It is estimated that the percentage of Costa Rican land covered by forests has gone up from around 20% in the 1980s to over 50% of the total area in 2013 - a growth of 250%. The program has also reduced the national carbon emissions by 11 million tons over a period of 6 years from 1999 to 2005. Indigenous communities and women in particular, have benefited due to this program. Buoyed by this success, the World Bank extended its support to the Costa Rican government's initiative by funding a new program titled "Mainstreaming Market-Based Instruments for Environmental Management". Over the years, many international agencies have pushed the national government to make the process of obtaining the payments easier so as to include more underdeveloped communities and cast a wider net for the program.
