The aim of the database is to give an overview of existing resources, tools and methods to promote crop diversification strategies (rotation, multiple cropping, intercropping) at different levels (including the value chain and territory levels). This version contains 143 resources. Each resource is described with a set of criteria: strategies used / described in the resource, purpose of the resource (what is an end-user doing with the resource), expected performances, area of validity, context of use, but also characteristics for use (cost, training, required time to collect data…). A toolbox was also designed to support end-users to navigate among this database and aims to help different type of end-users to identify interesting and adapted resources to foster crop diversification.
