In Kerala, India a company called BIOTECH is running a food-waste-to-energy enterprise:
"BIOTECH has succeeded in tackling the problem of the dumping of food waste in the streets of Kerala through the installation of biogas plants that use the food waste to produce gas for cooking and, in some cases, electricity for lighting; the residue serves as a fertiliser. To date BIOTECH has built and installed an impressive 12,000 domestic plants (160 of which also use human waste from latrines to avoid contamination of ground water), 220 institutional plants and 17 municipal plants that use waste from markets to power generators. The disposal of food waste and the production of clean energy are not the only benefits of BIOTECH's scheme. The plants also replace the equivalent of about 3.7 tonnes/day of LPG and diesel which in turn results in the saving of about 3,700 tonnes/year of CO2, with further savings from the reduction in methane production as a result of the uncontrolled decomposition of waste, and from the transport of LPG."
Farmer Jose Elanjhimattam demonstrates how he converts dung from his cows into biogas.

"Nomads in Ethiopia Receive Education on the Move"
A video about hygiene education taught from the backs of camels and in the shade of trees in Ethiopia:
"Thousands of charities and non-governmental agencies do development work in Africa, spending billions of dollars trying to make the continent a better place. There is a vigorous international debate over such assistance. While some projects claim success that provides new opportunities, critics contend that development money often does little good and can make matters worse. On a visit to Ethiopia's remote Afar region, correspondent Peter Heinlein found a development group that found success where others failed by 'following the clouds'."
