World Refugee Day: What you need to know about the displaced and their host communities

Ede Ijjasz-Vasquez's picture

Today is World Refugee Day, a day for us all to remember how many people are moved or displaced from their homes—either within their own country or across borders.

The UN High Commissioner for Refugees (UNHCR) just announced that there were 22.5 million refugees and 40 million displaced internally due to conflicts last year, as well as many more forced to move due to natural disasters.  
Forced displacement is a crisis centered in developing countries, which host 89% of refugees and 99% of internally displaced persons. Watch a video below and learn how the crisis affects the displaced and their host communities alike around the world.
 

 


Prepare better today for tomorrow’s natural disasters – It’s possible

Ede Ijjasz-Vasquez's picture

Natural disasters cost $520 billion in losses each year and force some 26 million people into poverty each year. A volatile mix of drivers including a changing climate, conflict, and recurring natural disasters like drought – playing out in Africa and the Middle East right now where 20 million people teeter on the brink of famine – may further exacerbate this trend.
 
In fact, by 2030, without significant investment into making cities more resilient, climate change may also push up to 77 million more urban residents into poverty, according to the Investing in Urban Resilience report.

To prevent such losses, the international communities and countries – especially those highly vulnerable to climate change and nations in fragile and conflict situations – must prepare in advance for better disaster and crisis recovery. 

 

There are good examples to follow. In India, when the 2014 cyclone Phailin struck, the country invested $255 million in preparedness and worked with local communities to build shelters. This helped significantly reduce the impact of the disaster – about 1 million people were evacuated, and 99.9% of losses in life were prevented compared to the previous cyclone.
 
Positive changes like this are possible, but amid increasing disaster risks, countries need to up their game on disaster preparedness and resilient recovery, given the high stakes in terms of saving lives, livelihoods, and reducing economic impact. 
 
This week, at the third edition of the World Reconstruction Conference (WRC3) in Brussels, more than 500 experts and practitioners from the public and private sectors, NGOs, and academia are coming together to share best practices and lessons on resilient recovery, with a special focus on fragile and conflict states.
 
Watch a video to learn more about the WRC3 conference from World Bank Senior Director Ede Ijjasz-Vasquez (@Ede_WBG) and Director Sameh Wahba (@SamehNWahba), and learn how the World Bank is working to help countries prepare for and recover from disasters as a key partner, convener, and investor of choice.
 

 


Co-organized by the European Union, the World Bank’s Global Facility for Disaster Reduction and Recovery (GFDRR), the United Nations Development Programme (UNDP), and the African, Caribbean and Pacific Group of States, the event will be held in conjunction with the European Development Days 2017.
 

Mapping and measuring urban places: Are we there yet? (Part 2/2)

My previous blog post surveyed some of the recent trends in developing global measures of urbanization. In this post, I want to turn to a brief discussion for scholars and practitioners on some possible applications and areas of focus for ongoing work:
 
[Download draft paper "Bright Lights, Big Cities: a Review of Research and Findings on Global Urban Expansion"]
 
While there are a number of different maps for documenting urban expansion, each has different strengths and weaknesses in application. Coarser resolution maps such as MODIS can be used for mapping the basic contours of artificial built-up areas in regional and comparative scales. On the other hand, high-resolution maps are best suited for individual cities, as algorithms can be used to identify and classify observed colors, textures, shading, and patterns into different types of land uses. These levels of detail are difficult to use for reliable comparisons between cities as the types of building materials, structure shapes, light reflectivity, and other factors can vary widely between countries and regions.
 
Nonetheless, there are a number of applications for policymakers in this regard, from identifying and mapping green spaces and natural hazard risks to identifying and tracking areas of new growth, such as informal settlements. However, such approaches to land use detection require careful calibration of these automated methods, such as cross referencing with other available maps, or by “ground truthing” with a sample of  street-level photos of various types of buildings and land cover as reference inputs for automation. One solution to this is the use of social media and geo-coded data to confirm and monitor changes in urban environments alongside the use of high-resolution satellite imagery.
 
