Quantifying the contributions of climate factors and human activities to variations of net primary productivity in China from 2000 to 2020

Frontiers in Earth Science, 2023
Net primary productivity (NPP) plays a vital role in the globe carbon cycle. Quantitative assessment of the effects of climate changes and human activities on net primary productivity dynamics is vital for understanding the driving mechanisms of ...

Inventory of China’s Net Biome Productivity since the 21st Century

Land, 2022
Net biome productivity (NBP), which takes into account abiotic respiration and metabolic processes such as fire, pests, and harvesting of agricultural and forestry products, may be more scientific than net ecosystem productivity (NEP) in measuring ...

A new global oceanic multi-model net primary productivity data product [PDF]

Earth System Science Data, 2023
Net primary production of the oceans contributes approximately half of the total global net primary production, and long-term observational records are required to assess any climate-driven changes. The Ocean Colour Climate Change Initiative (OC-CCI) has

The 2010 spring drought reduced primary productivity in southwestern China [PDF]

, 2012
Many parts of the world experience frequent and severe droughts. Summer drought can significantly reduce primary productivity and carbon sequestration capacity. The impacts of spring droughts, however, have received much less attention.
