Hydropower Projects Depend On Rainforest Conservation

Deforestation Will Undermine Water Projects

Although controversial in many regards, large hydro-power projects are a source of clean energy production once in place. This energy source is dependent upon natural rainfall, which means these regional projects must conserve the rainforest to avoid disruptions in rainfall, which can decrease the amount of power generated by the plant.

New research recently published in the journal Proceedings of the National Academy of Sciences shows that a necessary part of increasing the electricity produced by hydro-power projects is conserving the local habitats.

The research explains that conserving rainforests in the Amazon River Basin will increase the amount of electricity produced by hydro-power projects in the region, and is the first study of its kind to quantify the impact regional rainforest cover has on energy production.

According to the findings from the report, rainforests are more critical than previously understood in generating the rainfall that drives river flow, and subsequently power generation, in tropical areas. Conversely, if deforestation continues to increase in the Amazon Rainforest, energy projections for the Belo Monte dam in Brazil will decline by one third.

“Our study shows that the huge strides Brazil has made in slowing Amazon deforestation are actually helping secure the nation’s energy supply,” says Claudia Stickler, the study’s lead author and scientist at the Amazon Environmental Research Institute International Program (IPAM-IP) who provided their progress to Phys.org. “But these efforts must continue hand-in-hand with conservation at the regional level.”

Bloomberg New Energy Finance reported earlier this year that large hydro would be the largest form of clean energy production by 2030, so understanding how best to facilitate that production is a necessary next step.

The research showed that if Amazon Rainforest deforestation continues unchecked the energy output supplied by the Belo Monte Dam — which will be one of the world’s largest dams upon completion — would fall by approximately 30 percent, equivalent to increasing four million more Brazilians into the world.

“These results are extremely important for long-term energy planning,” explains climatologist Marcos Costa, one of the study’s authors from the Federal University of Viçosa in Brazil. “We are investing billions of dollars in hydropower plants around the world. The more rainforests left standing, the more water we’ll have in the rivers, and the more electricity we’ll be able to get from these projects.”

The research ran simulations working from various levels of rainforest deforestation and found that rainfall is currently 6-7 percent lower than it would be with full forest cover. If, by 2050 the estimates of 40 percent deforestation occur as some experts predict, then rainfall will be 11-15 percent lower which will result in 35-40 percent less power.

Sacred Seedlings is a global initiative to support forest conservation, reforestation, urban forestry, sustainable agriculture and wildlife conservation. Sustainable land management and land use are critical to the survival of entire ecosystems. Sacred Seedlings is a U.S.-based program that supports the vision of local stakeholders. We have projects ready across Africa. We seek additional projects elsewhere around the world. We also seek volunteers, sponsors and donors of cash and in-kind support.
