Rainforests are the most biologically diverse terrestrial ecosystem on Earth and provide a wide range of critical ecosystem services from regulating water cycles to recycling nutrients, to the storage of carbon. According to research by Dr. Claude Martin:
The area covered by tropical rainforests at that time {Humboldt and Bonplandâs expedition in 1799â1804} was still close to the 1.6 billion hectares believed to be the original maximum distribution areas {âŠ}. Today less than half this area remains as undisturbed forest {less than 800 million hectares}ânobody knows exactly how muchâand about another quarter survives as fragmented and degraded forest.1
This said, significant financial resources from both the private and public sectors need to be mobilized to reverse this trend of tropical rainforest deforestation, while at the same time to restore degraded areas. As of January 2016, it is estimated that approximately â$52 billion per year flows to conservation projects {i.e., not just rainforest conservation}, the bulk of it is public and philanthropic funds.â
2 In addition, approximately USD$8.2 billion was invested by the private sector from 2004 to 2015 in the following âthree groups of conservation-oriented investments:
Sustainable food and fiber production (e.g., forestry, agriculture, and fisheries);
Habitat conservation (e.g., mitigation banking and forest carbon trading); and
Water quality and quantity protection (e.g., watershed protection and water rights trading).â3
However, going forward, â{âŠ} to finance the preservation of the worldâs precious ecosystems {including tropical rainforests} will require $200 billion to $300 billion in additional capital, and private investment capital may be the main source of additional capital. Attracting such a level of private capital will require attractive risk-adjusted rates of return, in addition to clear and measurable conservation impacts.â4 As stated by the former Commission on Climate and Tropical Forests, approximately USD$30 billion a year âwill be required to reduce emissions from tropical deforestation by half in 2020.â5
The history of conservation finance arguably dates back to 1634, when the Boston Commons was established and likewise, it is considered âthe oldest public open space in the United States. Indeed, it is very likely the oldest public open space in the English-speaking world.â6 The Bogd Khan Uul National Park in Mongolia was established âby the Mongolian government in 1778, {however} it was originally chartered by Ming Dynasty officials in the 1500s as an area to be kept off limits to extractive uses, protected for its beauty and sacred nature.â7
The first documented protected area, according to the World Database on Protected Areas, appears to be a nature park in Russia known as the Donskoj rybny zapovednik (Donskoe zapretnoe rybnoe prostranstvo) which was established in 1819.8
The first state park appears to be Yosemite National Park in California, United States, which was first designated a state park in 1864,9 while the first national parkâaside from Bogd Khan Uul National Parkâappears to be Yellowstone National Park in the current US states of Wyoming, Montana, and Idaho in 1872.10
In 1891, the Trustees of Public Reservations (now the Trustees of Reservations, or TTOR) became the worldâs first regional land trust,11 which established the worldâs first conservation easement in Boston, Massachusetts.12
It is difficult to discern when the first government international budgetary expenditures for conservation were allocated. However, it is likely this mechanism was first established in the late nineteenth century or early twentieth century, when the worldâs first international conservation organizations were established. This includes the Society for the Preservation of the Wild Fauna of the Empire (now known as Fauna and Flora International or FFI), which was founded in 1903,13 and the International Council for Bird Preservation (ICBP; the ICBP would rebrand as BirdLife International in 1993) was established in 1922.14 Similarly, Waterton Glacier International Peace Park was established in 1932 between the United States of America and Canada and marked the worldâs first international peace park.15
Modern-day impact investing is comparable to socially responsible investing, which took â{âŠ} off in the 1970s as part of grassroots campaigns to boycott firms in South Africa {as a result of Apartheid} as well as the nuclear weapons and tobacco industries.â16
In the late 1970s, the concept of payments for ecosystem services (PES, referred to earlier as payments for environmental services) begins to appear.17
Low-impact tourism likely began earlier, but in 1983, the term âecotourismâ is first coined by Mexican architect HĂ©ctor Ceballos-LascurĂĄin.18
Debt-for-nature swaps came along shortly thereafter with the first such debt-for-nature swaps conducted in 1987 in both Bolivia and Ecuador .19
Then in 1991, the worldâs first major bioprospecting deal was struck between Merck & Co. and Costa Ricaâs Instituto Nacional de Biodiversidad (INBio).20
The sustainable, green procurement of locally produced commoditiesâparticularly by Indigenous Peoples and forest-dependent communitiesâhas existed for thousands of years. However, the origin of commercial, green procurement with independent certification standards likely started with the creation of the Forest Stewardship Council (FSC)21 and the Sustainable Forestry Initiative (SFI) in 1994.22
The first widely recognized green bonds were issued in 2007 and 2008 by the World Bank23 and European Investment Bank.24
With this historical overview in mind, it appears as though the two most promising conservation financing instruments are the payments for ecosystem ...
