It has been claimed that foreign investors are purchasing land that has been left idle; thus, by bringing it into production, the purchases are increasing the availability of food overall. But the Land Matrix Partnership report found that this is not the case: roughly 45% of the purchases involved existing croplands, and almost a third of the purchased land was forested, indicating that its development may pose risks for biodiversity.
外国投资者宣称自己购买的是闲置土地，因此，通过让这些土地形成产出，土地买卖增加了粮食供应量。但土地矩阵合伙组织的报告发现并非如此：约45%的土地买卖对象是已存在的耕地，几乎三分之一的交易土地是林地，这表明开发可能威胁生物多样性。
