        One Welfare Animal Health and Welfare, Food Security and Sustainability

        by Rebeca García Pinillos, Stella Maris Huertas Canén

        This thought-provoking book explores the link between animals, people and their social and physical environments in relation to livestock farming, food safety, food security and sustainability. Providing an overview of livestock farming and animal related food production systems in a one welfare context, One Welfare: Animal Health and Welfare, Food Security and Sustainability begins by considering the interconnections of animals, humans and their environment. It then expands into the food production system, and considers the integration of positive welfare, stress, use of welfare indicators and the economic perspective. Written by a team of international experts, it connects theory with best practice examples and case studies from both organizations and individuals that have successfully implemented a one welfare approach. Essential reading for academics and practitioners who work within farming, food systems and international development, this ground-breaking text is also an important read for veterinary and animal welfare professionals.

        Application Technology for Crop Protection

        by Edited by Graham A Matthews, E C Hislop

        Pesticides continue to be a major means of controlling pests and diseases of crops and have made a major contribution to increasing the world’s food production. Despite the problem of developing pest and disease resistance to certain pesticides, and public concern about their indiscriminate use and side-effects, they are likely to remain the basis of integrated pest management programmes. However, as this book seeks to demonstrate, there is scope to improve both the safety and efficiency of crop protection methods. The emphasis of the book is on methods of assessment and on application techniques to particular categories of crops. Written by leading authorities from Europe and North America, the book provides detailed reviews of relevant topics. It is essential reading for all researchers, advanced students and professionals concerned with crop protection, whether from the disciplines of entomology, plant pathology, weed science or agricultural engineering.

        Forage production and utilization technology

        by Yan Jingcai

        The combination of planting and breeding and the development of moderate scale breeding has been proved to be a good way to solve the problem of forage supply and improve the efficiency of herbivore breeding in mountainous and hilly areas. This book takes forage production and forage technology as the theme. On the basis of introducing the current situation of forage production and herbivore breeding, it is compiled in accordance with the clues of forage varieties suitable for planting in southern provinces and their production technology, forage processing and storage technology, and forage utilization technology. The book introduces more than 30 kinds of forage grass, and introduces the feeding technology of forage grass in cattle, sheep, geese and pigs.

        RNAi for Plant Improvement and Protection

        by Bruno Mezzetti, Jeremy Sweet, Lorenzo Burgos

        RNA interference (RNAi) has the potential to make major contributions towards sustainable crop production and protection with minimal environmental impacts compared to other technologies. RNAi is being developed and exploited both within plants (i.e. host-induced gene silencing, HIGS) and/or as topical applications (e.g. spray-induced gene silencing, SIGS) for targeting pest and pathogen genes and for manipulating endogenous gene expression in plants. Chapters by international experts review current knowledge on RNAi, methods for developing RNAi systems in GM plants and applications for crop improvement, crop production and crop protection. Chapters examine both endogenous systems in GM plants and exogenous systems where interfering RNAs are applied to target plants, pests and pathogens. The biosafety of these different systems is examined and methods for risk assessment for food, feed and environmental safety are discussed. Finally, aspects of the regulation of technologies exploiting RNAi and the socio-economic impacts of RNAi technologies are discussed.
