The innovation we examine in this chapter is the adoption and partial abandonment of ginger by small-scale coffee growers in the mid-elevation mountain region in Kepahiang subdistrict (in Rejang Lebong district, Bengkulu province, South Sumatra). Coffee smallholders have always grown annual crops such as rice, maize, cabbage, and tobacco. These annual crops may be cultivated on fallows independently of coffee farms but are also widely intercropped with young coffee seedlings. In relatively densely populated mountain regions where the land is scarce, coffee farms are regularly replanted. During the first two years without any coffee returns, annual crops with a ready market, such as ginger, play a major role in funding the investment in replanting (chapter 16). The income from these crops also supplements the income drawn from coffee and contributes to food security. While the farming system remains based on a perennial crop, it is fairly broadly diversified. Why should adoption of this annual crop deserve a special chapter? Beyond the fact that we have qualitative data on that farming system for the period 1989 to 1998, the answer is that because of its many special features, ginger on family farms raises several major questions about the development of upland regions.
