This document provides an introduction to the city of Gandhinagar, India. It discusses how Gandhinagar was planned and developed as a new capital city for the state of Gujarat in the 1960s on a greenfield site. The city was planned with a 1000m x 750m grid layout and divided into residential and commercial sectors. However, bureaucratic control over land development led to underdevelopment and vacant land. The document examines proposals to transform Gandhinagar by developing the vacant land along the Sabarmati River into productive landscapes and ecological spaces that establish Gandhinagar as the "productive capital" or "biodiversity capital".
