        Plant Biodiversity

        Monitoring, Assessment and Conservation

        by Edited by Abid A Ansari, Sarvajeet Singh Gill

        Plants are important components to the ecosystem. They are the base of the food chain and play a significant role in energy flow and biogeochemical cycling of nutrients between terrestrial and aquatic ecosystems. They must constantly fight against the environmental modifications, however, that threaten to cause global species extinction and habitat destruction. A new multidisciplinary science has evolved to deal with the crises confronting biological diversity. It has two goals: first, to investigate human impacts on biological diversity and second, to develop practical approaches to prevent extinction of species. This book is a practical update on our knowledge on monitoring, assessment and conservation of plant biodiversity in aquatic and terrestrial ecosystems and related fields. It includes a general overview of plant biodiversity, investigates a wealth of factors affecting and hindering plant biodiversity before exploring in depth methods of monitoring, assessing and conserving our plant species. Globally relevant, this book is a valuable resource for all researchers, professionals and students of botany and plant biodiversity studies.

        Soil Erosion at Multiple Scales

        Principles and Methods for Assessing Causes and Impacts

        by Edited by Frits W T Penning de Vries, Fahmuddin Agus, John Kerr

        Approaches to research on the causes and impacts of soil erosion have changed significantly over recent years. Whereas biophysical research traditionally utilized small, carefully-managed erosion plots, models and methods are now available to study impacts of broad scale management on the hydrology and water quality of catchments and even river basins. Corresponding research tools have been developed for social and economic analysis at the household, farm and community levels. This book reviews the latest developments in such soil erosion studies. These are considered on a matrix of scales, from plot to river basin, and from farm to national policy. Some chapters review background issues while others consider specific methods. Conclusions of working groups are presented in another chapter. The book is based on papers presented at a workshop held in Indonesia in November 1997, and includes authors from Europe, America, Australia and Asia, as well as from several of the CGIAR centres.

        Soil Biodiversity in Amazonian and Other Brazilian Ecosystems

        by Edited by Fattima M S Moreira, Jose O Siqueira, Lijbert Brussaard

        The loss of biological diversity has become an increased concern over recent years and is now enshrined in international conventions. Most biodiversity in fact occurs in the soil. Soil organisms (especially bacteria, fungi and soil invertebrates) play a major role in the formation of soil structure and are primary agents of decomposition and are drivers of nutrient cycling, and hence agricultural production.This book reviews soil biodiversity in one of the key biodiversity hotspots of the world, i.e. the Amazon and nearby regions of Brazil. It covers both the tropical savannah and rain forests . The work reported is based on a project "Conservation and Sustainable Management of Below-Ground Biodiversity", executed by TSBF-CIAT with co-financing from the Global Environment Facility (GEF) and implementation support from the United Nations Environment Programme (UNEP). The book represents a major contribution to the literature and will interest those in biodiversity conservation, soil scienceand ecology and biodiversity conservation.

        Sustainable Ecological Restoration and Conservation in the Hindu-Kush Himalayan Region

        A Comprehensive Review

        by Zhanhuan Shang, Allan Degen, Devendra Gauchan, Madan Koirala, Muhammad Khalid Rafiq, Awais Iqbal, Binyu Luo, Dawei Zhang, Diwakar Adhikari, Dongmei Li, Furbe Lama, Haonan Guo, Hui Xu, Huma Ali, Jalal Hayat Khan, Jiayi He, Jie Lian, Mei Huang, Monika Ghimire, Narayan Prasad Gaire, Peipei Liu, Qinghui Fang, Ramesh Prasad Sapkota, Ramesh Raj Pant, Rashila Deshar, Ritika K.C, Rui Zhang, Rukhsanda Aziz, Srijana Khanal, Tianyun Qi, Udhab Raj Khadka, Usha Rai, Usman Ali, Wenyin Wang, Xiaoping Jing, Yamuna Ghale, Youyan Liu, Zhen Peng, Zhiqiang Dang

