Mexico, 23 April 2009
• New variant A/H1N1 first confirmed.
• A random viral reassortment resulting in a new strain
- mixture of swine (pig), human and avian influenza viruses.
- Not clear where, when or in what host this occurred
- Virus may have been circulating in Mexico for some time
• Reassortments happen all the time. Occasionally the new virus
- May become more transmissible
- May become more severe
- May switch host target.

By 2030:
Agricultural production
More people means less cultivated land per person
for food, feed, (agro)-fuel and fibre production

The challenge
Need:
50% more production on
less land, with less water,
using less energy, fertiliser
and pesticide …
…by 2030
… whilst not increasing
GHG emissions

• Genomics to provide targeted and predictive non-GM plant breeding
(e.g. for yield, sustainability, quality)
• Work on crop improvement e.g. increased disease resistance
• GM may also provide future solutions, notably for improved drought and
saline tolerance; and resistance to pests and disease

Opportunities for science and
innovation
The new TSB Sustainable Agriculture and Food Innovation Platform will
see investment of up to £90 million over the next five years.
It will focus on:
• Crop productivity including protection and nutrition
• Sustainable livestock production
• Waste reduction and management
• GHG Reduction technologies and Methodologies

Hansen (US) and
Wigley /Jones (UK)
used statistical
techniques to show
global temperatures
had been rising since
the mid 1960s
• First robust records of global temperature
change
• They accounted for ‘data gaps’ in the
Southern Hemisphere and over the oceans
Appropriate analysis
Correct use of
statistics
is critical for the
communication
of climate change

Foresight Project:
Mental Capital and Wellbeing
This project aimed to use the best available scientific
and other evidence to develop a vision for:
•
The opportunities and challenges facing the UK
over the next 20 years and beyond, and the
implications for everyone’s “mental capital” and
“mental wellbeing”.
•
What we all need to do to meet the challenges
ahead, so that everyone can realise their potential
and flourish in the future.
The MCWB Lead Expert
Group have recently
published their expanded
findings as an important
reference work.
