Title: Ian McClelland


1
  • Ian McClelland
  • Chairman MCV program
  • Contributors
  • Colin Creighton
  • Dr. Barry White
  • Dr. Peter Hayman

2
  • Two Farmers
  • Wizard Clairvoyant
  • Making the right decision - Foresees the future
  • Understands climate risk - Acts with knowledge
  • Has knowledge and understanding - Probability
    working for him

3
  • MCV Program
  • Developing new weather forecasts and products
    that meet Australias agricultural needs
  • Improving capability of farmers to make better
    management decisions around climate variability
  • Farmers having the right skills to understand
    weather systems

4
Why we focus on climate variability as opposed to
climate change?
Roger Jones CSIRO
5
What destroyed the sand castle ? In a variable
and changing climate it will always be hard to
distinguish between extreme events (wave) and
trends (tide)
6
  • What do we want farmers to adopt from MCV
    program?
  • Wise decisions instead of lucky decisions
  • Assess risk
  • Understand climate data
  • Access data relevant to their specific locality
  • Confidence Dare to risk

7
Climate variability has a crucial relationship to
profitability
Federation drought 1895 to 1902
WWII drought 1937 to 1945
Millennium drought 1997 to now

Severe prolonged drought
Severe single year drought

  • Achievements and challenges over 18 years.
  • Change from drought research programs and
    managing droughts to climate variability programs
    for all seasons that include climate risk.

include IOD, SAM IPO

3. Development of management tools AussieGRASS
was one of the first projects funded and involved
7 State Government Departments with Rangelands
responsibilities. (now self funding) AussieGRASS
develops a pasture growth or ground cover outlook
a season ahead using a well validated pasture
growth model.
  • The outlook reflects
  • Current soil moisture
  • Current pasture levels, and
  • The seasonal rainfall forecast

4. Understanding probability Yield Prophet

  • 5. MCV Program relevant to many industries
  • - MCV fund most long term weather
    forecasting programs
  • - Challenge to attract new participants

23
6. Improved weather forecastingBiggest early
challenge Getting the message across and back
  • When are seasonal forecasts most useful?
  • Winter-spring in eastern Australia
  • Areas in red show rainfall deficiency in winter
    spring in 12 El Niño years.
  • Perception of little value in
  • southern Australia
  • SW Western Australia

24
  • Years with the worst wheat crops nationally have
    all been El Niño years. (But not all El Niño
    years are widespread droughts.)
  • Probability forecasts - a hard sell - They only
    shift the odds half the time in half the places
  • Users are hard markers -sometimes only confusion
    reigns down

25
7. Climate champions and masters of climate
material
26
8. Limitation of climate forecasts
  • Taking into account soil type, topography and
    management
  • 9. The difference between observed seasonal
    climate forecast and those used as a management
    tool
  • 50 of farmers use SCF but have a certain lack
    of confidence in long term forecasts

27
Priorities and scores
  • Rebadge away from origins as a 2.1m part of the
    1992 NDP 8/10
  • Involve most Rural RD Corporations 9/10
  • Better seasonal forecasts 5/10
  • Better feedback
  • users forecasters
    8/10
  • Give priority to worlds best generic products to
    give all farmers and NRM users timely and local
    climate knowledge 10/10

28
RD Strategy 2008-2014
  • Four themes -
  • Forecasting
  • Soil, climate water attributes
  • Tools for Agriculture
  • Knowledge, adoption communication
  • Partnership across LWA, GRDC, MLA, DA, RIRDC,
    SRDC
  • A 4.7 1 benefit cost ratio over the last 15 years

29
Forecasting
  • Global Circulation Models
  • - a major research challenge as we recognise the
    dynamic nature of our climate
  • already providing increased certainty and local
    relevance in forecasts
  • our investments focus on where improved skill
    will benefit agriculture
  • Multi-Week Forecasting
  • - breaking down the barriers of weather climate
  • - fostering within season climate risk
    management
  • Relevance
  • ensuring forecasts and products that meet
    Australian agricultures needs

30

31
  • The future prosperity of our agricultural
    community will depend on
  • More qualified and skilled professionals
    supported by science and technology.
  • Continual adjustments in agricultural practices
    as climate variability becomes more pronounced.
  • The MCV program still has much more to achieve.

Reflecting on the first decade
  • Lack of continuity uncertain funding drought
    dependent competing with climate change
  • Equitable funding ? free-riders abound,
  • Confusion from cottage industry of alternative
    forecasts
  • How to get probabilities across - customers are
    ambiguity shy (prefer certainty to knowledge)
  • Taking a new a new RD focus to 100,000 farmers
    on 1m per year ( if you were lucky)
  • The challenge - more attractive to modelers than
    to communicators ( only some could do both at the
    same time!)

38
To summarise key investment opportunities
  • For RD Strategy to 2014 and our 4 themes -
  • Forecasting tropical, especially monsoon / wet
    season and east coast
  • Soil, climate water attributes soil moisture
    prediction and on-farm calibration.and
    implications for fertiliser, weeds diseases
  • Tools for Agriculture harvest season prediction
  • Knowledge, adoption communication data drill
    and multi-week products on WATL
  • Commissioned and output focussed RD to maximise
    benefitcost ratio