Nighttime light maps also have gained traction as measures of urban extent and as ways to gauge changes in economic activity in large urban centers. They are probably less useful for documenting smaller settlements, which may be dimmer or have little significant variation in brightness. It is important to correct these types of maps for “overglow” measurement effects—where certain light may “bleed” or obscure the shapes and forms of very large, bright urban areas in relation to adjacent smaller and dimmer settlements (newer VIIRs maps have made some important advances in correcting this).

Why the world’s cities are at risk – and what we can do to make them more resilient



We may not know exactly what the world will look like in two decades, but we know this: it is going to be a world of cities.
 
The global population is becoming increasingly urban, and at an astonishing rate. Each year, urban areas are growing by an average of more than 75 million people – more than the population of the world’s 85 smallest countries combined.
 
For the world’s economy, this is great news, since cities produce 80 percent of global GDP, despite currently being home to only 55 percent of the population. But it is a problem for urban infrastructure, which can’t keep up with such fast-paced growth. As a result, cities, already vulnerable, are becoming increasingly susceptible to natural disasters – from flooding and landslides that can decimate informal housing settlements, to earthquakes that can devastate power grids and water systems.
 
These risks could be disastrous for the urban poor, 881 million of whom currently live in slums (up 28 percent since 2000). And climate change – which is increasing the intensity and frequency of natural disasters – will only exacerbate the problem. For this reason, multilateral and government institutions now see resilience and climate adaptation as integral pillars of development.
 
The Swiss State Secretariat for Economic Affairs (SECO), for example, considers low-emission and climate-resilient economies to be key to global competitiveness. A recent report by the World Bank and the Global Facility for Disaster Reduction and Recovery (GFDRR) found that climate change may force up to 77 million urban residents into poverty by 2030 – unless we take action to improve the resilience of cities around the world.

A year of building sustainable communities in 12 stories

What are some of the key issues that will shape global development in 2017?

​From addressing the forced displacement crisis to helping indigenous communities, and from implementing the “New Urban Agenda” to enhancing resilience to disasters and climate change, one thing is clear: we must step up efforts to build and grow economies and communities that are inclusive, resilient, and sustainable for all—especially for the poor and vulnerable.
 
In the timeline below, revisit some of the stories on sustainable development that resonated the most with you last year, and leave a comment to let us know what you wish to see more of in our “Sustainable Communities” blog series in 2017.

Competitive cities for jobs, growth, poverty reduction and shared prosperity?

We are all aware of the statistics: cities are home to more than 50% of the world’s population, and they are growing so fast that 66 out of 100 people on earth will be urban dwellers by 2050. This, of course, will have major implications for people and poverty, climate change, and service delivery.
 
But did you also know that cities are the key drivers of global and national economic growth?
 
Currently, cities generate more than 80% of global GDP. Since the early 2000s, three-quarters of the world’s 750 largest cities have grown faster than their national economies. One of the key reasons for those cities’ success is higher productivity—as a result of their ability to attract skilled workers—as well as a high concentration of productive entrepreneurs and firms.
 
For decades, national and city leaders have also taken actions to build competitive cities, increasingly facilitating firms and industries to create jobs, raise productivity, and increase incomes over time—especially for the urban poor. They see this as the pathway to eliminate extreme poverty and to promote shared prosperity. This is particularly important in Sub-Saharan Africa and South Asia, where most of the world’s extreme poor live.

How geospatial technology can help cities plan for a sustainable future

In this video, representatives from the World Bank, GEF, and City of Johannesburg discuss the impact of geospatial tools on urban planning.

Many urban residents these days will find it hard to imagine a life without mobile apps that help us locate a restaurant, hail a cab, or find a subway station—usually in a matter of seconds. If geospatial technology and data already make our everyday lives this easier, imagine what they can do for our cities: for example, geospatial data on land-use change and built-up land expansion can provide for more responsive urban planning, while information on traffic conditions, road networks, and solid waste sites can help optimize management and enhance the quality of urban living.

