Our country is well-served by this ambition. Climate change is a global phenomenon that largely impacts urban life. Supreme Court weighs in on cities' climate change lawsuits. United Nations (2017) Resolution adopted by the General Assembly on 6 July 2017, United Nations Economic and Social Council (2020), concentrating more impoverished peoples in cities, largely due to cement's outsized role in climate change, Intergovernmental Panel on Climate Change, United States withdrawal from the Paris agreement, Learn how and when to remove this template message, "Climate change and cities: a prime source of problems, yet key to a solution", "Cities: a 'cause of and solution to' climate change", "Summary for Urban Policymakers – What the IPCC Special Report on 1.5C Means for Cities", "With people crowding into urban areas, how can cities protect themselves against climate change? [32][33][34], Founded in 2014, the organization received one million dollars in start-up funding from the Clinton Global Initiative to support the founding mayors' efforts to organize cities in advance of the signing of the 2015 Paris Agreement.[35]. At the same time, the exposed infrastructure and prevalent coastal location of many cities makes them common targets for climate change impacts such as sea level rise and fiercer storms. [1] Cities are also one of the most vulnerable parts of the human society to the effects of climate change,[2] and likely one of the most important solutions for reducing the environmental impact of humans. Cities are central to the fight against climate change, but the IPCC recently noted that many cities — and particularly those in the developing world — lack the institutional, financial and technical capacities needed to switch to low emission development paths. The research perspective of cities and climate change, started in the 1990s as the international community became increasingly aware of the potential impacts of climate change. Cutting emissions will also reduce local pollution from industries and transport, thus improving urban air quality and the health of city dwellers. In addition, the module will look at how climate change adaptation and mitigation can be considered in urban planning and identify concrete measures. Cities in different parts of the world face different, unique challenges and opportunities in the face of climate change. [3] Moreover, because of processes that create climate conflict and climate refugees, city areas are expected to grow during the next several decades, stressing infrastructure and concentrating more impoverished peoples in cities.[4]. The three "means of achieving" targets include: Strong national and regional development planning; implement policies for inclusion, resource efficiency and disaster risk reduction; support least developed countries in sustainable and resilient building.[44][46]. Opt not to print. [24] To achieve sustainable development and climate resilience in cities in Africa, and elsewhere, it is important to consider these urban-rural interlinkages. In cooperation with partners, UNEP assists national and local governments by raising awareness, organizing workshops and trainings, developing evaluation tools and involving cities in international meetings on climate change. However, cities are not just drivers of climate change, they are also particularly affected by it. More than half of the world's population is in cities, consuming a large portion of food and goods produced outside of cities. [14], Part of the reason that cities are being studied, is that cities that invest heavily in experiments of large policies, that can be adopted by larger jurisdictions (such as San Diego's advanced urban planning practices which could be applied elsewhere in the United States). A 2020 study of US cities found that 45 of the 100 largest cities in the U.S. had made commitments by 2017, which led to a reduction of 6% of U.S. emissions by 2020. [20] This rapid urbanization, coupled with the many interlinked and complex challenges as a result of climate change, pose a significant barrier to Africa's sustainable development. All three work closely with the 13-member Steering Committee, the Board of Directors[38] and professional staff. [15][16] Multiple scholars approach this in different ways, but describe this "urban laboratory" environment for testing a wide variety of practices. [5] Climate adaptation and mitigation investments in cities will be important in reducing the impacts of some of the largest contributors of greenhouse gas emissions: for example, increased density allows for redistribution of land use for agriculture and reforestation, improving transportation efficiencies, and greening construction (largely due to cement's outsized role in climate change and improvements in sustainable construction practices and weatherization). Rising global temperatures causes sea levels to rise, increases the number of extreme weather events such as floods, droughts and storms, and increases the spread of tropical diseases. Infographic In general, city dwellers live in areas most prone to the effects of climate change. Climate Change is one of the most pressing challenges of our times. If we redesign our cities to be circular, regenerative and equitable, not only can we eliminate most of the impact humanity is causing globally — we also can create a future to look forward to. Local involvement through “climate-conscious” urban planning and management can help achieve national climate goals and minimise tradeoffs between environmental and economic priorities at local levels. [37] Created and led by cities, C40 is focused on tackling climate change and driving urban action that reduces greenhouse gas emissions and climate risks, while increasing the health, wellbeing and economic opportunities of urban citizens. Cities, while being the main cause of climate change, are also the most affected. Most Europeans now live in cities, so the choices we make about urban infrastructure will have a large influence on how well we cope with climate change. This guide on climate change adaptation in cities is intended to offer mayors and other city officials, in developing countries, practical guidance on how to respond to the challenges of climate change adaptation in their cities. They often lie on coasts, rivers, deltas or mountain slopes and are thus exposed to huge risks. By 2050, more than 70% of the population – 6.4 billion people – is projected to live in urban areas. The SDG 11 is to "Make cities inclusive, safe, resilient and sustainable". 5 Global Cities Tackling Climate Change and Inequality From sustainable urban farming to infrastructure combating floods, projects launched by these global cities are winning plaudits. In some cities, it’ll be like moving two states south. UN-Habitat's Cities and Climate Change Initiative (CCCI) seeks to enhance the preparedness and mitigation activities of cities in developing countries. [23], Climate impacts in rural areas, such as desertification, biodiversity loss, soil erosion and declines in agricultural productivity, are also driving rural-urban migration of poor rural communities to cities. [31], Cities play an important role in investing in climate innovation in the United States. [1][2] More than half of the world's population is in cities, consuming a large portion of food and goods produced outside of cities. [29] Urban water access is particularly critical in South Asia as it remains home to more than 40% of the world’s poor (living on less than USD 1.25 per day) and 35% of the world’s undernourished. Are you sure you want to print? [11] Urban studies scholars Michael Hebbert and Vladmir Jankovic argue that this field of research grew out of a larger body of research on the effects of urban development and living on the environment starting as early as the 1950s. Over 90% of all urban areas are coastal, putting most cities on Earth at risk of flooding from rising sea levels and powerful … [19] It is estimated that by 2030, more than one billion Africans will live in cities.
