Who's burning the rainforest?

Many people believe tropical rainforests, in the Amazon and elsewhere, are being destroyed by poverty-stricken people with no other means of making a livelihood or providing for their families. The sad truth is that very seldom is rainforest cut or burned by those with a genuine need.

In Brazil, 200 people own 90% of the cattle ranches in the country. Those ranches, mostly located in areas where there used to be rainforest or on clear partches within the Amazon, provide over four million head of cattle each year. These ranch owners are the ones responsible for a large part of the deforestation of the Brazilian Amazon.

Logging is another major cause of deforestation, and here again the situation is one of the rich getting richer, not of the poor taking advantage of the vast resources of the Amazon basin. In addition, many of the trees destroyed for logging purposes are neither useful nor desired - they are simply in the way of the valuable hardwood trees, many of which are sold with falsified approval documents.

Until recently, I was one of the many who believed that most of the deforestation of the Amazon was being done by people, indigenous or not, who had no other means of survival. This was something I had been taught somewhere along my education, and it was a fact which seemed to make sense - but the reality is very different.

When the Brazilian government begain construction of the Trans-Amazonian Highway in the 1970's the road was intended to encourage settlement in the Amazon, particualrly by poor Brazilians who had nowhere else to go. The government soon realized that the settlement plan was not bringing the results intended. Instead, the "highway" - a narrow, barely two-lane dirt road which turns to a sloppy, muddy, dangerous mess in the rain - was allowing penetration of the Amazon by cattle ranchers and loggers, among others.

Some of the burning which happens in the Amazon is done on the lands of indigenous tribes or by poor settlers. Much more, however, is done by a very different group of people. They use the "burning season" to exploit more areas of primary forest to enhance a profit which, usually, is already extensive.

Smoke over the Amazon

A few moments ago I was browsing the news in an effort to reaquaint myself with the happenings of the world after trekking the southern Amazon Basin with the National Outdoor Leadership School for the past 3 months. I came across a short piece on Al Jazeera which hit home - Smoke over the Amazon.

Over the past few months, I have often seen the same smoke Mr. Elizondo saw through the window of his plane, and occasionally from a much closer vantage point. I can recall seeing plumes of white or brownish-black smoke rising into the air and patches of blackened earth and trees where the fires had been. Once, while our bus was driving on the Trans-Amazonican Highway, we drove through a place where there were fires on both sides of the road. There was zero visibility within the haze. Neither we nor the driver could see the reddish ribbon of the highway for a few long moments. When we finally exited the cloud, the heavy scent of smoke remained with us.

A few of the fires which occur in the Amazon Basin are natural, started by lightning. In the serrado (or savanna) environments, fires are part of the natural cycle. Most of the fires, however, are man-made. They serve as the first step in clear-cutting the rainforest for agricultural use or farmland. According to data from the late 1990's (I'll update with more recent data when I have a chance to find it), over 20,000 km2 (7,722 square miles) of rainforest are cleared per year.

Until the rains come, this is still the Burning Season in the Amazon.

Expect more on my Amazon expedition, and more about rainforest ecology and deforestation, once I'm back in the US.
