As a part of the famine relief work, Buckingham had commenced the construction of a navigation channel between Madras city and the northern part of the Madras Presidency so that transportation of supplies to the interior in cases of emergency would be easy. More than 715,000 people were employed as labourers in Madras to assist with the relief work. Opened in 1878, this canal was named after Buckingham as Buckingham Canal. Buckingham Street in Penang, Malaysia was also named after him by the Tamil labourers who were brought there during the British colonial period.
