Flex crops, spread over greater expanses of land, are increasingly interlinked through international exchange in food, feed and fuel. Brazilian exports of sugarcane ethanol to the US are in part influenced by the domestic US production of maize ethanol, which in turn is shaped by the price of feed and the soybean supply.
Flex trees seem to offer timely opportunities for socio-environmentally sustainable solutions, but also present dangers, particularly if such changes accelerate the concentration of land and plantation-based development, whereby forests compete with and may replace food production.
