Primary productivity in Bahr Al-Najaf Depression Reservoir/Iraq
Kufa Journal for Agricultural Sciences, 2018 The primary productivity was calculated depending on pelagic and benthic biomass. Monthly samples were obtained from four study stations (February 2015 to January 2016). The pelagic primary productivity values were ranged between1.26 mg. cm-2.

Global urban expansion offsets climate-driven increases in terrestrial net primary productivity
Nature Communications, 2019 Robust estimates of either urban expansion worldwide or the effects of such phenomenon on terrestrial net primary productivity (NPP) are lacking. Here the authors used the new dataset of global land use to show that the global urban areas expanded ...

Potential Predictability of Net Primary Production in the Ocean
Global Biogeochemical Cycles, 2020 Interannual variations in marine net primary production (NPP) contribute to the variability of available living marine resources, as well as influence critical carbon cycle processes. Here we provide a global overview of near‐term (1 to 10 years) potential predictability of marine NPP using a novel set of initialized retrospective decadal forecasts ...

A critical overview of model estimates of net primary productivity for the Australian continent
, 2004 Net primary production. links the biosphere and the climate system through the global cycling of carbon, water and nutrients. Accurate quantification of net primary productivity (NPP) is therefore critical in understanding the response of the world's ...

Global evidence on nitrogen saturation of terrestrial ecosystem net primary productivity
Environmental Research Letters, 2016 The continually increasing nitrogen (N) deposition is expected to increase ecosystem aboveground net primary production (ANPP) until it exceeds plant N demand, causing a nonlinear response and N saturation for ANPP.

The Distributional impact of dams: Evidence from cropland productivity in Africa [PDF]
We examine the distributional impact of major dams on cropland productivity in Africa. As our unit of analysis we use a scientifically based spatial breakdown of the continent that allows one to exactly define regions in terms of their upstream ...
