Collaborative management of hydrological ecosystem services: a multilevel social network analysis of a Mexican watershed.

Collaborative management of hydrological ecosystem services (HES) is crucial for their conservation and involves diverse stakeholders at three levels: environmental and land-use management (ELM), harvesting and physical access (HPA), and appropriation and appreciation (AA). This study analyzes collaborative networks within and between these levels in the Copalita-Huatulco watershed, Mexico, using a monoplex and multiplex social network approach to understand stakeholder interactions. Results indicate that the ELM and AA networks are diverse and polycentric, with NGOs occupying an influential role.

Analysis of the watershed social-ecological system trajectory in Copalita-Huatulco, Mexico: The impact of drivers on hydrological ecosystem services.

In watersheds, which function as social-ecological systems (SESs), hydrological ecosystem services (HESs) are crucial flows connecting natural and social components. The internal and external drivers that shape HESs and watershed SES trajectories create complexities in watershed management. In this study, the adaptive cycle framework was adopted, and a qualitative method is proposed to analyze the impacts of drivers on the HES and the watershed SES trajectory.

Estimating shadow prices in economies with multiple market failures.

Approaches to the estimation of shadow prices generally assume that all but one market function correctly. However, multiple market failures are common in developing countries. We present a theoretical model and an empirical strategy to estimate the shadow price of a subsistence good in an economy where labor markets fail.

The historical trajectory of a coffee agri-food system: A case study in Oaxaca, Mexico.

Agri-food social-ecological systems (AFSES) embrace complex interactions and processes of food production, processing, and commercialization that are subject to constant changes. This study develops a heuristic approach using the adaptive cycle (AC) and a transformation potential measure to identify the historical trajectory of a coffee AFSES at a watershed scale in Copalita, Mexico, over 40 years from 1980 to 2020. Primary information was collected through semistructured interviews.
