The grass family, known as Poaceae, is probably the most important plant family on earth. Grasses were the first food plants to be cultivated by man. Grass crops, such as maize, wheat, rice and sugarcane are still our most important food source to farm animals and the large herds of grazing animals in the wild. The identification of grasses becomes important during land management as the various grass species differ in their grazing value and other ecological functions. Furthermore, weedy grasses react differently to different herbicides and therefore need to be correctly identified. This title, Guide to grasses of southern Africa, is the most comprehensive colour identification guide to the common grasses of southern Africa and includes, among others, the following features: descriptions and illustrations of the 320 most important grasses in southern Africa, an easy-to-use grass identification key, more than 1 000 excellent photographs in full colour, thirteen short, fully illustrated introductory chapters with general information on grasses, common names of grasses in indigenous languages, icons that enable the reader to obtain certain information at a glance.

This text is a synthesis of research in production and management since the inception of the discipline as an agricultural science in the 1930s. All the ecological regions are covered extensively, but the main emphasis is on the three biomes (grassland, savanna and karoo) which produce the bulk of the forage supporting the domestic livestock, conservation and the game farming industries. The book has an audience beyond the borders of South Africa in the grassland and savanna areas which stretch through southern and central Africa.;The text is aimed at students concerned with the management of natural ecosystems and also livestock producers and game ranchers who rely on the veld to feed their animals. The text throughout emphasizes the interpretation and application of research results to the practical situation.;All major aspects of veld production and management are covered in this book. It outlines the physiological and ecological principles on which management is based and which underpin the science. The book presents management options based on these underlying principles before dealing with recommended management procedures in each of the main ecological regions of the country.;The contributions to this book collectively represent a component of the expertise available on issues related to veld management in South Africa. They are veld and animal production researchers, conservation managers and planners working both at a practical level, closely in touch with livestock and game farmers, and at the more theoretical level as teachers at colleges and universities.

Organizing Nature explores how the environment is organized in Canada’s resource-dependent economy. The book examines how particular ecosystem components come to be understood as natural resources and how these resources in turn are used to organize life in Canada. In tracing transitions from "ecosystem component" to "resource," this book weaves together the roles that commodification, Indigenous dispossession, and especially a false nature-society binary play in facilitating the conceptual and material construction of resources. Alice Cohen and Andrew Biro present an alternative to this false nature-society binary: one that sees Canadians and their environments in a constant process of making and remaking each other. Through a series of case studies focused on specific resources – fish, forests, carbon, water, land, and life – the book explores six channels through which this remaking occurs: governments, communities, built environments, culture and ideas, economies, and bodies and identities. Ultimately, Organizing Nature encourages readers to think critically about what is at stake when Canadians (re)produce myths about the false separation between Canadian peoples and their environments.

Die grasfamilie, bekend as Poaceae, is waarskynlik die belangrikste plantfamilie op aarde. Grasse is die eerste voedselplante wat deur mense aangeplant is. Graangewasse, soos mielies, koring, rys en suikerriet (almal grasse), is steeds ons belangrikste bron van energie. Gras, in die vorm van voer, is ook die belangrikste bron van kos vir vee en die groot kuddes grasvreters in die natuur. Die akkurate identifikasie van grasse raak belangrik tydens veldbestuur aangesien grasse ten opsigte van hul weidingswaarde en ander ekologiese funksies verskil. Verder reageer verskillende onkruidgrasse anders op chemise onkruiddoders en moet daarom akkuraat geidentifiseer word. Hierdie boek, Gids tot Grasse van suider-Afrika, is die omvattendste volkleur identifikasiegids tot die algemene grasse in suider-Afrika en sluit onder meer die volgende kenmerke in: Beskrywings en illustrasies van die 320 belangrikste grasse in suider-Afrika; 'n Gebruikersvriendelike indentifikasiesleutel; Meer as 1 000 uitstekende kleurfoto's; Dertien kort en volledig geillustreerde inleidende hoofstukke oor grasse; Algemene grasname in verskeie inheemse tale; Simbole wat die leser in staat stel om inligting met 'n oogopslag te bekom.

