On the edge of the Amazon, efficiency mattersIntensified croplands that grow commodities like soybeans and maize are becoming more common in the Eastern Amazon; here, primary Amazon forest exists meters away from high-productivity agricultural fields.

As land resources come under more and more pressure — to grow food, support cities and house valuable ecosystems — scientists, activists and others are on the hunt for better ways to manage the terrestrial biosphere. One strategy is to increase the efficiency of croplands and pasture lands, particularly in ecosystems such as the Amazon forest where converting more land to agricultural use is environmentally costly.

As the world’s largest contiguous tropical forest, Amazonia is an important store of carbon, provides habitat for biodiverse communities and plays a part in regulating the global water cycle.

Moreover, the Amazon is a prime candidate for exploring whether increasing efficiency can help make agricultural land use more sustainable. Recently, David Lapola of Universidade Estadual Paulista and colleagues pointed out in the journal Nature Climate Change that agriculture in Brazil, including Amazonia, is intensifying and becoming more dominated by commodity production, leading to systematic changes in land use. This intensification has been accompanied by lower rates of deforestation.
