Supporting local government administrations through public private partnerships (PPP).

In a decentralised framework, local government is generally charged with the responsibility of delivering basic services to its constituencies, and for this system to work, local government entities are also given the right to raise their own revenues. The revenue from land & property tax is necessary if local government wants to achieve financial viability.
With the support of the WB, many governments have modernised their Land Information Systems, creating the platform for local government to collect property taxes. However, the failure of the vast majority of local governments to efficiently collect the property tax means that it is necessary for the private sector to provide support. Local governments undoubtedly need help to implement land & property tax systems.
This paper outlines practical and tangible measures of how innovation and collaboration with the private sector can help local government to be more successful in raising their internally generated revenue (IGR).
Land characteristics survey in Korea, utilizing spatial information
Jinho Choi, Nana Lee
Korea Appraisal Board, Korea, Republic of (South Korea)
The purpose of this presentation is to show how the land characteristics survey method of Public Land Price Assessment System (PASLP) of the South Korea developed by applying spatial information science, with specific examples.
The Korea Appraisal Board developed the Automatic Land Characteristics Survey (ALCS) System with its own GIS and information technologies in order to enhance the accuracy and efficiency of land characteristic survey with less survey error.
By using geospatial technology, the said automated survey system of land characteristics influences pricing of land. It is especially used to analyze topography, parcel shape, aspect, road adjacency, area, zoning, land use, planning and accessibility to land parcels for public facilities. It allows quick and accurate field surveys of each land parcels throughout the country, improving time efficiency and saving human labor. Moreover, it enhances the accuracy, objectivity and consistency in field surveys, saving the cost of field surveys.
Cost-Effectiveness Analysis of a satellite–based approach to maintaining a property database
Graham Deane, Robert M Owen
Airbus Defence and Space, United Kingdom
Maintaining up-to-date and accurate information about all assets and services owned and operated by organisations is essential for good governance. Often insufficient attention or resources are provided to ensure this occurs and in rapidly changing environments, such as exist in the developing world, where increasing urbanisation is a major factor, information about land and property is all too often inaccurate, considerably out of date and not maintained in any meaningful way. The change detection project in Dakar, which uses the analysis of Very High Resolution satellite imagery to identify urban change, provides a means to keep the database of land and property up-to-date at reasonable cost. However it is only of benefit if, upon the completion of a Cost-Effectiveness Analysis (CEA), the method adopted is demonstrably shown to be carried out at a lower cost than the alternative approaches, such as a field-only based approach.
The points-based method: simplification of valuation processes for property tax purposes
Asaah Nyah Zebong, Wilson Prichard, Paul Fish
International Centre for Tax and Development (ICTD), Cameroon
It is widely acknowledged that property taxation systems in much of sub-Saharan Africa are severely underperforming due in part to ineffective valuation. The paper discusses the importance of simplifying valuation in contexts where property markets are inexistent, institutional flaws are rife and valuation rolls are incomplete. Drawing on experiences from Sierra Leone, Malawi and Senegal, it argues that simplified valuation like the Points-Based Method (PBM) are easier to administer and particularly more attractive options in resolving challenges linked to the more traditional market and surface area methods. Outcomes of the implementation of iterative processes of PBM clearly show that the method is: flexible, transparent and ensures efficient coverage of wider areas. It mimics market price trends and is easily managed using simple ICT systems. Therefore, a strong empirical case exists to take progressive medium-term steps to substitute traditional with more simplified methods that improve chances of optimizing property tax yields.
