APAT – Climate change impacts in Italy and adaptation policies

The research project aims to assess the socio-economic impacts of climate change and analyse the costs/benefits of adaptation strategies in specific areas at risk in Italy

6 months from 01/06/2007 to 01/11/2007

General aims

The research project aim was to assess the socio-economic impacts of climate change and analyse the costs / benefits of adaptation strategies in specific areas at risk in Italy, particularly in areas at (i) deglaciation risk , (ii) hydrogeological risk, ( iii) desertification risk and (iv) in the areas at risk of coastal erosion / flooding, placing particular emphasis on the methodologies to be used for a proper economic evaluation.

Thanks to this information, the project has drafted an assessment of the overall national macroeconomic impacts, with a particular focus on changes in international trade flows brought by climate change.


Drafting of eight scientific reports on socio-economic impacts of climate change and on related adaptation strategies, in collaboration with APAT (Agenzia per la Protezione dell’Ambiente e per i Servizi Tecnici – now ISPRA), within the framework of the National Conference on Climate Change (NCCC), sponsored by the Ministry for the Environment, Land and Sea and organized by APAT on 12-13 September 2007.

Expected results

The results of the study have been collected in different scientific reports on the evaluation of the impacts of climate change and were presented in both the preparatory workshops to the National Conference and in the second day of the plenary of the NCCC:

  • Contextualisation and application to the Italian territory of the IPCC scenarios with regard to socio-economic vulnerability of areas at deglaciation risk, hydrogeological risk, desertification risk and coastal erosion risk;
  • Quantitative evaluation of the costs of inaction in areas at risk due to the impacts of climate change on water resources, biodiversity, agriculture, productive activities and health;
  • Quantitative evaluation of the costs of adaptation to climate change with a dynamic analysis of adaptive capacity of different socio-economic systems, disaggregated by sector and areas at risk on a national scale;
  • Economic assessment of impacts in terms of general economic equilibrium (ie, taking into account the effects of structural changes induced by climate change and adaptation measures);
  • Definition of an approach for cost benefit analysis of the interventions needed to implement adapatation policies.
