Site selection to test an integrated approach to agricultural research for development: combining expert knowledge and participatory Geographic Information System methods

Green mussel is one of important species cultured in Lada Bay, Pandeglang. To provide a necessary guidance regarding green mussel mariculture development, finding suitable site is an important step. This study was conducted to identify suitable site for green mussel mariculture development using geographic information system (GIS) based models. Seven important parameters were grouped into two submodels, namely environmental (water temperature, salinity, suspended solid, dissolve oxygen, and bathymetry) and infrastructural (distance to settlement and pond aquaculture). A constraint data was used to exclude the area from suitability maps that cannot be allowed to develop green mussel mariculture, including area of floating net fishing activity and area near electricity station. Analyses of factors and constraints indicated that about 31% of potential area with bottom depth less than 25 m had the most suitable area. This area was shown to have an ideal condition for green mussel mariculture in this study region. This study shows that GIS model is a powerful tool for site selection decision making. The tool can be a valuable tool in solving problems in local, regional, and/or continent areas.

<p>Municipal solid waste (MSM) has been increasingly difficult to deal with, especially for cities of developing countries. In these cities, the increase in waste generation leads to open dumping and the development of landfills without the consideration of environmental assessment and monitoring, which may result in environmental disturbance and risk to human health. Therefore, the main goal of this study was to access the adequacy of the placement of new landfills for Maputo city, Mozambique. The study used the geographic information system (GIS) based on a multi-criteria decision approach that combined environmental, social, and technical variables to aid in the assessment of potential landfill sites. Results indicate that approximately 50% of the area is suitable for landfill placement. A further on-site evaluation is important to validate the obtained results, nonetheless, this preliminary site selection can be integrated into the MSW landfill selection to optimize waste management.</p>

The convergence of public participatory mapping and cybertography is having far-reaching impacts through a variety of creative applications. This paper presents three different types of Internet mapping applications — Google Earth and Google Map API, Common Census, and a design exercise in Second Life — with a public participatory geographic information system (PPGIS) and cybercartography perspective. Each of these examples empowers users in a different way. The spatial applications and the supporting information that is being made available through Internet map applications represent a unique set of examples of the democratization possible through Internet applications.
