The three-year Climate Challenge Programme Malawi (CCPM) focuses on delivering long-term change and improving people's access to food, water and energy.
The programme will be delivered by Scottish Catholic International Aid Fund (SCIAF) and will work with local people to identify the climate challenges they face, with a particular focus on helping the most vulnerable, including women and girls, and promoting human rights.
SCIAF director Alistair Dutton said: "Millions of the poorest people in the world are suffering terribly from climate change, despite them having done least to cause the problem.
"Increasingly erratic weather makes it incredibly hard for small scale farmers to know when to plant their seeds, while more frequent and severe floods, drought and storms can wipe out their crops overnight, leaving them hungry and forced to leave their homes."
He added that the programme will help vulnerable communities in southern Malawi cope with the climate challenges they face by increasing the food, water and clean energy they have.
According to a recent Trócaire study 90 per cent of Malawians depend on rain-fed water agriculture and a single harvest each year.
Scotland Environment Secretary Roseanna Cunningham announced the funding ahead of attending an international conference at the Vatican which is aimed at addressing the urgent ecological and social challenges facing the world.
