A comparison of three empirical models for assessing cropping options in a data-sparse environment, with reference to Laos and Cambodia

This report discusses three relatively simple modelling options that can be applied within a data-sparse environment, and presents them within the context of Laos and Cambodia. The capabilities and limitations of each model are comprehensively reviewed to provide the reader with an understanding of the options to reliably simulate crop processes that may be useful, for example, to influence farmer practice, decision making, and to improve and optimise resource use.
