对土地退化的判断不能脱离其空间、时间、经济、环境和文化背景。因此，评价几乎是无限可变的，非常动态。这些意见在两个方面进行了审查，首先在两个案例研究。其中一个来自黎凡特南部，利用了一个漫长而有据可查的环境评估历史，该历史在不同社区之间存在很大差异。另一份来自当代尼日尔，显示了村民之间更细微的差异。第二，动态和多方面的未来（可持续性）的评估是从尼日尔的同一个案例研究的数据说明。在这一更广泛的背景下，多样性和动态性在很大程度上是环境或社会未来模式选择的结果。大规模和更精细的退化评估之间通常存在的正差异被称为[社会交付率]。简化的评价制度可能对分配是必要的，但如果这里的论点被接受，就需要非常谨慎地对待。版权所有© 2002年约翰威利父子有限公司。
Land degradation cannot be judged independently of its spatial, temporal, economic, environmental and cultural context. Evaluations are therefore almost infinitely variable and very dynamic. These observations are examined in two contexts, first in two case studies. One, from the southern Levant, makes use of a long and well‐documented history of environmental assessment that varied greatly between communities. The other, from contemporary Niger, shows finer scale differences among villagers. Second, the dynamic and multiple assessment of futures (sustainability) is illustrated with data from the same case study in Niger. In this wider context, multiplicity and dynamicity are largely a consequence of the choice of model of the environmental or social future. The usually positive difference between large‐scale and finer scale assessments of degradation is dubbed the [social delivery ratio]. Simplified systems of evaluation may be necessary for allocation, but they need to be treated with great caution if the argument here is accepted. Copyright © 2002 John Wiley & Sons, Ltd.
