Solving Third World Food Problems: The Role of Post-Harvest Planning

  • Martin Greeley
Part of the Nato Advanced Study Institutes Series book series (NSSA, volume 46)


There is a substantial body of literature which argues that developing countries’ food shortages can be reduced, even removed, by preventing post-harvest food losses. It has spawned major research and development and extension initiatives, often funded through aid, that seek to improve farm-level post-harvest systems. Attention has focused on the major cereal staples which are the subject of this paper. Section I examines why the role of post-harvest planning has been characterized in this way. Section II challenges the conventional assertion of high farm-level food losses using evidence from recent field studies. Section III provides a reassessment of the opportunities for and consequences of farm-level post-harvest technical change.

    These are figures originally published internationally in “Rice Post-Harvest Problems in Southeast Asia,” International Food Technologists Meeting, Philadelphia, June 1977, and elsewhere they are cited as IRRI and FAO figures. They give total maximum losses of 31.43%, but several papers, e.g. H.A. Parpia, More than Food Would be Saved, Ceres, December 1977 report 37% losses because they fail to take account of reductions in the quantity available due to loss at earlier stages.Google Scholar

Thesis, Dept. of Entomology, Agricultural College, Bapatla, 1973 (unpub.); S. Srinivasan, Studies on Degree of Infestation by Rice Weevil Sitophilus Oryzae L. in Different Varieties of Paddy and Rice, MSc Thesis, Dept. of Entomology Agricultural College, Bapatla, 1972 (unpub). Both demonstrate the need for plant breeders to take account of resistance to store insect pests by showing how some modern thin-husked rice varieties are more susceptible to the rice weevil (Sitophilus Oryzae L.) and the lesser grain borer (Rhizopertha Dominica (Fab.)). This is supported by field observations of the effects of this factor on the timing of sales of, e.g. RP4–14, by paddy cultivators in West Godavari, A.P.

    India has been very active both in research with the Indian Grain Storage Institute and the All India Co-ordinated Post-Harvest Technology Scheme and in extension with the Save Grain Campaign. In Africa, Zambia, Kenya and Swaziland all developed extension programmes quite early on and in Nigeria the West African Stored Products Research Unit has made important contributions to research from an early date.Google Scholar
