This International Climate Finance (ICF) funded programme will deliver an integrated package of projects to strengthen global knowledge and understanding of the interrelationship between the climate and biodiversity challenges. It will seek to inform the work of policy developers and development practitioners globally and help narrow the funding gap between current and required investment in natural solutions to climate change. It recognises that the scaling, and effectiveness, of natural solutions to the triple challenge of climate change, poverty and biodiversity loss (hereafter referred to as ‘natural solutions’) requires an investment in the primary evidence base needed to inform effective decisions, and drive innovation in the future. The proposed package of work is designed to meet both short and longer-term evidence needs, including to deliver a UNFCCC and CBD legacy, focusing on ensuring strategic, policy-relevant results and a global network of knowledge exchange and learning.
