Agricultural land use alternatives in regional planning : a case study of West Pasaman area development planning West Sumatra, Indonesia

Pandjaitan, Sarda Vincentius January 1982 (has links)
This thesis investigates the problems involved in determining the appropriate use of agricultural land in its relation to regional planning. For the purpose of this investigation, the West Pasaman Development Plan has been chosen as a case study. The Development Plan for West Pasaman was drawn up by the Institute for Development Research--IDR, a consulting firm from West Germany, in 1975. The study team proposed five crucial projects to be developed within a ten year period (1975-1985). Two of these five projects, i.e., a new main road and an oil palm smallholder scheme were given priority. The priority for the oil palm smallholder project was based upon conventional economic criteria. Two important aspects were ignored. First, the physical characteristics of the site, including water resources, were not assessed, and secondly the needs of the existing population were not considered. In this thesis, three factors, the physical characteristics of the site, the social aspects of the population and economic feasibility were chosen as the criteria to determine the appropriate use of the agricultural land. The area of investigation is made up of two parts. The first part of 13,000 hectares is government land which, at present, is underutilized. The second part, consisting of 11,000 hectares, is private and communal land run by smallholders. The study team's report failed to account for the existing land use of this 11,000 hectares and therefore it is on this area, of land that the investigation has concentrated. It is found that the land being studied is physically suitable for rice cultivation. Oil palm cultivation does not appeal to the farmers in the study area because they are unwilling to move into new cultivation practices as they feel safer growing rice and other crops with which they are familiar. It seems an irrigation project is the most desirable government project for the study area. This would appear to confirm Indonesian national goals, which emphasize self-sufficiency in food production. If the available water resources of the study area (the Batang Tongar River) could be fully utilized, it is found by using economic data on returns per hectare per year, that double cropping rice with new high yielding varieties would yield a higher return to the farmers than oil palm. Thus, it is concluded that wet rice agriculture (double cropping) would be a more effective use of the 11,000 hectare area than oil palm. The thesis emphasizes that the physical characteristics of the site and the social aspects must be considered in determining the appropriate use of agricultural land in addition to the economic criteria. The thesis concludes with the discussion of the methodological limitations of the study and makes a plea for regional planners to utilize some of the new ideas of "development from below" and integrated regional development / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

Homesite severance policy: its evolution and impact on the agricultural land base of British Columbia

Collins, John Martin 05 1900 (has links)
The Homesite Severance Policy of British Columbia’s Agricultural Land Commission permits the subdivision of the farmer’s home from the farm property. Its purpose is to balance the protection of the agricultural resource with fair treatment for retiring farmers. This study documents the land use implications of the policy as well as its development, charting its origins and changes over the decades. Critics of the policy have noted two major problems. Urban sized lots have been scattered throughout the agricultural community, increasing the possibility of urban - rural conflicts (over the noises and smells of farming). Scarce arable land has also been lost, through construction (of the home or barns), on the remnant property. To determine if the agricultural resource has been compromised by the policy the frequency, location and actual area taken by homesite severance will be reviewed. In addition the study will explore the rationale and results of the two reviews of the policy. Suggestions will be offered (as they emerge from the findings and discussion) to alleviate the negative effects of the policy.

Decision support systems for land evaluation : theoretical and practical development

Miller, David B. January 1985 (has links)
The challenge of resolving land use allocation and policy questions depends to a large degree on the conversion of data into information, and the effective integration of information into the decision process. Land evaluation is one of the fundamental means of generating information for land planning. Information products have however, been inconsistently and ineffectively used in the decision process. This thesis develops a decision centered approach to land evaluation as a response to this concern. Included in this development is a description of important theoretical concepts, as well as a practical demonstration of the use of decision support systems as a design approach. Initially, a conceptual model is introduced illustrating the technical and use components of information generation, as well as the adaptive design cycle. Various terms and techniques involved in the technical aspects of land evaluation are reviewed. Decision making concepts including decision structure, environment, analysis, and criteria are outlined. Three existing methods of land evaluation are then compared from a use or decision making perspective. Having completed a review of current approaches, Decision Support Systems are introduced as a logical progression towards a decision centered approach. Decision Support System design is demonstrated using a portion of the Central Fraser Valley Regional District as a case study area combined with an interactive microcomputer land planning tool (LANDPLAN). The demonstration emphasizes the advantages of the flexible, interactive capabilities of Decision Support Systems in aiding the decision process. Iterative design is also promoted with several needs identified if a more complete system is to be developed. In particular, data on strategic long term supply and demand factors is required, as well as continuous rating functions for assessing land performance. / Science, Faculty of / Resources, Environment and Sustainability (IRES), Institute for / Graduate

O uso indiscriminado das terras, sem levar em conta suas potencialidades (tipo de solo, declividade, clima) é uma das principais causas da degradação do solo, erosão e perda de sua capacidade produtiva. A avaliação da aptidão agrícola de uma localidade é uma importante ferramenta, podendo subsidiar trabalhos sobre planejamento agroambiental e gerenciamento ambiental. O objetivo deste trabalho é comparar a base de dados de um Sistema de Informações Georeferenciadas (SIG) e um Sistema de Suporte a Decisão (SSD-SE), visando o planejamento da Microbacia Hidrográfica do Córrego do Jardim, no município de Santo Antonio do Jardim -SP. Os resultados adquiridos na Classe de Capacidade de Uso foram diferentes nas comparações entre as classes, mas quando estas mesmas classes foram reunidas em conjunto, o resultado foi semelhante. O SIG e o Sistema Especialista classificaram aproximadamente 40 % no Grupo B, de áreas adequadas para pastagem e reflorestamento e tiveram resultados divergentes para o Grupo A, adequada para utilização com cultura anual e cultura perene e divergente também para o Grupo C, que devem ser usadas para preservação ambiental. A adequação, quanto ao uso do solo não, teve diferença significativa, obtendo resultados por volta de 45 % da área da Microbacia sendo utilizada de forma adequada e 47 % com uso inadequado. Como resultado do Sistema de Suporte à Decisão e do Sistema de Informações Georeferenciadas, foi elaborado um plano de conservação para a microbacia, levando-se em consideração a sustentabilidade dos recursos ambientais. / Abstract: The need for soil conservation and preservation in agricultural areas is very important, because when they are gone environmental problems start to occur. The indiscriminate use of land, without any regard for its potentialities (type of soil, declivity, and weather) is one of the main causes for soil degradation, erosion and loss of productive capacity. The agricultural aptitude evaluation of a location is an important tool, being able to produce papers on agro-environmental planning and environmental management. The goal of this paper is to compare the data base of a Geo-referenced Information System (GIS) and a Decision Support System (DSS), aiming at the planning of the Hydrographic Micro Basin in the Jardim Stream located in the city of Santo Antonio do Jardim - SP. The acquired results in the Capacity Use Class were different in the comparison between classes, but when these same classes were collected as a group, the result was similar. The GIS and the Specialist System classified approximately 40% in Group B, of adequate areas for grazing and reforestation and had different results for Group A, adequate for use with annual and long-term cultures and also having different results for Group C, that should be used for environmental preservation. The Evaluation, regarding soil use, did not show a significant difference, obtaining results of about 45% of the Micro basin area being used in an adequate way and 47% with inadequate use. As a result of the Decision Support System and the Geo-referenced Information System, a conservation plan was made for the micro basin, taking into consideration the sustainability of the environmental resources. / Doutorado / Planejamento e Desenvolvimento Rural Sustentável / Doutor em Engenharia Agrícola
