 The issues of transboundary and cascading climatries are at the top of the agenda in the Africa Climate Summit. The CAHOSC, as we normally call it, is the one that provides guidance to the ministers of environment on what to consider and what to put emphasis on in the negotiations. Based on the science indicating that transboundary and cascading climatries are important in Africa, it's critical that we try to share the evidence that is available so that we are able to catalyse support and investment on addressing the transboundary and the cascading climatries.
