Rains Threaten Promise of Good Harvest

Friday, October 30th, 2009

By David L. Brown

We remember with a shudder the spike in food prices last year that seemed to push the world toward famine. As the U.S. is one of the few remaining exporters of food in the world, the harvest here is pretty important. And, thanks to plenty of rain during the growing season, 2009 was looking like a great season for corn and soybeans across the farm belt.

Just three weeks ago, on October 9, the Dept. of Agriculture issued a news release predicting an excellent harvest of corn, soybeans and other crops. Here is what the USDA news release (read it here) had to say about corn and beans:

Corn production is forecast at 13.0 billion bushels, up 8 percent from last year and down only 0.2 percent from the 2007 record. Corn yield is expected to average 164.2 bushels per acre, up 10.3 bushels above last year. If realized, this yield will be the highest on record. Corn growers are expected to harvest 79.3 million acres, down 1 percent from the September forecast.

Soybean production remains on target for a record-high year and is forecast at 3.25 billion bushels, up 10 percent from 2008. Based on October 1 conditions, soybean yields are expected to average 42.4 bushels per acre, up 2.7 percent from 2008. If realized, this will be the third highest yield on record. Growers are expected to harvest 76.6 million acres of soybeans, which is the largest area on record.

10-29-09_18281Pretty good news, right? But what a difference three weeks can make. I am reminded of the old saying: “Man Plans, God Laughs.”

It seems that things are not going too well in this harvest season. Many crops were planted late due to excessive Spring rains, or replanted because of flooding. Now the harvest is running late and the rains have returned to keep farmers out of the field, or to create disasters if they do venture forth. The picture at left tells the story. It was taken yesterday in Clark County, Arkansas.

And it’s not just in Arkansas that rainy weather has struck throughout October. Following are on-the-scene reports posted today by farmers on the AgWeb.com website (here). To give you a good feel for what’s happening right now, I’m posting nearly all of today’s comments. Here’s what farmers were saying today:

Menard County, Central Illinois: I think it is time to remind everyone (or maybe you realize) that just because there is a week of dry weather in the forecast we are actually going to be harvesting for that whole week! Around here we are probably looking at 4 or 5 good drying days before we could consider getting back in the field, and we will still be making a mess.  I also expect the Sangamon River and Salt Creek to come out of there banks today and tomorrow, affecting thousands of un-harvested acres.  I would estimate that harvest progress for this area is: corn 20% complete, soybeans 40%. What a year…good luck.

Bond County, South Central Illinois: UN-FREAKIN-BELIEVABLE.

Huntington County, Northeast Indiana: We are having RAIN for the umpteenth time this month!!  We still have 125 acres of beans to cut.  And they are really good beans.  Yielding really well.  We have shelled a very small amount of corn and it was wetter than we have dried for several years.  25-30 [percent] moisture.  We hope we have a lot of nice days in November.  Stay safe and keep smiling.

Audrain County, Mo.: Lindsey Benne, Beef Today and Dairy Today Art Director: Farmers are hauling in gravel to their fields just to get in and out.

Carlos, Minn.: It has been raining off and on for 3 weeks. We got a start to the beans 3 weeks ago, some of my neighbors were out on Tuesday the only day of full sun and wind that we had. The beans were between 18-28 %. I don’t have the balls to try that yet. I thought we could go on Wednesday but at 10 am it started to drizzle and it has been raining ever since to get through the gloom we have put the carpenter belt on to do some remolding have a safe harvest say a pray for dry weather.

Opole, Minn.: Rain, rain, go away, and come back next July day!!!

Lafayette County Wis.: WET, WET, WET. I guess we are all in the same boat. We are way, way behind. Corn is developing green mold. Broker says when weather straightens out there is a big crop out there. Problem is will the sun ever shine again?  Stay safe everyone…a safe harvest is a good harvest.

Nebraska Panhandle: Guess we don’t have to worry about the irrigated corn blowing over before harvest, the snow is holding it up!

Buena Vista County, Northwest Iowa: Raining here again, close to 10 inches now in October, Still some beans out in the fields here, I just got done, Yields decent in the 50′s which is normal. Some have gave up on beans and started corn, most of it from what I’ve heard is anywhere from 20% to 40% moisture and yields from 120 to 220, with very low test weights.  Stalk Rot now a real concern & some guys are finding green snap [broken stalks] they didn’t know they had, those yields cut in half.  I believe this harvest, when it’s over, if ever will be one, we all will want to forget!

