 s can be found in a wide variety of Earth and Planetary Systems. Solving f
 or mass\, momentum and energy conservation becomes difficult because they 
 are regulated by dynamic interfaces between the different components. Here
 \, we will discuss the merits of continuum (spatially averaged) and discre
 te scale (granular where interfaces are explicitly treated) approaches in 
 the light of different applications ranging from Planetary Sciences (water
  on Mars)\, to volcanology (bubble dynamics and rheology) and finally hydr
 ology (heat transfer in porous media). The goal of the presentation is to 
 discuss the necessity to develop a framework consistent with the granular 
 scale (downscaling) as well as different elements of approaches for upscal
 ing (effective medium theory\, fractional derivatives).</span></span>
