Abstract

High latitude agriculture is rainfed. Climate change could, however, increase water deficiency and initiate a call for development of irrigation systems as a part of field water management systems. This study aimed to develop a basic understanding about the current state of irrigation potential according to region by monitoring proximity of fields to waterways and characterizing their general conditions. One third of Finnish fields are in direct contact with a shoreline of an inland waterway. This coupled with Finland being water-rich country may improve adaptive capacity to cope with the potentially harmful impacts of climate change in the future. However, there are marked differences between regions in access to water resources. Findings of this survey will serve as background information needed to assess future needs for introduction of irrigation and to evaluate the opportunities to close yield gaps and improve yield stability through irrigation.
