Volcanic eruptions are complex and inherently uncertain, making the management of a potentially explosive eruption on a small island with limited resources extremely difficult. This volume presents scientific findings from the 2020–21 eruption of La Soufrière Volcano, on the island of St Vincent in the Eastern Caribbean. This involved three months of effusive activity that escalated rapidly to 13 days of explosive activity, beginning with an intense two days of near-continuous ash venting and explosions. The book contains an introduction and 17 papers, split into two parts: the first presents geological and volcanological advances, whereas the second documents and analyses the impacts of the eruption and the challenges presented for the management of the volcanic crisis. This volume represents both significant contributions to the knowledge of the Soufrière eruptive system and important insights into the ways and means by which volcanic eruptions of this type impact on populations at risk. It also provides detailed insights into the most effective communication processes through this type of crisis.

This volume is unique because of its focus on small states. There are many studies on civil society and social movements, but none that specifically deal with this category of countries. As is well known, small states have particular characteristics, including a limited ability to reap the benefits of economies of scale, a high degree of exposure to forces outside their control, and the proximity of politicians to the voters, often leading to clientelistic relationships and patronage networks. The small island developing states have the additional problem of high environmental vulnerability, with some also dealing with disproportionate ecological footprints. These factors have a bearing on the organization and performance of civil society organizations and social movements, as explained in several chapters of this book. The volume is organized in three parts, dealing with aspects of civil society and social moments in small states in the political, social and environmental spheres, respectively. Various definitions of civil society are proposed in the chapters, but most authors associate the term with organized groups, operating in the interest of citizens, independently of government and commercial business, including various forms of non-governmental organizations (NGOs). Civil society also encompasses social movements, which are considered to be loosely organized collective campaigns in pursuit of social goals. These two terms are sometimes used interchangeably; however, some authors argue that social movements tend to engage in ‘contentious politics’ including protests, while NGOs engage through more organized and institutional routes.

An explosive volcanic eruption that began on April 9 is hitting St. Vincent and the Grenadines hard, creating an urgent balance of payments need and a humanitarian crisis as the country continues to deal with the fallout from the global pandemic. The economy is estimated to have contracted in 2020 by 3.8 percent as tourism activity fell 70 percent. Before the eruption, economic growth was expected to be flat in 2021, as the global pandemic continued, and tourism remained depressed. While there is considerable uncertainty about the evolution of the eruption, staff estimate the infrastructure damage to exceed 20 percent of GDP and for the economy to contract by 6.1 percent in 2021 with agriculture and related sectors severely affected.

Barbados has made good progress in implementing its Economic Recovery and Transformation (BERT) plan to restore fiscal and debt sustainability, rebuild reserves, and increase growth. International reserves have increased to US$1.3 billion at end-March 2021, supported by IFI loans. This, and a successful 2018-19 public debt restructuring, have helped rebuild confidence in the country’s macroeconomic framework. However, a virtual standstill in the tourism sector during the pandemic took a significant toll in 2020, with the economy contracting by 18 percent. While Barbados was successful in containing the outbreak during 2020, a surge in COVID-19 cases in early 2021 resulted in the country’s second national lockdown in February. Economic growth is projected at 3 percent for 2021 premised on a modest recovery of tourism in the second half of the year, but the outlook remains highly uncertain, and risks are elevated, also in light of the possible impact of recent volcanic activity in neighboring Saint Vincent.

This open access book summarizes the findings of the VUELCO project, a multi-disciplinary and cross-boundary research funded by the European Commission's 7th framework program. It comprises four broad topics: 1. The global significance of volcanic unrest 2. Geophysical and geochemical fingerprints of unrest and precursory activity 3. Magma dynamics leading to unrest phenomena 4. Bridging the gap between science and decision-making Volcanic unrest is a complex multi-hazard phenomenon. The fact that unrest may, or may not lead to an imminent eruption contributes significant uncertainty to short-term volcanic hazard and risk assessment. Although it is reasonable to assume that all eruptions are associated with precursory activity of some sort, the understanding of the causative links between subsurface processes, resulting unrest signals and imminent eruption is incomplete. When a volcano evolves from dormancy into a phase of unrest, important scientific, political and social questions need to be addressed. This book is aimed at graduate students, researchers of volcanic phenomena, professionals in volcanic hazard and risk assessment, observatory personnel, as well as emergency managers who wish to learn about the complex nature of volcanic unrest and how to utilize new findings to deal with unrest phenomena at scientific and emergency managing levels.

This book focuses on the highly touristed, but surprisingly under-researched Lesser Antilles region. After offering a brief overview of the region’s geologic and tectonic history, as well as its basic climatology, subsequent chapters then discuss each island’s (or island set’s) geomorphology and geology, and how the settlement history, tourism, and hazards have affected their individual landscapes. Written by regional experts and replete with up-to-date information, stunning color imagery, and beautiful cartography (maps), it is the only comprehensive, scientific evaluation of the Lesser Antilles, and serves as the region’s definitive reference resource. Accessible to non-experts and amateur explorers, the book includes in-depth discussions and reference sections for each island/island set. Usable as both a textbook and guidebook, it offers readers a straightforward yet detailed assessment of an interesting and intriguing – but often-overlooked and under-appreciated – locale.

This long-awaited book about non-pollen palynomorphs (NPPs) aims to cover gaps in our knowledge of these abundant but understudied palynological remains. NPPs, such as fungal spores, testate amoebae, dinoflagellate cysts, acritarchs and animal remains, are routinely recovered from palynological preparations of marine or terrestrial material, from Proterozoic to recent geological times. This book gives the reader a comprehensive overview of the different types of NPPs, with examples from diverse time periods and environments. It provides guidance on sample preparation to maximize the recovery of these NPPs, detailed information on their diversity and ecological affinity, clarification on the nomenclature and demonstrates their value as environmental indicators. This volume will become the reference guide for any student, academic or practitioner interested in everything else in their palynological preparations.
