註釋The need to determine whether current land management practices and agricultural systems are environmentally and economically sustainable has led to the development of a framework for assessment of sustainable land management (SLM). Indicators of SLM can be grouped into four categories: physical, agronomic, economic, and social. This report reviews some indicators of SLM and assesses selected indicators using 1991 Census of Agriculture data. The indicators were selected on the basis of criteria from the literature as well as availability of data. Examples of indicators having the potential for use in SLM are cropping intensity, nutrient budgets, yield variability, windbreak density, crop influence on soil quality, summerfallow trends, gross margin with and without government subsidies, and debt load.
