Payments for environmental services supported social capital while increasing land management

Area of Science:

• Environmental Economics
• Conservation Science
• Social Capital Studies

Background:

• Payments for Environmental Services (PES) programs are increasingly used globally to incentivize natural resource protection.
• A key concern is whether financial incentives erode voluntary conservation efforts and social capital.
• Mexico's federal conservation payments program offers a significant case study for evaluating these impacts.

Purpose of the Study:

• To rigorously assess the causal impacts of Mexico's PES program on land cover management and communal social capital.
• To determine if PES participation leads to a crowding out of unpaid conservation activities or prosocial behavior.
• To provide empirical evidence for the effectiveness of large-scale environmental conditional cash transfer programs.

Main Methods:

• Utilized a regression discontinuity (RD) methodology to establish causal links between program participation and outcomes.
• Compared land management activities and social capital indicators for PES participants and closely matched non-participants.
• Employed quantitative analysis to measure changes in paid and unpaid land management, community social capital, and household trust.

Main Results:

• PES participation led to a significant ~50% increase in land cover management activities.
• No evidence of 'crowding out' was found; paid activities did not diminish unpaid contributions or other prosocial work.
• Community social capital increased by ~8-9%, while household trust remained unaffected.

Conclusions:

• Conditional cash transfer programs like PES can effectively enhance both land management and social capital.
• Financial incentives for conservation do not necessarily undermine voluntary efforts or prosocial behavior.
• Country-specific empirical research is crucial for understanding PES impacts as the programs expand globally.
