Gender equality and poverty in Ghana: implications for poverty reduction strategies     

Mariama Awumbila 《GeoJournal》2006,67(2):149-161

Poverty trends in Ghana show a decline over the last two decades. However, the period also shows evidence of the intensification of vulnerability and exclusion among some groups, including women. Among several variables accounting for women’s vulnerability to poverty are gender inequalities, which it is argued, undermines development and the prospects for improving standards of living. Therefore it has been suggested that policies, which aim at reducing poverty and promoting sustainable development must integrate gender equality, equity and women’s empowerment in its goals. Despite these, the interconnections between a reduction in gender inequality and a reduction in poverty are complex. The paper explores the gender dimensions of poverty in Ghana, and how gender inequalities are manifested and implicated in the reproduction of poverty. It also assesses the extent to which these have been taken into account in poverty reduction strategies and policies to enhance the situation of women. It concludes that if strategies to engender poverty reduction programmes are to be sustainable it is important to recognize unequal gender relations and the structures of power that women confront at all levels in Ghana and how these increase women’s vulnerability to poverty.  相似文献   

Managing sustainable farmed landscape through 'alternative' food networks: a case study from Italy   总被引：1，自引：0，他引：1  

LEWIS HOLLOWAY  ROSIE COX†  LAURA VENN‡  MOYA KNEAFSEY‡  ELIZABETH DOWLER§  HELENA TUOMAINEN§ 《The Geographical journal》2006,172(3):219-229

This paper focuses on a case study of an 'alternative' food network based in the Abruzzo National Park, Italy, to explore how ideas of sustainable farmland management can be expressed through broader understandings of developing networks of care concerned with local economies and societies, high-quality specialist food products, particular 'traditional' farming practices and livestock breeds, as well as the ecology of a farmed landscape. The scheme allows customers, internationally as well as in Italy, to 'adopt' a milking sheep on a large mountain farm. In return, adopters are sent food products from the farm. The adoption scheme is inter-twined with an agri-tourism project which provides accommodation, runs a restaurant and engages in educational activities. The scheme is the result of the individual initiative of its founder, and is associated with a strongly expressed ethical position concerning the value of sustaining valued local rural landscapes and lifestyles, and the importance of 'reconnecting' urban dwellers with rural areas, farming and 'quality' food production. Yet the localness of the scheme is sustained through wider national and international networks: volunteer and paid workers are drawn from several European countries, funding has been acquired from the EU LEADER programme, and internet and transport technologies are essential in connecting with and supplying an international customer base. The broader economy of care instanced in this case study draws attention to a need to develop strategies for sustainable farmland management constructed around wider programmes of social, economic and cultural, as well as environmental, concern.  相似文献

Site Investigation for the Effects of Vegetation on Ground Stability     

John R. Greenwood  Joanne E. Norris  Jo Wint 《Geotechnical and Geological Engineering》2006,24(3):467-481

The procedure for geotechnical site investigation is well established but little attention is currently given to investigating the potential of vegetation to assist with ground stability. This paper describes how routine investigation procedures may be adapted to consider the effects of the vegetation. It is recommended that the major part of the vegetation investigation is carried out, at relatively low cost, during the preliminary (desk) study phase of the investigation when there is maximum flexibility to take account of findings in the proposed design and construction. The techniques available for investigation of the effects of vegetation are reviewed and references provided for further consideration. As for general geotechnical investigation work, it is important that a balance of effort is maintained in the vegetation investigation between (a) site characterisation (defining and identifying the existing and proposed vegetation to suit the site and ground conditions), (b) testing (in-situ and laboratory testing of the vegetation and root systems to provide design parameters) and (c) modelling (to analyse the vegetation effects).  相似文献
