For some time, climate change has intensified and exacerbated the environmental problems of the Mediterranean basin caused by the combined effects of changes in land use, increased pollution and biodiversity loss. In most impact domains, and in particular terrestrial ecosystems, current and future scenarios consistently reveal significant increased risks in the coming decades. In particular, warming is already 20% faster than the global average. Water resources will decrease significantly, especially in the south and east. The Mediterranean climate domain will extend to the north while the southern regions will become more arid. The risk of forest fires due to heat waves will also increase. The sustainable development policies of the Mediterranean countries must reduce these risks and consider adaptation options. However, they do not currently have the necessary information to do so, especially in the most vulnerable regions of the southern Mediterranean where systematic observation systems and impact modelling are less developed. Specific efforts are being made to compile existing scientific knowledge in different disciplines to better understand the risks involved. These efforts are coordinated by the Mediterranean Expert Network on Climate and Environmental Change (MedECC).
