Connectivity at a cost: Economic dynamics of restoring habitat connectivity

Submitted by Vicentia Quartey on
EfD Authors:

Both in the United States and in Europe there is ongoing work on reversing habitat fragmentation and the attendant loss in biodiversity in river systems caused by hydropower and other developments. Fish ladders and other measures are being introduced to restore the connectivity in river systems. In this paper, we set up a theoretical model to investigate what the conditions are for such an investment to be socially profitable.

Implications for Participatory Forest Management and Payments to Communities for Ecosystem Services

  • Communities living near Kenya’s forests place a monetary value on conservation.
  • Mountain forests are the source of rivers that provide water for agriculture and other “ecosystem services” such as flood control and water purification.
  • It is possible for downstream communities that benefit from these ecosystem services to pay the upstream communities to conserve the forests.

Estimating discount rates for environmental goods: Are People’s responses inadequate to frequency of payments?

Submitted by Cristóbal Vásquez on

Most stated preference studies estimate discount rates using a split-sample approach. Each sample faces a different payment frequency (for instance, 1, 5, 10) together with a randomly assigned bid vector; both the frequency of payments and the bid are fixed for a specific individual. This paper evaluates whether allowing respondents to choose their preferred payment frequency affects the estimated discount rate.
