The agriculture chapter covers a large number of binding rules, many of which are directly applicable. The proper application of these rules and their effective enforcement and control by an efficient public administration are essential for the functioning of the common agricultural policy (CAP). Running the CAP requires the setting up of management and quality systems such as a paying agency and the integrated administration and control system (IACS), and the capacity to implement rural development measures. Member States must be able to apply the EU legislation on direct farm support schemes and to implement the common market organisations for various agricultural products.
