In the last half century, because of the raising world population and because of the many environmental issues posed by the industrialization, the amount of arable land per person has declined from 0.32 ha in 1961-1963 to 0.21 ha in 1997-1999 and is expected to drop further to 0.16 ha by 2030 and therefore is a severe menace to food security (FAO 2006). At the same time, about 12 million ha of irrigated land in the developing world has lost its productivity due to waterlogging and salinity. Waterlogging is a major problem for plant cultivation in many regions of the world. The reasons are in part due to climatic change that leads to the increased number of precipitations of great intensity, in part to land degradation. Considering India alone, the total area suffering from waterlogging is estimated to be about 3.3 million ha (Bhattacharya 1992), the major causes of waterlogging include super- ous irrigation supplies, seepage losses from canal, impeded sub-surface drainage, and lack of proper land development. In addition, many irrigated areas are s- jected to yield decline because of waterlogging due to inadequate drainage systems. Worldwide, it has been estimated that at least one-tenth of the irrigated cropland suffers from waterlogging.

provides the first in-depth investigation of how non-timber forest products are an integral part of local, national, and global bioeconomies. reveals how essential these products are to creating a greener and more sustainable future will be of great interest to students and scholars of forest and natural resource management, bioeconomics, circular economy and ecological economics more widely

In recent years slugs have become increasingly important, partly because several species are agricultural and horticultural pests and partly because theyhave proved to be useful experimental animals, particularly in the field of neurophysiology. Most of the early works which included slugs were essentially taxonomic but the book byTaylor (1902-1907) contained a great deal of biological information about slugs, some of which is still relevant today. The publication of the book by Runham and Hunter (1970) represented a milestone in slug research, providing a comprehensive survey of current knowledge about slugs. The book by Godan (1983) on snailsand slugswas mainly concerned with theeconomic importanceof theseanimals. The purpose of the present book is to present a review of current knowledgeofthebiologyandecologyofslugs, togetherwith theirstatusand control as pests. Although relatively little is known about the biology and ecology of tropical slugs and most information is taken from work on European slugs, the European pest species have become widely distributed throughout temperate regions and this book should be of interest world wide. It is written as a source of information for people seeking to control slug pests and, also, for those wishing to use slugs for research or teaching purposes. The book is intended particularly to provide a starting point for those beginning research on slugs and an extensive bibliography has been provided.

This volume is devoted to compiling recent advancements, methodological improvements, new processing techniques, integration methods and rigorous applications associated with conceptual techniques on the conservation and monitoring of forest resources for a scientific audience, with a focus on cases and applications in India. The primary objective of the book is to advance the scientific understanding of the recent trends and technological improvements in forest conservation, management and related research themes in forest resources and human-wildlife interactions. The book is organized into five sections: (I) Forest Conservation Ecology (II) Forest Conservation and Society (III) Forest Management (IV) Forest Monitoring using GIS and Remote Sensing and (V) Human Wildlife Conflicts. It covers various research themes related to forestry, wildlife, habitat fragmentation, forest management and human-wildlife conflict research, and therefore will be beneficial to a diverse range of researchers, scientific organizations, wildlife scientists, biologists, ecologists and planners in the fields of wildlife and forestry. The book will further be of use to post-graduates, PhD research scholars, professors, geospatial experts, modellers, foresters, agricultural scientists, biologists, ecologists, environmental consultants and big data compilers.

This book presents modern Bayesian analysis in a format that is accessible to researchers in the fields of ecology, wildlife biology, and natural resource management. Bayesian analysis has undergone a remarkable transformation since the early 1990s. Widespread adoption of Markov chain Monte Carlo techniques has made the Bayesian paradigm the viable alternative to classical statistical procedures for scientific inference. The Bayesian approach has a number of desirable qualities, three chief ones being: i) the mathematical procedure is always the same, allowing the analyst to concentrate on the scientific aspects of the problem; ii) historical information is readily used, when appropriate; and iii) hierarchical models are readily accommodated. This monograph contains numerous worked examples and the requisite computer programs. The latter are easily modified to meet new situations. A primer on probability distributions is also included because these form the basis of Bayesian inference. Researchers and graduate students in Ecology and Natural Resource Management will find this book a valuable reference.

