Migration in West Africa: a savanna village perspective

The author describes the determinants and impact of temporary labor migration from northern Ghana, an area dependent on subsistence agriculture, to the south, where employment opportunities in mining, commercial agriculture, and the public sector are relatively abundant and higher-paying. The effects on social organization, agriculture, and population dynamics are discussed. (SUMMARY IN FRE)     

Language Diversity in West Africa: An Ecological Approach

Analysis of a linguistic atlas reveals an ecological gradient in the diversity of languages in West Africa. As one moves south from arid into lusher ecoclimatic zones, the average size of ethnolinguistic groups decreases. Various factors are considered which may have contributed to this distribution. I argue that the ethnolinguistic map is primarily a reflection of the systems of generalized exchange and mutual dependence into which people enter. It is hypothesized that such social networks function to reduce subsistence risk due to variations in the food supply. If this hypothesis is correct, the average size of ethnolinguistic groups should be inversely proportional to the degree of ecological variability they face. This prediction is tested and found to hold strongly for a large part of West Africa. There is also limited evidence of a correlation between linguistic diversity and topography. It is concluded that ecological risk has been a key historical force in West Africa and that the ethnolinguistic mosaic can be used as a valuable “fossil record” of people's adaptive social and economic strategies.     

Containers and mobility in West Africa

In West Africa, containment practices have long been localized in their production, moulded by environmental forces, and scaled to the human body. In the twentieth century, fossil fuels have changed how people keep and carry things. But newer technologies have tended to alter, rather than eliminate, older forms of storage.     

The early city in West Africa: towards an understanding

The dominating paradigm of urbanism in West Africa is steadily shifting from the city-centric to the dynamic consideration of the city's function within a wider settlement hierarchy. The authors appraise these theoretical positions and discuss the methodologies appropriate to each. Following the thematic framework developed in the theory and method sections, we then consider what research at the major early town sites has to date revealed about the chronology, course, and circumstances of urbanism in West Africa. Data available from the several sites considered is highly uneven. Analysis, even when quality data are available, has in some cases been hindered by a limiting theoretical approach. Although urban investigations in West Africa are only in their infancy, it is clear that cities are but one of several institutions indicating the early, indigenous emergence of hierarchically-ordered societies. With the recent demonstration that at least some West African towns represent indigenous processes of urbanization, the comparative study of factors contributing to urban growth and alternative urban paths becomes imperative.

Résumé Le paradigme dominant de l'urbanisme en Afrique de l'ouest change progressivement de l'aspect cité-centrique à la considération dynamique de la ville au sein d'une hiérarchie d'établissement plus vaste. Les auteurs évaluent ces positions théoriques et discutent des méthodologies appropriées à chacune. Suivant le cadre thématique élaboré dans les sections sur la théorie et la méthode, ils considèrent ensuite ce que la recherche dans les sites urbains primitifs principaux a révélé jusqu'à présent quant à la chronologie, le développement et les circonstances de l'urbanisme dans l'Afrique de l'ouest. Les données provenant des nombreux sites considérés sont très inégales. Même lorsque des données de qualité furent disponibles, l'analyse fut dans certains cas entravée par les limites imposées par l'approche théorique. Bien que les investigations urbaines en Afrique de l'ouest n'en sont qu'à leurs débuts, il est évident que les villes ne sont que l'une des nombreuses institutions signalant l'apparition indigène précoce de sociétés à ordre hiérarchique. Sachant maintenant qu'au moins certaines villes de l'Afrique de l'ouest représentent des processus indigènes d'urbanisation, il est maintenant impératif que soit effectuée l'étude comparative des facteurs contribuant à la croissance urbaine et aux diverses voies conduisant à l'urbanisation.

     

Transnational organized crime in West Africa: the additional challenge

Despite its vast natural and human resources and the undisputed progress made in the last decade towards the establishment of democratic culture and governing systems, West African countries continue to occupy the bottom ranks of the UN Human Development Index. Similarly, many of them score poorly in World Bank and Transparency International indexes that measure good governance. The international mass media have recently highlighted the role played by the West African region in the transatlantic cocaine trade, as well as in the flow of illegal migrants to Europe. Drugs and migrants are, however, just two of the numerous illicit activities that feed the growth of local and transnational criminal organizations, and the establishing of a culture of quick and easy money that is progressively eroding the foundations of any sustainable and well balanced socio‐economic development. The pervasive power of the corruption of criminal organizations, coupled with a general crisis by state actors in the administration of justice and enforcement of the rule of law, contribute towards the progressive diminishing of the credibility of the state as the institution entrusted with the prerogatives of guaranteeing security (of people and investments) and dispensing justice. In this context, the case of Guinea Bissau is probably the clearest example of what West African states may face in the near future if the issues of justice and security are not properly and promptly addressed. If primary responsibilities lie with West African governments and institutions, the international community as a whole should also review its approach to development policies by not only mainstreaming the issues of security and justice in their bilateral and multilateral agendas, but also by making it an essential cornerstone of policies and programmes aimed at supporting good governance and the establishment of states ruled by the law.     

Combating light weapons proliferation in West Africa

Light weapons proliferation is a serious problem in West Africa. A regional moratorium on imports of small arms and light weapons has not worked and UN arms embargoes on Sierra Leone, Liberia and Côte d'Ivoire have had limited impact. The Economic Community of West African States is currently drafting a new binding legal instrument aimed at controlling flows in West Africa but this will only succeed if the heads of state and government seriously adopt it. This needs to include greater compliance of UN sanctions, international reform of the End User Certificate system, mapping the spread of artisan production and an examination of ammunition imports to West Africa. Better control of ammunition imports in particular may assist the combat of light weapons proliferation as well as the comprehensive destruction of weapons from disarmament efforts. The illicit weapons trade in West Africa is increasingly transnational and it requires regional and international cooperation and support to combat it.     

The economic development of West Africa

Almost all documented landslides in Scotland belong to one of four categories: non‐rotational rock slope failures (major rockfalls, translational slides, topples or sags, often in some combination); rotational rock slope failures; debris flows; and translational slides in drift or regolith. Non‐rotational rock slope failures are particularly common on Highland metamorphic rocks, especially schists, and on igneous scarps in the Hebrides and Midland Valley; rotational rock slope failures almost invariably occur in weak sedimentary rocks overlain by resistant igneous rocks; and debris flows are most common on sandy drift or regolith. Former glacial activity has also been of importance in determining landslide distribution. The great majority of rock slope failures are ancient features, but debris flows and small translational slides in drift (both triggered mainly by intensive rainstorms) are much more frequent at present and cause much greater damage, particularly to communications.     

南非西海岸的春天 姹紫嫣红

<正>南半球的季节与我们北半球正好相反。8月底至9月,正是南非的初春。离开开普敦,沿着开普敦-纳米比亚景观大道一路向北,前往我们此行的重要目的地之一——南非西海岸国家公园。西海岸国家公园是一片面积很大的自然保护区,这里有着丰富的自然资源,包括植被、海滩、礁石、湿地等。每年的冬末春初,南非干旱的大地迎来勃勃生机,植物们趁短暂的雨季蓬勃绽放,成为南非著名的春季花海。
