Dan Lunt, Andy Ridgwell and I have got a paper in press at JGR-
atmospheres that might be of interest on urban, crop and desert
geoengineering:

It would be very interesting to see this work combined with an assessment
of a concurrent, robust strategy to minimise BC emissions in the Indian sub
continent and S Asia region more generally.
If BC could be addressed in this way, it may be possible to reduce the net
impact of SRM geoengineering

Drainage management looks like a technique worthy of further study. There
are numerous issues at stake. Methane excursions may be modest, and the
climate effect, particularly in the long term, may instead be exacerbated
by the effect of the additional carbon released as co2 by drainage.
Looking strictly at the geoengineering section in Appendix B, I find
the analysis pretty thin and a little sloppy (Solar Radiation
Management techniques ... seek to increase the amount of the solar
radiation reflected back into space thus increasing the Earth's albedo
