This report is the second in a series that examines the role of natural forests and woodlands in the storage of carbon. Understanding the role of natural ecosystems in carbon storage is an important part of solving the climate change problem. This report presents a landscape-wide green carbon account of the ‘Great Western Woodlands’ (GWW), sixteen million hectares of mostly contiguous natural woody vegetation to the east of the wheatbelt in south-western Western Australia. For the first time, we provide an overview of the vegetation structure, climate, geology and historical land use of the GWW, and examine how these interact to affect the carbon dynamics of this region’s landscape ecosystems. An analysis of time-series of satellite imagery is used to develop a fire history of the GWW since the 1970s. These layers of environmental information, along with field survey data and remotely sensed greenness, are used to construct a spatial model to estimate biomass carbon stocks of the woodlands at the present day, and to infer an upper limit to the carbon sequestration potential of the GWW. A range of management options to enable protection of high quality carbon stocks and restoration of degraded stocks are evaluated.URI

A Critical Companion to Zoosemiotics is the first attempt to systematize the discipline that studies animal communication and signification through its most important and/or problematic terms and concepts, and its most representative scholars. It is a companion, in that it attempts to cover the entire range of key words of the field, and it is critical, in that it aims not only to describe, but also to discuss and problematize such words. The book is conceived for zoosemiotic students, researchers and scholars as a valuable tool for consultation, reference, research and reflection, and it represents an ideal complement for reading and studying zoosemiotic books and essays.

This compendium first reviews regional operational applications of agrometeorology in the form of case studies of agrometeorological services and information. These services prepare farmers of different income levels for extreme weather and climate events and for the use of weather and climate “windows of opportunity” under conditions of a changing climate. Subsequently wide fields of application are covered such as crops (monocropping and multiple cropping, for which aspects of soils, pests, diseases, water, fertilizers and labour are discussed, in so far as they interact with agrometeorological factors), forestry, agroforestry, livestock, and fisheries. These fields are dealt with in a way that the contents form the bedrock material for establishment, improvement, extension and updating of agrometeorological services and information under these changing conditions. Operational supportive methods are finally reviewed and exemplified through case studies of their applications in the above mentioned fields, in approaches related to actual problem solving in agricultural production. This compendium also wants to create a renaissance in the teaching (that is education/training/ extension) of applied agrometeorology at all levels, closer to the livelihood of farmers and other growers.

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.

At the landmark 1992 United Nations Conference on Environment and Development (Earth Summit), solemn resolutions were made both to protect the world’s biodiversity and to co-operate on managing natural forests in a sustainable and ecologically responsible way. If anything, given recent developments in issues such as climate change and poverty, the problem of protecting and sustaining forests should logically have become more important globally. Yet public interest in, and development support for, forest activities have declined and rates of forest loss remain stubbornly high. Why has this happened? This book seeks answers to this question. It examines the often dysfunctional relationships between various members of the international forest constituency, which have so often prevented the formation of consensus. It also explores the tendency to pursue technical and politically convenient ‘fixes’ focused on the internal workings of the forest sector, while ignoring the overwhelming influence of external forces on the fate of forests. The result, all too often, has been programs which benefit a few powerful players and fail to provide real solutions. The book provides a new examination of and perspective on the international forest policy debate. It clarifies the reasons for global forest conflicts and provides insight for future policy development. Including examples from both the developed and developing world, it provides an invaluable resource for researchers and graduate students in forest policy and international relations, as well as a useful reference for policymakers and professionals in the forest sector, the development community and conservationists. With significant global attention now focused on reducing carbon emissions from deforestation and forest degradation (REDD), the authors examine the promise and the potential problems that apply to this initiative.
