Production by 2050. PLoS ONE 8(6): e66428. doi:10.1371/journal.pone.0066428
http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066428
---2.4% growth required to double production by 2050
Linear growth starting 1970
60% increase
4. Challenges to global crop production
• Climate unpredictable,
warmer, drier, etc.
• Depleting water resources
• Emerging diseases and
pests and their new biotypes
• Energy and fertilizer costs
• Declining agricultural
research capacity in LDCs
• Soil degradation and
erosion…..

5. • 30% of the world’s arable land lost to
erosion or pollution in the last 40
years.
• Erosion rates from ploughed fields
averages 10-100 times greater than
rates of soil formation.
• It takes about 500 years to form 2.5cm
of topsoil under normal agricultural
conditions.

6. • Today more people are hungry than entire population of
South Asia at beginning of Green Revolution (1970)
• No. people living on <$2 /day same as in 1981 (~0.7 billion)
• 180 million children <5 years malnourished – in Africa 40%
of all children <5

11. • IWIN germplasm increased productivity for >100m farmers in LDCs
(Lipton, Longhurst 1989; Evenson, Gollin 2003; Pingali et al., 2012)
• MVs saved >20 m ha land from cultivation (Stevenson et al., 2013)
• IWIN-related varieties cover over half wheat area in LDCs, giving
additional value of US $2.2-$3.1 billion p.a. spread among both
resource poor farmers and consumers (Lantican et al., 2016)
• The benefit-cost ratio of this investment is over 100:1
(without considering avoidance of devastating disease pandemics)
• IWIN has also amassed a database of over 11 million data points

24. Research questions:
1. Can crop models simulate extreme H-yielding wheat (EHYW)?
2. What climate characteristics are required for EHYW?
3. What crop management is required for EHYW?
4. What crop traits are required for EHYW?

31. HeDWIC Development
Broad consultation (370 people, 77 institutes, 32 countries):
Determine most promising/necessary research areas
Arrange traits/gene research into a rational framework
Develop an organizational structure that facilitates
translational research to breeding
Develop a bioinformatics cyber-infrastructure to support
research and delivery
33. Priority of heat & drought
• Poll conducted on relative priorities for EWG AWAS
• Heat and drought stress, i.e. HeDWIC clearly the top priority
34. Resource Capture and Utilization Efficiency
Maximize the potential for biomass production at warmer ambient
temperatures and with less predictable rainfall/reduced irrigation :
Root systems - function, architecture & biotic interactions
Thermostability of membranes and enzymes
Metabolic adaptations to heat and drought (including
osmotic adaptation, and cellular tolerance of stresses)
Respiration, oxidative stress, & photo-protection
Transpiration efficiency, gas exchange and carbon balance
Canopy architecture, development and senescence
GxExM
35. Reproductive Growth & Resource Partitioning
Maximize partitioning of biomass to HI and nutritional quality:
Optimising floret fertility
Stress perception and signalling
Carbohydrate storage and partitioning to grain filling
Effects of stress on end-use quality
Crop architecture for yield stability
Phenology for stress avoidance
37. Setting up international collaborations
• Clear focus and targets
• Pre-existing informal network
• Survey literature & current research portfolios
• Develop a proposal but don’t overly prescribe
• ‘Theory of change’
• ‘Business case’
• Be prepared for a lot of leg work
• Expect grey hairs!
