Crop Yield Estimation in the Canadian Prairies Using Terra/MODIS-Derived Crop Metrics

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
We evaluated the utility of Terra/MODIS-derived crop metrics for yield estimation across the Canadian Prairies. This study was undertaken at the Census Agriculture Region (CAR) and the Rural Municipality (RM) of the province of Saskatchewan, in three ...

The allocation of ecosystem net primary productivity in tropical forests [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2011
The allocation of the net primary productivity (NPP) of an ecosystem between canopy, woody tissue and fine roots is an important descriptor of the functioning of that ecosystem, and an important feature to correctly represent in terrestrial ecosystem models.

Community level offset of rain use- and transpiration efficiency for a heavily grazed ecosystem in inner Mongolia grassland.

open access: yesPLoS ONE, 2013
Water use efficiency (WUE) is a key indicator to assess ecosystem adaptation to water stress. Rain use efficiency (RUE) is usually used as a proxy for WUE due to lack of transpiration data.

Fire intensity impacts on post-fire temperate coniferous forest net primary productivity [PDF]

open access: yesBiogeosciences, 2018
Fire is a dynamic ecological process in forests and impacts the carbon (C) cycle through direct combustion emissions, tree mortality, and by impairing the ability of surviving trees to sequester carbon.

Future supply and demand of net primary production in the Sahel [PDF]

open access: yesEarth System Dynamics, 2016
Abstract. In the 21st century, climate change in combination with increasing demand, mainly from population growth, will exert greater pressure on the ecosystems of the Sahel to supply food and feed resources. The balance between supply and demand (annual biomass required for human consumption) serves as a key metric for quantifying basic resource ...
