Two-day Field-Trips will take place on 21 and 22 May 2020. A selection of Field-Trips will focus on delimited regions within continental and insular Portugal, a country that, for its small size, has surprisingly a high hydrogeological diversity. Its organization and conduction will be delegated by the Organizing Committee to researchers from Portuguese Academies. A detailed Field-Guide will be produced and delivered to participants. Each Field-Trip is expected to include no more than 20-25 persons, travelling in touristic minibuses, and air travels to/from Madeira and Azores. Field-Trips are intended to provide delegates an exciting and rich direct experience with relevant aspects on the natural and cultural heritage of Portugal, also as Geoparks, aspiring Geoparks and/or Environmentally Protected Areas, with a focus in a selection of Groundwater and Geoethics hotspots, allowing widening personal experiences, networking and the appreciation of the ethical bases that support the work of researchers and professionals in Groundwater and in Natural Resources Management. Enrolment is an option in the registration process. Accompanying persons may enrol as well. The list of Field-Trips together with a short presentation will be posted at the Congress website in time for the beginning of the registration process.
