A SCOTS research team has warned a worldwide rubber shortage is looming as demand grows, costs rise and an adequate man-made substitute is yet to be found.
The natural commodity used throughout modern life is dwindling to such an extent that Royal Botanic Garden Edinburgh researchers said if farmers in Africa and Asia continue to fell trees at the current rate more than half of the world’s main source of the critical plant will be gone in 30 years.
It means an impending rubber shortage that would affect production of everything from wellington boots to aviation tyres and scientists are calling for better management methods and policies in major producing countries including China, Vietnam, Thailand and Laos.
Hundreds of food companies have promised to keep their suppliers from cutting down forests. A global coalition of environmental groups is watching to see if the companies are keeping their promises.
Efforts by the Brazilian government over the past 15 years to curb deforestation have been a widely celebrated success, but a new study finds that there’s more deforestation happening in Brazil than official accounts suggest.
The study, led by researchers from Brown University, compared data from Brazil’s official Monitoring Deforestation in the Brazilian Amazon by Satellite Project (PRODES) with two independent satellite measures of forest cover. The study found that about 9,000 square kilometers of forestland not included in PRODES monitoring were cleared from 2008 to 2012. That’s an area roughly the size of Puerto Rico.
“PRODES has been an incredible monitoring tool and has facilitated the successful enforcement of policies,” said Leah VanWey, co-author of the research and senior deputy director at the Institute at Brown for Environment and Society. “But we show evidence that landowners are working around it in ways that are destroying important forests.”
The research is published in the journal Conservation Letters.
