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 ...
Place matters for productivity and prosperity. Myriad factors support a successful place, including not only the hard infrastructure such as roads, but also the softer elements such as worker skills, entrepreneurial ability, and well-functioning institutions. History suggests that prosperous places tend to persist, while “left behind†? regions, or those hurt by climatic, technological, or commercial shocks, struggle to catch up. This division gives rise to demands to “do something†? about the subsequent spatial inequality. Such pressures often result in costly spatially targeted policies whose outcomes disappoint because of a lack of analysis of the underlying barriers to growth and ...
Climate change is unfolding amid the greatest information and communication revolution in human history. From e-commerce and social media to smart manufacturing and precision farming, digital technologies have become prevalent in all aspects of economic and social life. Digital technologies also have the potential to shape climate change action. Green digital transformation can help countries adapt e¬ffectively to the impacts of climate change and create greener growth pathways. Doing this means combining a focus on digital transformation and inclusion with a strategic and sustainable use of digital technologies to address climate change. Green Digital Transformation: How to Sustainably Close the Digital Divide and Harness Digital Tools for Climate Action illuminates the channels through which digital technologies intersect with climate change, and it proposes a path to low-emissions applications of digital technologies to help countries mitigate and adapt to climate change.
This Staff Climate Note is part of a series of three Notes (IMF Staff Climate Note 2022/001, 2022/002, and 2022/003) that discuss fiscal policies for climate change adaptation. A first Note (Bellon and Massetti 2022, henceforth Note 1) examines the economic principles that can guide the integration of climate change adaptation into fiscal policy. It argues that climate change adaptation should be part of a holistic, sustainable, and equitable development strategy. To maximize the impact of scarce resources, governments need to prioritize among all development programs, including but not limited to adaptation. To this end, they can use cost-benefit analysis while ensuring that the decision-ma...
One small town, two "thousand-year floods" in the span of two years: how does a community become resilient in the face of the ever-increasing risks of climate change? Small towns across America and around the world face mounting challenges with flood risk, a result of not only climate change but also poorly adapted landscapes, sprawl, overdevelopment and poor planning. After the Floods is about Ellicott City, a small town in central Maryland that experienced two devastating flash floods just 22 months apart. Despite the town's many advantages—wealth, access to expertise, a mobilized community, and a stout identity steeped in 250 years of history—Ellicott City found itself mired in a deep...
Cities in Sub-Saharan Africa are experiencing rapid population growth. Yet their economic growth has not kept pace. Why? One factor might be low capital investment, due in part to Africa’s relative poverty: Other regions have reached similar stages of urbanization at higher per capita GDP. This study, however, identifies a deeper reason: African cities are closed to the world. Compared with other developing cities, cities in Africa produce few goods and services for trade on regional and international marketsTo grow economically as they are growing in size, Africa’s cities must open their doors to the world. They need to specialize in manufacturing, along with other regionally and global...
Policy makers across the Middle East and North Africa have for many years articulated plans to integrate their people spatially and economically. Wishing to bring communities together and narrow economic gaps, governments have made large capital investments in transport corridors and “new cities.†? Hoping to provide jobs in places with little economic activity, governments have designated new industrial zones supported by spatially targeted business incentives. Yet the results of these place-based initiatives in MENA are limited. The disparities between capital cities and lagging areas, and between richer and poorer quarters of cities, remain stark. Across much of the region, a fortunate...
Between 1970 and 2021, the number of people living in cities increased from 1.19 billion to 4.46 billion, while the Earth’s surface temperature climbed by 1.19 degrees Celsius above its preindustrial levels. Because of the prosperity they helped generate, cities have been a major cause of this climate change. However, it is also in cities that many of the solutions to the climate crisis—in terms of both adaptation and mitigation—will be found, not least because by 2050, almost 70 percent of the world’s population will call cities home. As such, cities are the key to arguably the greatest public policy challenge of our times. To take stock of how green, how resilient, and how inclusiv...
Adaptation to climate change is a necessity for advanced and developing economies alike. Policymakers face the challenge of facilitating this transition. This Note argues that adaptation to climate change should be part of a holistic development strategy involving both private and public sector responses. Governments can prioritize public investment in adaptation programs with positive externalities, address market imperfections and policies that make private adaptation inefficient, and mobilize revenues for, and distribute the benefits of, adaptation. Although the choice of what should be done and at what cost ultimately depends on each society’s preferences, economic theory provides a useful framework to maximize the impact of public spending. Cost-benefit analysis, complemented by the analysis of distributional effects, can be used to prioritize adaptation programs as well as all other development programs to promote an efficient and just transition to a changed climate. While compensations may be needed to offset damages that are either impossible or too expensive to abate, subsidies for adaptation require careful calibration to prevent excessive risk taking.
This book explores economic concepts related to disaster losses, describes mechanisms that determine the economic consequences of a disaster, and reviews methodologies for making decisions regarding risk management and adaptation. The author addresses the need for better understanding of the consequences of disasters and reviews and analyzes three scientific debates on linkage between disaster risk management and adaptation to climate change. The first involves the existence and magnitude of long-term economic impact of natural disasters on development. The second is the disagreement over whether any development is the proper solution to high vulnerability to disaster risk. The third debate ...
