An empirical analysis of sugarcane production in Fiji, 1970-2000

Fiji is a small island country in the South Pacific. Sugar is its oldest industry, being in the vanguard of economic growth and development for over a century. Today the oldest industry, not only in Fiji but also in the South Pacific Island countries, is shrivelling and is poised on the precipice of collapse. The literature to date has singled out expiring land leases and the inability of the government to resolve this issue as the key to the current calamity. This paper aims to estimate a sugarcane production model for Fiji, delineating the short-run and long-run determinants. It expands the Cobb-Douglas production function in specifying the sugarcane production model and uses time series data (1970-2000) in estimating it. The major findings are that area harvested and fertiliser (capital), labour force and prices paid to sugarcane farmers have made positive contributions to sugarcane production in both the short- and long-run. The finding on the statistical significance of area harvested has direct relevance to the current land problems in Fiji. It is envisaged that the results will appeal to Fijian policy makers and that a speedy solution to the problem of expiring and non-productive use of sugarcane land will be achieved.

The relationship between Fiji Sugar Corporation's profitability and sugarcane production: an empirical assessment

The Fiji Government's inability to resolve the differences over land leases is widely seen as a major contributor to the difficulties experienced by the sugar industry. In this paper, however, a different perspective is provided on the industry's problems. In examining the relationship between the profitability of the Fiji Sugar Corporation and sugarcane production, it is found that profitability has had a statistically significant negative effect on sugarcane production, leading to the conclusion that the Fiji Sugar Corporation has been inefficient in the management of the mills, the rail transport system, and sugarcane research.

Homogeneous isolation of nanocelluloses by controlling the shearing force and pressure in microenvironment

Nanocelluloses were prepared from sugarcane bagasse celluloses by dynamic high pressure microfluidization (DHPM), aiming at achieving a homogeneous isolation through the controlling of shearing force and pressure within a microenvironment. In the DHPM process, the homogeneous cellulose solution passed through chambers at a higher pressure in fewer cycles, compared with the high pressure homogenization (HPH) process. X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) demonstrated that entangled network structures of celluloses were well dispersed in the microenvironment, which provided proper shearing forces and pressure to fracture the hydrogen bonds. Gel permeation chromatography (GPC), CP/MAS 13C NMR and Fourier transform infrared spectroscopy (FT-IR) measurements suggested that intra-molecular hydrogen bonds were maintained. These nanocelluloses of smaller particle size, good dispersion and lower thermal stability will have great potential to be applied in electronics devices, electrochemistry, medicine, and package and printing industry. © 2014 Elsevier Ltd.
