MUMBAI: In the seventh episode of the series, Adam Shaw travels to New York City to meet Professor Jeffrey Sachs, director of the Earth Institute and a Special Advisor on Poverty and Hunger to the United Nations, to explore the issue of global food security.

By 2050 the global population is expected to rise to over nine billion, with food production having to increase by 70 per cent in order to provide everyone on the planet with acceptable levels of nutrition. Adam and Professor Jeffrey Sachs discuss new ways in which technology can be used to ensure a smarter, more productive approach to farming.

Professor Sachs said: ?The global food supply is under stress. We need a dramatic reorientation towards sustainable technologies in food. The planet is very crowded. This is putting tremendous stresses on the planet in many ways. The huge question for the world is how can a globally interconnected society of seven billion people ? that soon will be eight, could be nine or ten during this century ? live together [and] enjoy prosperity that is properly shared.?

In the UK, Adam visits Surrey Satellite Technology, a company that uses advanced technology to build and operate affordable satellites. On-board cameras are being used to give farmers unprecedented levels of information on the health of their crops (detail that would be invisible from the ground) allowing efficient targeting of soil nutrients and irrigation to increase crop yields.

Surrey Satellites is also now working with Nigeria?s National Space Research and Development Agency (NASDRA) to help government agencies reduce the impact of possible natural disasters.

Later, Adam heads to North Wyke Farm in Devon which houses a unique outdoor laboratory designed to discover new ways of farming which are sustainable, productive and minimise environmental impact.

Finally, presenter James Chau travels to China?s largest city, Shanghai, where the Chinese Government has set itself the target of growing 95% of the city?s vegetables in the local area.They?ve got some way to go but have made a start by controlling production in the area, protecting cultivated land and building a ring of farms that account for a third of Shanghai?s urban area.

MUMBAI: In the sixth episode of the series, Adam Shaw meets Jimmy Wales, founder of online encyclopaedia Wikipedia to find out how the site has grown from small beginnings to become one of the world?s most visited online information resources.

Adam and Jimmy Wales discussthe increasing democratisation of the web. Technological advances such as cheaper smart phones and mobile optimised websites mean millions more people in developing economies have access to the internet, which is causing a radical shift in the previously westernised voice of the World Wide Web.

In India, Horizon?s Reporter Rajini Vaidyanathan meets the founder of Delhi-based technology for social development company, ZMQ Software Solutions, to find out how their mobile phone apps and educational games are helping to empower the poorest in society.

Rajini also meets a group of women who have been able to start their own small businesses using apps, which provide access to microloans and teach basic economic skills.

In part two Adam and Jimmy Wales discuss the growing global trend of Open Data and the idea that all information collected by governments should be made available to their citizens in an easy to read format to generate new educational opportunities and stimulate commercial enterprise.

Adam then travels to San Francisco to find out how the city?s municipal government has been pioneering the Open Data movement, making thousands of statistics and data sets from its daily operations freely available to the public.

Finally Adam meets the city?s chief innovation officer Jay Nath to find out how information software designers are turning information as diverse as public transport timetables, crime mapping and food hygiene inspections, into lifestyle apps, which aim to improve the experience of living in the city. He also meets one resident who has done just that by creating her own app targeted at helping families with young children.

Mumbai: Initial data released by TAM following?s India?s recent digitalisation shows that BBC World News has reinforced its leadership position as India?s top English language international news channel.

The TAM data also shows that, following digitalisation, BBC World News has substantially increased its audience in Delhi, Mumbai, Kolkata and Chennai. The channel?s weekly absolute share has increased by 109% and its absolute reach has increased by 34% in those markets while English language domestic news channels experienced audience erosion.

In separate data, released last Friday, IpsosPAX figures show the BBC continuing to build cross platform strength. The most recent IpsosPAX survey (Q4 2011 to Q3 2012) underlines the BBC?s television and digital lead in key demographics such as India?s high income households, C suites and international travelers.

The Ipsos PAX study surveys international and local media consumption and product consumption among affluent adults and business professionals in the Indian cities of Mumbai, New Delhi and Bangalore.

Jim Egan, Chief Operating Officer, BBC Global News Ltd, says: ?It?s been a year of rapid evolution for the television industry in India and also for BBC World News. Just weeks ago, we launched the channel with a fully produced HD signal and a refreshed line-up of programmes and presenters from new studios at Broadcasting House.

