University of Oxford finds trees inhale less carbon when they are drought impacted
March 5, 2015 07:34 AM - University of Oxford

For the first time, an international research team has provided direct evidence of the rate at which individual trees in the Amazonian basin 'inhale' carbon from the atmosphere during a severe drought. 

The researchers measured the growth and photosynthesis rates of trees at 13 rainforest plots across Brazil, Peru and Bolivia, comparing plots that were affected by the strong drought of 2010 with unaffected plots. They found that while growth rates of the trees in drought-affected plots were unchanged, the rate of photosynthesis – by which trees convert carbon into energy to fuel their activities – slowed down by around 10 percent over six months. Their paper, published in the journal, Nature, concludes that trees may be channelling their more limited energy reserves into growth rather than maintaining their own health. Computer simulations of the biosphere have predicted such responses to drought, but these are the first direct observations of this effect across tropical forests.

Massive Landfill Site Turns Into Thriving Eco-Park

Jacob Ryan, NoCamels

Israel’s largest landfill dump has undergone a massive makeover that has seen the mountain of garbage turn into a 2,000-acre ecological park three times the size of New York City’s Central Park. This new “green lung,” which includes a 150-acre recycling station, walking and cycling trails, ponds and extreme sports activities, will soon be home to a 50,000-seat amphitheater, one of the largest concert venues in Israel. And if that’s not enough, the biogas from this landfill, once a toxic pollutant, is now being reused as green energy.

The multi-million-dollar makeover of Hiriya, which started in 2001, has proven to benefit both the surrounding environment and visitors from all over the world. Now, what once was a huge dump between Road 4 and Road 461 in central Israel known for its unpleasant past, is no longer Israel’s ugliest site.
