In June 2015, after two days of heavy rain, flood water washed away Sarah’s small store in Accra, which provided for her family of three (1). The flood that hit the city in June 2015 affected around 53,000 people in the city and caused an estimated US$100 million in damages. Slum areas in the Odaw basin were among the worst hit.
Municipalities need recurrent property taxes to finance service delivery
The ability for cities to raise revenues in a non-distortionary way for effective urban service delivery and infrastructure is essential to realizing the potential of urbanization. As most benefits from these investments will be capitalized in surging land values, recurrent taxes on land and other real property can be an incentive-compatible financing method. In developing countries, taxes on land and property are still far below those of developed countries, even in relative terms. Instead, cities often rely heavily on land transaction taxes, but these impose frictions on land market operations, push transactions into informality, and create incentives for fraudulent under-declaration of sales values.
Many of today’s increasingly complex development challenges, from rapid urban expansion to climate change, disaster resilience, and social inclusion, are intimately tied to land and the way it is used. Addressing these challenges while also ensuring individuals and communities are able to make full use of their land depends on consistent, reliable, and accessible identification of land rights.
In the past two decades, development policy has aimed to involve communities in the development process by encouraging the active participation of communities in the design and implementation of projects or the allocation of local resources. The World Bank alone has provided more than $85 billion for participatory development since the early 2000s.
Around 250 million migrants currently live outside their countries of birth, making up approximately 3.5 percent of the world population. Despite the widespread perception of a global migration crisis, this ratio has stayed remarkably stable since the end of the Second World War and lags well behind other major metrics of globalization – international trade, capital flows, tourism etc. A more remarkable statistic is that refugees, at around 15 million, account for 6 percent of the migrant population and only 0.2 percent of world population. In other words, we can fit all refugees in the world in a city with an area of 5000 square kilometers – roughly the size of metropolitan Istanbul or London or Paris – and still have some space left over.
Massive flooding from storm surges is a major threat to lives and property in low-lying coastal areas during cyclones. Recent examples of devastating cyclone-induced storm surges include Haiyan 2013 (5.2m or 17 feet), Aila 2009 (4m/13ft), Ike 2008 (4.5m-6m/15-20 feet), Nargis 2008 (more than 3m/10ft), Sidr 2007 (4m /13ft), Katrina 2005 (7.6m-8.5m/25-28 feet). The impacts are particularly disastrous when storm surges strike densely populated coastal areas.
Cities now drive as much as 80% of global GDP. They also consume close to two-thirds of the world’s energy and produce over 70% of global greenhouse gas emissions. And given the sheer scale of urban growth worldwide, these numbers are only expected to increase. Not surprisingly, cities are rapidly becoming the epicenters of economic growth, spurring innovation, fortifying institutions and nurturing the social fabric of dynamic communities.