When American explorers crossed the Texas Panhandle, they dubbed it part of the ""Great American Desert."" A ""sea of grass,"" the llano appeared empty, flat, and barely habitable. Contemporary developments - cell phone towers, oil rigs, and wind turbines - have only added to this stereotype. Yet in this lyrical ecomemoir, Shelley Armitage charts a unique rediscovery of the largely unknown land, a journey at once deeply personal and far-reaching in its exploration of the connections between memory, spirit, and place. Armitage begins her narrative with the intention to walk the llano from her family farm thirty meandering miles along the Middle Alamosa Creek to the Canadian River. Along the way, she seeks the connection between her father and one of the area's first settlers, Ysabel Gurule, who built his dugout on the banks of the Canadian. Armitage, who grew up nearby in the small town of Vega, finds this act of walking inseparable from the act of listening and writing. ""What does the land say to us?"" she asks as she witnesses human alterations to the landscape - perhaps most catastrophic the continued drainage of the land's most precious resource, the Ogallala Aquifer. Yet the llano's wonders persist: dynamic mesas and canyons, vast flora and fauna, diverse wildlife, rich histories. Armitage recovers the voices of ancient, Native, and Hispano peoples, their stories interwoven with her own: her father's legacy, her mother's decline, a brother's love. The llano holds not only the beauty of ecological surprises but a renewed realization of kinship in a world ever changing. Reminiscent of the work of Terry Tempest Williams and John McPhee, Walking the Llano is both a celebration of an oft-overlooked region and a soaring testimony to the power of the landscape to draw us into greater understanding of ourselves and others by experiencing a deeper connection with the places we inhabit.

Australia's varied grasslands have suffered massive losses and changes since European settlement, and those changes continue under increasingly intensive human pressures for development and agricultural production. The values of native grasslands for conservation of endemic native biodiversity, both flora and fauna, have led to strong interests in the protection of remaining fragments, especially near urban centres, and documentation of the insects and other inhabitants of grasslands spanning tropical to cool temperate parts of the country. Attention to conservation of grassland insects in Australia is relatively recent, but it is increasingly apparent that grasslands harbour many localised and ecologically specialised endemic species. Their conservation necessarily advances from very incomplete documentation, and draws heavily on lessons from the far better-documented grasslands elsewhere, most notably in the northern hemisphere, and undertaken over far longer periods. From those cases, and the extensive background to grassland management to harmonise conservation with production and amenity values through honing use of processes such as grazing, mowing and fire, the needs and priorities for Australia can become clearer, together with needs for grassland restoration at a variety of scales. This book is a broad overview of conservation needs of grassland insects in Australia, drawing on the background provided elsewhere in the world on the responses to disturbances, and the ecological importance, of some key insect groups (notably Orthoptera, Hemiptera and Lepidoptera) to suggest how insect conservation in native, pastoral and urban grasslands may be advanced. The substantial references given for each chapter facilitate entry for non-entomologist grassland managers and stewards to appreciate the diversity and importance of Australia's grassland insects, their vulnerabilities to changes, and the possibilities for conserving them and the wider ecological roles in which they participate.

There is no question that Africa is endowed with abundant natural resources of different magnitudes. However, more than a decade of high commodity prices and new hydrocarbon discoveries across the continent has led countless international organizations, donor agencies, and non-governmental organizations to devote considerable attention to the potential of natural resource-based development. Natural Resource-Based Development in Africa places a particular emphasis on the actors that help us understand the extent to which resources could be transformed into broader developmental outcomes. Based on a wide variety of primary sources and fieldwork, including in-person interviews and participant observations, this collection contributes to both scholarly and policy discussions around the governance and economic development roles of local entrepreneurs, transnational firms, civil society groups, local communities, and government agencies in Africa's natural resource sectors. Natural Resource-Based Development in Africa explores the impact that these actors have on regional trends such as resource nationalism and local procurement policies as well as grassroots-related issues such as poverty, livelihoods, gender equity, development, and human security.

Steppes form one of the largest biomes. Drastic changes in steppe ecology, land use and livelihoods came with the emergence, and again with the collapse, of communist states. Excessive ploughing and vast influx of people into the steppe zone led to a strong decline in nomadic pastoralism in the Soviet Union and China and in severely degraded steppe ecosystems. In Mongolia nomadic pastoralism persisted, but steppes degraded because of strongly increased livestock loads. After the Soviet collapse steppes regenerated on huge tracts of fallow land. Presently, new, restorative steppe land management schemes are applied. On top of all these changes come strong effects of climate change in the northern part of the steppe zone. This book gives an up-to-date overview of changes in ecology, climate and use of the entire Eurasian steppe area and their effects on livelihoods of steppe people. It integrates knowledge that so far was available only in a spectrum of locally used languages.

