Every year, the Peacebuilding Commission (PBC) holds an annual session that brings together UN and Member State colleagues to focus on timely and key peacebuilding challenges and opportunities. This year's meeting, held on 4 December, focused on peacebuilding in Africa, particularly in the Sahel, Lake Chad Basin and Mano River Union regions. Key issues in focus included the transborder threats of armed extremism, underdevelopment, climate change and gender-based violence.
