A political ecology of socio-economic differentiation: debt,inputs and liberalization reforms in southwestern Burkina Faso

This paper builds on work from the agrarian change and political ecology literatures to analyze the process of agrarian change among smallholder cotton farmers in southwestern Burkina Faso. Specifically, we use a rural survey of 72 heads of household in three villages to examine whether and how (1) access to agricultural inputs, (2) debt and (3) liberalization reforms combine to produce rural socio-economic differentiation based on wealth. We find that wealthier farmers use more mineral fertilizer and manure inputs than their poorer counterparts. Wealthier farmers are also better able to remain debt-free as cotton prices drop and input prices rise. Moreover, they are able to take advantage of the neo-liberal restructuring of cotton cooperatives to change polices on debt repayment and input provisioning to their favor. This growing divide has large implications for rural food security, particularly as land becomes scarcer, fallows disappear and the need to intensify production grows. This research addresses two gaps in the agrarian change literature in relating how liberalization reforms and biophysical elements drive rural socio-economic differentiation. This work also shows that merging the concerns of political ecology with the agrarian change literature allows for a deeper examination of rural socio-economic differentiation.     

Soft budgets and elastic debt: farm liabilities in the agrarian political economy of post-Soviet Tajikistan

ABSTRACT

Since Tajikistan’s independence, market reforms and pressure from international donors have brought changes to the state’s role in the economy. The official narrative holds that the post-socialist state reduced its control over agriculture, but there are still various mechanisms through which it exerts control over farming. In this paper, I examine Tajikistan’s post-socialist agrarian change through the prism of farm debt. Farm debt used to be an accounting nuisance in Soviet agriculture as a result of so-called soft-budget constraints. In the political economy of post-socialist transformation, farm cotton debt has been transformed into indebted land. I classify this debt ‘elastic’ for its ambiguous nature. It ties farmers to land and makes farmers’ independence illusory. With an in-depth analysis based on original ethnographic insights, I aim to provide a theoretical contribution to the way in which debt is conceptualised and politicised in post-Soviet Tajikistan.

元代,中国、东南亚和印度之间存在着一个贩卖西洋布即印度棉布的贸易圈.明代东南亚一些国家把西洋布作为贡品带入中国.十六世纪开始,东来的西方殖民者不但垄断了原产印度西洋布的贸易,并使之成为香料贸易的补充,同时也带来了产自西欧的西洋布.西洋布一经传入中国,就成为人们喜爱的奢侈品.     

State science,risk and agricultural biotechnology: Bt cotton to Bt Brinjal in India

Agricultural biotechnology has been a project of India's developmental state since 1986, but implementation generated significant conflict. Sequential cases of two crops carrying the same transgene – Bt cotton and Bt brinjal (eggplant/aubergine) – facing the same authorization procedures produced different outcomes. The state science that approved Bt cotton was attacked as biased and dangerously inadequate by opponents, but the technology spread to virtually universal adoption by farmers. Bt aubergine was approved by the same Genetic Engineering Approval Committee (GEAC), but the decision was overruled, the GEAC downgraded and a moratorium imposed on the crop. Resultant conflicts engaged international networks, expanded the domestic arena in which science is contested and instigated restructuring of institutions for governance of genetic engineering. Divergent trajectories of the two crops corresponded to global patterns, but also reflected differences in agro-ecologies and state interests. In Bt cotton, state and cultivator interests dominated precautionary logics; in Bt eggplant, politics of risk dominated questions of agro-economics. The cases illustrate both the inherent vulnerability of science in politics and specific vulnerabilities of science embedded in particular institutions. Differences in institutional specificity of state science matter politically in explaining variation across countries in adoption and rejection of genetically engineered crops.     

Reviving the Kansai cotton industry: engineering expertise and knowledge sharing in the early Meiji period

This article analyses the acquisition and application of new cotton spinning technologies in Japan in the early Meiji period, and the ways in which this knowledge helped to mobilise existing resources of human and financial capital. It focusses on the early development of three pioneering firms, the Hirano, Amagasaki and Settsu companies, all of which after 1918 became part of Dainihon Spinning, one of the ‘Big Three’ textile firms of prewar Japan. By looking at the ways in which these companies diffused technical and other expertise, secured finance, and addressed the problems that had confounded earlier initiatives, it shows how technological knowhow from outside the Osaka region was a key factor that enabled the mobilisation of the capital and expertise of business and personal networks in Kansai, and in the process rebuilt the region's traditional predominance in cotton production, laying the foundations for the industry's global competitiveness.     

The utility of polyester and cotton as swabbing substrates for the removal of cellular material from surfaces

Various types of cotton and polyester fabrics were tested to ascertain the optimal physical and chemical characteristics of fabrics needed for the removal of cellular material from surfaces. DNA quantitation values obtained on dried saliva stains showed no difference between cotton and polyester across all constructions and solvent conditions. Fabrics used dry and with water yielded higher quantitation values than those used with isopropanol. Quantitation values were also higher for wovens and nonwovens than knits across all solvent conditions. Low thread count fabrics used with water yielded higher quantitation values, but no correlation between thread count and quantitation values was observed with dry fabrics. A low thread count woven fabric, however, outperformed other tested fabrics when swabbing object surfaces in a highly used room. Full DNA profiles from fingerprints on glass surfaces were obtained with low thread count woven and nonwoven fabrics but not with the knit fabric tested.     

The Extraction and Recovery Efficiency of Pure DNA for Different Types of Swabs

The extraction and recovery efficiency of swabs used to collect evidence at crime scenes is relatively low (typically <50%) for bacterial spores and body fluids. Cell‐free deoxyribonucleic acid (DNA) is an interesting alternative compared to whole cells as a source for forensic analysis, but extraction and recovery from swabs has not been tested before using pure DNA. In this study cotton, foam, nylon flocked, polyester and rayon swabs are investigated in order to collect pure DNA isolated from saliva samples. The morphology and absorption capacity of swabs is studied. Extraction and recovery efficiencies are determined and compared to the maximum theoretical efficiency. The results indicate that a substantial part of DNA is not extracted from the swab and some types of swab seem to bind effectively with DNA. The efficiency of the different types of swab never exceeds 50%. The nylon flocked 4N6FLOQSwab used for buccal sampling performs the best.     

The New Breed

正The debate on GM food continues,raising more concerns over food safety among the public On March 30, the Hainan Provincial Agricultural Department released a statement on its website, saying that nine corn and cotton samples out of 107 specimens planted in the southernmost Chinese province were identified as genetically modified (GM) last December and that they had been immediately destroyed The department also revealed that the samples came from il-
