Climate change may mean significant changes in crop productivity, including for planted forests, due to changes in climatic parameters. These impacts may be more intense in some regions of the country. Scientific investigation based on field data obtained over the long term and projected scenarios are important tools for planning and decision making that can help decrease vulnerability and risk for the forest sector in the near future. Along these lines, this study (which was conducted with support from Klabin S.A., a forest-based company) indicates changes that may be on the horizon, discusses climatic behavior in some regions of Brazil which are important centers for eucalyptus production, and projects impacts on productivity and carbon emissions/removal capacity in eucalyptus forests within the scenario of climate change. A highlight of this study is the use of the HadGEM2-ES model to predict rainfall, average temperature, evapotranspiration, water deficit, frost events, and minimum temperature at 10-year intervals until 2040. This is a differential, since other studies consider longer intervals. The study indicates climatic risk and the resulting impact on eucalyptus production in southern Brazil. However, detailed investigation in the municipalities of Itapetininga, Telêmaco Borba, and Otacílio Costa points to variations in the vulnerability of these environments. The study also examines the potential of these eucalyptus forests to accumulate carbon, indicating how and to what extent this function may be affected. Predicting potential changes is an intelligent way to prepare for and even ameliorate the impacts of climate change, thus making it possible to maintain the potential for the region and eucalyptus forests to make significant contributions to environmental quality and reaffirm the opportunities that are present for the forest sector within the context of the green economy and decarbonization of the economy.

The net primary production of tropical forests and its partitioning between long-lived carbon pools (wood) and shorter-lived pools (leaves, fine roots) are of considerable importance in the global carbon cycle. However, these terms have only been studied at a handful of field sites, and with no consistent calculation methodology. Here we calculate above-ground coarse wood carbon productivity for 104 forest plots in lowland New World humid tropical forests, using a consistent calculation methodology that incorporates corrections for spatial variations in tree-size distributions and wood density, and for census interval length. Mean wood density is found to be lower in more productive forests. We estimate that above-ground coarse wood productivity varies by more than a factor of three (between 1.5 and 5.5 Mg C ha−1 a−1) across the Neotropical plots, with a mean value of 3.1 Mg C ha−1 a−1. There appear to be no obvious relationships between wood productivity and rainfall, dry season length or sunshine, but there is some hint of increased productivity at lower temperatures. There is, however, also strong evidence for a positive relationship between wood productivity and soil fertility. Fertile soils tend to become more common towards the Andes and at slightly higher than average elevations, so the apparent temperature/productivity relationship is probably not a direct one. Coarse wood productivity accounts for only a fraction of overall tropical forest net primary productivity, but the available data indicate that it is approximately proportional to total above-ground productivity. We speculate that the large variation in wood productivity is unlikely to directly imply an equivalent variation in gross primary production. Instead a shifting balance in carbon allocation between respiration, wood carbon and fine root production seems the more likely explanation.
