Slash-and-burn agriculture continues to expand in many parts of the forest zone of Cameroon. One alternative land use to slash-and-burn system is alley farming. This paper quantifies, using an econometric model, the factors determining farmers’ adoption and use of alley farming variants in southw...

Low use of chemical inputs has been cited as a major factor limiting productivity growth of agriculture in most of sub-Saharan Africa. A wide range of variables influence adoption of such input. It is important to understand the role of these factors to ensure the development and implementation o...

Since the 1950s, export credits have been an important source of finance in most African countries, where they allow more to be invested with less sacrifice of current consumption. This paper provides a framework for comprehensively measuring indebtedness and gives, therefore, a basis for setting...

This paper analyses food consumption in rural households of forest zones. Based on a panel survey of 80 households in Cameroon, expenditure-elasticities of demand for roots and tubers are estimated and compared with those of other staples. Yam and cassava are the two most important root and tuber...

This study utilizes frontier metaproduction functions to analyze inter‐region agricultural productivity differences. Technical efficiency scores are examined through estimation of stochastic frontiers for 16 African countries divided into three different regions (West Africa, East and Southern Af...
