We're delighted you're considering joining the International Society for Tropical Root Crops. Here’s everything you need to know about our membership options.

Membership Types

Ordinary Membership

Ideal for individuals who are passionate about supporting and promoting the Society’s goals.

Student Membership

Perfect for university or school students—and those studying agriculture—who share our vision.

Sustaining Membership

For institutions and organisations dedicated to furthering our mission.

Life Membership

A one-off fee option for ordinary members or awarded to those recognised for their outstanding contributions.

Subscription Fees

The fees for each membership type are determined by the Council during the Symposium and approved by the General Meeting. Please note that membership will be suspended automatically if Society dues are not paid by or during the triennial Symposium, and will be reinstated only once any outstanding amounts are cleared. Fees are payable for three years in advance.

Membership Privileges

Members who attend the General Meeting have full voting rights and can be elected to the Society's Council. (Sustaining members receive one vote, though they aren’t eligible for election.) Additionally, members enjoy our Newsletter and other communications free of charge—Symposium proceedings are complimentary for registered participants. ISTRC members also receive a special discount.
