- the need of more decentralized decision-making, of a more important role in decision-making for the parties concerned and of a better legal protection of their rights. The planning procedure for each project under the rural land development bill consists of two phases. In the first phase a more or less abstract plan (programme) is drawn up and in the second phase a more detailed plan is made. Both, the program and the more detailed plan, have to be confirmed by the regional government. Program and plan have to be in accordance with physical planning on the regional level. The decision about whether to carry out a project or not is taken after the program-phase. The bill contains the rules and procedures for four types of rural land development: - Reconstruction, which can be used in rural areas with to a large extent non-agrarian purposes. The decision to carry out a project has to be taken by the regional government. Reconstruction needs not to include re allocation or may include re-allocation only in a part of the reconstruction-area. Within this type of rural land development the expropriation of land in accordance with the public interest is allowed. If re-allocation takes place, 3 per cent (maximum) of the area, that under goes re-allocation, can be used for the construction of roads and watercourses and provisions which are con nected to them. - Land consolidation for areas with mainly an agrarian purpose. The decision to carry out a land-consolidation project has to be taken by the owners and tenants by means of voting. To a maximum of 5 per cent of the land can be used for the construction of roads and water courses and provisions that are connected to them, for provisions which are in the interest of nature and land scape and for other provisions which are in the public interest. Land-consolidation always includes re-alloca tion in the entire land-consolidation-area. -Adaptive land development, which combines rural land development with the realization of an important infrastructural object (for instance a motorway). The decision about the execution of a project has to betaken by the regional government. To a maximum of 3 per cent of the area can be used for the construction of roads and watercourses and the provisions that are connected to them and for provisions in the interest of nature, landscape and open-air recreation. This type of rural land development includes re-allocation of the land. - Land-consolidation by agreement, the well-known simple instrumentto improve the agricultural situation for a limited number of farmers. Reconstruction and land-consolidation are the most im portant types of rural land development and the gradual planning process applies only to these types. The proce dure of these types consists of the following steps: - application for rural land development; - placing a project on the national planning scheme for rural land development and appointment of a local committee; -drawing up of the project-program (more or less ab stract planning) and decision-making; - detailed planning; - execution of the plan. The re-allocation takes place in the execution-step. The re-allocation procedure includes: NGT GEODESIA 82 -valuation of the parcel and investigation of the rights and the rightholders; fixation of the plan of the boundaries of the roads, watercourses and non-agricultural provisions; - investigation of the wishes of the parties concerned with respect to the re-allocation plan; drawing up of the re-allocation plan and the re-alloca- tion deed; - financial arrangements. To carry out a project and particularly the re-allocation process successfully it is very important for the local committee to have several hectares of land at its dispo sal. This land is usually provided by a special foundation supported by the government that buys the land from farmers who stop farming. This land can be used to facilitate the parcelling by making it possible to project the new parcel boundaries along existing topographic lines. Some of this land can also be used to compensate forthe proportional part of the land that each ownerand tenant, according to the projectplan, has to cede in the interest of new roads and watercourses, landscapebuild ing and conservation of nature. It is customary that some of this land is used for the realization of landscape-build ing within the framework of the re-allocation plan. Technical aspects To facilitate the drawing up of the re-allocation plan the Cadastre (ir. R. van der Schans) has developed an auto mated system, which is called the ATOR-system (ATOR stands for automation of the design of a re-allocation plan for land-consolidation). By this system the admini strative and arithmetical operations in the initial phase of the re-allocation processaretoa large extent automated. As it is not a fully automated system, it meets in a reasonable way the need to consider the characteristic data of the individual farmings during the re-allocation process. In brief: the system delivers the sizes of the new parcels andtheircomputed positions, whereas the input consists of the sizes of the new parcels and for each parcel a couple of alternative positions. Ir. W.H. de Vos has put forward a paper on this subject at the meeting of commission-7 during the 1981 FIG-congress at Montreux. The system has proved to show the following advan tages: more objective weighing of the claims of the individual farmings; more adequate involvementof rural land development policy in the re-allocation process; - shorter processing time; - more accurate processing and more reliable output. The system has also proved to be very useful for a study of the re-allocation possibilities in the planning phase of a rural land development project. So far the system has been used in about 60 projects. By ing. R. Kik (Instituut voor Cultuurtechniek en Water huishouding; Wageningen) a re-allocation system has been developed based on linear programming. This sys tem has the advantage that it operates more quickly. Its disadvantage is that it does not meet sufficiently the need to consider the characteristic data of the individual agra rian establishments. The system is useful at the early start of the planning process. Recently ir. Chr. Lemmen (University of Technology; Delft) developed a new automated re-allocation system that promises to be even more useful than the ATOR- system because it is able to compute the optimum size of 215
