非洲在采用农业生物技术方面一直犹豫不决，在过去十年中落后于全球趋势。布基纳法索是一个例外，这个西非国家在 2009 年商业化推广了 125,000 公顷 Bt 棉花。Bt 棉花可以作为非洲国家如何利用现代、科学驱动的技术来增强可持续性的一个有效范例，以提高生产水平，同时减少投入使用和能源消耗。本文通过总结先前发表的研究的经验证据，报告了 Bt 棉花对布基纳法索棉花行业可持续发展的潜在影响。根据六年田间试验和生产者调查收集的已发表数据的总结，Bt 棉花使棉花产量平均提高了 21.3%，每公顷收入增加了 106.14 美元。使用能量平衡模型，引入 Bt 棉花还可节省 6.6% 的能源使用。生产率和经济回报的显着提高可能成为布基纳法索和其他非洲国家摆脱十年左右的停滞并重新获得在世界棉花市场的竞争地位的催化剂，同时提供环境和社会效益。
Africa has been hesitant to adopt agricultural biotechnology, lagging behind global trends over the past decade. One exception is Burkina Faso, a West African country that commercially released 125,000 ha of Bt cotton in 2009. Bt cotton may serve as a working example of how African countries can enhance sustainability using modern, science-driven technology to increase production levels while reducing input use and energy consumption. This paper reports the potential impact that Bt cotton can have on sustainability in Burkina Faso’s cotton sector based by summarizing empirical evidence from previously published studies. Based on the summary of published data collected from six years of field trials and producer surveys, Bt cotton increased cotton yields by an average of 21.3% and raised income by $106.14 per ha. Using an energy balance model, the introduction of Bt cotton would also result in a 6.6% saving in energy use. The significant increase in productivity and economic returns could be the catalyst for Burkina Faso, and other African countries, to emerge from the decade or so of stagnation and regain their competitive stance in world cotton markets while providing environmental and social benefits.
