2Aims of the presentation
- Discuss the nature of scales and levels in human
systems. - Show how a food systems framework helps
identify key aspects of human systems in the
context of food security. - Show value of research at regional level in
helping to link between global and local levels
in human systems. - Give examples of how the human dimension of food
systems can enhance or hinder food security.
3Scale and Level (Cash et al, 2006, Ecology and
Society )
Scale the quantitative or analytical dimension
used to measure and study any phenomenon Level th
e unit of analysis that is located at different
positions on a given scale
4Different scales and levels critical in
understanding and responding to food system
interactions

7Food security
... exists when all people, at all times, have
physical and economic access to sufficient, safe,
and nutritious food to meet their dietary needs
and food preferences for an active and healthy
life. (World Food Summit 1996)
8Why choose Food Security for thinking about
scales and levels in human systems?
- Food security is a fundamental human goal.
- Pursuit of food security has been intimately
interwoven with the evolution of many
human/societal structures, eg - laws regulations
- customs ceremonies
- trade commerce
- These structures operate on several scales (e.g.
temporal, jurisdictional, ) and at several
levels within each scale (e.g. national,
regional, ). - Interactions between and within these scales are
critical to understanding the controls on food
security and interactions with the Earth System.

... is underpinned by Food Systems.

resources, inputs, markets, Processing
packaging food raw materials, standards, storage

113 key Scale Challenges situations in which the
current combination of cross-scale and
cross-level interactions threatens to undermine
food security
Ignorance the failure to recognise important
scale and level interactions in food systems
altogether, e.g. El Nino-induced changes in
anchovy catch in the E Pacific and N-efflux from
global soyabean production Mismatch the
persistence of mismatches between levels and
scales in food systems, e.g. food security
responses for weather extremes planned at
national level vs. community level Plurality the
failure to recognise heterogeneity in food
systems in the way that scales are perceived and
valued by different actors, even at the same
level, e.g. local food aid programmes vs. local
social safety-nets
Based on Cash et al., 2006 Ecology and Society
12Regional-level studies help identify Scale
Challenges when trying to link global to local
food security issues
- 1. Climate and weather-related perturbations are
often experienced and are increasingly
available at the regional level - adaptation strategies focussed on human systems
may prove more effective if managed at the
regional level. - Environmental management issues related to food
security may manifest strongly at regional level - solutions to such problems may often require
supra-national policy considerations (e.g.
agreements on inter-basin transfers of water). - Regional governance structures have been
established in many parts of the world - offer a clear client for discussing research on
scale challenges.
13Scale Challenges across human systems at
regional scale 3 examples for southern Africa
Food System ACTIVITIES Producing Processing
Packaging Distributing Retailing Consuming
- Food trade
- global vs. regional formal/informal trade
- Food distribution
- food aid in 91/92 drought
- Food retailing
- the role of supermarkets
141. Food trade Formal informal trading systems
operate at different levels and are often nested
and/or overlapping
Informal cross-border trade Malawi received ca.
75 of the total amount of maize traded
informally in the region (WFP, 2006).
15Example Scale Challenges related to food trade
- Ignorance
- Formal national and donor food security
strategies may not account for informal trade
- Mismatch
- Trade barriers and lack of harmonisation of
trading systems and tariffs constrain food
movements across borders
- Plurality
- Both formal and informal trade systems key to
satisfying national food security
162. Food distribution 1991/92 drought
- 2.6 million sq miles stricken by drought
- 86 million people affected
- 20 million people at serious risk
- 1.5 million refugees and displaced people
- Six corridors for food aid shipments from
regions main ports Dar es Salaam Nacala Beira
Maputo RSA Walvis Bay Luanda - Example human system impediments
- Different quarantine regulations
- Transit toll fees
- Poor port labour management (no incentives to
work more than necessary)
17Example Scale Challenges related to
distribution of emergency food aid
- Ignorance
- National toll quarantine policies vis à vis
regional donor approach - Global response vis à vis poor regional port
management
- Mismatch
- Jurisdiction of the national institutions not
coterminous with supplying food to region - Urgency of food need poorly-matched with
institutional response speed
- Plurality
- Conflict between humanitarian requirements and
commercial concerns - Variety of objectives among donors, recipients
and regional institutions
183. Food retailing The increasing role of
supermarkets
- Rapid rise of supermarkets in the southern
Africa, proliferating beyond middle-class
big-city markets into smaller towns and poorer
areas - Transforming the food retail sector (already gt55
of South African food retail) - Changing consumption patterns more choice
strong marketing usually promoting more processed
foodstuffs - Supplying supermarkets potentially offers large
opportunities for producers but also presents two
big challenges - procurement systems involve purchase
consolidation, a shift to specialised wholesalers
and tough quality and safety standards - investments and new practices is hard, esp. for
small producers
19Example Scale Challenges related to supermarkets
- Ignorance
- Small scale producers have little information
about standards for food quality and processing
- Mismatch
- Supermarket purchasing systems not well suited to
many small producers
- Plurality
- Processed foods are increasingly available but
erode traditions based on local food
20Conclusion 1 Helps set cross-scale, cross-level
research questions
How would interactions among rules, laws and
constitutions affect food system adaptation at
different spatial levels? How would short-term
changes in donor philosophy for food- and
seed-aid as applied at the local level affect
long-term regional self-reliance? How would
implementing different short-term adaptation
policies in different nations influence regional
food security goals?
