Higher oil palm yields are bad ?

Khor Reports: Environmentalists and others have been concerned about the extensification of oil palm, arguing that expansion should be on degraded land and that the focus should be instead on yield increases. The Indonesian state appears to be moving toward making degraded land easier to use via new regulations. For quite some time, there has been a great deal of work and effort going into intensification or higher yields. So you would have thought that better yields achievements would be welcomed. However, an article in Science (covered by scientificamerican.com) now argues that yield increase is NOT a good thing after all.... Hard to please on any front? It makes oil palm planting too valuable / lucrative?

Good Palm Oil Yields Could Be Bad News by Cynthia Graber; "Increased palm oil yields could unintentionally have the effect of creating a bigger demand for land for even more palm oil planting. Cynthia Graber reports... in an article in the journal Science, researchers show how the increased yield could in fact lead to even more tropical destruction. Because as the value of palm oil planting increases, farmers could want to plant on even greater tracts of land. Which is bad news....  Also, a future increase in supply could eventually lead to a decrease in prices. So palm oil could out-compete, say, rapeseed oil from Canada. Which would lead to an even higher demand for palm oil. Which is worse news....  In addition, current low yields and high production costs means oil palm is not planted much in Africa and South America. But higher yields could make oil palm attractive to planters in those regions, leading to even more tropical forest destruction. [L. R.

With a growing global population and increasing per capita consumption, reconciling agricultural production with biodiversity conservation is a major challenge to humanity (1). A frequently promoted solution to stem the tide of agricultural expansion is to increase crop yields, allowing global demand to be met without further tropical forest losses. Recent genome sequencing of key crops such as oil palm, eucalyptus, rubber, soybean, rice, and cocoa could facilitate substantial yield increases (2–4). Could such yield improvements offer a solution to both tropical forest loss and agricultural demand, or could they pose further challenges to tropical conservation?
