*for sustainable agriculture and land management*
Dear Subscribers,
Please see herebelow a message from John Landers in Brazil regarding his
article dealing with CA-based rice-wheat system in the Indo-Gangetic Plains
and the albedo effect (cooling) of rice straw and impact on reducing global
warming..
Thank you John for sharing.

*Conservation Agriculture is an ecosystem approach to regenerative
sustainable agriculture and land management based on the practical
application of context-specific and locally adapted three interlinked
principles of: (i) Continuous no or minimum mechanical soil disturbance
(no-till seeding/planting and weeding, and minimum soil disturbance with
all other farm operations including harvesting); (ii) permanent
maintenance of soil mulch cover (crop biomass, stubble and cover crops);
and (iii) diversification of cropping system (economically, environmentally
and socially adapted rotations and/or sequences and/or associations
involving annuals and perennials, including legumes and cover crops), along
with other complementary good agricultural production and land management
practices. Conservation Agriculture systems are present in all continents,
involving rainfed and irrigated systems including annual cropland systems,
perennial systems, orchards and plantation systems, agroforestry systems,
crop-livestock systems, pasture and rangeland systems, organic production
systems and rice-based systems. Conservation Tillage and Minimum Tillage
are not Conservation Agriculture, and nor is No-Till on its own *(more at:

Dear Amir,
You might like to circulate my discussion paper on puddling. I believe Zt
rice/wheat to be at take-off stage in the Indo-Gangetic plains. But even
more important, I flagged here the albedo effect of rice straw- this
cooling effect of increased albedo has been totally sidelined in the debate
on Global Warming and the impact of 100% ZT Rice/Wheat could be HUGE if
adopted widely in the sub-continent. It would significantly reduce globsl
warming, cut irrigation water demand and improve yields. It is a
win-win-win scenario waiting to be unveiled.
This should be an FAO project!
