I'm sure there are many ways to do it. One would be to watch the MD5 of the file, and send a mail when it changes.

Code:
ORIGMD5=`crontab -l | md5sum`

while ( true )
do
   NEWMD5=`crontab -l | md5sum`
   if [[ "$ORIGMD5" != "$NEWMD5" ]]
   then
      echo "crontab changed" | mail you@example.com
      ORIGMD5=$NEWMD5
   fi
   sleep 60
done
