survey was 1.77 Mha, while it was estimated that more than 3 Mha were micro-irrigated worldwide
by the year 2000. The decade - 1990-2000 witnessed a quantum leap in adoption of micro irrigation
technology, both in developed and developing countries.
The Working Group on On-Farm Irrigation Systems (WG-ON-FARM) at its 3
rd
meeting held at Cape
Town, South Africa in October 2000, agreed to prepare a Questionnaire for 4
th
survey on Worldwide
Usage of Micro and Sprinkler Irrigation.
The enclosed Questionnaire is based upon that used in the 3
rd
survey of micro irrigation. Considering the
new developments in micro and sprinkler irrigation technologies, the 4
th
Questionnaire has been revised
and expanded.
All the National Committees/Committee of ICID are requested to fill up the questionnaire by latest
information, as accurately as possible. It is proposed to compile and publish the information collected
through Questionnaire for benefit of all concerned. Please return the filled-in questionnaire to the Central
Office, ICID at the earliest. For any clarification, please do not hesitate to contact the Central Office.
Looking forward to co-operation from all National Committees/Committee of ICID.
