What are the cons of land grabbing? are there any pros?

One of the effects of the food price crisis on the world food system is the increasing acquisition of farmland in developing countries by other countries seeking to ensure their food supplies.  This brief analyses the pros and cons of land acquisitions in developing countries by capital rich economies. It argues that acquisitions have the potential to inject much needed investment into agriculture and rural areas in poor developing countries resulting into creation of farm and off-farm jobs and development of rural infrastructure. Other possible positive spillovers include resources for new agricultural technologies and practices as well as future global price stability and increased production of food crops. On the other hand, this could also impact negatively on poor local people, who risk losing access to and control over land on which they depend.
