ABSTRACT
Agriculture is the most crucial sector in the South Pacific Island Countries and similarly in
Tonga it plays a pivotal role in economic growth and development. In particular, the export of
squash pumpkins from Tonga to Japan is one of the few successful stories of agricultural export
from the South Pacific Island Countries. During 1990s, the squash pumpkin industry uplifted the
Tongan economy from negative growth to a 5.4% growth in 1999 (Asian Development Bank,
2005, as cited in KautokeHolani, 2008). This demonstrates the greater economic importance of
squash pumpkin industry in Tonga. The squash pumpkin industry further contributes to the
Tongan economy via its backward and forward linkages in the supply chain. Against this
backdrop, this paper will examine the economic contributions of the squash pumpkin industry in
Tonga. The paper will also analyse the supply chain of the Tongan squash pumpkin industry.

1. Introduction
The production of squash pumpkin began in 1987. Japan is the largest importer of Tongan
squash pumpkin with approximately 12,000 tons imported each year (Felemi, 2001: 8). On
average, trade statistics indicate that the squash industry alone accounts for 70% of all
agricultural exports, contributes around 50% towards Tonga’s total export earnings, contributes
25% to the GDP and employs approximately 38% of people employed in the agriculture sector
(Tonga Department of Statistics, 2010). In this context this paper will examine five major aims
related to the Tongan squash pumpkin industry. First, it will examine the economic contribution
of squash pumpkin industry to Tonga’s economy. Second, it will highlight the background of
the squash pumpkin industry, the various stakeholders present in the industry and the
institutional setup of the squash industry. Third, it will map the squash pumpkin supply chain
and discuss the various node of the supply chain. Fourth, it will identify the various problems
and constraints of the squash industry. Finally, it will discuss whether there is opportunity for
value adding and the uncertainty of future export in the Tongan squash pumpkin industry.
2. Literature Review
To date, few scholarly articles have been published that have rigorously analysed the Tongan
squash pumpkin industry by using a supply chain analysis. Only a few academic articles have
