Book Description
Annotation. Successful agroforestry requires an understanding of the complex relationship between trees, crops and soils. This book provides a review of both economic and biophysical aspects of soil use and research in agroforestry, with an emphasis on nutrient-poor forest and savanna soils. Key topics covered include the economics of soil fertility management, cycling of water, nutrients and organic matter, soil structure, and soil biological processes. The book combines synthetic overviews of research results and a review of methods used in research.From the foreword: 2The book is written within a particular context - soil fertility development under agroforestry. At first this may seem very specific and thus limited in appeal and application. But over the last decade or so agroforestry research has been one of the most influential in developing new insights into soil biology and fertility and thus provides a very suitable framework for review of progress. Furthermore the influence of trees on soil is profound and of significance beyond agroforestry systems, so the book is likely to be of interest in the wider spheres of agriculture, forestry and ecological sciences.3 Mike Swift, TSBF, Nairobi, Kenya.

Book Description
Tree species are indispensable to support human life. Due to their long life cycle and environmental sensitivity, breeding trees to suit day-to-day human needs is a formidable challenge. Whether they are edible or industrial crops, improving yield under optimal, sub-optimal and marginal areas calls for uni?ed efforts from the s- entistsaroundtheworld. Whiletheuniquenessofcoconutaskalpavriksha(Sanskr- meaning tree-of-life) marks its presence in every continent from Far East to South America, tree crops like cocoa, oil palm, rubber, apple, peach, grapes and walnut prove their environmental sensitivity towards tropical, sub-tropical and temperate climates. Desert climate is quintessential for date palm. Thus, from soft drinks to breweries to beverages to oil to tyres, the value addition offers a spectrum of pr- ucts to human kind, enriched with nutritional, environmental, ?nancial, social and trade related attributes. Taxonomically, tree crops do not con?ne to a few families, but spread across a section of genera, an attribute so unique that contributes immensely to genetic biodiversity even while cultivated at the commercial scale. Many of these species in?uence other ?ora to nurture in their vicinity, thus ensuring their integrity in p- serving the genetic biodiversity.

Book Description
The global biodiversity and climate emergencies demand transformative changes to human activities. For example, food production relies on synthetic, industrial and non-sustainable products for managing pests, weeds and diseases of crops. Sustainable farming requires approaches to managing these agricultural constraints that are more environmentally benign and work with rather than against nature. Increasing pressure on synthetic products has reinvigorated efforts to identify alternative pest management options, including plant-based solutions that are environmentally benign and can be tailored to different farmers’ needs, from commercial to small holder and subsistence farming. Botanical insecticides and pesticidal plants can offer a novel, effective and more sustainable alternative to synthetic products for controlling pests, diseases and weeds. This Special Issue reviews and reports the latest developments in plant-based pesticides from identification of bioactive plant chemicals, mechanisms of activity and validation of their use in horticulture and disease vector control. Other work reports applications in rice weeds, combination biopesticides and how chemistry varies spatially and influences the effectiveness of botanicals in different locations. Three reviews assess wider questions around the potential of plant-based pest management to address the global challenges of new, invasive and established crop pests and as-yet underexploited pesticidal plants.

Book Description
Bamboo occupies an unparalleled position in the plant kingdom in terms of its distribution, diversity and uses in the tropics and subtropics. In addition to featuring prominently in the lives of rural communities, particularly in Asia, it continues to find new applications in such wide ranging areas as paper and rayon manufacture; construction; architecture; engineering; handicrafts; food and medicine. Within Asia, India is second only to China in terms of the quantities and varieties of bamboo species found in the country. However, as in many other countries, information on this subject is generally inadequate and inaccessible. Contradictory reports on various aspects of bamboos, especially relating to taxonomic and phytogeographic observations, further add to the confusion regarding classification. There is thus an urgent need for a review of the current literature and a compilation of information on the various species of bamboo, including their synonyms. This compilation by K.K. Seethalakshmi and M.S. Muktesh Kumar, scientists specializing in plant physiology and taxonomy respectively at the Kerala Forest Research Institute, seeks to fulfil this need. Based primarily on a literature survey, it provides a comprehensive and holistic account of 128 bamboo species belonging to 18 genera occurring in India. By synthesizing and consolidating the work done so far on each of the covered species, it is expected to illuminate current information gaps and to provide a solid foundation for further work in this area.

Book Description
Forestry professors used to remind students that, whereas physicians bury their mistakes, foresters die before theirs are noticed. But good institutions live longer than the scientists who contribute to building them, and the half-century of work of the USDA Forest Service's Institute of Tropical Forestry (ITF) is in plain view: an unprecedented corpus of accomplishments that would instill pride in any organization. There is scarcely anyone interested in current issues of tropical forestry who would not benefit from a refresher course in ITF's findings: its early collaboration with farmers to establish plantations, its successes in what we now call social forestry, its continuous improvement of nursery practices, its screening trials of native species, its development of wood-processing technologies appropriate for developing countries, its thorough analysis of tropical forest function, and its holistic approach toward conservation of endangered species. Fortunately, ITF has a long history of information exchange through teaching; like many others, I got my own start in tropical forest ecology fromjust such a course in Puerto Rico. And long before politicians recognized the global importance of tropical forestry, the ITF staff served actively as ambassadors of the discipline, visiting tropical coun tries everywhere to learn and, when invited to do so, to help solve local problems. It is a general principle of biogeography that species' turnover rates on islands are higher than those on continents. Inevitably, the same is true of scientists assigned to work on islands.
