Abstract Agribotix conducted a post hoc test of two vegetation indices, VARI and TGI, that used only the three visible-band signals from an unmodified CMOS camera. The results were compared to NDVI, which is generally considered to be a reliable measure of field health and the underlying RGB image. While the results are somewhat encouraging in limited cases, it is clear that neither VARI nor ...

For three weeks every month, Ray Archuleta captivates audiences with a few handfuls of soil. He begins with two clumps, dropping them into water. The soil from a farm where the soil isn’t tilled holds together, while the tilled soil immediately disperses, indicating poor soil structure. Next, volunteers from the audience — mostly farmers and ranchers — pour water over a soil ...

Abstract Aims As an exotic species colonises a new continent, it must overcome enormous environmental variation in its introduced range. Local adaptation of introduced species has frequently been observed at the continent scale, particularly in response to latitudinal climatic variation. However, significant environmental heterogeneity can also exist at the landscape scale. ...

Water is an important factor of production and livelihood support in rural communities. Meanwhile, water shortage is a virtually common feature in many arid and semi-arid countries. It is also projected that water stress will be exacerbated in such regions because of climate change. The cumulative effects of these stressors can potentially increase agricultural water vulnerability (AWV). ...

A large number of farmers' livelihoods are susceptible to cyclones and floods, and farmers are taking up several adaptation mechanisms. Previous studies, therefore, have examined determinants of various adaptation options and provide policy suggestions to promote a specific one. However, options are undertaken at different points depending on the nature and intensity of extreme events. ...

Agricultural pesticides that are known endocrine disrupting chemicals (EDCs) have been detected in waters in the Great Barrier Reef (GBR) catchment and lagoon. Altered transcription levels of liver vitellogenin (vtg) have been documented in wild populations of 2 GBR fisheries species, and were strongly associated with pesticide‐containing run‐off from sugarcane plantations. Here, we examine ...
