LOS DOS SABERES Jeffery W. Bentley and Keith L. Andrews

The book Los Dos Saberes (two bodies of knowledge, or two ways of knowing) compares agronomic science with farmer knowledge in four regions of Guatemala. The two bodies of knowledge do have their differences, but they often have much in common. Agricultural scientists and farmers are, after all, fairly pragmatic people, and empirical (in the best sense of the word). Attempts to polarize formal and folk knowledge are probably misguided.

This is a book to help people recognize and interpret symptoms in trees, a process known as field diagnosis. Richly illustrated with a wide range of unhealthy looking features from 60 tree species used in forestry and agroforestry (including fruit trees) from around the world, this is a practical guide for gaining a better understanding of what has gone wrong – and using the (field) diagnosis to work out what to do next. The book includes photographs of specific symptoms and damage on foliage and branches as well as a more general decline of older trees.

The wave of on-farm research with farmers themselves (the so-called "participatory" research) largely bypassed the coffee sector. Coffee is a perennial crop which can be (or not) environmentally sustainable, and socially equitable, depending on how the crop is grown, which is why it is crucial to involve farmers in research. This manual looks at the successes and failures of coffee research in Mexico, Honduras, Colombia and Ecuador to explain research methods, relating with farmers, extensionists and scientists, learning farmers' research needs, conducting research in communities and research protocols.