This volume considers current and future challenges for nature law and policy in Europe. Following the Fitness Check evaluation of the Birds and Habitats Directives, in 2017 the EU adopted an Action Plan for nature, people and the economy to rapidly improve the Directives' implementation and accelerate progress towards the EU's biodiversity targets for 2020. More recently, the EU has adopted a Biodiversity Strategy for 2030 and proposed an EU Nature Restoration Law. This book makes a timely contribution by examining the current state of play in light of recent and historical developments, as well as the post-2020 nature law and policy landscape. While evidence suggests that Natura 2000 and the Habitats and Birds Directives have delivered conservation benefits for wildlife in Europe, biodiversity loss continues apace. The book reviews the requirements for an effective international nature conservation system, with reference to the Birds and Habitats Directives. It examines regulatory regimes, current legal issues in the fields of site protection and species protection, the protection of areas outside Natura 2000, recent developments in the EU and the UK, including the implications of Brexit, agriculture and nature conservation, litigation, science and access to justice. Written by leading experts in the field, from a range of stakeholder groups, the volume draws on diverse experiences as well as providing interdisciplinary perspectives. This volume will be essential reading for students and scholars interested in European environmental policy and law, including lawyers, ecologists, environmental scientists, political scientists, natural resource managers, and planners. It will also be of interest to conservation practitioners, policy-makers and NGOs.

Agricultural systems have developed from a research tool in agricultural biology to a discipline that encompasses the whole of the food chain and into institutional and extended education. In this book the current state of agricultural systems is summed up by 14 figures who each deal with their particular specialities. The definitive summaries are now available in book form having been prepared for a conference to commemorate the retirement of a pioneer of agricultural systems, Colin Spedding. The first section deals with the techniques used to develop understanding of plants, animals and the interactions between the two. The book then goes on to discuss systems covering research allocation of the enterprise and farm level, the development of food markets, agricultural strategy formation and insititutional and extension education. Following on from the present state of development each contributor tries to predict the direction which the subject will take in the future.

The existence and competition of trees and shrubs to sustain and put forth growth under varied environmental conditions is dependent on the interactions that occur between the plant metabolic processes and the prevailing environmental conditions. In order to understand the productivity of trees and shrubs, it is a prerequisite to know the experimental techniques of these vital processes. This volume provides a comprehensive presentation of this topic. The first part of this book deals with various aspects of experimental ecophysiology and recent research results of studies on plant pigments, epicuticular wax, leaf nutrients, carbon fixation, all supported by literature. The second part of the volume describes various laboratory techniques such as diffusion, imbibition, calorimetry, atomic absorption, mineral nutrition, nutrition analysis of forage, litterfall chemistry, nutrient cycle, etc. The third and fourth parts deal with advances in the techniques in the development of ecophysiology. The book will serve as an important handbook and resource for students, faculty and teachers, technicians, and researchers and scientists involved in forest science dealing with ecophysiology and biochemistry of woody and crop plants.

Has anyone today any conception of the grandeur, the extent, the million board feet a day production...the entire meaning of the forests of the Pacific Northwest-the "Big Woods"? The photographs alone in this absorbing book will instantly transport the reader into this former world. Here was the greatest stand of Douglas fir timber in existence and here was labor for the Poles, Finns, Swedes and Norskies lured out of the Midwest to convert the mammoth trees into the lumber that helped build the West Coast cities. Ralph Andrews presents a fascinating subject-the hope, courage and tragedy in the lives of the men and women who opened up the dense native forests or as the loggers said "brought daylight into the swamp," and converted the trees into the lumber which built the West Coast cities. Here are many nostalgic scenes showing high climbers, fallers balanced on high springboards, yokes of oxen and up to eight spans of horses dragging logs on skidroad, yokes of oxen and up to eight spans of horses dragging logs on skidroads to flumes, rivers and salt water, early donkey engines, railroads on steep grades, logging camps as well as devastating fires. Andrews' style of writing is graphic and spirited with strong emphasis on human interest.

The Management of Industrial Forest Plantations. Theoretical Foundations and Applications provides a synthesis of current knowledge about industrial forestry management planning processes.

It may provide effective support to education, research and outreach activities that focus on forest industrial plantations management. It may contribute further to support forest managers when developing industrial plantations management plans. The book includes the discussion of applications in 26 Management Planning in Actions boxes. These applications highlight the linkage between theory and practice and the contribution of models, methods and management planning approaches to the efficiency and the effectiveness of industrial plantations management planning.

