The tool presented in this guide aims to assist policy-makers and land administrators to adopt appropriate technologies and methodologies for land administration services more efficiently, cost effectively and with options most appropriately tailored to national and sub-national contexts. It was developed after recognizing the need to modernize the budgetary approach to land agencies and to provide effective, cost-efficient, affordable and sustainable services, particularly in developing countries. Countries seeking to modernize land administration services often face large and immediate costs to first achieve broad geographic coverage, and then to establish the supporting records, procedures and personnel capacity.