This unique survey of the environmental history of the grasslands in the United States explores the ecological, social, and economic networks enmeshing humans in this biome over the last 10,000 years. "Treeless, level, and semi-arid." Walter Prescott Webb's famous description of the Great Plains is really only part of their story. From their creation at the end of the Ice Age to the ongoing problems of depopulation, soil erosion, polluted streams, and depleted groundwater aquifers, human interaction with the prairies has often been controversial. Part of ABC-CLIO's Nature and Human Societies series, The Grasslands of the United States: An Environmental History explores the historical and ecological dimensions of human interaction with North America's grasslands. Examining issues as diverse as whether the arrival of the Paleo-Indians led to the extinction of the mammoth and the consequences of industrialization and genetically modified crops, this invaluable reference synthesizes literature from a wide range of authoritative sources to provide a fascinating guide to the environment of this biome. 44 pages of original documents such as the Homestead Act (1862) and the Taylor Grazing Act (1934), Yellow Wolf's concerns with the disappearance of bison (1847), testimony of Kiowas as they sought to protect their reservation, to excerpts from Ron Arnold, one of the main advocates of the Wise Use Movement Each chapter and case study comes complete with corresponding illustrations, maps, charts, or tables

An expert on the buffalo tells the history of this keystone species through extensive research and beautiful photographs. The mere mention of the buffalo instantly brings to mind the vast herds that once roamed the North American continent, and few wild animals captivate our imaginations as much as the buffalo do. Once numbering in the tens of millions, these magnificent creatures played a significant role in structuring the varied ecosystems they occupied. For at least 24,000 years, North American Indigenous Peoples depended upon them, and it was the abundance of buffalo that initially facilitated the dispersal of humankind across the continent. With the arrival of Europeans and their rapacious capacity for wildlife destruction, the buffalo was all but exterminated. In a span of just thirty years during the mid-1800s, buffalo populations plummeted from more than 30 million to just twenty-three. And with them went all of the intricate food webs, the trophic cascades, and the inter-species relationships that had evolved over thousands of years. Despite this brush with extinction, the buffalo survived, and isolated populations are slowly recovering. As this recovery proceeds, the relationships the animals once had with thousands of species are being re-established in a remarkable process of ecological healing. The intricacy of those restored relationships is the subject of this book. Based on author Wes Olson's thirty-five years of working intimately with bison-and featuring 180 stunning, full-colour photographs by Johane Janelle- The Ecological Buffalo is a story that takes the reader on a journey to understand the myriad connections this keystone species has with the Great Plains.

With large-scale, global declines in many species of plants and animals and other disruptions such as climate change and urbanization, we must learn how humans and other species can coexist with one another. In a case study of urban biodiversity, Erik Kiviat and Kristi MacDonald present two decades of data and assessment of the habitats and biota of the New Jersey Meadowlands. Urban Biodiversity: The Natural History of New Jersey Meadowlands documents the mammals, birds, reptiles, amphibians, fish, butterflies, bees, dragonflies, seed plants, mosses, and lichens of the Meadowlands region and the patterns of their occurrence. The work records the natural history of an urban-industrial region, helping decision makers foster the biodiversity that thrives in cities and giving planners tools to reduce the biological degradation that occurs with urbanization.

This collection features five peer-reviewed literature reviews on using crops as biofuel. The first chapter reviews the key issues and challenges faced when expanding sugarcane cultivation for bioenergy, primarily, competition with food crops, loss of biodiversity, water, air and soil pollution, as well as a potential increase in pest problems. The second chapter describes current technologies and constraints of biodiesel production, including the need for a consistent supply of feedstock to ensure a sustainable biodiesel industry. The chapter also examines life cycle assessment (LCA) of canola/rapeseed biodiesel production. The third chapter addresses the sustainability of biofuels derived from palm oil and discusses the impact of their production on our ecosystems. The chapter also reviews the economics of biofuel and the levels of governmental support needed for sustainable production. The fourth chapter examines the potential of varying grassland types for biomass production. It details the options for use of grassland biomass, citing its suitability for combustion, pyrolysis, biorefining and for use in bioenergy applications. The final chapter reviews best agronomic practices for increasing overall biomass output in the face of pressing environmental changes. It also utilises the LCA framework to review strategies for crop improvement, such as crop rotations.

Canada and the United States share the world's longest international border. For those living in the immediate vicinity of the Canadian side of the border, the events of 9/11 were a turning point in their relationship with their communities, their American neighbours and government officials. Borderline Canadianness offers a unique ethnographic approach to Canadian border life. The accounts of local residents, taken from interviews and press reports in Ontario's Niagara region, demonstrate how borders and everyday nationalism are articulated in complex ways across region, class, race, and gender. Jane Helleiner's examination begins with a focus on the "de-bordering" initiated by NAFTA and concludes with the "re-bordering" as a result of the 9/11 attacks. Her accounts of border life reveals disconnects between elite border projects and the concerns of ordinary citizens as well as differing views on national belonging. Helleiner has produced a work that illuminates the complexities and inequalities of borders and nationalism in a globalized world.

Shortlisted for the 2015 Wainwright Prize In this journey across England's most forbidding and mysterious terrain, William Atkins takes the reader from south to north, exploring moorland's uniquely captivating position in our history, literature and psyche. Atkins' journey is full of encounters, busy with the voices of the moors, past and present. He shows us that, while the fierce terrains we associate with Wuthering Heights and The Hound of the Baskervilles are very human landscapes, the moors remain daunting and defiant, standing steadfast against the passage of time.

