Feasta's particular approach to sustainability economics is to focus attention on the inadequacies of underlying systems. The development of local economies suffers from two particular adverse systemic effects - the in-built transfer of wealth from those that need money to those that already have money via the servicing of debt; and the transfer of wealth from the locality to the centre as globalisation progressively centralises economies. Local currency developers need to develop strategies that mitigate these two effects or they will remain limited in size and influence.
