Innovative farming to combat climate change and soaring food prices

With food and crops prices soaring causing world-wide protest, the biofuel industry has come under heavy fire. In particular, biodiesel and ethanol production from corn, wheat, soy beans and other is questioned, but also biofuel production from other sources ; considering that the land could be used for food crops.
Biogas, should of course not course not be questioned in this way, as its relation to food prices is still very distant, and it is by far the most climate friendly biofuel.
The demand for crops is fueled by laws demanding a certain share of renewable energy (such as the
proposed EU-wide target of 10 percent by 2020) or subsidy programs (such as ethanol subsidies).

Other factors are even more important for crops prices, such as increased meat and bread consumption in China and India. Further on, some claim that the situation is worsened beceause of market inefficiency as a result of faulty goverment policies such as trade barriers and agricultural subsidies.

There are few reasons to believe that the situation is going to improve in a near future. Although it would be possible to improve efficiency, farming methods and logistics in some parts of the world, growing global demands for a higher living standard (including more meat) and for biofuels will keep increasing the prices.
In the medium term however, there are several interesting technologies that may not only increase productivity, but also decrease the need of farm land and replace some agricultural products entirely. They may seem rather un-orthodox, and perhaps even appalling to some. Still they may contribute to reduce the crops and food prices. How about:

In vitro meat
The livestock meat industry is very inefficient from an energy and nutritional point of view: 75% to 95% of what is used to feed the animal is lost through metabolism or transformed into inedible structures. Meat production needs up to ten times more energy per edible ton compared to grain production. In vitro meatis meat grown in laboratories, with ambitions to scale up the production to industrial scale in a near future. Basically, the meat is grown using stem cells or satellite cells, focusing on producing muscle fibers and fats. Hopefully, this could mean cheap meat with less animal suffering, less areal needed for grain production, less energy use and less methane emissions from livestock herds.


Chemical-free seed treatment
Although in vitro meat may raise some eye brows, most people would probably find the endeavors of Swedish-Dutch company Seedgard praiseworthy.
Crop diseases is a serious problem in several parts of the world, with recent outbursts of for instance black stem rust almost creating a disastrous famine. Traditionally, the seeds for sowing corn have been treated in chemical-intensive methods, to kill fungi and disease-generating organisms.
In the developing countries, not even the dirty methods are available to most farmers in the developing countries. Seedgard has developed a method for treating the seeds using hot air instead of chemicals, being no less efficient than traditional methods, and in some cases even more efficient.


Genetic engineering for better biofuel crops
From an environmental point of view, there are several reasons to be suspicious about genetically modified crops, which makes the use of modified crops for improved biofuel production a ”green dilemma”. Still, this branch of biotechnology could be an important part of the effort to reduce world hunger. During the last few years, research has been increasingly aimed at improving seeds and crops for biofuel production, in particular ethanol and biodiesel.
There are countless efforts in this field, with the variation of the type of research being great. Among the modifications are corn varieties that contain enzymes that otherwise would be needed to add later in the ethanol production, corn with a higher fermentable starch content (increasing the ethanol production with 2%-5%) to designing new biofuels from scratch. All of these efforts could be melted down to one desired result: more litres per acre.


Farm sky scrapers
If farms could be vertical rather than horizontal, less land would be needed for agriculture. This is something to have in mind when reading about projects as SkyFarm, a Toronto real estate project where food will produced in a 58-floor building. There are other projects under planning as well. Among the benefits growing vegetables and crops in an artificial environment in skyscraper like buildings: producing the food in urban areas, closer to the consumers reduces transport costs (and thereby emissions), protect the crops from pollution and unpredictable weather and against diseases.


Time will tell, which of these concepts will make a real difference in the quest for cheaper food and more biofuel. From an investor point of view, it is interesting to follow a few related companies closely, in particular gene-tech and seed companies such as Ceres, Syngenta and Targeted Growth.

Ethanol worse than oil?

Grist, quoting a recent study in Science, reports that the production and use of ethanol may make a larger contribution to global warming than the same amount of oil would have. These results are reached by considering the forests and grasslands being razed for biofuel crops plantations.
This is no surprise for ethanol skeptics. But it does underline the importance of detailed assessments, from source to end use, when comparing the environmental and climate impact of different type of fuels.

What will be the primary source of energy for our vehicles in 20 years? Electricity? Hydrogren? DME? One can only make a qualified guess. It is clear however that it is something that will depend upon political decisions as much as market logics.

And ethanol makes food prices soar as well.

Risk för cleantechbubbla? Knappast. Däremot för enskilda företagsbubblor

Dagens Miljö skriver idag om risken för en cleantechbubbla. Visst, på kort sikt kan enskilda företag och delsektorer att sjunka i värdering, till föjld av uppskruvna förväntningar. Detta kan tillfälligt drabba hela sektorn. Men cleantechsektorn som helhet har större potential, särskilt om man sprider sina ägg.
Jag har redan skrivit om detta här, och om att nästa "boom" kommer inom energieffektivisering.

"Boomen" vi sett är i stort sett logisk och marknadsmässig.
Självklart kommer enskilda företag av olika skäl inte klara sig i konkurrensen, och vissa företag är säkerligen övervärderade redan idag.
T.o.m. hela delsektorer kan komma att krascha. Marknaden kommer till exempel så småningom att straffa t.ex. etanolsektorn p.g.a. lågt energiutbyte för vissa former av etanol (majs&spannmål), och externa kostnader för andra typer (jatropha). En eventuell rekyl inom en delsektor kommer att drabba hela sektorn, dock tillfälligt.
Cleantechsektorn som helhet kommer på lång sikt snarare bara öka, eftersom fler blir varse om de externa kostnaderna i ett icke-hållbart samhälle. Förnyelsebar energi behövs inte bara p.g.a. klimatförändringar, utan också av säkerhetsskäl och för energioberoende. Även andra delar av cleantechsektorn kommer att gynnas i takt med att länder blir rikare och efterfrågar en renare miljö. Dessutom har investerare dotcom-bubblan i färskt minne och kommer att vara mkt mer kritiska i granskningen av förhållandet mellan nuvarande vinster & värde.
