tThe cultivation of crops in a given area is highly dependent of climatic conditions. Assessment of howthe climate is favorable is highly useful for planners, land managers, farmers and plant breeders who canpropose and apply adaptation strategies to improve agricultural potentialities. The aim of this study wasto develop an assessment method for crop-climate suitability that was generic enough to be applied to awide range of issues and crops. The method proposed is based on agroclimatic indicators that are calcu-lated over phenological periods (ecoclimatic indicators). These indicators are highly relevant since theyprovide accurate information about the effect of climate on particular plant processes and cultural prac-tices that take place during specific phenological periods. Three case studies were performed in order toillustrate the potentialities of the method. They concern annual (maize and wheat) and perennial (grape)crops and focus on the study of climate suitability in terms of the following criteria: ecophysiological,days available to carry out cultural practices, and harvest quality. The analysis of the results revealed boththe advantages and limitations of the method. The method is general and flexible enough to be appliedto a wide range of issues even if an expert assessment is initially needed to build the analysis framework.The limited number of input data makes it possible to use it to explore future possibilities for agriculturein many areas. The access to intermediate information through elementary ecoclimatic indicators allowsusers to propose targeted adaptations when climate suitability is not satisfactory.
