The upcoming book In Defence of Farmers: The Future of Agriculture in the Shadow of Corporate Power, edited by Jane W. Gibson and Sara E. Alexander, uses case studies of farmers to explore the tensions between conflicting views of the role of industrial agriculture.

A new method for monitoring nutrient concentrations in pasture in real time - using a small near-infrared spectroscopy device - could allow farmers to improve productivity by adjusting livestock grazing patterns, according to this paper.

Israeli startup Taranis has raised $20 million in funding for its aerial imaging technology, which uses multispectral images from satellites, planes and drones to scan fields. Artificial intelligence then identifies threats such as insects, crop disease, weeds and nutrient deficiencies. The company claims its technology can increase crop yields by up to 7.5%.

In a column for the Guardian, George Monbiot writes about the potential to create food without plants, animals or soil, using instead bacteria that feed on hydrogen (generated by solar-powered electrolysis of water) and carbon dioxide from the air. Monbiot argues that this form of food production could eventually drastically reduce the amount of land needed for the global food supply chain, and suggests that the new foodstuff could be used as an ingredient in processed foods.

In the book The End of Animal Farming, author Jacy Reese examines the social forces, technologies and activism that he argues will lead to the end of animal agriculture.

Growing millet next to a woody shrub native to West Africa could increase biomass by over 900% compared to growing millet alone, according to this paper. The shrub, Guiera senegalensis J.F. Gmel, has tap roots that can reach water deep in the soil. The study traced the movement of water from the shrub’s deep roots to the millet stems in a simulated drought.

This report from the UK’s Agriculture and Horticulture Development Board reviews how the behaviour of farmers might be influenced so that the recommendations of researchers and policymakers can be implemented on farms.

The book “Food and sustainability”, edited by Paul Behrens, Thijs Bosker and David Ehrhardt, is a textbook that addresses food sustainability from a multidisciplinary perspective.

California agritech startup Iron Ox has unveiled an “autonomous farm”, where robots move plants and transplant them from one stage to the next. Artificial intelligence controls pests and diseases and adjusts growing conditions. The farm is not entirely automated, as humans still sow seedlings and package the harvested crops. The farm produces leafy greens and herbs.
