IRRIGATION
POTENTIAL REALISED |
Brief definition |
Ratio between
irrigated land and irrigable land |
Unit
of measure |
% |
2. Position
within the logical framework DPSIR
Type of Indicator |
Driving Force

3. Target and
political pertinence
Objective |
The purpose
is to show the amount of actual irrigation water use in the
area where there is irrigation equipment. |
Importance
with respect to desertification |
This indicator
shows to what extent irrigation water resources are available,
actually used or (for many reasons) not used. In many areas
there are irrigation infrastructures but, due to reduction in
water availability, it is not used for agriculture anymore. |
International
Conventions and agreements |
The UNCCD emphasizes
the development of sustainable irrigation programmes for both
crops and livestock as a measure to prepare for and mitigate
the effects of drought. |
Secondary objectives
of the indicator |
The indicator
has political relevance and reflects the arising conflicts in
the use of water resource. |
4. Methodological
description and basic definitions
Definitions
and basic concepts |
Irrigated
area is defined as an area equipped with hydraulic structures.
Irrigable land is "Arable land under a specific plan for
which water supply is or can be made available and which is
(planned to be) provided with irrigation, drainage, flood protection,
and other facilities necessary to sustain irrigation."
(USBR Land Suitability for Irrigation) |
Benchmarks
Indication of the values/ranges of value |
Trend |
Methods of
measurement |
Irrigated area
(area equipped with hydraulic structures) divided by irrigable
land |
Limits of the
indicator |
The indicator
value does not capture the reasons that can effectively condition
the use of water resources. |
Linkages
with other indicators |
Water
leakage, Irrigated area,
Standard gross income. |
5. Evaluation
of data needs and availability
Data required
to calculate the indicator |
Data on irrigated
land and irrigable land. |
Data sources |
Regional and
National Agencies involved in the managing of water resources
(i.e. Authority of Basin in Italy). |
Availability
of data from national and international sources |
Recent
data are available at the country level in FAO's AQUASTAT (1994/1995)
which is directly based on official national data. Data are
also available from national sources in some countries only.
The data are estimated by countries at various periods and are
then interpolated. Data from 1970s are available as part of
country statistics in WAICENT |
6. Institutions

of Basilicata |
Other
contributing organizations |
Universities
of Athens, Lisbon, Murcia. |
