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.

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.

Extensive grazing is the predominant form of land use on at least a quarter of the world’s land surface, in which livestock are raised on food that comes mainly from rangelands. Extensive grazing differs from crop or forestry production, in which the produce remains in situ whilst growing. Evaluation for extensive grazing, unlike that for cropping or forestry, must take into account the production of both grazing forage, termed primary production, and the livestock that feed on this forage, termed secondary production.
