Land where lush, waving grasses flourished is now eroded and only sparsely covered with plants. One consequence, says farmer and rural public policy expert Michael Bowm
3、an of Wray, Colorado, is that “hundreds of small communities whose economies relied on healthy grassland are withering with the grass.“ 在大多数人眼中,西部的大草原依然能反映美国的立国之本:以草原为起点的广袤平原,依托落基山脉海拔升高,这里是牛群和牛仔的家乡。如此在人们脑海中难以磨灭的画面却掩盖了一些事实,因为过度放牧已经使这个国家的牧场退化。曾经丰美茂盛的草地如今已遭破坏,地面鲜有植物生长。科罗拉多州雷县的农村公共政策专家、农场主迈克尔鲍曼表示,由此而生的一

And have embarked on doing so by increasing the density of livestock.许多牧场主、保守人士和投资者都决意重新缔造这块土地的

Allan Savory, who developed Holistic Management as a researcher and farmer in Southern Africa, saw the conne

The dynamic is as follows: the animal chews the grass so as to stimulate plant and root growth, and allow sunlight to get through to the growth points, then moves on in a herd either (in a leisurely way) to find fresher grass or (with a poun

He found that when domestic livestock are managed to replicate this behavior on degraded lands, the grasses come back: the deep-rooted plants enrich and aerate the soil and the hoof movements chip away at hardened earth so that seeds can germinate and grow and wa

11、青草就会再生长出来:那些深深植根于大地的植物使土壤肥沃又透气,家畜蹄踩会逐渐松动坚实的土地,地下的种子就能生长发芽,水也可以渗入地底。 Rich, aerated soil is productive, retains water, and, highly significant in environmental terms, is a carbon sink. “Healthy grasslands represents the ecosystem with the highest potential for carbon sequestration of any on the planet
12、,“ says Steven Apfelbaum, Founder/Chairman of Applied Ecological Services, Inc., a landscape restoration company based in Brodhead, Wisconsin. He notes that grasslands cover more than 45% of the U.S., a proportion fairly consistent throughout the world. This has important implications for reducing a
13、tmospheric CO2. Plus, soil carbon plays a vital role in sustaining water supplies, which are perilously threatened in much of the West. “Every one percent increase in soil carbon holds an additional 60,000 gallons of water per acre,“ says Apfelbaum. “Water infiltrates the ground and replenishes grou

18、derstood as a carbon cycle dysfunction: too much carbon is up in the air rather than in the soil, where it lends fertility (33% of soil organic matter is carbon). Similarly, floods and droughts are symptoms of a carbon cycle gone wrong: when soil is compacted or eroded, rain evaporates or runs off.
19、This June, Allan Savory won the Buckminster Fuller Challenge for “Operation Hope,“ a program in Zimbabwe that uses livestock and Holistic Management to fight poverty and food scarcity through restoring soil, water and biodiversity to degraded lands. 从这个角度来看,大气中的二氧化碳过多可以被理解为碳循环功能障碍:太多的碳不在土壤里,而在空气中,这剥

Nancy Ranney of Ranney Ranch in Corona, New Mexico, family-run since 1968, says that since introducing Holistic Management practices in 2002, feed costs have plummeted to one-fifth of what they were, fuel and labor costs have dropped 50% and 30% respectively, and the land is mo

While the pasture had been dominated by one type of grass, blue grama, “within three years we had 25 native grasses,“ she says. “The seeds were dormant in the soil and reappeared.
23、“ This attests to increased biodiversity, which reflects a healthier ecosystem. 与此同时,在西部牧场,农场主使用整体管理法削减成本,提高盈利能力。从 1968 年起,新墨西哥州科罗纳的南希兰尼一家就开始经营兰尼牧场。兰尼说,牧场 2002 年引入整体管理措施,饲料成本已降至此前的 1/5,燃料和劳动力成本减少了 50%和 30%,土地对干旱的适应性变得更强。她也提到,这家 18,000 英亩的中型牧场更为健康。尽管现在牧场饲草品种主要是蓝色格兰马草,但“三年内我们就会有 25 种本地草种, ”她说, “正在土壤中休
24、眠的种子会重新发芽。 ”这证明了生物多样性有所增加,反映出这个生态系统比以往更加健康。 For Ranney, these changes not only made economic sense, but also spoke to family priorities. “We all feel this land was entrusted to us by our parents and grandparents, and we care about the integrity of the land,“ she says. “Were also concerned about glob

29、研究所创始人兼所长约翰富勒顿在内的一些投资人成立了草原责任有限公司,在南达科他州购买了两个牧场,目前附属于雪柏利研究所,由首席执行官吉姆豪威尔负责运作。在试行季节,草原公司已经提高了土地的生产力:动物可食用饲草量增加了 20%以上,不再像过去无序放牧时那样杂草丛生。这意味着土地可以承载更多的牛群。富勒顿说:“土地的生态质量有所提高之后,盈利将随之而来。 ”他还表示:“ 我们不仅要努力跟进了解生态和经济变化,还要随时关注社会进步。如此一来,我们就会拥有以农村土地为依托的经济,它将再次蓬勃发展。 ” Grasslands, LLC is also exploring means to moneti