Cass County, Iowa: 1.4 in. of rain so far today and it’s still raining. I’ve only run 80 acres of beans in October. It rains or drizzles nearly every day. Yields are great with beans 50 to 62 and most corn over 200 but wet @ 23 to 25%.  It’s going to be a long fall at this pace.

So, let us make a wild guess: The excellent harvests predicted just a few weeks ago are in big trouble, especially if the rains continue. When crops remain in the field past their “use by date,” they quickly begin to deteriorate. As some of the farmers quoted above mention, mold can damage the kernels, especially in wet conditions. Stalk rot can set in, allowing wind to blow down the mature stalks, making it impossible to harvest with a combine. (In the old days, farmers would respond to that problem by turning cattle or hogs into the fields to chow on the fallen crops … but that was in the days when most farms had livestock, and most  fields had fences.)

The world supply of food is running dangerously low, and a poor harvest in the U.S. is potentially disastrous, especially in light of severe drought conditions in Australia and northern China this season. If we go into 2010 with anything less than bin-busting yields, another world food crisis is almost certain to develop. And, as I pointed out in an essay on June 2 (here), famine doesn’t result from a shortage of money (although there is a lot of that going around), but a shortage of food. Hungry people can’t eat money, and money can’t feed hungry people when there isn’t enough food to buy.

A major weather front is now moving east out of the Midwest, bringing promise of several sunny days. However, as the farmer from Menard County, Illinois pointed out above, it takes at least four or five days for ground to dry sufficiently to get machinery into the fields. If another front moves through in a week or so, we could see another cycle of mud and gloom.

I’ll keep an eye on this unfolding threat, and, oh … could something called “climate change” have anything to do with this? Surely not.

China, India Blow Copenhagen Out of the Water

Sunday, October 25th, 2009

By David L. Brown

One of the most pleasing phrases in the human language (to the speaker, at least), is “I told you so.” Thus, my recent essay on why the upcoming Copenhagen meeting on climate change was unlikely to produce anything important is proven prescient by the following excerpt from an editorial in Investors Business Daily, posted Friday on its web site Investors.com (read it here):

Climate Change: With less than two months to go before the big Copenhagen Conference on global warming, two major nations have said “no thanks” to the no-growth agenda. For that reason alone, so should we.

Following a deal signed late Thursday between China and India, anything we might agree to do in Copenhagen is likely moot anyway. The two mega-nations — which together account for nearly a third of the world’s population — said they won’t go along with a new climate treaty being drafted in Copenhagen to replace the Kyoto Protocol that expires in 2012.

I wrote about this on October 6 in an essay titled “High Hopes for Copenhagen May Be Dashed,” and now I can afford to crow because without China and India — representing the two largest nations in population and among the fastest growing in terms of industrialization — the Copenhagen accords are unlikely to become reality. That’s especially true if, as IBD suggests, “[O]ther developing nations, including Mexico, Brazil and South Africa, will likely reject any proposals as well.”

When the Kyoto Protocol was launched in 1997, developing countries were quick to sign on because the agreement gave them a “get out of jail free card,” by exempting them from limits on CO2 and other greenhouse gas (GHG) emissions. The idea was to let the “developing” countries continue to develop while the First World nations, and most particularly the United States, were expected to fix the whole problem. The attitude was “You made this mess, you fix it. Meanwhile, it’s our turn.”

Now that it has become crystal clear that climate change is a global problem, and that developing nations may stand the most to lose, the new agreement sets forth a universal effort that would include all nations in a worldwide program to reduce GHG emissions. To which we see the interesting reaction from those who were all too eager to sign on as long as they didn’t have to do anything to slow or reform their own economies. Now, like characters in the story of the Little Red Hen, they are telling us in no uncertain terms, and in the Mandarin and Hindu equivalents: “No way, José.”

The IBD editorial concluded:

Even with their participation, Copenhagen should have been a non-starter for the U.S. Indeed, the main reason for the greenhouse gas deal, all but admitted to by its major participants, is to cripple the U.S. economy — the most successful economy in the world.

True enough, as green critics keep saying, we produce nearly 20% of the world’s CO2 and other greenhouse gases with just 5% of the world’s population. But our GDP of roughly $14 trillion is nearly 25% of the world’s total — in line with our gas output.

