Effect of population increase on public water and sanitation facilities in densely populated area, Aboabo, Kumasi, Ghana.
Town sheet maps, layout and population census data of Aboabo. GPS for observing spatial locations existing water and sanitation facilities and field verification exercise in the study. GIS for building geodatabase, digitization and Cartographic Visualization. Questionnaires were used to collect non-spatial information on the sanitation facilities and all public facilities.
GIS and a Statistical Approach have been respectively used to develop cartographic and mathematical models to analyse, predict and visualize the effect of population increase on public water and sewage facilities in densely populated area. The developed mathematical models correlates with the population at each instance to the required number of water accessible points or standing pipes as well as the number of required public toilet (sewage) facilities. The cartographic and mathematical models provides an efficient and effective means of mitigating diseases associated with water and sanitation; and informs planners and assembly members of the effects of increasing population on public facilities for proper future planning and geospatial decision making; and to ensure proper infrastructural management at the community levels.
Effective decision support systems for analysing, predicting and visualizing public water and sewage facilities in densely populated area. Draws the awareness of the government, concerned groups and non-Governmental Organizations (NGO's) to the extreme detrimental effect that the increase in population has, especially on public water and sewage facilities and how it can be managed at the community level.
加纳库马西阿博阿博人口密集地区人口增长对公共供水和卫生设施的影响。
阿博阿博的城镇规划图、布局图及人口普查数据。利用全球定位系统（GPS）观测现有供水和卫生设施的空间位置，并在研究中进行实地核查。利用地理信息系统（GIS）建立地理数据库、进行数字化处理和制图可视化。通过问卷调查收集有关卫生设施及所有公共设施的非空间信息。
分别运用GIS和统计方法建立了制图模型和数学模型，以分析、预测和可视化人口增长对人口密集地区公共供水和污水设施的影响。所建立的数学模型将每个时间点的人口与所需的取水点或立管数量以及所需的公共厕所（污水）设施数量关联起来。制图模型和数学模型为减轻与水和卫生相关的疾病提供了一种高效且有效的手段；并让规划者和市政议员了解人口增长对公共设施的影响，以便进行合理的未来规划和地理空间决策；并确保社区层面的基础设施得到妥善管理。
建立了有效的决策支持系统，用于分析、预测和可视化人口密集地区的公共供水和污水设施。提高了政府、相关团体和非政府组织对人口增长所产生的极端有害影响的认识，特别是对公共供水和污水设施的影响，以及如何在社区层面进行管理。