        The years 2021 to 2030 have been designated as "The United Nations Decade on Ecosystem Restoration". Ecological restoration and biodiversity conservation efforts face unprecedented challenges, especially in developing countries and areas, such as the Hindu Kush-Himalayan (HKH) region. This huge HKH region, which includes areas in eight separate countries (Afghanistan, Pakistan, Nepal, India, China, Bangladesh, Myanmar and Bhutan), is a biodiversity hotspot with a vast array of ecosystems, landscapes, peoples and cultures. It is known as one of 'the pulses of the world'. However, the HKH is also the world's largest and poorest mountain region, where landscapes and environments have been severely damaged as a result of climate change and human activities. Coordinating conservation and restoration policies, sharing knowledge and funds, and maintaining livelihoods are major challenges and are in urgent need of improvement. This book details the past and current ecological problems in the HKH region, and the threats and challenges that ecosystems and local people face. It pays special attention to developments of transformative adaptations and presents examples of sustainable conservation and ecological restoration management practices. Three primary questions are addressed: (1) Do the existing conservation strategies of international organizations and government policies really protect ecosystems and solve biodiversity problems? (2) Can these management measures be one-time solutions? and (3) What is the strategic framework and scenario prognosis for the future based on the historical trajectory of ecological conservation and restoration in the region? This book is essential reading for ecologists and conservation biologists involved in large-scale ecological restoration projects, along with practitioners, graduate students, policy makers and international development workers.

        Biodiversity Loss and Conservation in Fragmented Forest Landscapes

        The Forests of Montane Mexico and Temperate South America

        by Adrian C Newton

        Increasing concern surrounding the loss of natural forests and the decline in biodiversity has lead to a rise in research and policy initiatives in recent years. However, interest has focused primarily on lowland tropical rainforests. Tropical montane and temperate rainforests, which face similar pressures from human activities and play major roles in the livelihood of rural communities, are often ignored. Biodiversity Loss and Conservation in Fragmented Forest Landscapes is the product of over 10 years of intensive field research into the changing montane and temperate rainforests of Mexico and South America. By concentrating on these largely overlooked environments, the studies reported allow for comparative analysis across areas and help identify how human disturbance has impacted the biodiversity of all forest types. Chapters incorporate features of landscape ecology, floristic biodiversity, conservation and policy and vary from in-depth investigations of a single study area to integrated examinations across regions.

        Conservation, Revised Edition

        Protecting Our Plant Resources

        by Anne Maczulak, Ph.D.

        Conservation refers to the careful and controlled use of natural resources for the purpose of extending the time they are available as well as retaining biodiversity. Conservation does not prevent the loss of plants, trees, land, water, or habitat; it simply slows the rate of degradation of these things. This updated eBook explores aspects of conservation, particularly the conservation of plant life upon which ecosystems are built. Though students with an interest in ecology assume conservation is a worthwhile endeavor in sustaining the environment, conservation has had a rocky history. Conservation, Revised Edition provides an overview of the successes and failures in striving to protect living natural resources that predate humans on their home continents. Chapters include: Forests and the Water Cycle Analyzing Threats to Forests Tropical Forest Preservation Temperate and Boreal Forest Preservation Desertification Saving Riparian Habitats Reducing Wood Waste.

        Environmental Impacts of Sugar Production

        by Oliver Cheesman

        Pressure from conservationists and increasing regulation, means that environmental considerations are increasingly important for the sugar industry. This book examines the environmental impacts of the sugar industry in relation to the cultivation of sugar crops (cane and beet) and the processing of the raw materials that they yield. These include soil erosion, loss of natural habits leading to a reduction in biodiversity, excessive water consumption, water and air pollution, and runoff and leaching of nutrients. Whilst some of these impacts are essentially generic impacts of agriculture, others, such as those relating to irrigation, are more specific to the cultivation of sugar crops. The book also investigates the utilization of waste materials from sugar production, and explores methods of reducing the environmental impacts of sugar production and processing.

        Nutrition and Feeding Organic Cattle

        by Robert Blair

        Organic cattle farming is on the increase, with consumer demand for organic milk and meat growing yearly. Beginning with an overview of the aims and principles behind organic cattle production, this book presents extensive information about how to feed cattle so that the milk and meat produced meet organic standards, and provides a comprehensive summary of ruminant digestive processes and nutrition. Since the publication of the first edition, global consumers have increasingly become concerned with the sustainability of meat production. Here, Robert Blair considers the interrelationships of sustainable practices and profitability of organic herds, reviewing how to improve forage production and quality, and minimizing the need for supplementary feeding using off-farm ingredients. This new edition also covers: - Managing a recurrent shortage of organic feed ingredients, due to increased GM feed crop cultivation worldwide - Current findings on appropriate breeds and grazing systems for forage-based organic production - Diet-related health issues in organic herds and the effects of organic production on meat and milk quality. Required reading for animal science researchers, advisory personnel that service the organic milk and beef industries and students interested in organic milk and meat production, this book is also a useful resource for organic farming associations, veterinarians, and feed and food industry personnel.
