"Agriculture in the Tropics" is one of the most successful and widely read books in the Tropical Agriculture Series and offers a general account of all the factors that affect agriculture in the tropics. It details the economic and physical factors that affect tropical agriculture and discusses land management and the different types of farming systems in practice. It also discusses tropical crops and the improvements that can be made by effective plant breeding programmes. Information is provided on animal feeds, how animals adapt to their environment and how livestock can be improved by well managed hygiene, breeding and nutrition. The third edition has been fully updated and is an essential reference source for all those requiring a comprehensive introduction to tropical agriculture.

This collection reviews current advances in the breeding and cultivation of key tropical and subtropical fruits. Chapters summarise key advances across the value chain for citrus fruit cultivation, including citrus genetics, nutrition and other aspects of cultivation, the use of precision agriculture and developments in integrated pest management (IPM). Two case studies on limes and mandarins highlight the range of improvements in cultivation. The book also summarises recent developments in breeding and cultivation techniques for a range of soft tropical fruits, including banana, kiwifruit, lychee, papaya, pineapple and pomegranate. The final part of the book covers developments in breeding and cultivation techniques for a range of stone and other tropical fruit, including avocado, coconut, guava, jackfruit, mangos and olives.

Silviculture in tropical forests has a long history going back many centuries and active management for timber production began about two hundred years ago. There is therefore a considerable body of evidence regarding both sustainable and destructive forestry practices in these forests, the future of which is the subject of one of the great scientific and public debates of the late twentieth century. Based on fifty years experience by each author and extensive research of the literature, this book provides information, much of which was previously not widely available, on the development of silvicultural systems in tropical moist forest (a broad term which encompasses many forest types). The book begins by tracing the early history and goes on to describe the later, more technical phases and the growth of global exploitation. Examples from many countries are described in detail, considering all aspects including the economic, ecological and social implications. It is the aim of the authors to demonstrate that sustainable timber production in many of these forests is not only possible, but the techniques necessary have been known to foresters for many decades. This book is essential reading for forest managers in the tropics, advanced students and researchers in forestry and ecology concerned with natural resource management and will also be of interest to economists, policy makers and environmentalists

Soilborne diseases have, until recently, received less attention than plant diseases affecting the shoot and foliage. However, this is not a reflection of their economic importance, but rather of difficulties in investigating and detecting pathogens below soil level. Many soilborne diseases are stress related and it is in the tropics where crop growth is particularly limited by environmental stress, predisposing crops to infection by soilborne pathogens. There is thus a great need for information on soilborne diseases of crops in the tropics. This book aims to fill this need by providing reviews of relevant research. It covers the major tropical crops and also includes general chapters on principles, ecology and control. Written by leading research workers from countries including the UK, USA, Australia and India, it will be indispensable for plant pathologists working in this area.

Agroforestry seeks to balance protection of forest resources, the exploitation of the ecosystem services that trees can contribute to agriculture and the role of agroforestry in diversifying the range of agricultural products and markets. This volume reviews the latest research on the role and implementation of main types of agroforestry, understanding and assessing the ecosystem services that agroforestry can deliver and techniques for optimising agroforestry practice. The book's main focus is on temperate agroforestry, but also reviews particular issues facing agroforestry in the tropics. The collection will be a standard reference for forestry and agricultural scientists in universities, government and other research centres in agroforestry

The literature of Africa is dominated by accounts of crisis and gloom. But Thomas Bassett, a distinguished American geographer well known in the field of development, tells an unusual story of the growth of the cotton economy of West Africa. One of the few long-running success stories in African development, change was brought about by tens of thousands of small-scale peasant farmers. While the introduction of new strains of cotton in French West Africa was in part a result of agronomic research by French scientists, supported by an unusually efficient marketing structure, this is not a case of triumphant top-down 'planification'. Employing the case of Cote d'Ivoire, Professor Bassett shows agricultural intensification to result from the cumulative effect of decades of incremental changes in farming techniques and social organization. A significant contribution to the literature, the book demonstrates the need to consider the local and temporal dimensions of agricultural innovations. It brings into question many key assumptions that have influenced development policies during the twentieth century.

Parasitic weeds of the families Cuscutaceae, Orobanchaceae and Scrophulariaceae are considered to be among the major problems facing agriculture in the Tropics and Subtropics. In the last decades, enormous efforts have been made and success achieved by scientists all over the world in gaining a better understanding of their biology and ecology as well as of control methods. However, no substantial reduction of infestation has been achieved in the past and control strategies specific to the different parasites, crops and farming systems must be further developed or adapted and realised among a wider farming population with suitable extension methods. This `Technical Manual' provides up-to-date methodologies for various aspects of research and extension related to parasitic weed species of the genera Striga, Alectra, Orobanche and Cuscuta. It has the intention to support scientists and extension workers of international and national research and extension institutes and universities, who are either new to the subject or plan to apply further techniques they are not yet familiar with.

