The performance of irrigation schemes that carry sediment laden water is often poor. Modern irrigation schemes are increasingly demand based, which means that the water flow in the canals is determined by the crop water requirements. Accordingly the flow in the canal network is not constant as the crop water requirement changes with the climate and the growing stages. Also the inflow of the sediment is not constant throughout the irrigation season. Such schemes, particularly having unlined canals in alluvial soils, are difficult to design and to manage without compromising the flexibility or maintenance cost. This research has made an in-depth assessment on the role of sediment in the design and management of an irrigation scheme by using the data of Sunsari Morang Irrigation Scheme, Nepal. An analysis of the velocity and shear stress distribution across a non-wide trapezoidal canal has been made to derive the correction factor for the sediment transport predictors.

First published in 1988, this work provides a comprehensive picture of the range of physical environments in Africa, focusing upon those characteristics and issues central to the management of environmental resources. Beginning with an overview of the geographical and environmental history of Africa, the authors also provide to the evolution of the management of resources and then details a broadly defined ecosystem approach, in which major environmental resource issues are identified and addressed in the tropical rainforest, the Savannah dry-forest, the arid and semi-arid areas, the highlands, and the extra-tropical zones of Northern and Southern Africa. The book is designed to contribute to a better understanding of African environmental and resource-management problems and this reissue should be welcomed by students of Africa and of environmental resource management problems in general.

Food and Poverty - The Political Economy of Confrontation (Hardcover): Radha Sinha Food and Poverty - The Political Economy of Confrontation (Hardcover)
Radha Sinha
R1,288 Discovery Miles 12 880 Ships in 12 - 19 working days

First published in 1976, this book deals with contemporary tensions between the West and the Third World, caused by hunger, malnutrition and poverty, perpetuated by an imbalance in the distribution of world resources. The book deals with the issue of malnutrition in the Third World, which owes much more to poverty and unemployment than to agricultural failure. The author also believes that population control can do little in the absence of a more equitable distribution of world resources and political power within and between countries involving a fundamental change in ideology and education. This is a challenging and critical book, whose arguments cannot be ignored by anyone concerned with the creation of a just and stable world order.

Broadening the Genetic Base of Grain Legumes (Hardcover, 2014 ed.): Mohar Singh, Ishwari Singh Bisht, Manoranjan Dutta Broadening the Genetic Base of Grain Legumes (Hardcover, 2014 ed.)
Mohar Singh, Ishwari Singh Bisht, Manoranjan Dutta
R5,128 Discovery Miles 51 280 Ships in 12 - 19 working days

Grain legumes play significant and diverse role in the farming systems and provide nutrition security to the largely vegetarian and relatively poorer people around the world. These are ideal crops for achieving three simultaneous developmental goals viz. reducing poverty, improving human health and nutrition and enhancing ecosystem resilience. Globally, grain legumes are the second most important crop group next only to cereals but a large proportion of area of it is under rainfed-low input systems as compared to cereals contributing to lower yields. The other important factor responsible for reduced yield in grain legumes is the narrow genetic base of the present day pulse varieties. In order to break the yield barriers of these cultivars, new sources of genes/ alleles need to be identified and suitably incorporated into the adapted background. The information on various aspects of grain legume improvement although has been considerable in the recent past, these information are highly scattered and not available at one place. The present book consists of comprehensive and latest crop-wise information on important grain legumes of the world including their distribution, gene pool, systematics, status of genetic and genomic resources, production constraints, traits of importance, crop improvement methodologies - both conventional as well as contemporary and future strategies to be adopted for comprehensive grain legume improvement in various agro-ecological target areas of the globe. The chapters have been contributed by eminent crop experts from across the world engaged in research in their respective crops for the past several years thus providing a rare insight into the crop specific constraints and prospects drawing from their rich overall experience. The book therefore will be a useful source of information to the grain legume researchers, students, policy planners and developmental experts alike.

Plant Tissue Culture: An Introductory Text (Hardcover, 2013 ed.): Sant Saran Bhojwani, Prem Kumar Dantu Plant Tissue Culture: An Introductory Text (Hardcover, 2013 ed.)

