An assessment of Public Participation GIS and Web 2.0 technologies in urban planning practice in Canela, Brazil

Site-specific agriculture has been adopted in a high-tech context using, for instance, in situ sensors, satellite images for remote sensing analysis, and some other technological devices. However, farmers and smallholders without the economic resources and required knowledge to use and to access the latest technology seem to find an impediment to precision agricultural practices. This article discusses the possibility of adopting precision agriculture (PA) principles for site-specific management but in a low technology context for such farmers. The proposed methodology to support PA combines low technology dependency and a participatory approach by involving smallholders, farmers and experts. The case studies demonstrate how the interplay of low technology and a participative approach may be suitable for smallholders for site-specific agriculture analysis.

“…The 2010 Haiti earthquake has highlighted the role that the Internet can have in a participatory environment [6], in which people not only consume content, but also produce new content [28]. The idea of "citizens as sensors" [8] underscores the potential that citizens have to be active information producers who can provide timely and cost-effective information (i.e., VGI) in support of disaster management activities [8,29].…”

Recent disasters, such as the 2010 Haiti earthquake, have drawn attention to the potential role of citizens as active information producers. By using location-aware devices such as smartphones to collect geographic information in the form of geo-tagged text, photos, or videos, and sharing this information through online social media, such as Twitter, citizens create Volunteered Geographic Information (VGI). To effectively use this information for disaster management, we developed a VGI framework for the discovery of VGI. This framework consists of four components: (i) a VGI brokering module to provide a standard service interface to retrieve VGI from multiple resources based on spatial, temporal, and semantic parameters; (ii) a VGI quality control component, which employs semantic filtering and cross-referencing techniques to evaluate VGI; (iii) a VGI publisher module, which uses a service-based delivery mechanism to disseminate VGI, and (iv) a VGI discovery component to locate, browse, and query metadata about available VGI datasets. In a case study we employed a FOSS (Free and Open Source Software) strategy, open standards/specifications, and free/open data to show the utility of the framework. We demonstrate that the framework can facilitate data discovery for disaster management. The addition of quality metrics and a single aggregated source of relevant crisis VGI will allow OPEN ACCESS ISPRS Int. J. Geo-Inf. 2015, 4 1390 users to make informed policy choices that could save lives, meet basic humanitarian needs earlier, and perhaps limit environmental and economic damage.

“…In the early stages of development, scholars focused more effort on evaluating PPGIS/PGIS tools and technology than participatory outcomes or the quality of the spatial data. For example, multiple studies have assessed the usability of PPGIS/PGIS (Aditya, 2010;Bugs, 2010;Jankowski & Nyerges, 2003;Sidlar & Rinner, 2009;Steinmann et al, 2004), but relatively few studies have examined the effects on empowerment (Corbett & Keller, 2004;Kyem, 2001;Tsai et al, 2013) or engagement (Rinner & Bird, 2009). There is also a small, but expanding…”

Public participation for land use planning in developing countries is challenged by multiple barriers including low public awareness and engagement with the process. This paper evaluates the capacity of the general public to effectively contribute to land use planning outcomes in Malaysia using Participatory GIS (PGIS). Spatial attributes that identify place values and land use preferences were collected from the public through a web-based PGIS using facilitated and self-administered methods and compared with land use zones developed by planning experts. We assessed the quality of the PGIS mapped data by analysing participants' mapping effort and the consistency of the mapped data with existing land use zones. The results indicate logical consistency between the mapped attributes-place values and preferences-and land use zones contained in the expert-driven land use plans. The results further indicate that the facilitated PGIS process produced higher quality spatial data compared with the self-administered PGIS survey. Our results suggest that PGIS can provide planning authorities with a viable platform to enhance public participation for land use planning in Malaysia, but that a facilitated PGIS process will be required to increase public participation and the quality of spatial data generated.
