Amazon Conservation: How to Save the Amazon Rainforest
By Rhett A. Butler

Between May 2000 and August 2005, Brazil lost more than 132,000 square kilometers of forest—an area larger than Greece—and since 1970, over 600,000 square kilometers (232,000 square miles) of Amazon rainforest have been destroyed. Why is Brazil losing so much forest? What can be done to slow deforestation?
Today Brazil faces an enormous challenge: how to balance economic growth with the preservation of the Amazon rainforest.
In reducing the loss of tropical rainforests we must not only be concerned with the transformation of existing natural ecosystems, but also the more rational utilization of already cleared and degraded areas. To lessen future forest loss we must increase and sustain the productivity of farms, pastures, plantations, and scrub-land in addition to restoring species and ecosystems to degraded habitats. By reducing wasteful land-use practices, consolidating gains on existing cleared lands, and improving already developed lands we can diminish the need to clear additional rainforest.
INCREASING PRODUCTIVITY: [more]
When it comes to cattle pasture, Judson Valentim of the Brazilian Farm Research Corporation (Embrapa), suggests that "the use of so-called alternative technologies, such as non-plowing farming, could increase productivity in areas that have already been cleared ... Proper use of the area of the rainforest already cleared (deforested or destroyed) in the Amazon could solve many problems. He points out that 20 percent of the area could produce 50 million tons of grains annually. Another 20 percent could be used for small farmers (around 900,000 of them if each got 20,000 hectares)."
Valentim continues, "The remaining 60 percent would be used to raise 100 million head of cattle. And all that, without cutting down a single, additional tree or burning so much as one hectare." [Marrying Growth and Preservation in Brazil's Amazon]

The restoration of entire ecosystems is most possible in regions where parts or at least remnants of the original forest still remain and there are few human population pressures. Small clearings surrounded by forest recover quickly and large sections may recover in time especially if we provide some assistance in the reforestation process. After several years, a once barren field can once again support vegetation in the form of pioneer species and secondary growth. Although the secondary forest will be low in diversity and poorly developed, the forest cover will be adequate for some species to return (assuming they still exist). In addition, the newly forested patch can be used for the sustainable harvest of forest products and low intensity logging.
Tracts of replanted forest may have ecological returns in addition to economic ones. In the short term, forests absorb large amounts of atmospheric carbon and the more trees that are replanted, the more atmospheric carbon will be sequestered. Replanting and rehabilitating secondary forests around the world has tremendous potential for offsetting greenhouse gas emissions. Furthermore, rehabilitated forest lands can attract ecotourists and sustain some native forest wildlife.
The extension of protection to critically important habitats within the Amazon region is key to maximizing survival of biodiversity in Brazil. Paramount to the success of conservation efforts:
Perhaps the best way to address deforestation in Brazil is developing a new conservation policy based on the principle of sustainable use and development of rainforests. Sustainable development is a phrase that has been used regularly over the past decade, but critics will quickly tell you that collecting fruits, latex, and nuts from the rainforests is not enough make a living let alone support a growing economy. "Sustainable development" should considered an underlying philosophy to be applied via policy to various agents and industries involved in the use and development of rainforest lands and resources.
Agriculture [more]
For thousands of years parts of the Amazon has been managed to sustain productive agriculture and at times, sustain dense human populations. It is estimated that more land was under cultivation in the Amazon on the eve of the arrival of Columbus than is today. The fact that certain forms of agriculture are possible is a vital consideration for the sustainable, economic development of tropical rainforests.
Actions to take:
What is desperately needed is a new form of forestry that departs from the older mentality where forests only exist to serve immediate human demands and are non-exhaustible resources. New forest management adds both rural development and conservation projects to traditional tree harvesting and aims to keep forests as functional ecological systems while providing multiple economic benefits.
Actions to take [more]:
Clearing for pastureland and land speculation purposes is a major cause of tropical forest loss, especially in Latin America. Cattle are an attractive investment for Amazonian farmers because they are a highly liquid capital asset with low marginal costs once forest has been cleared. Cattle are used to establish land claims on otherwise "unoccupied" rainforest land and can be used as a hedge against inflation.
Actions to take:
To remedy this wasteful use of land, lawmakers in Brazil should consider laws that restrict these practices. Or maybe lawmakers could enforce some of the existing laws like the 1996 law that forbade Amazon landowners from cutting more than 20% of the forest on their land. For whatever reason the laws on the books are not that effective -- deforestation has increased dramatically in the past couple of years.
Law Enforcement
Between the lack of resources, rampant corruption, and questions as to whether IBAMA even has any legal authority to enforce the law, the agency only collects 6.5% of the fines it imposes.
IBAMA estimates that 80% of all logging in the Amazon is illegal, but there's relatively little it can do about it. To effectively enforce existing environmental law, IBAMA is going to need more resources.
Conclusion
Biodiversity is makes life on Earth livable for our species. By extinguishing hotbeds of biodiversity like the Amazon rainforest we are destroying a part of ourselves. Biodiversity will recover after humanity is gone, but in the meantime, the continuing loss of our fellow species will make Earth an awfully crowded, but lonely place.
Past extinctions have shown it takes at least 5 million years to restore biodiversity to the level equal to that prior of the extinction event event. Our actions today will determine whether Earth will be biologically impoverished for the 500 trillion or more humans that will inhabit the earth during that future period.
The extinction event that is occurring as you read these words rivals the extinctions caused by natural disasters of global ice ages, planetary collisions, atmospheric poisoning, and variations in solar radiation. The difference is that this extinction was conceived by humans and subject to human decisions. We are the last, best hope for life as we prefer it on this planet.
