Soil and land resources research in five S.W. Pacific nations

Abstract

This work represents major contributions for understanding and managing soils in five SW Pacific Islands. The work covers 40 years of research developing soil information systems through mapping, laboratory characterisation (physical, chemical, mineralogy); spatial analysis; developing agro-technology transfer methods; and introduction of a soil classification “language” (US Soil Taxonomy). The information assisted governments to make sound environmental, land use, planning, and land management decisions. It was however the Soil Resource Manuals, assessment of crop suitability ratings for >50 crops, crop suitability maps, and crop gross margins for each crop and country which aided growers. The work expanded the capacity and capability of the agricultural workforce in extension activities, through training, advisory services, and advocacy. Ancillary research followed, i.e. reviews of rural land use and land use policies, to ensure sustainable management of national soil resources. The research culminated in publication of 57 research papers and 22 books and scientific reports.
