This might be termed the 'bioregionalist or social development' approach. An example is participatory community and resource planning. This approach is often neglected due to political and institutional needs for responses that appear to have quicker consequences. Dynamics of Complex Systems There are a couple other important systemic features of complex systems relating to sustainable development. A second feature of managing complex systems is the role of positive and negative feedback.
Positive feedback leads to amplifying a change made in the system.
An example would be if the release of greenhouse gases by human action leads to a warming of permafrost that in turn causes more greenhouse gases to be released and thus further increases global warming. Negative feedback counteracts the force of a given action back towards original conditions. An example would be if increased greenhouse gases in the atmosphere lead to the increased creation of greenhouse gas-sequestering plankton in the oceans and vegetation on the land. Challenging Characteristics of Managing Complex Systems Planet management and social development approaches form a continuum of planning and management responses to SD issues. SD issues exhibit various degrees of several important ecological characteristics.
