Ethiopia has implemented one of the largest, fastest and least expensive land registration and certification reforms in Africa. While there is evidence that this ‘first-stage’ land registration has had positive effects in terms of increased investment, land productivity and land rental market activities, the government is now piloting another round of land registration and certification that involves technically advanced land survey methods and computer registration. This ‘second-stage’ land registration differs from the registration system employed in the first round that used field markings in conjunction with neighbors’ recollections to identify plot borders. We use panel data from 600 households in southern Ethiopia to investigate household perceptions of and demand for such a new registration and certification. Our study revealed relatively low demand and willingness-to-pay (WTP) for second-stage certificates. The WTP also decreases significantly from 2007 to 2012. Our findings indicate that farmers do not believe that the second-stage certificate enhances tenure security relative to the first-stage certificate except in instances in which first-stage certification was poorly implemented. The demand for second-stage certificates appears to come primarily from governmental authorities, as it can provide a better basis for land administration and produce accessible public documentation of land-related affairs.  相似文献

Individualization of tenure through title registration programmes introduced in many African countries after independence with the promise of security of tenure and increased agricultural productivity has, instead, had the opposite effect. Informal land arrangements continue to emerge as a result of the slow pace of land adjudication (formalization) and updating of land information systems. The trend towards computerization of land information systems has only put focus on already existing formal land tenure arrangements, leaving out the informal social tenure arrangements. As a result, there are now many efforts worldwide motivated by the introduction of the Social Tenure Domain Model (STDM), and freely-available and easy-to-use technology tools to identify, document and map land in support of informal land administration arrangements. Actions are made towards the use of community-generated information to support land administration. Using theories from the interplay between formal and informal institutions, this paper discusses the potential outcomes in adopting Volunteered Geographic Information (VGI) in land administration in Kenya. Two case studies are presented that demonstrate the complementary-accommodating, versus the substitutive-competing approaches. These are then compared with the formal land adjudication process in Kenya. It is established that because of the direct involvement of the national mapping agency in land adjudication where VGI is utilized, the outcome is a case of formal adoption of VGI, while in the other case, where there is little or no involvement by the national mapping agency, the outcome is more of competition and substitution. The latter is an example in which the VGI is used just like any other information to inform policy making, rather than taking it as the authoritative source. We argue that since informality is – and will always be – part and parcel of land administration in many African countries as a result of ingrained social relations and power structures, adopting crowdsourced land information into existing formal land administration systems should consider the particular land administration process, satisfying innate demands and requirements, thus re-engineered to accommodate VGI.  相似文献

Summary

The paper commences by describing the statutory basis for land tenure and management. It examines the constitutional basis for land ownership and occupation rights, as amended by land administration law. The legal system and procedures at both central and local government level are introduced, with particular mention made of the special measures for land requisition. This is followed by a study of the organizational structure for land management in China at state and local government levels. The roles and responsibilities of the major agencies of government at both levels are explained, and related to the organization of urban planning. A separate section is then devoted to those areas such as Special Economic Zones and Open Coastal Cities which have been selected for preferential treatment, particularly in respect of the transfer of land use rights.

The paper concludes with a study of the main issues and problems that currently confront China in the field of urban land management. And some suggestions are made where further reform is required and additional research of potential benefit.  相似文献

行政管理学是一门不断发展的学科,"公共行政学"和"公共管理学"不能称之为独立的学科,只是行政管理学发展的历史阶段中的不同表现形态."公共行政学"和"公共管理学"的提出抹杀了行政管理学的阶级属性,只会迎合西方资产阶级的愿望.  相似文献
