Prequisites
Intended Learning Outcome After the completion of this course, the participants will be able to:

  • know the various water resources used for irrigated agriculture and their respective interdependencies.
  • know the relevant physical and chemical soil properties for irrigation, including leaching and drainage.
  • know the importance and demands for the various irrigated crops.
  • know the various irrigation methods, their effi ciencies and their influence on the soils and the groundwater.
  • Students are aware of the water use in irrigated agriculture in comparison with the other sectors and the relation to the IWRM-concept.
Content Introduction

  • Rainfed versus irrigated agriculture: global and regional importance regarding: water demand, economic, environmental and social impact and food security
  • IWRM relation: conflicts over land and water uses between agriculture and other sectors (housing, energy)
  • Water management at different scales: water uses, key-stakeholders, water user’s associations

Water use and productivity

  • Climatic factors and infl uences by climatic change
  • The role of eff ective rainfall

Soil Characteristics

  • Physical and chemical soil characteristics and their relation to soil water,irrigation and drainage.
  • The various approaches to determine the potential evapotranspiration (PET), the crop water and irrigation requirement as well as the pre-irrigation requirement
  • Non-point sources (NPS) of pollution (sediments, nutrients, pesticides, salinity,..)
  • Diagnosis of the salinisation process. Determinations of the leaching requirement and combination with the overall farm water requirement.

Irrigation, groundwater and drainage technologies and systems

  • Irrigation technologies and systems
  • Water resources for irrigation and their qualities
  • Water lifting devices, including pumps
  • Water storage, conveyance and distribution systems
  • Water losses and water use efficiencies (system and field)
  • Options to increase efficiencies

Water allocation principles in agriculture

  • Continuous versus intermittent irrigation
  • Irrigation on demand versus rotational irrigation
  • Deficit irrigation
  • Plant nutrients and fertilization management
  • Water re-use options
  • Organisational aspects of agriculture; participation, water user groups, water user associations
  • Maintenance of irrigation and drainage infrastructure
  • Environmental aspects
  • Water use conflicts in irrigation systems and outside; relation to IWRM concepts
