculture, but this type of land is becoming increasingly scarce.
Reducing tropical deforestation significantly reduces carbon dioxide emissions by up to one-fifth. Tropical forests absorb almost two billion tonnes of carbon annually, but human activities like logging and biofuel production lead to equivalent losses.
A new study suggests that encouraging the intensification of Brazil's cattle production or taxing conventional pastures could deliver a substantial cut in global greenhouse gas emissions. By reducing deforestation, Brazil may be able to spare up to 80% of recently deforested land.
