Bio-Umsatz übertrifft Sieben-Milliarden-Marke

Bio-Umsatz übertrifft Sieben-Milliarden-Marke | Agrarforschung | Scoop.it
Nürnberg - Der Umsatz mit Bio-Lebensmitteln in Deutschland hat 2012 die Marke von sieben Milliarden Euro durchbrochen.
AckerbauHalle's insight:

Bei aller medialen Begeisterung für die starke Ausdehung des Biobereiches sollte nicht ganz vergessen werden, welche Sektoren wachsen und welche nicht. Dabei wird beklagt, dass in Deutschland die Flächenentwicklung der begrenzende Faktor ist (Argumente: Hohe weltmarktpreise und Förderung der Bioenergie). Daraus leitet sich dann die Forderung nach mehr Fördeurng ab,

 

Erhebliches Wachstum zeigt der Bereich Obst- und Gemüse. DIes ist aber im wesentlichen durch zwei Faktoren begrenzt, die mit den o.g. Argumenten eher wenig zu tun haben. Klimatische Bedingungen und Arbeitskosten. Bei den Klima- und Bodenbedingungen in der Bundesrepublik - im großen Durchschnitt - sind die Vorteile im Anbau von Getreide, Raps, Zuckerrüben und eben nicht bei Gemüse. Und ob sich die Arbeitskosten ändern werden, möchte ich eher bezweifeln.

Glyphosate vulnerability explains changes in root-symbionts propagules viability in pampean grasslands

Abstract

Research into the impact of agricultural practices on plant symbionts is essential for understanding the factors that modulate plant community productivity and diversity. Although glyphosate is used worldwide as an herbicide, its effects on root symbionts under natural conditions have not been sufficiently studied. We performed a field experiment to evaluate the influence of glyphosate, used for promoting winter forage production, on the viability of arbuscular mycorrhizal fungi (AMF) and rhizobium propagules and other ecosystem traits in native grasslands. The number of viable propagules was strongly reduced with a single application at the recommended dose. Spore viability reduction was dependent on AMF species. Furthermore, changes in plant community composition and soil salinity were detected, which may eventually influence these symbionts in the future. Considering the low nutrient availability and high root-symbiont dependency of several species with forage value, repeated applications might lead to a loss in the grassland diversity and productivity, decreasing livestock production. Application of sublethal doses of this herbicide could avoid these damages, although success in increasing winter forage production would be less. Our results are relevant for understanding the effects of glyphosate on non-target species and designing sustainable land management systems.

Beyond GMOs: A new era of biotechnology | Biotech Traits content from Farm Industry News

Beyond GMOs: A new era of biotechnology | Biotech Traits content from Farm Industry News | Agrarforschung | Scoop.it
Executives from leading crop biologicals companies discuss how naturally occurring plant microbes are ushering in a whole new era of biotechnology that will give crops their next big boost in yields.

 

Twenty years ago the idea of 90-plus percent of the U.S. soybean and corn crops containing biotech content was just a pipe dream of a few technologists, yet today the industry has progressed that far. Based on what researchers are learning about plant and animal genomics, work in RNA interference and other key technologies, biotech today is clearly only at the beginning of a whole range of breakthroughs.

Climate variation explains a third of global crop yield variability

Climate variation explains a third of global crop yield variability | Agrarforschung | Scoop.it

"While some areas show no significant influence of climate variability, in substantial areas of the global breadbaskets, >60% of the yield variability can be explained by climate variability. Globally, climate variability accounts for roughly a third (~32–39%) of the observed yield variability."
Nice paper to remind students of the need for genetic diversity even within major crops like rice, wheat, maize and soybean, as they are grown in regions with tremendously varying conditions and stresses.

Organic and Conventional Milk – Comparing Apples to Apples? - Elsevier (2015)

Organic and Conventional Milk – Comparing Apples to Apples? - Elsevier (2015) | Agrarforschung | Scoop.it

Consumers perceive that organic cow milk differs from conventionally produced milk and that these differences justify the premium price for organic milk... researchers in New Zealand found that the differences between organic and conventional milk are not so straightforward.

Reviewing almost 200 publications, researchers concluded that previously conducted controlled studies... have so far been largely ambiguous... "When comparing organic and conventional milk composition... previous studies have generally compared organic dairying with milk produced from grass-fed cows to conventional dairying with milk produced from concentrate-fed cows. The differences in milk composition observed are actually due to the different diets of the cows (i.e. pasture versus concentrate feeding) rather than organic versus conventional farming systems"... 

