    A Local Approach: Homeland Security Officers

    Get PDF
    It has become apparent that true preparedness for a catastrophic event requires a strong local component. However, the patchwork of full and part time operators in a range of disciplines preparing for a variety of responsibilities creates the risk of an inexact or inefficient response. As a result, this document will support the idea that in order to improve the level of preparedness of municipalities, one full time police officer should be assigned to the newly created position of Homeland Security Officer (HSO), and be tasked with all manner of responsibilities for the most effective example of homeland security. This Project will introduce the Homeland Security Officer position; its responsibilities and justifications. Various chapters will examine the position through the prisms of Management, Public Sector Policy Analysis, Multi-disciplinary Collaboration, and Public Health Emergencies. Two Strategic Plans are included: one for the Police Department of Pleasantville, New York, and a second for Terrorist Threats associated with living and / or working as an American in Germany. Specific threats to Pleasantville are also considered. A Threat Assessment of an attack similar to the one on Mumbai in 2008; and a Model Based Vulnerability Analysis (MBVA) of the Critical Infrastructure of the Drinking Water supply. Finally, there are some larger issues considered: Constitutional Issues in Homeland Security and International Human Rights Concerns for America

    Forest and Rangeland Soils of the United States Under Changing Conditions

    This open access book synthesizes leading-edge science and management information about forest and rangeland soils of the United States. It offers ways to better understand changing conditions and their impacts on soils, and explores directions that positively affect the future of forest and rangeland soil health. This book outlines soil processes and identifies the research needed to manage forest and rangeland soils in the United States. Chapters give an overview of the state of forest and rangeland soils research in the Nation, including multi-decadal programs (chapter 1), then summarizes various human-caused and natural impacts and their effects on soil carbon, hydrology, biogeochemistry, and biological diversity (chapters 2–5). Other chapters look at the effects of changing conditions on forest soils in wetland and urban settings (chapters 6–7). Impacts include: climate change, severe wildfires, invasive species, pests and diseases, pollution, and land use change. Chapter 8 considers approaches to maintaining or regaining forest and rangeland soil health in the face of these varied impacts. Mapping, monitoring, and data sharing are discussed in chapter 9 as ways to leverage scientific and human resources to address soil health at scales from the landscape to the individual parcel (monitoring networks, data sharing Web sites, and educational soils-centered programs are tabulated in appendix B). Chapter 10 highlights opportunities for deepening our understanding of soils and for sustaining long-term ecosystem health and appendix C summarizes research needs. Nine regional summaries (appendix A) offer a more detailed look at forest and rangeland soils in the United States and its Affiliates

    World Water Development Report 4: Managing Water Under Uncertainty and Risk

    Get PDF
    Building on the comprehensive approach taken in World Water Development Reports (WWDRs) 1 and 2, and the holistic view taken in WWDR3, this fourth edition gives an account of the critical issues facing water's challenge areas and different regions and incorporates a deeper analysis of the external forces (i.e. drivers) linked to water. In doing so, the WWDR4 seeks to inform readers and raise awareness of the new threats arising from accelerated change and of the interconnected forces that create uncertainty and risk - ultimately emphasizing that these forces can be managed effectively and can even generate vital opportunities and benefits through innovative approaches to allocation, use and management of water

    Healthy communities rely on well-functioning ecosystems. They provide clean air, fresh water, medicines and food security. They also limit disease and stabilize the climate. But biodiversity loss is happening at unprecedented rates, impacting human health worldwide.The report, Connecting Global Priorities: Biodiversity and Human Health, focuses on the complex and multi-faceted connections between biodiversity and human health, and how the loss of biodiversity and corresponding ecosystem services may negatively influence health. One of the first integrative reviews of its kind, the report brings together knowledge from several scientific disciplines, including public health, conservation, agriculture, epidemiology and development. The book is a joint publication of the Convention on Biological Diversity and World Health Organization. Danny Hunter, Senior Scientist, Bioversity International is one of the Lead Coordinating Authors of the book and co-lead author on two chapters:Chapter 5: Agricultural biodiversity and food security Chapter 6: Biodiversity and nutritio

    World Water Development Report 3: Water in a Changing World

    Get PDF
    With the release of this third edition of The United Nations World Water Development Report, it is clear that urgent action is needed if we are to avoid a global water crisis. Despite the vital importance of water to all aspects of human life, the sector has been plagued by a chronic lack of political support, poor governance and underinvestment. As a result, hundreds of millions of people around the world remain trapped in poverty and ill health and exposed to the risks of water-related disasters, environmental degradation and even political instability and conflict. Population growth, increasing consumption and climate change are among the factors that threaten to exacerbate these problems, with grave implications for human security and development.The current Report provides a comprehensive analysis of the state of the world's freshwater resources. It also, for the first time, shows how changes in water demand and supply are affected by and affect other global dynamics. It represents a considerable collaborative achievement for the 26 UN agencies that make up UN-Water and are engaged in the World Water Assessment Programme (WWAP), which leads the monitoring and evaluation behind the Report. UNESCO is very proud to have played a pivotal role in the launch of this flagship programme and to continue to support its work by housing the WWAP Secretariat. I am confident that this third volume will prove crucial as a working tool for policy-makers and other stakeholders, providing solid evidence from which to develop an effective and sustainable approach to water issues

    Rural food security in Mutare District, Zimbabwe, 1947-2010

    Get PDF
    By taking Mutare District as its lens to explore the dynamics of rural food security in Zimbabwe, this thesis assesses the role of the state in tackling hunger among its rural populations. It examines the impact of colonial and post-colonial food policy on efforts to combat food insecurity. The thesis explores the uneasy options pursued by rural communities in response to droughts and other threats of hunger. It identifies and ranks crop failure as the chief culprit to the district’s efforts towards food security. The thesis illustrates the contestations between the state and its rural people over which sustainable approaches to adopt in order to end hunger and how such debates continually shaped policy. It grapples with questions about the various understandings of food security advanced by scholars within the rural African context. It demonstrates, for instance, that the post-colonial state inherited an erstwhile crop production structure which shunned food crops in favour of cash crops. There was obvious bias against local preferences for a robust, home-grown food regime which did not put rural livelihoods at risk of starvation. The thesis also argues that food can be used as an instrument of war as evidenced during the liberation struggle when the vast majority of people residing in rural areas, particularly women and children, were pushed to the edges of survival. In addition, the thesis demonstrates that the infamous Marange diamonds turned out to be a curse rather than a blessing due to the state’s lack of transparency in the beneficiation chain. It concludes by a detailed examination of the political economy of food aid, demonstrating why donors have not succeeded for long to combat hunger in the district. In light of this background, the thesis provides a more nuanced analysis of the whole question of rural food security using archival material, newspapers, government and civil society reports, interviews and field observation. The thesis benefits from the use of a multi-pronged theoretical framework to capture the disparate themes that form the bedrock of this study