This introduction to tropical food science is meant for two groups of people. First, there are those living in the tropics who require a simple introductory text. Food science is perhaps the most important science affecting their lives. The second group consists of students, administrators and workers in industry and research in temperate zones, who are concerned with food problems but who have no first-hand knowledge of the tropics. The text provides a concise and accessible guide to all the major elements of the subject, including the nutritional value of tropical foodstuffs, its digestion, and the preparation and preservation of food. The author has taken care to avoid the use of jargon and the text is supplemented by many useful explanatory illustrations. The volume is suitable for first-year food science students at universities, polytechnics and colleges; graduate students taking conversion courses in food science; administrators, practitioners and students of food science in the tropics.

This book provides an insight into the background, lessons learned, and the methodology of facilitating the application of best-bet/best-fit agricultural technologies to smallholder farms in East and Southern Africa (ESA). All technologies highlighted within this book, except those on livestock feeding, were trialed and demonstrated in farmers' fields over an eight-year period [2012 - 2020] as part of the Feed the Future/USAID funded research-for-development Africa RISING ESA Project and supported by the CGIAR. The livestock feed technologies were compiled from Eastern Africa literature and included to offer a full set of technologies relevant for farmers in mixed farming systems. Topics covered include the introduction of resilient and nutrient-dense crops, better arrangement of crops in the field to amplify intercrop benefits, and the management of soils to improve soil fertility and minimize physical soil and nutrient loss. The publication also features technologies for postharvest loss reduction, livestock feeding, food processing, and in the later chapters, important expositions on how multiple technologies can be creatively integrated in a farming system and how key products of research can be taken to scale. In the first chapter and throughout the handbook, the importance of taking gender dynamics into account to ensure technologies produce equitable outcomes is emphasized. This book: provides evidence-based descriptions of sustainable agricultural intensification technologies that have been validated iteratively with smallholder farmers. a convenient, easy-to-read, and science-based 'how-to' guide for successful deployment of improved agricultural technologies that will ensure readers from development/scaling agencies save time and resources for research trials and instead focus on technology deployment. gives evidence of how building research and development partnerships can be a critical element for successful delivery and scaling up of agricultural technologies. The book is aimed primarily at development practitioners who seek new competences in taking new technologies to scale. However, the breadth of topics covered makes this book an essential resource for agricultural scientists as well as university and college students aspiring to apply systems thinking in future agricultural research and development work.

Tropical mycology is attracting increasing interest, as the key role of fungi in tropical ecosystems and as pathogens becomes appreciated. This book is the second of two complementary volumes (Volume 1 covers Macromycetes) produced from papers given at the British Mycological Society's symposium held in Liverpool in April 2000. It describes the ecology, biology, economic dimensions and systematics of tropical Macromycetes. Written by experts in their field, the papers have been thoroughly edited and revised.

The long-awaited second edition of this classic textbook expands on the first edition to include advances made in the last four decades, bringing the topic completely up to date. The book addresses critical issues such as whether humanity can feed itself, and whether it can do so in environmentally sound and sustainable ways. Written from agronomic, environmental, and ecological standpoints, the textbook employs a multidisciplinary approach, including policymaking and plant genetic improvements, as well as ecosystem services, climate change, biodiversity, sustainability and resilience. New chapters in this second edition focus on organic carbon in soil, soil biology, soils in relation to livestock production and forestry, and agroforestry. The new edition will again be the go-to textbook for courses on tropical soils, and a reference textbook for soil and agricultural scientists and development professionals working in the tropics.

"Banana Systems in the Humid Highlands of Sub-Saharan Africa: Enhancing Resilience and Productivity" addresses issues related to agricultural intensification in the (sub)humid highland areas of Africa, based on research carried out in the Great Lakes Region by the Consortium for Improving Agriculture-based Livelihoods in Central Africa (CIALCA). This book is a valuable resource for researchers, students and policymakers in agricultural economics and international development, covering agronomic, economic, policy, extension, and communication dimensions.

Written in an easily-accessible style, this book provides a practical introduction to all aspects of tropical turf management. General topics covered include climate adaptation, the physiology and morphology of turf-grasses, an overview of the different turf-grass species, soil characteristics and testing, establishment techniques, cultivation, nutrition and fertilization, mowing procedures, irrigation requirements, compaction and thatch, and turf pests. It also discusses golf-course maintenance including the different methods needed for the tee, the fairway, the putting green and the rough. The book also looks at sports field management including rugby fields, tennis courts, football and hockey fields, bowling greens and croquet-courts, and playgrounds. Numerous line drawings and photographs are used to illustrate key concepts, processes and relationships.

Recent research suggests that the application of the old concepts of pasture management developed in Europe, USA and South Africa have been unsuccessful in the Tropics; in some areas under-utilisation has resulted in poor animal output and low economic returns, whereas in other areas overgrazing has resulted in soil erosion and weeds. This book sets out to examine the problems involved in the utilisation of tropical and subtropical pastures and to explain how pastures may be managed to meet the requirements of both plants and animals for growth and replacement. Following an overview of the livestock systems of the tropics, the effects of grazing animals on the edaphic, biotic and climatic environment of the pasture are described. The response of the animals to the available pasture are discussed in terms of pasture attributes of nutritive value and sward structure, selectivity and grazing behaviour. Methods for attaining continuity of forage supply are also described. The author, Professor L. R. Humphreys, has been involved for many years in extensive research of tropical and subtropical pastures. A central objective of his work has been to effect a synchrony between pasture available and the forage requirements of the animal. This book is a culmination of much of his research and will be invaluable to all disciplines with an interest in tropical and subtropical agricultural practices.