 

The vast majority of differences reported between organic and conventional milk come from what cows are fed and their breed, and is not anything unique to being organic or conventional in itself." Therefore in terms of nutrients in milk, there is nothing distinct about organic milk that makes it unique from conventionally produced milk once the different factors that influence milk production are compared or adjusted for. If animal genetics, health, breed, diet, management, or environment differs, then so will the composition of the milk produced.

Who benefits from the rapidly increasing voluntary sustainability standards? - Minten &al (2015) - IFPRI

Who benefits from the rapidly increasing voluntary sustainability standards? - Minten &al (2015) - IFPRI | Agrarforschung | Scoop.it

Voluntary Sustainability Standards (VSS) are rapidly increasing in global value chains. While consumers, mostly in developed countries, are willing to pay significant premiums for such standards, it is not well understood how effectively these incentives are transmitted to producing countries.

 

We study VSS in Ethiopia’s coffee sector... We find that transmission of the export quality premiums to coffee pro-ducers is limited, with only one-third of this premium being passed on. Moreover, as quality premiums are small and average production levels in these settings are low, these premiums... have little effect on the welfare of the average coffee farmer.

Alexander J. Stein's curator insight, January 24, 11:31 AM

While IMHO organic standards should not have been included in these VSS as they do not focus on sustainability criteria but rather on an ideologically motivated avoidance of certain inputs, the question remains why poor smallholders in developing countries join such schemes? Given the notoriously lower average yields in organic farming, this shortfall has to be made up by higher profit margins -- which farmers in rich countries seem to be able to realise, but which apparently do not reach poor smallhoders (but are siphoned off by the organic industry).

FCRN | Farming overtakes deforestation and land use as a driver of climate change

Abstract

We refine the information available through the IPCC AR5 with regards to recent trends in global GHG emissions from agriculture, forestry and other land uses (AFOLU), including global emissions updates to 2012. By using all three available AFOLU datasets employed for analysis in the IPCC AR5, rather than just one as done in the IPCC AR5 WGIII Summary for Policy Makers, our analyses point to a down-revision of global AFOLU shares of total anthropogenic emissions, while providing important additional information on sub-sectoral trends. Our findings confirm that the share of AFOLU emissions to the anthropogenic total declined over time. They indicate a decadal average of 28.7±1.5% in the 1990s, 23.6±2.1% in the 2000s, and an annual value of 21.2±1.5% in 2010. The IPCC AR5 had indicated a 24% share in 2010. In contrast to previous decades, when emissions from land use (land use, land use change and forestry, including deforestation) were significantly larger than those from agriculture (crop and livestock production), in 2010 agriculture was the larger component, contributing 11.2±0.4% of total GHG emissions, compared to 10.0±1.2% of the land use sector. Deforestation was responsible for only 8% of total anthropogenic emissions in 2010, compared to 12% in the 1990s. Since 2010, the last year assessed by the IPCC AR5, new FAO estimates indicate that land use emissions have remained stable, at about 4.8 Gt CO2eq yr-1 in 2012. Emissions minus removals have also remained stable, at 3.2 Gt CO2eq yr-1 in 2012. By contrast, agriculture emissions have continued to grow, at roughly 1% annually, and remained larger than the land use sector, reaching 5.4 Gt CO2eq yr-1 in 2012. These results are useful to further inform the current climate policy debate on land use, suggesting that as many efforts and resources should be directed to agriculture mitigation in the coming years as they have been devoted to REDD+ in the past decade.

Degradation rate of soil function varies with trajectory of agricultural intensification

Degradation rate of soil function varies with trajectory of agricultural intensification | Agrarforschung | Scoop.it
Abstract

Efforts to maintain or increase food production in developed agriculture would be compromised if current high-intensity production was degrading supporting ecosystem services, such as the ability of soil to function. The link between cropping intensity, defined by pesticide and fertiliser applications, and soil biophysical status was examined at 70 sites in a high-yielding region of the UK, in which cropping sequences covering a wide range of intensity had diverged from a common low-intensity origin in the 1970s. Two sequences of still low or moderate intensity based on spring cereals or a low frequency of winter cereals formed comparators for three high intensity sequences based on winter wheat and potato which together were associated with adverse effects of −30% on soil carbon content in the upper soil layer (P < 0.001), −11% on soil water holding capacity (P < 0.01) and +15% on soil bulk density (P < 0.001). Negative effects were also found in some high intensity sequences on soil macroporosity and penetrometer resistance. Even in this high-yielding region, therefore, current forms of intensification are associated with adverse trends in soil condition that may be detrimental to future production. The effects of these trends in soil condition on agricultural output now need to be quantified, and the economic burden accounted for, if fields reduce their capacity to yield or need reparation to keep them productive.

