Paul Ehrlich wrong again: World Cereal Production Set To Reach Historic High

There’s a surging current of alarm that we’re headed for a food doomsday by 2050—that the world’s food-producing capacity will crash before population peaks at 10 billion. Don’t you believe it! Smart technology and better management policies will let us feed the hungry hordes to midcentury and beyond. —IEEE Spectrum, Summer 2013

World total cereal production is forecast to increase by about 7 percent in 2013 compared to last year, helping to replenish global inventories and raise expectations for more stable markets in 2013/14, according to the latest issue of the UN Food and Agriculture Organization’s quarterly Crop Prospects and Food Situation report. —Food and Agriculture Organization of the United Nations, 11 July 2013

Africa’s economy is growing faster than any other continent, according to the African Development Bank (AfDB). A new report from the AfDB said one-third of Africa’s countries have GDP growth rates of more than 6%. The continent’s middle class is growing rapidly – around 350 million Africans now earn between $2 and $20 a day. The AfDB’s Annual Development Effectiveness Report said the growth was largely driven by the private sector, thanks to improved economic governance and a better business climate on the continent. —BBC News, 11 July 2013

After nearly a decade of drought, Israel has decided to make its freshwater rather than wait in vain for enough of it to fall from the sky. The Sorek desalination plant opening next month will be the largest facility of its kind in the world. Once it’s operational, Israel’s four desalination plants will be capable of producing 60 percent of the country’s freshwater. There’s speculation that the country will soon see a water surplus, something that was almost unthinkable during the arid 2000s. –Walter Russell Mead, Via Meadia, 30 May 2013

Humans may never have to worry about the supply of fresh water again. The University of Texas at Austin reports that some of the university’s scientists have found a new way to desalinate sea water, potentially easing concerns over one of the crises facing human civilization we’ve been told is just around the bend. –Walter Russell Mead, Via Meadia, 13 July 2013

Thanks to The GWPF and Dr. Benny Peiser for that roundup.

Compare that news to the gloom and doom of Paul Ehrlich from juts a few months ago:

Contemplating Collapse

by Paul Ehrlich

It’s been three months since Anne and I summarized our views on this topic for the Royal Society, and we’ve been pleased that it has generated a fair amount of discussion and particularly, invitations to share our take on the future in various forum in the U.S., Australia, and New Zealand.  So far the paper has not elicited any significant attacks, save one “rebuttal” based on climate denial that was rejected by a journal.  But it has also not yet generated some of the discussion we might have hoped for, especially on key issues such as how to buffer the global agricultural system against global change so as to retain a real possibility of at least maintaining today’s nutritional situation and steps that need to be taken to increase human security against vast epidemics (such as that which now may be threatened by the H7N9 “bird flu” virus).

Ehrlich’s views have been proven wrong. Updating does not change that fact. But the IEEE (international electrical and electronic engineering) is hardly an authority either on future food security. Their article, which I studied carefully, is nothing more than a pastiche of current anecdotes that does not even begin to deal with the longer term food issues. Worse than most CAGW nonsense. This article obviously could not get published in journals traditionally dealing with agricultural topics.
Just because it’s conclusions might accord with the worldviews of many AGW sceptics does not make it right. It is actually very wrong. Detailed specifics can be found in the food, water, (and climate impacts on both) chapters of Gaia’s Limits.
Bottom line, irrigation has reached limits, best practice limits (feetilizer, planting types and practices) are being reached for some (not yet all, e.g. Rice) crops, intensification limits have been reached for most important crops (wheat, rice, alfalfa, potatoes, sorghum, taro…). Corn, soybeans, and vegetables are the notable intensification exceptions to date. And, some recent crop intensification practices are threatened by reversals from Darwinian pest evolution (best and most worrisome example being Ug99 wheat rust).
Even the optimistic FAO explicitly does not see any present way forward to feed its projected 2050 population, save some hoped for not yet in evidence miracle. A more detailed analysis shows feeding projected 2050 popularion is just possible under a specific set of limiting assumtions (lower average daily calories than at present, no growth in certain meat proportions, unlimited ‘virtual water’) but represents a fairly certain ‘soft’ limit on global population at boutmthatntime and population.
IMO Best this site stick to its expertise, climate, rather than air ill informed biases on fundamentally different topics.

