Five lessons on affordable housing provision from Indonesia

Dao Harrison's picture
When first-time homeowner Dewi moved into her new house in the Yogyakarta area a year ago, thanks to a government subsidy program, she thought: everything is perfect.
 
Well, not quite. Located an hour away from the city center, Dewi’s house is far from employment opportunities, shopping, and schooling for her two children. Two years after completion, more than half the housing development remains unoccupied. Because the house is not connected to the local water system, Dewi buys water twice a week. When seasonal floods are underway, the heavy rains impede access to her house.



Providing affordable and adequate housing has become a top policy priority for the government of Indonesia with the launch of Satu Juta Rumah (One Million Homes) program. Previous efforts to address the demand for affordable housing – a function of both new annual demand creation and an unmet housing deficit – had not effectively improved housing outcomes at the scale necessary.

But should homeownership volume be the sole indicator of a successful housing subsidy program? Is it possible to have a program that meets the government’s needs to be fiscally and economically cost effective, while also responding to the private market as well as the needs of residents?
 
Options are being explored. The recently approved National Affordable Housing Program Project (NAHP), for example, aims to innovate the affordable housing market by addressing bottlenecks and actively engaging the private sector in delivering for unserved segments. So far, Indonesia’s efforts provide valuable lessons. The lessons are:

“Better Planning, Better Cities” – Cities to share smart solutions to urban sustainability

There is strength in numbers, the old idiom goes. Indeed, history shows that collaboration fosters ideas and results. Next week, the Global Platform for Sustainable Cities, or GPSC, will convene in New Delhi, India, to again share ideas and build on their collective vision: to work towards shaping cities that are sustainable, thriving, and inclusive through the decades ahead.
 
The gathering starting on October 30 is only the GPSC’s second annual meeting, as we launched the platform just last year in Singapore. Yet the 27 participating cities across 11 countries—and more members are very welcome—are moving ahead with confidence, embarking on innovative programs to realize their vision and galvanizing their national governments to establish platforms of their own. China, Malaysia, and India in Asia, Paraguay and Brazil in Latin America, and other participating cities are actively pursuing sustainable urbanization.
 
This strength in numbers is made possible by staunch supporters. The Global Environment Facility (GEF) is integral to the progress of the GPSC, and numerous partners such as UN agencies, development banks, and civil society organizations contribute to its success—amongst them the World Resources Institute, ICLEI (Local Governments for Sustainability), and the C40 Cities Climate Leadership group (C40).
 
What are the aims of the GPSC? Forging a shared vision for urban sustainability is its overarching goal, and this achievement would not be possible without connecting cities. 
 

In more concrete terms, the GPSC aims to be a global knowledge repository on integrated urban planning – both best practices and lessons learned. The newly launched GPSC website, www.thegpsc.org, hosts a collection of datasets, indicators, and analyses on trends in urbanization. This library of information assists cities in identifying the gaps in urban infrastructure and the provision of basic services. The data collected will improve the cities’ capacity to monitor and report the status of their “sustainability,” and to better formulate and implement strategies.
 
The GPSC’s 2nd annual meeting is organized around the theme of “Better Planning, Better Cities - Smart Solutions to Urban Sustainability,” and this second meeting will focus on using a data-driven approach for planning action. The many scheduled events will follow this approach, including the Mayor’s Roundtable, high-level panel discussions, and in-depth learning events. 

Understanding transit-oriented development through bike-sharing big data

As one of over 20 million people who work and live in Beijing, China, I used to find commuting to work in rush-hour traffic rather painful. However, things have changed dramatically since last year. Now I can bypass the traffic by riding a shared bike to the closest metro station and make better use of public transit. Similar change is happening to my family and friends.

The unprecedented booming of dockless shared bikes in China presents a promising solution to the “last-mile problem” that has perplexed city planners for years: providing easier access to the mass transit system while ensuring good ridership. Thanks to the GPS tracking device installed on thousands of dockless shared bikes, city planners in China are now equipped with new and better information to analyze the demand for—and the performance of—public transit systems. For the first time, city managers can clearly map out the attractiveness and accessibility of metro stations by analyzing individual-level biking trips.

