How to manage urban expansion in mega-metropolitan areas?

Philip E. Karp's picture
 


As the world becomes increasingly urbanized, the number of megacities is growing rapidly.

Today there are 37 cities worldwide with populations of greater than 10 million, and 84 with populations greater than five million. More than three quarters of these cities are in developing countries. Together with their surrounding metropolitan areas, these cities produce a sizable portion of the world’s wealth and attract a large share of global talent.

These megacities face a series of common challenges associated with managing urban expansion, density, and livability—in a manner that takes advantage of the benefits of productive agglomerations, while mitigating the disadvantages of such high degrees of congestion and urban density.

Moreover, like other metropolitan areas, megacities face challenges of effectively coordinated planning, infrastructure development, and service delivery across multiple jurisdictions. Indeed, the New Urban Agenda issued at the Habitat III conference in 2016 identified metropolitan planning and management as one of the most critical needs to ensure sustainable urbanization.

Innovation in the air: using cable cars for urban transport

Invented over a century ago for exploring mountainous regions, aerial cable cars have recently made an appearance in several big cities, where they are being used as an alternative to conventional urban transport modes. This technology uses electrically-propelled steel cables to move suspended cars (or cabins) between terminals at different elevation points.
 
The tipping point. The emergence of cable cars in urban transport is fairly new. Medellín, Colombia pioneered the use of cable cars for urban transport when it opened its first “Metrocable” line in 2004. Since then, urban cable cars have grown in popularity around the world, with recent projects in Latin America (Rio de Janeiro, Caracas, Guayaquil, Santo Domingo, La Paz, and Medellín), Asia (Yeosu, South Korea, Taiwan, Hong Kong), Africa (Lagos, Constantine), and Europe (London, Koblenz, Bolzano).  Cable cars can be an attractive urban transport solution to connect communities together when geographical barriers such as hills and rivers make other modes infeasible.

Africa is paving the way to a climate-resilient future

Since the presentation of the World Bank’s first Africa Climate Business Plan at the COP 21 in Paris in 2015 and the Transport Chapter in Marrakech in 2016, a lot of progress has been made on integrating climate adaptation and mitigation into our transport projects.

The World Bank initially committed about $3.2 billion toward mainstreaming climate action into transport programs in Sub-Saharan Africa in the form of infrastructure investments and technical assistance. Following the Paris Agreement, and building on African countries’ Nationally Determined Contributions (NDCs), the size of this portfolio grew to $5 billion for 2016 to 2020.  In 2017, the institution added another $1.9 billion to that amount, bringing the total to $6.9 billion in projects with climate co-benefits— more than twice the size of the original portfolio. These investments will help improve the resilience of transport infrastructure to climate change and improve the carbon footprint of transport systems.
 
Climate change has already started to affect African countries’ efforts to provide better transport services to their citizens.  African transport systems are vulnerable to multiple types of climate impact: sea level rise and storm surge, higher frequency and intensity of extreme wind and storm events, increased precipitation intensity, extreme heat and fire hazard, overall warming, and change in average precipitation patterns. The increased frequency and intensity of extreme climate event challenges the year-round availability of critical transport services: roads are damaged more often or are more costly to maintain; expensive infrastructure assets such as ports, railways or airports can be damaged by storms and storm surges, resulting in a short  life cycle and capacity than they were originally designed for. Critical infrastructure such as bridges continue to be built based on data and disaster risk patterns from decades ago, ignoring the current trend of increased climate risk. For Sub-Saharan Africa alone, it is estimated that climate change will threaten to increase road maintenance costs by 270% if no action is taken.

How Maputo is driving new forms of collaboration between citizens and city governments

The true test is whether open data leads to improvements in public services.


Maputo, Mozambique’s capital, celebrated its 130th anniversary in November. But that’s not its only milestone: This year, it became only the second city in sub-Saharan Africa to have its own open data platform—one of many exciting results to come out of its Open Data Roadmap.

