This presentation explores the challenges of understanding reconnection in complex
astrophysical environments, emphasizing its multiscale nature, the coupling of large-scale MHD
dynamics with kinetic dissipation processes, and the unique features of 3D reconnection. The role
of turbulence, both as a driver and a product of reconnection, is discussed, highlighting how it
accelerates the reconnection rate and impacts energy distribution. Investigations of instability-driven
turbulence, including tearing mode and Kelvin-Helmholtz instability, offer insights into the
mechanisms that sustain turbulent energy cascades. The implications of fast reconnection for particle
acceleration in relativistic magnetized jets are also examined, showcasing its significance in highenergy
astrophysical phenomena such as cosmic ray production. These findings underscore the
importance of reconnection in the broader context of astrophysical plasma dynamics and energy
release mechanisms.
