Total factor productivity in South African agriculture, 1947‐91

Indices of total factor productivity (TFP) measure aggregate output per unit of aggregate input, providing a guide to the efficiency of agricultural production. This article outlines the relationship between production functions and TFP indices. Then, an index is constructed for South African agriculture for the period 1947‐91. The index shows that TFP grew at an average rate of 1,3 per cent per annum. However, TFP growth has increased since the reforms of the early 1980s. Since capital has been more realistically priced relative to labour, greater productivity growth has gone together with increasing employment, which must have improved social welfare.     

An African fertilizer crisis : Origin and economic effects in the Gambia

In 1985, fertilizer did not arrive in the Gambia in time for the cropping season, since a fertilizer grant was not being properly managed and coordinated. The costs of such policy failure are high. Fertilizer use was down by 64%. In this situation of scarcity, fertilizer use was even more skewed than before towards rich farmers. Output lost was about 10% of agriculture's GDP. Even in normal years in the Gambia, fertilizer use in millet and groundnuts is found far below optimal levels.     

Agriculture: Toward the year 2000

When the World Food Conference of 1974 demanded the eradication of world hunger within the brief time span of ten years, experts and laymen alike were surprised. The target seemed too ambitious, and it can be safely expected that it will not be achieved. A study has now been submitted by FAO to its 20th Plenary Conference session which—without proposing a new target date—attempts to prove the feasibility of greatly reducing world hunger before the advent of the 21st century.
