“…[-FAO, 2007, p.97] In the Literature, PES have often been discussed with respect to their potential as a 'just source of reward' for often poor rural dwellers who -in the past -have consciously produced environmental services in care of the environment without any (financial) compensation (see e.g., Bulte et al, 2008;Fisher and Treg, 2007;Gauvin et al, 2010;Greiner and Stanley, 2013, p.6 f.;Noordwijk van et al, 2004;Rosa et al, 2003;Shilling and Osha, 2003). Although PES are generally discussed as a promising potential option to reduce poverty in agricultural, rural settings via direct payments, while concurrently improving environmental management (see e.g., FAO, 2007, p.97;Gauvin et al, 2010, p.499;Swallow et al, 2009, p.3), questions of unintentional adverse side effects have increasingly been raised.…”