As I noted in my previous essay on October 6, the developing nations have attempted to re-cast the argument from a national to a per-capita measuring stick, and while that brings its own problems it’s not entirely unfair. However, a per-GDP approach might make even more sense, and as you can see on that basis the U.S. stands in pretty good stead, producing a quarter of world GDP while emitting only a fifth of greenhouse gas. One could make the argument from this that the U.S. should be allocated less stringent limits while the rapidly industrializing Chinese and Indian economies should be reined in hard. Of course, that most certainly ain’t gonna happen, thus the conclusion that Copenhagen is doomed to failure.

Of course there is the chance that in some form of national suicide in the name of political correctness, our administration might sign onto the program almost unilaterally while the developing nations head for cover. That would be a wonderful moral stand, worthy of a Nobel Peace Prize perhaps, but unfortunately should the U.S. attempt to take on its shoulders the Sisyphean task of rolling the global warming boulder back up the mountain, it will surely share the fate of the original Sisyphus, confronted by unending frustration and woe.

As has been pointed out, every barrel of oil that the U.S. does not consume, someone else will, probably someone in China or India. No matter how much we attempt to reduce GHGs, the new industrialization now running rampant in the developing nations will continue to pour CO2, methane, nitrous oxide and other gases into the air. In the end, we will have beggared ourselves for the benefit of others, and climate change will continue apace.

It is true that in the longer run, anything the U.S. does to reduce its use of non-renewable energy will benefit us. It’s hard to argue about that, but the problem is that the reward is on the other side of a  wide and yawning Grand Canyon of economic cost and commitment, and with the present state of affairs and declining resources, it will be a very difficult journey indeed to get to the other side.

There is one ironic point about all this, and that is that industrial growth is naturally limited thanks to depletion of resources and  the rising costs of developing and applying them. The developing nations already are banging against this metaphorical ceiling. We have entered a yo-yo world economy that is hitting the limits to growth* due to the petroleum supply-demand situation. There isn’t enough oil, and particularly cheap and easily developed oil, to allow the world’s economies to continue to improve themselves as they have in the past through increased use of resources.

The ceiling is there, and it is real.  No matter how hard they try, those “developing” economies will keep hitting it and being knocked back Each time the world economy starts to “grow,” the cost of oil and other natural resources will rise and put on the brakes. We have seen this pattern clearly in the past couple of years, and it is not an anomaly but the new reality. For those who have been observant, the signs of this looming calamity have been apparent for decades.

In a perfect world, every government on the planet would recognize the long-term and even relatively short-term dangers of climate change and the futility of continued industrial growth. Considering the future cost to their people, they would enthusiastically join in to solve the problems before civilization is destroyed.

Reality check: This is not a perfect world. One might say, with considerable truth, that it is a very imperfect world, at least from the perspective of the human race, which seems content to turn the problem over to Nature, or Gaia. She knows what to do. She is doing it now. It will not be pretty.

• Note: “The Limits to Growth” was the title of a book published by the Club of Rome in 1972. It was one of the first clarion calls of warning about what was to occur. Now, 37 years later, we are beginning to learn the lesson the hard way. And, here’s an interesting point: In 1972 nobody even knew about global warming and climate change — that’s another confounding factor altogether, one that has assumed major importance.

Science Leaders Speak Out on Warming

Thursday, October 22nd, 2009

By David L. Brown

In advance of the upcoming Copenhagen meeting on climate change, there has been a recent tidal wave of anti-global warming propaganda. I’ve discussed the subject of climate change denial many times over the years, most recently in an essay titled “Science, Propaganda & Climate Change,” published October 4.

The cacophony of idiocy has further confused members of the public, to the extent that a new poll released today by the Pew Research Center (read their report here) revealed that:

“There has been a sharp decline over the past year in the percentage of Americans who say there is solid evidence that global temperatures are rising. And fewer also see global warming as a very serious problem — 35% say that today, down from 44% in April 2008.”

All of this flies in the face of the virtual unanimity of opinion among scientists qualified to hold serious opinions on the subject of global warming. And, sadly, many if not most members of Congress are unsure about the issues. That’s not surprising considering that most politicians are trained as attorneys and share with the majority of Americans a general lack of sound education in science. Senators and Congressmen also tend to surround themselves with staff having backgrounds in political science, fundraising, opinion polling and the like. Furthermore, Congressional offices are besieged by lobbyists for special interests whose aims often lie in the direction of climate change denial.

Apparently responding to this dismal situation, a group of leaders from major science organizations yesterday sent a letter to each member of the Senate, making the case for action on climate change. The letter is important enough, particularly in view of the powerful reputations of the organizations behind it, that I decided to reproduce it here in its entirety.

