This chapter studies the development and the evaluation of the land fragmentation model, LandFragmentS (Land Fragmentation System). The aim of this module is to quantify the existing situation of land fragmentation using a new index that measures the efficiency of the existing land tenure system and may assist planners in policy decision making, i.e. it can help to decide whether land consolidation should be applied. The chapter contains four main sections. Specifically, the first Sect. 7.2 presents significant aspects of model structure, namely, the methodology for developing the new index, the definition of land fragmentation factors involved in the model, a new method called ‘qualitative rating’ for assigning weights to factors and standardisation. Thereafter, the module interface is presented in Sect. 7.3 that sequentially follows all the steps for running the model, including the introduction of a new standardisation process called the ‘mean standardisation method’ (mSM). Then, a new ‘parcel shape index’ (PSI) is outlined in Sect. 7.4, which also includes a review of existing parcel shape indices. In Sect. 7.5, an application of the module is presented using a case study involving the investigation of four weighting scenarios, a comparison of the new index (GLFI) with existing indices, a sensitivity analysis focusing on changes to the weights and a comparison of the new PSI with existing indices.
