The economic and political development of countries in the Belt and Road region is extremely uneven.Along with the progression of global warming,the natural environment,ecological environment,climate resources and water resources throughout the region will face new pressure brought by such significant changes.Moreover,drought,flood and other climate disasters are major threats to the sustainable development and major infrastructure construction in the Belt and Road region.At present,the Belt and Road Initiative has entered the substantive construction stage.Climate change and disaster risks occurring along the routes are related to the smooth implementation of the Belt and Road Initiative and investment security of the Asia Infrastructure Investment Bank (AIIB).In this context,the Department of Geosciences of the Chinese Academy of Sciences implemented the "Belt and Road region climate change issues" consultation project from June 2016 to June 2018.As part of the project systematic research was conducted on the facts of climate change throughout the region,as well as the prediction of future change,the possible impacts of climate change,and the potential risks brought on by climate change.Throughout this period,a number of analyses and studies have been carried out.After two years of implementation,the project team has completed four progress reports,including one general report and three sub-reports.The present paper briefly summarizes and introduces these achievements.
