Looking back to look forward In July 1987, some 50 social and natural scientists of roughly equal numbers met at the Institute of Development Studies (IDS) at the University of Sussex, UK, for a workshop on ‘Farmers and Agricultural Research: Complementary Methods', later more generally known as the „Farmer First' workshop (Chambers et al, 1989). That event marked a key moment in the developmen...

Third, the wood itself has an unusual combination of desirable properties. Its strength is outstanding. It is a prime material for structural plywood. Its light color and the strength of its fibers adapt it for pulping by both chemical and mechanical processes. The self-pruning attribute of the major species permits clear lumber for millwork to be produced in quantity. Further, the form of the ...

In other areas, perhaps reflecting my own more superficial knowledge, I found less to argue with. But I do think in a book aiming to highlight topics which will feature in the MRCP examination, more than a brief paragraph on AIDS would be useful. Having made these criticisms there is much to enjoy in the slightly idiosyncratic approach in this book. It will remain popular amongst MRCP candidate...

Approximently 10,000 years ago, civilization began in the Fertile Crescent of Mesopotamia around the river valleys of the Euphrates and the Tiger rivers. It was agriculture that allowed these civilizations to prosper and the river water that allowed agriculture. The number of people in the world has grown signi cantly since then increasing the demand for food production. Agriculture has been fo...

The belief-desire-intention (BDI) model has been widely used to construct reasoning systems for complex tasks in dynamic environments. We have designed a capabilities and abilities (CA)-BDI farmer decision-making model, which is an extension of the BDI architecture and includes internal representations for farmer household Capabilities and Abilities. This model is used to explore farmer learnin...
