Carbon dynamics, net primary productivity (NPP) and human appropriated NPP (HANPP) across a forest‐cocoa farm landscape in West Africa [PDF]

, 2019
Terrestrial net primary productivity (NPP) is an important metric of ecosystem functioning; however, there is little empirical data on the NPP of human-modified ecosystems, particularly smallholder,perennial crops like cocoa (Theobroma cacao), which are extensive across the tropics.

Spatio-temporal Patterns of Net Primary Production(NPP) in Weihe Watershed(China) and its Response to Environmental Factors [PDF]

, 2020
Carnegie-Ames-Stanford Approach and CA-Markov models are coupled to simulate and predict NPP in the Weihe Watershed to explore the spatial and temporal distribution of NPP and its dynamic changes. Correlation analysis was used to quantitatively evaluate the NPP response to environmental factors.Results showed that: (1) Seasonal and periodic changes ...