Paul Ehrlich, the definitive alarmist … but only in our lifetimes because he is merely a modern day clone of the alarmists of centuries ago blaming all ills of the moment like earthquakes, floods, droughts, plagues, crop failure, fire and ice on a comet in the sky or God’s wrath and sacrificed a hundred oxen and friars.
The word “Science” should never appear in the same sentence as “Paul Ehrlich”, except for purposes of drawing a stark contrast, like this one. They are antonyms, polar opposites.
Paul Ehrlich is no different than the kooks we used to see around Times Square and Bryant Park wearing sandwich boards that proclaimed: “The End Is Near. Repent!“. He is also a symbol of the state of decay of higher education in the USA, naturally granted tenure to ensure his continual ridiculous prophecizing with no possible accountability.

To some extent you are correct however you are leaving out the most basic principle. If left alone to get on with it mankind is highly innovative and quite capable of coming up with methods for growing food yet undreamed.
When ever someone says something like this I think of the old woman I met in the 1970’s. During her lifetime she saw the USA go from horse drawn wagons and outhouses to space travel and computers. It is only the greedy and the envious and the Luddites they are manipulating that hold mankind back from a decent standard of living. Worse it is done intentionally.

Following your own logic, you should therefore not be offering others advice. Rather you should stick to climate.
As to the expertise of readers on this site, I expect more than a few are like myself. I found that Climate Doctrine was at odds with the findings in my own areas of expertise. I tried to make this information public on sites like Real Climate and was shouted down, censored, and not allowed even the basic fundamentals of reasoned argument and debate.
And I asked myself why? Why if the science is settled, if the researchers are so certain of their results, why would they act in this fashion to prevent reasoned debate. That is not how science works. So I researched the question and found the answer. Climate Science is not a science. No true science needs to include the word “science” in its name.
Climate Science is a cult, a belief system, a religion dressed in the trappings of science. It is a high priest, wearing a lab coat, carrying a clip board. Any time something happens to fit the belief, that is proof of the belief. Every time something happens to contradict the belief, that is evidence that change is just around the corner, and with this change will come even more proof of the belief.

Most American farmland’s nutrient content is, I believe, well-maintained by planting nitrogen (or other nutrient)-replacing cover crops in the off-season, crop rotation, and or fertilizing. It is the “organic” and “sustainable” divisions of the Fantasy Science Club who falsely mischaracterize mainline farming as less healthy (along with their cohorts in the “no gene splicing/Franken food” flummadiddle chapter). Most farmers with farms of any size in this valley have bachelors degrees (or at least one of their kids do) in Agriculture from W.S.U. (Wash State) or O.S.U. (Oregon State) (or have the Envirostalinists taken over O.S.U., Jim S.?). They learn the hard science of farming.
About a year ago, I had an annoying conversation with my friend who is, sadly, a brainwashed member of the “Sustainability” [Translation: requiring no CO2 emissions, since we are just about to run out of fossil fuels AND CO2 is killing the planet, don’t you know!] Division of the Fantasy Science Club (among other divisions, alas; the most tragic membership was, in my view, her joining the Paul Ehrlich Don’t-Have-Kids-to-Save-the-Planet Cult, so, she and her husband didn’t — not that choosing to not have kids is ALWAYS a tragedy, just that for that particular reason it is very sad). Anyway, my friend had the bright idea that she would start a consulting business “helping farmers.”
“Helping farmers? How?” I asked.
“By telling them how to farm with less water and less damage to the environment and, well, sustainable farming methods,” she replied fervently.
“But, there is plenty of water and those farmers are all well-educated in the latest farming science,” I said slowly, “it’s not like it was back in the 1920’s or something.”
Silence. Change of subject. Guess she decided she’d better go attend one of the meetings of the brethren before she tried again to make a convert.
And they do try. Have you noticed this? ANY chance they get, the few libs I have a chat with now and then try to convert me to the AGW cult. I encountered one in the plant section of Fred Meyer last May. “…. and have you noticed how HOT it’s been? I can hardly keep my plants watered.” We had had about 3 days of temperatures in the upper 70’s/lower 80’s F. — after which, it started raining again.

Rud,
Have you even paid attention to recent population trends on a global level? By 2050, no one will be talking about a “population bomb”, anymore. Heck, Japan and Russia are already losing population. Europe’s population will be down a quarter from where it is now. The US will more than likely fall below 300 million by 2050 (that is unless it can find tens of millions of fertile immigrants). Even Mexico and South America have birth rates at or below replacement levels. China is a demographic time bomb, and India’s population growth rate has peaked.
The problem of population and food by 2050 will not due to over farming or over population.

