A charity set up by Save the Children UK to build a network of organisations that could respond to emergencies is to merge back into Save in order to secure its future.
The Humanitarian Leadership Academy was created by Save in 2015 to establish an international network of partners that could respond quickly to emergencies in disaster-prone countries.
Although the academy was created as a separate charity, it is based in the same London office as Save and shares some back-office functions, including IT and finance.
The academy's income fell from £6.4m to £5.9m in the financial year ending 31 December 2018.
A spokeswoman for the organisation described the funding climate as "tricky" and said becoming part of Save would help it to continue its work.
Saba Al Mubaslat, chief executive of the academy, said in a statement: "The merger with Save the Children UK is the next phase in our journey.
"It secures our future and will help us to gain strength, reach more people and save more lives."
The academy, which employs 17 staff, provides free learning through its digital platform, Kaya.
It also provides paid-for services in organisational learning and development, which it hoped would enable it to become a sustainable social enterprise after the expiry of initial funding from the Department for International Development, philanthropists and the corporate sector.
It is yet to be decided whether the board will be disbanded once the merger is completed on 30 April.
The spokeswoman said all staff would transfer to Save, although a decision on Al Mubaslat's new role has not yet been taken.
