Riparian home-garden farming system are human landscapes that are sustainable, fulfilling the different pillars of socio-economic and environmental stability. This explorative study conducted in the 60 selected home-gardens in the left-right riparian banks of Chalakkudy river in Kerala, India casting the upper reaches and middle to lower reaches aimed to assess the crop diversity of tropical riparian home-gardens in terms of diversity index. Altogether 60 home-gardens were analysed and the
