    Important agronomic characteristics of common root and tuber crop production systems in the tropics are indicated for crops including cassava, yam, sweet potato, and edible aroids. Brief comments are also included on aspects that help correctly interpret the information obtained during the characterization process. The general context of agricultural production is analyzed, and within this context, the particular case of root crops, where the process of transformation into derived products, at both farm and regional levels, may condition the agronomic practices used.

    Using the farm as unit of analysis, diagnosis processes aimed at improving production systems are reviewed. Within a country, diagnosis should be conducted at different hierarchical levels: local (interaction between the production system and the input distribution sector, the marketing sector, possible forms of processing, and consumption characteristics); regional (appropriate selection of target site); and national (development trends and governmental policies at the macroeconomic and sectorial levels).
