Sense and Sustainability: Sustainability as an Objective in International Agricultural Research
讨论如何将可持续性作为评估农业研究的标准，分析应用该标准的困难，并提出对国际农业研究的启示，包括测量可持续性和外部性的方法。
Abstract This paper first discusses how to use sustainability as a criterion by which to evaluate agricultural research, then illustrates the difficulties inherent in applying the criterion and finally draws implications for international agricultural research. Seven propositions relating to sustainability are stated. Agricultural researchers are urged to (a) recognize the importance of the sustainability of agricultural systems. (b) devise appropriate ways to measure sustainability, (c) empirically examine the sustainability of some well‐defined cropping or farming systems, (d) define the externalities that exist in such systems, and (e) develop methods to measure those externalities.
