The Vetiver Network International (TVNI) makes information on the Vetiver System publicly available to support education, research, farmer adoption, community development, environmental restoration, infrastructure protection, and other public-interest uses.
Unless otherwise stated, the materials on this website are protected by copyright. Some materials are owned or controlled by TVNI; others were prepared by individual authors, researchers, practitioners, conference presenters, institutions, or other third parties. TVNI’s permission policy applies only to materials owned by TVNI or materials for which TVNI has permission to authorize reuse.
Public-interest use encouraged
TVNI encourages the use of TVNI-controlled materials for non-commercial educational, research, nonprofit, farmer-support, community-development, public-sector, humanitarian, and environmental purposes, provided that:
- TVNI and any identified original author or source are properly credited;
- the material is not presented as having been reviewed, approved, certified, or endorsed by TVNI unless TVNI has given written approval;
- any adaptation, translation, or summary makes clear that it is adapted from the original source; and
- the use does not mislead others about TVNI’s role, partnership, approval, or responsibility.
Suggested attribution:

TVNI also welcomes copies of translations, adaptations, and field-use materials prepared from TVNI resources so they can be considered for sharing with the wider network.
Professional and consulting use
Consultants, engineers, NGOs, contractors, trainers, and other professional advisers may cite, link to, summarize, recommend, and apply publicly available TVNI materials when advising clients, communities, public agencies, or project sponsors on the Vetiver System, provided proper attribution is given and no TVNI endorsement, certification, partnership, or approval is implied.
This permission does not authorize copying, adapting, repackaging, translating, compiling, or using substantial portions of TVNI-controlled materials as the primary basis for paid manuals, training courses, credential programs, commercial publications, proprietary methods, commercial databases, software tools, AI systems, or other commercial knowledge products without TVNI’s prior written permission.

Subject line: Permission request — TVNI materials
Requests should identify the material to be used, the proposed use, whether the use is commercial or nonprofit, the intended audience, whether the material will be adapted or translated, and whether the use involves training, certification, software, databases, AI, or paid services.
No implied endorsement or certification
Public availability of TVNI materials does not mean that TVNI has approved a specific project, design, installation, training course, consultant, organization, publication, product, or service.
No person or organization may claim or imply that they are “TVNI-approved,” “TVNI-certified,” “TVNI-authorized,” “TVNI-endorsed,” “TVNI-recognized,” or acting as an official TVNI partner or representative unless TVNI has provided written authorization.
Third-party materials
Many materials made available through TVNI were created by third parties. Reuse of such materials may be subject to the rights of the original author, photographer, publisher, institution, or source. Users are responsible for respecting those rights and for obtaining any additional permission that may be required.
Accuracy and professional responsibility
TVNI provides information as a public resource but does not guarantee that all materials are complete, current, accurate, or suitable for a particular site or purpose. Users are responsible for evaluating the information, applying appropriate professional judgment, and complying with applicable laws, regulations, engineering requirements, environmental standards, and local conditions.
