Specific lessons learned in this review highlight the following suggestions:

There are good pieces available for many of the adaptation processes and the most urgent challenges ahead. 
Gaps in the coverage of adaptation pathways are significant, especially for long-term investment decisions. Cross-sectoral areas that may be worth more focused guidance include: Biofuels and competition for food crops; Water and energy and landscape planning; Land ownership and foreign investment; Private sector business models and value chains that reach the many small-scale producers and food processors.
Guidance on specific processes (learning platforms on risks and opportunities) would support practical decision making.
Online knowledge management services should be integrated into guidance and decision processes. For instance, an online service could screen project proposals against agreed criteria.
Templates for national guides would build a working library of good practice. A library of good practice examples would complement the more generic guidance. A set of templates could be created that are relatively easy to adapt to specific countries and agricultural systems.
