A spatially disaggregated global livestock dataset containing information on biomass use, production, feed efficiency, excretion, and greenhouse gas emissions for 28 world regions, 8 livestock product... moreion systems, 4 animal species (cattle, small ruminants, pigs, and poultry), and 3 livestock products (milk, meat, and eggs) for the year 2000.
The dataset highlights: (i) feed efficiency as a key driver of productivity, resource use, and greenhouse gas emission intensities, with vast differences between production systems and animal products; (ii) the importance of grasslands as a global resource, supplying almost 50% of biomass for animals while continuing to be at the epicentre of land conversion processes; and (iii) the importance of mixed crop–livestock systems, producing the greater part of animal production (over 60%) in both the developed and the developing world. These data provide critical information for developing targeted, sustainable solutions for the livestock sector and its widely ranging contribution to the global food system.

Lansdown pasture photograph series - nadir-pointing cameras on two separate 2.8m x 2.0m plots.
Series of digital photographs of pasture captured by two digital cameras 2.5 m above the ground in a dow... morenward-pointing position. Camera field of view approximately 2.8m x 2.0m at ground level. Images captured at 30 minute intervals from 2011-09-07 to 2013-08-10.
Cameras were Pentax Optio WG-1 digital cameras (13.8 megapixels). Images saved in JPG format.

Node 1080 (unfenced): Lon. 146.85090, Lat. -19.66113
Distance between nodes approx. 50m.less
CLOSED-Application real-time sensor net - A pilot project combining multispectral proximal sensors and digital cameras for monitoring tropical pastures - Published 08 Sep 2016
The data tables (inputs and results) supported "a quantitative assessment of the prospects for current and future biomass feedstocks for bioenergy in Australia, and associated estimates of the greenho... moreuse gas (GHG) mitigation resulting from their use for produc- tion of biofuels or bioelectricity." (from the Abstract of GCB Bioenergy, 4(2):148–175. [doi: 10.1111/j.1757-1707.2011.01115.x]).
