Three dimensions of the benefits of using clonal rubber trees in smallholder plantations in Indonesia are defined and quantified: private benefits based on faster growth, more Imperata control, and higher latex yields; private (and social) benefits derived from a reduction in fire risk (resulting from more effective Imperata control); and social benefits associated with an increased level of carbon sequestration (reduction of atmospheric carbon dioxide). These benefits are compared with those obtainable from unselected (unimproved) seedlings. Previous research has focused on the private growth and yield benefits from using clonal rubber in the absence of fire risk (see chapter 14). Most of the emphasis in this chapter is on the social benefits resulting from the use of clones associated with fire risk reduction and enhanced carbon sequestration.