This book provides researchers and advanced students associated with plant and pharmaceutical sciences with comprehensive information on medicinal trees, including their identification, morphological characteristics, traditional and economic uses, along with the latest research on their medicinal compounds. The text covers the ecological distribution of over 150 trees, which are characterized mainly on the basis of their unique properties and phytochemicals of medicinal importance (i.e., anti-allergic, anti-diabetic, anti-carcinogenic, anti-microbial, and possible anti-HIV compounds). Due to the incredibly large diversity of medicinal trees, it is not possible to cover all within one publication, so trees with unique medicinal properties that are relatively more common in many countries are discussed here in order to make it most informative for a global audience. With over 100 illustrations taken at different stages of plant development, this reference work serves as a tool for tree identification and provides morphological explanations. It includes the latest botanical research, including biochemical advancements in phytochemistry techniques such as chromatographic and spectrometric techniques. In addition, the end of each chapter presents the most up-to-date references for further sources of exploration.

Dendroecologists apply the principles and methods of tree-ring science to address ecological questions and resolve problems related to global environmental change. In this fast-growing field, tree rings are used to investigate forest development and succession, disturbance regimes, ecotone and treeline dynamics and forest decline. This book of global scope highlights state-of-the-science dendroecological contributions to paradigm-shifts in our understanding of ecophysiology, stand dynamics, disturbance interactions, forest decline and ecosystem resilience to global environmental change and is fundamental to better managing our forested ecosystems for the full range of ecosystem goods and services that they provide.

In a world increasingly challenged by the need to integrate and understand highly specialized knowledge in a multidisciplinary way, this book is innovative and perhaps unique in addressing this challenge. It focuses on ideas, strategies, techniques and practices spanning many disciplines at the interface of agriculture with: forestry, horticulture, plant physiology, genetics, ecology, soil science, food science, economics, and the social and environmental sciences as delivered by intensified and enriched agroforestry. Multifunctional Agriculture addresses this complexity, using case studies and insights from the needs of African farmers whose livelihoods are constrained by complex interactions between social, environmental and economic factors and problems underlying agricultural sustainability in Africa. This book, therefore, provides an important resource for those trying to understand the role of agriculture in the achievement of the new Sustainable Development Goals by providing easily implementable, practical and effective methodologies and practices.

The book offers comprehensive coverage of the important topics including: Flower structure and development Development and structure of male and female gametophytes Pollination biology, Fertilization and Self-incompatibility Endosperm, Embryo and Polyembryony Apomixis and Seed Biology

This volume focuses on the tree, as a cultural and biological form, and examines the concept of folk value and its implications for biocultural conservation. Folk value refers to the value of the more-than-human living world to cultural cohesion and survival, as opposed to individual well-being. This field of value, comprising cosmological, aesthetic, eco-erotic, sentimental, mnemonic value and much more, serves as powerful motivation for the local performance of environmental care. The motivation to maintain and conserve ecology for the purpose of cultural survival will be the central focus of this book, as the conditions of the Anthropocene urgently require the identification, understanding and support of enduring, self-perpetuating biocultural associations. The geographical scope is broad with chapters discussing different tree species from the Americas and the Caribbean, East Asia, Eurasia and Australia and Africa. By focusing on the tree, one of the most reliably cross-culturally-valued and cross-culturally-recognized biological forms, and one which invariably defines expansive landscapes, this work illuminates how folk value binds the survival of more-than-human life forms with the survival of specific peoples in the era of biocultural loss, the Anthropocene. As such, this collection of cross-cultural cases of tree folk value represents a low hanging fruit for the larger project of exploring the power of cultural value of the more-than-human living world. This book will be of great interest to students and scholars of conservation, biodiversity, biocultural studies and environmental anthropology.

In 1985 the author fulfilled for himself every forester's ambition - ownership of a woodland to manage and enjoy exactly as he thought fit. With his brother-in-law, he bought a neglected woodland in Hampshire and, with the help of family and friends, has brought it back to a working woodland, employing a combination of ancient and modern rural skills. A Wood of Our Own tells the story of all that has happened since the idea germinated: making the purchase, replanting, encounters with people and animals, the drama of two great gales, unravelling the history of the wood, and selling the timber. Julian Evans, forester for twenty-five years, author of two professional forestry books, and currently Chief Research Officer for the Forestry Commission, combines anecdote, natural history, and professional wisdom in a gripping story. The factual account of the purchase and management of the wood runs alongside an entertaining description of the people, events, and incidents associated with it. Fine cameo line drawings by John White, artist and forester, accompany the text.

