How the pace of technological progress is redrawing the political map
From power stations to factories, thermostats to smartphones, information to entertainment, the world is driven—and controlled—by digital technology. So it's no surprise that political and economic success, for businesses and nations, depends on how current they are with advances in technology. That's why Bhaskar Chakravorti and colleagues at the Fletcher School have created the Digital Evolution Index, a first-of-its-kind map of how, where and at what speed the use of digital technologies is spreading across the globe.
Global MPI 2015: Key findings
Oxford Poverty & Human Development Initiative
The Global Multidimensional Poverty Index (MPI) provides a range of resources. The Global MPI was updated in June 2015 and now covers 101 countries in total, which are home to 75 per cent of the world’s population, or 5.2 billion people. Of this proportion, 30 per cent of people (1.6 billion) are identified as multidimensionally poor. In June 2015, our analysis of global multidimensional poverty span a number of topics, such as destitution, regional and sub-national variations in poverty, the composition of poverty.

Attempts to understand population growth and the determinants of fertility date as far back as the late 1700s, when Thomas Malthus wrote ‘An Essay on the Principle of Population.’
Postulating that fertility decisions are influenced by women’s opportunity cost of time (Becker, 1960), choice over fertility has been incorporated in more recent times into growth models in order to understand the joint behavior of population and economic development throughout history. The large majority of existing analyses examine individual countries in a closed-economy setting. However, in an era of ever-increasing integration of world markets, the role of globalization in determining fertility can no longer be ignored.
When we think of urban expansion in the 21st century, we often think of ‘sprawl’, a term that calls to mind low-density, car-oriented suburban growth, perhaps made up of single-family homes. Past studies have suggested that historically, cities around the world are becoming less dense as they grow, which has prompted worries about the environmental impacts of excess land consumption and automobile dependency. A widely cited rule of thumb is that as the population of a city doubles, its built area triples. But our new study on urban expansion in East Asia has yielded some surprising findings that are making us rethink this assumption of declining urban densities everywhere.

And Why I’m Much Older than I Thought I was
When my kids became teenagers I began to feel old: I saw myself as fit, healthy and (relatively) young but they, clearly, didn’t and it began to be un-cool to be around them. I’m now in my 40s in a world that is growing older and older (the global life expectancy is now at 72) … so what’s the big deal?
I may be young in absolute terms but definitely not in relative ones! If you’re my age – 43 years – there are 5.1 billion (in a world of almost 7.3 billion) youngsters for whom that’s old. Seen otherwise, you are part of the world's 30 percent oldest people! It was a long time ago that I was in the middle of the global age distribution: today the “median human” is only 29 years old.
How mobile phones can save, not waste, energy
World Economic Forum
The mobile industry is experiencing explosive growth worldwide, fuelled by almost 7 billion subscribers and an ever-growing demand for data traffic. However, the energy efficiency of mobile networks remains extremely low. Both base stations and smartphones regularly waste 70% of the energy consumed as heat. The underlying power architecture used in mobile communications still relies on outdated technology developed during the 1930s. The impact of relying on such outdated technology is huge.
U.N. Predicts New Global Population Boom
MIT Technology Review
A new analysis suggests that the world’s population will keep rising through 2100, and not flatten around 2050 as has been widely assumed. Such an increase would have huge implications, but the prediction’s reliability is debatable, given that it does not take into account future hardships a large population would likely face. According to the new analysis by researchers at the United Nations and several academic institutions, there is an 80 percent chance that the world’s population, now 7.2 billion, won’t stop at nine billion in 2050, but will instead be between 9.6 billion and 12.3 billion by 2100.
We are living in a paradoxical time of population growth. In the media, there have been alarming reports asking how the world will be able to deal with a much larger population in years to come. The challenges are real, especially in Sub-Saharan Africa, whose population is expected to double by 2050 and possibly quadruple by 2100. At the same time, we have been experiencing the most rapid decline in global population growth ever.
