Title: An investigation of the links between quality food production and biodiversity protection


1
An investigation of the links between quality
food production and biodiversity protection
Eating Biodiversity

Henry Buller University of Exeter
A Rural Economy and Land Use (RELU) project,
funded by ESRC, NERC and BBSRC,
2
What we would like to do today
  • Present the Eating Biodiversity RELU Research
    project
  • Discuss the research with practitioners,
    policy-makers and other actors
  • Listen to accounts from people involved in
    quality food chains and biodiversity management
  • Discuss some of the wider implications of the
    linkages between different aspects of quality
    and potential wins that we are researching

3
A RELU Research project
  • The Rural Economy and Land Use Programme aims to
    advance understanding of the challenges caused by
    rural change today and in the future.
    Interdisciplinary research is being funded
    between 2004 and 2009 in order to inform policy
    and practice with choices on how to manage the
    countryside and rural economies.
  • The Programme will encourage social and economic
    vitality of rural areas and promote the
    protection and conservation of the rural
    environment.
  • The Programme is an unprecedented collaboration
    between the Economic and Social Research Council
    (ESRC), the Biotechnology and Biological Sciences
    Research Council (BBSRC) and the Natural
    Environment Research Council (NERC). It has a
    budget of 24 million

4
Eating Biodiversity
  • By examining selected examples of specific food
    production chains that fully integrate
    biodiversity as an explicit means of generating
    distinctiveness and adding value, this research
    project offers an inter-disciplinary perspective
    by positioning biodiversity and environmental
    quality as an integral 'input' to, and component
    of, food quality.

5
Eating Biodiversity

This research seeks to develop opportunities for
win-win-win situations where farm enterprises
can gain added value from producing high-quality
products in terms of taste and nutrition from
significant biodiverse pasture types, such as
moorland, heathland and salt-marshes, in
ecologically sustainable ways. Our
interdisciplinary research is providing evidence
and analysis of the relationship between food
quality (defined according to both scientific
criteria and consumer perception), animal diet
(analyzed in terms of grazing composition) and
natural biodiversity (considered in terms of
species and community diversity), and is relating
this to implications for land use management,
farm practice and processes of rural
socio-economic development.

Eating Biodiversity

Phase 1 Research (Jan 05-Jan 06) Quality Lamb
Production on Biodiverse Pasture In order to
trace the relationship between biodiverse pasture
maintenance, agricultural practice and food
quality, the lamb-meat food chain has been
examined from pasture to plate. Sample farms,
where stock are grazed on significant natural
grasslands have been investigated. Botanical
surveys were undertaken, farm management
practices and farm businesses were studied (and
their relationship to nature conservation
prerogatives) and meat samples analysed (against
a control).

Research Objectives
Examination of management practices on farms that
identify distinctive pastures as an inherent part
of the food production system. Quantification of
the nature and extent of semi-natural unimproved
pastures.
11
Pastures
  • Three pasture types chosen
  • Salt-marsh
  • Heathland
  • Moorland
  • Four farms for each pasture type.
  • One control farm of improved grassland.

Ecological objectives
Identification of richness and importance of
biological communities present on each farm on a
regional, national or international
scale. Identification of plant species thought
to have a beneficial effect on animals health or
quality of meat produced.
14
Methodology
Relevé used enumeration of the species and
environmental factors in a small stand of
vegetation as a representative sample of a wider
area Each plant species within a sample recorded
with its percentage cover (vertically projected
onto the ground) Series of samples from
homogenous stands recorded and frequency of
occurrence and range of cover calculated Comparis
on to published plant assemblages made where
possible

Threats to species and habitats
  • Agricultural intensification,
  • Over grazing,
  • Inappropriate management, e.g. too frequent and
    too large burns,
  • Change to hydrological regime,
  • Climate change,
  • Nutrient deposition, e.g. atmospheric deposition
    and agricultural run-off.

30
Biodiversity as an input
Provision of grazing animal with more varied diet
in species-rich pasture than found in
species-poor semi-improved pastures.
31
Producers knowledges and practices
  • Owain Jones
  • Dept of Geography
  • University of Exeter

32
Range of producers visited
  • A whole range of farm types from small tenant
    farms on Dartmoor who also graze the commons, to
    large owned Scottish estates where the lamb
    production has to fit in with grouse shooting
  • Some producers now running established, thriving,
    businesses selling their entire flock output
    through alternative networks, some of which have
    on-farm meat cutting and packaging facilities
  • Others are small start up businesses selling a
    small percent of their flock directly (getting
    the processing done locally) (farm gate or local
    deliveries)
  • Some are organic and see this as important part
    of their product profile, others are not, feeling
    that their products come across as natural and
    as good as organic

33
Start up
  • All within the last 5-7 years (often informal
    starts)
  • prompted by
  • Falling farm incomes in the late 1990s
  • An awareness of the alternative local food
    movement (e.g. Edinburgh Farmers Market)
  • An awareness that this type of production will
    fit more easily with argi-environmental schemes
  • An interest in farm conservation issues
  • Often built upon the experience of killing a few
    lambs for family and friends and the feedback
    about the meat quality

34
(Changing) production practices
  • Some farms have not changed their practices that
    much. They were previously selling stock at
    market but came to realise their production
    system had latent added value
  • Others have
  • switched breed type (e.g. to Scottish Black Face
    flocks on Dartmoor)
  • gone organic to coincide with direct selling
  • stopped previous attempts to improve land
  • switched from developing output quantity to
    improve farm income to developing output quality
  • In some cases these changes have been made in
    relation to stocking agreements under
    agri-environmental schemes