Creating “Solid Ground” for gender equality in land access

Despite the fact that women represent about half of the global population, produce the majority of global food supply, and perform 60% to 80% of the agricultural work in developing countries, women own less than 20% of land worldwide.

Written laws often fall short of adequately protecting women’s tenure rights; while in some countries, formal national laws explicitly discriminate against women. In post-disaster rehabilitation and reconstruction, women face particular hurdles to secure tenure and shelter. Even in areas with strong protections of equality and non-discrimination, displaced women often struggle to assert their property rights.

On March 8, 2016, on the occasion of International Women’s Day, Habitat for Humanity International launched its first global advocacy campaign, “Solid Ground,” which envisions a world where everyone has access to land for shelter. Promoting gender equality and addressing inequitable or unenforced laws, policies, and customary practices affecting women’s rights to security of tenure and inheritance, has been a primary focus of the campaign.

Now mid-way through the campaign, Solid Ground has grown to include 37 national Habitat for Humanity organizations, 17 partner organizations, an active microsite solidgroundcampaign.org (and in Spanish, SueloUrbano.org), and has provided direct financial assistance to country programs working on gender and land issues. In its first year, over 1.3 million people are projected to have improved access to land for shelter through the Solid Ground campaign with a goal of reaching 10 million people, especially women.

Through a variety of efforts to build capacity, mobilize allies, influence policymakers, and work together with our partners, we are seeing signs of progress being made to achieve successful outcomes in helping facilitate women’s land ownership and empowering women to understand and achieve their rights. A sampling of some strategies, cases, and upcoming plans are highlighted below. 

Good fences make good neighbors

The members of the community in the Bulugolla village in Sri Lanka breathed a sigh of relief. It was the month of October and the rice harvest had gone well. The rains had been plentiful and their meddlesome neighbors (seen in picture above) were abiding by their boundaries. This has not always been the case.

As the head of the village explained, “We depend upon a rice harvest to earn our livelihood. While we culturally and traditionally have lived in harmony with elephants, we cannot survive without our paddy farms and so we have to keep the elephants out”.

Human wildlife conflict is currently one of the greatest conservation challenges. As human populations grow, wildlife habitat shrink and humans and wildlife come in contact with each other as they compete for resources. In addition, wildlife such as elephants cannot be limited to the boundaries of protected areas as many protected areas can only support a certain number of elephants. In Sri Lanka, most elephant live outside protected areas amidst paddy fields, community villages, highway railways and other development infrastructure that is intended to support the growing human population. Conflict is inevitable but failure to reduce it will result in extinction of wildlife species.   

Migration: The future depends on our actions today

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.

Migration, Remittances and Diaspora Data: Need for International Cooperation

Despite that several countries have made a call of action for enhancing data collection and capacity building of the national statistical systems to improve migration data, there has not been much progress. The High Level on International Migration in 2013 “emphasized the need for reliable statistical data on international migration, including when possible on the contributions of migrants to development in both origin and destination countries.”

Cities of Refuge: Bringing an urban lens to the forced displacement challenge

The Syrian conflict has reached the grim milestone of becoming the largest displacement crisis since World War II, with over half of the country’s pre-war population having left their homes since 2011—a particularly sobering statistic as we observe International Migrants Day on December 18, 2017 today.

For many of us, the Syrian crisis brings to mind images of refugee families blocked at European borders and sprawling humanitarian camps. Yet the majority of those fleeing the violence have remained in cities inside Syria and in neighboring countries, in the hopes of reaching safety, and accessing better services and jobs.

This shift from camps to cities and towns has critical implications for how to effectively deal with the forced displacement challenge—and it is not confined to Syria, but a reality across many countries affected by conflict in the Middle East and beyond.

Let them come and have a job

The world is worried about migration and forced displacement. In October, the Development Committee Communiqué highlighted the need for action to address challenges – climate change, migration and forced displacement, global health, as well as fragility, conflict and violence (FCV) – that “threaten” all countries. Migration however, is not a threat. If well managed, migration can be beneficial for countries of origin, destination and migrants themselves.
