Abstract:
Accelerating volatility, complexity and scrutiny will be the norm in the landscape for
agribusiness value chains as the future unfolds. Evidence of this new landscape is clear
from the extent and intricacy of global food and fibre value chains, the rise of
consumerism, and the prominence of the sustainability and responsibility narrative. As
a result, agribusinesses and their value chains are compelled to evolve to meet the
challenges and opportunities that this new landscape presents. However, agribusinesses
and their value chains generally seem lethargic to adapt to this new environment and
are consequently every so often ensnared by a cascade of effects that highlight the
volatile, complex and scrutinising challenges for these value chains. Confirmation of
these cascading effects is evident from the range of food scandals, product recalls,
instantaneous bankruptcies, and reputation and brand devastation, where unexpected
events lead to these, and other, non-linear payoffs that ripple through these chains. The
conspicuous occurrence of these events with non-linear impacts is indicative of fragility
in these chains and specifically highlights the rationale for detailed exploration of
fragility, as a phenomenon, in agribusiness value chains. This thesis addresses this
overlooked phenomenon by threshing out the factors that cause fragility, by developing
a framework to quantify fragility, and finally by exploring the interaction between
fragility and the coordination of agribusiness value chains. Through a normative Delphi approach with key stakeholders and a principal component
analysis, this thesis explored the factors that contribute to agribusiness value chain
fragility in selected meat, fibre and fruit chains and found that those factors that
contribute to the efficiency of value chains are also the factors that drive the fragility of
these chains. This finding exposed a juxtaposition between value chain efficiency and
fragility and the need to find a measured balance between these approaches to achieve
and sustain chain goals. The thesis develops a framework to measure agribusiness value
chain fragility and applies this framework to the South African lamb value chain
through a modified value chain analysis methodology. This framework exhibits the
detection and quantification of fragility at the factor, stakeholder and chain level in the
particular chain. The thesis finds a golden thread of specific factors that are critical to
the fragility of the particular chain. The whole chain of actors is fragile to the actual
quality and safety performance and the cash flow position of actors in the chain.
Likewise, the thesis also finds nuances in specific factors that are critical to the fragility
of the particular actors in the chain due to the activities’ unique techno-economic
characteristics. Producers are uniquely fragile to buyer and operational reliability,
abattoirs to the quality and training of human resources, and the quality and adequacy
of infrastructure, packers to regulations and supplier reliability, and retailers to the
management information and supplier relationship and alignment. The idiosyncrasy is
that activity-specific fragilities could, unpredictably, cascade into the rest of the chain
due to sequential interdependencies in a typical chain. Quantification of the fragility of
the South African lamb chain also establishes that increasing coordination intensity and
interdependency in the chain increase the fragility of the chain. Hence the thesis argues
that traditional transaction costs economising model that guides the coordination
strategies of successive exchanges in value chains may, in fact, contribute to chain
fragility in the effort to economise on the costs of exchange.
Conscious of the findings of the analyses the thesis argues that complex systems like
value chains are unavoidably exposed to human limitations in their design and
management. Humanity appears challenged in coping with complexity, and as a result,
the coordination of value chains oscillates between hubris and nemesis in pursuit of
coordination precision – sailing too close to the wind and then crying foul when the
inevitable happens. Therefore, the thesis makes a case for a more mindful and less ‘fragilising’ approach to the coordination of value chains by arguing that both fragility
and the cost of exchange be considered in the governance of chains. The shortcoming
of the traditional approach is laid bare by the growing frequency and impact of events
with cascading consequences that ripple through chains. Hence the thesis’ argument is
contrary to the traditional transaction costs economising model that only considers
economising on the costs of exchange, at all cost, in the coordination of value chains.
