by Zeba Khan, Nicoleta Anca Sutan
Nanotechnology research and its application in agriculture has become a major focus in recent years. Nanoformulations offer the possibility to develop more efficient and less damaging agrochemicals in the environment. Smart delivery systems for nanosensors, molecules that can help to detect biotic or abiotic stresses before they can affect production, are being developed and applied. Nanotechnology also provides new techniques for genetic manipulation and plant breeding. The use of nanoformulations in agriculture is increasingly being used to enhance food values, reduce agricultural inputs, improve nutrient contents and create a longer shelf life for many products. Nanotechnology is also being applied to many aspects of food security, disease treatment, new tools for pathogen detection, effective delivery systems and packaging materials. It is hoped that all these applications will help meet the needs of a growing population, and help mitigate the effects of climate change and other ecological disturbances.

Humanities & Social SciencesSeptember 2023Negotiating relief and freedom
Responses to disaster in the British Caribbean, 1812-1907
by Oscar Webber
Negotiating relief and freedom is an investigation of short- and long-term responses to disaster in the British Caribbean colonies during the 'long' nineteenth century. It explores how colonial environmental degradation made their inhabitants both more vulnerable to and expanded the impact of natural phenomena such as hurricanes, earthquakes, and volcanic eruptions. It shows that British approaches to disaster 'relief' prioritised colonial control and 'fiscal prudence' ahead of the relief of the relief of suffering. In turn, that this pattern played out continuously in the long nineteenth century is a reminder that in the Caribbean the transition from slavery to waged labour was not a clean one. Times of crisis brought racial and social tensions to the fore and freedoms once granted, were often quickly curtailed.

Science & MathematicsMarch 2022Encyclopedia of Scale Insect Pests
by Takumasa Kondo, Gillian Watson
Scale insects feed on plant juices and can easily be transported to new countries on live plants. They sometimes become invasive pests, costing billions of dollars in damage to crops worldwide annually, and farmers try to control them with toxic pesticides, risking environmental damage. Fortunately, scale insects are highly susceptible to control by natural enemies so biological control is possible. They have unique genetic systems, unusual metamorphosis, a broad spectrum of essential symbionts, and some are sources of commercial products like red dyes, shellac and wax. There is, therefore, wide interest in these unusual, destructive, beneficial, and abundant insects. The Encyclopedia of Scale Insect Pests is the most comprehensive work on worldwide scale insect pests, providing detailed coverage of the most important species (230 species in 26 families, 36% of the species known). Advice is provided on collection, preservation, slide-mounting, vouchering, and labelling of specimens, fully illustrated with colour photographs, diagrams and drawings. Pest species are presented in two informal groups of families, the 'primitive' Archaeococcids followed by the more 'advanced' Neococcids, covered in phylogenetic order. Each family is illustrated and diagnosed based on features of live and slide-mounted specimens, with information on numbers of genera and species, main hosts, distribution, and biology. For the important pest species, coverage includes information on the morphology of live and slide-mounted specimens, common names, principal synonyms, geographical distribution, plant hosts, plant damage and economic impact, reproductive biology, dispersal, and management strategies including biological, cultural and chemical control, sterile insect techniques, regulatory control, early warning systems and field monitoring. An additional complete list of scale insect pests worldwide is provided, comprising 642 species in 28 scale insect families (about 8% of the 8396 species of living scales known), with information on plant hosts, geographical distribution and validation sources. Beneficial uses of scale insects as sources of red dyes, natural resins and waxes, as agents for invasive weed control. The importance of their honeydew to bees for making honey, and as a food source to other animals, are included. Academic researchers, students, entomologists, pest management officials in agribusiness or government including plant quarantine identifiers, extensionists, farmers, field scientists and ecologists will all benefit from this book.

Climate Change and Sustainable Agro-ecology in Global Drylands
by Adel El-Beltagy, Rattan Lal, Kauser Abdulla Malik
Drylands, a home for nearly 2.5 billion people, are highly vulnerable to anthropogenic climate change, and dryland area may expand to 50% of the Earth's surface by 2100. Climate change may aggravate the prevalence of undernutrition and malnutrition because of adverse effects on quantity and quality of food production in these regions. This book takes a holistic approach to sustainable management of drylands to make agriculture drought-resilient. Eminent scientists from around the world share their knowledge and experiences for adaptation and mitigation of the anthropogenic climate change through innovation in sustainable management of water, soil, crops, livestock, and fisheries. They anticipate that climate change will have major impacts on agro- ecosystems which requires continuous dynamic assessments, globally, regionally, and at the local level where the major action of adaptation would have to occur. The assessment will require international cooperation and national capacity-building. This book emphasizes approaches such as smart and precision agriculture, conservation agriculture, and new innovation and technology as tools for adaptation and mitigation. Several chapters are devoted to the human dimensions and policy considerations with emphasis on enhancing coping and adaptive capacity. This book addresses the picture after COP27, including loss and damage, governance and finance. This book: Examines sustainable management for drylands as a solution to environmental and food security issues. Uses a holistic approach to evaluate sustainable management of drylands. Explains how researchers are translating science into action for greening global drylands. This work will be valuable to students and researchers in agroecology, climate change science and dryland agriculture.

Animal husbandryNovember 2008Environmental Impacts of Pasture-based Farming
by Edited by Richard McDowell
Focusing on the different types of pastoral farming and their impact on the environment, Environmental Impacts of Pasture-based Farming takes a broad view of the subject, whose treatment in texts is often biased towards confined animal or grain based systems. The text is organised into two sections, the first addressing issues facing environmental quality, namely soil, water and air quality and socio-economic impacts. The second section offers commentary on how pastoral sectors influence environmental issues. With highly tuned farm productive systems comes the risk of environmental impacts, and the purpose of this text is to highlight the areas in which these risks are associated and how best to mitigate them. An approach is taken that highlights these problems, but also keeps in mind that mitigation may be too restrictive on the farming system and make farming impractical.