This innovation is good news to efforts to build more livable, sustainable cities through transit-oriented development (TOD). For example, to support the recently launched GEF Sustainable Cities Integrated Approach Pilot Project, we have been working with Mobike, a major bike-sharing company, to conduct an analysis utilizing the data of biking trips around metro stations in our project cities. Below are a few interesting observations:
  • Revisiting the scope of TOD. A commonly accepted textbook definition of the core area of TOD is an 800-meter radius around the metro station or other types of public transit hubs. This definition is based on the distance that can be reached by a 10-minute walk. However, the actual catchment of a metro station can reach a 2-3 km radius when biking prevails, as in Demark and Netherland. Our analysis illustrates that a big chunk of biking trips around metro stations even go beyond the 3km radius (see bright blue traces in Figure 1 below). This indicates that the spatial scope of planning and design around the metro stations should be contextualized. Accordingly, the price premium associated with adjacency to public transit service is more likely to be shared by a broader range of nearby real estate properties than expected.

透过共享单车大数据了解公共交通导向的开发(TOD)

作为在北京工作和生活的两千多万人中的一员,我曾经常为高峰时段上下班发愁。不过从去年开始情况发生了变化。现在我可以骑着共享单车避开拥堵,到最近的地铁站搭乘地铁,更充分享受地公共交通服务的便利。我的亲朋好友也有类似的经历。
 
无桩共享单车在中国前所未有的蓬勃发展,为多年来困扰城市规划者们的“最后一公里问题”提供了颇有希望的解决方案:既让公共交通系统更便于使用,又能保证良好的客流量。许多无桩共享单车安装了GPS跟踪设备,为城市规划者分析公共交通系统的需求和绩效提供了更精准的新的数据来源。通过分析个人骑行数据,城市管理者第一次可以清楚地了解各个地铁站的吸引力和可达性。
 
这项技术创新对于通过公共交通导向开发(TOD)建设更宜居、可持续城市的工作无疑是个好消息。例如,为了支持最近启动的全球环境基金(GEF)“可持续城市综合方式示范项目”,我们与中国一家主要的共享单车公司“摩拜单车”合作,使用项目城市地铁站周边的骑行路线数据开展研究。以下是一些有意思的发现:
  • 重新审视TOD的范围。关于TOD的核心区域,普遍接受的教科书定义是围绕地铁站或其他公共交通枢纽800米半径的范围。这个定义是基于10分钟步行可达的距离。然而,在骑行普及的丹麦、荷兰等地,地铁站的实际覆盖半径可达2-3公里。我们的分析发现,地铁站周边有一大部分骑行的距离甚至超过3公里半径(见下图1中的亮蓝色轨迹)。这说明地铁站周边区域规划和设计的空间范围应该根据当地环境而定。相应地,由于靠近公共交通服务设施而产生的增值,其影响的房地产范围很可能超出预期。

Many urban planners may know the success stories of Curitiba, Singapore or London realizing transit-oriented development (TOD). However, TOD is still very new in Sub-Saharan Africa. Although this concept of leveraging on major transit infrastructure to affect integrated land-use development for greater benefits may be gaining more recognition, there are few examples of successful TOD in Sub-Saharan Africa beyond a couple of South African cities, such as Cape Town and Johannesburg.

Dar es Salaam, Tanzania now has the perfect opportunity to become a pioneer on transit-oriented development.

Dar es Salaam, the largest city in Tanzania with a population of 4.6 million, is expected to become a mega city by 2030 with a population over 10 million. However, its growth has been largely shaped by informality, coupled with a lack of hierarchy in roads and transit modes. It is increasingly difficult to get around the city without being stuck in traffic for hours. The complex and fragmented institutional structure of Dar es Salaam compounds the challenges, making management of the city complicated and less effective.

From Istanbul to Manila—different fault lines, similar challenges

Elif Ayhan's picture
 “It’s not the mountain we conquer, but ourselves.” This was the response given by Sir Edmond Hillary when asked how he and his companion Tenzing Norgay became the first to summit Mt Everest, when so many before had failed. He believed we could all overcome our biggest challenge simply by deciding to act.

