General problem in practice
  • Reducing availability of water necessitates
    transition in agricultural practices
  • Changes in crop choice
  • Changes in farming / integrated systems
  • Development of new agronomic practices
  • Exploiting non-terrestrial systems
  • Conversion of current cultivation practices

Changes in farming / integrated systems
6
Development of new agronomic practices
7
Exploiting non-terrestrial systems
  • Minimal improvement of marine crops
  • Advanced breeding techniques allow improvement of
    marine species
  • Production potential great
  • Novel proteins
  • Medicinal aspects

8
Water-less rice
Converting inundated rice cultivation into dry
rice
9
Why research on rice ecosystems?
  • heavy water consumer 5000 l/kg rice
  • important food crop 50 of the world population
  • in Asia 80 of caloric intake is rice
  • food security lt--gt water security

10
Rice - wet or dry
  • land preparation
  • weed control
  • water buffer
  • inflow of nutrients
  • nitrogen fixing organisms
  • dissolving nutrients
  • controlling acidification
  • diseases
  • fish

11
Changing conditions - changing practices
  • Labor requirement and direct seeding
  • Land pressure and multiple cropping
  • Water scarcity and water-less-rice production
  • Global climate change and methane emission in
    rice fields

Foreseen developments
  • From macro to micro irrigation
  • From inundated to dry cultivation of rice
  • From dry land cropping to micro irrigation
  • High value crops
  • Bulk food crops (Sugarcane in India)
  • Bulk Fiber crops (Cotton)
