If they want to improve their performance in the SENA nations, then having green pitches is definitely one of the top priorities. Along with that, there should be a few other steps. About two decades back, the India A and India U-23 teams used to tour countries such as Australia and England regularly. The tours still happen, but they have become very infrequent. Another aspect where I want the BCCI to focus is on the MRF Pace Foundation. Until Dennis Lillee was there (till 2012), it was producing a huge number of quality pace bowlers. But now, the quality seems to have gone down. On paper, Glenn McGrath is the Director. But he has other priorities.
As far as i know India A do visit in SENA regularly. I remember England-New Zealand tour of India A, not sure about U-23 though. Guess its not big news so we don't get to read much about it via print media.
I didn't follow MRF Pace Foundation updates for quite some time now, so no comment.
