This chapter rejuvenates the promising but lost field of environmental gerontology. Environmental gerontology threatened to disappear after the death of its initiator, Powell Lawton. The chapter reviews recent developments and problems in these approaches, and shows how the sociocultural perspective presented here may offer a satisfying way to pursue these efforts. The first section comes back to the core concepts of spaces, places and affordances. The next one proposes a dialogue with two propositions made by Lawton: first, the importance of an ideographic approach to environments of ageing, to which we have proposed a regional case study. Second, Lawton made a typology of modes of housing for older persons, calling for intermediary ones; I propose a revised typology. Finally, I integrate our findings in terms of human development together with an ecological understanding of ageing, thus sketching a more complete psychology of ageing in a changing environment.
