Vietnam unexploded ordnance, both bombs dropped by americans and land mines laid by both sides during the vietnam war, remain a big problem in central vietnam for children and adults alike. in response, crs has implemented a mine risk education program in quang tri province near the former khe sanh battlefield. this image shows the yard of a scrap metal merchant in tan hop. 80% of the steel comes from bombs, either exploded or unexploded. collecting and selling scarp metal has for long been an income for many poor people in the area

With such demands for Lake Victoria's Nile perch, the value of the fishery has risen considerably. Labour inflows into the fishery have increased along with growing demand. In 2004, there were 51,712, boats on the lake and 153,066 fishermen. All along the lakeshore, G®?boom townsG®ö have developed in response to the demands of fishing crews with money to spend from a dayG®ös fishing. These towns resemble shanties and have little in the way of services. Jinja, Uganda, East Africa

Orkney Islands Sept 2011 Wave and Tidal Power shoot - The Pelamis Wave Power machine in Orkney - alongside in Lyness - the machine is the P2 . The Pelamis absorbs the energy of ocean waves and converts it into electricity. The machine floats semi-submerged on the surface of the water and is made up of a number of cylindrical sections joined together by hinged joints. As waves pass down the length of the machine these sections flex relative to one another. The motion at each hinged joint is resisted by hydraulic cylinders which pump fluid into high pressure accumulators allowing electrical generation to be smooth and continuous. Control of the resistance applied by the hydraulic cylinders allows generation to be maximised when waves are small, and the machine response to be minimised in storms. All generation systems are sealed and dry inside the machines and power is transmitted to shore using standard subsea cables and equipment.
