Renewable energy is defined as ‘energy from a source that is not depleted’. Main sources include biomass, hydropower, wind, biofuels, solar, heat pumps, biogas, geothermal, and marine (such as tidal power). Data by the International Energy Agency sees the share of renewable energy in global power generation at 22 per cent in 2013, with an estimated increase to 26 per cent by 2020 as a result of supportive policies by a large number of governments.
Tropical cyclonic systems are generally referred to as tropical storms. They are better known by their regional names, such as hurricanes in the Caribbean and North America, or typhoons in parts of Asia. They form near the equator over larger bodies of warm waters that evaporate from the ocean surface and fuel these emerging storm systems. Their strong winds and heavy rainfalls frequently become part of our news as they often put large numbers of human livelihoods at risk.
Recent studies show that the number of tropical cyclones (as well as tropical cyclone intensity) over the past decades has increased. Tracks of tropical storms collected over a longer period can indicate where such storms occur most frequently. The records used in this issue’s visualisation covers data from 1945 to 2008.
Wine is produced commercially in more than 70 countries, three of which account for almost half of the world’s production: France, Italy and Spain. What else does a closer look at the world of wine tell us?
The geography of wine – the product obtained exclusively from the total or partial fermentation of fresh grapes – can be viewed both from the perspective of producers or consumers. Continue reading
Nuclear power contributes only a small share to the global energy production. According to the World Energy Statistics 2015 published by the International Energy Agency (IEA) nuclear power accounts for 4.8% of the total primary energy supply worldwide, far behind oil (31.1%), coal (28.9%), natural gas (21.4%) and even behind biofuels and waste (10.2%).
Of the producers of nuclear power, the United States are by far the largest with 33.2% of the world’s total, followed by France (17.1%) and Russia (7.0%). The United Kingdom’s production accounts for 2.9%. In contrast, France generates the largest share of its domestic electricity generation from nuclear power (74.4%). It is followed by Sweden (43.4%), Ukraine (43.0%) and South Korea (25.8%), while the United Kingdom comes fifth with 19.2%.
Public spending cuts have been an important part of the political debate in Britain in recent years. In an article for the “In Focus” section of Political Insight (April 2016, Volume 7, Issue 1) Danny Dorling and I plotted the distribution of funding for the arts and universities in England.
The United Kingdom, and especially England, has become geographically extremely unequal. This inequality is not only seen in growing economic disparities within the population, but also becomes increasing visible across all parts of public life, such as science and education, as well as the arts. A report on arts funding in 2013, highlighted just how concentrated such funding was within London compared to the rest of the country. This represents the continuation of a now long-established trend.
Poverty and global development are not only on the agenda at the World Economic Forum in Davos. But despite positive trends being observed in the aftermath of the Millennium Development Goals poverty still persists.
As a successor to the Millennium Development Goals (MDG), the United Nations announced a set of 17 new Sustainable Development Goals (SDG) relating to international development. Still on top of the agenda remains the issue of poverty. Here the new goal is to ‘end poverty in all its forms everywhere’ by 2030, meaning to ‘eradicate extreme poverty for all people everywhere, currently measured as people living on less than $1.90 a day’ and to ‘reduce at least by half the proportion of men, women and children of all ages living in poverty in all its dimensions according to national definitions’.
There are trends in past decades that indicate major improvements in tackling the problem of global poverty. In relative terms, the original MDG goal of halving extreme poverty between 1990 and 2015 has been met. In developing regions, people in extreme poverty now make up 14 per cent of the population there, while most recent figures and estimates suggest that still over two billion people globally live on less than $2 a day, a measure used to measure ‘moderate’ poverty. This figure is also used as a base for the main cartogram below. The map modifies the size of each country according to the total number of people there who live on up to $2 a day according to the most recent available estimates. In addition, the colour shading uses information from the 2015 Multidimensional Poverty Index (MPI) to highlight the percentage of the population that is multi-dimensionally poor.
