the Land Matrix

One aspect of global inequality has to do with land-- who has access and can use it. As inequality widens and with growing concerns about population growth, some countries are increasingly buying, renting, or otherwise taking some form of ownership over the land of other countries. Have a look at this website to see which countries are doing what to what countries. Why do you think this is so important?

Historical World Population Growth & Demographic Transition

Importance of Age Pyramids

Age or Population Pyramids

From Wikipedia:

A population pyramid, also called an age pyramid or age picture diagram, is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing.[1] It is also used in ecology to determine the overall age distribution of a population; an indication of the reproductive capabilities and likelihood of the continuation of a species. (from Wikipedia)

the importance of geography, population growth - great post from Benjamin Hennig

A great post by Benjamin Hennig on population growth, geography, and sustainability. Hennig writes

Geography matters because where populations increase and where they decline is highly relevant for finding solutions that provide a better future for all of humanity. While we are already producing enough food for 10 billion people, as shown in a study published in Nature, we do not manage to distribute this fairly so that hunger is a persisting problem. A population of 9, 10 or even 11 billion does not have to be a disaster if humanity makes more effort to minimise its environmental impact while providing a sustainable basis for how many people there are in the world.