Based on the author's widely used earlier text African Farm Management, this account updates the economic analysis of tropical agriculture and broadens its perspective to include examples from all parts of the developing world. Writing in a clear, concise style, Professor Upton explains the essential theories of farm economics without numerous mathematical formulae. The text is completely revised, with increased emphasis on farm household economics, in which farms are seen as consumers as well as producers. Also included is a new chapter on the economics of irrigated agriculture. This book provides an invaluable economic framework for better understanding the operation and management of farming systems in the tropics, and will be welcomed by students of tropical agriculture worldwide. From reviews of African Farm Management: "The author produces an authoritative text interlaced with many relevant and illustrative references." -- Experimental Agriculture

In tropical developing countries farmers tend to grow a wide range of crops in a small area for subsistence or sale. To make full use of often limited resources a good understanding of how environmental conditions affect the characteristics and performance of these crops is essential. This book considers the response of tropical food crops to environmental factors such as climate, soil and farming system. Three types of crop are considered; cereals, legumes and non-cereal energy crops, with individual chapters on the four most important crops in each group. This material is set in context by introductory chapters on tropical farming systems, tropical climates and tropical soils. This updated edition retains the successful formula of the first edition, and will serve the needs of advanced students of tropical agriculture, as well as professionals engaged in research and extension work in tropical crop production.

This is a revised and expanded edition of a popular textbook on the economics of farm households in developing countries. The second edition retains the same building blocks designed to explore household decision-making in a social context. Key topics are efficiency, risk, time allocation, gender, agrarian contracts, farm size and technological change. For these and other topics, household economic behaviour represents the outcome of social interactions within the household, and market interactions outside the household. A new chapter on the environment combines exposition of economic tools not previously covered in the book with examination of household and community decision-making in relation to environmental resources.

This textbook considers the methods used by governments to change the economic and social framework within which agricultural production takes place: by influencing the prices of farm inputs and outputs, by modifying agricultural institutions, and by promoting new technologies in agriculture. The book is organised around a central set of eight policy chapters, covering topics of price policy, marketing policy, input policy, credit policy, mechanisation policy, land reform policy, research policy and irrigation policy. These chapters are preceded by material covering the nature of policy, in the context of the market versus state debate, and the principles used by economists to undertake agricultural policy analysis. They are followed by chapters that examine the status of women in agricultural policy, and that summarise aspects of food policy not covered in the main chapters. This book is designed for undergraduate and graduate students taking courses related to agricultural policy, agricultural economics, or rural development in developing countries. It will also be accessible to the non-specialist reader who wishes to obtain an overview of the individual policy topics covered.

In this book, Leslie Small and Ian Carruthers examine in detail the potentials and limitations of user fees for financing irrigation operation and maintenance. Both authors have extensive field experience in irrigation in developing countries and have combined this experience with simple concepts of economics to examine possible institutional and financial reforms which would not simply ask farmers to pay for an inadequate irrigation service, but would create the potential for significant improvements in the quality of the service provided. The proposed elements of any such reform are discussed in depth - a system of user fees covering the recurrent costs of irrigation; a financially autonomous irrigation agency that can retain and use the fees to operate and maintain the irrigation facilities; and a macro policy environment that is not unduly skewed against the agricultural sector. Written in a style intended to convey economic perspectives and insights to non-economists, this book will be essential reading for all those concerned with the financing and performance of irrigation in developing countries.

The many billions of dollars invested in canal irrigation in recent decades have had disappointing results. Rarely have projected benefits in well-being or production been achieved. In consequence, in the mid-1980s, further vast sums are being spent throughout the Third World on programmes for rehabilitation, canal lining, on farm development, and farmers' organisation. In this book, Robert Chambers shows that much of this policy and practice is based on misleading research and misdiagnosis. When applied to the complexity and uniqueness of canal irrigation systems, the normal professionalism of civil and agricultural engineers, agronomists, economists, and sociologists, leaves gaps which are keys to better performance. In successive chapters, five such gaps are analysed and presented: main system management, including the scheduling and delivery of water, and communications; canal irrigation at night; management of canal systems jointly by farmers and officials; professional conditions and incentives for irrigation managers; and methods for diagnostic analysis to identify cost-effective actions for improvement. Managing Canal Irrigation has been written for policy-makers, irrigation managers, consultants, researchers, trainers and teachers. It challenges all concerned with improving the performance and anti-poverty impact of canal irrigation, whether in government departments, aid agencies, consultancy firms, training and research institutes or universities, to re-examine their beliefs, biases and actions. By going beyond the limits of normal professionalism, the book presents a new syllabus for training, a new agenda for research and development, and points to new policies and to practical action to be taken in the field.
