Campaign booklet Why Invest in Landscape? marks the beginning of a year-long agenda. The institute will increase its lobbying of central Government and local authorities as well as parish councils, voluntary agencies, developers and community groups.
It will also seek dialogue with the local enterprise partnerships that are set to assume many of the activities of England's regional development agencies once they are abolished in March 2012.
The campaign publication highlights six examples from England, Wales and Scotland of how investment in landscape has benefited local economies and communities.
Institute president Jo Watkins said: "High streets, squares, parks and other public spaces should be special places. Getting them right is the best investment you can make. Getting them wrong often has people voting with their feet."
He added: "When landscape is placed at the heart of the development process, developers profit while businesses and communities reap the economic benefits."
As part of the campaign, the institute will run a series of seminars at the Ecobuild Conference in London's Excel Centre on 2 March and Street Design in Birmingham on 30 March.
