Land grabbing has gained momentum in Latin America and the Caribbean during the past decade. The phenomenon has taken different forms and character as compared to processes that occur in other regions of the world, especially Africa. It puts into question some of the assumptions in the emerging literature on land grabbing, suggesting these are too food-centered/too food crisis-centered, too land-centred, too centred on new global food regime players – China, South Korea, Gulf States and India – and too centred on Africa. There are four key mechanisms through which land grabbing in Latin American and the Caribbean has been carried out: food security initiatives, energy/fuel security ventures, other climate change mitigation strategies, and recent demands for resources from newer hubs of global capital. The hallmark of land grabbing in the region is its intra-regional character: the key investors are (Trans-)Latin American companies, often in alliance with international capital and the central state. Initial evidence suggests that recent land investments have consolidated the earlier trend away from (re)distributive land policies in most countries in the region, and are likely to result in widespread reconcentration of land and capital. 相似文献

Ben Affleck's film ARGO is a good film, but not all the details are accurate. This article is by Martin Williams, the British diplomat who, contrary to the picture painted in the film, personally escorted to safety the Americans who had escaped when the Iranian Revolutionary guards took over the US Embassy. He sets that episode in the broader context of his personal experience of working during a complicated period during which initially there were major commercial opportunities for British firms, and then the power of the Shah started to wane, and finally he was overthrown. The installation of a very different regime entirely changed the approach which diplomats needed to adopt in Tehran. 相似文献
