In this literature study, conducted at the International Council for Research in Agroforestry, Nairobi, Kenya, an overview is presented of both methods of land description and assessments of land potential. The first part of the paper contains reviews of methods employed to describe and map climate, landforms, soils and vegetation, and to assess land potential from these factors. It discusses methods of agroclimatic analysis, climatic indices, and methods for analysis of the effect of soils on land productivity. The second part covers methods to describe and map the physical environments as a whole, including the land systems approach and agro-ecological surveys. Comments are offered on the value of different methods as a means to characterize, classify, map and evaluate environments to assist international cooperation in research and use of agro-ecological methods. KEYWORDS: TROPAG | Environmental Relationships | agricultural potential | land classification | agro ecosystem | surveys | systems analysis.
