摘要

2011年7月10日至23日,在社区生态农业网络(www.CanUnite.org)的赞助下,第12届国际生态农业短期课程在加州大学圣克鲁斯分校举行。这门课的题目是“食品系统向可持续发展的转变:加州模式”。从佛罗里达州到阿拉斯加州,从缅因州到加利福尼亚州,代表美国九个国家和不同地区的32名参与者和多位演讲者聚集在一起,深入介绍了农业生态学如何成为重新设计当今粮食系统的重要和可行方法。通过将转换过程表示为一系列转换级别(参见JSA第33卷,第11号)。1, 1 - 2页),食物系统的改变不仅是必要的,而且是合理的。基于生态学和生态系统思想,农业生态学被塑造成一门以行动和变革为导向的科学,我们中的许多人认为,要避免最近被称为迫在眉睫的“粮食危机”,就需要这种科学。农业生态学不是依赖更多被标榜为新绿色革命的技术,而是一种信息密集型的方式,重新设计粮食生产过程,使多样化、相互作用和弹性结合起来,创造出新兴的可持续性质量。但在这个过程中也很清楚,仅靠农民无法改变整个粮食系统。它还需要食物链另一端的人们——吃这些食物或使用其他农产品的人——的充分参与。在几十年的粮食系统政策和发展以高产、聚集和集中为重点之后,种植者和食客变得如此孤立和分离,以至于两者都被剥削了。种植者不知道谁在消费他们的产品,而食客也不知道谁在种植他们的食物,它是如何种植的,或者它是在哪里种植的。通过重新连接粮食系统中这两个最重要的部分,农业生态学课程展示了如何通过重新发展可持续性文化,我们可以完成实现这一目标所需的转型过程(称为转型过程中的第4级)。该课程包括参与者对四个不同规模的当地有机农场的观察和对食品系统的整合。我们还听取了主要粮食系统转型项目的意见,如“变革之根”、“食物共享”、

Transforming Food Systems to Sustainability with Agroecology
July 10–23, 2011, the 12th Annual International Agroecology Shortcourse took place at the University of California Santa Cruz under the auspices of the Community Agroecology Network (www.CanUnite.org). The course was titled “The Transformation of Food Systems to Sustainability: The California Model.” Representing nine countries and diverse locations in the US ranging from Florida to Alaska and Maine to California, 32 participants and multiple presenters gathered together for an intensive introduction to how agroecology can be a vital and viable approach to redesigning today’s food systems. By presenting the transformation process as a series of transition levels (see JSA vol. 33, no. 1, pp. 1–2), food system change could be seen as not only being necessary, but plausible. With its grounding in ecology and ecosystem thinking, agroecology was cast as the action and change-oriented science that many of us believe is needed to avoid what has recently been called the pending “food crisis.” Rather than rely on more of the technologies that are being billed as the new green revolution, agroecology is an information intensive way of redesigning the food production process so that diversification, interactions, and resiliency all combine to create the emergent quality of sustainability. But it was also clear in the course that farmers alone cannot transform the entire food system. It will also take the full engagement of the folks at the other end of the food chain—the people who eat the food or use other agricultural products. After decades of food system policies and development focused on high yields, aggregation, and concentration, the growers and the eaters have become so isolated and separated that both have been exploited. Growers don’t know who is consuming their products and eaters have no idea who grows their food, how it was grown, or where it was grown. By reconnecting these two most important parts of the food system, the agroecology course showed how, by redeveloping a culture of sustainability, we can complete the transformation process needed to get us there (called Level 4 in the transition process). The course included participant observations on four local organic farms operating at different scales and integration in the food system. We also heard from major food system transformation projects such as the Roots of Change, the Food Commons,