October 21, 2009

Dear Senator:

As you consider climate change legislation, we, as leaders of scientific organizations, write to state the consensus scientific view. Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver.

These conclusions are based on multiple independent lines of evidence, and contrary assertions are inconsistent with an objective assessment of the vast body of peer-reviewed science. Moreover, there is strong evidence that ongoing climate change will have broad impacts on society, including the global economy and on the environment. For the United States, climate change impacts include sea level rise for coastal states, greater threats of extreme weather events, and increased risk of regional water scarcity, urban heat waves, western wildfires, and the disturbance of biological systems throughout the country. The severity of climate change impacts is expected to increase substantially in the coming decades.

If we are to avoid the most severe impacts of climate change, emissions of greenhouse gases must be dramatically reduced. In addition, adaptation will be necessary to address those impacts that are already unavoidable. Adaptation efforts include improved infrastructure design, more sustainable management of water and other natural resources, modified agricultural practices, and improved emergency responses to storms, floods, fires and heat waves.

We in the scientific community offer our assistance to inform your deliberations as you seek to address the impacts of climate change.

What more can I add? The letter is succinct and to the point; it is written in language that even most Senators can probably understand; and it is signed by the leaders of some of the most prestigious scientific organizations in America. I can only add that I hope that this or a similar letter will soon be going to all U.S. Representatives, leaders of Washington bureaucracy from the White House down to deputy assistant secretaries at every department,  and the offices of every state governor.

Sun Continues to Show Blank Face

Monday, October 12th, 2009

By David L. Brown

This is a follow-up to my post of June 29 titled “Could Quiet Sun Offset Global Warming?” (see it here.) In that piece I reported on the failure of the Sun to return to its maximum sunspot cycle, remaining a blank and featureless orange disk. As I wrote, if we are entering a new extended minima as has happened in the past, most notably during the Maunder Minimum in the 16th and 17th centuries, it could have a significant effect on global warming. High sunspot activity actually increases the amount of heat put out by the Sun, and thus an extended minima could give us a respite from global warming, helping to offset the effects of greenhouse gases.

On July 9th I followed up with a brief item titled “Sun Begins to Show Its Spots,” reporting on the appearance oflatest-1 a rather small and unexciting outbreak of spotting. However, that seems to have been a false alarm, since the Sun quickly returned to a condition of “Code Orange.” At left is the way it appears today, plain as a billiard 5 ball (but without the number). In fact, the similarity is so exact that I thought it would be worth posting a comparison image, as at the right below

Astronomers are vexed at the Sun’s failure to return to its usual cycle of sunspots. According to the SpaceWeather.com site, which tracks the Sun on a daily basis, the number of spot free days during 2008 was the highest since 1913 — and so far 2009 has seen even fewer spots. The average number of spotless days during an average minima is 485, and in this cycle we have already obsbilliardballs5809erved 733 spot-free days with no end in sight.

The Maunder Minimum is associated with the event known as the Little Ice Age, so this is a subject we should be aware of. Of course, as global warming progresses we are in no danger of any new ice ages, little or not, but at least there may be a respite from the rising temperature. I will keep an eye on this phenomenon and make occasional reports.

High Hopes for Copenhagen May Be Dashed

Tuesday, October 6th, 2009

By David L. Brown

081204093041Great hope is being placed on the upcoming conference on climate change, to take place December 7*-18 in Copenhagen, Denmark. The meeting has the acronym COP15, which indicates it is the 15th “Conference of Parties” in the UN’s Framework Convention on Climate Change. Representatives from 170 countries are expected to take part. It is hoped that COP15 can make substantial progress toward a replacement of the Kyoto Protocol which expires in 2012.

Although there is much sturm and drang about this issue, my feeling is that any significant progress may be difficult if not impossible to achieve. The problem is that most poor or developing nations want exceptions to the need to reduce emissions of CO², methane and other greenhouse gases (GHGs), in effect pushing the problem onto the advanced nations. The general argument is that the rich nations have been the biggest polluters in the past, and that they should therefore bear the expense of fixing the problem. That particularly targets the United States, which was formerly the No. 1 source of carbon emissions. Unfortunately, in view of the present economic woes, the First World economies are not exactly robust.

Another fact to consider is that the advanced nations have already passed into what is called the Post-Industrial Age, even as developing nations are introducing into the world a new era of industrialization. Thus, the title of the world’s No. 1 source of GHGs has recently passed to China.

