Book excerpt: Management of New Zealand's environment needs to be based on sound knowledge. Natural resource managers and policy makers now have at their fingertips the first comprehensive assessment of the state of ecosystem services - the benefits people obtain from nature - in this country. More than 100 of New Zealand's leading scientists and academics have penned the 36 chapter for the new 540-page book. Ecosystem services are categorised as 'provisioning', such as food, timber and freshwater; 'regulating', such as air quality, climate and pest regulation; 'cultural' such as recreation and sense of belonging; and 'supporting', such as soil quality and natural habitat resistance to weeds.

Download or read book The UK Pesticide Guide 2020 written by Martin A. Lainsbury and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: By far the biggest change to The UK Pesticide Guide in 2020 is the loss of a number of active ingredients that have been fundamental to many crop protection programmes. The final use-up of chlorothalonil formulations; propiconazole, fenpropimorph, chloridazon and diquat occurs in 2020 but there are also a few exciting new additions. Aclonifen is a new residual herbicide for use in potatoes that already has a number of EAMUs for use in minor crops. BASF is launching its new triazole, mefentrifluconazole, which promises to restore full triazole activity, at least initially. On the insecticide front the new active ingredient from Corteva agriscience, sulfoxaflor, is now listed for use in Cucurbitae and ornamentals under full protection for control of aphids and whitefly.

Download or read book Channelized Rivers written by Andrew Brookes and published by John Wiley & Sons. This book was released on 1988 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Channelized Rivers Perspectives for Environmental Management Andrew Brookes Environmental Consultant, Reading, UK For centuries engineers have modified river channels in order to control floods, drain land, prevent erosion and improve navigation. The natural shape of many rivers has been dramatically changed, often with dire environmental consequences. This book demonstrates the role fluvial geomorphology can play in the design of river channels, both to lessen environmental impact and to enhance the success of channelization schemes. It considers the physical and biological impacts of channelization, the repercussions downstream and in the adjacent floodplain. Revised procedures and designs are proposed which minimize harsh environmental impacts. The interdisciplinary approach of the book offers river managers the opportunity to make more environmentally sensitive decisions in the course of their work. The book will be of great interest to geomorphologists, biologists and civil engineers working in the water industry.

Download or read book The Seine River Basin written by Nicolas Flipo and published by Springer Nature. This book was released on 2021-01-30 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book reviews the water-agro-food and socio-eco-system of the Seine River basin (76,000 km2), and offers a historical perspective on the river’s long-term contamination. The Seine basin is inhabited by circa 17 million people and is impacted by intensive agricultural practices and industrial activities. These pressures have gradually affected its hydrological, chemical and ecological functioning, leading to a maximum chemical degradation between the 1960s and the 1990s. Over the last three decades, while major water-quality improvements have been observed, new issues (e.g. endocrine disruptors, microplastics) have also emerged. The state of the Seine River network, from the headwaters to estuary, is increasingly controlled by the balance between pressures and social responses. This socio-ecosystem provides a unique example of the functioning of a territory under heavy anthropogenic pressure during the Anthropocene era. The achievements made were possible due to the long-term PIREN Seine research program, established in 1989 and today part of the French socio-ecological research network “Zones Ateliers”, itself part of the international Long-term Socio-economic and Ecological Research Network (LTSER). Written by experts in the field, the book provides an introduction to the water budget and the territorial metabolism of the Seine basin, and studies the trajectories and impact of various pollutants in the Seine River. It offers insights into the ecological functioning, the integration of agricultural practices, the analysis of aquatic organic matter, and the evolution of fish assemblages in the Seine basin, and also presents research perspectives and approaches to improve the water quality of the Seine River. Given its scope, it will appeal to environmental managers, scientists and policymakers interested in the long-term contamination of the Seine River.
Download or read book Acid Waters in Wales written by R.W. Edwards and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together research into the process of stream acidification and its impact on Welsh surface waters, carried out over the past decade or so. It is perhaps surprising that not until the 1980's was clear evidence of stream acidification assembled. In Wales, concerns over pollution had focused water quality sampling principally on the areas of traditional heavy industry and large urban popula tions served by inadequate sewerage systems and sewage disposal arrange ments. Mistakenly, it had been assumed that, with its prevailing westerly winds, Wales would receive precipitation substantially unpolluted by the industrial and urban emissions from Britain and mainland Europe. Assurance of the high quality of Welsh upland streams, the traditional nursery ground of salmonids, was eroded particularly by studies in the vicinity of Llyn Brianne reservoir in the catchment of the River Tywi of Central Wales. These demonstrated a clear correspondence between the biological quality and fisheries of streams in the catchment and aspects of stream chemistry, par ticularly pH, aluminium and calcium on the one hand, and catchment land use on the other. It is salutary to record that the first signals were of an inexplicable failure of the runs of migratory salmonids into the upper catchment, occupied by the Llyn Brianne reservoir and its influent streams, and the failure to restore the fishery by re-stocking with eggs and fry. Only then did the significance of the recent decline in some other upland lake and reservoir fisheries in Wales become apparent.
Download or read book River Channel Restoration written by Andrew Brookes and published by . This book was released on 1996 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: River Channel Restoration summarises the current state of the art for river channel, floodplain and catchment restoration, and provides practical guiding principles for river managers. Fundamental principles are illustrated with case studies and experiences in a wide range of settings, principally Northern Europe and North America. An objective is to guide river managers away from trial and error approaches to appraisal and design. A multi-functional approach to restoration projects is needed, encompassing disciplines such as hydrology, hydraulics, geomorphology, water quality, ecology and landscape. Although concentrating on abiotic factors, this book will be of considerable interest to all disciplines with an interest in restoration. Contributors include university scientists, researchers, and practitioners from regulatory and consultancy organisations.

Download or read book The Wet Grassland Guide written by Phil Benstead and published by A & C Black. This book was released on 1997 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the UK there are some 1.5 million hectars of low-lying land, much of which has the potential to be wet grassland. Most has been drained and improved for agriculture - only 109,500 hectares support breeding waders. There are 32 RDB/candidate RDB species of birds which depend or partly depend on lowland wet grassland. In addition, some 500 of the 1500 British vascular plant species and large numbers of invertibrate may be found in this habitat.
