The rationale for sustainable intensification and agroecological approach

  • Population Growth
  • Environmental challenges from intensifying

farming activities

  • In order to achieve sustainable intensification

policy makers, academics and growers need to increase their understanding and develop agroecological principles

  • Weeds - Blackgrass, Crop Volunteers

crop competition, cultural, chemical, alleopathy

  • Pests - Slugs and Insects

Cultural, ferric, seedbed

  • Disease – Fusarium, Septoria, Yellow Rust

rotation, variety choice, PPP
