As concerns about global food security are on the rise, there are many questions as to how the world will face growing demands for a sustainable food supply. While poverty and food distribution seem to underlie many of the challenges regarding food security, biotechnology in the form of genetically modified seeds could continue to play an increasing role in how food is grown and traded in both developed and less developed countries.
Does patenting seeds create new risks to food security or provide a way of securing the world food supply through centralisation? Are we simply looking at a new way of meeting the demands placed upon agriculture or a new way for chemical corporations such as Monsanto, Dupont, Dow Chemical and others to place new demands on society? Most importantly, where does this leave farmers and the communities they support?
Durham postgraduate researcher Hanna Ruszczyk has been awarded a PhD fellowship for her research on community resilience and earthquakes.
Hanna’s postgraduate award has been made possible thanks to a generous gift from a Durham alumnus. Hanna’s research, will investigate the role of resilience in disaster risk reduction. She will study how resilience strategies can be operationalised within urban communities vulnerable to seismic hazards in Nepal and Bihar, India. Her PhD programme is based in the Department of Geography, linked to IHRR and is supervised by Dr Katie Oven and Dr Colin MacFarlane.
For her PhD, Ruszczyk is making a comparative analysis between Nepal and Bihar, which will investigate how to build individual and community level capacity for resilience. Both have their own particular strengths and weaknesses when it comes to adapting and building resilience to natural hazards. ‘I’m looking at how they can learn from each other’, said Ruszczyk. ‘There is a clear social element of resilience, but what are the most important components of resilience to be aware of?’, she asks.

A little over a month ago I gave a talk at the Vajont 2013 conference on the topic of landslides and large dams. At the time I committed to making the Powerpoint file available online, so here it is:
The file is located on slideshare – you should be able to download the powerpoint file from there. The piece is also written up in an article for the conference paper – reference below. The paper can be accessed, for free, from the conference website. The other talks and papers can also be accessed from the conference website.
In this work I looked at the Durham Fatal Landslide Database to try to understand fatality-inducing landslides associated with large dams over the last decade. My analysis of the dataset suggested that in total there were exactly 500 deaths in 37 landslide events in the ten years between 2003 and 2012. Surprisingly, with one exception these were not landslides associated with the collapse of reservoir flanks (although interesting there was an event of this type in China earlier this year). Most of the landslides were either failures at the construction sites of large dams or at the sites of workers camps. Read the rest of this entry »
Typhoon Haiyan has caused severe devastation in the Philippines leaving an unknown number of people dead. While early estimates have been made, the number of fatalities is likely to rise. Survivors are without food, clean drinking water or shelter. Immediate global support, especially funding, is needed for providing assistance to affected communities.
Durham University Professor and IHRR Co-Director Lena Dominelli, a sociologist and international social worker in disaster resilience, is in touch with survivors of the typhoon disaster in the Philippines who she says are desperately in need of humanitarian aid.
“It’s absolutely essential that money is sent to people for buying food, clean drinking water, and medical supplies for those who have critical conditions. A lot of the areas destroyed by the typhoon have no power supplies and no communications except by satellite phone,” said Dominelli. Read the rest of this entry »
When I was studying Physics at school, we were shown the famous regelation experiment in which a wire is placed over a block of ice and a weight is attached to each end. Though time the pressure on the wire causes melting of the ice, and the wire slowly cuts its way through the block, and eventually the weights and wire fall to the ground. As the wire passes through, the water refreezes, such that the wire appears to pass magically through the ice.
There are various versions of this experiment on YouTube, of which this is about the best:
The interesting part of this experiment starts at about 1:22 and ends at 1:40 (in the speeded up sequence). Of course when the wire finally cuts through the ice the weights collapse to the floor with a great crash – the very last moments before this are shown below: Read the rest of this entry »
