Combating deforestation of the Amazon and the promotion of large-scale reforestation initiatives aimed at increasing carbon storage in terrestrial biosphere are essential strategies to prevent further climate change, according to evaluation made by the participants of the 5th Regional Conference on Global Climate Change (on 05/06/2018).
Conducted by the Center for Research on Climate Change in partnership with the Energy and Environment Institute of the University of São Paulo (IEE-USP) and the Institute of Astronomy, Geophysics and Atmospheric Science (IAG-USP), the event has intended to celebrate the anniversary of 90 years of physicist José Goldemberg, President of FAPESP (Foundation for the Support of Research of São Paulo), and recognize his expressive performance in the debate on the role of renewable energies in the development, sustainability of forests and negotiations for combating climate changes.
Carlos Nobre, Coordinator of the National Institute of Science and Technology for Climate Change -supported by FAPESP and CNPq in the State of São Paulo – talked about how the impacts caused by land use change may impair the ability of Amazon rainforest to sustainability.
Carlos Nobre remembered that, from the years 1970, the Amazonian countries adopted a replacement model of the forest to expand their farmland, which put at risk the idea that Amazon is an essential element for the planetary stability for its ability to store carbon, regulate the hydrology and energy balance in various regions and shelter at least 10% of the biodiversity of the planet, among other factors.
Carlos Nobre commented on his participation in surveys which allowed raising the hypothesis of the savannization of the forest. According to this theory, if deforestation reaches a certain limit, around 40% the regional climate change is so profound that the cleared area will never be a forest and take features of Savannah.
