Domestication potential and marketing of Canarium indicum nuts in the Pacific: 1. A literature review

Canarium indicum is an indigenous tree of the lowland forests of Melanesia (Papua New Guinea, Solomon Islands, Vanuatu) and parts of Indonesia producing edible nuts, commercial timber and some minor products. For thousands of years the nuts have been culturally important and a traditional food. Since the early 1990s there have been a number of projects aimed at the wider commercialization of the species, with mixed success. This review evaluates the biophysical and socio-economic literature and suggests how the domestication and commercialization processes could be taken forwards to improve the livelihoods of rural households in Melanesia. Many of the issues facing the domestication and commercialization of C. indicum nuts as an Agroforestry Tree Product (AFTP) are similar to those that will be important for the development of other AFTPs. Thus there are lessons that can be learnt from this species which make it a model for other agroforestry tree species

Ecosystem services from smallholder forestry and agroforestry in the tropics

Smallholder forestry and agroforestry systems in the tropics provide essential products and services for millions of producers, their surrounding communities, national and international consumers, and global society. The diversity of products provided by these systems meet the needs of smallholder producers for fuelwood, food, animal fodder, and other household and farm needs; they provide additional income to supplement major commodity crops; and they offer flexibility in production and income to buffer against falling commodity prices, crop failure, or other sources of financial or economic difficulty. The sustainability of these systems is increasingly dependent upon sources of income beyond the sale of conventional products, such as price premiums from sustainability certification and agro- and ecotourism. Payments for ecosystem services (PES) programs have been developed at multiple levels to provide incentives for smallholders to conserve and enhance tree cover and management practices to provide ecosystem services such as watershed protection and carbon sequestration. Ecotourism provides an enterprise-based strategy to engage producers in conservation and enhancement of these services. This review evaluates the ability of smallholder systems to support the provision of ecosystem services (ES) and the capacity of smallholders to participate in support programs and take advantage of other emerging opportunities to support smallholder enterprises
