Eruptions in 2011 seemed to herald the arrival of a new island in the Canary Islands archipelago. Whislt this could create dangerous and disruptive ash clouds, it reminds us that there are many undersea eruptions on active margins around the world and that these could develop into new land.

The Tohoku earthquake and subsequent tsunami (11th of March 2001) was one of the largest ever recorded and caused serious damage and loss of life in Japan.

One of the most striking aspects of this incident was the way in which the Japanese people reacted. There was little in the way of looting and disorder, which can characterise the aftermath of disasters.
Bangladesh has a long history of suffering from the effects of cyclones, such as this one in 1991: http://en.wikipedia.org/wiki/1991_Bangladesh_cyclone. This article discusses Bangladesh’s vulnerability to cyclones and attempts to lessen that vulnerability: http://www.climate.org/PDF/Bangladesh.pdf.
Bangladesh is particularly vulnerable because so much of its land is low lying and as a nation, it has a relatively low level of economic development, meaning less money is available to spend on defences and recovery.
To try to help limit the loss of life, thereby promoting faster recovery from cyclones and other flooding events, shelters have been built on stilts, allowing the population to take refuge from the rising water.
In 2008 Bangladesh had a network of around 1500 shelters, capable of holding thousands of people each, and this due to be increased substantially following the devastation of Cyclone Nargis in 2008, which killed around 3300 people in Bangladesh: http://uk.reuters.com/article/idUKDHA105884._CH_.242020080108 & http://www.irinnews.org/Report.aspx?ReportId=76490.
The shelters are built on pillars to keep them above the water and usually perform a dual role as community centres. You can find lots of images of cyclone shelters here: http://www.archnet.org/library/sites/one-site.jsp?site_id=6452
Many cyclone shelters are built with aid donated from MEDCs and NGOs, such as these ones being built by the Swiss Agency for Development and Cooperation (SDC):
Kenya’s ongoing drought is having a severe effect on the environment, causing a number of changes as lakes dry up and plants and trees suffer. The drought combines with other man made pressures on the ecosystems and has a knock on effect on the people who rely on those environments to sustain them:
There are concerns that problems caused by the drought may ignite tribal violence:
One of the main ecosystems under threat is the Mau Forest. This report from the United Nations Environment Programme (UNEP) explains some of the treats facing the Mau forest; a list to which drought can be added:
