Download or read book Assessment of Sudden Death Syndrome by Utilizing Unmanned Aerial Vehicles and Multispectral Imagery written by Lindsey McKinzie and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusarium virguliforme is a soil-borne pathogen that is the causal agent of sudden death syndrome (SDS). This disease is one of the top contributors to major yield losses in soybean across the United States. Characteristic symptoms of the disease include interveinal chlorosis and/or necrosis of trifoliate leaves and defoliation. In some cases, the foliar symptoms may not be present, but yield loss still occurs. This disease is evaluated using an incidence rating, the percent of plants in the plot that are expressing symptoms, and a severity rating, using a one to nine scale based on varying levels of chlorosis, necrosis, and defoliation. Using remote sensing provides an alternate approach to identify and evaluate plant diseases. It provides a non-destructive method to assess the severity of foliar symptoms and their distribution across production fields. SDS was chosen as the disease to use for this system due to the unique disease symptomology and yield loss. In 2019 and 2020, SDS trials were established in a production field location that has a history of SDS in Valmeyer, IL. This seed treatment study had different chemicals with varying levels of efficacy against SDS. Disease ratings were collected at the first sign of symptoms, and aerial imagery was collected on the same day. There were multiple dates across both years when this data was collected. ArcGIS was used to analyze the multispectral imagery and do a plot by plot analysis for each of the plots. A regression analysis was performed to test the relationship between the foliar disease ratings and the plot data collected from the multispectral imagery. Multiple vegetation indices were tested, and the results showed that overall, in 2019, GNDVI had the strongest relationship with foliar ratings. In 2020, NDRE had the strongest overall relationship with foliar ratings. The relationship between NDVI and the ratings was the most consistent at the last rating of the season.
Download or read book Remote Sensing Applications for Agriculture and Crop Modelling written by Piero Toscano and published by MDPI. This book was released on 2020-02-13 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop models and remote sensing techniques have been combined and applied in agriculture and crop estimation on local and regional scales, or worldwide, based on the simultaneous development of crop models and remote sensing. The literature shows that many new remote sensing sensors and valuable methods have been developed for the retrieval of canopy state variables and soil properties from remote sensing data for assimilating the retrieved variables into crop models. At the same time, remote sensing has been used in a staggering number of applications for agriculture. This book sets the context for remote sensing and modelling for agricultural systems as a mean to minimize the environmental impact, while increasing production and productivity. The eighteen papers published in this Special Issue, although not representative of all the work carried out in the field of Remote Sensing for agriculture and crop modeling, provide insight into the diversity and the complexity of developments of RS applications in agriculture. Five thematic focuses have emerged from the published papers: yield estimation, land cover mapping, soil nutrient balance, time-specific management zone delineation and the use of UAV as agricultural aerial sprayers. All contributions exploited the use of remote sensing data from different platforms (UAV, Sentinel, Landsat, QuickBird, CBERS, MODIS, WorldView), their assimilation into crop models (DSSAT, AQUACROP, EPIC, DELPHI) or on the synergy of Remote Sensing and modeling, applied to cardamom, wheat, tomato, sorghum, rice, sugarcane and olive. The intended audience is researchers and postgraduate students, as well as those outside academia in policy and practice.

Download or read book NATO s Air War for Kosovo written by Benjamin S. Lambeth and published by Rand Corporation. This book was released on 2001-11-16 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a thorough appraisal of Operation Allied Force, NATO's 78-day air war to compel the president of Yugoslavia, Slobodan Milosevic, to end his campaign of ethnic cleansing in Kosovo. The author sheds light both on the operation's strengths and on its most salient weaknesses. He outlines the key highlights of the air war and examines the various factors that interacted to induce Milosevic to capitulate when he did. He then explores air power's most critical accomplishments in Operation Allied Force as well as the problems that hindered the operation both in its planning and in its execution. Finally, he assesses Operation Allied Force from a political and strategic perspective, calling attention to those issues that are likely to have the greatest bearing on future military policymaking. The book concludes that the air war, although by no means the only factor responsible for the allies' victory, certainly set the stage for Milosevic's surrender by making it clear that he had little to gain by holding out. It concludes that in the end, Operation Allied Force's most noteworthy distinction may lie in the fact that the allies prevailed despite the myriad impediments they faced.

