"This is a reference book containing information on over 200 species, including where each is proclaimed and what the legal requirements are for its control. Each weed has a detailed description and colour photograph to make identification straightforward." - product description.
Over-two thirds of the U.S. population is allergic to poison oak, poison ivy, or a related plant. These and many other common plants in our homes, fields, and gardens are irritants that cause misery to many. But surprisingly, there has never been a general guide to help raise awareness of them--and to help avoid them. This new book reviews the history, occurrence, classification, toxicity, and health aspects of all the major allergenic and irritant species.
Weeds are successful plants, but on their own terms. Looking at weeds from an ecological viewpoint, emphasising the way in which one species interacts with others, the authors show that weeds are questionable mainly in that they are out-of-place.
Weeds hold an enigmatic and sometimes-controversial place in agriculture, where they are generally reviled, grudgingly tolerated, and occasionally admired. In most cases, growers make considerable effort to reduce the negative economic impact of weeds because they compete with crops for resources and hinder field operations, thereby affecting crop productivity and quality, and ultimately the sustainability of agriculture. Weed control in production agriculture is commonly achieved through the integration of chemical, biological, and mechanical management methods. Chemicals (herbicides) usually inhibit the growth and establishment of weed plants by interfering with various physiological and biochemical pathways. Biological methods include crop competition, smother crops, rotation crops, and allelopathy, as well as specific insect predators and plant pathogens. Mechanical methods encompass an array of tools from short handled hoes to sophisticated video-guided robotic machines. Integrating these technologies, in order to relieve the negative impacts of weeds on crop production in a way that allows growers to optimize profits and preserve human health and the environment, is the science of weed management.
Increase in world population, extreme weather conditions, decrease in fresh water supplies, and changes of dietary habits are major issues that affect global food security. We are expected to face the challenges of land use by 2050 because population will reach 9 billion while agricultural productivity losses are expected due to overuse of lands. How can we feed the next generations in a manner that respects our finite natural resources? Managing our resources in a sustainable way have only begun for selected crops. Much remains to be done to increase food yield. Cropping practices capable of sustainable production need to be elaborated, especially in fragile ecosystems. Typical applications will include the improvement and use of genetic resources; crop management and diversification; diffusion of improved varieties; development of cropping systems; sustainable cropping systems for areas prone to environmental degradation; use of agro-ecological data for crop production forecasting; and networks for regional coordination, and data exchange. The impetus behind this book is to bring attention to a cropping system that bears direct relevance to sustainable agriculture and food security. “Underutilized” crops are found in numerous agricultural ecosystems and often survive mainly in marginal areas. It is timely to review their status because, in recent decades, scientific and economic interests have emerged which focus on lesser-known cultivated species. Underutilized crops have a great potential to alleviate hunger directly, through increasing food production in challenging environments where major crops are severely limited. “Global Perspectives on Underutilized Crops” is therefore topical and highlights the unmet agricultural challenges that we face today. This book is an important resource for students and researchers of crop science and agricultural policy makers.
Now back in print. Plants of Western New South Wales grew from the long experience and expertise which the authors acquired during their employment with their respective organisations in the arid and semi-arid pastoral areas of the State. Each author became aware of the need for a comprehensive record illustrating and describing the great array of plants in the area. The need was identified both for people involved in research and advisory services, and particularly for the landholders who need to manage the plants for their livelihood. The book is a landmark because it draws together all of the existing knowledge of plants from the area, adds to it the extensive collections and research of the authors and presents the whole as a comprehensive collation and description of the plants of the dry pastoral portion of the State. Because of its comprehensive nature, the work is significant to pastoralists and people concerned with plants throughout Australia. The 1992 edition of Plants of Western New South Wales has been reprinted and published by CSIRO PUBLISHING with a one page appendix giving website addresses of various herbaria in Australia where the reader can readily access up-to-date information on botanical name changes.
Geological Heritage has very diverse elements, both for its intrinsic nature and for its social and scientific significance. These elements have a scientific dimension (stratigraphic, geomorphological, lithological, paleontological, etc.) and a landscape dimension, both with implications for territorial management. In territorial management and planning, it is essential to carry out inventory and cataloging of places of natural and social interest to establish a comprehensive policy. The identification and valuation of the geological and biological heritage, and their interaction in the landscape should favor the conservation and preservation of this natural and historical heritage. Sustainable development implies rational use that prevents the degradation or loss of these unique environments of the natural environment as well as a dissemination and awareness of landscape resources for a better understanding and enjoyment, integrating activities of both environmental education and nature tourism.
