Statistics for rainforest cover and deforestation during the 1980s comes from State of the World's Forests 1999 (SOFO) published by the United Nations Food and Agriculture Organization (FAO) and Myers, N.

Agriculture
The background for agriculture in the tropical rainforest draws heavily from T. Nishizawa and J. I. Uitto, eds. (The Fragile Tropics of Latin America: Sustainable Management of Changing Environments, New York: United Nations University Press, 1995) and Smith, N.J.H. et al., Amazonia - Resiliency and Dynamism of the Land and its People, New York: United Nations University Press, 1995. The study which suggests nearly 12% of terre firme forests in the Amazon are anthropogenic is found in Balée, W., "The culture of Amazonian forests," Advances in Economic Botany 7: 1-21, 1989.
Myers, N. estimated in "Nature's Greatest Heritage Under Threat," Rainforests-The Illustrated Library of the Earth, Norman Myers, ed., Emmaus, Pennsylvania: Rodale Press, 1993 that roughly 60% of deforestation is caused by the shifted cultivator.
Skewed land distribution is discussed in Wood, C.H. and M. Schmink, "Blaming the victim: Small farmer production in an Amazon colonization project," Studies in Third World Societies 7: 77-93, 1978; Myers, N. "Nature's Greatest Heritage Under Threat," Rainforests-The Illustrated Library of the Earth, Norman Myers, ed., Emmaus, Pennsylvania: Rodale Press, 1993; and Smith, N.J.H. et al., Amazonia - Resiliency and Dynamism of the Land and its People, New York: United Nations University Press, 1995.

Greenberg, R. et al., "Bird Populations in Shade and Sun Coffee Plantations in Central Guatemala," Conservation Biology Vol. 11 No. 24 (48-59), Apr. 1997, demonstrate higher biodiversity under agroforestry systems (shade coffee plantations) than conventional coffee plantations.

The failure of many Indonesian transmigrant agriculture programs as a result of a lack of planning and administration is discussed in Brookfield, H., Potter, L., and Byron, Y., In Place of the Forest: Environmental and Socio-economic Transformation in Borneo and the Eastern Malay Peninsula (New York: United Nations University Press, 1995),
Myers, N. ("The world's forests: problems and potentials." Environmental Conservation 23 (2) p. 158-168. 1996) estimates the population of subsistence farmers dependent on tropical forests at more than 600 million and projects their growth rate at 4-6% per year.
The Harvest of Sustainable Forest Products
The list of non-wood forest products is taken from State of the World's Forests 1999 (SOFO) published by the United Nations Food and Agriculture Organization (FAO).
Examples of sustainable harvest values come from studies in Peru (Peters, C.M., Gentry, A.H., and Mendelsohn, R.O., "Valuation of an Amazonian Rainforest," Nature Vol. 339: 655-656 1989) and Ecuador (Grimes, A. et al., "Valuing the rain forest: the economic value of nontimber forest products in Ecuador," Ambio Vol. 23 No. 7, Nov. 1994).
The Rainforest Action Network (1995) estimates U.S. imports of tropical American nuts at more than $300 million per year.

The Rainforest Action Network (1996) is assisting in a project to develop the sustainable collection of rattan-like vines in Brazil by the rural poor.
The practice is extracting venom by snakes on farms in the Congo is reported by T'sas, V., "Snake Venom, Congo's next Export?" Reuters 10/20/97.
The "brief history of rubber" box is excerpted from Wade Davis' One River (New York: Touchstone, 1996). Davis provides a broad and insightful look into the rubber business.
The overharvesting of the Wotango tree is discussed in Strieker, Gary, "Mission impossible: conserving Cameroon's natural resources," CNN Online, February 25, 1997.
Caufield, C., (In the Rainforest, Chicago: University of Chicago Press, 1984) lists foods with origins in the rainforest, while Wilson, E.O., (The Diversity of Life, Cambridge, Mass.: Belknap Press, 1992) notes that only a fraction of the world's edible plants are consumed. He suggests that rainforests could be the source of new fruits, vegetables, and nuts that are better suited to tropical agriculture. Wilson notes that currently only about 200 rainforest fruits are regularly used.
Wilson (The Diversity of Life, Cambridge, Mass.: Belknap Press, 1992) goes on to point out that almost no tropical animals are exploited on a commercial basis (i.e. raised in farms). He cites several species with potential including the Amazon river turtle (Podocnemis sp). Smith, N.J.H. ("Destructive exploitation of the South American river turtle," Yearbook of the Pacific Coast Geographers 36: 85-102, 1974; and "Aquatic turtles of Amazônia An endangered resource," Biological Conservation 16(3): 165-176, 1979) and Mittermeier, R.A., ("South American River Turtles: Saving Their Future," Oryx, 14 (3): 222-230, 1978) have conducted studies on the viability of Podocnemis farming on Amazonian floodplains and has reached some promising conclusions.
Jared Diamond (Guns, Germs, and Steel (New York: W.W. Norton & Company, 1998) suggests that the reason these tropical species have never been domesticated is they are poor candidates for domestication, though he does not discount the idea that they could be utilized in some manner.
N. Myers ("Population and Biodiversity," Ambio Vol 24 No. 1, Feb. 1995) and E.O. Wilson (The Diversity of Life, Cambridge, Mass.: Belknap Press, 1992) discuss the declining diversity of major food crops and the associated dangers of reduced genetic stock. Wilson recalls the near miss with Asian rice and grassy stunt virus in the 1970s, while Tarnowski, A. ("Scientists to Tap Amazon for Disease-Free Cocoa Strains," Reuters, 12/10/97) notes how vulnerable the Ghanan cocoa crop is given its narrow genetic base. Holdgate, M. ("The Ecological Significance of Biological Diversity," Ambio Vol. 25 No. 6, Sept. 1996) runs down the savings from genetic resources. Also see Robinson, J.G. and Reford, K.H., eds. (The Value of Conserving Genetic Resources; Neotropical Wildlife Use and Conservation, Chicago: University of Chicago Press, 1991).
The importance of forests in maintaining food security is reviewed in Pimentel, D., McNair, M., Buck, I., Pimentel, M., and Kamil, J., "The value of forests to world food security," Human Ecology, 1996.

Recent news
Amazon deforestation rate falls to lowest on record
(8/10/2007) Deforestation rates in the Brazilian Amazon for the previous year were the lowest on record, according to preliminary figures released by INPE, Brazil's National Institute of Space Research.
Lowland rainforest less diverse than previously thought
(8/9/2007) While rainforests are the world's libraries of biodiversity, species richness may be more evenly distributed in some forests than in others, reports an extensive new study by an international team of entomologists and botanists. The work, published in the current issue of the journal Nature, has important implications for forest management and conservation strategies.
Experts: parks effectively protect rainforest in Peru
(8/9/2007) High-resolution satellite monitoring of the Amazon rainforest in Peru shows that land-use and conservation policies have had a measurable impact on deforestation rates. The research is published in the August 9, 2007, on-line edition of Science Express.
