Improvements in the sustainability of agricultural production depend essentially on advances in the efficient use of nitrogen. Precision farming promises solutions in this respect. Variable rate technologies allow the right quantities of fertilizer to be applied at the right place. This helps to both maintain yields and avoid nitrogen losses. However, these technologies are still not widely adopted, especially in small-scale farming systems. Recent developments in sensing technologies, like drones or satellites, open up new opportunities for variable rate technologies.

This evaluation seeks to understand the impact which certain measures of the CAP have had on reducing GHG emissions, agriculture’s vulnerability to climate change and its ability to provide adaptation and mitigation services to society. Most of the CAP measures analysed do not have climate action as their intended purpose but may have it as a secondary purpose. Some, such as those which sustain certain forms of agricultural production responsible for emissions, exist for economic, social and sometimes other environmental reasons.