Colonial Geography charts changes in conceptions of the relationship between people and landscapes in mainland Tanzania during the German colonial period. In German minds, colonial development would depend on the relationship between East Africans and the landscape. Colonial Geography argues that the most important element in German imperialism was not its violence but its attempts to apply racial thinking to the mastery and control of space. Utilizing approaches drawn from critical geography, the book argues that the development of a representational space of empire had serious consequences for German colonialism and the population of East Africa. Colonial Geography shows how spatial thinking shaped ideas about race and empire in the period of New Imperialism.

This comprehensive book unravels the complexities of the grassland systems of Mongolia and northern China to identify the ways in which policies and incentives can be strengthened to improve grassland condition and herder livelihoods. Through an interdisciplinary lens, combining environmental economics and grassland science, contributors unpack the preferences, attitudes and behavioural responses of Asian grassland actors to new and alternative policies. Offering a comparative analysis of policies and incentives in China and Mongolia, chapters focus on understanding ex ante behavioural responses, arguing convincingly for a mix of incentives and associated policy measures that can both improve grassland conditions and align with the preferences of herders and officials. Featuring a unique interdisciplinary focus and comparative approach, this book is crucial reading for grassland and rangeland scientists in China, Mongolia and beyond as well as grassland officials seeking new policies and a better understanding of their impact. Academics and researchers of the environment and ecology in China, Mongolia and Asia more broadly will also find this book a fascinating insight into environmental livelihoods and contemporary grassland experiences.

Originally published in 1984 Nature's Ideological Language examines the common ideological roots of environmental reclamation and nature preservation. In the general context of European, British and American historical experience, the Jutland heaths of Denmark are taken as a concrete example for a general critique of European and American policy concerning the use of landscape. Two sets of contradictions are highlighted: ideological and practical between development and preservation; and those between scientific, historical aesthetic and recreational motivation for preservation. The book is based on a study of the Jutland heath from 1750 to the present, focusing on the Danish perception of the area as expressed in literary art and in economic journals, topographies and government reports. Against this background, the development of the modern conception of nature is traced and its ideological implications and planning consequences discussed. As a study of humanistic geography, this book will be of interest to geographers, conservationists and planners.

Kevin E. Trenberth emphasizes the fundamental role of energy flows in the climate system and anthropogenic climate change. The distribution of heat, or more generally, energy, is the main determinant of weather patterns in the atmosphere and their impacts. The topics addressed cover many facets of climate and the climate crisis. These include the diurnal cycle; the seasons; energy differences between the continents and the oceans, the poles and the tropics; interannual variability such as Nino; natural decadal variability; and ice ages. Human-induced climate change rides on and interacts with all of these natural phenomena, and the result is an unevenly warming planet and changing weather extremes. The book emphasizes the need to not only slow or stop climate change, but also to better prepare for it and build resilience. Students, researchers, and professionals from a wide range of backgrounds will benefit from this deeper understanding of climate change.

An interdisciplinary text on the world's savannas, covering the geography, ecology, economics and politics of savanna regions. Savannas are a distinct vegetation type, covering a third of the world's land surface area and supporting a fifth of the world's population. There has been a wide range of literature on the subject, but the majority of work has focused on the ecology or development of savanna areas, ignoring the wider interdisciplinary issues affecting contemporary savannas. World Savannas aims to buck this trend, providing students with an up-to-date and comprehensive introduction to the global importance of savannas.

Following the destruction of 95% of meadows during the twentieth century, there is an urgent need to understand what little unspoiled habitat remains in order to plan the management and restoration of existing sites, as well as re-creating future grassland habitats. This book is a much-needed guide to grassland restoration and management. Providing a thorough overview of recent research on grassland restoration and its implications for practical grassland restoration and management, it introduces grassland communities and the wildlife they support, including examples of species of conservation concern, and considers the management of semi-natural grassland habitats with particular emphasis on drier grassland habitats. Chapters cover: - Grassland character and communities - Introduction to grassland wildlife - Managing semi-natural grassland - Grassland restoration - threats and challenges - Opportunities in grassland restoration - Plant material for grassland restoration - Defining success in grassland restoration. A variety of management techniques are examined, including soil amendment, cultivation, harvesting and maintenance in creating suitable conditions for the successful restoration of species-rich grasslands. It is essential reading for conservationists, site owners or managers, practitioners, conservation organizations and students of ecological restoration with an interest in the creation of new grassland habitats, the restoration of semi-natural grassland, as well as the continuing management of semi-natural (unimproved) grassland communities.