Identifying rich nations as the responsible culprits also flies in the face of the fact that developing countries are the main source of rising GHG emissions. For example, the amounts of carbon released by India grew by 103 percent between 1992 and 2007. China did even worse, with carbon emissions growing by 150 percent. As we’ve reported here, China is bringing nearly two coal-fired power plants on-line each week.

How do these figures relate to the global picture? Taking all nations into account, on average GHG emissions increased by 38 percent during that period. In the United States, a rise of just 20 percent was reported. Some EU member nations have done even better, with several including Germany, France and Great Britain among others actually achieving net reductions.

Now I will be the first to point out that to compare statistics in the form of percentages such as those can be extremely misleading, subject to the embarrassing question “percentage of what?” To explain by example: If you have one apple and get one more apple, you have enjoyed a 100 percent increase. A very big increase, right? But it’s relative, you see, for if you have 100 apples and get one more apple you have experienced an increase of only one percent . A very small increase—and yet in both cases the difference was precisely the same, one apple.

India and China were coming from behind, with lower bases against which to measure the increase (fewer apples), so it makes their statistics seem larger. The US had a higher starting point (more apples), thus making that increase seem smaller by comparison. Indeed, according to the World Resources Institute:

Overall, with less than one-twentieth of the world’s population (U.S. Bureau of the Census, 2009), the U.S. currently accounts for about one-fifth of total global emissions of [GHGs].

It is common sense that the world’s largest economies would be the largest sources of carbon emissions, because development has been based on fossil fuels since the beginning of the Industrial Revolution. However, the problem of GHG emissions cannot be solved by looking into the past, but by changing future actions everywhere. Unfortunately, the general drift seems to be that the majority of the world’s people, as represented by the governments of populous nations such as India and China, would like for the more advanced nations to contribute most of the hard work and sacrifice of reducing carbon emissions, while leaving the “developing” nations to continue relatively unimpeded on the course of industrialization.

Science, Propaganda & Climate Change

Sunday, October 4th, 2009

By David L. Brown

If a climate change denier wants to make a point, it seems there’s no need to worry about the facts. No, just making stuff up seems to be the policy being followed these days. As someone recently pointed out, the argumentative* model used by climate change deniers is looking more and more like the crazy ravings of Creationists, or as they like to call themselves, advocates of “Intelligent Design.”

It goes something like this: Conjure up a strawman based on some unsubstantiated “fact,” then use that to attempt to destroy the entire edifice of scientific knowledge about the subject at hand. In the case of “intelligent design,” the process is to state that, for example, it would be impossible for a certain feature of living creatures such as the eye to evolve, ergo, evolution is a hoax, Charles Darwin was the Anti-Christ, and the Earth was created 4000 years ago. Trouble is that there is no basis for the starting statement, because evolutionary biologists can quite easily explain the evolution of the eye. What seems reasonable to the uninitiated  has no basis in fact, and such processes of “reason” depend for their success upon the ignorance of the audience.

With the question of global climate change, the usual “argument” goes something like this: “It’s colder today in (fill in place) than usual, so there is no global warming.” The trouble with that utterly simplistic statement is that no climate scientists believe or have ever stated that global warming will be observed as an overall steady rise of temperatures equally spread out all around the world. In fact, the concept of “climate change” allows for and indeed predicts that some areas will grow colder (thus the stupid movie The Day After Tomorrow). It is the average temperature that is rising, not the temperature in Podunk, Minnesota where it might be colder than a… well I’ll let you complete that statement (Hint: rhymes with “which is it?).

Nowadays climate change deniers are becoming more aggressive than ever. For example, there is presently a big hoo-haw going around about the “fact” that the “hockey stick” graph made famous by Al Gore in his An Inconvenient Truth has been discredited, and in fact the world is actually cooling. Articles, blog entries, op-eds and media commentators have sprung up everywhere to trumpet this “news.” According to the general theme of the reportage, the big bad wolf of climate change is dead, we can all go back to burning fossil fuels forever, and it might be a good idea to invest in a nice warm set of woolen underwear.

