This publications covers the outcomes of a research project funded by ACIAR aimed at developing the tree crops sub-sector in Papua New Guinea. Because of its importance in the traded goods sector, the tree crops sub-sector is crucial for economic development in general, and smallholder agriculture in particular. The Department of Agriculture and Livestock (DAL) considers its revitalisation a planning priority. The major component of these reforms is a structural adjustment program that is beginning to have widespread impacts across the economy, including the rural sector. The major challenge facing the tree crops sub-sector in contributing to the success of the program is to develop mechanisms to maintain comparative advantage and international competitiveness.
