Watch this Video on Roads and Rain Forests

That roads cause deforestation has been known for decades, documented in scholarly and anecdotal accounts. But this outstanding video from may be the most effective telling of this roads-and-forests story yet! Watch it. If you care about nature and have a sense of humor you'll want to laugh and cry at the same time.

Roadlessness was at the center of policy battles over US public lands in the 1990s.  Now it's gaining some traction in the tropics, where the advance of roads has fragmented nature into smaller and smaller bits, condemning certain species, especially large predators, as well as indigenous cultures that depend on not having contact with the modern world.

On a clear day from the top of western Panama’s 11,400-foot Volcán Barú, you can see the Pacific Ocean to the south and the azure Caribbean to the north. A little harder to spot is the best route around the dormant volcano, the centerpiece of the 35,000-acre Volcán Barú National Park. In 2003, CSF and The Nature Conservancy (TNC) performed an analysis to find out.

Do you want help designing an analysis or research project?

CSF is opening a program of “office hours” with experts who will help you figure out what to analyze and how. These consultations are free and an exclusive service for graduates of CSF courses..

Here’s how it works: Click on the link below and provide some basic information about the issue, problem, policy or activity you want to analyze. We’ll gather the ideas and set up a meeting for you with a member of our staff or one of our consulting experts via videoconference or telephone.

Examples of analyses we will help you design could include

• cost-benefit analysis of a sustainable development project,
• revenue strategy for a protected area,
• formulation of arguments to confront a specific environmental threat,
• economic valuation of an ecosystem or protected area,

Why Rebuild BR-319? Economics of an Amazon Road

The route that once connected Manaus and Porto Velho is in a state of serious disrepair and has been impassable since 1986. The reconstruction of this route as part of the federal Accelerated Growth Plan (known by its Portuguese acronym PAC) has projected costs of R$557 million (US$265 million), which is that our analysis focuses on. Our analysis takes two scenarios: a “conventional” one, which reflects the approach commonly used in the evaluation of projects for road infrastructure, and an “integrated” scenario, which aims to incorporate environmental costs in the conventional scenario.

Imazon: Brazilian parks near big infrastructure are more deforested

That doesn't really seem like news. We've known for a long time, intuitively and then empirically, that deforestation happens in places with easier access. Roads in the Amazon and other remote regions have been the most important vectors of deforestation. Farming in places where you can get supplies in and produce out cheaply is economically attractive.
