Book Description
The central theme of this text is that the introduction of agricultural and pastoral systems in Australia's temperate grazing lands has often created dynamic and sustaining ecosystems. The author argues that while these ecosystems are not native, and while they are not problem-free, they have made an immense contribution to the building of the country - largely in terms of increased soil fertility. This has been done by adding trace elements, superphosphate and legumes, thereby developing a new ecosystem, probably just as self-sustaining as the one it replaced.

Book Description
Climate variability has major impacts in many parts of the world, including Australia. Developments in understanding of the El Niño - Southern Oscillation Phenomenon have introduced some skill in seasonal to inter-annual climate forecasting. Can this skill be harnessed to advantage? Or do we just continue to observe these impacts? How does a decision-maker managing an agricultural or natural ecosystem modify decisions in response to a skillful, but imprecise, seasonal climate forecast? Using Australian experience as a basis, this book focuses on these questions in pursuing means to better manage climate risks. The state of the science in climate forecasting is reviewed before considering detailed examples of applications to: farm scale agricultural decisions (such as management of cropping and grazing systems); regional and national scale agricultural decisions (such as commodity trading and government policy); and natural systems (such as water resources, pests and diseases, and natural fauna). Many of the examples highlight the participatory and inter-disciplinary approach required among decision-makers, resource systems scientists/analysts, and climate scientists to bring about the effective applications. The experiences discussed provide valuable insights beyond the geographical and disciplinary focus of this book. The book is ideally suited to professionals and postgraduate students in ecology, agricultural climatology, environmental planning, and climate science.

Book Description
Food security and environmental conservation are two of the greatest challenges facing the world today. It is predicted that food production must increase by at least 70% before 2050 to support continued population growth, though the size of the world's agricultural area will remain essentially unchanged. This updated and thoroughly revised second edition provides in-depth coverage of the impact of environmental conditions and management on crops, resource requirements for productivity and effects on soil resources. The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology and morphology. System concepts are explored in detail throughout the book, giving emphasis to quantitative approaches, management strategies and tactics employed by farmers, and associated environmental issues. Drawing on key examples and highlighting the role of science, technology and economic conditions in determining management strategies, this book is suitable for agriculturalists, ecologists and environmental scientists.

Book Description
Curating the Future: Museums, Communities and Climate Change explores the way museums tackle the broad global issue of climate change. It explores the power of real objects and collections to stir hearts and minds, to engage communities affected by change. Museums work through exhibitions, events, and specific collection projects to reach different communities in different ways. The book emphasises the moral responsibilities of museums to address climate change, not just by communicating science but also by enabling people already affected by changes to find their own ways of living with global warming. There are museums of natural history, of art and of social history. The focus of this book is the museum communities, like those in the Pacific, who have to find new ways to express their culture in a new place. The book considers how collections in museums might help future generations stay in touch with their culture, even where they have left their place. It asks what should the people of the present be collecting for museums in a climate-changed future? The book is rich with practical museum experience and detailed projects, as well as critical and philosophical analyses about where a museum can intervene to speak to this great conundrum of our times. Curating the Future is essential reading for all those working in museums and grappling with how to talk about climate change. It also has academic applications in courses of museology and museum studies, cultural studies, heritage studies, digital humanities, design, anthropology, and environmental humanities.

Book Description
In its early days, agroforestry may have been viewed as the domain of the 'landcare enthusiast'. Today, integrating trees and shrubs into productive farming systems is seen as a core principle of sustainable agriculture. Agroforestry for Natural Resource Management provides the foundation for an understanding of agroforestry practice in both high and low rainfall zones across Australia. Three major areas are discussed: environmental functions of trees in the landscape (ecosystem mimicry, hydrology, protection of crops, animals and soil, biodiversity, aesthetics); productive functions of trees (timber, firewood, pulp, fodder, integrated multi-products); and the implementation of agroforestry (design, evaluation, establishment, adoption, policy support). The book also includes a DVD that features videos on forest measurement and harvesting, a Farm Forestry Toolbox and many regionally specific agroforestry resources. Written by leading researchers and practitioners from around Australia, Agroforestry for Natural Resource Management will be an essential resource for students in agroforestry courses, as well as a valuable introduction to the field for professionals in related areas.

Book Description
Native temperate grasslands are Australia’s most threatened ecosystems. Grasslands have been eliminated from across much of their former extent and continue to be threatened by urban expansion, agricultural intensification, weed invasion and the uncertain impacts of climate change. Research, however, is showing us new ways to manage grasslands, and techniques for restoration are advancing. The importance of ongoing stewardship also means it is vital to develop new strategies to encourage a broader cross-section of society to understand and appreciate native grasslands and their ecology. Land of Sweeping Plains synthesises the scientific literature in a readily accessible manner and includes a wealth of practical experience held by policy makers, farmers, community activists and on-ground grassland managers. It aims to provide all involved in grassland management and restoration with the technical information necessary to conserve and enhance native grasslands. For readers without the responsibility of management, such as students and those interested in biodiversity conservation, it provides a detailed understanding of native grassland ecology, management challenges and solutions and, importantly, inspiration to engage with this critically endangered ecosystem. Practical, easy to read and richly illustrated, this book brings together the grassland knowledge of experts in ethnobotany, ecology, monitoring, planning, environmental psychology, community engagement, flora and fauna management, environmental restoration, agronomy, landscape architecture and urban design.
