First published in 1972, Farm Management in Peasant Agriculture remains the only detailed discussion of on-site research techniques for economists working on the development of small-holder agriculture in Africa. Part 1 describes the conditions of the agricultural sector within which the African peasant farmer must operate, and then outlines an approach to farm management tailored to those conditions. Part 2 sets out the research planning and investigation tasks implied by the approach. Survey techniques, as well as the value of a pre-survey for understanding general attributes of a farm system, are reviewed, and alternative data-collection methods are elaborated. Part 3 shows how research data can be used in planning content for extension programs. Dr. Collinson concludes with the details of a planning method that interpolates changes in farm practice into a model of the existing farm system and that projects a sequence of changes, representing a sequence of extension content, on the basis of farmer acceptability.

This Action Plan describes the conservation status of 23 species of the order Crocodylia found worldwide. The plan is arranged in three principal sections: an Introductory overview, Country accounts, and Species accounts. Each Country account describes the status of wild populations, and current management programmes. The Species accounts summarise the conservation status, principle threats, and existing management programmes and then describe the ecology and natural history of the species and set out recommended priority conservation projects.
