During the past 15 years, cellular and molecular approaches have emerged as valuable adjuncts to supplement and complement conventional breeding methods for a wide variety of crop plants. Biotechnology increasingly plays a role in the creation, conservation, characterization and utilization of genetic variability for germplasm enhancement. For instance, anther/microspore culture, somaclonal variation, embryo culture and somatic hybridization are being exploited for obtaining incremental improvement in the existing cultivars. In addition, genes that confer insect- and disease-resistance, abiotic stress tolerance, herbicide tolerance and quality traits have been isolated and re-introduced into otherwise sensitive or susceptible species by a variety of transgenic techniques. Together these transformative methodologies grant access to a greater repertoire of genetic diversity as the gene(s) may come from viruses, bacteria, fungi, insects, animals, human beings, unrelated plants or even be artificially derived. Remarkable achievements have been made in the production, characterization, field evaluation and commercialization of transgenic crop varieties worldwide. Likewise, significant advances have been made towards increasing crop yields, improving nutritional quality, enabling crops to be raised under adverse conditions and developing resistance to pests and diseases for sustaining global food and nutritional security. The overarching purpose of this 3-volume work is to summarize the history of crop improvement from a technological perspective but to do so with a forward outlook on further advancement and adaptability to a changing world. Our carefully chosen "case studies of important plant crops" intend to serve a diverse spectrum of audience looking for the right tools to tackle complicated local and global issues.

This book provides essential insights into methods and practices of 'Climate-smart Agriculture,' which is driven by the principles of climate resilience and smart resource use in agricultural production. Climate-smart agriculture is a key policy instrument for achieving poverty eradication and a hunger-free world, as well as mitigating the effects of climate change. This book discusses in detail climate-smart agricultural technologies and practices that can reduce the vulnerability of agricultural systems, improve the livelihoods of farmers and other stakeholders, and reduce the greenhouse gas emissions from crop production and livestock husbandry. The agriculture, forestry and other land use (AFOLU) sector produces roughly 10-12 gigatons of CO2-equivalent per year; therefore, sustainable practices for agriculture and related land use hold immense potential to mitigate climate change. The potential impacts of climate variability and climate change on agriculture are extensively documented and articulated, especially with regard to global and national environmental agendas that call for innovation, transformation and climate-resilient advances in agriculture. As the book demonstrates, climate-smart agriculture offers an excellent tool for boosting agricultural output to feed the growing global population; for reducing greenhouse gases emissions from agriculture and other land use; and for protecting agricultural production systems from the impending dangers of climate change.

Cryopreservation has proven to be an important tool for the storage and conservation of plant genetic resources. This book is a unique resource for plant scientists, providing more than 100 ready-to-use cryopreservation protocols for plant types from algae and bryophytes to a range of flowering plants. It includes techniques for diverse plant parts such as dormant buds, pollen, and apical meristems and for cell types such as suspension and callus cultures.

"The result is a beautiful book with a lot of useful and updated information. I am sure it will be in great demand, and hopefully will help in the further improvement of cassava yields, especially in Africa where it is such an important food crop." Dr Reinhardt Howeler, CIAT Emeritus; author in: Achieving sustainable cultivation of cassava Volume 1 Originating in South America, cassava is now grown in over 100 countries around the world. It is the third most important source of calories in the tropics after rice and maize. Its caloric value, as well as its ability to tolerate dry conditions and poor soils, makes it a key food security crop in developing countries, particularly in Africa. As demand for food grows, there is an urgent need to increase yields in the face of such challenges as climate change, threats from pests and diseases and the need to make cultivation more resource-efficient and sustainable. Drawing on an international range of expertise, this collection focuses on ways of improving the cultivation of cassava at each step in the value chain, from breeding to post-harvest storage. Volume 1 starts by reviewing current issues facing cassava cultivation around the world before discussing methods for sustainable intensification such as rotations, intercropping and more efficient nutrient management. Achieving sustainable cultivation of cassava Volume 1: Cultivation techniques will be a standard reference for agricultural scientists in universities, government and other research centres and companies involved in improving cassava cultivation. It is accompanied by Volume 2 which reviews breeding, pests and diseases.

The book presents a comprehensive study of the impact of policy reforms on output, employment, and productivity growth across sectors of India since 1991. It showcases varied responses from different sectors as they faced different degrees of policy interventions, and challenges or opportunities as regards markets, technology, and availability of skills and other complementary resources. The book also discusses the contributions of the service sector on India's GDP and employment. The book throws light on the phenomena of rising inequality and persistent poverty which continues to shadow and be a hallmark of post-reform India, despite high economic growth. It underlines the failure of these reforms to bring about major change in social and economic organizations and institutions. The book's contents stress on the criticality of addressing these issues as they have a serious potential of jeopardizing the country's ability to maintain high growth momentum. With these pertinent topics, the book would be of interest not only to the research community, but also to policy makers and practitioners of various sectors addressed here.

