Since geoengineering has gained a lot of attention from the media recently, it is interesting to look at how aerosols from industry have influenced climate.  Strange variations in temperature were experienced in the US from the years 1970-1990 where parts of the country, such as Arkansas and Missouri, were nearly 1C cooler than immediately surrounding regions and 0.7C cooler in parts of the Midwest and Mid-Atlantic.

At first this was thought to have occurred due to natural weather patterns, but recent research has shown that this ‘warming hole’ effect over parts of the US was actually due to the presence of sulphate aerosols in the atmosphere that originated mostly from coal-fired power plants.

The problem of brownfield land is universal.  Countries throughout the world have problems with contaminants  present in soil that prevent people from using the land.  Large demand exists to improve soil health and to regenerate brownfield land for present and future generations.  While brownfield land can clearly affect the physical health of people, plants and animals it may also affect people’s mental health or sense of well-being.

Land previously developed for industry or other uses may affect public health in a variety of different ways that does not appear well understood at this time.  IHRR’s research project ROBUST (Regenerating Brownfield Land Using Sustainable Technologies) at Durham University is investigating how to restore brownfield land sustainably, but is also researching how brownfield land affects the well-being of communities that live around it.  Recently, the project has begun its first public field trial testing a new technology for improving soil health that uses recycled minerals to improve the natural defences of the soil against contamination.

A report from The Climate and Development Knowledge Network looks at how to reduce economic vulnerability to disasters in low and middle-income countries throughout the world.  It provides some detailed recommendations for planning for disasters and reducing vulnerability along with conveying a comprehensive understanding of the current and future challenges for reducing economic losses to disasters in less developed countries.

While last year was the costliest on record for disasters this was due to the fact that some of the largest disasters of 2011 actually affected more developed countries the most, such as Japan (See 2011 worst year on record for economic losses due to earthquakes).  2011 revealed that developed countries are also vulnerable, but because their GDP can usually withstand losses from even large-scale disasters by comparison developing countries have more to lose especially in regards to climate change.  The macro-effects of disasters are ‘much more pronounced’ in lower-income countries, according to the report.  In many cases these losses come down to vulnerability — exposure to hazards and risks.  Read more

The ‘man-made hazard’ of war is universal in many developing countries, but it is one of many social and physical hazards they experience firsthand.  This article from IHRR’s archives looks specifically at research on resilience in young people in Afghanistan from two researchers: Catherine Panter-Brick and Mark Eggerman, whose work was based at Durham University.  They found that young people’s traumatic experiences in Afghanistan are not confined to war, but ‘range from armed insurgency to severe family level conflict’. Traumatic experiences caused by ‘everyday violence’ in Afghanistan lead to psychiatric disorders along with symptoms of post-traumatic stress.  Today, one in five school children in Afghanistan is likely to suffer from clinical mental health problems.

Everyday violence

In Afghanistan, young people are trapped within a landscape of violence that is not limited to war.  According to Eggerman, the kinds of violence young Afghans are exposed to include everything from ‘falling off a roof while flying a kite to witnessing a suicide bomb attack at a bus stop in Kabul’.  ‘There’s a spectrum of violence -– it’s not all about the war -– and it isn’t uniform’, he said.  The popular media’s of Afghanistan would have you believe that the entire country is a war zone.  But young people’s exposure to war-related violence depends on what part of Afghanistan they live in and 80% of young people interviewed by Panter-Brick and Eggerman had not left the country.  Older children had memories of devastating violence such as rockets falling during the Mujahideen civil war in the mid-1990s.  In Bamyan, they witnessed villages burn down and people severely beaten or shot by the Taliban.

But there were many other young people who had little exposure to political violence, although they had witnessed other acts of violence in their neighbourhood such as stabbings or severe public beatings.  They, along with other youth in Afghanistan, are focused on how to ‘make ends meet’ and live up to their family’s hopes and expectations.  Despite living in a country torn by war and other forms of violence, many young Afghans are just striving for socioeconomic survival.

I will be attending the 11th International & 2nd North American Symposium on Landslides in Banff, Canada and on the first day will be giving the opening keynote lecture on “Landslides and engineered slopes: Protecting society through improved understanding”.  In preparation for that, over the next month I will feature data from the Durham Fatal Landslides Database, which is the underpinning dataset for that presentation, without of course using any of the actual graphics from my talk or paper (I wouldn’t want to spoil the surprise for those who will be there!).

So, to start, this graph shows the cumulative number of people killed by landslides from May 2003 to May 2012:
