The Apuseni Mountains, part of the Western Carpathians, are distinctive in cultural terms because of the highly dispersed settlement patterns that have developed on the high erosion surfaces where the Moti people cleared the forests to allow for an expansion of family farming in the eighteenth and nineteenth centuries. These small ‘crang’ settlements remain, but the population is declining in the face of limited employment opportunities and poor services. The question arises as to the most appropriate rural development strategy for the region, following the communist period which encouraged centralisation through the provision of housing and industry in key villages and new towns. The emphasis on private farming and the expansion of tourism could protect the inherited cultural landscape but money must be found to improve rural services. There is also a strong conservation movement which supports the establishment of a national park, but this could constrain development through controls on grazing and woodcutting. Hence the dialogue continues to find the best compromise and the concept of a ‘natural park’ is being discussed with such a reconciliation in mind. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

In Africa, the development of water resources for irrigation is seen as crucial for the recovery from current crises. This paper examines two issues generated by the geography of river systems which pose political as well as technical and economic questions. First is the problem of inter-state cooperation, where river systems cross political boundaries. Second is the domestic debate that arises from the differential access to water supply through the pattern of water rights. These issues are illustrated with material from Swaziland, a small landlocked state in southern Africa. Here, regional political tensions exacerbate the problems of long-term water development.  相似文献

Skills development for tourism has attracted only a limited scholarship in the developing world. In this paper the role of skills development in advancing South Africa's tourism-led development strategy is investigated. Skills development has a central role to play in ensuring the effective and sustainable transformation and development of the tourism industry in developing countries and, in the case of South Africa, in ensuring that poorer South Africans begin to benefit from this industry. It is argued that the current lack of an integrated and co-ordinated approach to tourism skills development seriously limits the potential of skills development to impact positively on tourism transformation and development in South Africa.

In Kenya the government is promoting diversification of crops to embrace high value crops and drought resistant crop varieties in efforts to reduce poverty in rural areas. Sugar beet is one of the crops considered as an option in this context and it is therefore important to increase knowledge about the potentials in the country for cultivating this crop. Sugar beet trials conducted in Nyandarua and Butere Mumias Districts of Kenya have shown that the crop yields are comparable to those obtained in traditional sugar-beet cultivation regions of Europe. Since sugar beet yield is affected by climate and soils, the results of Nyandarua and Butere Mumias sugar beet trials are not adequate to propose that comparable yields can be obtained elsewhere in the country and other tropical regions. Physical land evaluations assessing the potentials and constraints for sugar beet production are therefore essential. The objectives of this study was to develop a Tropical Sugar Beet Land Evaluation Scheme (TSBLES) that can aid assessment of the suitability of different areas in the tropics for sugar beet cultivation; and to test this scheme for an assessment of suitable sugar beet zones and land areas in Kenya. The development of the scheme was based on various literature sources and expert judgment on sugar beet requirements, and a Tropical Sugar Beet yield prediction Model. The TSBLES accounts for physical conditions of land i.e. climatic, edaphic and topographic conditions. According to the assessment results 27% of the land area in Kenya is suitable for sugar beet cultivation. Of this area, 5% is highly suitable, another 5% is moderately suitable and 17% is marginally suitable. Most of the highly suitable land area is concentrated in Rift Valley, Central and Nyanza provinces. The Rift Valley has the highest share of the suitable land area.  相似文献

Sedimentary and igneous rocks of the Swaziland Sequence of South Africa (>3,200 my. old) contain total carbon (0.09–8.28%), organic carbon (0.04–1.95%) and sulfur (9–53,000 ppm). Amounts of organic carbon are generally high in the lower part of the Sequence (based on two samples from the Theespruit Formation). Sulfur content varies widely with no obvious correlations or trends. These rocks may contain clues to the early carbon and sulfur cycles on earth.  相似文献

Inequality seems to be a feature of all societies, but some are probably more equal than others. It is in Third World countries however where inequalities between particular areas, groups and individuals are most marked. The paper first traces the growing interest in both the study of inequality and the rural household as a focus of analysis. Some of the problems of measuring inequality are then considered and various indicators of inequality are examined with reference to empirical evidence from rural W Africa. The paper concludes that recent development strategies have often directly or indirectly led to greater rural inequality and makes suggestions as to how future projects might achieve greater impact in reducing the gap between rich and poor.

Africa is a late comer in the field of industrial development and, today, trails considerably behind even developing Asia and Latin America in the contribution of manufacturing to GDP. At independence, African countries inherited a structural and spatial pattern of industries incapable of contributing to rural development and nationally integrated economies. The principal weaknesses of the structural and spatial patterns of industries are the predominance of first-stage processing and consumption goods industries and the lack of basic capital goods industries, the high degree of metropolitan concentration, the low and sometimes insignificant development of intersectoral and interregional linkages, the high capital-labor ratios, the growing balance of payments' problems caused by the heavy reliance on imported materials and equipment and the monopolistic control of output and markets fostering rising domestic prices. These limitations are discussed and the main ingredients of an alternative industrial allocation pattern outlined. The sustaining thesis is that any African country seeking alternative industrial allocation patterns calibrated to stimulating rural development and the integration of the space economy must initiate critical changes in the inherited structural and spatial patterns.  相似文献

This paper examines the importance of national-level institutional arrangements for promoting the EU’s Protected Geographic Indication scheme (PGI). Taking the example of Ireland, for which PGI designations remain comparatively low, it explores whether the approach to providing institutional supports to the PGI scheme is influenced by top-down technocratic governance structures that pertain to food safety and quality certification that encompass the broader operating environment for food production in Ireland. Although the regulation of food safety and quality certification are distinct remits to the administration of the PGI scheme, in the Irish context the same institutional bodies are involved in governance of both. Using a discourse analysis interpretative framework, this paper draws on interviews with Irish producer group members and institutional representatives to examine how governance of the PGI scheme reflects management perspectives and practices more in keeping with a regulatory environment for food safety and quality than with development of place-based food product links. It suggests that incentives to avail of the PGI scheme as a means of realising value-added for producers are not well established because they require the development of more subjective, context-dependent processes and practices linked to geographical place and place identity. These are not easily accommodated under current institutional arrangements that also incorporate food safety and quality remits because these are in turn strongly established through nationally and internationally recognised systems of regulation and benchmarking. The findings point to the benefits to be gained from a more layered governance structure for PGI; devolving operation of the scheme to relevant regional and local development organisations that possess the expertise and relevant local knowledge to (a) incentivise the formation of producer groups, and (b) prioritise mentoring and support for PGI concept development as a clearer reflection of bottom-up rural sustainability policy.  相似文献

Oman has a long tradition of practising handicrafts, though few are of high aesthetic value. Omani handicrafts have always been functional, made for a rural population which has valued the artefacts for what they do but much less for their appearance. Nevertheless, handicraft skills are very widespread throughout the rural population. In the past they have been used to process raw materials of agricultural origin, notably from the date palm and from livestock, and also from wild trees and minerals. In addition to local resources, Omani craftsmen have worked imported cotton yarn and imported precious and semi-precious metals. The craftsmen not only provided equipment for rural producers and finished goods for domestic use but they also performed the important community roles of linking primary producer with primary producer and consumer, and making both more aware of the raw materials of the environment in which they lived. In doing this, craftsmen, with their mutually respected skills, played a vital role in creating the complex network of interdependencies from which a community is built. However, the Omani and other regional oil industries put great pressure on all rural activities, and particularly on the highly labour-intensive crafts. People sought work in the urban centres and in the armed forces at the same time as a flood of cheap imports prevented craftsmen from raising their prices to keep abreast of inflation and of heightened personal material aspirations. The impact of oil was so rapid that the craftsmen had no time to adapt their techniques or their products to meet the new circumstances. Craft growth and change needed government support to see it through a difficult transitional period. Unfortunately, however, the government of Oman has only played a small and somewhat confused role in the crafts. Many people can no longer practise their inherited skills and the role that they played in maintaining the community has been largely destroyed. Concentrated effort needs to be made, craft by craft, initially at a village scale, to train and to modify techniques where necessary and to expand market openings. Success in a single village can then form the basis of expanded regional or national projects, drawing in other resources such as credit from the Agricultural Bank and using the marketing networks of the Central Marketing Authority. An approach which has been used to redevelop spinning and weaving and to introduce irrigation channel manufacture in a coastal village in northern Oman is providing valuable information that could be used as the basis of other craft projects in Oman and in countries with comparable craft development problems.  相似文献

The bimodal suite (BMS) comprises leucotonalitic and trondhjemitic gneisses interlayered with amphibolites. Based on geochemical parameters three main groups of siliceous gneiss are recognized: (i) SiO2 < 73%, Al2O3 > 14%, and fractionated light rare-earth element (REE) and flat heavy REE patterns; (ii) SiO2 and Al2O3 contents similar to (i) but with strongly fractionated REE patterns with steep heavy REE slopes; (iii) SiO2 > 73%, Al2O3 < 14%, Zr ~ 500 ppm and high contents of total REE having fractionated light REE and flat heavy REE patterns with large negative Eu anomalies. The interlayered amphibolites have major element abundances similar to those of basaltic komatiites, Mg-tholeiites and Fe-rich tholeiites. The former have gently sloping REE patterns, whereas the Mg-tholeiites have non-uniform REE patterns ranging from flat (~ 10 times chondrite) to strongly light REE-enriched. The Fe-rich amphibolites have flat REE patterns at 20–30 times chondrite.The Dwalile metamorphic suite, which is preserved in the keels of synforms within the BMS, includes peridotitic komatiites that have depleted light REE patterns similar to those of compositionally similar volcanics in the Onverwacht Group, Barberton, basaltic komatiites and tholeiites. The basaltic komatiites have REE patterns parallel to those of the BMS basaltic komatiites but with lower total REE contents. The Dwalile tholeiites have flat REE patterns.The basic and ultrabasic liquids were derived by partial melting of a mantle source which may have been heterogeneous or the heterogeneity may have resulted from sequential melting of the mantle source. The Fe-rich amphibolites were derived either from liquids generated at shallow levels or from liquids generated at depth which subsequently underwent extensive fractionation.  相似文献

The idea of territorial integration can be seen as a basic concept in the recent, loosely defined ‘neoregionalist’ approach to spatial policy and planning. Lying between a social Utopia and various methods or doctrines of regional science, this idea has no coherent theoretical basis at all. This problem will be approached here from the geographical viewpoint, i.e. from the point of view of the concept of territoriality. This aim is to avoid abstract conceptualization and instead to arrive at a concrete reality, primarily the reality of the Scandinavian countries (as one of the intellectual contexts of neoregionalism). Instead of physical unit, i.e. territory, a more interesting starting point is to consider territoriality as a socio-spatial concept. Thus, instead of the abstraction of region, the focal point would be the locality as a basic element of the multi-level settlement and community structure, i.e. as the arena for everyday life (way of life) of a community. Problems of local interest may then be discussed in relation to national and/or class interests. Thus the basic dialectic opposition can be seen to exist between the structural realities of the global economy and local action. The essential intermediate level between them is the nation-state, while the region as a kind of subnational level is conceptually and strategically a problematic unit.  相似文献

This paper attempts a conceptual clarification of the term development in a national or regional context. It emphasizes the integrative and systemic nature of, as well as the underlying principle of social justice in, meaningful development efforts. Illustrating with a part of the Nigerian rural environment, the paper shows how certain problems of the rural communities can have region-wide, if not nation-wide, implications. The policy issues for effective remedial measures are outlined, and their effective implementation is shown to depend very much on carefully undertaken problem and resource evaluation and streamlined inter-disciplinary co-operation.  相似文献