>>>>>>>>>>>>>>>>>>>>
Actually not. Cover crops cost money (White Dutch Clover and Korean Lespedeza is ~ $200/50lbs) and time and effort so it is often not done especially on rented or commercial farmland.
My farm lost over two foot of top soil and is now down to pure clay (98% per soil analysis), that is why it was sold. Fertilizers do not put back the micro-nutrients. or organic matter. I notice that fire ant mounds on my farm were surrounded by much greener, lusher grass which may indicate nutrients deep in the soil had been brought to the surface by the ants. I also found switching from a livestock salt block (mainly NaCl) to loose mineral salts had a significant effect on my livestock. Less grain was needed to keep condition, coat color became more intense and did not fade as much in the sun and less worming was needed across three different species, horse, sheep and goat. All three species have coat colors of white, black and various shades of brown.

The Micronutrient and Trace Element Status of Forty-Three Soil Quality Benchmark Sites in Alberta:
Abstract
Soil samples from the Alberta Environmentally Sustainable Agriculture (AESA) Soil Quality Resource Monitoring Program Benchmark Sites were analyzed for 30 micronutrients and trace elements. The broad scan of micronutrient and trace elements provides useful baseline information regarding the variability and range of element concentrations within ecoregions, soil types and landscapes. This report describes the influence of ecoregions, soil properties and historic management practices on boron (B), chloride (Cl), cobalt (Co), molybdenum (Mo), nickel (Ni), silicon (Si), chromium (Cr), cadmium (Cd) and selenium (Se). Significant differences between ecoregions were found in the o-15 cm soil samples for the elements B, Cd, and Mo, as well as for Cd in the 15-30 cm depth. Slope position had a significant effect on B, Ni, Co, Si, Cd and Se; and in most instances the highest values occurred in the lower slope position. Significant (p>0.05) differences between other elements and selected soil properties were found for B, Mo, Ni, Co, Cd and Se. Management did not appear to have an impact on the micronutrients and trace elements, although management practices that influence soil organic matter could influence some elements. No evidence of toxic levels of B, Mo, Cr or Cd was noted at any of the benchmark locations, although Ni may have the potential of causing phytotoxicity at one site. Many of the sites may deficient in Cl for crop production and low Se may be an issue for livestock production at some of the locations. Further investigation, including plant tissue analysis is recommended at some sites for the elements Ni, Si, Cr, Cd and Se. The literature does not provide well-defined criteria for determining deficiency or toxicity for many trace elements. While there was limited information for some of the elements, the extraction methods utilized were different from methods used in this study, making comparisons difficult. Sampling the upper, mid and lower slope positions at each of the sites provided valuable information on the distribution of the elements within the landscape. Micronutrient and trace element analysis of some crop samples would provide useful supplemental information for interpreting the soil data.

In other words no one has really bothered to really look at micronutrients except in livestock.

MICRONUTRIENTS IN GRASSLAND PRODUCTION
Abstract
Micronutrients, also known as trace minerals, which chiefly include boron (B), molybdenum (Mo), copper (Cu), zinc (Zn), manganese (Mn) and iron (Fe), are required in extremely small quantities by crops and livestock. Their name, however, is not meant to imply their role is minor. Their lack, e.g., can cause serious crop production problems in forages and health disorders in livestock. This presentation includes the response of forage legumes and grasses to micronutrients, their deficiency and sufficiency levels in forages and their sufficiency levels in livestock. Forage legumes are more responsive to micronutrients, particularly B and Mo, than grasses. There are fewer documented cases of Cu, Fe, Mn and Zn deficiencies than of B and Mo deficiencies in forages. Soil acidity is one of the primary factors affecting the availability of micronutrients to forages. Low soil pH, e.g., is the principal cause of Mo deficiency in soybeans in Brazil and in a variety of crops in eastern Canada. More often soil properties and environmental factors are more important than actual soil levels, in affecting micronutrient availability. Micronutrient deficiencies have been emerging as a major problem in intensively cultivated soils in many countries and have become one of the serious constraints to crop productivity. Deficiency symptoms for most micronutrients appear on the young leaves at the top of the plant, because most of these nutrients are not readily translocated. However, Mo is an exception in that it is readily translocated, and its deficiency symptoms generally appear on the whole plant. Toxicity symptoms, on the other hand, for most micronutrients appear on the older leaves of the plant which is very striking, e.g., for B. Soil, foliar and seed applied methods of micronutrient application to control their deficiency are discussed in detail. Frequently the Cu, Fe, Mn, Zn and Se levels in forages which are sufficient for optimum crop yields are notadequate to meet the needs of livestock. Selenium is a trace mineral which is not required byplants and maximum forage yields can be obtained on soils with very low amounts of soil Se.However, if animals are fed forage with low Se, they could suffer from serious muscular disorders and other diseases. White muscle disease caused due to Se deficiency is the most common disorder and is found in calves and lambs. Sufficiency levels of micronutrients for crops have been discussed in relation to the animal requirement.

