Unploughed fields take edge off heatwaves
‘No-till’ farming — in which seeds are sown into fields without first ploughing them — could help to lower temperatures near croplands by up to 2 °C, researchers report in the Proceedings of the National Academy of Sciences. Read more.

Hong Kong Hydroponics Farm Owner Cuts Energy Costs by 25% in his Greenhouse
Henry Ngai Hon-shun, owner of 0.27 hectare hydroponics farm in Hong Kong decided to opt on a solar power to slash his carbon footprint and energy costs by a quarter in his greenhouse. His action comes after warnings from the government that an increase in electricity demand will force prices to rise. Read more in Soilless Newsletter

USDA Helps Landowners Manage for Soil Health & Buffer Drought Effects
Two farms have the same soils, same crops and same precipitation. The difference is that one farm uses many conservation practices that help improve soil health helping it thrive through extreme weather conditions (read more). Soil health is always important, but extreme weather in the last few years has shown landowners just how important managing for it really is. "The vital part of soil is topsoil, which unfortunately is also the part most susceptible to the effects of weather. That’s what makes protecting it so crucial,” said Doug Miller, soil health coordinator with USDA’s Natural Resources Conservation Service (NRCS) in Minnesota.
One percent of organic matter in the top 150 mm of soil can hold about 250 litres of water per hectare. Increasing organic matter increases the holding capacity for water making your land more resilient to extreme weather. NRCS identified four principles that help improve soil health: 1. Keep soil covered as much as possible. 2. Use plant diversity to increase diversity in the soil. 3. Keep living roots in the soil as long as possible. 4. Disturb the soil as little as possible. Managing for soil health can help increase productivity and profits, decrease inputs and improve sustainability for farms and ranches. NRCS has more information on drought resources and soil health. Also, complete information on drought and disaster resources is available on the USDA website.

Fungi may determine the future of soil carbon.
When scientists discuss global change, they often focus on the amount of carbon in the atmosphere and vegetation. But soil contains more carbon than air and plants combined. This means that even a minor change in soil carbon could have major implications for the Earth's atmosphere and climate. New research by Smithsonian Tropical Research Institute scientist Benjamin Turner and colleagues points to an unexpected driver of soil carbon content: fungi. Read more.

Agriculture Leaders Announce a Partnership to Promote Conservation Agriculture Adoption
UN highlights role of farming in closing emissions gap
Matt McGrath (BBC News Environment correspondent) reports that the UN says that changing farming practices could play an important role in averting dangerous climate change. In their annual emissions report, they measure the difference between the pledges that countries have made to cut warming gases and the targets required to keep temperatures below 2C. On present trends there is likely to be an annual excess of 8 to 12 giga-tonnes of these gases by 2020. Agriculture, they say, could make a significant difference to the gap, including wider adoption of conservation agriculture.CGIAR Water, Land & Ecosystem Blog Space

Cover crops work. That's the message from the results of a recent study. Last year's drought gutted corn and soybean yields. But that yield hammer was much lighter on those crop acres that were preceded by a cover crop. The study, conducted by the USDA North Central Region Sustainable Agriculture Research and Education (SARE) program and Conservation Technology Information Center (CTIC), sought opinions from more than 750 farmers in the Corn Belt on cover crops, how widely they're adopted, their payback and challenges.

Partnering for improved food security, a better environment and regional development
May 2013 – Updates and Hottest Issues
The two weeks training-cum-study tour on Farm Mechanization for African Stakeholders was carried out under the auspices of The Farm Mechanization & Conservation Agriculture for Sustainable Intensification (FACASI) project with the objective to identify opportunities to transfer Indian technologies and Indian expertise to Africa.
Thedelegation comprises participants sampled from private sector players(importers, manufacturers); researchers; academia; and non-governmental organizations – all stakeholders to the FACASI project. These included participants from Ethiopia (4), Kenya (4), Tanzania (4), Zimbabwe (3), Regional (ACT), and the CIMMYT FACASI project Coordinator. Highlights of the trip are:
The Indian Universities have been effectively linking manufacturers, importers and farmers; acting as hubs for technology development.
India has a manufacturers’ association with a political voice which can/does influence policies in favour of the industry.
Developed technologies are effectively extended to farmers through scaling out models including farmers’ cooperatives sometimes specialised in mechanised equipment hire services.
Research focus - to concentrated action centres/zones and areas of excellence such as soil sodicity /salinity - is a key driver to the successful introduction of sustainable agriculture.
Government support to farming is very strong in India. Examples include: free electricity (for pumping irrigation water in the 2 states); VAT exempt on machinery; subsidies on mechanization and irrigation equipment; and government purchase of farmers’ produce at profitable prices.
It is argued that that the Indian Green Revolution took place only in the Punjab and Haryana States! What does Africa have to learn from this knowledge?
ICAR is desirous to further the south-south collaboration for the longer-term mechanization of farming in Africa. The leadership of CIMMYT & ACIAR through FACASI comes at an opportune time.

14. Up-dating Conservation Agriculture Data Base in AquaStat, FAO
The CA land area data base is updated periodically based on the feedback received from our regular sources of information and is posted in AquaStat. The latest figures can be seen at the FAO CA-Website at (http://www.fao.org/ag/ca/6c.html).
We are updating the CA land area data base displayed in AquaStat (www.fao.org/ag/ca), and are contacting our regular sources of information in the next few weeks. However, anyone else who would like to provide information on the land area under CA systems at the national level would be most welcome.
Ideally, we would appreciate receiving from you the CA area information at the sub-national level (by state, province or region), together with any relevant historical information on adoption (such as when was CA introduced; duration under CA – x ha under 3 yrs, y ha between 3 and 6 yrs, z ha more than 6 yrs), cropping pattern, farm size, agro-ecology, constraints, etc.
For the recording purpose please adhere to the reference 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 for seeding 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. Area under strip tillage can be included only if the disturbed area is less than the above set limits.
2. Maintenance of organic soil cover: Three categories are distinguished: 30-60%, >60-90% and >90% ground cover, measured immediately after the direct seeding/planting operation. For this data base, area with less than 30% cover is not considered as being under CA.
3. Crop rotation/association: Rotation/association should involve at least 3 different crops. However, repetitive wheat or maize or ricecropping that meets requirements 1 and 2 above 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).No-till area by crop will not be recorded to avoid double recording of the same land area.
Area under perennial crop systems including orchards and permanent pastures will be recorded separately. If there is CA land area under perennial crop systemsin the country, please include the information as separate categories at the sub-national level (by state, province or region), together with any relevant historical information on adoption (such as when was CA introduced; duration under CA – x ha under 3 yrs, y ha between 3 to 6 yrs, z ha more than 6 yrs), cropping pattern, farm size, agro-ecology, constraints, etc.
