They provided a vital line of defence in the Second World War but iconic forts in the Thames Estuary have fallen into disrepair. There are fears the Redsand Forts, which sit in the water between Kent and Essex, could disappear altogether if funding isn't found to repair them. More than £3 million is needed to restore them. Tom Savvides joined a boat trip to the site, to see the historic structures. He talks to David Phillips from Project Redsand and boat trip organiser Alan Harmer.
You don't usually associate the Thames Estuary, once heavily polluted, with a thriving seal population. But that's exactly what's happened. It's estimated that more than two and a half thousand seals have made the waterways along the Kent and Essex coasts their home. Now, conservationists have started patrols as part of an annual survey to count and monitor the mammals' development. Tom Savvides talks to Anna Cucknell from the Zoological Society of London.
The final turbines are being installed at an offshore windfarm in the Thames Estuary. Phase two of the Kentish Flats scheme off the coast near Whitstable is almost complete. A total of forty five wind turbines could power seventy five thousand homes each year. Tom Savvides talks to project director Matthew Green and Gunnar Groebler from the company Vattenfall.
While many believe another runway is needed in our region, few want it in their back yard. Although the expansion of Heathrow could create thousands more jobs, it would also bring more aircraft noise and pollution. And in some cases whole communities could be wiped out.
Chris Maughan has been finding out what the expansion of Heathrow would mean for those living under the flightpath.
The Travel expert Simon Calder gives his opinion on today's Davies report on airport expansion.
Plans for a Thames Estuary airport were first proposed in the 1970s. But the idea was given new impetus five years ago by the London Mayor, Boris Johnson who proposed an airport off the Isle of Sheppey.
The architect Lord Foster suggested a hub airport on the Isle of Grain and there's even a proposal to build at Goodwin Sands, near Dover.
Our reporter, John Ryall has been in north Kent to find out what people there think.
The Davies report into the future of aviation in the South highlights that airport expansion is desperately needed in the south east - but few people want a new runway in their backyard. While growth could create more jobs, it would also bring more aircraft noise and pollution.
Gatwick Airport still has a lot of spare capacity. But, is a new runway even necessary? Our correspondent Malcolm Shaw has been looking at the arguments.
The Davies report into plans for the future expansion of airports in the South has not included a shortlisting for a potential Thames Estuary airport. However the option has not been completely ruled out.
If an airport were to be built in the Thames Estuary it would impact on thousands of people in North Kent. For reaction from Westminster here's our political correspondent Phil Hornby.
Natalie Bennett, the Leader of the Green Party, tells ITV Meridian that there is no need for any airport development in the south east. And she repeats her party's belief that an estuary airport option is the worst of all possible worlds. She's been talking to our reporter Kevin Harrison.
