可持续城市摄影作品竞赛的出发点很简单。我们想要了解世界各地的人们听到“可持续城市”这个词会“看”到什么。

   

可持续城市全球平台从全球四十多个国收到就九十多张参赛作品,内容发人深省。

摄影师通过照片试图传递的是一种需求:对能使城市恢复能力更强、更加可持续的基础设施的迫切需求,或者追求为所有人建设可持续社区的绿色理想的需求。

今天是世界城市日,是最适合与你们分享本次摄影竞赛十位入围者名单的日子, 这些入围者中包括三位获奖者和一位气候行动荣誉奖获得者。
 
人们几乎可以从Yannick Folly的获奖作品中感受到贝宁城市的混乱和汽车尾气的味道,汽车沿着狭窄的巷子艰难爬行,与摩托车和行人挤在一起。

日复一日的发展,我们的世界一直在变化。看看充满活力的贝宁集市就能感受到这种变化。#SustainableCities

这张照片提醒人们城市是由人组成的。任何建设可持续城市的解决方案对城市居民而言必须是合理的,因为每天行走在城市街道上的人是他们每天。

 

这种渴望在其他作品中也显而易见。

 

尽管很多摄影师来自世界各地的发展中国家,然而,其中相当一部分分享的却是在我们看来的环境友好型城市:新加坡、阿姆斯特丹、伦敦、巴黎等的照片。我们看到了很多发达国家公园的照片,都在传递同一个信息: 这样的绿色空间和人行道正是我们希望城市拥有的。

很多作品也反映了人们梦寐以求的城市和大部分人实际生活在其中的城市的巨大差别。
 
我们收到了很多可能被许多人归类为“农村地区”的照片,但是我们应该抛开这些偏见:一些发展中国家的“城市”不过是简陋的城镇而已。
 
所以当我们看到来自尼日利亚的Oyewolo Eyitayo的这幅获奖作品时,就更有理由感到兴奋。在你看到一半是土路的路上成排的太阳能板之前,你可能觉得这只是一张典型的平淡无奇的城市郊区的照片。

These winning photos capture the future of sustainable cities

The premise behind the Sustainable Cities photo competition was simple. We wanted to learn what people around the world “see” when they hear the words “sustainable cities.”
 
The submissions – and we at the Global Platform for Sustainable Cities received more than 90 entries from over 40 countries around the world – are very revealing.

What the photographers tried to communicate was a need: both the urgent need for infrastructure that leads to more resilient, sustainable cities, or a need to aspire to greener ideals of building sustainable communities for all.

There is no better day than today, World Cities Day, for us to share with you the 10 finalists – including 3 winners and an honorable mention for climate action – of the photo competition.

In the winning photo by Yanick Folly, one can practically feel the chaos of a city in Benin, the smell of exhaust fumes as cars crawl up alongside motorcycles and pedestrians down narrow alleyways.

Growing day by day, our world is always moving. Just see the big vibrant Benin market. #SustainableCities

The photo is also a reminder that cities are made of people. Any set of solutions for “sustainable cities” will have to make sense to a city’s inhabitants, who tread its streets daily.
 
In other photos, the aspiration is palpable. 

Many of the photographers are nationals of developing countries from all over the world. Yet quite a few of them shared photos of cities we regard as environmentally friendly: Singapore, Amsterdam, London, and Paris... We saw many photos of parks in developed countries, and heard the same message: These green spaces and pedestrian walkways are what we want in a city.

Many photos also reflect the vast difference between the aspirational city, and what most people actually live with.
 
We received photos of what many of us may categorize as rural areas, but we should reconsider these preconceptions: some “cities” in developing countries are little more than makeshift towns.
 
So, it is all the more reason why we are excited about this winning photo by Oyewolo Eyitayo from Nigeria. You might think this is an uneventful photograph of a typical urban suburb. Except that the half dirt roads are lined with solar panels.

Going solar is a simple & impactful #climateaction that can help combat climate change. #SustainableCities

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.
 

 


A housing policy that could almost pay for itself? Think retrofitting

The demand for decent, affordable – and safe – housing for growing urban populations is a nagging problem for financially strapped governments throughout the developing world. According to McKinsey & Co., a third of the world’s urban population – 1.6 billion people – will be hard pressed to obtain decent housing by 2025.
 
Housing policymakers, however, have undermined their capacity to increase the supply of good housing, quickly, by strapping themselves inside the myth that it is always better to build new homes rather than strengthening existing ones.
 
In Colombia, for example, 98% of all housing subsidies fund the acquisition of a new house or apartment; almost nothing goes to retrofitting existing homes to withstand the forces of nature and the tests of time.
 
