In the 20 countries of the South (and the total of 63 projects) examined there are some 2 million households farming 4 million ha with sustainable technologies and practices (Table 2). These data do not represent acomprehensive survey of sustainable agriculture in each of the countries. However, they do illustrate what hasbeen achieved by specific projects and what could be replicated elsewhere. Most of these improvements have occurred in the past 10 years, many in the past 2-5 years. The assumption is that these are representative of what is possible on a wider scale. It might be argued that they are successful only because they have occurred where there is a combination of the least resistance and most opportunity, although the sheer diversity of approaches and contexts make this unlikely. Moreover, many of the improvements are occurring in remote and resource-poor areas that have commonly been assumed to be incapable of producing food surpluses.
