英文文献摘要：
In low potential agricultural areas like the Honduran hillsides characterized by soil degradation and erosion, organic agriculture can provide a means to break the downward spiral of resource degradation and poverty. We use original survey data to analyze the factors influencing the decision to convert to organic agriculture. Previous studies have emphasized the role of spatial patterns in the diffusion and adoption of agricultural technologies in general and organic agriculture in particular. These spatial patterns can result from a variety of underlying factors. In this article we test various potential explanations, including the availability of information in the farmer's neighborhood, social conformity concerns and perceived positive external effects of the adoption decision, in a spatially explicit adoption model. We find that farmers who believe to act in accordance with their neighbors' expectations and with greater availability of information in their neighborhood network are more likely to adopt organic agriculture. Furthermore, perceived positive productivity spillovers to neighboring plots decrease the probability of adoption. We discuss the implications of our findings for the dissemination of sustainable agricultural technologies in low-potential agricultural areas in developing countries.
在以土壤退化和侵蚀为特征的低潜力农业区，如洪都拉斯山坡，有机农业可以提供一种手段，以打破资源退化和贫困的恶性循环。我们使用原始调查数据来分析影响转向有机农业的因素。以往的研究强调了空间格局在一般农业技术的传播和采用方面的作用，特别是在有机农业方面。这些空间格局可能是由多种潜在因素造成的。在本文中，我们在一个空间显式收养模型中检验了各种可能的解释，包括农民社区信息的可得性、社会整合关注以及对收养决定感知的积极外部效应。我们发现，相信按照邻居的期望行事，并在邻居网络中获得更多信息的农民，更有可能采用有机农业。此外，感知到的对邻近地块的正生产力溢出降低了采用的概率。我们讨论了我们的研究结果对在发展中国家低潜力农业地区传播可持续农业技术的影响。
