Samenvatting - Lectures

  • 1 Organic Trends

  • How did organics starts?
    As a philosophical approach; healthy soil= healthy food= healthy people
  • What are the organic principles?
    - Farm as living organisms
    - Inherent fertility
    - Intrinsic linkage
    - Pragmatic
    - Principle of health
    - Principle of ecology
    - Principle of fairness
    - Principle of care
  • What does farm as living organisms mean?
    Closing of cycles (nutrients) system that is responsive and adapted to its environment
  • What does inherent fertility mean?
    A 'living soil' transfers health and vitalit to elements higher in the food chain
  • What does intrinsic linkage mean?
    An intergrated and complex system that is self regulating though dynamic processes
  • What is pragmatic?
    Innovations may be obtained through on farm experimentation. observation and traditional research using rational and scientific approaches
  • What is the principle of health?
    Organic Agriculture should sustain and enhance the health of the soil, plant, animal, human and planet
  • What is the principle of ecology?
    Organic agriculture should be based on living ecological systems and cycles, enhance and sustain them
  • What is the principle of fairness?
    Organic agriculture should build on relationships that ensure fairness regarding the environment and humans
  • What is the principle of care?
    Organic agriculture should be managed in a precautionary and responsible manner to protect the health and well-being of current and future generations and the environment
  • What is biodynamic agriculture?
    Anthroposophic approach based on awareness of the spiritual dimensions
  • What are the charasteristics of biodynamic agriculture?
    - Comprehensive and intergrated (mixed) farming system
    - Animal welfare
    - Site-specific rotations: rooting & soil feeding characteristics
    - Use of seeding and harvesting calendar
    - Use of organic amendments to vitalize the soil
    - Use of special preparations to enhance soul humus formations and composting processes
    - Special certification label
    - Globally 142,482 ha certified as biodynamic
  • What are the market trends in organic agriculture?
    - Most products sold in supermarkets
    - Diversification of marketing strategies
    - Food processed/consumed in developed regions
  • What are opportunities and threats when most products are sold in supermarkets?
    - Allow efficient marketing and distribution
    - Facillitates growth and expansion
    - Increased specialization, intensification and price pressure
    - Biases towards large scale production
    - Risk of conventionalization of organic food networks
  • What are the opportunities with diversification of marketing strategies?
    - Increased adaptive capacity
    - Improved resilience of organic farmers and food networks
  • What are the opportunities and threaths with food processed/consumed in developed regions?
    - Increased food miles
    - Decrease in consumer participation and local food security
    - Disconnect between producers and consumers
  • 2 System Analysis

  • What is a system?
    - A limited part of reality that contains interrelated elements
    - Groups of parts (or sub-systems) that are interacting to some kind of process
    - System as a whole is different from the sum of its parts
  • What are the elements of a system?
    - Inputs
    - Outputs
    - Boundary
    - Interrelationships
    - Components
  • What is important in systems design?
    - Structure determines behaviour as a whole in response to stimuli to any part
  • What is the definition of a farming system?
    - Multiple dimensions
    - Governed by natural processes
    - Influenced by management and design
    - System definition depending on research questions
  • What do we look at when we do systems analysis?
    - System properties in relation to their own structure and functioning
    - System properties in relation to changes in external driving variables
  • What are system properties in relation to their own structure and functioning?
    - Productivity/efficiency
    - Diversity (structure)
    - Stability
  • What are system properties in relation to changes in external driving variables?
    - Reliability
    - Adaptability
    - Resillience
  • What is redesign?
    A continuous process in which Multi-criteria evaluations play a central role
  • What are the steps of redesign?
    - We compare systems through comparing indicators
    - Indicators are choses to reperesent key system properties
    - System properties reflect structural and functional charasteristics of a system
  • Which levels of inergration and systems design are there?
    - Optimisation of existing techniques
    - Redesign of products and processes
    - Innovaion of system functions
    - Novel system
  • What is an agroecosystem?
    An ecosystem that has been modified by humans for the production of food, fibre, energy and services; agroecosystems have multiple dimenstions. Their funcioning can be influenced through design
  • Why are system properties important?
    When it comes to choosing indicators to evaluate and monitor sustainability
  • Where does system analysis consists of?
    haracterizing their structure, dynamics and fuctions; some system properties depend on internal processes, while other emerge as a respponse to changes in external drivers