Given the growth the channel has already experienced post-digitalisation in India; we?re looking forward to building on that success in the months and years ahead.?

Mumbai: Broadcasting on 17th November and 18th November 2012 In the seventeenth episode of the Horizons series, presenters Adam Shaw and Saima Mohsin take a closer look at a new generation of energy crops in Brazil and the United States, where companies are using plant biomass and single celled plants or algae to produce fuel.

At some point our traditional sources of power such as coal and oil will run out and there is an increasing need to find alternatives. Turning plants into power is one option. Currently more than 80 million hectares of land are planted for bio-fuels including sugarcane, corn, palm oil and beets.

By 2050, if we?re to power the globe?s projected fleet of vehicles by biofuels, we would need to deploy more than 650 million hectares of arable land. That?s an area nearly the size of Australia.

So can biofuels be grown more efficiently?

First, Adam Shaw heads for the Cane Technology Centre in Piracicaba in Southern Brazil, an area forming part of the largest sugarcane growing region in the country. They?re now breaking down sugarcane waste or bagasse to produce bioethanol. The challenge is to digest cellulose ? the tough cell walls of green plants - and turn it into useful sugars. It is a difficult, complex process both mechanically and chemically and they?re looking to scale up production in a few years.

Jaime Finguerut, Industrial Strategic Development, Cane Technology said:?We could grow not just horizontally but vertically, extracting more ethanol from the same sugarcane, like petroleum going deeper looking for oil, we are going deeper into the structure seeing where we can get more sugar."

Saima Mohsintravels to San Francisco in the United States to look at so-called ?third generation bio-fuels?, which are made from single-celled plants or algae. Solazyme is working with Chevron, Honeywell and United Airlines to develop biofuels using genetically modified algae that feed off plant sugars in tanks. Bringing the cost down, while ramping up production is going to be crucial.

The company has been awarded a contract by the U.S. Department of Defence to supply 550 thousand litres of bio-diesel made from genetically modified algae and opened its first commercial facility, with funding from the U-S Department of Energy.

Harrison Dillon, Chief Technology Officer, Solazyme said:?The way the process works is these algae will eat plant material, like sugarcane or waste biomass and rapidly and efficiently convert that plant material directly into crude oil.

And once we have that crude oil we can then turn it into diesel fuel, jet fuel, or any oil-based product."

The Horizons series, sponsored by DuPont, airs weekly on BBC World News on Saturday 7.00am & 2.00pm and Sunday 8.00pm and 1.00am.

MUMBAI: International news channels BBC World and CNN International continue to grow in the country. CNN International reaches more viewers globally than any other international news channel, with findings from both the latest Pan-Asia Pacific Cross-Media survey (PAX) and Europe?s Media and Marketing Survey (EMS) reinforcing the network?s undisputed leadership position. The Pax survey reveals that no international English news channel reaches more Indian viewers on a monthly basis than CNN International. In India, CNN International is more of a daily habit than BBC World News among Business Decision Makers and Top Management.

The latest Pax findings for the first to the fourth quarter of 2011 show that CNN International continues to be a leader in the Asia Pacific region among international news and business channels across all metrics:

Meanwhile as far as one of its arch rivals BBC World News is concerned an Ipsos Pax survey showed that in India, it is the top international English news channel and the news destination of both the young and upwardly mobile mid-level corporate managers. BBC World News was also shown to be the most watched international news channel for mid-level income earners, women, tech enthusiasts and those under the age of 30. The channel is also the most watched news channel amongst key audiences such as potential car buyers, international travellers and consumer durable owners.

The latest Pax survey also demonstrated the power of BBC?s integrated reach across its TV and digital platforms. BBC combined platforms reach out to more young people, mid management execs, women, potential car buyers and international fliers as compared to key competitors.

BBC World News commercial director Colin Lawrence said, ?BBC World News and BBC.com are strongly demonstrating impact to Indian audiences?not only top management but also those with their careers on the rise. Our platforms deliver a targeted route to these discerning viewers and it?s more and more clear that our style of impartial international news and business coverage is increasingly relevant to viewers and advertisers across the country.?

The latest Pax findings also highlighted CNN International?s ability to reach business leaders and travelers in the Asia Pacific region.

