Publication Policy: Agroforestry Systems is an international scientific journal that publishes results of original research critical reviews and short communications on any aspect of agroforestry. Papers dealing with both biophysical and socioeconomic aspects are welcome. These include results of investigations of a fundamental or applied nature research methodologies and techniques and analytical descriptions of little-studied but potentially promising agroforestry and such other integrated systems involving trees and crops and/or livestock. To be acceptable for publication the information presented must be relevant to a context wider than the specific location where the study was undertaken and provide new insight or make a significant contribution to the knowledge base. Frequency of Publication: The journal is published in three volumes per year. Each volume consists of three issues and each issue contains approximately 80 printed pages (1 printed page is approx. 500 words). On average a research article will have 15 pages. Short communications will be much shorter and will consist of incomplete or initial results that have not yet been conclusively proven. Book reviews and other professional information will also be published periodically. A collection of papers dealing with a specific theme (e.g. proceedings of special workshops and symposia or invited papers on a selected topic) may occasionally be published as a special issue of the journal. One or more specifically designated guest editors working in concert with the Editor-in-Chief will handle the editorial processing of each special issue. Presentation and Style: The journal's language is English. 'American' or 'British' English may be used. However the entire text of each paper should follow any one style only. Detailed 'Instructions to Authors' are published at the end of each volume of the journal and are available on request from the Publishers or the Editor-in-Chief. Prospective contributors are advised to follow these instructions as well as consult a recent issue of the journal for style and format. Peer Review and Editorial Process: All manuscripts including short communications and special-issue articles will be peer-reviewed by at least two independent reviewers who may be members of the Editorial Board or outside experts. The Editor-in-Chief is responsible for the overall editorial process and coordination. He is assisted by four Associate Editors who will coordinate the review process of manuscripts dealing with subjects of their respective expertise.
