Drought dynamics reveals a time gap between the onset of a drought event and the management of the drought emergency, but often this gap is too wide to effectively reduce the impacts Drought information is frequently scattered and not enough integrated to support diverse users' needs.

Abstract
Drought dynamics reveals a time gap between the onset of a drought event and the management of the drought emergency, but often this gap is too wide to effectively reduce the impacts Drought information is frequently scattered and not enough integrated to support diverse users' needs. Therefore, there is a need to increase preparedness through proactive solutions providing timely and simple information. In other words, an integrated Drought Climate Service could fill the gap, as drought monitoring is key to increase a better resilience reducing the impacts of drought events. To be effective, a Climate Service should respond to different priorities and users' needs and have a set of main requirements: information continuously updated and timely delivered, expandable platform and on-demand services, products adequate to the diverse users' competencies and technical skills. Following this approach, the Institute of Biometeorology of the National Research Council, in collaboration with the LaMMA Consortium, developed a system to provide a semi-automatic, detailed, timely and comprehensive operational service.
