Systems Thinking and Food Security

Dr Alex ArnallReading IFSTAL Principal InvestigatorandDr Harley PopeReading IFSTAL Educational Coordinator#IFSTAL

What are the food system challenges?

against a background of

natural resource depletion

and many stagnating rural economies andchanging climate andsocial and socio-cultural changes

To achieve food security for a

growing, wealthier, urbanising population while minimising further environmental degradation

Human systems are:

Global in scope

Dispersed and interlinked

Complex

Reflect patterns of socioeconomic inequality

‘Tame’ problems: complicated but solvable

Well-defined and stable problem statementDefinite stopping pointSolutions can be: Objectively evaluatedSolutions can be generalised to similar problemsTried and abandoned

‘Tame’ problems: complicated but solvable

Well-defined and stable problem statementDefinite stopping pointSolutions can be: Objectively evaluatedSolutions can be generalised to similar problemsTried and abandoned

When n% of plants survive under a particular set of abnormally dry circumstances

‘Wicked’ problems: complex and intractable

Solutions are poorly-defined and contested, thus commonly defying attempts at resolution Transcend disciplinary, organisational, institutional, and geo-political boundaries

‘Super-wicked’ problems..?

Time is running outNo central authorityThose seeking to solve the problem might also be contributing to itPolicies discount the future irrationally

Overfishing

Major food producing activity 90 million tonnes wild capture per yearIntegrated into global food systems Fish: livelihood, dietary and culture significance Up to 85% of world’s fisheries over-exploited / depleted or recovering

Tackling overfishing

Three possible strategies: Authoritative: enforcement of laws Competitive: consumer awareness Collaborative: awareness in fishing industry

1. Unexpected / unwanted outcomes

Lose sight of the bigger picture Particular solutions, when implemented, can cause problems elsewhere in the system

2. Incomplete knowledge

3. Power dimensions

Tackling complex problems is essentially a political process… …Something often denied or downplayed Reliance on bureaucratic, rationalist decision-making frameworksExclusion of groups from decision-making processes

What is a System?

System‘a complex whole of related parts’Systems ThinkingThinking about thinkingThe consideration of something in its totality, its interaction with the wider environment, while also considering its constituent parts and their interactions Systems MethodsIncludes concepts, frameworks and methods that support our ability to think systemically in different contexts

A Representation of a Food System

System Properties

Systems can have levelsSystem parts can be ‘nested’ in each otherIndividual agents or system parts can aggregate to form patterns of behaviour such as self-organisation and new functions - emergence

System Dynamics

System behaviours can form patterns:FixedPeriodicComplexChaotic (random)

A Representation of a Food System

Complex Adaptive Systems (CAS)

Systems with multiple elements adapting or reacting to the patterns these elements createInteresting properties of CASs:Time / Distance separation of outcomesPath DependenceResilienceTipping Points (self-organised criticality)

Food Waste - Distinctions

DefinitionsWhat it is and what it isn’t (boundaries)

Food Waste - Systems

Who is creating it? Where is it created?

Food Waste - Relationships

How, why and when is waste being generated?Who bears the cost? Can it be distributed?

Food Waste - Perspectives

To what extent is waste a problem?How do individuals, groups and organisations see it?Is food waste linked to other problems?

Doing Systems Thinking

There is no definitive vision of the food system to discoverWhen looking at systems we have to deal with incomplete knowledge, power dynamics and different perspectivesWe use systems thinking to enhance our understanding through uncovering relationships and identifying opportunities to intervene and communicateSystems methodologies can help us apply our systems thinking
