In acknowledging the various forms of support which contributed to the success of this workshop, a special debt of gratitude is owed to the International Development Research Centre (IDRC), Canada, for sponsoring the workshop, and to both ILCA and the University of Ibadan, Nigeria, for joining forces with IITA to organize and hold the workshop. The excellent leadership provided by Professor G.N. Egbunike in the organization of the workshop is particularly appreciated.
In producing this volume of proceedings, editorial processing and graphic design work was carried out by staff of the Publications Unit of IITA, while printing was paid for and executed at ILCA. The technical support of both institutes, IITA and ILCA, is gratefully acknowledged in making available this volume and thereby fulfilling the workshop's larger goals of increasing awareness of the subject.
