The role of landscape in good design will be celebrated throughout the festival, known this year as the Welcoming City.
Among committee members involved with LFA 2010 (19 June to 4 July) are CABE Space director Sarah Gaventa and European Foundation for Landscape Architecture president Nigel Thorne.
The Landscape Institute's London branch, led by Shelley Mosco, is planning a series of events and Churchman Landscape Architects is involved with the bi-annual event for the first time this year.
Churchman senior landscape architect Jaime Uriarte explained: "We decided it would be good to get formally involved. It is about doing something more in the public eye, and we will do something quite creative and innovative."
Centrally curated by the Architecture Foundation, New London Architecture and RIBA London, the festival is run in partnership with bodies including the Royal Parks, CABE Space and London Metropolitan University.
There will be three hubs over the three weekends of the LFA - West End Hub (19-20 June), East End Hub (26-27 June) and Southbank and Bankside Hub (3-4 July).
The West End Hub is centred around Portland Place, Regent Street and the Royal Parks. It looks at an improved pedestrian route for Regent's Park and Regent Street.
The East End Hub, between Whitechapel and Stratford, will host High Street 2012, representing the last 6km of the London Olympic Marathon in 2012, as well as a wider streetscape and regeneration strategy.
The final weekend, the Southbank and Bankside Hub, will focus on the area between the River Thames and Elephant and Castle. It will include the Bankside Urban Forest, which will highlight projects to improve the public realm.
