Payment for environmental services (PES) programmes have often overlooked intra-community differences, which affect the understanding of implementation requirements and access to benefits, thus underestimating their effects on the programme's legitimacy and impacts. We explore how the views of local communities about the socio-environmental performance and dynamics of Mexico's PES differ within forest communities, considering two groups: local community authorities and the remaining beneficiaries in two different PES programmes. Informed by a nationwide survey, we constructed 35 indicators and found significant differences between these groups for 10 indicators. Local community authorities concentrated knowledge and information, relations with outside actors and control over benefit distribution. We found that community authoritie...

The data from this interval indicate a period of climatic instability that lasted until 8500 cal yr B.P., when temperature conditions stabilized, although moisture fluctuations continued until 8000 cal yr B.P. Between 8500 and 5000 cal yr B.P. a temperate climate is indicated by dominance of Pinus. From 5000 to 3000 cal yr B.P. Quercus forest expanded, suggesting a warm temperate climate: a first indication of drier environmental conditions is an increase in grassland between 4200 and 3500 cal yr B.P. During the Late Holocene (3300 to 500 cal yr B.P.) the increase of Pinus and grassland indicates temperate dry conditions, with a considerable increase of Pinus between 1100 and 950 cal yr B.P. At the end of this period, humidity increased. The main tendency during the Holocene was a change from humid to dry conditions. During the Early Holocene, Almoloya L...

En outre, puisque l'on admet l'âge maastrichtien inferieur de la Formation Olmos, l'extinction biostratigraphique du groupe apparait regionalement plus precoce que dans la plaine cotiere atlantique.

Metodología: análisis cualitativo basado en la tipología de coherencia de políticas públicas para el desarrollo. Resultados: los beneficiarios de los programas dependen económicamente de los subsidios otorgados, existen restricciones para el desarrollo de actividades productivas, los mecanismos financieros son ineficientes y falta una visión de sostenibilidad que considere las dimensiones socioeconómicas. Limitaciones: escasa participación de las autoridades y comuneros en este tipo de estudios y falta de información sobre las interrelaciones de instituciones y programas de trabajo. Valor: analizar las políticas públicas periurbanas mediante la coherencia de políticas públicas para el desarrollo. Conclusiones: aplicar el marco teórico-metodológico de la cohere...

Few initiatives have mechanisms that let them monitor the results obtained. This article shows the methodological procedure used to develop the indicators system to follow the Magdalena river recovery in Mexico City. The work has the characteristics to favor multidisciplinary dialogue and the use of constructivist and relational precepts as core ideas to integrate the system. Using selection criteria, the initial indicators list was reduced until a system of 11 strategic indicators was obtained. It is important to remark the centrality of those related to the water quality, citizen participation and governmental coordination. The procedure can be useful to monitor the recovery of other urban rivers in the coun try.
