This scoping study provides information on sources of financing and financial tools and instruments for addressing HMCCC. It will explore where such financing comes from and detail the innovative financing solutions that are currently being implemented, piloted and suggested. The study pays particular attention to the gender transformative power of the tools and instruments presented and the extent to which the COVID-19 pandemic is affecting financing flows and options. Human mobility is a catch-all term encompassing forced displacement, migration and relocation. The way it is addressed is therefore context dependent, and the normative point of departure of this scoping study is that the sources, tools and instruments should serve the wellbeing of people affected by the different types of mobility. While the study is intended for a general audience, it will be especially useful for governments facing pressing HMCCC challenges as it will help them identify concrete instruments and methods for financing measures to address HMCCC and relevant implementing agencies and institutions capable of carrying them out. While the authors recognise that HMCCC is happening all over the world, this study focuses on developing countries that are particularly vulnerable to the impacts of climate change. The second section of the introduction provides background information explaining why there is an urgent need to better understand financing related to HMCCC. The next chapter gives a general overview of the different sources of HMCCC financing, followed by a description of financing tools and instruments. The penultimate chapter discusses the potential impacts of COVID-19 on sources of financing and the implementation of the tools and instruments, and the final chapter sets out conclusions and recommendations going forward.