35
Benefits
  • The farmers are getting a better price for lambs
    sold directly, (one tenant farm at Holker Hall
    told the manager that the better price had kept
    his farm going)
  • Some remarked that their quality of life in terms
    of job satisfaction and even mental health was
    improved by the challenge and reward of running a
    new business which had potential
  • Also in some cases they claimed to be happier to
    be producing food in more environmentally and
    animal welfare friendly terms
  • All pleased to get contact and positive feedback
    from their customers

36
Challenges
  • Setting up the business
  • Time
  • Capital
  • Expertise
  • Subsidy uncertainties/transitions
  • Setting up processing, packaging and delivery
    systems (trust)
  • Marketing/Selling
  • Selling enough volume (a lot of stock still goes
    to market)
  • What system to use?
  • Branding
  • Being a sales person
  • The seasonal nature (some accept this, others
    take measures to have all year round supply of
    lamb)

37
Selling methods
  • Farm gate
  • Local deliveries
  • Box schemes
  • Farmers Markets
  • Farm shops
  • Local butchers
  • Specialist meat wholesalers
  • Direct to catering trade
  • Websites (some examples later)
  • Leaflets (some examples later)
  • Food shows
  • Media coverage
  • Producers groups (umbrella)
  • (Where you are makes a difference)

38
Selling biodiversity
  • All the farms we have looked at make claims about
    the linkages between the quality of the meat
    products and the grazing thus in effect
    selling the landscape and biodiversity, e.g.
  • saltmarsh grasses, samphire, sea lavender and
    thrift , give the meat a distinctive and very
    special flavour
  • (They also feel stock and meat handling processes
    are very important)

39
Biodiversity as a unique selling point and ground
for premium quality claims
  • These claims are an obvious means of giving
    products an USP, and for supporting claims of
    premium products and thus added value
  • LFAs with natural grazing can find themselves
    with an advantage over improved lowland farms
  • Historically, much UK biodiversity has been a
    happy accident stemming from traditional
    farming practices. This undone by post-war
    intensification. Now a new reflexive relationship
    is being/needs to be developed
  • We are also interviewing relevant personnel in
    nature/landscape conservation/management
    organisations

40
Towards recommendations
  • Not a magic bullet
  • but an increasingly important component of
    sustainable rural land use management which has
    the capacity to grow further
  • Help with start up is important (e.g. RES
    grants, advice, producer group set up)
  • Supporting the market by
  • Public information (media coverage)
  • Oiling the wheels (small scale public
    procurement??)
  • Protecting through PDOs and the like
  • Supporting/enhancing local food chain
    infrastructure
  • Ensuring agri-environmental schemes and
    management have an eye for this kind of
    production and try to gear with it as much as
    possible. Linking with GAP schemes

Taste assessed by a trained panel
51
Shelf life
  • Lambs from all pasture types had good colour
    shelf life
  • Levels of lipid oxidation products in meat from
    all lambs were below those which lead to
    rancidity
  • Vitamin E levels were high in all lambs,
    particularly in those grazed on heather

52
Health
  • All groups of lambs had similar muscle fat
    contents (3)
  • Heather and moorland were higher in all n-6 fatty
    acids and also C226n-3
  • Moorland lambs had higher CLA levels in relation
    to trans-C181

53
Taste
  • Flavour scores for all lambs were high, with meat
    from moorland and saltmarsh lamb scoring highest
  • Fat from lambs grazing semi-improved control
    pasture scored highest for abnormal odour and
    lowest in lamb flavour

54
And finally
  • This study shows that lambs grazing
    unimproved pasture produce meat that is of high
    quality and tastes good.

55
Consumer Perspectives

James Kirwan and Carol Morris Universities of
Exeter and Gloucestershire
56
Consumer perspectives
  • Consumer perspectives on the linkages between
    food quality, biodiversity and farmland
    management
  • How information about products may/ does
    influence purchasing decisions
  • Scheduled for year 3 of the project
  • 4 focus groups - 3 meat quality 1 cheese quality

57
Focus group pilot
  • Pilot focus group of 10 women held in February
    2006
  • Themes discussed
  • Shopping for meat (at home and on holiday)
  • Production processes, and the perceptions of
    the impact of these processes on the food
    consumed
  • Labels and labeling
  • Reflections on food quality

58
Images discussed during the focus group
  • Leaflets salt marsh lamb and Northumbrian
    Quality Meats
  • Images from websites. e.g. Holker and Heritage
    Meats.

63
Focus group pilot some results
  • Place of production was seen as important but not
    as significant as price
  • Quality of meat was more significant in
    purchasing decisions than price, with taste and
    appearance also significant
  • Limited knowledge / concern about food production
    issues (especially environmental issues)

64
Response to information about salt marsh lamb
  • the salt marsh bit puts me off somehow.
  • Yes, and me.
  • Because of the salt.
  • You'd think it might be salty.
  • You'd taste salt.
  • And marsh land, is just a boggy mess.
  • But, factor in the place of production
  • The Gower salt marsh lamb, I know the Gower and
    it is a
  • lovely place, so that could influence me

65
Response to pictorial information
  • I think Northumbrian Quality Meats doesn't
    really mean much.
  • The taste of Northumberland, what is the taste of
    Northumberland?
  • The salt marsh one says where it comes from.
  • The Northumberland one is a bit vague.

66
To end
  • Consumer responses to communication /messages
    cannot be taken for granted, and are not
    straightforward!