R8,441 Discovery Miles 84 410 Ships in 12 - 19 working days

Plant tissue culture (PTC) is basic to all plant biotechnologies and is an exciting area of basic and applied sciences with considerable scope for further research. PTC is also the best approach to demonstrate the totipotency of plant cells, and to exploit it for numerous practical applications. It offers technologies for crop improvement (Haploid and Triploid production, In Vitro Fertilization, Hybrid Embryo Rescue, Variant Selection), clonal propagation (Micropropagation), virus elimination (Shoot Tip Culture), germplasm conservation, production of industrial phytochemicals, and regeneration of plants from genetically manipulated cells by recombinant DNA technology (Genetic Engineering) or cell fusion (Somatic Hybridization and Cybridization). Considerable work is being done to understand the physiology and genetics of in vitro embryogenesis and organogenesis using model systems, especially Arabidopsis and carrot, which is likely to enhance the efficiency of in vitro regeneration protocols. All these aspects are covered extensively in the present book. Since the first book on Plant Tissue Culture by Prof. P.R. White in 1943, several volumes describing different aspects of PTC have been published. Most of these are compilation of invited articles by different experts or proceedings of conferences. More recently, a number of books describing the Methods and Protocols for one or more techniques of PTC have been published which should serve as useful laboratory manuals. The impetus for writing this book was to make available a complete and up-to-date text covering all basic and applied aspects of PTC for the students and early-career researchers of plant sciences and plant / agricultural biotechnology. The book comprises of nineteen chapters profusely illustrated with self-explanatory illustrations. Most of the chapters include well-tested protocols and relevant media compositions that should be helpful in conducting laboratory experiments. For those interested in further details, Suggested Further Reading is given at the end of each chapter, and a Subject and Plant Index is provided at the end of the book.

Rajeev K Varshney, Mahendar Thudi, Fred Muehlbauer
R3,063 Discovery Miles 30 630 Ships in 10 - 15 working days

This book sheds new light on the chickpea genome sequencing and resequencing of chickpea germplasm lines and provides insights into classical genetics, cytogenetics, and trait mapping. It also offers an overview of the latest advances in genome sequencing and analysis. The growing human population, rapid climate changes and limited amounts of arable land are creating substantial challenges in connection with the availability and affordability of nutritious food for smallholder farmers in developing countries. In this context, climate smart crops are essential to alleviating the hunger of the millions of poor and undernourished people living in developing countries. In addition to cereals, grain legumes are an integral part of the human diet and provide sustainable income for smallholder farmers in the arid and semi-arid regions of the world. Among grain legumes, the chickpea (Cicer arietinum) is the second most important in terms of production and productivity. Besides being a rich source of proteins, it can fix atmospheric nitrogen through symbiosis with rhizobia and increase the input of combined nitrogen. Several abiotic stresses like drought, heat, salinity, together with biotic stresses like Fusarium wilt, Ascochyta blight, and Botrytis grey mould have led to production losses, as the chickpeas is typically grown in the harsh climates of our planet's semi-arid regions.

Learning From China? - Development and Environment in Third World Countries (Hardcover): Bernhard Glaeser Learning From China? - Development and Environment in Third World Countries (Hardcover)
Bernhard Glaeser
R4,272 Discovery Miles 42 720 Ships in 12 - 19 working days

First published in 1987, this volume was written to shed some light upon the nature and environmental consequences and wider relevance of development strategies in the Peoples? Republic of China. It covers industrialisation, food production, energy use and landscape and settlement planning.

The Chinese "autocentred" strategy is assessed from both the developmental and the environmental viewpoints. Decision-making processes and the opportunities to implement environmental policy in other parts of the developing world are analysed and the volume concludes with the view that benefits to other countries are likely to arise out of increased co-operation and exchange with China, although the Chinese model is by no means a panacea.

All students and researchers interested in either environmental or developmental issues will find this book to be a substantial and enlightening contribution to literature.

