DEPROLETARIANIZING AGRICULTURE - RECOVERING AGRICULTURE FROM AGRIBUSINESS AND THE NEED FOR A COMMONS-BASED, OPEN SOURCE AGRICULTURE

N° ISBN - 978-2-7380-1284-5International audienceThis article deals with the biotechnology revolution in agriculture and analyzes it in terms of Bernard Stiegler's theory of techno-evolution and his thesis that technologies have an intrinsically pharmacological nature, meaning that they can be both supportive and destructive for sociotechnical practices based on them. Technological innovations always first disrupt existing sociotechnical practices, but are subsequently always appropriated by the social system to be turned into a new technical system upon which new sociotechnical practices are based. As constituted and conditioned by a technical system, human cultures are necessarily systems of care. Humans take care of themselves and the world through technologies. Agriculture is a very old system of care, stable for more than 10,000 years, but at the moment it is experiencing a profound rupture thanks to the invention of genetic engineering technologies, that promise to revolutionize it. However, their current deployment under capitalist conditions everywhere leads to processes of proletarianization, due to the fact that they enable the expropriation of farmers of the means of production, depriving them of the possibility of appropriating these new technologies and frustrating the invention of a new agricultural system of care. This has lead to a widespread rejection of the new technologies, which is a grave error though, as these technologies can become the basis of a new system of care. But only under the condition that they are wrought from corporate control and redeployed instead to initiate a process of deproletarianization. It is argued that current initiatives in open source and commons-based biotech are probably the most promising harbingers of such a process of deproletarianization

Sloterdijk: You Must Change Your Life. On Anthropotechnics; In the World Interior of Capital. For a Philosophical Theory of Globalization; Globes: Spheres II: Macrospherology

Although the German philosopher Peter Sloterdijk (1947) is certainly still not a well-known, let alone “settled” author within the Anglophone philosophical community that leans toward what is still frequently called “continental philosophy,” unlike similarly important figures such as Jean-Luc Nancy, Bruno Latour, Alain Badiou, Giorgio Agamben, Niklas Luhmann and Axel Honneth, his star is nevertheless slowly rising and many of his books have been translated in English in recent years. One of the reasons for this delayed reception in Anglophone academia might be Sloterdijk’s highly idiosyncratic approach to philosophy, his even more idiosyncratic, lavishly exuberant, intensely literary and (in my humble opinion) hardly translatable prose, as well as the enormous variety of themes his formidable versatile intellect engages itself with, which makes him a thinker who is very difficult to pinpoint or categorize. And although his work nevertheless touches to a large extent upon the same themes that many other “continental” thinkers address—from postmodernity and posthumanism to biopolitics and globalization—the way he frames those themes is so utterly original and so thoroughly different from the usual theoretical formats and frameworks that this work is not so easy to connect with. And last but not least, it appears to be strangely immune to academic appropriation/annexation

Sediment and nutrient retention capacity of natural riverine wetlands in Southwest Ethiopia

Although wetlands in temperate regions have been studied for their pollutant remediation potential, the sediment and nutrient retention capacity of natural wetlands in tropical environments remains understudied. In this study, a mass balance approach was used to estimate the amount of sediment and nutrients retained at 40 different study sites located in four natural riverine wetlands in Southwest Ethiopia. Awetu and Boye wetlands retained a substantial amount of total suspended solids (TSS) and nutrients whereas Kofe and Kito wetlands had a net release. Overall, the amount of TSS retained by the four wetlands was estimated to be 6266.5 kg/ha/day. On the other hand, the net retention of Total Organic Nitrogen (TON) and Total Phosphorous (TP) was estimated to be 37.6 kg/ha/day and 40.9 kg/ha/day, respectively. A stepwise multiple regression analysis revealed that anthropogenic activities such as farming, grazing, waste dumping and clay mining were the main variables that negatively affected the retention of TSS and nutrients. Farming alone explained 58% of the variation in TSS retention and cattle grazing explained 25% of the variation in TON retention. Therefore, watershed management interventions considering the mitigation of anthropogenic activities could be considered to reduce sediment and nutrient input and release

ecomodernism and the libidinal economy: Towards a Critical Conception of Technology in the Bio‑Based Economy

In this paper, we carry out a critical analysis of the concept of technology in the current design of the bio-based economy (BBE). Looking at the current status of the BBE, we observe a dominant focus on technological innovation as the principal solution to climatic instability. We take a critical stance towards this “ecomodernist” worldview, addressing its fundamental assumptions, and ofer an underarticulated explanation as to why a successful transition toward a sustainable BBE—i.e. one that fully operates within the Earth’s carrying capacity—has not yet been reached. Bernard Stiegler has developed a philosophical perspective on the concept of economy, broadening it to include the human condition through the notion of desire. This theory can help to obtain a more profound understanding of why ecomodernist strategies are dominant today. Stiegler’s theory of the libidinal economy ofers an analysis of controlled and exploited human desire as a primary driver behind modern techno-economic structures. Our hypothesis is that a critique of contemporary technofxism as a critique of libidinal economy is a necessary step to take in the discussion around the BBE as a concept, if the BBE is ever to bring about a system that can truly operate within the Earth’s carrying capacity

In silico identification and experimental validation of PmrAB targets in Salmonella typhimurium by regulatory motif detection

BACKGROUND: The PmrAB (BasSR) two-component regulatory system is required for Salmonella typhimurium virulence. PmrAB-controlled modifications of the lipopolysaccharide (LPS) layer confer resistance to cationic antibiotic polypeptides, which may allow bacteria to survive within macrophages. The PmrAB system also confers resistance to Fe(3+)-mediated killing. New targets of the system have recently been discovered that seem not to have a role in the well-described functions of PmrAB, suggesting that the PmrAB-dependent regulon might contain additional, unidentified targets. RESULTS: We performed an in silico analysis of possible targets of the PmrAB system. Using a motif model of the PmrA binding site in DNA, genome-wide screening was carried out to detect PmrAB target genes. To increase confidence in the predictions, all putative targets were subjected to a cross-species comparison (phylogenetic footprinting) using a Gibbs sampling-based motif-detection procedure. As well as the known targets, we detected additional targets with unknown functions. Four of these were experimentally validated (yibD, aroQ, mig-13 and sseJ). Site-directed mutagenesis of the PmrA-binding site (PmrA box) in yibD revealed specific sequence requirements. CONCLUSIONS: We demonstrated the efficiency of our procedure by recovering most of the known PmrAB-dependent targets and by identifying unknown targets that we were able to validate experimentally. We also pinpointed directions for further research that could help elucidate the S. typhimurium virulence pathway

Inferring transcriptional modules from ChIP-chip, motif and microarray data

'ReMoDiscovery' is an intuitive algorithm to correlate regulatory programs with regulators and corresponding motifs to a set of co-expressed genes. It exploits in a concurrent way three independent data sources: ChIP-chip data, motif information and gene expression profiles. When compared to published module discovery algorithms, ReMoDiscovery is fast and easily tunable. We evaluated our method on yeast data, where it was shown to generate biologically meaningful findings and allowed the prediction of potential novel roles of transcriptional regulators
