Environment Minister Phil Woolas told BBC Radio 4's Today programme: "The insurance companies, very reasonably say that it's necessary to have a long-term strategy.
"We're looking at, of course, coastal flooding as well as river flooding and surface-water flooding, to ensure that the increased investment that we have - and we have increased investment in flood defences in this country quite substantially - are sustained in the long term."
Climate change predictions had changed, with information from scientists suggesting that "extreme weather conditions are going to increase in the decades to come - and that requires a long-term strategy as well", Mr Woolas added.
The ABI's Justin Jacobs said: "What we've agreed with the government is that if they can make sure as many people as possible are protected, we'll be able to make sure we can offer affordable insurance to all our customers who want it.
"The pressure remains on the government because they must deliver those defences to people in order make sure we can offer affordable insurance."
The ABI had been highly critical of the amount of money ministers had pledged for flood defence work.
It said 517,000 homes were at significant risk of being flooded.
Previously, the ABI's director general Stephen Hadrill had accused the government of "completely failing to grasp the importance of improving Britain's flood defences in the wake of the devastating floods across the UK".
During 2007, flooding cost the ABI's members £3bn in claims.
Insurers were confronted with four years' worth of claims in just two months, with 180,000 claims for homes, businesses and cars.
