FAO - The Food and Agriculture Organization of the United Nations was founded at Quebec, Canada, in October 1945 when its member nations agreed to work together to secure a lasting peace through freedom from want. The Headquarters office of the Organization was located at Washington D.C., U.S.A., until 1951 when it was moved to Rome, Italy. The membership of FAO now stands at 101 nations with 3 associate members.
Unasylva - Started in 1947 by MARCEL LELOUP, first Director of the Forestry and Forest Products Division (present Director, EGON GLESINGER), this quarterly publication is intended to cover a range of interests which is as wide as that of the Division whose work it mirrors. Signed articles express the opinions of the authors and do not necessarily represent the views of the Organization. All material published in Unasylva may be freely reprinted but acknowledgment is requested, together with a copy of the publication which contains the reprint. Editor: LESLIE J. VERNELL.
COVER PHOTOGRAPH. Expressive of present-day paper needs are these stocks
alongside a floating stream in Finland. The key role given to education in the
developing countries of the world will result in a much larger demand for paper.
Increased consumption of paper will, however, require additional investments
in the printing and publishing industry. With UNESCO and the Swedish Institute
for International Economic Research, FAO is now investigating the problems involved.
