This ground-breaking collection of essays examines the scope and consequences of digital vigilantism – a phenomenon emerging on a global scale, which sees digital audiences using social platforms to shape social and political life. Longstanding forms of moral scrutiny and justice seeking are disseminated through our contemporary media landscape, and researchers are increasingly recognising the significance of societal impacts effected by digital media.The authors engage with a range of cross-disciplinary perspectives in order to explore the actions of a vigilant digital audience – denunciation, shaming, doxing – and to consider the role of the press and other public figures in supporting or contesting these activities. In turn, the volume illuminates several tensions underlying these justice seeking activities – from their capacity to reproduce categorical forms of discrimination, to the diverse motivations of the wider audiences who participate in vigilant denunciations.This timely volume presents thoughtful case studies drawn both from high-profile Anglo-American contexts, and from developments in regions that have received less coverage in English-language scholarship. It is distinctive in its focus on the contested boundary between policing and entertainment, and on the various contexts in which the desire to seek retribution converges with the desire to consume entertainment.Introducing Vigilant Audiences will be of great value to researchers and students of sociology, politics, criminology, critical security studies, and media and communication. It will be of further interest to those who wish to understand recent cases of citizen-led justice seeking in their global context.

Although the benefits of using grafted transplants are now fully recognized worldwide, the need to enlighten the scientific basis of rootstock-scion interactions under variable environmental pressures remains vital for extracting grafting-mediated crop improvement. This has prompted the COST (European Cooperation in Science and Technology) Action FA1204 entitled 'Vegetable grafting to improve yield and fruit quality under biotic and abiotic stress conditions' aimed at systematizing research findings. The COST action allowed the development of a multidisciplinary network of partners targeting the root system and employing rootstock breeding to unravel the mechanisms behind rootstock-mediated crop improvement: the enhancement of productivity and fruit quality, and the sustainability of vegetable crops under multiple and combined stresses. The current book is the major output of the COST Action and contains nine chapters drawing on the 2012-16 activities of four Working Groups (WGs) dealing with 'Genetic resources and rootstock breeding' (WG1), 'Rootstock-scion interactions and graft compatibility' (WG2), 'Rootstock-mediated resistance to biotic and abiotic stresses' (WG3) and 'Rootstock-mediated improvement of fruit quality' (WG4). While recent advances of scientific knowledge constitute the core of this COST book, valuable practical information is also provided on rootstock-scion combinations, on applicable grafting methods, on the establishment of grafted transplants and on recommendations for the use of grafted plants as an effective tool for sustainable vegetable production. This book is compiled as a collection of scientific information and as a practical tool aimed at both the people involved in the commercial production and cultivation of grafted plants, as well as researchers interested in an understanding of the science and technology behind a grafted plant.

s book is a detailed real account of all the key phases of the land tenure reform (LTR) programme in Rwanda and the critical factors that defined the outcomes and requirements for sustaining the process. In addition, the book provides an account of the impact of the programme, its challenges and lessons learned. Beyond LTR, this book also provides insights into emerging issues post-land tenure reform and what efforts are being undertaken to ensure sustainable land administration and land governance. The book draws on various types of secondary data, including relevant laws, policies, operational manuals and published studies, as well as consultants' reports. It also uses primary data comprising mainly interviews with policy makers, land professionals, academics, Civil Society Organisations (CSOs), donor organizations and the general public. This book is in four parts, with nine chapters. Part 1 provides the relevant context of the book and contains two chapters (chapters 1 and 2). Chapter 1 is the introduction and explains why land is so important; it discusses some of the issues land resources currently face, especially, in developing countries and why it should be managed and governed properly; it outlines why there is an urgent need for an improved land governance and land administration system or land tenure reform where this is not taking place, and it provides a summary of the importance of documenting Rwanda's LTR programme and explains why this book is timely and different from existing literature on land tenure reform. In chapter 2, the historical context of land tenure systems in Africa is summarized. Part 2 deals with the preparatory work that was carried out for land tenure reform and has one chapter (chapter 3). The chapter describes the key exercises that were undertaken as part of preparing the ground for the land tenure reform programme. Part 3 concentrates on implementation of the LTR programme and contains four chapters (chapters 4 to 7). Chapter 4 focuses on how the policy and regulatory frameworks were established which supported the LTR programme. Chapter 5 details the institutional framework that was developed to guide the LTR programme implementation, defining each institution's mandate and how they interacted with each other as well as how the capacity of these institutions was built to apportion responsibilities accordingly. Chapter 6 explains the whole process of rolling out the land tenure regularization process countrywide and the key steps that were involved, as well as the implementation process. In chapter 7, the key ingredients required to ensure that what has been achieved by the LTR would be properly maintained are assessed. The last part of the book (Part 4) assesses the impact of the LTR programme by discussing the socioeconomic benefits in chapter 8 where testimonies from various stakeholders and LTR beneficiaries are also presented. Chapter 9 concludes the book and a set of key success factors and lessons are also outlined for other countries wishing to follow a similar route as Rwanda in terms of land tenure reform.

