抗旱作物 e.g.Drought-resistantcropsneedlesswater.在水资源匮乏的世界中重新思考灌溉1

效率是全球最常追求、也最常被误解的公共政策目标之一。为了缓解气候变化，我们需要提高能源效率。为了降低供应链成本，我们需要提高运输效率。为了避免全球约70%的淡水取用量用于农业所导致的水资源危机，我们需要更高的灌溉效率。2然而，削减成本和资源，或彻底改革看似低效的系统，往往并不能改善结果。效率措施非但不能改善目标系统，反而可能削弱其韧性及其提供服务的能力。3为什么这对我们的粮食系统很重要？随着水资源日益匮乏以及人类对淡水生态系统的影响，在限制水资源使用的同时增加并维持粮食生产是一项紧迫的挑战。对此挑战的一个基本应对措施是，采用更高效的灌溉技术，在田间层面以相同或更少的灌溉用水量维持或提高农业产量，从而提高“单位水产量”比率（即，实际用于作物生长的水量，而非在输送过程中损失、灌溉杂草或蒸发的水量）。这至关重要，因为灌溉农田生产了世界上大部分的粮食。4与传统的通过地面漫灌分布水资源的灌溉方式（通常称为地表灌溉）相比，滴灌等高效灌溉技术使用加压系统，允许水通过带有灌水器的窄管缓慢滴入植物根部。滴灌技术通常能确保从水源抽取的大部分水到达作物，而地表水系统的效率则要低得多。这些效率提升在从美国西部到智利北部、从印度西北部到摩洛哥的干旱地区尤其具有吸引力。5政策制定者希望引进高科技灌溉技术能在农业中节约用水，从而将水“释放”给其他用户并用于维持生态系统可持续性。然而，越来越多的证据表明，高科技灌溉本身很少能带来预期的节水效果。事实上，正如杰文斯悖论所警示的那样，它似乎导致了相反的效果。配备高科技灌溉技术的农民用水更多，而非更少，整个流域的水资源可用性往往趋于下降。研究人员将此称为“灌溉效率悖论”。一些农民利用“节约”的水扩大灌溉面积，导致随后的土地转换和栖息地丧失；另一些农民则通过在同一块土地上一年内种植更多作物来提高种植强度；还有一些农民转而种植更耗水的作物，例如从高粱改种水稻。在农场层面更高效地施用雨水还会减少回流——即灌溉后从田间流走或渗入地下、最终汇入河流和含水层并因此可供下游用户和生态系统使用的水量。6灌溉效率悖论在水资源匮乏的世界尤其危险，原因如下：首先，它会破坏淡水生态系统的韧性。随着回流减少，可用于向下游流动以帮助鱼类繁殖和迁徙、促进鸟类繁殖或支持湿地的水量也会减少。其次，水资源可用性模式的改变可能破坏依赖同一资源的其他用户的生计。最后，高效技术使农民能够转向种植耗水量大的作物，因此当下一场干旱来临时——因为干旱总会到来——造成的损害甚至更大。这些技术非但没有促进对干旱和缺水条件的适应，反而可能通过引导农民放弃抗旱作物，从而增加他们面对未来更长干旱的脆弱性，这矛盾地助长了“适应不良”。7为了减少农业用水，我们需要的不仅仅是高科技的高效灌溉技术。仅靠技术的灌溉效率是虚假的效率。全球经验表明，投资滴灌系统只有在与其他干预措施相结合时，才能“节约”用水，例如限制取水量（即“用水上限”）和改进水资源监测。当向更高效灌溉技术的转变伴随着对灌溉取水和抽水的严格限制和控制时，它有助于遏制用水量的进一步增加。并且，当使用改进的数据和监测来跟踪农业系统的水资源储量、流量和用量时——这被称为水核算——我们就能更好地量化干预措施对用水量的影响。水核算需要扭转实地监测站数量减少的趋势，并利用对地观测和机器学习进步的潜力。8最终，要获得灌溉效率的益处，需要同时协调技术、制度和政治层面的干预措施。它还需要我们在缺水的背景下重新思考灌溉：从将灌溉效率视为仅靠技术就能实现的目标，转变为将其视为只有通过将技术与水资源监测、监管以及对农民需求和行为的更深入理解相平衡才能实现的目标。GlobalunderstandingReadthepassageandcompletethetable.AcommonproblemofefficiencymeasuresWeakeningthe1_____________________todeliverservicesUrgentchallengeinagriculture
