Question

Ninety percent of the world’s population occupies only thirty percent of land area and the remaining is either sparsely populated or uninhabited.Illustrate using examples.

Answer 1

Answer:

A new global map released by the European Commission's Joint Research Centre and published in the World Bank’s World Development Report 2009, measures urbanisation from the new perspective of Travel Time to 8,500 Major Cities. The map fills an important gap in our understanding of economic, physical and even social connectivity.In the absence of agreement on the meaning of "urbanisation", the European Commission and the World Bank are proposing a new definition based on a unique mapping of “Accessibility” called the Agglomeration Index.

Key findings suggest that:

we passed the point at which more than half the world’s populations live in cities around the turn of the Millennium (2000) - much earlier than the 2007/8 estimate;

more than half of the world's population lives less than 1 hour from a major city, but the breakdown is 85% of the developed world and only 35% of the developing world;

95% of the world's population is concentrated on just 10% of the world's land; but

only 10% of the world's land area is classified as "remote" or more than 48 hours from a large city.

Leen Hordijk, Director of the Institute for Environment and Sustainability of the EC's Joint Research Centre, whose scientists prepared the new map, commented: "We have risen to the challenge of combining various information sources with the latest mapping technologies to produce a unique and timely product for the World Bank. Our map raises the question: For how much longer will remote ecosystems remain remote? Many are crucial to the healthy functioning of our planet."
