What is GeoDesign and what is the relationship with Disaster Risk Assessment (or any other GISc related project)? This short narrative will discuss this.
In short: GeoDesign can be broken into two syllables, Geo and Design. Geo represents the geographic space or space that is referenced to the surface of the earth (geo-referenced). Design is the thought process comprising the creation of something and therefore GeoDesign is a thought process comprising the creation of entities in space.
To implement GeoDesign practically a process needs to be followed. This process is very similar to a scientific research project and is shown in the figure below.
The process starts, as usual, with a problem for which a solution must be fined. To do this the problem must first be described after it can be analysed. To visualise the problem is part of the analysing the problem. This is where “geo” comes in by visualising the problem using GISc techniques and software. Through various processes and techniques ( research and/designed led innovation or brainstormings) solution can be identified and again GIS can be used to visualise the solution.
The solution/ prototype must be tested and if successful, implemented in the real world.
Disaster Risk Assessment
Disaster risk assessment follows the same process. A next blog will describe the practical implementation of GeoDesign and disaster risk assessment through conducting a GISc project during which a specific project plan will be discussed.
The problem can be to identify possible water pollution areas. Through study and research, the problem is described and analysed. GISc techniques can be used to visualise the possible areas and through this visualisation possible water pollution areas can be confirmed and presented in map format. Through ground truthing, the assessment can be tested and incorporated into a disaster risk profile and disaster risk reduction strategy and programs.