This review provides an overview of all documented releases of exotic (non-European) invertebrate biological control agents (IBCAs) into the environment in Europe and summarizes key information on the target species as well as on the biological control agent released. It is an update of A Review of Biological Control in Western and Southern Europe edited by Greathead (1976) and covers the period from 1897, when the beetle Rodolia cardinalis was introduced into Portugal against the invasive cottony cushion scale, Icerya purchasi, until the end of 2009. This review is based largely on the BIOCAT database (Greathead and Greathead 1992), which contains records of the introduction of insect natural enemies, namely parasitoids and predators, for the control of insect pests worldwide. This review may not provide the complete list of BC agents introduced into Europe. Nevertheless, the report includes a vast majority of the introductions, and hence provides a representative picture of the history of releases of exotic BC agents into the environment in Europe.

This book reports on long-term comparative organic farming systems' research trials carried out over the last 5 years in the Southern Cape of South Africa, as well as research into the successes and failures of the organic sector and the technical tools required for sustainable development in South Africa, Zambia, Uganda and Tanzania. It includes 24 chapters organized into 4 parts. Part 1 (Chapters 1-6) discusses the historical development of organic farming systems, examines the global issues which confront us, and develops some concepts showing a progression in small-scale farmer development and how this can be supported with appropriate training and policy. The difference between national food self-sufficiency and household food security is examined, and the organic sector is introduced. Part 2 (Chapters 7-14) deals with capacity building and climate change. Holistic systems, inclusive participatory approaches, institution building and experiential learning are examined. Organic food production, farmer training, value chains, impact of drought on food prices and food availability, and urban water and energy use efficiency are described. Part 3 (Chapters 15-22) presents evidence on how to support organic farmers. It starts with 2 case studies on the well-developed organic sector in Uganda and the developing one in Zambia. The following chapters discuss soil carbon determination, comparison of organic and conventional farming systems, pest and disease control (e.g., chemical, holistic and biological control), soil fumigation, soil microbiology in organic and conventional systems, soil fertility changes and crop yield. Part 4 (Chapters 23-24) makes strategic suggestions about how to upscale organic farming and organic food systems in Southern Africa. This book is a vital resource for all stakeholders in organic agriculture.

This book is a contribution to the debate and knowledge for the rebalancing of farming and food using legumes. The main aim is to help people who are involved in developing cropping systems: the decision makers of today and today's students who are the decision makers of tomorrow. It is aimed at all relevant decision makers: farmers, professionals who support innovation in farming, and the policy community in its widest sense. It contains 13 chapters describing various aspects of the use of legumes (including grain and feed legumes) in European cropping systems. Each chapter provides deep insight into the relevant literature to support understanding rather than a comprehensive academic review. The aim is to empower the reader with insights and understanding of the underlying processes that influence cropping system development.

Despite the significant impacts of alien plant species (IAS), there has not been a concerted effort to tackle the problem across the region. This can mainly be ascribed to a lack of policy, little awareness and limited capacity at a national and regional level. The UN Environment-Global Environment Facility project, 'Removing Barriers to Invasive Species Management in Production and Protection Forests in SE Asia', which was active in Cambodia, Indonesia, the Philippines and Vietnam, identified these barriers and produced this Guide which will go a long way to creating awareness about invasive plants, their impacts and how best to manage them. This Guide will serve as an invaluable aid in the identification, mapping, monitoring, and management of IAS that are already present in ASEAN member states, or which may become problematic in the future, due to increased trade and travel, economic development and climate change. It is hoped that this Guide would trigger similar efforts in other countries in Southeast Asia as the region moves toward socio-economic integration.

The impetus for the development of this Field Guide came about as a result of pleas from the community around the village of Doldol, Laikipia County, to initiate a control programme for Australian prickly pear [Opuntia stricta (Haw.) Haw.; Fabaceae], an invasive plant which was having a dramatic impact on livelihoods. However, a number of other exotic plants, which were less widespread, but had the potential of becoming invasive, were not seen as a potential problem. In order to avoid a similar situation from arising in the future, the community expressed a need for a Field Guide, which would include descriptions of naturalized and invasive species already present in, and those that were most likely to invade Laikipia County and, information on how best to manage them. An additional impetus was to contribute to the four main objectives of the National Strategy and Action Plan for the Management of Invasive Species in Kenya's Protected Areas. The Field Guide contributes in some or other way to all of these objectives which are to (i) Enhance awareness of invasive species to relevant actors; (ii) Prevent new invasions, manage established invasions and rehabilitate degraded habitats; (iii) Enhance research, monitoring and information management on invasive species; and (iv) Enhance capacity, resource mobilization and coordination. Extensive surveys revealed the presence of a number of introduced plant species which had escaped cultivation and established populations in the 'wild' to the detriment of natural resources and the people that depend on them. Introduced succulents, especially those in the genus Opuntia (Cactaceae), were found to be the most widespread and abundant invasive species in the semi-arid regions in the north and east of Laikipia County. Other succulents, those in the genus Bryophyllum (Crassulaceae), were also found to have escaped cultivation and were locally abundant. In the higher rainfall areas to the west and southwest, introduced trees such as black wattle (Acacia mearnsii De Wild.; Fabaceae) and Australian blackwood (Acacia melanoxylon R. Br.; Fabaceae) and the shrubs/climbers, Mauritius thorn [Caesalpinia decapetala (Roth) Alston; Fabaceae] and yellow cestrum (Cestrum aurantiacum Lindl.; Solanaceae), were invasive. Introduced plants, which have the potential to become problematic in Laikipia, unless eradicated or controlled, have also been included in the Guide. This includes species such as famine weed (Parthenium hysterophorus L.; Asteraceae) and 'mathenge' [Prosopis juliflora (Sw.) DC.; Fabaceae], which are already abundant in areas adjoining the County.
