The emergence of an ‘ethnic economy’? The spatial relationships of migrant workers in London's health and hospitality sectors

This paper examines how the globalized nature of London's service sector redefines spatial relationships for recent migrants working in the health and hospitality industries. Findings from the qualitative data demonstrate that recent temporary migrants to the UK employ broader strategies to secure employment than accounted for by current theories. The migrants in our case studies overwhelmingly utilized global and local recruitment and employment agencies, as well as sought employment in industries already established as ‘ethnic economies’. We suggest that this might be attributed to a lack of interaction with established co-ethnic immigrant communities; temporary migration trajectories; and living arrangements with co-migrants. We conclude by emphasizing the need to broaden our understanding of ethnic economies and social networks in light of these changing spatial relationships that have emerged through the globalization of the service sector in the UK.     

THE BARRED MINNOWS (TELEOSTEI: CYPRINIDAE) OF ZIMBABWE: IS THERE CAUSE FOR CONCERN?

Summary

Two species of barred minnow, Opsaridium zambezense and O. peringueyi, occur in Zimbabwe. The former is widely distributed in the Zambezi basin and some other rivers but is now absent from Lake Kariba and possibly some of its tributaries. The latter, which was only recently recognised as a distinct species and admitted to the Zimbabwean list, is much scarcer. It occurs in the Save and Limpopo catchments and there are only four specimens in the Natural History Museum of Zimbabwe collection. These specimens are all more than 40 years old and the lack of more recent ones suggest that O. peringueyi may be extinct, or close to extinction, in Zimbabwe. This situation may have come about through habitat alteration and drought, and emphasises the need for further monitoring of the current occurrence/distribution of fish species in the country.     

Alighting sites of female Tabanidae (Diptera) at Rekomitjie, Zimbabwe

Twenty-one species of Tabanidae from four genera were recorded. Where samples were large enough, the preferred alighting sites were determined for the tabanids, and differences in such sites were found for species in three genera. The lower legs of the bait ox were the preferred alighting site for 61.8% of the flies. In the season of peak fly numbers, the bait ox was under stress from the tabanids.     

Weekly variation in physical activity of the Oraon agricultural labourers of Jalpaiguri district,West Bengal

The energy expenditure due to habitual physical activity is known to depend on several factors, but possible effects of most of the determinants are not clearly known. The present study deals with weekly variation in energy expenditure of the Oraon agricultural labourers of Jalpaiguri district, West Bengal, India. The results show that, among males, there are significant differences between days of the week. But females do not show any such trend. The possible explanation of the results are the sociocultural practices of the studied population.     

Environmental NGOs,dispossession, and the state: The ideology and praxis of African nature and development

Zimbabwe provides a significant context to examine the interplay of the new development rhetoric, the actions of powerful conservation organizations, donor policies, a relatively strong and stable government, and the empowerment of local communities. This interplay exists in diverse rural areas where the Communal Areas Management Program for Indigenous Resources (CAMPFIRE) is in various stages of experimentation and implementation. CAMPFIRE has been described as a philosophy of sustainable rural development that enables rural communities to manage, and benefit directly form indigenous wildlife. It is the best known of African efforts to permit African communities to re- assert their management of selected natural resources. The program has the official support of the Zimbabwean government. Nonetheless, there are many potential areas of serious conflict. Three case studies are utilized to explore how the challenges of repossession of critical environmental resources by marginalized communities in the changing context of state and NGO relationships where international tourism is a revenue generator for both the private sector and government.     

The role of community-based wild resource management in Zimbabwe

Wildlife was in decline in Zimbabwe while the resource was being managed centrally by the State in terms of conventional protectionist legislation. The legislation was changed in 1960 and this led to cautious institutional reforms, whereby responsibility for wildlife was gradually devolved to landholders who were encouraged to use it profitably. This was achieved without the State abrogating its ultimate responsibility for the wellbeing of the resource.The CAMPFIRE programme was a response to the particular requirements of communally managed wild resources. Successful implementation required that appropriate institutions were in place. These allowed the peasants a meaningful say in the management of their wildlife and permitted them to use it profitably to generate a sufficient incentive to persuade them to conserve the resource on their land. As on large-scale commercial ranches, socio-economic factors proved more significant than ecological considerations in preserving wildlife on communally occupied land that is representative of much of Africa and the Third World.Former Director of National Parks and Wild Life Management, Zimbabwe.     

