New information for agrometeorologists

Last modified September 26, 2008 09:27

Under "New information for agrometeorologists" we mention relevant new web sites (before they become only routine links), data bases, software, CDs, trends, issues and other information in agrometeorology [Send items for inclusion to the Web Editor.]

Crowdsourced Rain Samples Map Hurricane Sandy's Evolution — Last modified March 25, 2014 15:32
A unique method to collect rain water samples during Hurricane Sandy has revealed the storm's chemical "signature" with a new level of detail. The technique may also lead to weather model advances that will ultimately improve storm prediction, say researchers at the University of Utah whose study was published online today in PLOS ONE.
Crop yields have ‘largely kept pace with population expansion’ — Last modified March 07, 2014 12:00
As the world’s population has grown, considerable efforts have gone into boosting crop yields to try and feed these rising numbers. But what if crop yields had not increased in the last 50 years? How much more land would we have needed to grow crops?
As livestock eat, so they emit: highly variable diets drive highly variable climate change ‘hoofprints’ — Last modified January 10, 2014 16:16
The most detailed livestock analysis to date, published yesterday, shows vast differences in animal diets and emissions.
Biochar boosts crop yield most for weathered soils — Last modified January 10, 2014 16:13
For farmers in western Kenya, biochar is creating a stir. During scientific trials, farmers applying this special kind of charcoal to their fields found their average maize yield increased dramatically, up to double in some cases. Trials in other developing countries, including Columbia and Brazil, have had similar results. What’s more, adding biochar to soil is also thought to mitigate global warming by sequestering carbon into the soil. So is biochar the new green dream? Can it fight climate change and help feed the world, all at the same time? Possibly yes, but not everywhere, a new study shows.
By 2050 crops will feed more animals than humans — Last modified December 23, 2013 08:46
If the global population continues to grow at its current rate, and diets continue to include more animal products, by 2050 we will be growing more crops to feed animals than to directly feed ourselves, according to researchers in Germany.
Is summer on the right (storm) track? — Last modified November 07, 2013 09:02
Summer of 2013 was a glorious affair in the UK, but prior to that the nation suffered a long string of soggy summers. What turns one summer into a scorcher and another into a damp squib, and why is the UK’s summer weather so polarized? A new study shows that the fate of Europe’s summers depends on which track the storms are trammelled onto for that particular year.
Insight: agricultural models should be validated against historical data — Last modified October 11, 2013 10:03
The global population is expected to reach nine billion by 2050, requiring additional agricultural land, which in turn will have environmental consequences. But current estimates of future land requirements vary widely, in part due to the many competing factors that influence agricultural practices. Accounting for all these factors involves the use of large computational models of agriculture on the global scale; estimates from these are used to shape policies and make long-term decisions. In a study published in Environmental Research Letters (ERL), a team from Purdue University, US, has proposed a way to enhance the scientific credibility of land-use projections by validating their agricultural models against historical data
Traditional practices by farmers to improve agricultural production – Indian experience — Last modified September 27, 2013 14:16
Farmers bear the consequences of their decisions. For some farmers it is not just an issue of profit and loss, and resource management, but they must also grow enough food to feed their family and livestock.
Tropical forest carbon absorption may hinge on an odd couple — Last modified September 19, 2013 08:22
A unique housing arrangement between a specific group of tree species and a carbo-loading bacteria may determine how well tropical forests can absorb carbon dioxide from the atmosphere, according to a Princeton University-based study. The findings suggest that the role of tropical forests in offsetting the atmospheric buildup of carbon from fossil fuels depends on tree diversity, particularly in forests recovering from exploitation.
Spread of crop pests threatens global food security as Earth warms — Last modified September 16, 2013 11:27
A new study has revealed that global warming is resulting in the spread of crop pests towards the North and South Poles at a rate of nearly 3 km a year.
