AbstractThe article is a comparative study of Mycenaean Greek and Hittite land-tenure systems. It is based upon a systematic comparison of two groups of documents: land-registers (the so-called E-series) from Pylos and Middle Hittite land-donations. The traditional interpretation of both Mycenaean Greek and Hittite documents is challenged and alternative interpretations are offered. Thus, on the Mycenaean side, the construction with the preposition pa-ro is reinterpreted, and on the Hittite side an entirely new interpretation of a Hittite expression pir-sahhanas is offered. Both land-tenure systems are interpreted as two manifestations of compulsory labour service of small landholders attached to large agricultural estates. Cet article est une étude comparative des systèmes de tenue de la terre dans la Grèce mycénienne et l'empire hittite. Elle est fondée sur une comparaison systématique de deux groupes de documents : les registres de la terre (appelés la série E) de Pylos et les donations de terre moyenne hittite. L'interprétation traditionnelle des documents mycénien et hittite est ici remise en question et une nouvelle explication est offerte. Ainsi, du côté mycénien, la construction avec la préposition pa-ro est réinterprétée, et du côté hittite une interprétation entièrement nouvelle de l'expression pir-sahhanas est proposée. Les deux systèmes de tenue de la terre sont interprétés comme deux manifestations d'un service de travail obligatoire dus par des petits propriétaires attachés à des grandes propriétés agricoles.

Structural Types

Four structural types of cerrado vegetation were examined to test the following hypotheses: (1) there are predictable changes in woody plant density, species richness and life-history strategies from one structural type to another; and (2) plant species composition in the less-rich structural types represent particular and impoverished subsets of those found in the richer ones. The study was conducted at Fazenda Palmares (5°33′S, 42°37′W) Piauí State, Brazil. A 47% decrease in woody plant density between cerradão (forest) and the least-dense type of cerrado sensu stricto (scrub) was associated with a 40% decrease in species richness. The percentage of lower-layer species was reduced by 29% in the least dense type of cerrado sensu stricto compared to cerradão. The proportion of species that flower and fruit during the rainy season was also reduced by one third. Species were not distributed as impoverished subsets along the cerradão–cerrado sensu stricto gradient. It is argued that the reduction in woody plant density and richness is partly due to factors limiting the occurrence of species with particular life-history strategies. The species composition of structural types is affected by the ‘mass effect’ and also by surrounding biotas, which provide species that colonize particular types of cerrado vegetation. Both these processes reduce the likelihood that the species composition in the poorer structural types are simple subsets of those present in the richer types.

Land Tenure Systems

Land registration processes have been described to be simplistic in simple land tenure environments where land rights are treasured and registered by the state on behalf of the people. Duplication of tasks, repeated preparation of land registration documents, and wrong definition of tasks affect the activities and processes of land registration characterising complex land tenure environments. Many qualitative land registration models such as the use of Unified Modified Language (UML) diagrams have been developed to show the frameworks of land registration processes in most parts of the world. However, most researches avoid the technical implementation of these models. This paper presents the quantitative approaches to addressing the problems of land registration processes in complex land tenure systems using computational techniques such as Process Maker and Java Script. The paper used case study approach to collect data and systems design method for the output. Semi-structured interviews were used to collect data from the Lands Commission of Accra and its stakeholders. Process maker software was operationalised using GeoJSON parcel file. Results show that, the simplification of land registration processes is based on the rationale behind the change (Data error, improved capacity, service quality), and the semantics (process re-engineering) involved in the computation of the modelling processes. The outcome has the ability to simplify an otherwise complex tenure system by avoiding delays and therefore improving the land registration processes.

Land Tenure Systems

Women have less access to land than men in Africa. Previous analyses have typically identified African indigenous culture as the problem’s exclusive source. With Cameroon, Kenya and Sierra Leone as empirical referents, an alternative explanation is advanced. Here, the problem is characterized as a product of Africa’s triple heritage, comprising three main cultures, viz., African indigenous tradition, European/Christianity and Arabia/Islam. The following is noted as a major impediment to women’s access to, and control of, land: the supplanting of previously collective land tenure systems based on family or clan membership by ‘ability-to-pay’ as the principal determinant of access to land.