Interessante Arbeit zu den Grenzen der Intensivierung. Es ist nicht alles in Ordnung, auch wenn dies auf den ersten Blick so scheinen mag.

Warum die Bodenpreise explodieren

Warum die Bodenpreise explodieren | Agrarforschung | Scoop.it
Berlin - Die Preisexplosion bei deutschen Ackerflächen hat viele Ursachen; in erster Linie wird der Markt aber von den landwirtschaftlichen Teilnehmern selbst getrieben.

 

Dieses Resümee ist diese Woche in Berlin beim 12. Bodenforum der Fachzeitschrift „agrarmanager“ gezogen worden, auf dem die Frage nach den bestimmenden Faktoren für die steile Entwicklung der Bodenpreise in den letzten Jahre gestellt wurde. Den Vorwurf einer marktbeherrschenden Rolle der Bodenverwertungs- und -verwaltungsgesellschaft (BVVG) auf dem ostdeutschen Bodenmarkt wies deren Geschäftsführer Stefan Schulz dabei mit Nachdruck zurück. Er betonte den gesetzlichen Privatisierungsauftrag der BVVG und den vergleichsweise geringen Anteil, den sie inzwischen bei freien Transaktionen von Flächen einnehme.

Auch ein gravierender Einfluss außerlandwirtschaftlicher Investoren kann nach einer Untersuchung von Prof. Silke Hüttel von der Universität Rostock zumindest für Sachsen-Anhalt ausgeschlossen werden. Nach Einschätzung des Direktors des Leibniz-Instituts für Agrarentwicklung in Transformationsökonomien (IAMO), Prof. Alfons Balmann, folgen die Preise am landwirtschaftlichen Bodenmarkt auch heute meist den ökonomischen Rahmenbedingungen. Er sieht allenfalls partiell Marktversagen, das politisch und strukturell gelöst werden müsse.

Canola rotation frequency impacts canola yield and associated pest species - Canadian Journal of Plant Science

Canola rotation frequency impacts canola yield and associated pest species - Canadian Journal of Plant Science | Agrarforschung | Scoop.it

Harker, K. N., O’Donovan, J. T., Turkington, T. K., Blackshaw, R. E., Lupwayi, N. Z., Smith, E. G., Johnson, E. N., Gan, Y., Kutcher, H. R., Dosdall, L. M. and Peng, G. 2015. Canola rotation frequency impacts canola yield and associated pest species. Can. J. Plant Sci. 95: 9–20. Canola (Brassica napus L.) production has been steadily increasing in western Canada. Here we determine the effect of canola rotation frequency on canola seed yield, quality and associated pest species. From 2008 to 2013, direct-seeded experiments involving continuous canola and all rotation phases of wheat (Triticum aestivum L.) and canola or field pea (Pisum sativum L.), barley (Hordeum vulgare L.) and canola were conducted at five western Canada locations. Fertilizers, herbicides, and insecticides were applied as required for optimal production of all crops. Canola rotation frequency did not influence canola oil or protein concentration or the level of major (composition>1%) seed oil fatty acids. High canola yields were associated with sites that experienced cooler temperatures with adequate and relatively uniform precipitation events. For each annual increase in the number of crops between canola, canola yield increased from 0.20 to 0.36 Mg ha−1. Although total weed density was not strongly associated with canola yield, decreased blackleg disease and root maggot damage were associated with greater canola yields as rotational diversity increased. Long-term sustainable canola production will increase with cropping system diversity.

FAO - News Article: Genetic diversity a hidden tool in coping with climate change

FAO - News Article: Genetic diversity a hidden tool in coping with climate change | Agrarforschung | Scoop.it

Genetic resources have a critical role to play in feeding the world — especially as climate change advances faster than expected — and much more needs to be done to study, preserve and utilize the biological diversity that underpins world food production, according to a new book released by FAO today.

"Time is not on our side" warns the book, Coping with climate change: the roles of genetic resources for food and agriculture."In the coming decades, millions of people whose livelihoods and food security depend on farming, aquaculture, fishing, forestry and livestock keeping are likely to face unprecedented climatic conditions."
