Malaria in conflict



Conflict causes 30% of malaria deaths in Africa.
In 2007, 26 million people were driven from their homes by conflict. The effects of climate change - and conflict over limited resources like water, food and land - mean that every year, many people are likely to be forced from their homes. They often end up on land which has been abandoned because of the risk of malaria, or forced to live in over-crowded camps with poor health services, water, food and shelter.
In these situations, malaria is at its most deadly: frequently, more people die from the disease than the actual violence!
Insecticide-treated bed nets have a vital role to play in preventing malaria. But nets don't work so well if, like many displaced people, you have no bed, and no home. Malaria prevention, diagnosis and treatment require intensive, local information gathering which is often extremely difficult when people are still migrating or when violence is rife.

Recycle the sunshine

Interesting idea here to keep roads ice free in winter. Is this better than using salt on roads. The old question of how drivers of salt-spreading lorries get to work could soon be answered under government plans to recycle summer sunshine collected by Britain's roads and use it to keep them ice-free in winter. The Highways Agency plans to install pipes underneath a section of road to gather solar energy in summer and recirculate it in winter. Experts hope the scheme could be a way to treat the roads which are the first to freeze. Listen to the podcast here and see if you think it is useful? All I can see is roads now flooded when these pipes burst and water is wasted – am I just cynical? Full article here.

Hydrosphere revision


A little reminder of this site. We may get a chance to use it in class on Monday but time is tight before your NAB on Tuesday.

Don't forget to use the labels on the right here to help you revise. Look at the lithosphere one and Higher Coasts. Lots for the Hydrosphere and Atmosphere too. (for Int 2 as well!) We haven't finished the Biosphere yet so there isn't much chance of this one appearing. No more hints!

Geospy Game
Good one here for revision for S4 and S5 and a bit of fun for the rest of us. Have a go and see how good (or not!!!) you are.

Cities at Night


Amazing pics by NASA here. You can see more at this site. Look at the grid iron pattern of roads in Chicago and Denver.
