This paper examines the potential mutual conflict between interventions aimed at formalising artisanal and small-scale mining (ASM) on the one hand, and policies implemented in response to the Reducing Emissions from Deforestation and Forest Degradation (REDD) initiative on the other. Deforestation caused by ASM undermines sound forest management, and potentially threatens the implementation of REDD. Conversely, the adoption of REDD could further marginalise and criminalise the ASM sector, reducing its contribution to poverty alleviation. Reviewing a series of commonalities between ASM and forest management highlights many difficulties facing policy-makers. Potentially, contradictory outcomes of evolving governance arrangements means novel cross-sectoral institutions will be required in order to realise the full potential of REDD and ASM to address poverty reduction in a complementary fashion. The analysis reiterates the centrality of livelihoods to REDD and the need for policies to take into account local contexts.

ASM 981 has been developed for topical treatment of inflammatory skin diseases. It specifically inhibits the production and release of pro-inflammatory cytokines. We measured the skin penetration of ASM 981 in canine skin and compared penetration in living and frozen skin. To make penetration of ASM 981 visible in dog skin, tritium labelled ASM 981 was applied to a living dog and to defrosted skin of the same dog. Using qualitative autoradiography the radioactive molecules were detected in the lumen of the hair follicles until the infundibulum, around the superficial parts of the hair follicles and into a depth of the dermis of 200 to 500 microm. Activity could not be found in deeper parts of the hair follicles, the dermis or in the sebaceous glands. Penetration of ASM 981 is low in canine skin and is only equally spread in the upper third of the dermis 24 hours after application. Penetration in frozen skin takes even longer than in living canine skin but shows the same distribution.