The Foxtail Millet Genome (Hardcover, 1st ed. 2017): Manoj Prasad The Foxtail Millet Genome (Hardcover, 1st ed. 2017)
Manoj Prasad
R5,001 Discovery Miles 50 010 Ships in 12 - 19 working days

This book presents up-to-date information on foxtail millet genomics, with a particular focus on its agronomic importance, genome architecture, marker development, evolutionary and diversity studies, comparative genomics and stress biology. The topics discussed have the potential to open up a new era of crop improvement in foxtail millet and other related grass species. Foxtail millet (Setaria italica L.) is the oldest domesticated crop in the world (domesticated >8700 years ago) and it has been extensively grown in the semi-arid regions of Asia, Europe and the Americas as a food and fodder crop ever since. Further, as a C4 crop with close genetic relatedness to several biofuel grasses, foxtail millet has been promoted as a model plant. In view of its importance, the US Department of Energy Joint Genome Institute and Beijing Genomics Institute have independently sequenced the genome of foxtail millet. The availability of the draft genome sequence has advanced the genomics and genetics of this important crop, resulting in the development of large-scale genome-wide molecular markers and demonstration of their utility in genomics-assisted breeding, as well as the identification of the molecular and biological roles of several stress-responsive gene families in connection with abiotic stress tolerance. In addition, several open access databases have been developed to make these resources for crop improvement through structural and functional genomics widely available.

The changing climate, the warming of the world and acid rain are among the greatest problems facing us at the end of the twentieth century. This book describes, for the first time, the effects of these phenomena on the high mountains and the forests of Europe. Mountains and the frozen regions (the cryosphere) not only play a major part in our climatic system, but are also central to our water supplies. Yet our glaciers are shrinking, our lakes and soils are becoming acidified, our forests are damaged and the whole fragile ecosystem of ranges like the Alps and the Caucasus is threatened. Nilsson and Pitt present the evidence and assess the probable effects of these changes on mountain society, tourism, water, flora and fauna. They also examine the uncertainties. Above all they look, too, at the best possible strategies in response to What is happening and at what the next steps should be. Originally published in 1991

The destruction of the tropical forest is one of the major problems of our time. Vast areas are rapidly becoming wastelands which support only a few tough weeds, perhaps some cattle, and the farms allowed to the poor. This book provides a vision of hope: in Latin America. Africa. And South East Asia, growing numbers of people are developing techniques specifically designed to promote the wise use and preservation of remaining forest lands. However, these grassroots strategies are often ignored in favour of grandiose schemes which inevitably fail. This pattern must be broken now or the tropical forests will be lost forever.

The economic value of forest. has long been recognized, but the ways in which that value is calculated and the management policies adopted in consequence have all too often resulted in overuse and irreversible destruction. This is spectacularly obvious around the Mediterranean basin, but it is also true in northern Europe. These five case studies, commissioned by the OECD, examine failures of forest management in Britain, Spain, Italy, Germany and Sweden. They look at both market and intervention policies and show how each can further the destruction of the forests, and they set out ways in which future policies can evade the mistakes of the past.

Tomatoes could not be grown commercially without the help of their wild relatives. A single wild species of rice has helped double rice production in Asia. Wild silk-worms are enabling India to expand its silk industry. A wild carp with resistance to cold has been used to extend Soviet carp production further into the north. Wild genetic resources - the heritable characteristics of wild plants and animals - are used increasingly to improve domesticated crops and livestock and as new sources of food and of raw materials. But habitat destruction, over-exploitation and competition from introduced species is destroying many gene pools even before they have been identified. Genes from the Wild describes the growing contribution of wild genetic resources to the production of food and raw materials, describes their characteristics, explains the benefits and problems of using them and outlines the ways in which they are threatened and the measures being taken to conserve them.

The need to produce food without the destructive chemical horrors of much modern farming, for an intelligent use of dwindling natural resources and for humane forms of production is universal, the practice is limited. This book is an account of one, large, instance of success in practice. Twenty-five years ago, Winin Pereira, a nuclear physicist abandoned academia to start a co-operative farm at Alonde in a tribal area north of Bombay. The group experienced, and finally discarded, all the false hopes and promises of Western originated forms of development: ploughs that ploughed too deep, irrigation systems that lowered water tables, fertilizers and pesticides which managed the earth and became so expensive that poorer farmers were dispossessed. Instead they learnt from the adivasai, or tribal people, who have nurtured or been nurtured by foresets for millennia, ways of applying popular knowledge to contemporary problems. This book is a combination of Pereira's record of achievement of sustainable livelihoods and an account of the farm and its effect on the India around it by a leading British journalist.

