Do Costa Rica's payments for environmental services work?
September 17, 2007
In the 1990s Costa Rica set a new course; one that sought to unlock the value of its ecosystems. While ecotourism was the most obvious path, Costa Rica also pioneered the development of payments for environmental services ("PSA" or pagos por servicios ambientales). In 1996 the country established a program to compensate landowners for keeping forests intact and reforesting degraded areas. A new study, published in Conservation Biology, examines these efforts and concludes concludes that while the program pioneered the institutionalization of a policy that can and likely will create meaningful incentives, to this point in Costa Rica, given other policies, it appears to have had little impact on deforestation.

Some details from the paper:
Payments under the PSA program:
- conservation: $210/ha ($519/acre) in equal installments over 5 years
- reforestation: $537/ha ($1326/acre), with 50% paid the first year, 20% the second year, and 10% over the following 3 years
- forest management: $327/ha in equal installments over 5 years.
- PSA contacts create a legal easement that remains with the property if it is sold (i.e. transferable)
- Landowners transfer carbon offset rights to the national government, which can then sell these offsets on any international market. The landowner does not sell carbon credits directly, instead receiving payment from the government.
- Individuals were restricted to registering 2-300 hectares of land per year. Indigenous groups could register up to 600 ha/year while coalitions acting through local nongovernmental organizations had no limits.
The primary funding for the original PSA program was supposed to come from a 15% consumer tax on fossil fuels, of which the program would collect a third, but the Ministry of Finance rarely delivered that amount. In 2001 a new law was passed, assigning 3.5% of tax revenue directly to the PSA program. The reduced rate "increased actual transfers from the Ministry of Finance" and by 2003 tax revenues provided an average of $6.4 million/year to the program. Funding also comes from voluntary contracts with private hydroelectric producers, who pay for watershed services. Carbon trading "was expected to provide significant funding through sales of certified tradable offsets. However, no significant market for carbon abatement has emerged. The only sale has been to Norway, which
consisted of $2 million in 1997 for 200 million tons of carbon sequestration." Further funding came through a World Bank loan and a Global Environmental Facility (GEF) grant.
Average returns from PSA ranged from US$22 to US$42/ha/year before fencing, tree planting, and certification costs. The main competing land use -- cattle ranching -- shows returns from US$8 to US$125, "depending on location, land type, and ranching practices," according to the authors. "One measure of cattle-ranching returns is the cost of renting 1 ha of pasture. In Cordillera Central, in the heart of Costa Rica, pasture rental ranges from US$20 to US$30/ha/year."
- During the first phase of the PSA program (though 2000) some 300,000 ha of primary, secondary, or planted forest received funding. The mean project size was 102 ha, while the largest project was 4025 ha. The stated land area restrictions were not closely enforced.
- The number of participants entering the program decreased from 1997 to 2000. The authors say this was "probably because funds were not delivered as expected."
- "Payments for conservation alone were larger than the management, but conservation contracts had the lowest payments per unit area. Reforestation and management contracts generally held steady over the years, whereas conservation payments fell (e.g., >$20 million in 1997; almost $12 million in 1999; and <$4 million in 2001).
- Deforestation rates had already dropped significantly by the 1990s, due to other factors (including establishment of protected areas and commodity prices) and it was unclear whether the PSA program had much of an impact on forest clearing: "With or without controlling for these other deforestation-driving variables, the level of PSA contracts in an area never generated significant statistical results concerning a reduction in the country's deforestation rate." The authors add that the PSA program was not explicitly intended to reduce deforestation in Costa Rica and that future programs could specifically target this goal.
Costa Rica's experiment "opens the door" for future PSA programs in other parts of the world, say the researchers.
"We believe Costa Rica's pioneering effort opens the door to further successful PSA programs. The evaluation of its first phase provides important conservation lessons for developing countries interested in similar policies and for new global policies," they conclude.

Environmentalists announce support for carbon trading
(9/14/2007) A coalition of environmental groups announced it will support the development of carbon trading policies that help protect tropical rainforests and other important ecosystems, noting that "conservation alone has proven no match for commerce."
Rainforest countries form pact to push global warming solutions
(9/13/2007) Eight tropical countries containing 80 percent of the world's remaining tropical forest cover have formed an alliance to have forest conservation included in a post-Kyoto agreement on climate change, reports the Financial Times. The "Forestry Eight", as the group is called, includes Brazil, Malaysia, Papua New Guinea, Gabon, Cameroon, Costa Rica, Congo and Indonesia.
Indonesia's peatlands may offer U.S. firms global warming offsets
(8/29/2007) The following is modified version of a letter I've used to pitch U.S. companies on the concept of carbon finance in Indonesia's peatlands. Discussions are slow and the critical December U.N. climate meeting is fast approaching, so I'm posting this as a tool to help you get American firms interested in avoided deforestation offsets. Please feel free to use, modify, and distribute this letter widely.
Avoided deforestation could send $38 billion to third world under global warming pact
(10/31/2006) Avoided deforestation will be a hot point of discussion at next week's climate meeting in Nairobi, Kenya. Already a coalition of 15 rainforest nations have proposed a plan whereby industrialized nations would pay them to protect their forests to offset greenhouse gas emissionsm. Meanwhile, last month Brazil -- which has the world's largest extent of tropical rainforests and the world's highest rate of forest loss -- said it promote a similar initiative at the talks. At stake: potentially billions of dollars for developing countries. When trees are cut greenhouse gases are released into the atmosphere -- roughly 20 percent of annual emissions of such heat-trapping gases result from deforestation and forest degradation. Avoided deforestation is the concept where countries are paid to prevent deforestation that would otherwise occur. Policymakers and environmentalists alike find the idea attractive because it could help fight climate change at a low cost while improving living standards for some of the world's poorest people and preserving biodiversity and other ecosystem services. A number of prominent conservation biologists and development agencies including the World Bank and the U.N. have already endorsed the idea.
