The global idea of building state Land Administration Systems was to determine the infrastructures for the implementation of land policies and land management strategies in support of sustainable development. This new paradigm in science has directed many studies towards the development of concepts for the integration of various spatial information systems in the framework of interoperable infrastructures. Each infrastructure includes institutional arrangements, a legal framework, processes, standards, land information, management and dissemination systems, and technologies required to support allocation, land markets, valuation, control of use, and development of interests in land.Many countries are in the process of developing Land Administration Systems (LAS). Databases of Land Information Systems (LIS), including cadastres, land registries, tax registries and land-use plans, are integrated to improve Land Information System functions and provide effective support for other systems and economic processes.This article analyzes the LAS construction process in Poland with particular emphasis on the functionality of the infrastructure supporting the widely understood sustainable development of land, the economy and society. The presented solution may be an important model (template) for other national infrastructures.

The improvement in a regions’ accessibility that accounts for various means of inter-regional transport and inter-regional communication is one of the main determinants of sustainable regional development. This study focuses on road accessibility in rural areas where an insufficient number and scope of international and domestic investments can lead to an imbalance in the transport infrastructure. Therefore, the aim of this study was to evaluate road accessibility at the level of the NUTS4 units in view of their sustainable development and their divergence from rural units that are less distant from the main transport routes. The studied area—a province—is situated in the northeast of Poland. Data concerning the travel time, condition, and density of the road network were analysed to develop and compare the measures of road accessibility in individual units and to perform an overall assessment of the NUTS4 units. Partial indices were calculated with the support of the QGIS and ArcGIS software. Peripheral regions in post-socialist countries appear to be particularly underinvested in terms of the transport, including at the local and regional level. The applied methodology supported the presentation of problem peripheral areas that are underinvested and threatened with exclusion.

Sustainable rural development (with the development of social functions) is currently one of the basic objectives of the rural areas policy in Poland. The main purpose of this article is to determine the level of social development of rural areas and to examine whether the National Support Center for Agriculture (NSCA) activities (in the form of transferring land to communes for the implementation of social goals) have an impact on that development, and to what extent. In this article, an assessment of the social development level of rural areas using the Hellwig method was carried out. The research covered the years 2005 and 2018, on the districts of the Warmian-Masurian voivodship located in the northeastern part of Poland. The detailed analysis also covered the rural and rural-urban communes of Lidzbark, Kętrzyn, and Bartoszyce districts. The obtained results were compared with the area of land transferred by the NSCA Regional Office Olsztyn to local government units in 2004–2017, for the implementation of social goals. Pearson’s correlation coefficient was used for a comparison. The results are presented in tabular form and visualized using GIS software in the form of carto-diagrams (diagram maps). Results show a positive influence of NSCA on social development of rural areas.