Is it possible for the same sentiment to be applied by government leaders – leaders who have the privilege and responsibility to preside over some of the world’s largest and most dynamic cities, especially those that share a common challenge in terms of seismic risk? Metro Manila, the megacity of the Philippines, the seat of government, and the engine of the national economy, has been destroyed numerous times over the last 500 hundred years by earthquakes, and currently sits upon a fault that is overdue to move. Istanbul, with world-class cultural heritage sites treasured by all, also sits near major fault lines expected to move any day. Tokyo and Wellington, the heart of government, culture, and history, also share exposed locations close to major fault lines.

In Wellington, decades of work – including the current Get Ready week! – have aimed to prepare the city for the next “big one”; but compared to the burgeoning megacities of Manila, Tokyo, or Istanbul, it is a small hill to conquer. How do you prepare these megacities with population of up to 15 million people? How do you climb the mountain of needs to build resilience? According to Sir Hillary, the answer is simple, you need to take the decision to accomplish something extraordinary.

In September 2017, the World Bank and the Global Facility for Disaster Reduction and Recovery (GFDRR) through the Japan-World Bank Program for Mainstreaming Disaster Risk Management in Developing Countries supported a knowledge exchange between Turkey and the Philippines focused on the challenge of building seismic resilience in megacities with high urbanization. For the World Bank, it was clear from the start that seismic risk is a priority on the Urban Resilience Agenda, when Johannes Zutt was able to explain to the visiting delegation the technical details of how base isolation is used to protect critical hospitals in Istanbul. The delegation saw impressive progress made by Turkey and Istanbul, from revised institutional frameworks, strengthened preparedness and response capabilities, and retrofitted schools and hospitals to adapted municipal e-services that ensure that the construction of resilient new buildings are approved fast and with the right safety checks. While massive seismic risk still exists within Istanbul, visible and concrete actions are also underway to improve the safety of its citizens.

“At 14:28:04 on May 12, 2008, an 8.0 earthquake struck suddenly, shaking the earth, with mountains and rivers shifted, devastated, and parted forever….” This was how China’s official report read, when describing the catastrophic consequences of the Sichuan earthquake, which left 5,335 students dead or missing.
 
Just two years ago, in Nepal, on April 25, 2015, due to a Mw 7.8 earthquake, 6,700 school buildings collapsed or were affected beyond repair. Fortunately, it occurred on Saturday—a holiday in Nepal—otherwise the human toll could have been as high as that of the Sichuan disaster, or even worse. Similarly, in other parts of the world—Pakistan, Bangladesh, Philippines, Haiti, Ecuador, and most recently Mexico—schools suffered from the impact of natural hazards. 
 
Why have schools collapsed?

“The waterfront isn’t just something unto itself. It’s connected to everything else,” said Jane Jacobs, a prominent urbanist.
 
This connection is twofold; it refers to the relationship between cities and their waterfronts – as ever-changing as cities themselves.
 
Evolving from its past definition during the industrial era as a city’s service yard, the urban waterfront has, in recent decades, taken on new meanings.

On one hand, the waterfront is playing a more significant role in transforming the urban fabric of a city or even reshaping a city’s identity.
 
On the other hand, successful urban waterfronts have also demonstrated how city resources – such as available land, cleaner water, historic preservation, and urban revitalization – can be unlocked and realized, and how these elements can be integrated into the city and public life.

The last few weeks have been a stark reminder of how natural disasters can undermine precious development progress in an instant. Images of incredible devastation in the Caribbean wrought by a record-breaking Atlantic hurricane season, collapsing buildings in Mexico during a violent series of earthquakes, and massive monsoon flooding in South Asia that claimed hundreds of lives have resulted in an outpouring of support from the international community.
 
Unfortunately, scenes like these are becoming more routine. The impacts of climate change are becoming increasingly visible, and rapid urbanization is concentrating risk in vulnerable regions of the world.
 
Just consider the following statistics:
