Book SynopsisEvery bale of hay has a little bit of summer sun stored in the heart of it— learn from a mother-daughter team how hay is made! Feeding her horses one cold and wintry day, a girl thinks about all the hard work that went into the fresh-smelling bales she''s using. The rhyming text and brilliant full-page paintings follow the girl and her mother through the summer as they cut, spread, dry and bale in the fields. Mower blades slice through the grass./A new row falls with every pass./Next we spread the grass to dry./The tedder makes those grasses fly! This celebration of summer, farming, and family, illustrated by Pura Belpré honor artist Joe Cepeda, includes a glossary of haymaking words, and a recipe for making your own switchel— a traditional farm drink, to cool you down in the summer heat. A Bank Street Best Children''s Book of the Year

Book SynopsisThe increase in global population, urbanization and industrialization is resulting in the conversion of cultivated land into wasteland. Providing food from these limited resources to an ever-increasing population is one of the biggest challenges that present agriculturalists and plant scientists are facing. Environmental stresses make this situation even graver. Plants on which mankind is directly or indirectly dependent exhibit various mechanisms for their survival. Adaptability of the plants to changing environment is a matter of concern for plant biologists trying to reach the goal of food security. Despite the induction of several tolerance mechanisms, sensitive plants often fail to withstand these environmental extremes. Using new technological approaches has become essential and imperative.Plant-Environment Interaction: Responses and Approaches to Mitigate Stressthrows light on the changing environment and the sustainability of plants under these conditions.Table of ContentsList of contributors, vii Preface, x About the editors, xii 1 Biotechnological applications to improve salinity stress in wheat, 1Sami ullah Jan, Ghulam Kubra, Mehreen Naz, Ifrah Shafqat, Muhammad Asif Shahzad, Fakiha Afzal andAlvina Gul Kazi 2 Soybean under abiotic stress: Proteomic approach, 28Arafat Abdel Hamed Abdel Latef, Sumaira Jan, Elsayed Fathi Abd-Allah, Bushra Rashid, Riffat John and Parvaiz Ahmad 3 Proteomic analysis of food crops under abiotic stresses in the context of climate change, 43P.

Book SynopsisThis book looks at the current state of food security and climate change, discusses the issues that are affecting them, and the actions required to ensure there will be enough food for the future. By casting a much wider net than most previously published booksto include select novel approaches, techniques, genes from crop diverse genetic resources or relativesit shows how agriculture may still be able to triumph over the very real threat of climate change. Food Security and Climate Change integrates various challenges posed by changing climate, increasing population, sustainability in crop productivity, demand for food grains to sustain food security, and the anticipated future need for nutritious quality foods. It looks at individual factors resulting from climate change, including rising carbon emission levels, increasing temperature, disruptions in rainfall patterns, drought, and their combined impact on planting environments, crop adaptation, production, and management.

Book SynopsisA pioneering urban farmer and MacArthur Genius Award-Winner points the way to building a new food system that can feed- and heal- communities. The son of a sharecropper, Will Allen had no intention of ever becoming a farmer himself. But after years in professional basketball and as an executive for Kentucky Fried Chicken and Procter & Gamble, he cashed in his retirement fund for a two-acre plot just outside Milwaukee's largest public housing project. The area was a food desert with only convenience stores and fast-food restaurants to serve the needs of locals. Despite financial challenges and daunting odds, Allen built the country's preeminent urban farm-a food and educational center that now produces enough produce and fish year-round to feed thousands. Employing young people from the neighboring housing project and community, Growing Power shows how local food systems can help troubled youths, dismantle racism, create jobs, bring urban and rural communities closer together, and improve public health. Today, Allen's organization helps develop community food systems across the country. An eco-classic in the making, The Good Food Revolution is the story of Will's personal journey, the lives he has touched, and a grassroots movement that is changing the way our nation eats.

Book Synopsis“For anyone interested in hemp cultivation or simply learning more about the newest ‘gold rush’ crop, [American Hemp Farmer] is well worth picking up.” ―Publishers Weekly The inside story of the world’s most fascinating and lucrative crop, from gonzo journalist–turned–hemp farmer Doug Fine. Hemp, the non-psychoactive variant of cannabis (or marijuana), has quietly become the fastest industry ever to generate a billion dollars of annual revenue in America. From hemp seed, to hemp fiber, to the currently ubiquitous cannabinoid oil CBD, this resilient, versatile crop is leading the way toward a new, regenerative global economy that contributes to soil and climate restoration. In American Hemp Farmer, maverick journalist and solar-powered goat herder Doug Fine gets his hands dirty growing his own hemp crop and creating his own hemp products. He shares his adventures and misadventures as an independent, regenerative farmer and entrepreneur, whilst laying out a vision for how hemp can help right the wrongs of twentieth-century agriculture - and how you can be a part of it.Trade ReviewLibrary Journal— “An essential book for the aspiring hemp farmer, there is much to consider here for anyone interested in organic farming, drug policy, and community organizing.”Publishers Weekly— “For anyone interested in hemp cultivation or simply learning more about the newest ‘gold rush’ crop, [American Hemp Farmer] is well worth picking up.” Booklist— “A conversational guide for the horticulture geek interested in cultivating hemp. . . . [Fine’s] text is discursive but also helpfully specific and will soothe and encourage any would-be grower.” “A fantastic piece of Americana that shows the way to a sustainable future.”—David Bronner, CEO, Dr. Bronner’s Magic Soaps“With American Hemp Farmer, Doug Fine shows he is not just our preeminent hemp author, he is one of the most important authors of our time. As I’ve watched him leap between tending goats on his Funky Butte Ranch and hemp fields in Hawaii, Oregon, Vermont, and who knows where else, it sometimes occurs to me that he might be the most interesting man alive. The resulting book is an absolute must-read.”—Eric Steenstra, executive director, Vote Hemp“After 83 years of prohibition, cannabis’s emergence from the underground has sparked a gold rush that has every farmer, wannabe farmer, and agricultural entrepreneur rushing to stake their claim. With American Hemp Farmer, Doug Fine makes an incredibly well-written case for a regenerative agriculture–based, small- to mid-scale approach to the industry that prioritizes quality of over quantity, and where soil carbon sequestration is a bottom-line goal. Humorous, timely, and important.”—Jeff Carpenter, coauthor of The Organic Medicinal Herb Farmer“American Hemp Farmer would have been in George Washington’s library. President Washington grew hemp and was a passionate, regenerative agriculturist. Washington sought advice from those that practiced their trade. Doug Fine’s American Hemp Farmer is a scholarly, practical, and impeccably enjoyable work and a must-read for those who cultivate hemp or are interested in leaping in.”—Dean Norton, director of horticulture, Mount Vernon Estate“In his latest, author Doug Fine—a modern day Johnny Hempseed—has painstakingly penned a love letter to the cannabis plant and all those who tend it. Doug details the beneficial and no longer forbidden relationship between cannabis and humanity and how together there is a path to rejuvenate the entire planet. As a state hemp program administrator, I hope every hemp farmer and policymaker reads this book carefully. It details a roadmap for success, for farmers and the planet. And that’s probably because Doug doesn’t just write about hemp, he lives it.”—Cary Giguere, hemp program coordinator, Vermont Agency of Agriculture“As a hempcrete homeowner, I’m proud to keep American Hemp Farmer on my shelf as the must-read book on hemp. Someday we may even see NBA arenas built from hemp. But for now, Doug should be prepared to lose more money at the poker table that sits on the hemp floor of my hemp-paneled card room.”—Don Nelson, two-time NBA Hall of Fame inductee
