Sentences with phrase «impact wheat crops»

Not exact matches

Planning meetings for the Global Seed Vault in Norway spawned the idea of looking at average summer temperatures, which climate models can project relatively reliably and which have a large impact on crop yields — between 2.5 and 16 percent less wheat, corn, soy or other crops are produced for every 1.8 — degree F (1 — degree C) rise.

This disease can have a great impact on wheat production in Europe, including organic crop production in Denmark.

A paper recently published in Crop Science examines connections between fructans in wheat plants, wheat - based food products, and impacts of fructan consumption on human health.

The weather impact on China's wheat crop will make it harder for Beijing to maintain self - sufficiency in grains.

Dr. Shabala and his colleagues note that recent research on salt bladders creates the exciting possibility of modifying genes in traditional crops such as wheat or rice to allow them to develop salt bladders without a major impact on their growth and yield.

Climate change impact analyses typically project increasing pest survival and crop damage with increasing temperatures (e.g., NCA 2014a), and wheat stem sawfly (WSS) may well be generally consistent with that pattern, but the following caveats help to show why generalizations across all landscapes in Montana, for all insect pests, are risky.

We focus instead on one major insect pest --- wheat stem sawfly (Cephus cinctus Norton)-- on Montana's dominant crop, wheat, to illustrate the mechanisms and principles involved in assessing climate change effects on agricultural pests and their impacts on crop yield or quality.

Essentially, big agra has hybridized wheat heavily over the last 5 decades to improve things such as crop yield and baking characteristics, but never once thought about the impacts on human health of changing the biochemical structure of wheat.

This topic looks at how wheat is grown in the UK through the year and the different factors, such as weather, and the decisions made by the farmer can have an impact on the success of the harvested crop.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

Without adaptation, local temperature increases of 1 °C or more above pre-industrial levels are projected to negatively impact yields for the major crops (wheat, rice, and maize) in tropical and temperate regions, although individual locations may benefit (medium confidence).

The Mail on Sunday says the Summary warns of negative impacts on crop yields, with warming responsible for lower yields of wheat, maize, soya and rice.

Crops already impacted include the main staple wheat, which is deficient in size and weight and failing to accumulate optimum starch content, the report says.

In fact the Summary says that negative impacts of climate change on crop yields have been more common than positive impacts, with wheat and maize yields negatively affected in many regions and effects on rice and soybean yields smaller in major production regions.

Other major climate impacts at 2 degrees Celsisus include severe threats to coral reefs across the globe, a greater risk of long lasting heat waves and extreme rainfall events, and the risk of lower yields for key crops like wheat in the globe's tropical regions.

Relative rainfall reductions were amplified 1.5 — 1.7 times in dryland wheat yields, but the impact was offset by steady increases in cropping area and crop water use efficiency (perhaps partly due to CO2 fertilization).

Atmospheric pollutants may impact India's major crops like wheat and rice more than temperature rise, says a new study based on a «regression model» that predicts future events with information on past or present events.

To better assess how climate change caused by human greenhouse gas emissions will likely impact wheat, maize and soybean, an international team of scientists now ran an unprecedentedly comprehensive set of computer simulations of US crop yields.

Potential crop failure due to drought led China to buy wheat on the international market and contributed to a doubling of global wheat prices; the resultant price spikes had a serious economic impact in Egypt, the world's largest wheat importer, where bread prices tripled.

These are incorporated based upon prior work using (1) the surface ozone response to methane emissions changes from two global composition - climate models, (2) the impact of ozone on yields of four staple crops, wheat, maize, soy and rice, based on the methodology of Van Dingenen et al. (2009), and (3) their valuation using world market prices, as described in Shindell et al. (2012a).