But how can we reconcile those two facts: a rapid expansion of total population numbers with a fast slowdown of population growth? Here is an analogy from the world of cars: imagine you are driving on a German motorway, where speed limits are notoriously non-existent. You are cruising at 160km/h (100m/h) but soon you cross the border into France, where 130 km/h is the limit. You are still driving very fast, though substantially slower than before. Now you switch to a regional road, driving at 80km/h, and now you slow down further to 50 km/h as you enter into a town. Meanwhile, someone else is still driving at 160 km/h on that Autobahn.
The broad objective of the World Bank’s India Country Partnership Strategy Report (CPS) for the period 2013-2017 is to support poverty reduction and shared prosperity in India. The Report states that between 2005 and 2010, India’s share of global GDP increased from 1.8 to 2.7% and 53 million people were lifted out of poverty. But it also states that with population growth, it has proved difficult to reduce the absolute number of poor at a rapid pace and 400 million Indians still live in poverty. Each of the seven low income states (Bihar, Chhattisgarh, Jharkhand, Madhya Pradesh, Odisha, Rajasthan; Uttar Pradesh) and seven special category states (Assam, Himachal Pradesh, Manipur, Meghalaya, Mizoram, Sikkim, Uttrakhand) have poverty rates that are higher than that of the more advanced states. The low income states, where a large majority of the poorest 200 million Indians reside, are a priority for the World Bank Country Strategy funding during 2013-2017 (estimated to be $ 5 billion annually with 60 percent lending through direct financing of state projects of which half will go to low income and special category states).
India, both in the above mentioned and its advanced states (e.g. Punjab, Haryana, Kerala) is undergoing a massive rural- urban transformation- one of the largest in the 21st century. For the first time since independence, India has seen a greater absolute growth in urban population. The number of towns has increased from about 5000 in 2001 to 8,000 in 2011 and some 53 cities have a population exceeding one million. Today 30.1 percent of the population lives in urban areas and the share is expected to rise to 50% in the next 20 years (with urban India expected to generate 70% of its GDP by 2030). Though villages vastly outnumber towns in India (660,000 villages as per Census 2011), the construct of these villages is changing as the economy grows.
It struck me to find out that according to the UN’s official projections, populations of Tanzania and Uganda would exceed one billion people by 2100 (up from 45 and 33 million, respectively, in 2010) if total fertility rates in each of these countries remain constant at their 2010 levels (5.6 and 6.4 children per woman, respectively).
To be sure, this “constant fertility scenario” is not a likely one. For a number of reasons, fertility rates tend to fall as economies develop, and the process of demographic transition from high mortality and high fertility to low mortality and low fertility is already under way in both countries. Still, even under assumption that total fertility rates will gradually decline to about 2 children per woman (and there is no international migration), the UN estimates that there will be 171 million Ugandans and 316 million Tanzanians in 2100.
On Thursday I had the honor and privilege to make a presentation on issues of sustainable urbanization and urban poverty at a small summit organized by former U.S. Vice President Al Gore in New York City. Vice President Gore is writing a book about drivers of global change that will cover a range of topics including population and demographics, which was the focus of the meeting.
His team identified about 12 experts from a range of disciplines—a sociologist; demographer; geographer; researchers working on issues of family, aging, and gender; a writer; and an economist to explore patterns, trends, and current research. I was on a panel along with Saskia Sassen of Columbia University and David Owen of the New Yorker magazine. We all sat in a small room for 9 hours, presenting different perspectives on demographic change, each contributing from our own disciplines.
Measuring human progress is a messy, complicated effort. The Millennium Development Goals, or MDGs, are an effort to bring some standardization to that process, but the 8 globally agreed goals are viewed by some as a construct that handicaps the poorer countries into a race where they started a lap behind many other nations.
It's 10 years since the goals were agreed and 2010 has been designated the 'Year of the MDGs' by the UN and its partners. If all this helps feed hungry families, educate more kids and increase the distribution of antiretroviral drugs, I'm all for it. Good thing I feel that way, since I was working with the team that launched the Global Monitoring Report 2010: The MDGs After the Crisis on April 23.
Yet beyond the goals, targets and exhortations, as well as useful forecasts of extreme poverty rates in 2015, I wonder about the elephant in the room: population growth.
