Researchers from the Smithsonian Tropical Research Institute and Earthwatch met in Panama from Mar. 1-5 to present mid-term research results from the HSBC Climate Partnership, a five-year initiative to identify and respond to the impacts of climate change. The program is supported financially by HSBC and involves a global team of bank employees -- 'climate champions' -- in vital forest research.
The first-ever research program of its kind has so far:
Researchers working in broadleaf forest plots near Oxford, England, Atlantic rainforests in Southern Brazil and subtropical forests near Gutianshan Nature Reserve in China, as well as the SERC site in Maryland, have been putting HSBC employees to work. At Oxford, for example, data collected indicates that changes in forest structure have impacted moth populations.
Stuart Davies, director of the Smithsonian's Center for Tropical Forest Science, says, "We know that carbon dioxide in the atmosphere has shot up from 280 to 385 parts per million since the 1850's as a result of human activities like the burning of fossil fuels and deforestation. The degree to which atmospheric carbon dioxide levels continue to increase depends, in part, on how trees respond to climate and atmospheric change -- whether forests end up storing more or less carbon. This is what the HSBC Climate Partnership research is trying to establish."
Dan Bebber, head of climate change research at Earthwatch, says, "Human activities are undeniably changing the world's climate, but the effects of that change on forest ecosystems and the role that forests play in providing ecosystem services such as carbon storage are poorly understood. The research being supported by funding and climate champions from HSBC will help to increase our knowledge of forests, and how they can be wisely managed for the future. This unique NGO-corporate partnership is an exemplary model of how individuals and businesses can make a difference."
STRI staff scientist Helene Muller-Landau said: "The HSBC Climate Champions working with us to measure trees understand how to take stock of carbon balances. Trees take up carbon as they grow. As trees die and decompose, they release carbon. The balance of carbon flows in and out of the forest determines whether the total forest carbon stock increases or decreases over time."
"Dangerous and irreversible changes that threaten life-support systems are likely when atmospheric carbon levels reach 550 ppm, if not sooner," stressed Yavinder Malhi, research scientist from Oxford University. "It's our job to engage people in science in a way that balances keeping things simple while showing that forests, as living systems, may be really complicated, taking up carbon under some conditions and giving off carbon under other conditions."
Research in Peru reveals how forest carbon budgets change with temperature from cooler mountainous sites to warmer lowland sites. Muller-Landau and Malhi agree that because different tree species respond differently to changing temperatures and rainfall regimes, some species will thrive while others will decline, resulting in changes in forest tree species composition and probably in carbon stocks.
Another important topic of discussion at the conference was the HSBC-sponsored Panama Canal Watershed Experiment, nicknamed the Agua Salud Project. This huge experiment aims to establish how different land uses -- pasture, grass, native tree plantations, teak or mature forest -- affect carbon storage, water flow throughout both wet and dry periods during the year and biodiversity on the narrow Isthmus of Panama, where two great biodiversity hotspots meet. STRI Director Eldredge Bermingham noted "that locating this experiment on the banks of the Panama Canal aims to focus global attention on the ecosystem services that forests provide this critical commercial waterway."
