Independent Steering Committee

The Independent Steering Committee (ISC) of the CGIAR Research Program on Roots, Tubers and Bananas (RTB) is responsible for the oversight of the implementation of RTB. The committee guides management of the program for strategic results, and recommends proposals, annual work plans, reports and budgets for approval by the Board of the International Potato Center, RTB’s lead center.

The committee currently comprises eight members. Five are independent members with competencies in gender, partnership, evaluation, and theory of change, as well as capacity strengthening and cutting-edge science. Independent members are appointed for three years, with possible reappointment for an additional three years.

The ISC includes the Director General (DG) of the lead center as a permanent member, a DG of another RTB participating center (on a rotating two-year appointment), a high-level scientist from CIRAD who represents French institutions CIRAD, IRD, INRA and Vitropic. Both DGs represent all partner CGIAR centers. The RTB Program Director is an ex-officio member.

The ISC chair and secretary are elected from among the independent members. The group meets in person once a year, with quarterly virtual meetings and the chair’s interim email updates.
