Governments, civil society, the private sector, governments, civil society and individuals in Africa are making critical investment decisions about the near-term development of their nations and localities. The impacts of climate change can determine whether development plans can achieve the desired benefits for society. The impact thereof will be significant and far-reaching. Mainstreaming climate risk management and adaptation into development planning is therefore essential if desired outcomes are to be realised and sustained. The key findings highlighted in this policy brief from the FCFA Zambia pilot case study examines how current and future climate science can enable development and humanitarian policy, planning and implementation that is climate smart and robust to projected changes in the medium to long term. The findings are based on activities undertaken by the Red Cross/Red Crescent Climate Centre between February and October 2014, in close collaboration with the Met Office Hadley Centre and the Zambia Red Cross Society.
