"After some highlights about the emergence of Agricultural Extension in industrialised countries, a detailed outline of its history in Malawi is given. Besides publications the source of assessment of the Malawi extension system are interviews with farmers as well with actual and with retired extension staff from 2001. Recent developments since 2001 are again followed by literature review. As a result there is a clear picture, that despite regular reforms and changes in the extension approach, most of it did not really reach the ground, did not much affect, what happened at field level. The problems could never be solved in a satisfactory way, and as a consequence extension failed to fulfil its role for rural and small farmer development. The most crucial deficit seems to be, that at no times there was enough appropriate extension content, to justify all the efforts and costs of transfer. The recommended technologies were either too risky, or dependent on non-available inputs, too general and not adapted to local conditions. The recent reform, explained in detail in this book, seems appropriate, but also highly ambitious, certainly needing longer periods for full implementation. Looking to the past, one would be rather pessimistic about its chances for success. But seeing new market opportunities emerging and clear indicators for economic growth in Africa and even in Malawi, there is some good reason for hope. The book is a key to better understanding of the past and present problems of agricultural extension systems in Africa."--Publisher's description.

The literature is still one of our biggest frustrations to-day. There is, in one sense, too much of it, and in another not enough - for there are insufficient and inadequate published guidelines through this jungle. Last year two excellent books for students of ecological chemistry were published, one in France and one in England. The concordance of the references was a mere overall 3% rising to 7% in the chapters on pheromones. Even in the computer age, the channel remains a formidable barrier to the rapid exchange of biological information. At the present time we are in urgent need of compilations similar to John Feltwell's "The Large White Butterfly"; since the literature has become virtually unmanageable. This insect is now a demonstration object in the sixth form schoolroom; an experimental "rabbit" in the University laboratory; a test animal in virus and bacterial research projects; a tool for the study of flight mechanisms, migration, plant biochemistry, hormones, genetics, allergies, pigments, mimicry, etc. , etc. John Feltwell has, by this massive compilation, rendered us a great service - in fact he has given us a present of 4,000 hours of library time spent in 50 different libraries in seven countries. In the process he has collected 8000 references to the Large White. Of these, 4000 have been selected, and we are given a brief indication of their contents.

Why birds are smarter than we think Birds have not been known for their high IQs, which is why a person of questionable intelligence is sometimes called a "birdbrain." Yet in the past two decades, the study of avian intelligence has witnessed dramatic advances. From a time when birds were seen as simple instinct machines responding only to stimuli in their external worlds, we now know that some birds have complex internal worlds as well. This beautifully illustrated book provides an engaging exploration of the avian mind, revealing how science is exploding one of the most widespread myths about our feathered friends—and changing the way we think about intelligence in other animals as well. Bird Brain looks at the structures and functions of the avian brain, and describes the extraordinary behaviors that different types of avian intelligence give rise to. It offers insights into crows, jays, magpies, and other corvids—the “masterminds” of the avian world—as well as parrots and some less-studied species from around the world. This lively and accessible book shows how birds have sophisticated brains with abilities previously thought to be uniquely human, such as mental time travel, self-recognition, empathy, problem solving, imagination, and insight. Written by a leading expert and featuring a foreword by Frans de Waal, renowned for his work on animal intelligence, Bird Brain shines critical new light on the mental lives of birds.
