information and it uses information about specific landscapes to facilitate broadly-based decision-making
processes that support effective communication and community advocacy (Rambaldi et al. 2006).
The participatory mapping method consists of two major steps: first, topographic maps, aerial photographs
and satellite images are acquired and presented to the community as a ‘blank’ map to facilitate discussion
and the identification of specific features. Second, the data derived through PRA methods are integrated
using GIS and enhanced through additional spatial analysis. Participatory GIS is an emergent practice which
is the result of a spontaneous merger of participatory learning and action (PLA) methods with geographic
information technologies.
GIS has been widely used for the assessment of risk and the management of natural hazards by integrating
it to manipulate information from different sources. It can be used to delineate the different flood risk zones in
such a way that the information acquired can be communicated better and therefore more readily understood
for decision making.
