Abstract: | Irrigation Advisory Services (IAS) are the natural management instruments to achieve a better efficiency in the use of water
for irrigation. IAS provide the farmers with irrigation scheduling information, based on crop water requirements for different
crops, and thus, help farmers to optimise production and cost-effectiveness. Current IAS rely on labour- and cost-intensive
field work, yet are unable to cover each plot in large areas at regular short time intervals. Earth observation (EO) is naturally
destined to fill this gap. It allows for efficiently monitoring crop water requirements and related parameters within each
field in extended areas. The incorporation of IT in the generation and distribution of information makes that information
easily available to IAS and to its associated farmers in a personalised way. Farmers can opt to receive a wide variety of
products, tailored to their needs and infrastructure, ranging from simple irrigation scheduling recommendation (irrigation
volume, time) to colour-coded images (providing quick intuitive information on the crop vigour within their plots), both on
PC and/or mobile phones.
This work is based on the project DEMETER (DEMonstration of Earth observation TEchnologies in Routine irrigation advisory
services), which assesses and demonstrates the EO- and IT-induced improvements in IAS day-to-day operations. This paper describes
the methodology and discusses examples of products. |