New migrant businesses and their workers: developing,but not transforming,the ethnic economy

ABSTRACT

Studies of businesses established by migrants to the UK traditionally stressed co-ethnic relationships as economic resources. More recent work identifies a new ethnic economy characterized by migrants’ common experiences, with ethnicity playing less of a role. The present study complements this newer perspective through investigation of the experiences of forty-nine business owners and sixty of their workers in the West Midlands. Economic relationships were central to the operation of migrant firms, and a minority of firms escaped from sectors traditionally dominated by migrant firms. Yet substantial continuity was also evident, including exclusion from the mainstream on ethnic lines and relations with workers characterized by informality. Migrant business is evolving but it retains many of its features; this pattern can be explained by combining the mixed embeddedness theory of the enterprise with labour process analysis.     

Adaptive strategies in the breakdown of shifting cultivation: The case of Mambwe,Lamha, and Lala of northern Zambia

Many researchers have commented on the remarkable ability of African shifting cultivators to adjust their agricultural methods to available resources. In northern Zambia, where the shifting cultivators depend on woodlands as an agricultural fallow crop, deforestation is prevalent under the increasing population pressure. Adaptations to the less vigorous forest cover have taken various forms, but all of them can be described as succession to a common system of shifting cultivation. In many respects, these can be regarded as part of a process of agricultural adaptive radiation as the affected populations were pushed into new environments as a result of warfare and/or population pressure.     

The filling phase of Mazvikadei Reservoir,Zimbabwe

Limnological measurements during the first year of filling of the newly formed Mazvikadei Reservoir in Zimbabwe showed variations in dissolved oxygen as well as soluble forms of phosphorus and nitrogen. The ratios of calcium to other major cations were: Ca:Mg = 0.38, Ca:Na = 0.50 and Ca:K = 2.0. The low Ca:Mg ratio may suppress development of mollusc populations, thus keeping the reservoir snail free. Conductivity was 160 μScm^-1. Daytime pH was 6.95–7.8. The water was dark-brown in colour, 90% of incident light was attenuated in the top 0.75 m in May, and in the top 3.5 m in August. Positive net photosynthesis was only recorded above a depth of 0.1 m, at 0.5 m and 1.0 m depths, it was negative. Zooplankton consisted of nine rotifer, four cladoceran, two cyclopoid and one calanoid species.     

The inshore fish yield potential of Lake Kariba, Zimbabwe

Four surplus yield models were used to estimate the yield potential of the Kariba inshore fishery. The classical methods gave maximum sustainable yield (MSY) values as high as 1333 t y-¹. These values are regarded as over-estimates in view of the present average annual catch of 619.4 t y-¹. The Schnute (1978) model gave an MSY of 719t y-¹ and a failure index close to 1 indicating that the data do not fit well into the model. Walter's (1986) graphical approach of fitting an approximate equilibrium yield curve to catch and effort predicts an MSY between 550 and 570t y-¹. It is suggested that the Kariba inshore fishery on the Zimbabwean side should be managed within this range, in Basins 4 and 5.

Résumé

Quatre modèles de rendement excédentaire ont été employés pour estimer le rendement potentiel de la pêcherie dans le lac Kariba. Les méthodes classiques donnaient un rendement maximal supportable (RMS) de 1333 ta-¹. On considere que ces valeurs sont surestimées au vu de la capture annuelle moyenne de 619 ta^-1. Le modèle de Schnute (1978) donnait un RMS de 719 ta^-1 et un risque d'erreur proche de 1, indiquant que les données ne s'intègrent pas bien dans le modèle. L'approche graphique de Walter (1986) qui tend à ajuster un niveau de rendement en équilibre approximatif entre I'effort et la prise prévoit un RMS compris entre 550 et 570 ta^-1. On suggère que la pêcherie dans le lac Kariba devrait être gérée dans cet ordre-là du côté zimbabwéken.
