1 bn acres of unused agricultural land world wide could produce biofuels, according to the Stanford News Service in a piece called Feeding and fuelling the future: the bioenergy potential of reviving abandoned agricultural land.
The authors estimate that this is about a quarter of the total agricultural land in use. Land is abandoned for a number of reasons, but plants could fix nitrogen and carbon to help them recover as well as provide biofuels.

Jerry,
I guess the question is not so much how long is a piece of string, but how do you measure it.There are many differing estimates. If anybody has any particular claims to a good one, we'd both like to hear it.

Arable land & permanent crops and agricultural area
This category refers to the use of land cultivated for productive activities such as cereals, root crops, industrial crops (e.g. cotton, tobacco, oilseeds), vegetables, flowers and ornamental plants, orchards, vineyards, olives, etc.
The total agricultural area in the world amounts to 5.0 billion ha. Of this, about 1.5 billion ha (30.4%) is arable land and land under permanent crops. A decreasing growth rate of 0.3% has been noted over the ten year period.