The trouble is that the underlying “fact” of this “argument” isn’t true. For a complete debunking, see this analysis on the RealClimate.com web site. (Incidentally, that site has the subtitle, “Climate science from climate scientists.” Wow, what a concept!) I won’t even attempt to summarize this report and invite you to follow the link if you want to read the details, including a batch of graphs that show that the “hockey stick” still lives and there is no credible evidence for the position that it has been in any way discredited. I will share with you this graf from the RealClimate article, referring to these kinds of “kerfluffels”:

The timeline for these mini-blogstorms is always similar. An unverified accusation of malfeasance is made based on nothing, and it is instantly ‘telegraphed’ across the denial-o-sphere while being embellished along the way to apply to anything ‘hockey-stick’ shaped and any and all scientists, even those not even tangentially related. The usual suspects become hysterical with glee that finally the ‘hoax’ has been revealed and congratulations are handed out all round. After a while it is clear that no scientific edifice has collapsed and the search goes on for the ‘real’ problem which is no doubt just waiting to be found. Every so often the story pops up again because some columnist or blogger doesn’t want to, or care to, do their homework. Net effect on lay people? Confusion. Net effect on science? Zip.

One of the things that must just frost the deniers’ butts is the fact that we see glaciers receding, the oceans rising, permafrost melting and so forth. So another thing they do is to make up stories about these realities. For example, in a letter to the editor of the Orange County Register today, a certain Larry Hamlin chimes in on the subject. The author identifies himself as “former state energy czar under Gov. Gray Davis” and a retired vice president of “SCE Power,” which is the working name of Southern California Edison, the local electrical power company.

Ug99 Poised on Afghan Border

Thursday, October 1st, 2009

By David L. Brown

I have written several times over the past few years about the spreading threat of Ug99, a wheat stem rust disease first identified in Uganda in 1999. It is a serious threat not only to wheat, but also related barley and rye varieties. Spores carried by the wind have been spreading Ug99 toward the major wheat growing regions stretching from Iran through Afghanistan and the other “Stans” and eventually to India and China. All of these nations are seriously dependent upon wheat crops to support their people. This disease does more than just reduce yields—it destroys entire crops. Agronomists are struggling to find or breed resistant varieties to replace the threatened “staff of life,” the mainwheat-beautiful source of food for about a third of the world’s people from southern Europe through China. The “bounteous waves of grain” as pictured here and that provide all-important food for a third of the world’s people are under serious threat.

Now the ugly disease has reached the border of Afghanistan and is poised to enter that nation, already in a state of chaos. Afghans are dependent upon two crops, wheat and opium poppies—and you can’t live on a diet of opium, or at least not for long.

According to a recent news item in New Scientist magazine, Afghan farmers harvested a bumper crop this year, thanks to timely Spring rains. But, the article continued, “… the beleaguered country can’t rest easy. The Ug99 wheat rust, a virulent fungus that wipes out entire crops, is poised to cross the border from Iran.”

The article, which appeared in the August 8, 2009 edition, continued:

Fungal spores have been spreading on the wind from Uganda, where the disease was first discovered in 1999. They reached the wheat fields of Iran two years ago, prompting scientists to warn that millions in Asia were at risk of starvation. If the epidemic reaches Afghanistan, its effects would be catastrophic. “Nearly all farmers in Afghanistan grow wheat for food or sale,” says Mahmood Osmanzai, a scientist working for the International Maize and Wheat Improvement Center in the country. Most of the wheat varieties grown in Afghanistan, and indeed around the world, are vulnerable to Ug99.

I’ve been reporting on this threat since my first post on the subject on August 31, 2006. For more details about the threat of this “ugly” wheat disease, read earlier posts here, here, and here.

In a world besieged by climate change, a spreading disease with the ability to destroy small grain crops is the last thing we need. Australia, formerly a leading exporter of foodstuffs, has been suffering long-standing drought conditions, and the wheat growing region of China has been similarly struck with dry conditions. Waving fields of grain are being replaced by dust storms reminiscent of the Dust Bowl Days of the U.S.

Afghanistan, with a population of around 30 million, is in serious danger of famine should the wheat crop fail. World stocks of grain and other foodstuffs are at record low levels, and aid agencies and foreign governments could be hard pressed to fill the shortage in case of  a devastated Afghan wheat crop. But that is a minor problem compared with the looming threat when (not if) Ug99 spreads through Pakistan and northern India and China, where more than two billion people are heavily dependent upon wheat as “the staff of life.” These three nations rank No. 1,2 and 6 in the world by population.

There is real fear that the Ug99 strain of wheat stem rust may find its way into North America. A spreading plague of plant disease across the wheat growing regions of the U.S. and Canada could mean disaster for a world already teetering on the brink of famine.

I’ll keep watching this important subject, which seems to attract little attention from the conventional media.