The grove, a grouping of trees, intentionally cultivated or found growing wild, has a long diverse history entwined with human settlement, rural practices and the culture and politics of cities. A grove can be a memorial, a place of learning, a site of poetic retreat and philosophy or political encampment, a public park or theatre, a place of hidden pleasures, a symbol of a vanished forest ecology, or a place of gods or other spirits. Yet groves are largely absent from our contemporary vocabulary and rarely included in today's landscape practice, whether urban or rural. Groves are both literal and metaphorical manifestations, ways of defining spaces and ecologies in our cultural life. Since they can add meaning to urban forms and ecologies and contribute meaningfully to the significance of place, critical examination is long overdue. The editors have taken care to ensure that the text is accessible to the general reader as well as specialists.

This book investigates soil ecology and biodiversity for its ability to maintain a balance of beneficial organisms to support plant growth. This subject is discussed by a group of international authors in natural, agricultural and urban systems. The importance of biodiversity per se and, specifically, the feedbacks between the plant and soil biota in mediating soil function are emphasized. Examples are selected from allelopathy and invasive plant species along with the, hitherto overlooked, role of viruses in soil. The book is intended to provide a framework for a holistic understanding of the essential role of soil organisms in promoting plant growth.

Increasing evidence suggests that the composition and spatial configuration - the pattern - of forest landscapes affect many ecological processes, including the movement and persistence of particular species, the susceptibility and spread of disturbances such as fires or pest outbreaks, and the redistribution of matter and nutrients. Understanding these issues is key to the successful management of complex, multifunctional forest landscapes, and landscape ecology, based on a foundation of island bio-geography and meta-population dynamic theories, provides the rationale to deal with this pattern-to-process interaction at different spatial and temporal scales. This carefully edited volume represents a stimulating addition to the international literature on landscape ecology and resource management. It provides key insights into some of the applicable landscape ecological theories that underlie forest management, with a specific focus on how forest management can benefit from landscape ecology, and how landscape ecology can be advanced by tackling challenging problems in forest (landscape) management. It also presents a series of case studies from Europe, Asia, North America, Africa and Australia exploring the issues of disturbance, diversity, management, and scale, and with a specific focus on how human intervention affects forest landscapes and, in turn, how landscapes influence humans and their culture. An important reference for advanced students and researchers in landscape ecology, conservation biology, forest ecology, natural resource management and ecology across multiple scales, the book will also appeal to researchers and practitioners in reserve design, ecological restoration, forest management, landscape planning and landscape architecture.

Rethinking Wilderness and the Wild: Conflict, Conservation and Co-existence examines the complexities surrounding the concept of wilderness. Contemporary wilderness scholarship has tended to fall into two categories: the so-called 'fortress conservation' and 'co-existence' schools of thought. This book, contending that this polarisation has led to a silencing and concealment of alternative perspectives and lines of enquiry, extends beyond these confines and in particular steers away from the dilemmas of paradise or paradox in order to advance an intellectual and policy agenda of plurality and diversity rather than of prescription and definition. Drawing on case studies from Australia, Aoteoroa/New Zealand, the United States and Iceland, and explorations of embodied experience, creative practice, philosophy, and First Nations land management approaches, the assembled chapters examine wilderness ideals, conflicts and human-nature dualities afresh, and examine co-existence and conservation in the Anthropocene in diverse ontological and multidisciplinary ways. By demonstrating a strong commitment to respecting the knowledge and perspectives of Indigenous peoples, this work delivers a more nuanced, ethical and decolonising approach to issues arising from relationships with wilderness. Such a collection is immediately appropriate given the political challenges and social complexities of our time, and the mounting threats to life across the globe. The abiding and uniting logic of the book is to offer a unique and innovative contribution to engender transformations of wilderness scholarship, activism and conservation policy. This text refutes the inherent privileging and exclusionary tactics of dominant modes of enquiry that too often serve to silence non-human and contrary positions. It reveals a multi-faceted and contingent wilderness alive with agency, diversity and possibility. This book will be of great interest to students and scholars of conservation, environmental and natural resource management, Indigenous studies and environmental policy and planning. It will also be of interest to practitioners, policymakers and NGOs involved in conservation, protected environments and environmental governance.
