Abstract
Abstract
High-yield agriculture potentially reduces pressure on forests by requiring less land
to increase production. Using satellite and field data, we assessed the area
deforested by industrial-scale high-yield oil palm expansion in the Peruvian Amazon
from 2000 to 2010, finding that 72% of new plantations expanded into forested areas.
In a focus area in the Ucayali region, we assessed deforestation for high- and
smallholder low-yield oil palm plantations. Low-yield plantations accounted for most
expansion overall (80%), but only 30% of their expansion involved forest conversion,
contrasting with 75% for high-yield expansion. High-yield expansion minimized the
total area required to achieve production but counter-intuitively at higher expense
to forests than low-yield plantations. The results show that high-yield agriculture
is an important but insufficient strategy to reduce pressure on forests. We suggest
that high-yield agriculture can be effective in sparing forests only if coupled with
incentives for agricultural expansion into already cleared lands.
