Focal point
Location
The Food and Agriculture Organization of the United Nations leads international efforts to defeat hunger. Serving both developed and developing countries, FAO acts as a neutral forum where all nations meet as equals to negotiate agreements and debate policy. FAO is also a source of knowledge and information. We help developing countries and countries in transition modernize and improve agriculture, forestry and fisheries practices and ensure good nutrition for all. Since our founding in 1945, we have focused special attention on developing rural areas, home to 70 percent of the world's poor and hungry people.

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.
Watershed management
To produce the desired results, therefore, watershed management efforts must incorporate "forest hydrology", "soil and water conservation" and "land use planning" into a broader, logical framework that takes into consideration not only physical interrelationships but economic, social and institutional factors as well. In this issue, Unasylva examines several facets of watershed management.
The development of aquaculture and culture based fisheries in Ghana: the social and cultural contexts
Agriculture, forestry and fishing are important sectors of Ghana's economy and improvement in the performance of these sectors is central to the country's current economic recovery programme.1 The severe economic decline which the country went through between the early 1970's and the early 1980's affected poorer socio-economic groups in particular 2 through depressed wage levels and increased unemployment.
Aménagement des bassins versants
Ainsi, pour parvenir aux rsultats souhaits, les activits d'amnagement des bassins versants doivent intgrer l'hydrologie forestire, la conservation des sols et des eaux et la planification de l'utilisation des terres dans un cadre logique plus vaste, qui tienne compte non seulement des interactions concrtes mais aussi des facteurs conomiques, sociaux et institutionnels. Le prsent numro d'Unasylva examine plusieurs aspects de l'amnagement des bassins versants.
Forest products
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.
