Estimating Grazing Pressure from Satellite Time Series Without Reliance on Total Production
Remote SensingAccurately assessing grazing impacts is essential for sustaining alpine grasslands. Conventional approaches often rely on total forage productivity, an indirect and uncertain proxy for forage availability.

Fast rotational intensive grazing
, 2017 The increased demand for meat is driven by a rising human population, and a dramatic growth in meat consumption per person. Farmers and scientists have sought to curb the adverse environmental impacts of livestock by increasing production efficiency, and reducing its contribution to human consumption.

Carbon budgets for an irrigated intensively grazed dairy pasture and an unirrigated winter-grazed pasture [PDF]
Biogeosciences, 2016 Abstract. Intensification of pastoral agriculture is occurring rapidly across New Zealand, including increasing use of irrigation and fertiliser application in some regions. While this enables greater gross primary production (GPP) and livestock grazing intensity, the consequences for the net ecosystem carbon budget (NECB) of the pastures are poorly ...

Grazing Intensity and Spatial Heterogeneity in Bare Soil in a Grazing-Resistant Grassland [PDF]
Rangeland Ecology & Management, 2012 Abstract We used very large scale aerial (VLSA) photography to quantify spatial patterns in bare soil in the northeastern Colorado shortgrass steppe. Using three pairs of pastures stocked at moderate (0.6 animal unit months lAUM] · ha -1 ) versus very heavy (1.2 AUM · ha -1 ) rates, we detected greater bare soil under very heavy (mean = 22.5 ...

Proposition of an index of intensity of grass use [PDF]
, 2013 A. The widely used concept of intensity of grassland management can be defined according to the fertilization level and defoliation frequency for mown meadows or to the stocking rate for pastures.

Plant compensation to grazing and soil carbon dynamics in a tropical grassland [PDF]
PeerJ, 2014 The effects of grazing on soil organic carbon (SOC) dynamics, particularly in the tropics, are still poorly understood. Plant compensation to grazing, whereby plants maintain leaf area (C input capacity) despite consumption (C removal) by grazers, has ...

Land, 2022 Overgrazing is the key factor that has exacerbated grassland degradation in China’s pastoral regions. Herder’s grazing-based livestock production behavior becomes important to grassland conservation. Several formal environmental institutions and policies
