This book was released on 2019-12-13 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vessel traffic data based on the Automatic Identification System (AIS) is a big data source for nowcasting trade activity in real time. Using Malta as a benchmark, we develop indicators of trade and maritime activity based on AIS-based port calls. We test the quality of these indicators by comparing them with official statistics on trade and maritime statistics. If the challenges associated with port call data are overcome through appropriate filtering techniques, we show that these emerging “big data” on vessel traffic could allow statistical agencies to complement existing data sources on trade and introduce new statistics that are more timely (real time), offering an innovative way to measure trade activity. That, in turn, could facilitate faster detection of turning points in economic activity. The approach could be extended to create a real-time worldwide indicator of global trade activity.

This book was released on 2020-05-14 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maritime data from the Automatic Identification System (AIS) have emerged as a potential source for real time information on trade activity. However, no globally applicable end-to-end solution has been published to transform raw AIS messages into economically meaningful, policy-relevant indicators of international trade. Our paper proposes and tests a set of algorithms to fill this gap. We build indicators of world seaborne trade using raw data from the radio signals that the global vessel fleet emits for navigational safety purposes. We leverage different machine-learning techniques to identify port boundaries, construct port-to-port voyages, and estimate trade volumes at the world, bilateral and within-country levels. Our methodology achieves a good fit with official trade statistics for many countries and for the world in aggregate. We also show the usefulness of our approach for sectoral analyses of crude oil trade, and for event studies such as Hurricane Maria and the effect of measures taken to contain the spread of the novel coronavirus. Going forward, ongoing refinements of our algorithms, additional data on vessel characteristics, and country-specific knowledge should help improve the performance of our general approach for several country cases.
Download or read book Tuvalu written by International Monetary Fund. Asia and Pacific Dept and published by International Monetary Fund. This book was released on 2023-07-21 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2023 Article IV Consultation discusses that a successful vaccination strategy allowed Tuvalu to lift coronavirus disease (COVID) containment measures at the end of 2022, but the economic cost of the pandemic has been significant. Real gross domestic product growth was -4.3 percent in 2020, with at-the-border containment measures leading to delays in much-needed infrastructure projects. Growth is expected to accelerate as the lifting of COVID restrictions leads to the resumption of construction activity, shipping bottlenecks ease and the trade and hospitality sectors recover. Tuvalu is among the countries most vulnerable to the effects of climate change; its remote economy is dominated by the public sector; and its revenue base is narrow, with reliance on donor commitments further complicating fiscal planning. The economic setback due to the pandemic makes addressing these significant structural challenges more difficult. The report recommends promoting fiscal sustainability and building buffers by mobilizing revenues and rationalizing current expenditures.

Download or read book World Economic Outlook October 2023 written by International Monetary Fund. Research Dept. and published by International Monetary Fund. This book was released on 2023-10-10 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: The latest World Economic Outlook reports signs that policy tightening is starting to cool activity despite core inflation proving persistent. Risks are more balanced as banking sector stress has receded, but they remain tilted to the downside. Monetary policy should stay the course to bring inflation to target, while fiscal consolidation is needed to tackle soaring debts. Structural reforms are crucial to revive medium-term growth prospects amid constrained policy space.
Download or read book Building Statistical Capacity in Fragile and Conflict Affected States written by Ms. Stephanie C Medina Cas and published by International Monetary Fund. This book was released on 2022-02-25 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on internal data, this paper finds that the capacity development program of the IMF’s Statistics Department has prioritized technical assistance and training to fragile and conflict-affected states. These interventions have yielded only slightly weaker results in fragile states than in other states. However, capacity development is constantly needed to make up for the dissipation of progress resulting from insufficient resources that fragile and conflict-affected states allocate to the statistical function, inadequate inter-agency coordination, and the pervasive impact of shocks exogenous to the statistical system. Greater coordination with other capacity development providers and within the IMF can help partially overcome low absorptive capacity in fragile states. Statistical capacity development is more effective when it is tailored to countries’ level of fragility.

Download or read book Next Generation Earth System Prediction written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-22 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the nation's economic activities, security concerns, and stewardship of natural resources become increasingly complex and globally interrelated, they become ever more sensitive to adverse impacts from weather, climate, and other natural phenomena. For several decades, forecasts with lead times of a few days for weather and other environmental phenomena have yielded valuable information to improve decision-making across all sectors of society. Developing the capability to forecast environmental conditions and disruptive events several weeks and months in advance could dramatically increase the value and benefit of environmental predictions, saving lives, protecting property, increasing economic vitality, protecting the environment, and informing policy choices. Over the past decade, the ability to forecast weather and climate conditions on subseasonal to seasonal (S2S) timescales, i.e., two to fifty-two weeks in advance, has improved substantially. Although significant progress has been made, much work remains to make S2S predictions skillful enough, as well as optimally tailored and communicated, to enable widespread use. Next Generation Earth System Predictions presents a ten-year U.S. research agenda that increases the nation's S2S research and modeling capability, advances S2S forecasting, and aids in decision making at medium and extended lead times.

Download or read book Lightning written by Chandima Gomes and published by Springer Nature. This book was released on 2021-08-13 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the essential theoretical and practical aspects of lightning, lightning protection, safety and education. Additionally, several auxiliary topics that are required to understand the core themes are also included. The main objective of the contents is to enlighten the scientists, researchers, engineers and social activists (including policy makers) in developing countries regarding the key information related to lightning and thunderstorms. A majority of developing countries are in tropics where the lightning characteristics are somewhat different from those in temperate regions. The housing structures and power/communication networks, and human behavioural patterns(that depends on socio-economic parameters) in these countries are also different from those in the developed world. As the existing books on similar themes address only those scenarios in developed countries, this book serves a vast spectrum of readership in developing world who seek knowledge in the principles of lightning and a practical guidance on lightning protection and safety education.

Download or read book Climate Change Impacts and Adaptation for Transport Networks and Nodes written by United Nations Publications and published by . This book was released on 2020-04-14 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the analyses of several climate variables relevant to transport networks and nodes within the ECE region. Regional maps have been produced in Geographical Information System (GIS) format, showing the main transportation networks, which have been overlain by the spatial distribution of the climate change projections, thereby presenting an initial perspective of areas of potential risk which could warrant more in-depth assessment. The Group of Experts has also reviewed and presented country experiences in the form of case studies, demonstrating a range of efforts that have been undertaken to analyse climate change impacts on transport assets and operations. With its work, the Group of Experts wishes to raise awareness on the importance of considering climate change and extreme weather (for example, in planning, construction, maintenance and operations) and of strengthening the climate resilience of inland transport assets, networks and nodes. It also aims to stimulate the continuation of work to establish the necessary analytical basis to facilitate local or regional assessments, leading to the identification of specific transport assets at risk which may require adaptation efforts. The Group of Experts, within this report, also formulated a series of lessons learned which have served as a basis to recommend future action at national and international levels towards improved transportation system climate resilience.
