In parallel of the preparation of the 21st session of the Conference of the Parties the United Nations Framework Convention on Climate Change (COP 21 – UNFCCC, 2015), it was decided to build a network of scientists and a mechanism in support of a regional science-policy interface for climatic and other environmental changes across the Mediterranean. The aim of MedECC is to provide sound scientific information about environmental issues of concern for the Mediterranean region. Specific objectives are : ▪ To gather the scientific community working on climate change and its impacts in the whole Mediterranean basin. This includes building a bridge between existing research structures and programs and facilitating data-sharing through existing or new platforms. ▪ To update and consolidate the best scientific knowledge about climate and environmental change in the Mediterranean basin and render it accessible to policy-makers, key stakeholders and citizens. ▪ To contribute to future IPCC, IPBES or related assessments in the Mediterranean basin. ▪ To bridge the gap between research and decision-making, contributing to the improvement of policies at national, regional, and local level by providing consolidated scientific assessments on particular issues and by responding to requests by decision-makers. ▪ To identify gaps in the current research on climate change and its impacts in the Mediterranean and interact with funding agencies for the development of new research programs to fill these gaps. ▪ To help building the capacity of scientists from Southern and Eastern Mediterranean Countries (SEMCs) at the international level and standards; encouraging training, research and development efforts in these countries.
