He is also known for his efforts towards economic and social development in the Highlands. In 1907 he had been the principal speaker at a meeting of the Crofters' and Cottars' Association held in
Oban and spoke out about how depopulation was affecting the Highlands. He was co-founder of the Highland Development League. In 1936 he wrote a pamphlet entitled the “New Deal” in which he made suggestions towards a policy for development of the Highlands. This led the Highland Economic Committee to issue a report in November 1938 but Grant had concerns that many smallholders and crofters wouldn’t qualify for a ploughing scheme that the Government had proposed. Grant died in Ballachulish on 31 May 1945. ==Memorial==