- More business travelers watch CNN International in a single week than BBC World News in a month

- Leisure travelers also have a stronger connection with CNN International, with 49% more leisure travelers watching CNN International each week than the next placed news/business channel - CNN International enjoys a clear audience advantage among key business targets, such as Business Decision Makers and Top Management (57% and 42% reach advantage respectively) over the next placed news/business channel CNN International executive VP Tony Maddox said, ?What we are seeing is that there continues to be a strong appetite for global news, and that people throughout the world are turning to CNN for that news ? and in great numbers. People want a depth of analysis and a genuine breadth of coverage, and we provided that throughout 2011 wherever the big stories were breaking, and continue to do so in 2012. Add in our commitment to global business news and our excellent sports and cultural programming and there is a clear, compelling proposition for viewers.?

CNN in Asia Pacific VP, News ad sales William Hsu said, ?Once again, CNN?s ability to reach this highly-desirable, upscale target audience is unmatched. There is simply no better platform for advertisers across the Asia Pacific region, and the caliber of our clients is testament to our ongoing best-in-class performance here and around the world.?

In addition to CNN International?s on-air positioning, the PAX survey shows that CNN International?s leadership also extends to its digital platforms.

- Each month CNN.com/CNNMoney.com reaches 51 per cent more users online than BBC.com, and more than twice as many (+113 per cent) Top Management

- 95 per cent more business decision Makers visit CNN.com/CNNMoney.com than the next largest international media site - CNN International?s multi-platform reach in Asia Pacific is unrivalled among news/business brands, with the network?s weekly combined TV and digital audiences 54% greater than that of the next largest news/business provider

In Europe, CNN International achieved a record score in the latest EMS 2012 research, achieving the best ever score for any news network in monthly reach, with 36.9 per cent (18 million viewers). Overall, CNN International is also the number one multi-platform news provider in Europe, with 47 per cent monthly combined reach across TV, mobile, and online.

Mumbai: In the second episode of the series, Horizons presenters Adam Shaw and Saima Mohsin travel to the United States and the United Kingdom to explore the burgeoning science of nanotechnology. The technology enables scientists to arrange atoms and molecules to create new materials and devices which could have the potential to change our world through applications in medicine, electronics, biomaterials and energy production.

Horizons co-presenter Saima Mohsin begins at Rice University in Houston, Texas where she meets Professor James Tour, one of the world?s leading pioneers of nanotechnology. Saima explores technology that enables engineers to manipulate substances at the nano-scale and advances which could see the development of much faster and even flexible electronics, such as the production of a carbon based ink which can be printed onto flexible films to create electronic circuits powered by radio waves. Saima also learns about what?s being called the next super material-- Graphene, one of the strongest and most conductive materials ever found.

Professor James Tour said: "Graphene is a single sheet of graphite only one atom thick. This is an amazing material. It?s made up of all carbon and the carbon bond is one of the strongest bonds in the universe. The other thing about Graphene that is really quite amazing is its electronic properties. You can move information through Graphene at a very high rate, probably one hundred times faster than we can compute today. It has materials applications, electronics applications. The applications go into entirely new types of devices we haven?t even begun to envision yet. It?s huge."

Back in the UK, award-winning business journalist Adam Shaw visits Cambridge to learn about two companies using nanotechnology in applications which could save lives. At Endomagnetics, Adam finds out how nanotechnology research is already offering an alternative way to detect breast cancer, using a new technology called Sentimag which uses magnetic tracers that are safer and more widely available than the radioactive tracers currently in use. He sees the technique being trialed by specialists at Guys Hospital in London and explores whether it could ultimately revolutionize the treatment of cancer globally.

Mr Michael Douek, Guys Hospital, London explained: "I have been working on breast magnetic resonance imaging for many years. It?s the first time we can use a hand held device to guide us to something we can actually see on magnetic resonance imaging. It does assist the surgeon in finding the lymph gland to drain a breast tumour. The technology is novel and has many exciting applications in breast cancer treatment."

Finally Adam visits Owlstone Nanotech, another Cambridge-based company which is leading the field in chemical detection systems. Using the latest nanofabrication techniques, the organization has created a device that can be programmed to detect a wide range of airborne chemical agents in extremely small quantities. This technology could have a huge range of applications including, as Adam discovers, the development of a breathalyzer that would allow doctors to detect the presence of individual chemicals in a subject?s breath which could play a vital role in the non-invasive diagnosis of disease like diabetes in the future.
