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.
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.
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.
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.
Satellites is also now working with Nigerias National Space
Research and Development Agency (NASDRA) to help government agencies
reduce the impact of possible natural disasters.
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.
presenter James Chau travels to Chinas largest city, Shanghai,
where the Chinese Government has set itself the target of growing
95% of the citys vegetables in the local area.Theyve
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 Shanghais urban area.
