The end of the agricultural frontier and land grab in the world

At the beginning of the new century we are confronted to the need of rethinking how unsustainable it is an economic system that pretends to grow indefinitely on a finite basis of natural resources. In the meantime we observe a lag in the offer of certain commodities and of some renewable and nonrenewable natural resources, as well of a rising in their prices. At the same time, some governments and private capital are concentrating the available resources, mainly in non-developed nations. In this paper we will explore this trend focusing on agricultural land.
