AbstractThis paper focuses on the positioning of animals other than human in the texts and practices of two versions of small-scale food "self-sufficiency" in Britain. The paper discusses the writings of Cobbett (1822/1926, 1830/1985) and Seymour (1960s/1970s) on self-sufficiency, suggesting that livestock animals are central, in a number of ways, to the constitution of these modes of self-sufficiency. First, animals are situated in both the texts and in the practicing of self-sufficiency regarded as essential parts of the economies and ecologies of small-scale food production. Second, animals' parts in these authors' criticisms of wider social, economic and political conditions supplement their role in small-scale domestic food supply. Animals become associated with a morality of human behavior and lifestyle and are part of the broader social critiques that the writing and practicing of these modes of self-sufficiency imply. These historically and geographically specific versions of self-sufficiency are valuable in defining and enacting possible alternative modes of human-animal relation in the context of food production.

Liberia's 14 year civil war destroyed domestic agricultural production, veterinary and agricultural education, extension services and domestic food security. These losses severely limited domestic food production, and basic hygiene and sanitation: potable water, abattoirs, cold chain and food storage were greatly diminished. The average Liberian life expectancy fell from 45.8 in 1990 to 41.8 years presently. The population birth and death rate are two of the highest globally with a resulting population growth rate, of 2.7% per annum; this growth rate requires an immediate and concerted focus on domestic food production to alleviate nutritional inadequacy and hunger, trade imbalances and loss of foreign exchange credits. Food supply nationally is presumed adequate because of importation, though domestic production is inadequate. Unequal distribution precludes food security for all Liberians. Value chain augmentation, enhancing food availability across all sectors of Liberian society and ensuring distribution of a safe food supply needs critical development. Infant mortality remains one of the highest in the world (approximately 160/1000 births), much of which is attributed to food insecurity, food contamination and lack of uniformly available potable water. Recreation of Liberia's public health and food security requires redevelopment of disease monitoring and laboratory diagnostic capability to re-establish safe food production and handling practices across all sectors. This will allow determination of endemic disease burden for the principal livestock species: poultry, sheep, goats, cattle and swine. Creation of a national disease surveillance/monitoring system allows for targeted disease intervention, ensuring vaccination for correct serotypes and most critically prevalent diseases. Creation of community level training and support will target intervention of local diseases, but also allow for national prioritization of diseases. Targeting which are most prevalent or most likely to cause production limiting effects will require periodic surveillance, targeted vaccination, and chemotherapeutic intervention and evaluation of therapeutic success.

In the current study, a domestic food waste containing more than 50% of carbohydrates was assessed as feedstock to produce second-generation bioethanol. Aiming to the maximum exploitation of the carbohydrate fraction of the waste, its hydrolysis via cellulolytic and amylolytic enzymatic blends was investigated and the saccharification efficiency was assessed in each case. Fermentation experiments were performed using the non-conventional yeast Pichia anomala (Wickerhamomyces anomalus) under both separate hydrolysis and fermentation (SHF) and simultaneous saccharification and fermentation (SSF) modes to evaluate the conversion efficiencies and ethanol yields for different enzymatic loadings. It was shown that the fermentation efficiency of the yeast was not affected by the fermentation mode and was high for all handlings, reaching 83%, whereas the enzymatic blend containing the highest amount of both cellulolytic and amylolytic enzymes led to almost complete liquefaction of the waste, resulting also in ethanol yields reaching 141.06 ± 6.81 g ethanol/kg waste (0.40 ± 0.03 g ethanol/g consumed carbohydrates). In the sequel, a scale-up fermentation experiment was performed with the highest loading of enzymes in SHF mode, from which the maximum specific growth rate, μmax, and the biomass yield, Yx/s, of the yeast from the hydrolyzed waste were estimated. The ethanol yields that were achieved were similar to those of the respective small scale experiments reaching 138.67 ± 5.69 g ethanol/kg waste (0.40 ± 0.01 g ethanol/g consumed carbohydrates).
