Putnam's article and then book entitled Bowling Alone traced the decline of social capital during the past several decades and the effects of this decline. The Saguaro Seminar brought together a diverse group of individuals to think about what could be done to counteract this trend.
(Disclosure: I worked for Bob Putnam for several years and I was rapporteur to the Saguaro Seminar.)
Among the proposals of the Saguaro Seminar is for government, when it considers new policies, to conduct a Social Capital Impact Assessment. In essence, policymakers, in considering the benefits and downsides of any program, would be required to take account of the social capital impact. Ideally, government would then adopt an approach that helped to preserve or generate social capital. (To give a simple example: in choosing between two possible locations for a shopping mall, government would select the location that did not displace or disrupt an existing community.)
Over the years, Presidents have required executive personnel to measure and take account of the impact of regulatory choices on designated variables. President Reagan, for example, issued an Executive Order requiring executive personnel to examine the impact of federal programs on federalism and, where possible, to minimize the erosion of state authority. Congress can also require impact statements: one obvious example is Section 102 of the 1970 National Environmental Protection Act which required federal officials to prepare and distribute a detailed impact environmental impact statement for any federal policy or project significantly affecting the quality of the environment.
With a member of the Saguaro Seminar now in the White House, and there in large measure as a result of increased civic engagement, there is a reasonable chance that federal agencies will be required in the near future to take account of the impact of regulatory programs on levels of social capital.
