While plastics are extremely useful materials for modern society, plastics production and waste generation continue to increase with worsening environmental impacts despite international, national and local policy responses, as well as industry commitments. The first of two reports, this Outlook intends to inform and support policy efforts to combat plastic leakage.
This economic report on Tonga is the result of a joint project of the Asian Development Bank (ADB) and the Australian Agency for International Development. It is part of ADB's Pacific Islands Economic Report series, which aims to assist governments in formulating policy by analyzing a country's economic and socioeconomic situation, key issues, and development prospects. The report provides a longitudinal study of the Tonga economy covering the last 2 decades.
Solid waste management affects every person in the world. By 2050, the world is expected to increase waste generation by 70 percent, from 2.01 billion tonnes of waste in 2016 to 3.40 billion tonnes of waste annually. Individuals and governments make decisions about consumption and waste management that affect the daily health, productivity, and cleanliness of communities. Poorly managed waste is contaminating the world’s oceans, clogging drains and causing flooding, transmitting diseases, increasing respiratory problems, harming animals that consume waste unknowingly, and affecting economic development. Unmanaged and improperly managed waste from decades of economic growth requires urgent action at all levels of society. What a Waste 2.0: A Global Snapshot of Solid Waste Management to 2050 aggregates extensive solid aste data at the national and urban levels. It estimates and projects waste generation to 2030 and 2050. Beyond the core data metrics from waste generation to disposal, the report provides information on waste management costs, revenues, and tariffs; special wastes; regulations; public communication; administrative and operational models; and the informal sector. Solid waste management accounts for approximately 20 percent of municipal budgets in low-income countries and 10 percent of municipal budgets in middle-income countries, on average. Waste management is often under the jurisdiction of local authorities facing competing priorities and limited resources and capacities in planning, contract management, and operational monitoring. These factors make sustainable waste management a complicated proposition; most low- and middle-income countries, and their respective cities, are struggling to address these challenges. Waste management data are critical to creating policy and planning for local contexts. Understanding how much waste is generated—especially with rapid urbanization and population growth—as well as the types of waste generated helps local governments to select appropriate management methods and plan for future demand. It allows governments to design a system with a suitable number of vehicles, establish efficient routes, set targets for diversion of waste, track progress, and adapt as consumption patterns change. With accurate data, governments can realistically allocate resources, assess relevant technologies, and consider strategic partners for service provision, such as the private sector or nongovernmental organizations. What a Waste 2.0: A Global Snapshot of Solid Waste Management to 2050 provides the most up-to-date information available to empower citizens and governments around the world to effectively address the pressing global crisis of waste.

The uptake of ecosystem-based approaches for disaster risk reduction (DRR) is slow, however, despite some success stories. There are multiple reasons for this reluctance: ecosystem management is rarely considered as part of the portfolio of DRR solutions because the environmental and disaster management communities typically work independently from each other; its contribution to DRR is highly undervalued compared to engineered solutions and therefore not given appropriate budget allocations; and there are poor interactions between policymakers and researchers, leading to unclear and sometimes contradictory scientific information on the role of ecosystems for DRR. The aim of this book is to provide an overview of knowledge and practice in this multidisciplinary field of ecosystems management and DRR. The contributors, professionals from the science and disaster management communities around the world, represent state-of-the-art knowledge, practices, and perspectives on the topic.

Tonga is one of the world’s most exposed countries to climate change and natural disasters. It suffered the highest loss from natural disasters in the world (as a ratio to GDP) in 2018 and is among the top five over the last decade (Table 1). Climate change will make this worse. Cyclones will become more intense, with more damage from wind and sea surges. Rising sea levels will cause more flooding, coastal erosion and contaminate fresh water. Daily high temperatures will become more extreme, with more severe floods and drought.
This book provides comprehensive insight into the challenges faced by island tourism destinations and theoretical and practical paths for built in sustainability and resiliency. It explores Island Tourism Resilience within the context of ‘Lifecycles, System Decline and Resilience’. Tourism is a key activity for many islands, and some depend on the tourism sector as a main economic activity. An exploration of islands across the globe that addresses substantial matters of ongoing sustainability and resiliency is ever important. An array of challenges including natural disasters, climate change, economic and political crises among others has been addressed in the book, with additional areas such as overtourism and COVID-19 included at the conclusion. This volume is essential reading for academics, tourism planners and policy makers seeking to develop sustainable and resilient island destinations. With a new Foreword, Introduction, Conclusion and Afterword, the chapters in this book were originally published in the journal, Tourism Geographies.
