Agribusiness on a Grand Scale – Felda's Sahabat Complex in East Malaysia

While agribusiness is normally associated with western multinational companies, Malaysia provides an alternative example of a Third World agribusiness, the Federal Land Development Authority (FELDA). FELDA has evolved through an advisory stage and then a major land settlement agency phase, assisting Malaysia's rural poor, to its present position as a major employer of immigrant agricultural labour and as a large commercial business in palm oil exporting. This recent agribusiness approach is best exemplified by FELDA's Sahabat complex of 54 schemes in Eastern Sabah. There, mono‐cultural oil palm cropping has been successfully developed while earlier environmental concerns have been largely ignored. Plans for Sahabat have been modified to accommodate immigrant labourers from Indonesia and the Philippines rather than local settlers from Malaysia. A modernised plantation approach has taken over from the initial contract farming and social engineering approach.

A GIS-based research on the distribution of rural settlements in Yulin of northern Shaanxi

The development and distribution pattern of rural settlements was greatly limited by their natural and social environment. Taking Yulin prefecture in northern Shaanxi’s Loess Plateau area as an example, 1:250,000 map-scale national geographical database as a major information source, a GIS-based research was conducted to investigate the spatial distribution of the rural settlements. In this paper, many significant characteristics of the rural settlement distribution are reviewed by means of a series of GIS-based information processing methodology. The results obtained in this study should be helpful for the urban and rural settlements reconstruction planning in this area.
