This book covers biodiversity conservation under special consideration of the challenges in the global south with particular attention being paid to consider the existing conservation challenges in relation to the study area in Ethiopia. Key issues are addressed, such as the current and future threats to plant biodiversity in Ethiopia, as well as the single large or several small conservation approaches and which approach is feasible for Ethiopia. Furthermore, an innovative approach was developed that enhances ecological connectivity and promotes ecological restoration through community involvement. The book also covers why a systematic conservation planning approach is important and should be used in new protected area establishments, and also looks at the trends of plant ecology research over the past five decades, revealing research gaps and suggesting future research topics. Despite its focus on Ethiopian plant diversity, abundant examples were used from different continents making this book attractive to global readers. It will be of interest for policy- and decision-makers in the conservation sector, researchers interested in biodiversity, climate change, conservation and sustainable use of natural resources, and would be a valuable resource for university students.

This book provides complete, comprehensive, and broad subject-based reviews for students, teachers, researchers, policymakers, conservationists, and NGOs interested in the biodiversity and conservation of woody plants. Forests cover approximately 31 percent of the world’s total landmass; 93 percent is natural forest and only 7 percent consists of planted trees. Forest decline is progressing at an alarming rate worldwide. In addition to human activities (logging, deforestation, and exploiting forest lands for agriculture and industrial use), a number of other factors – including pests and diseases, drought, soil acidity, radiation, and ozone – are cumulatively contributing to global forest decline. The present situation forces us to focus on forest conservation strategies for the present and future. Gene conservation and maintaining genetic diversity in forest ecosystems are crucial to the preservation of forest genetic resources. This calls for integrated action to implement both the in situ (on site) preservation of forest stands and ex situ (distant from the original site) strategies for the conservation of woody plants’ genetic resources. Selected priority areas include: 1) assessing patterns of genetic diversity and threats, 2) understanding the biological processes regulating genetic diversity, 3) assessing the impact of human activities and climate change on genetic diversity, and 5) finding methods for prioritizing species and populations for the conservation of forest trees genetic resources. All chapters were written by leading scientists in their respective fields, which include: woody plant diversity, ecology and evolution; assessment of genetic diversity in forest tree populations; conservation planning under climate change; and in situ and ex situ strategies, including biotechnological approaches, for the conservation of woody plants genetic resources.

One of the world centers of crop evolution and origin, Ethiopia has long been recognized as an important area of diversity for several major and various minor crops. Based on an international conference held in Addis Ababa, this book describes how plant genetic diversity in Ethiopia is of vital importance in breeding new varieties of crops with desirable characteristics, such as increased resistance to pests and diseases and greater adaptation to heat and drought. The three main sections in the book consider the Ethiopian center of diversity, germ plasm or genetic material collection and conservation in Ethiopia, and the evaluation and utilization of Ethiopian genetic resources. A broad range of food and feed crops and plants of medicinal and industrial importance are discussed, both at a national and international level. A brief account of conservation strategies and gene bank problems unique to Ethiopia is also given. The importance of Ethiopia's plant genetic resources to world agriculture has been demonstrated on more than one occasion. Plant breeders, geneticists, and botanists throughout the world will, therefore, find this unique book a valuable source of information and an essential reference work.

What is a beautiful garden to southern Ethiopian farmers? Anchored in the author’s perceptual approach to the people, plants, land, and food, The Edible Gardens of Ethiopia opens a window into the simple beauty and ecological vitality of an ensete garden. The ensete plant is only one among the many “unloved” crops that are marginalized and pushed close to disappearance by the advance of farming modernization and monocultural thinking. And yet its human companions, caught in a symbiotic and sensuous dialogue with the plant, still relate to each exemplar as having individual appearance, sensibility, charisma, and taste, as an epiphany of beauty and prosperity, and even believe that the plant can feel pain. Here a different story is recounted of these human-plant communities, one of reciprocal love at times practiced in an act of secrecy. The plot unfolds from the subversive and tasteful dimensions of gardening for subsistence and cooking in the garden of ensete through reflections on the cultural and edible dimensions of biodiversity to embrace hunger and beauty as absorbing aesthetic experiences in small-scale agriculture. Through this story, the reader will enter the material and spiritual world of ensete and contemplate it as a modest yet inspiring example of hope in rapidly deteriorating landscapes. Based on prolonged engagement with this “virtuous” plant of southwestern Ethiopia, this book provides a nuanced reading of the ensete ventricosum (avant-)garden and explores how the life in tiny, diverse, and womanly plots offers alternative visions of nature, food policy, and conservation efforts.

Over seven chapters, this book helps readers to integrate knowledge of plant anatomy, physiology, and morphogenesis as well as consider the conditions of the different environments to which plants are exposed. It highlights the importance of knowledge of the anatomy of plant tissues for different applications. In addition to the variety of physiological studies presented here, the book also emphasizes anatomical studies in botanical quality control of medicinal herbs with human health benefits. It is reflected in this book that studies on plant structure have greatly benefited from the new approaches and techniques available today.

Early anthropological evidence for plant use as medicine is 60,000 years old as reported from the Neanderthal grave in Iraq. The importance of plants as medicine is further supported by archeological evidence from Asia and the Middle East. Today, around 1.4 billion people in South Asia alone have no access to modern health care, and rely instead on traditional medicine to alleviate various symptoms. On a global basis, approximately 50 to 80 thousand plant species are used either natively or as pharmaceutical derivatives for life-threatening conditions that include diabetes, hypertension and cancers. As the demand for plant-based medicine rises, there is an unmet need to investigate the quality, safety and efficacy of these herbals by the “scientific methods”. Current research on drug discovery from medicinal plants involves a multifaceted approach combining botanical, phytochemical, analytical, and molecular techniques. For instance, high throughput robotic screens have been developed by industry; it is now possible to carry out 50,000 tests per day in the search for compounds, which act on a key enzyme or a subset of receptors. This and other bioassays thus offer hope that one may eventually identify compounds for treating a variety of diseases or conditions. However, drug development from natural products is not without its problems. Frequent challenges encountered include the procurement of raw materials, the selection and implementation of appropriate high-throughput bioassays, and the scaling-up of preparative procedures. Research scientists should therefore arm themselves with the right tools and knowledge in order to harness the vast potentials of plant-based therapeutics. The main objective of Plant and Human Health is to serve as a comprehensive guide for this endeavor. Volume 1 highlights how humans from specific areas or cultures use indigenous plants. Despite technological developments, herbal drugs still occupy a preferential place in a majority of the population in the third world and have slowly taken roots as alternative medicine in the West. The integration of modern science with traditional uses of herbal drugs is important for our understanding of this ethnobotanical relationship. Volume 2 deals with the phytochemical and molecular characterization of herbal medicine. Specifically, it focuess on the secondary metabolic compounds, which afford protection against diseases. Lastly, Volume 3 discusses the physiological mechanisms by which the active ingredients of medicinal plants serve to improve human health. Together this three-volume collection intends to bridge the gap for herbalists, traditional and modern medical practitioners, and students and researchers in botany and horticulture.