Download or read book The impact of disasters and crises on agriculture and food security 2021 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-03-17 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: On top of a decade of exacerbated disaster loss, exceptional global heat, retreating ice and rising sea levels, humanity and our food security face a range of new and unprecedented hazards, such as megafires, extreme weather events, desert locust swarms of magnitudes previously unseen, and the COVID-19 pandemic. Agriculture underpins the livelihoods of over 2.5 billion people – most of them in low-income developing countries – and remains a key driver of development. At no other point in history has agriculture been faced with such an array of familiar and unfamiliar risks, interacting in a hyperconnected world and a precipitously changing landscape. And agriculture continues to absorb a disproportionate share of the damage and loss wrought by disasters. Their growing frequency and intensity, along with the systemic nature of risk, are upending people’s lives, devastating livelihoods, and jeopardizing our entire food system. This report makes a powerful case for investing in resilience and disaster risk reduction – especially data gathering and analysis for evidence informed action – to ensure agriculture’s crucial role in achieving the future we want.

Download or read book Using Science to Improve the BLM Wild Horse and Burro Program written by National Research Council and published by National Academies Press. This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.
Download or read book Whither Space Power written by Simon P. Worden and published by . This book was released on 2005-01-01 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of space power pervades almost every sphere and level of human existence, from politics to military affairs to commercial activities to cultural mind-sets. Yet there is little to be found today in the way of coherent space power doctrine and strategy, particularly in national security circles. To what extent do our national interests rely on space? How shall we defend our interests in space and how shall we deny our adversaries the benefits of space power in time of conflict? How can we control and exploit the space environment? How can we effectively wield space power against the full spectrum of threats -- from the lone terrorist to global peer competitors? What should be our long-range strategy and objectives if our goal is to achieve and maintain long-term space superiority? The purpose of this paper is two fold: first, to illuminate the historical and ever-increasing importance of space in modern society; and second, to prescribe, in view of this importance, the foundations of a strategy for achieving lasting space superiority and ensuring national and world security.

Download or read book Why Forests Why Now written by Frances Seymour and published by Brookings Institution Press. This book was released on 2016-12-27 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests are an undervalued asset in meeting the greatest global challenges of our time—averting climate change and promoting development. Despite their importance, tropical forests and their ecosystems are being destroyed at a high and even increasing rate in most forest-rich countries. The good news is that the science, economics, and politics are aligned to support a major international effort over the next five years to reverse tropical deforestation. Why Forests? Why Now? synthesizes the latest evidence on the importance of tropical forests in a way that is accessible to anyone interested in climate change and development and to readers already familiar with the problem of deforestation. It makes the case to decisionmakers in rich countries that rewarding developing countries for protecting their forests is urgent, affordable, and achievable.
Download or read book Keeping Watch written by A. Walter Dorn and published by UN. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge is power. In the hands of UN peacekeepers, it can be a power for peace. Lacking knowledge, peacekeepers often find themselves powerless in the field, unable to protect themselves and others. The United Nations owes it to the world and to its peacekeepers to utilize all available tools to make its monitoring and surveillance work more effective. "Keeping Watch" explains how technologies can increase the range, effectiveness, and accuracy of UN observation. Satellites, aircraft, and ground sensors enable wider coverage of many areas, over longer periods of time, while decreasing intrusiveness. These devices can transmit and record imagery for wider dissemination and further analysis, and as evidence in human rights cases and tribunals. They also allow observation at a safe distance from dangerous areas, especially in advance of UN patrols, humanitarian convoys, or robust forces. While sensor technologies have been increasing exponentially in performance while decreasing rapidly in price, however, the United Nations continues to use technologies from the 1980s. This book identifies potential problems and pitfalls with modern technologies and the challenges to incorporate them into the UN system. The few cases of technologies effectively harnessed in the field are examined, and creative recommendations are offered to overcome the institutional inertia and widespread misunderstandings about how technology can complement human initiative in the quest for peace in war-torn lands. ""Walter Dorn is one of the most thoughtful and knowledgeable analysts of peacekeeping and security policy, and this book makes an important contribution to a field that needs far more public discussion.""--The Hon. Bob Rae, MP for Toronto Centre and Liberal Foreign Affairs critic
Download or read book Deep Maneuver written by Jack D Kern Editor and published by Createspace Independent Publishing Platform. This book was released on 2018-10-12 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 5, Deep Maneuver: Historical Case Studies of Maneuver in Large-Scale Combat Operations, presents eleven case studies from World War II through Operation Iraqi Freedom focusing on deep maneuver in terms of time, space and purpose. Deep operations require boldness and audacity, and yet carry an element of risk of overextension - especially in light of the independent factors of geography and weather that are ever-present. As a result, the case studies address not only successes, but also failure and shortfalls that result when conducting deep operations. The final two chapters address these considerations for future Deep Maneuver.