R4,642 Discovery Miles 46 420 Ships in 10 - 15 working days

Plant virus and sub-viral pathogens pose severe constraints to the production of wide range of economically important crops worldwide. The crops raised both through true seed and vegetative propagated materials are affected with number of virus and virus-like diseases. The virus may enter into plants through seed planting materials or by vectors. Once the virus is in the field, it multiplies and spreads following definite patterns depending upon the nature of the vector and agro-meteorological conditions. Disease free crops and plants are great economic and social importance in feeding the world's population. Detection of virus and sub-viral agents at initial stages of infection is critical to reduce economic losses. For nearly two decades, ELISA and its variants played a major role in large scale virus testing and also in the production of virus-free planting materials.

While working in the laboratory of Professor Dr. Jacob Reinert at the Freie Universitat Berlin (1974-1976), I had the opportunity to become deeply involved in studying the intricacies of the fascinating phenomenon of somatic embryogenesis in plant cells and protoplasts. In numerous stimu lating discussions with Professor Reinert on this subject, I was fully convinced that somatic embryogenesis would become one of the most important areas of study, not only regarding basic and fundamental aspects, but also for its application in crop improvement. During the last decade, we have witnessed tremendous interest and achievements in the use of somatic embryos for the production of synthetic seeds, for micro propagation, genetic transformation, cryopreservation, and conservation of germplasm. The en masse production of somatic embryos in the bioreactors has facilitated some of these studies. Somatic embryos have now been induced in more than 300 plant species belonging to a wide range offamilies. It was therefore felt that a compilation ofliterature/state of the art on this subject was necessary. Thus, two volumes on Somatic Embryo genesis and Synthetic Seed have been compiled, which contain 65 chapters contributed by International experts. Somatic Embryogenesis and Synthetic Seed I comprises 31 chapters, arranged in 3 sections: Section I Commitment of the cell to somatic embryogenesis; early events; anatomy; molecular basis; gene expression; role of polyamines; machine vision analysis of somatic embryos. Section II Applications of somatic embryos; technology of synthetic seed; fluid drilling; micropropagation; genetic transfor mation through somatic embryos; cryopreservation.

Vijay Paul Sharma
R3,595 Discovery Miles 35 950 Ships in 12 - 19 working days

This book analyses the performance and potential of India's oilseed sector, identifies the major constraints facing the industry and suggests options for increasing the country's oilseed production and productivity, taking into account the changing policy environment, increasing demand, slow growth in domestic production and rising imports. India as the world's largest producer of oilseeds, accounts for about 7-8 per cent of global vegetable oil production. However, the growth in domestic production has not kept pace with the growth in demand. Low yields and high production and market risks due to lack of irrigation facilities and effective risk management have been responsible for widening the demand-supply gap over the years, and the country now imports more than half of its oilseed for domestic consumption. The Technology Mission on Oilseeds (TMO), launched in the mid-1980s, helped achieve self-sufficiency in edible oil production through the spread of technology and the provision of market support. However, increasing demand for edible oils necessitated imports in large quantities, leading to a substantial drain on foreign exchange. Given the competing demands on agricultural land from various crops and enterprises, the production of oilseeds can be increased only if productivity is improved significantly and farmers receive remunerative prices and have assured market access. However, farmers face various constraints in oilseed production; several biotic, abiotic, technological, institutional and socio-economic constraints inhibit exploitation of the full yield potential of crops, which need to be addressed. The book explores these issues using data collected from about 2,000 oilseed growers: 490 soybean farmers, 316 rapeseed-mustard growers, 470 groundnut farmers, 250 sesamum farmers and 470 sunflower growers from selected Indian states. It would be of immense use for scholars and policy makers alike who are working in this field.