While new construction may be a more attractive way to create schools, hospitals, and other public infrastructure, housing is a bigger, more pressing and complicated problem that may have a simpler solution: Bringing existing housing up to a decent standard of safety through retrofitting.
 
It’s not only a more efficient way to deploy limited government subsidies, but also a strategy to leverage these public funds with another private source in reach of governments: homeowners.

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.

Investing to make our cities more resilient to disasters and climate change

Joe Leitmann's picture

Urbanization comes at a price, especially in an era of climate change and increased risk of natural disasters.

Presently, the average annual loss from natural disasters in cities is estimated by the UN at over $250 billion. If cities fail to build their resilience to disasters, shocks, and ongoing stresses, this figure will rise to $314 billion by 2030, and 77 million more city dwellers will fall into poverty, according to a new World Bank/GFDRR report presented at COP22.

The good news is that we have a window of opportunity to make cities and the urban poor more resilient. Over 60% of the land projected to become urban by 2030 is yet to be developed. Additionally, cities will need to build nearly one billion new housing units by 2060 to house a growing urban population. Building climate-smart, disaster-resilient cities and housing is thus an immediate priority, especially in the developing world. 

To seize that opportunity, countries will need significant financing for infrastructure—over $4 trillion annually—and making this infrastructure low carbon and climate resilient will cost an additional $0.4 to $1.1 trillion, according to a CCFLA report.

Mobilizing private capital is the best bet for helping to close this financing gap.

Ahead of the next Habitat conference, the urban world we want

Sameh Wahba's picture


There is no better way to mark this year’s World Cities Day than reflecting on the adoption of the New Urban Agenda at the recent Habitat III conference in Quito. The agenda reaffirms the political commitment to sustainable urbanization and provides a framework to guide global urban development over the next 20 years, based on a shared vision of cities that are inclusive, safe, resilient and sustainable.

In an era of rapid urbanization and climate change, managing urban growth sustainably and building cities that work is indeed one of our most pressing development challenges.

Already, more than half of the global population — nearly 4 billion people — live in urban areas. Two decades from now, that number will grow to 5.5 billion — more than 60 percent of the world’s population. At the same time, the total built-up area of the world’s cities is expected to be double by 2030 what it is today, if not more.

Because urban-planning decisions lock cities in for generations, what policymakers decide in these two decades will make or break cities’ sustainable future for the rest of this century. With that in mind, one may ask: What will the world look like when Habitat IV takes place in 20 years?

I can imagine two opposite ends of the spectrum.

Implementing the New Urban Agenda needs financially strong cities

Ede Ijjasz-Vasquez's picture
Cities around the world face increasingly complex challenges such as rapid urbanization and climate change. Meanwhile, many cities facing the most pressing problems lack sufficient funding to meet local needs. This is especially the case for developing countries, where cities require significant infrastructure investment to provide basic services to growing populations and expanding urban areas.
 
How can cities access, leverage, and manage the fiscal and financial resources required to implement the New Urban Agenda and meet the growing needs of local populations?
 
To explore this issue, World Bank Senior Director Ede Ijjasz-Vasquez discussed the UN Habitat III policy paper on municipal finance and local fiscal systems with Mac McCarthy, President and CEO of the Lincoln Institute of Land Policy.
 

Toward a “New Urban Agenda”: Join the World Bank at Habitat III in Quito

Ede Ijjasz-Vasquez's picture
Cities are home to more than half of the world’s population, consume two-thirds of the world’s energy, and produce 70% of global greenhouse gas emissions. And this trend will only continue: by 2050, 66% of the 10 billion people living on earth will be urban dwellers.
 
As we mark World Habitat Day, these numbers remind us of a serious fact: while rapid urbanization brings tremendous opportunities for growth and prosperity, it has also posed unprecedented challenges to our cities—and the people who live in them.

Chief among these challenges is meeting fast-growing demand for infrastructure and basic services such as affordable housing and well-connected transport systems, as well as jobs—especially for the nearly one billion urban poor who are disproportionately affected by climate change and adverse socioeconomic conditions.

So, what will it take to build inclusive, resilient, productive, and livable cities?

What a Waste: Time to Pick It Up

Dan Hoornweg's picture

What a Waste publication coverAsk any city manager or mayor what their top priority is and you’re likely to get ‘solid waste’ as an answer. You would think in today’s age we would have solved the waste management challenge and moved on to the next slightly more glamorous municipal service. Not so; and more than ever cities now need to pick it up a notch on solid waste management.

Solid waste is still probably the world’s most pressing environmental challenge. In poorer countries, solid waste can use up to more than half of a city’s overall budget; around the world there are more solid waste workers than soldiers; and despite the more than $225 billion spent every year on solid waste, in many low income countries less than half the waste is collected in cities.
