This week, delegates at the (COP15) in Montreal pursued their negotiations which started on 7 December 2022. In the first week, delegates approved about 20 decisions. Many subjects were covered including decisions relating to the facilitation of the full and effective participation of Indigenous Peoples and local communities in all of the work of the .

[ 1] As pointed out by the United Nations Environment Programme (UNEP), adoption of a bold global biodiversity framework that addresses the key drivers of nature loss is needed to secure our own health and well-being alongside that of the planet. 
Many events have been taking place in the past days. For example, on 13 December, the United Nations recognized that are restoring the natural world. The initiatives were declared World Restoration Flagships and are eligible to receive UN-backed promotion, advice or funding.

On the subject of biodiversity, this week’s Map of the Week focuses on coralligenous outcrops and mäerl beds which are the result of the building activities of algal and animal constructors, counterbalanced by physical, as well as biological, eroding processes. Because of their extent, biodiversity and production, coralligenous and mäerl habitats rank among the most important ecosystems in the Mediterranean Sea, and they are considered of great significance both for fisheries and natural carbon sequestration.
