The policies integration process between agriculture and environment in Europe fosters the development of agricultural practices that preserve the environment and safeguard the countryside.Various EU directives and programmes, such as the Rural Development Programme, the Water Framework Directive and others, set strategic guidelines for the Common Monitoring and Evaluation Framework by defining objectives and indicators to evaluate the progress and achievement in environmental protection measures. The AgriEnvironment Core Information Service (AgriEnv CIS) contribute to the improvement of the timely and accurate monitoring of agricultural land use state and its changes at European, national and regional levels by providing common methodologies and indicators to monitor the impact of the programmes and their measures. This study describes the background, the materials and the methods use as well as the definition, context, policy drivers, approaches and preliminary results for the elaboration of an agri-environmental indicator named “agri-environmental measures effectiveness” in the framework of the GMES-Geoland2 project.
