not always so easy because the past apply is quite erotic but then again engineers at the university of nigeria are working to alleviate the problem let's go see what they're doing. nigeria's national power supply is notoriously unreliable. there are frequent outages so many people depend on generators. engineers at the university of nigeria looking for solutions. they've constructed a system that converts organic waste into gas. materials such as corn husks or wood chips of lead into the reactor what we. call. a chemical process produces gas which in turn powers a generator that produces electricity. we've never. seen. one that we've been able to deny. that we've been there would have been lying through which we know of their environment. this power plant cost about $25000.00 euros to build. because as the energy needs for the department of engineering but researchers are working on a larger version. it would take 12 of those larger versions to supply energy for the whole campus that would save the university a lot of money and put waste to good use to the people and the environment. and how a

university. our first panelist is professor tomori of biology from university ibadan nigeria and former president of nigerian scientists, rick santos, senior adviser to ima world health, panelist three steve davis and four, ambassador william garvelink, international medical corps and former u.s. ambassador to the drc. david, i will turn it over to you. >> thank you very much. the panel wanted to make sure that i thanked you dean parker and director natsios for having us here with focus on emergencies and we're all looking forward to sharing some thoughts about some of the opportunities in particular of working with and host countries at risk or experiencing risks in the way that we've heard discussed already this morning. gentlemen, on this opening round, as you respond to a starter question from me, if you would please also take a moment to remind the audience of your organization, its mission and its role, in either the current emergency and the democratic republic of congo or another one on which you believe we ought to focus on the course of our discussion. feel free to answer the question i

nigeria. scientists at the university of cambridge, have unveiled plans for a uk research centre to develop newitiative is the first of its kind in the world and could lead to dramatic reductions in carbon emissions. 0ur science correspondent, pallab ghosh reports. a scorched earth, where people are poorer and have less food because of severe droughts. there'll be more flooding and all the coral has gone. that's what we are headed for, unless we do more to cut emissions of carbon dioxide. scientists at cambridge university fear that reducing co2 emissions on its own won't be enough. the man who's led efforts at the heart of government to combat climate change for 20 years is helping to set up a new research centre to develop ways of repairing the damage that's already been done. we are looking for processes that are scalable, by which i mean processes that can take out billions of tonnes of greenhouse gases each year. with trillions of tonnes of ice gone from both the earth's poles, the new centre will look at ways of refreezing them. one idea is to have boats spray sea water into the clouds ab
