TREES AS TOOLS,TREES AS TEXT: STRUGGLES OVER RESOURCES IN ZAMBRANA-CHACUEY,DOMINICAN REPUBLIC

The people of the Rural Federation of Zambrana-Chacuey, in the Dominican Republic, are engaged in complex and multivalent struggles over resources in a forest and farm landscape subject to rapid land use change. Acacia mangium, a fast growing tree recently introduced as a timber cash crop, has become an object, a site and a tool of struggle in conflicts between local and state interests, and between women and men. Until recently, tree cutting has been illegal, so the government-approved acacia has reversed the role of trees from liabilities to assets in land tenure. The acacia has also begun to alter the pattern of land use, land cover, and the species composition of the region's forests, gardens, and fields, and could replace women's diverse gardens with single species blocks of timber.     

Planning in the 1990s: An international agenda

This paper, originally presented to the AESOP‐ACSP joint conference in Oxford in 1991, stresses that both in Europe and in the US, there is a major difference for planning in the switch from boom to recession. During the 1990s a major challenge will be to find new ways of public‐private partnership in financing new urban infrastructure at a time when developer contributions — a major innovation of the 1980s — have dried up. This particularly applies to the European high‐speed train system — one critical element of which will run through the East Thames Corridor, one of Britain's major urban developments in the coming years. In the US, planners are likely to remain more locally focused, less internationally concerned, than in a Europe in which national barriers are rapidly eroding.     

X-ray fluorescence analysis of late Roman and Sassanian silver plate

About 200 analyses have been made on late Roman and Sassanian silver objects using energy-dispersive X-ray fluorescence. This has shown that the main feature of the composition of the silver throughout the period and across the geographical area studied was towards high fineness (average silver percentage about 95%). Compositional differences are found between Roman and Sassanian silversmiths' products for the elements copper and lead. Much of the material analysed came from hoards, and using a statistical technique on the analytical data (Discriminant Analysis) broad compositional differences between hoards were found to emerge. The use of different compositions of silver for different joined parts of a single object are discussed.
