    Abstract: Andean grasslands ( páramos ) are highly valued for their role in regional water supply as well as for their biodiversity and large soil carbon stocks. Several Payment for Ecosystem Services (PES) programmes promote either afforestation or alteration of traditional burning regimes under the assumption that these land management strategies will maximize páramo ecosystem services, including carbon storage. However, knowledge of the effects of incentivized land uses is limited. In an evaluation of how afforestation and elimination of burning affect carbon storage at a site in southern Ecuador, we found the highest above-ground biomass carbon levels at afforested sites (99.3–122.0 t C ha −1 ), while grassland sites reached 23.9 t C ha −1 after 45 years of burn exclusion. Soil carbon storage from 0–20 cm was high across all sites (172.8–201.9 t C ha −1 ), but was significantly lower with afforestation than with burn exclusion. These findings suggest that, although afforestation is generally favoured when carbon is the primary ecosystem service of interest, grasslands with infrequent burning have important potential as a land management strategy when both above-ground biomass and soil carbon are considered. These results are relevant to the development and adaptation of PES programmes focused on carbon as well as those focused on multiple ecosystem services.

    Abstract: Ecosystem services programmes have been advocated for their potential to join conservation and poverty alleviation efforts, integrate working landscapes, and provide a flow of ecosystem services upon which populations rely. Ecuadorian páramo grasslands have rapidly become the focus of compensation for ecosystem services (CES) programmes intended to conserve hydrologic services, carbon sequestration and biodiversity. This paper reviews CES programmes in Ecuadorian páramos using a combination of semi-structured interviews with project personnel, policy makers and community leaders involved in CES programme development, document analysis, and archival research. Findings indicate that, in some cases, CES schemes can support local development, with potential to contribute to poverty alleviation; however, measures of programme effects on poverty were lacking. The programmes fell across the spectrum of activity-reducing to activity-enhancing, with some functioning as protected areas and others integrating working landscapes; however, designation of land as protected did not necessarily imply more restrictive use. Finally, these cases all reflect scenarios in which limited information is available linking land use with ecosystem services production and underscore the idea that adequate understanding of ecosystem production functions continues to be a barrier to development of effective programmes, particularly where the provision of multiple ecosystem services is anticipated.
