Download or read book Conifers of the World written by James E. Eckenwalder and published by Timber Press. This book was released on 2009-11-14 with total page 745 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researched for more than three decades, this definitive work provides up-to-date descriptions of all the true conifers of the world, including 545 species of trees and shrubs. Written for accessibility to both horticultural and botanical audiences, it is the first comprehensive update of conifer taxonomy in nearly a century. Noted conifer taxonomist James E. Eckenwalder also discusses the relationships among the groups, practical usages, champion trees, fossil occurrences, and biology. New identification guides for the families and genera are based whenever possible on foliage features and thus should be easier to use than traditional conifer keys, which focus on seasonal, and often microscopic, cone characters. Eckenwalder shares the reasoning behind his taxonomic decisions, many of which are unique to this book, reflecting a comprehensive reevaluation of conifer classification. He also outlines the features sought in cultivars of each genus, particular cultivation concerns, and conifers recommended for cultivation under various conditions and to achieve different effects. Some 3,000 cultivars have been available in recent times, more than five times the total number of conifer species. Several hundred original illustrations include drawings of the seed cones for all genera as well as for representative species. Maps of the natural distribution of each genus allow for easy comparison of ranges. Handsome black-and-white photographs of species in their natural habitats and attractive color photos further enrich the volume. More than 100 images reproduce foliage of many genera as an aid in identification. With its unprecedented attention to detail and extensive bibliography, this major work is an essential reference for botanists, naturalists, and horticulturists.

Download or read book Mountain agriculture Opportunities for harnessing Zero Hunger in Asia written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-08-07 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountain food security and nutrition are core issues that can contribute positively to the achievement of the Sustainable Development Goals but paradoxically are often ignored in Zero Hunger and poverty reduction-related agenda. Under the overall leadership of José Graziano da Silva, the Former Director-General of FAO, sustainable mountain agriculture development is set as a priority in Asia and the Pacific, to effectively address this issue and assist Member Countries in tackling food insecurity and malnutrition in mountain regions. This comprehensive publication is the first of its kind that focuses on the multidimensional status, challenges, opportunities and solutions of sustainable mountain agriculture development for Zero Hunger in Asia. This publication is building on the ‘International Workshop and Regional Expert Consultation on Mountain Agriculture Development and Food Security and Nutrition Governance’, held by FAO RAP and UIR in November 2018 Beijing, in collaboration with partners from national governments, national agriculture institutes, universities, international organizations and international research institutes. The publication provides analysis with evidence on how mountain agriculture could contribute to satisfying all four dimensions of food security, to transform food systems to be nutrition-sensitive, climate-resilient, economically-viable and locally adaptable. From this food system perspective, the priority should be given to focus on specialty mountain product identification (e.g. Future Smart Food), production, processing, marketing and consumption, which would effectively expose the potential of mountain agriculture to contribute to Zero Hunger and poverty reduction. In addition, eight Asian country case studies not only identify context-specific challenges within biophysical-technical, policy, socio-economic and institutional dimensions.
Download or read book Forgotten Agricultural Heritage written by Parviz Koohafkan and published by Routledge. This book was released on 2016-11-25 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contemporary agriculture is often criticized for its industrial scale, adverse effects on nutrition, rural employment and the environment, and its disconnectedness from nature and culture. Yet there are many examples of traditional smaller scale systems that have survived the test of time and provide more sustainable solutions while still maintaining food security in an era of climate change. This book provides a unique compilation of this forgotten agricultural heritage and is based on objective scientific evaluation and evidence of the value of these systems for present and future generations. The authors refer to many of these systems as Globally Important Agricultural Heritage Systems (GIAHS) and show how they are related to the concepts of heritage and the World Heritage Convention. They demonstrate how GIAHS based on family farms, traditional indigenous knowledge and agroecological principles can contribute to food and nutrition security and the maintenance of agro-biodiversity and environmental resilience, as well as sustain local cultures, economies and societies. Two substantial chapters are devoted to descriptions and assessments of some 50 examples of designated and potential GIAHS from around the world, including rice-fish culture in China, mountain terrace systems in Asia, coffee agroforestry in Latin America, irrigation systems and land and water management in Iran and India, pastoralism in East Africa, and the dehesa agrosilvopastoral system of Spain and Portugal. The book concludes by providing policy and technical solutions for sustainable agriculture and rural development through the enhancement of these systems.
