The main incentive for the multiform land grabs is the utilitarian, profit-oriented use of land. Among the leitmotivs of the present wave of land grabs, especially on the global South, one could find the increasing ecological problems, and the speculation for the likely future boom of food prices. The centralization of land control and the food production that is dominated by profit based industrialized factory farms is hamstringing agrarian small producers and is aggravating the population of slums; from the other hand it is incompatible with the needs of an ecologically sustainable agriculture and the food sovereignty of the peoples.
