The overall objective of creating the National Adaptation Geo-Information System (NAGiS) was to develop a multipurpose geo-information system that can facilitate the policy-making, strategy-building and decision-making processes related to the impact assessment of climate change and founding necessary adaptation measures in Hungary. It was designed to help the elaboration of the country’s Adaptation Strategy, a part of the second National Climate Change Strategy.


The legal predecessor of the Hungarian Mining and Geological Service (MBFSZ) established the NAGiS with the support of the European Economic Area (EEA) Funds, between 201320–16. The system was created with the cooperation of leading Hungarian climate change research institutes. The NAGiS research processes were built on the Climate Impact and Vulnerability Assessment Scheme (CIVAS) model. Climatological research was based on the CarpatClim-Hu observational database and on projection results of the ALADIN-Climate and the RegCM regional climate models for the 1961–1990, the 2021–2050 and the 2071–2100 time windows. The further development of NAGiS is implemented between 2016–2019, with the support of the Environmental and Energy Efficiency Operative Programme of Hungary. The main goals of this second development phase include the creation of online tools for policy and development policy planning; as well as making web-based tools to assist in planning municipal, district and county self-governments.


The main parts of the NAGiS are a map-visualization system (650 layers); a database containing the calculation results based on modelling (the GeoDat with 910 data layers, with 10 x 10 km resolution); and a meta-database to help finding relevant data. The GeoDat includes calculation results (exposure, sensitivity, expected impact, adaptability, vulnerability). Data layers on 16 topics are available for Hungary at the portal. Some of the topics are: impacts of climate change on shallow groundwater, risk of flash floods, vulnerability of natural habitats; impacts of climate change on agricultural biomass production and woodland management; impacts of heatwaves on human health.


The National Adaptation Geo-information System (NAGiS) may be used by national, regional, and local decision makers and stakeholders. It provides information on the climate status of the country, on the impacts of strategic risks connected to climate change, and on adaptation possibilities, based on indicators, analyses, and impact studies. NAGiS has been used on many occasions in Hungary, since 2016: for the preparation of the second National Climate Change Strategy, the design of climate strategies of counties, and other local design and research projects.
