Tribes, state, and technology adoption in arid land management, Syria:

Arid shrub-lands in Syria and elsewhere in West Asia and North Africa are widely thought degraded. Characteristic of these areas is a preponderance of unpalatable shrubs or a lack of overall ground cover with a rise in the associated risks of soil erosion. Migrating pastoralists have been the scapegoats for this condition of the range. State steppe interventions of the last forty years have reflected this with programs to supplant customary systems with structures and institutions promoting western grazing systems and technologies. Principal amongst the latter has been shrub technology, particularly Atriplex species, for use in land rehabilitation and as a fodder reserve. This paper deconstructs state steppe policy in Syria by examining the overlap and interface of government and customary legal systems as a factor in the history of shrub technology transfer in the Syrian steppe. It is argued that the link made between signs of degradation and perceived moribund customary systems is not at all causal. Indeed, customary systems are found to be adaptive and resilient, and a strong influence on steppe management and the fate of technology transfer initiatives. Furthermore, developments in rangeland ecology raise questions about claims for grazing-induced degradation and call for a reinterpretation of recent shifts in vegetation on the Syrian steppe. Given the ineffectiveness of past state interventions, and in view of renewed understanding of customary systems and rangeland ecology, decentralization and some devolution of formal management responsibility is likely to be a viable and an attractive option for policymakers.

Analysis of agribusiness value chains servicing small-holder dairy farming communities in Punjab, Pakistan: three case studies

The agriculture sector in Pakistan, as in most developing countries, is dominated by smallholder producers. Pakistan has the world’s third largest dairy industry, and milk is efficiently collected and distributed chiefly by informal value chains that market the raw product with minimal cool chain infrastructure. Formal processors have a small market share of 5%. Interview data from farmers, milk collectors and consumers from three rural-urban case study value chains were analysed to study opportunities and challenges faced by the dairy industry. Compositional analysis of milk samples (n=84) collected along these chains identified the fact that in Pakistan informal milk chains provide a cheaper source of calories for the final consumer than industrialised milk chains (USD 0.12 compared USD 0.15 per 100 calories). These three chains created an estimated 4,872 jobs from farm to market and provided access to interest-free credit for the farmers. The existing government price setting mechanism at the retail end and collusion by large processors to set farm gate prices provided significant limitations to the profitability of small-holder farms providing the product. The absence of quality and quantity standards, amid the exchange of huge numbers of small volumes of milk along these chains, are major impediments to industry growth

Dairying and whole-farm economics of crop-livestock farming systems - comparing arid and irrigated districts of Punjab, Pakistan

Dairying is an important component of Pakistan’s mixed crop-livestock farming systems. The national economy engages some 8.8 million small-scale producer households. The country produces more milk than any other except for the United States and India. Yet little is known about small-scale producer microeconomics to inform policy development for improving their welfare. In this paper we aim to identify the whole farm profitability of small agricultural households, with a specific focus on milk production. We compare two contrasting agro-ecological regions within Pakistan’s Punjab (irrigated Okara and rain-fed Bhakkar) using results for a single 2008-09 fiscal year of production for 212 farms. Net farm profits, taking long-run opportunity costs of labour and capital into account, showed only 10 per cent of these farms to be profitable in either district, though short-run profits, accounting for cash costs only, showed positive whole farm gross margins for 90 per cent and 80 per cent of farms in Okara and Bhakkar, respectively. The returns on assets (at 2.78 per cent and 0.53 per cent for the two districts) was lower than the national average return on savings (9 per cent). For dairy enterprises, total costs were higher than incomes; so many farms (70 per cent and 60 per cent, respectively) were assessed as making losses. Given the low opportunity costs of feeds (often crop residues) and of labour (6.2 per cent unemployment) and the high rate of inflation (11.8 per cent), returns on factors of production including labour and capital, may not be lower than international standards. There is a need, however, to raise the dairy industry’s overall productivity to make dairying viable; and to identify an optimal land and livestock combination that is profitable and commercially viable

Drought shocks and gearing impacts on the profitability of sheep farming

The resilience and profitability of livestock production in many countries can be impacted by shocks, such as drought and market shifts, especially under high debt levels. For farmers to remain profitable through such uncertainty, there is a need to understand and predict a farming business’s ability to withstand and recover from such shocks. This research demonstrates the use of biophysical modelling linked with copula and Monte Carlo simulation techniques to predict the risks faced by a typical wool and meat lamb enterprise in South-Eastern Australia, given the financial impacts of different debt levels on a farming business’s profitability and growth in net wealth. The study tested five starting gearing scenarios, i.e., debt to equity (D:E) ratios to define a farm’s financial risk profiles, given weather and price variations over time. Farms with higher gearing are increasingly worse off, highlighting the implications of debt accumulating over time due to drought shocks. In addition to business risk, financial risk should be included in the analyses and planning of farm production to identify optimal management strategies better. The methods described in this paper enable the extension of production simulation to include the farmer’s management information to determine financial risk profiles and guide decision making for improved business resilience

A rapid and sensitive screening method for the detection of anti-2-acetylaminofluorene immunoglobulins

A method is described in which anti-2-acetylaminofluorene immunoglobulins may be detected using a simple and sensitive screening procedure. The method is based on immunoglobulin binding of an 125I derivatized 2-aminofluorene radiotracer. Tracer binding is not isotype specific, and thus the method is useful for the detection of either IgG or IgA. Competitive binding experiments with the radiotracer were used to determine the specificity of immunoglobulin response by measurement of cross-reactivity with related ligands. This method allows quantitation of the immune response to the carcinogen in serum and other biological fluids (i.e., intestinal secretions).Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27330/1/0000354.pd