EVIDENCE FOR MICRONUTRIENT LIMITATION OF BIOLOGICAL SOIL CRUSTS: IMPORTANCE TO ARID-LANDS RESTORATION
…Restoration of biological soil crusts (BSCs) may have an important role to play in the reversal of desertification due to their ability to decrease erosion and enhance soil fertility. To determine if there is evidence that lower fertility may hinder BSC recolonization, we investigated the hypothesis that BSC abundance is driven by soil nutrient concentrations. At a regional scale (north and central Colorado Plateau, USA), moss and lichen cover and richness are correlated with a complex water–nutrient availability gradient and have approximately six-fold higher cover and approximately two-fold higher species richness on sandy soils than on shale-derived soils. At a microscale, mosses and lichens are overrepresented in microhabitats under the north sides of shrub canopies, where water and nutrients are more available. At two spatial scales, and at the individual species and community levels, our data are consistent with the hypothesis that distributions of BSC organisms are determined largely by soil fertility. The micronutrients Mn and Zn figured prominently and consistently in the various analyses, strongly suggesting that these elements are previously unstudied limiting factors in BSC development. Structural-equation modeling of our data is most consistent with the hypothesis of causal relationships between the availability of micronutrients and the abundance of the two major nitrogen (N) fixers of BSCs. Specifically, higher Mn availability may determine greater Collema tenax abundance, and both Mn and Zn may limit Collema coccophorum; alternative causal hypotheses were less consistent with the data. We propose experimental trials of micronutrient addition to promote the restoration of BSC function on disturbed lands. Arid lands, where BSCs are most prevalent, cover 40% of the terrestrial surface of the earth; thus the information gathered in this study is potentially useful in many places worldwide. http://www.esajournals.org/doi/abs/10.1890/04-1959?journalCode=ecap

That paper led to:

Effects of water additions, chemical amendments, and plants on in situ measures of nutrient bioavailability in calcareous soils of southeastern Utah, USA
Abstract
We used ion-exchange resin bags to investigate effects of water additions, chemical amendments, and plant presence on in situ measures of nutrient bioavailability in conjunction with a study examining soil controls of ecosystem invasion by the exotic annual grass Bromus tectorum L. At five dryland sites in southeastern Utah, USA, resin bags were buried in experimental plots randomly assigned to combinations of two watering treatments (wet and dry), four chemical-amendment treatments (KCl, MgO, CaO, and no amendment), and four plant treatments (B. tectorum alone, the perennial bunchgrass Stipa hymenoides R. & S. alone, B. tectorum and S. hymenoides together, and no plants)…. When averaged across watering treatments, plots receiving KCl applications had lower resin-bag NO 3 − than plots receiving no chemical amendments during three of four measurement periods—probably due to NO 3 − displacement from resin bags by Cl− ions. During the January–April period, KCl application in wet plots (but not dry plots) decreased resin-bag NH 4 + and increased resin-bag NO 3 −. This interaction effect likely resulted from displacement of NH 4 + from resins by K+ ions, followed by nitrification and enhanced NO 3 − capture by resin bags. In plots not receiving KCl applications, resin-bag NH 4 + was higher in wet plots than in dry plots during the same period. During the January–April period, resin-bag measures for carbonate-related ions HPO 4 2−, Ca2+, and Mn2+ tended to be greater in the presence of B. tectorum than in the absence of B. tectorum. This trend was evident only in wet plots where B. tectorum densities were much higher than in dry plots. We attribute this pattern to the mobilization of carbonate-associated ions by root exudates of B. tectorum. These findings indicate the importance of considering potential indirect effects of soil amendments performed in conjunction with resource-limitation studies, and they suggest the need for further research concerning nutrient acquisition mechanisms of B. tectorum.

