The third offering of the advance course-Asia “Conservation Agriculture:
Gateway for Productive and Sustainable Cropping Systems” began at Punjab
Agricultural University (PAU), Ludhiana, India, on 28 May 2012. The
advanced, two-week course (May 28-June 9) was organized jointly by CIMMYT,
the Cereal Systems Initiative for South Asia (CSISA) Punjab Hub, and PAU.
Participants came from backgrounds in agronomy, soil science, engineering,
plant breeding, and plant pathology, and included representatives from
Iran, Afghanistan, China, Bangladesh, and India. More information available
in CIMMYT e-informa 1799, 15-22 June 2012.

*26. **Up-dated Conservation Agriculture Data Base in AquaStat, FAO *
The CA land area data base has been updated based on the feedback received
from our regular sources of information and has been posted in AquaStat.
The latest figures can be seen at the FAO CA-Website at (
http://www.fao.org/ag/ca/6c.html).
However, updating of the data base is an ongoing process, and anyone who
would like to provide information on the land area under CA systems at the
national level is most welcome to do anytime. Ideally, we would appreciate
receiving the CA area information at the sub-national level, together with
any relevant historical information on adoption, cropping pattern, farm
size, agro-ecology, constraints, etc.
For the recording of area under CA, please adhere to the quantification of
the CA definition on the FAO-CA website: http://www.fao.org/ag/ca/6c.html
*1. Minimum Soil Disturbance: Minimum soil disturbance refers to low
disturbance no-tillage and direct seeding. The disturbed area must be less
than 15 cm wide or less than 25% of the cropped area (whichever is lower).
There should be no periodic tillage that disturbs a greater area than the
aforementioned limits. Strip tillage is allowed if the disturbed area is
less than the set limits.*
*2. Organic soil cover: Three categories are distinguished: 30-60%, >60-90%
and >90% ground cover, measured immediately after the direct seeding
operation. Area with less than 30% cover is not considered as CA. *
*3. Crop rotation/association: Rotations/associations should involve at
least 3 different crops. However, repetitive wheat or maize cropping is not
an exclusion factor for the purpose of this data collection, but
rotation/association is recorded where practiced.*
*We would further like* to stress that the database counts actual land area
under annual crops with CA (permanent no-till). Area under perennial crops
will be recorded separately. No-till area by crop will not be recorded to
avoid double recording of the same land area.* ***
