Fragmented agricultural land raises the costs of agricultural production. The land fragmentation manifests as a large number of relatively small and spatially divided land parcels of each owner. Additionally, the parcels are often very irregular in shape, which hinders an effective application of modern agricultural machinery. A land consolidation procedure, i.e., regrouping and merging partitioned agricultural land into larger and more regular parcels, and simultaneously arranging road and canal networks, enables a significant improvement in the conditions of agricultural production. The basis for conducting land consolidation is the legal framework. Multi-annual and annual plans are to specify priority areas for conducting consolidation. These plans should take into consideration the costs and benefits of land consolidation. To ascertain this, it is necessary to determine areas suitable for consolidation and express their qualitative features in a quantitative manner. The aim of this paper is to explore possibilities of using the official registers' data to broad selection of land consolidation priority areas. To rank the chosen spatial units, various indicators have been selected and calculated at the state level. Multi-criteria analyses are commonly used as a tool for selection of the optimal solution scenario, using possibly conflicting indicators and measures. The paper used three different multi-criteria methods to determine Cadastral municipalities rankings. These rankings could be used by national agricultural or other spatial planning agencies to increase transparency and effectiveness through information-based decision making.

The paper presents a conceptual model for the disposition of state agricultural land. The model is made as an extension of the Croatian Land Administration Domain Model (LADM) country profile. The LADM 19152:2012 is an International Organization for Standardization (ISO) standard which provides a formal language to describe the basic information-related components of land administration. The aim of this research is to assess the possibility of using the LADM extension to efficiently manage state-owned agricultural land. Since more than half of state-owned agricultural land in Croatia is not activated, the priority is to increase usage and activate uncultivated agricultural land by users through disposition process. The disposition process is highly regulated and complex in procedures, and it poses difficulties for organizations in the implementation of disposition, so a model of successful management is necessary. The disposition process and the necessary steps are shown—mainly defined by legal regulations—and divided into two phases: the first phase is the development of the Program of Disposition of State-Owned Agricultural Land where the multi-criteria decision analysis (MCDA) for land potential analysis is crucial; the second phase is the realization of the disposition. In line with the disposition process, a Unified Modeling Language (UML) model for this LADM extension on the conceptual level was developed and is presented herein. Finally, the improvement of the agricultural land management system and the related processes are reviewed.

The article presents the results of the analysis of the legal and practical aspects of the implementation of land value maps for land consolidation in four countries: Slovakia, Croatia, Poland and Turkey. The discussion indicated that it is not possible at present to construct fully universal methods of automatic earth valuation for LC. The reason is that there are too many different approaches to land value mapping. Identification of areas with similar characteristics (valuation factors) needs to be conducted prior to valuation of individual parcels. In both cases, the agronomic value from the farmer’s point of view is the key valuation criterion. It was pointed out that achieving versatility of algorithms can occur only as a result of extensive parameterisation of the developed models, both in terms of the number of factors considered, as well as the manner and strength of their interaction. The development directions of land valuation mass methods should proceed with the widest possible scope of public participation determining the principles of this valuation, which increases the level of acceptance of both the result of the land valuation itself and the subsequent effects of the land consolidation project.
