PROJECTION OF CLIMATE CHANGE IMPACTS ON NET PRIMARY PRODUCTIVITY OF THE LEGAL AMAZON – BRAZIL

نویسندگان

چکیده

The Amazon Rainforest is one of the main carbon sinks (CO2) on planet. However, recently, due to anthropic activities and climate change, it has lost its stability in CO2 absorption. Therefore, understanding dynamics future change scenarios becomes essential. We assess influence NPP (biomass) levels Forest using ML models. tested models were Bayesian, Linear Model, Random Forest. current scenario was evaluated 19 bioclimatic covariates (worldclim dataset). While based RCPs 2.6 8.5 (based MIROC5 HadGEM2-ES models). had best performance statistic (R² = 0.71 training 0.68 holdout-test). will imply an increase average for forest, especially with greater intensification RCP (2 7.69 % models, respectively). Forests (Evergreen Broadleaf areas) have fixation capacity. In general, forest increased capacity by end century.

Impacts of urbanization on net primary productivity in the Pearl River Delta, China

Great changes in land use/land cover from rapid urbanization have occurred in the PearlRiver Delta, China. As the primary cause of land development in the urbanization process,urban expansion has mostly occurred on land with higher NPP, significantly impacting theregional ecosystems. The primary purpose of this study was to reveal the impacts of urbanexpansion on the regional NPP. The land cove...

Impacts of tropospheric ozone and climate change on net primary productivity and net carbon exchange of China's forest ecosystems

Methods Using the dynamic land ecosystem model (DLEM) in conjunction with 10-km-resolution gridded historical data sets (tropospheric O3 concentrations, climate variability/change, and other environmental factors such as land-cover/ land-use change (LCLUC), increasing CO2 and nitrogen deposition), we conducted nine simulation experiments to: (1) investigate the temporo-spatial patterns of NPP a...
