Payments for Hydrologic Services (PHS) programs are increasingly used as a policy tool to provide incentives for upstream landowners to adopt land use activities that favor sustainable provision of high-quality water to downstream areas. However, the effectiveness of PHS programs in achieving their objectives and the potential for unintended (often undesirable) consequences remain poorly understood. We integrate results from ecohydrological and socioeconomic research to explore the impact of Mexico’s PHS program on the target hydrologic services and people’s decisions, behavior, and knowledge regarding forest conservation and water. Using central Veracruz as our case study, we identify areas of both synchrony and disconnection between PHS goals and outcomes. Mature and regenerating cloud forests (targeted by PHS) were found to produce enhanced hydrologic services relative to areas converted to pasture, including reduced peak flows during large rain events and maintenance of dry-season base flows. However, unexpectedly, these hydrologic benefits from cloud forests were not necessarily greater than those from other vegetation types. Consequently, the location of forests in strategic watershed positions (e.g., where deforestation risk or hydrologic recharge are high) may be more critical than forest type in promoting hydrologic functions within watersheds and should be considered when targeting PHS payments. While our results suggest that participation in PHS improved the level of knowledge among watershed inhabitants about forest–water relationships, a mismatch existed between payment amounts and landowner opportunity costs, which may contribute to the modest success in targeting priority areas within watersheds.

Combined, these findings underscore the complexity of factors that influence motivations for PHS participation and land use decisions and behavior, and the importance of integrating understanding of both ecohydrological and socioeconomic dynamics into PHS design and implementation. We conclude by identifying opportunities for improving the design of PHS programs and recommending priority areas for future research and monitoring, both in Mexico and globally.

Land system science axiomatically addresses social–environmental systems by integrating the dynamics of land uses (social) and land covers (environment), invariably including the use of remote sensing data and often, spatially explicit models of land change. This kind of research is illustrated through the Southern Yucatán Peninsular Region project (1997–2008) aimed at understanding, predicting, and projecting spatially explicit land change in a region with juxtaposed land uses-agriculture and a biosphere reserve. The successes of the project, its contributions to contemporary land system science, and the organizational mechanisms that fostered the research are identified as well as various corrections, which if applied, may have refined and extended the project's goals. Overall, the project demonstrates the kind of integrated research required to advance understanding of a social-environment system and the team-based methods used in the process.

Resumen en inglés

Research addressed a range of issues relating to the regional determinants of species diversity, the effects of fragmentation and human disturbance on tree diversity at different spatial scales, changes of diversity along secondary succession after deforestation, and plausible future scenarios of species decline associated with continued habitat loss across a variety of ecological and socio-economic conditions in Latin America. This analysis was performed using different woody vegetation datasets in combination with various field measurements, remote sensing and GIS data. Regionally, climatic factors emerged as primary predictors of tree diversity. At finer scales, fragmentation and human disturbance better explained patterns of species diversity. These effects were, however, dependent on the time after fragmentation occurred. In the short term, habitat fragmentation was not likely to reduce the overall diversity of a fragment, but could have a slight positive effect on local diversity within fragments. Moreover, we detected a negative effect of human disturbance that far outweighed the effects of fragmentation at this scale. In the long term, however, fragmentation was found to significantly reduce the overall diversity of forest remnants.

Patterns of diversity along chronosequences of abandoned pastures and croplands were consistent across all study areas in Mexico and suggested that vegetation structure and community composition gradually come to mirror those of mature forests. However, species richness strongly depended upon the functional type under consideration. Using ground-based floristic inventories and forest loss rates derived from satellite imagery, we estimated the percentage of species most likely to disappear, or at least become ser iously threatened with extirpation, assuming continued habitat loss until 2025. Alarmingly, the predicted species decline in the Highlands of Chiapas was over 40% using estimated yearly deforestation rates of 4.8%.
