Fully funded PhD scholarship at the Transport Studies Unit at Oxford

Heads up: The Transport Studies Unit (TSU) at the School of Geography and the Environment of the University of Oxford will have one fully funded, three-year Doctor of Philosophy (DPhil/PhD) scholarship available for a citizen from a country in Africa, South and South-East Asia, Latin America and the Caribbean or small island states in the Pacific or Indian Ocean. More details here.

I'm certainly biased here, but this is a great opportunity to study along brilliant researchers in an incredibly vibrant department at one of the top universities in the world. This is a competitive scholarship, sure, but this should not stop you from applying. You only need one spot. ;)

How many people have ever lived on Earth?

Have a guess. I can only say I was wrong by a lot :) Now select this back box to see how close your guess was. 109 billion  There is a nice article by PRB on this question and how one arrived at this estimate. HT Sergei Soares.

World population projected to reach 10.9 billion by 2100

The UN Population Division published this year its report World Population Prospects: The 2019 Revision with lots of goodies, including the latest world population projections. Here are the ten key findings of the report:
  1. The world’s population continues to increase, but growth rates vary greatly across regions
  2. Nine countries will make up more than half the projected population growth between now and 2050
  3. Rapid population growth presents challenges for sustainable development
  4. In some countries, growth of the working-age population is creating opportunities for economic growth
  5. Globally, women are having fewer babies, but fertility rates remain high in some parts of the world
  6. People are living longer, but those in the poorest countries still live 7 years less than the global average
  7. The world’s population is growing older, with persons over age 65 being the fastest-growing age group 
  8. Falling proportions of working-age people are putting pressure on social protection systems
  9. A growing number of countries are experiencing a reduction in population size
  10. Migration has become a major component of population change in some countries

A neat visualization of population growth by region based on UN Population Division (2019) medium variant scenario projections. This chart was put together by Our World in Data, who have plenty more material on this and other topics.

geobr: data updates

Some of you are already familiar with geobr, an R package that we developed in Ipea to facilitate downloading official spatial data sets of Brazil (a quick intro to geobr here). The stable version 1.0 was published on CRAN a couple of months ago. Since then, we have added some new data sets.

geobr now brings official spatial data of natural biomesindigenous lands of all ethnicities in Brazil according to stage of demarcation, and risk areas prone to landslides and floods in Brazil. These data sets are currently only available in the development version of the package, wich can be installed with devtools::install_github("ipeaGIT/geobr".

Public investment and state sponsored speculation

Great piece with a critical take and neat data analysis of how the New York’s High Line project affected real state property prices. It was written by The Dark Matter Labs & Centre for Spatial Technologies teams, who use this case to draw some interesting reflections on public investment  and state sponsored speculation.