The “urban geo-data gap”
 
However, information and data that provide the latest big picture on urban land and services often fail to keep up with rapid population growth and land expansion. This is especially the case for cities in developing countries—home to the fastest growing urban and vulnerable populations.

Success when we deemed it failure? Revisiting sites and services 20 years later

Between 1977 and 1997, the World Bank supported “sites and services” projects in 27 cities across India
A freshly-minted architect stood staring at a sea of toilets. Row after row of them, on small “housing plots” meant for low-income families who would build their house incrementally as their incomes and savings grew. The neighborhood was “planned” and provided with services—under a World Bank-supported “sites and services” project—to serve as the anti-thesis of and an antidote to the slums that were, at the time, increasingly becoming the only housing option for low-income families.

It was 1980 and the architect, Barjor Mehta, was deeply disappointed. There were no houses, no people and no chance that they would ever come, given the seemingly god-forsaken location—in an area called Arrumbakkam—so far from the city center in Madras (now Chennai). Having just completed his thesis on housing, he wrote a scathing news article in the Times of India denouncing the sites and services approach. Barjor wasn’t alone in his critique, and by the mid-1990s the World Bank had almost entirely abandoned such projects.

In October 2015, Barjor, now Lead Urban Specialist at the Bank, invited me to revisit Arumbakkam and other neighborhoods developed, between 1977 and 1997, under four Bank-supported sites and services projects: With my colleagues Kate Owens and Andrea Rizvi, I visited 15 of the 28 sites developed in Chennai and Mumbai. We also reviewed archival material, analyzed satellite images, and recently presented our preliminary findings. Now, Barjor and I agree that previous assessments of failure may have been both premature and erroneous. Why?

Of tigers and elephants: The rise of cities in Asia

Over the next decade and a half the world will add a staggering 1.1 billion people to its towns and cities. About one half of this urbanization will happen in the regions of East and South Asia.
 
If history is any guide, this growth in urban population will provide tremendous opportunities for increasing prosperity and livability. One can look at the successes of a few Asian cities such as Tokyo, Seoul, and Singapore to demonstrate how, with the assistance of good policies, urbanization and economic development go hand-in-hand. More generally, no major country has ever reached middle-income status without also experiencing substantial urbanization.
 
Yet cities can grow in different ways that will affect their competitiveness, livability, and sustainability. The more successful cities of Asia have been effective at creating opportunities, increasing productivity, fostering innovation, providing efficient and affordable services for residents, and enhancing public spaces to create vibrant and attractive places to live. But many, many, more cities have neglected fundamental investments in critical infrastructure and basic services, and have mismanaged land, environmental and social policies. This has resulted in traffic congestion, sprawl, slums, pollution, and crime.
 
Among the many complexities of urban development that have contributed to success, two critical factors stand out – investing in strategic urban planning, and in good urban governance.

How can South Asian countries make the most of urbanization?

Ede Ijjasz-Vasquez's picture
The World Bank recently completed a comprehensive study that looks into the specifics of urban development across South Asia, and provides policy recommendations to help countries in the region build more prosperous, livable cities. One of the most innovative features of this South Asia Urbanization Review is that it relies extensively on geospatial mapping and satellite imagery, especially night-time light data. This approach allowed World Bank experts to overcome the lack of reliable, cohesive urbanization data across South Asian countries, and to measure the footprint of urban settlements in a consistent way. They quickly found out that urban expansion in South Asia remains largely unplanned, and often spreads to areas that are not officially considered urban - prompting them to describe urbanization in the region as "hidden" and "messy". In this video, Peter Ellis provides a more detailed overview of the main findings, and describes how South Asian countries have a unique opportunity to get urbanization right as their cities continue to grow.
