Title: An investigation of the links between quality food production and biodiversity protection
1An 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,
2What 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
3A 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
4Eating 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.
5Eating 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.

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).

10Research 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.
11Pastures
- Three pasture types chosen
- Salt-marsh
- Heathland
- Moorland
- Four farms for each pasture type.
- One control farm of improved grassland.
12Saltmarsh
Heather

Moorland
13Ecological 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.
14Methodology
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

29Threats 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.
30Biodiversity as an input
Provision of grazing animal with more varied diet
in species-rich pasture than found in
species-poor semi-improved pastures.
31Producers knowledges and practices
- Owain Jones
- Dept of Geography
- University of Exeter
32Range 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
33Start 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
35Benefits
- 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
36Challenges
- 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)
37Selling 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)
38Selling 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)
39Biodiversity 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
40Towards 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

50Taste assessed by a trained panel
51Shelf 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
54And finally
- This study shows that lambs grazing
unimproved pasture produce meat that is of high
quality and tastes good.
55Consumer Perspectives
James Kirwan and Carol Morris Universities of
Exeter and Gloucestershire
56Consumer 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
57Focus 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
58Images discussed during the focus group
- Leaflets salt marsh lamb and Northumbrian
Quality Meats - Images from websites. e.g. Holker and Heritage
Meats.

63Focus 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)
64Response 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
65Response 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.
66To end
- Consumer responses to communication /messages
cannot be taken for granted, and are not
straightforward!