Development of artificially induced biological soil crusts in fields and their effects on top soil
Abstract
Aims
Biological soil crusts (BSCs) could improve severe environment ecological conditions by increasing soil moisture, soil nitrogen concentration, and so on. In order to control desertification and recover the destroyed soil fertility utilizing a new means using BSCs, the soil surface was artificially inoculated with Microcoleus vaginatus and Scytonema javanicum. Relationships between the development of the artificially induced biological soil crusts and the distribution and dynamic changes of nitrogen and phosphorus in the soil crusts have been analyzed.
Methods
Crusts of different ages were investigated by measuring soil physical and chemical factors, such as moisture, pH, total and available N content, and total and available P, which were correlated with the depths of the crusts.
Results
This study found that the types of color, shape, and species components of the algal crusts increased with crust development. Soil moisture, total N, available N, and available P increased gradually with crust growth. Soil with crusts was wetter than the controlled naked sandy soil, and a significant correlation was observed between biomass and total nitrogen (r = 0.946, P = 0.015). Soil pH was lower than that of control. The scytonemin on the soil surface was exceptionally higher than the other pigments, and all the pigments were mainly distributed at the soil surface level. Though the crusts were mainly distributed on soil surface, the available P was mainly stored below the crust layer.
Conclusions
<b.Pearson correlation tests indicated that artificially inoculated biological crusts could improve soil fertility and micro-environment of the top soil: The development of artificially induced BSCs was very well, and this was favorable to inducing the following crust succession.

But I did like the scary projected drop in your cited graph. Too bad it doesn’t seem to have any relationship to their own data or reality.
And their graph clearly shows increased yield per hectare with fewer hectares harvested. So if there really is a problem, just put some of those hectares that are no longer in production back into production. Combined with increased yield per hectare, problem solved.

Repeating something again:
Consider dairy in India. Let’s postulate that each Indian averages 8 oz of milk per day, or 62 million gallons of milk for the country. Someone has to grow the crops that feed the cows that produce the milk. Now lets add refrigeration to the country so that milk can be kept for weeks instead of hours between milking and drinking. Are more or fewer gallons poured out for going sour? Do we need more or less grain?
First world countries (with developed infrastructure and cheap reliable energy) are able to consume more calories even when fewer calories are produced. Any decline in produced grain absolutely must take this into account. In which countries do you think it is most likely for a large pile of corn to rot and be tossed? Probably not the one where there is controlled drying and humidity sensors in the storage silo. As these practices are adopted in other countries then we should expect grain production to fall (although an increase in protein consumption could hold the average stable).

“I think you misread the graph — it displays no projections.”
I know you need to go back to your original comment. The graph YOUR link goes directly too clearly shows projections past 2021.
Nice try and thanks for playing.

Ha. Lack of land is part of the problem, due to sprawl, population growth, water supply and climate change. There is little land going fallow, just waiting to be put back into production.

Really? You mean the half billion extra acres of trees in North America since the 18th century are just everyone’s imagination?
You mean that forest that was a farm just down the road from me, never produced?
Or do you mean it destroys your meme, and you have no facts to back up such a ridiculous assertion?

JP may hallucinate a dropping US/world population, but the projections are for the US to go well over 400 million by 2050. I and my children soooo look forward to California doubling again and again as it has done in my lifetime, from under 10 million to 38 million.

Raymond,
The projections do not measure to current population trends. The last 2 years have seen the lowest birthrates in US history. The 2010 Census had the slowest rate of population growth in the US since 1932. The US’s population is growing; but it’s only growing due to long life spans. According to Census Data in 2000 and 2010, only Hispanic immigration allowed our populations to rise. And the Hispanic TFR (Total Fertility Rate) in the US dropped from 3.36 in 2005 to under 2.2 in 2011. The TFR of Mexico has dropped from 6.0 in 1970 to 2.38 in 2012. The Median Age in the US is currently 37.5 years as compared to 24 in 1972. In other words, not only is the US significantly older, but even its immigrant population is failing to reproduce at replacement levels. The US population will only continue to grow because people are dieing off slower than newborns are entering the world. Once the Baby Boomers leave this world. the US population will drop significantly unless it is replenished with foreigners. That is not likely to happen.
As I stated earlier, Russia, Japan, almost all of Europe, and China are even in a worse position. Russia and Japan are already losing population. Germany is about to, as is Italy, Greece, Spain, Ireland and much of Eastern Europe. North Africa’s birthrate as now mostly below replacement levels of 2.1 births (down from an average of 5.5 births/female 40 years ago). Even India is headed for demographic problems. Most of South America has birth rates below replacement levels. Only portions of Africa and East Asia have positive birth rates.
Not sure where all this growth is going to happen. The UN’s own demographic data does not support its positive projections. If current trends continue. The world’s population will peak sometime between 2035-2040 before rapidly declining after 2045-2050.
