    This Statement outlines agreed objectives and policies for the future of Australia's public and private forests. The Governments share a vision of ecologically sustainable management of Australia's forests. This vision has a number of important characteristics: 1) The unique character of the Australian forested landscape and the integrity and biological diversity of its associated environment is retained. 2) The total area of forest is increased. 3) There is a 'holistic' approach to managing forests for all their values and uses so as to optimise benefits to the community.

    This paper is concerned with understanding cattle production in Zimbabwe's Communal Lands, in so-called communal farming systems. Although commercial offtake from Zimbabwe's communal cattle herd is low, communal farmers are productive and rational in their cattle herd management. The economic rationale for cattle ownership is firstly to provide draught power and manure for tillage and secondly to provide milk and meat for local consumption, although the role of livestock in the farming system varies significantly from one part of Zimbabwe to another.

    En el curso de la historia, los bosques fueron apreciados por la multiplicidad de productos y beneficios que rendan, ya sea como medio de subsistencia que de comercio: comestibles, medicinas, especias, resinas, gomas, ltex, fauna, combustible, y madera y productos forestales, etc. La literatura contiene una gran cantidad de ejemplos de comercio internacional de productos forestales, muchos de los cuales se refieren a la ms remota antigedad. Casi siempre se trata de resinas, aceites, especias, etc., y raramente de madera.

    Tout au cours de l'histoire, les forts ont t estimes pour l'abondance des biens qu'elles prodiguent: produits de subsistance et produits d'change, aliments, remdes, pices, rsines, gommes, latex, gibier, bois de feu et, naturellement, bois d'uvre avec tous ses drivs. Les textes foisonnent d'exemples de commerce international de produits forestiers remontant pour beaucoup des milliers d'annes. Il est d'ailleurs intressant de noter que ces changes portaient davantage sur les rsines, les huiles et les pices que sur le bois.

In this issue, Unasylva examines several facets of watershed management.

    Throughout history, the forests have been valued for the multiplicity of products and benefits that they provide, both for subsistence and for trade: foods, medicines, spices, resins, gums, latexes, wildlife, fuelwood, and of course timber and other wood products. The literature is rich with examples of international trade in forest products, many dating back thousands of years. Significantly, in most cases the products sought by traders were resins, oils, spices, and much less frequently timber.
