Guidelines for research and visits to Mangyan communities

These guidelines were approved by leaders from the seven Mangyan groups in Oriental Mindoro through the Kapulungan Para sa Lupaing Ninuno (KPLN) – the Federation of the Peoples Organizations in Oriental Mindoro – in March 2006.

The KPLN discourages visitors and researchers going to Mangyan communities that do not abide by these and other guidelines of the groups in Oriental Mindoro. (The eighth Mangyan group – Ratagnon – is in Occidental Mindoro.)

The Mangyans uphold their intellectual property rights under the Indigenous Peoples Rights Act (IPRA) of 1997 and existing and generally accepted international conventions on intellectual and genetic property rights of indigenous peoples.

Visiting and conducting research in any Mangyan community requires the explicit consent of the community. Walk-in visits are strongly discouraged.

Note: The Mangyan Heritage Center (MHC) welcomes researchers and visitors to its library/archive, which contains a comprehensive collection of documents on the Mangyans.

Request letter

Researchers and proposed visitors must outline their request in a letter addressed to the president or chairman of the people's organization (PO) of the relevant group (see below). 

The letter should clearly state the:

  • objectives of the research/visit
  • number of participants
  • inclusive dates and length of visit
  • complete address of the sender and contact information, including e-mail address
  • possible benefits the research would bring to the community (for researchers).

The letter could be sent in PDF format (with signature) to the MHC's email address: /   It must be written in Tagalog/Filipino – translation from English to Tagalog can be provided by the MHC if the researcher could not write in Tagalog.

However, there is no guarantee as to how long it takes for the letter request to reach the intended recipient.

Thus, the MHC suggests that researchers contact directly or deliver personally their letter request to the concerned leader.

Follow up

The request must be followed up two weeks after it was sent through e-mail.  This may be done by calling or emailing the MHC.

Receipt of the request will be acknowledged. Follow up on the response of the community will be at least a further two weeks from date of acknowledged receipt of the letter.

If a request is rejected, the reason will be disclosed. This may be due to:

  • security issues
  • research topic unacceptable to the tribe
  • conflict of schedules.


If a request is approved, the following conditions must be observed:

  • Researchers and visitors are expected to be culturally sensitive and undertake an orientation given by the MHC, MM or the KPLN staff in Calapan before going to the community.

  • Taking of photos and videos is subject to the approval of the community leader.

  • The different Mangyan groups have different cultural practices and beliefs. Upon arrival, visitors will be briefed by the leader on the aspects of their culture that can be documented and those that cannot, the sites that can be visited and those that are not open to outsiders and other important information.

  • Researchers are required to give the community an original copy of their study upon completion (whether hard copy, including photos, audio or video).

  • Neither the community nor the Mangyan leaders will be liable for any untoward incidents that may happen during the research/visit.

  • The MHC, KPLN, MM and POs are not liable for any untoward incident that may happen upon your entry into the community. It is reiterated that such incident is beyond our control.

  • Researchers and visitors may undergo post-visit processing facilitated by MM field staff or the KPLN/PO.


If a research study will be published, it must be validated and approved (following IPRA provisions) by the Mangyan group/s it covers prior to publication. If the published material becomes commercially successful, applicable laws for payment of royalties to the relevant Mangyan group/s will apply. Please contact us for further information.
