最近关于经认证出口作物经济可持续性的实证文献表明，提高产量的认证标准对改善农业收入和家庭福利很重要。然而，关于有机认证对采用农业生态实践的影响的证据有限。在本研究中，我们使用来自加纳菠萝生产者的独特农场层面数据来检查有机认证对农业生态实践（如有机肥料、有机病虫害和杂草控制、作物轮作和水土保持）使用的影响，以及使用这些措施如何影响农业成果（如投资回报）。我们的实证结果表明，有机认证增加了农业生态实践的使用，尽管起点很低。利用广义倾向得分方法，我们发现农业生态实践利用强度与投资回报之间存在正的非线性关系。(C) 2013 Elsevier B.V.版权所有
The recent empirical literature on economic sustainability of certified export crops shows that certification standards that enhance yields are important for improving farm revenues and household welfare. However, limited evidence exists on the impact of organic certification on the adoption of agro-ecological practices. In this study, we use unique farm-level data from pineapple producers in Ghana to examine the impact of organic certification on the use of agro-ecological practices such as organic fertilizers, organic pest and weed control, crop rotation, and soil and water conservation, as well as how using these measures affect farm outcomes such as return on investment. Our empirical results reveal that organic certification increases agro-ecological practice use, although from a very low starting point. Using a generalized propensity score approach, we show that there is a positive, but nonlinear relationship between the intensity of agro-ecological practice use and return on investment.
