Farming can be precarious. This is especially true if you are poor and living in an area susceptible to climate shocks. In sub-Saharan Africa, with approximately 1 billion inhabitants, agriculture still accounts for roughly 64% of employment. Moreover, more than 95% of its arable land relies solely on rainfall, without the luxury of irrigation. As a result, climate shocks such as drought frequently cause crop loss and livestock death across the continent, sending large parts of the population into turmoil. A changing climate is expected to make the situation worse.
When I first heard about OpenStreetMap (OSM) – the so called Wikipedia of maps, built by volunteers around the world – I was skeptical of its ability to scale, usability in decision making, and ultimate longevity among new ideas conceived in the digital age. Years later, having working on many disaster risk management initiatives across the globe, I can say that I am a passionate advocate for the power of this community. And I continue to be struck by the power of one small initiative like OSM that brings together people across cultures and countries to save lives. It is more than a technology or a dataset, it’s a global community of individuals committed to making a difference.
Sub-Saharan Africa is making significant economic and development strides. Yet, natural disasters, combined with the effects of climate change, rapid urbanization, and conflict situations are threatening these gains, keeping vulnerable and poor communities in a chronic cycle of poverty:
- 425 million people who live in Africa’s drylands are highly exposed to climate shocks, and this number is set to grow by at least 50% by 2030. We cannot fully quantify the human cost, but Kenya alone suffered losses of $12 billion in the 2008 to 2011 drought. Official development assistance (ODA) in humanitarian aid to the Horn of Africa after the 2011 drought was $4 billion, 10% of all aid to Africa.
- Africa’s coastal cities are engines of growth, but are highly vulnerable to flooding and sea-level rise. In the last three years, major floods have hit cities such as Maputo, Dakar, Lagos and Douala. Like droughts, floods won’t go away. Along with periods of extreme heat, strong winds and coastal storms, they are likely to become more frequent.
- Ebola Virus Disease outbreak, from March 2014, was the most widespread, and reached epidemic proportions. The poor bore the brunt, lost their jobs and incomes, had difficulty accessing medical services and suffered psycho-social trauma. On a macro-level, Guinea, Liberia and Sierra Leone are estimated to lose over $1.6 billion in forgone economic growth in 2015.
- Conflicts and disasters often reinforce each other to worsen negative development impacts and increase human suffering. From 2005 to2009, more than 50% of people affected by disasters lived in fragile and conflict-affected states (globally). Fourteen out of the 20 most conflict-affected states are in Africa.
Imagine yourself in the last century, walking down one of the streets of a large Central Asian city. You are surrounded by architecture dominated by the Soviet style, with common building types stretching across the blocks. As you walk the streets, suddenly, the ground under your feet starts wobbling and everything around you starts shaking. Buildings, trees, and cars start to shake and you cannot walk any more. Instantly, many structures start to collapse and there is dust and screams everywhere. There is chaos and desperation. An earthquake of magnitude 7+ has hit the city. This story, a true story, has happened several times in each of the Central Asian countries in the last century.
Halfway across the globe, in the South Asia region, another ice-snow regime is under threat, and although less scrutinized by the media, has the potential to trigger catastrophic economic and social consequences.
The Hindu Kush-Himalayan region is widely called the third pole and in this ice-snow regime of the third pole are the origins of three mighty rivers – Ganges, Brahmaputra and the Indus that indirectly support over 700 million people across South Asia.
The ice and snow regime is among the most fragile earth systems that will be impacted massively by a changing climate and the melting and disappearing of the three poles (the Antarctic, Arctic and high-altitude mountain glaciers) will in turn exacerbate sea level rise and extreme weather patterns.
In the second in this series of blogs, we highlighted the need to introduce adaptive delta management to the Bangladesh delta. The reason—to manage the long-term risks facing the Delta by investing in adaptive and flexible, short-term activities. The most striking need for this approach is climate change, which unchecked will undermine Bangladesh’s many development gains.
Cities are a puzzle for some and inspiration for others. As engines of economic growth, they are also hubs of rapid urbanization, a rising middle class, and a growing population. These three mega-trends drive global environmental degradation yet are only part of the important challenge facing cities today.
While consuming over two-thirds of global energy supply and emitting 70% of all carbon dioxide, cities are also uniquely vulnerable to climate change. Fourteen of the world’s 19 largest cities are located in port areas. With sea level rise and increased storm activity, these areas are likely to face coastal flooding, damage to infrastructure, and compromised water and food security. Under these conditions, meeting urban population’s growing production and consumption needs for food, energy, water, and infrastructure will overload rural and urban ecosystems.
To tackle these issues, the Global Environment Facility (GEF), in collaboration with the World Bank Group (WBG), launched the Sustainable Cities Program to engage 23 cities in 11 developing countries. Hailing from one of such countries, two urban development specialists working on each side of the Program explain why making cities more sustainable appeals to them.

As world leaders come together at the UN General Assembly to adopt new sustainable development goals, climate change activists gear up for Climate Week in New York City and the Pope brings his message to the United Nations, a shared vision of our future is coming into clear focus.
If we are to eradicate poverty, we need to tackle climate change. And since 2008, the $8.1 billion Climate Investment Funds (CIF) has been showing it is possible for countries to pursue sustainable development in a way that does just that.
Lorne Turner served as Manager of Performance Management for the City of Toronto.
Lorne was a city practitioner, tasked with the professional, meaningful and honest monitoring of the progress of Toronto, alone and alongside other world cities. He firmly believed that all cities – in Ontario, Canada and around the world - succeed when working together, and that measuring this progress is absolutely critical. Lorne was a ‘details-guy’ who knew how the small brushstrokes blended together to paint a community, a country, and later in his life, he helped demonstrate how they could define urban life around the planet.
Lorne passed away last week, after a long battle with cancer. Lorne was in his role for almost 30 years (including Budget Director, North York, 1988-97).
Lorne’s passing is particularly poignant for city workers. Lorne was quiet and modest; he fit his professional accountant stereotype well. He was also highly effective. Last year, the global city indicator standard was published (ISO 37120). This standard is important for all cities and is anchored to Lorne’s perseverance, commitment and his ability to keep the City of Toronto actively engaged for the more than ten years it took to develop the idea. The idea and the standard owes much of its existence to Lorne.
