Many Asian mega-cities are growing rapidly and they face formidable urban problems: unplanned squatter settlements, inadequate infrastructure and basic amenities. Smaller Asian urban areas also need badly the provision of basic infrastructure and facilities. However, efforts to improve are often constrained by either nonavailability of suitable land or its exorbitant cost. Strategies such as land consolidation have shown considerable promise. Implementation of the strategy varies from country to country and from project to project. In general, the land consolidation approach is participatory in nature and places emphasis on in situ development with voluntary contribution of private assets by affected households in need of infrastructure and basic services. However, to make any significant impact of the land consolidation strategy on urban development, financial support from multilateral agencies such as the World Bank is necessary. To enable this it is necessary that the policy and implementation procedures fully conform to the objectives of the World Bank's safeguard policies such as OD 4.30 `Involuntary Resettlement'. This study reviews the land consolidation policies and procedures as applied in several Asian countries in general, and in Indonesia in particular. The objective is to identify the gaps that exist between the policy and procedures and that of the objectives of the World Bank's Policy of Involuntary resettlement and to recommend general policy and procedural guidelines for land consolidation projects that would enable financial support from multilateral agencies such as the World Bank. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Forced resettlement, central to state-led development throughout the twentieth century, still paves the way for agroindustrial, hydroelectric, urban, and other forms of development in much of the global South today. In response to pressures from social movements challenging human displacement, states, firms, and multinational institutions increasingly seek the consent of impacted communities, often offering monetary compensation and resettlement, along with development assistance. Some states obtain consent by offering resettlements with urban infrastructures and public services. In Ecuador, the state has planned 200 urban-like resettlements called “Millennium Cities” for communities on the Amazonian oil and mining frontiers. Although resettlement in this context transforms human–environment relations and generates new social ills by isolating residents from food supplies and market networks, many communities do consent to resettlement. In this paper, I call attention to voluntary rural–urban resettlement in land grab governance and I explore why communities might consent to their own displacement. This paper suggests the need to account for the material and social conditions that structure consent.  相似文献

ABSTRACT

The relationship between climate change and human displacement is an important topic of global concern. China is a special case due to a high level of government control enforcing the ecological migration of millions of people since the mid-1980s. Little research has addressed how resettled people adapt to climate impacts in ecologically vulnerable resettlement areas and what factors influence their intentions to relocate again or adapt locally. Employing a social-ecological system approach, this study builds a conceptual econometric framework which differentiates two steps that drive migration intention at the household level. The study uses this approach to examine the role of both contextual and household factors in motivating the migration intentions of resettled people in the largest environmental resettlement area of Ningxia Hui Autonomous Region, China, where household survey data were collected in 2012. This framework enabled an analysis, first, of how local contextual factors and household factors shape the severity of climate impacts on households and, second, how these factors interact with the experience of climate impacts to further influence a household’s migration intention as a response to climate impacts. The results show that some contextual factors (such as limited use of water-saving techniques, little practice of cultivating aridity-resistant crops, and lack of government support), strong local social networks and being in receipt of low rates of financial remittances have significant associations with adverse climate impacts experienced by resettled households, and also with their anticipated further relocation to respond to these impacts.  相似文献
