Small-holder farmers in 12 countries were surveyed about changes made to their practices and the reasons for those changes. Weather information was found to be significantly associated with changes in 3 of the 4 regions surveyed. The reasons for changes varied across regions and included adopting improved varieties, adjusting timing, improving land management, and using more fertilizer. While most climate adaptation research has focused on temperate areas, the survey found major impacts in tropical locations as well. The document concludes that climate information is one factor among many that influence farmers' decisions to change practices and that local context is essential for developing effective climate adaptation and mitigation policies.
