The objective of this paper is to identify some of the salient characteristics of agriculture in the new millennium. The driving force behind economic change is technology and information, and information and knowledge will replace land, labour and capital as the sources of wealth in agriculture. The resultant cognitive-technical complex in farm production will lead to the true industrialisation of farming and thus placing the traditional family farmer at a distinct disadvantage. Technology developments combined with inverse population growth and ageing population, will not only negate Malthusian visions, but also lead to downward pressure on farm commodity prices, and thus increase the adoption rates of new technology. However, in reaction to the increasingly complex nature of modern society a demand is developing for terroir-based products. This range of products may not only significantly change some characteristics of agriculture, but also provide a new set of opportunities for farmers. Agricultural policy and development strategies should also be reconsidered in the light of this new environment.

Linear Alkylbenzenesulphonates (LAS), a major anionic surfactant used in laundry products, can be measured specifically in the environment by instrumental analysis. In addition to a desulphonation-gas chromatography approach, a method based on high performance liquid chromatography has been developed. The main features of the methods are outlined, and LAS concentrations measured in sewage sludge, sediments and sludge amended soils are reported.Knowledge of usage volumes, sewage treatment practices and environmental transport and transformation mechanisms has been used to predict coiicentrations of LAS. These calculated concentrations were found to agree well with those actually measured in the environment.Both measured and calculated ambient concentrations of LAS are below those which could produce potentially adverse effects in representative surface water, benthic and terrestrial organisms.