Many of the earliest books, particularly those dating back to the 1900's and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

In their rapid colonization of soil exposed by fires, floods, and grazing animals, weeds resemble the human specialists we label Emergency Medical Technicians (EMTs). Weeds are the first responders when disasters occur in nature. They occupy bare soil and prevent erosion by wind and water. In extreme cases such as a landslide, weeds are essential to the healing processes that replace the lost soil. Like a Band-Aid on a skinned knee, weeds protect the land while it recovers. Besides protecting the soil after disaster, weeds provide food for wildlife, and some of them provide food and medicine for people. Able to withstand harsh conditions, weeds will proliferate as global warming and other human impacts intensify. Thus, nature's EMTs will increase while all other plants decline. The book provides a succinct definition of weeds according to their form and function in ecosystem processes. The narrative uses a representative set of weed species from a desert location to illustrate the full range of weed characteristics.

Plants require essential nutrients (macronutrients and micronutrients) for normal functioning. Sufficiency range is the levels of nutrients necessary to meet the plant's needs for optimal growth. This range depends on individual plant species and the particular nutrient. Nutrient levels outside of a plant's sufficiency range cause overall crop growth and health to decline, due either to deficiency or toxicity from over-accumulation. Apart from micronutrients (B, Cl, Mn, Fe, Zn, Cu and Mo), Aluminum (Al), cerium (Ce), cobalt (Co), iodine (I), lanthanum (La), sodium (Na), selenium (Se), silicon (Si), titanium (Ti), and vanadium (V) are emerging as novel biostimulants that may enhance crop productivity and nutritional quality. These beneficial elements are not "essential" but when supplied at low dosages, they augment plant growth, development, and yield by stimulating specific molecular, biochemical, and physiological pathways in responses to challenging environments. The book is the first reference volume that approaches plant micronutrient management with the latest biotechnological and omics tools. Expertly curated chapters highlight working solutions as well as open problems and future challenges in plant micronutrient deficiency or toxicity. We believe this book will introduce readers to state-of-the-art developments and research trends in this field.

This book examines comprehensively for the first time, the scope and accuracy of indigenous environmental knowledge. It shows that in some spheres, including agriculture, house design, fuel and water manipulation, the high reputation of local observers is well deserved and often sufficiently insightful to warrant wider imitation. However it also reveals that in certain matters, notably some aspects of health care and wild-species population management, local knowledge systems are conspicuously unsound. Not all the difficulties are of the communities own making, some stem from external factors outside their control. However in either case, remedial measures can be suggested and this book describes, especially for the benefit of practitioners, what steps might be taken in rural communities to improve the quality of life. The possibility of useful transfers of information from local settings to Western ones is not ignored and forms the subject of the book's final chapter.

"Jolene writes with great heart and passion about a dog breed disenfranchised not because of what they are, but because of what we imagine them to be. I love stories that support the underdog, and Jolene's tale of her beloved pit bull terrier is exactly that. It is also a delight to read, and a worthy story to ponder. And you will fall in love with Rumer, I'll promise you that."
-Susan Knilans McElroy, author of "Animals As Teachers" and "Healers and Animals as Guides for the Soul"

"Jolene has truly captured the ways animals enrich and bless our lives in profound ways. Not only is "Angel On My Shoulder" a story of an exceptional, loving pit bull named Rumer, it is on a larger scale the defense of a gentle, loyal breed that has been much maligned and misunderstood. May it help everyone understand both the true nature of the American Pit Bull as well as the true nature of love."
-Katrina Kittle, author of "The Kindness of strangers" and "The Blessings of the Animals"

"Far more than any other breed, the American pit bull represents different things to different people. Badly managed dogs grab headlines because their behavior is atypical; Jolene's experience represents the far less shocking though no less fascinating reality of life with a peaceful, loving, comedic pit bull as 'best friend'. If you enjoy tales of true love, you will value this story."
-Diane Jessup, author of "The Working Pit Bull" and "The Dog Who Spoke With Gods"

On a bitterly cold February day in 1992, a woman named Jolene found herself with a choice to make: the brindle puppy in a kindly stranger's left palm-or the red puppy in his right?

For Jolene Mercadante, a librarian and lifelong animal advocate, this was the first tentative step on a journey that would impact the way she lived the rest of her life. She had no way of knowing how Rumer, a single little soul the size of a sausage, was about to change her life.

Through all of life's great adventures-the perfect five-week-old baby; the lanky, rebellious teenager; the extraordinary, splendid adult-Rumer was a creature of humor and love. She joyfully shattered the unjust "pit bull" stereotypes. She might not have been a heroic rescue dog, a therapy dog, or a war hero; there are other pit bulls who can claim this fame. But Rumer did touch the lives of everyone who knew her, and that made her heroic in her own way.

""She did save us, she did rescue us, and she was our hero in so many ways.""

Rumer was an ordinary dog who lived an ordinary life, but that's what made her extraordinary. This memoir is an unforgettable love story and an uplifting journey brought about by the life of a truly pure and beautiful soul.
