5th European Symposium Industrial Crops and
Products

• Agriculture and Biocascading

2
Fine tuning of plants to changing demands

• Rudy Rabbinge
• Wageningen University and research centre

3
Agriculture

• Producer of various products
• 10 Fs
• Pharmacy, Flavors, Fragrance, Flowers,
  Vegetables, Fruit, Food, Fodder, Fiber and Fuel

4
Agriculture

• Quantitative
• Productivity and required land use to fulfil
  demand.
• Qualitative
• Characteristics of products and production
  systems.

5
Dilemmas

• non-food food
• Bulk production niche markets
• Added value by Added value specialized
  products by chain management

6
Non-food

• Historical
• before the chemical revolution
• Fiber energy gt considerable contribution, large
  demand
• Pharmacy flavors gt substantial contribution,
  limited demand
• after the chemical revolution
• - no bulk production for agricultural non-food
• - considerable reduction on specialized products

7
Non-food

• Biological revolution
• new perspectives for non-food
• pharmacy, flavors, fragrance
• specialized bulk production
• cascading

8
Some elementary concepts of crop growth

• Production situations
• Photosynthesis
• Energy flows
• Respiration and biosynthesis
• Crop growth
• calculated
• measured

9
Production situations with corresponding yield
levels
10
Photosynthetic processes of C3 and C4 Plants
11
Energy flow in crop production
12
Respiration losses C3 and C4 plants
13
Some characteristics of the biosynthesis
14
Calculation procedure for daily crop
15
Growth rates of main agricultural crops in the
Netherlands
16
Different types of chains and strategies

Conclusions

• Good perspectives for plants as factory
• secondary metabolites
• well defined characteristics
• Pharmacy, flavors, fragrance and high values
  macro molecules
• Limited perspectives for plant as bulk produces
• fiber for fuel
• Perspectives for plant in chains
• biocascading
• C5 / C6 sources
