Spread of diseases in farmed animals shown using social network analysis

Researchers have shown that looking at movements of operators and vehicles between farms in the same way we look at contacts in social networks can help explain the spread of dangerous infectious diseases of livestock, such as foot-and-mouth disease and avian influenza.

Urban cropland loss puts harvests at risk

Soils face a global threat as population pressure, human development and swelling cities lead to mounting cropland loss

Researchers use genes as early warning system for harmful algae blooms

Saving irrigation water with superabsorbent polymers

Soil conditioners called superabsorbent polymers have the potential to reduce irrigation needs for agricultural crops by storing water and nutrients and then releasing them in drought conditions, according to a recent article.

Blending wastewater may help California cope with drought

Researchers at UC Riverside have developed an economic model that demonstrates how flexible wastewater treatment processes which blend varying levels of treated effluent can create a water supply that benefits crops and is affordable.

Large carnivores under threat as prey they depend on decline

Up to 60 per cent of prey species of iconic predators, such as the clouded leopard, are threatened, which puts them at risk of extinction, too

The oceans are full of barriers for small organisms

Subtle and short-lived differences in ocean salinity or temperature function as physical barriers for phytoplankton, and result in a patchy distribution of the oceans’ most important food resource.
