AbstractSPICA is one of the key projects for the future. Not only its instrument suite will open up a discovery window but they will also allow to physically understand some of the phenomena that we still do not understand in the high-redshift universe. Using new homogeneous luminosity functions (LFs) in the Far-Ultraviolet (FUV) from VVDS and in the Far-Infrared (FIR) from Herschel/PEP and Herschel/HerMES, we studied the evolution of the dust attenuation with redshift. With this information, we are able to estimate the redshift evolution of the total (FUV + FIR) star formation rate density (SFRDTOT). Our main conclusions are that: 1) the dust attenuation AFUV is found to increase from z = 0 to z approximately 1.2 and then starts to decrease until our last data point at z = 3.6; 2) the estimated SFRD confirms published results to z approximately 2. At z greater than 2, we observe either a plateau or a small increase up to z approximately 3 and then a likely decrease up to z = 3.6; 3) the peak of AFUV is delayed with respect to the plateau of SFRDTOT but the origin of this delay is not understood yet, and SPICA instruments will provide clues to move further in the physical understanding of this delay but also on the detection and redshift measurements of galaxies at higher redshifts. This work is further detailed in Burgarella et al. (2013).
