Agriculture is the cultivation of plants, animals, and some other organisms, such as fungi, for the production of food, fibre, fuel, and medicines used by society.
Food security remains a major global challenge, which is only amplified by ongoing climate change. Here, I look back on a 2015 paper on climate change impacts on wheat and discuss subsequent research on agriculture and food security.
A conserved nematode pheromone, ascr#18, primes plant immunity via chromatin remodeling dependent on the receptor kinase NILR1, enabling enhanced defense gene activation and broad-spectrum disease resistance across multiple plant species.
China’s plant-based food supply provides much of the population’s energy and nutrient needs, but key micronutrient gaps persist. Nutrient coverage can be strengthened by reducing food loss and waste, increasing whole-grain use, moderating red meat intake and repurposing crops from feed and non-food uses to direct human consumption.
Tillage can provide key ecosystem services for non-chemical management of cover crops and weeds, pests, and soilborne pathogens, without undermining soil organic carbon stocks or greenhouse gas emission reduction goal, based on a perspective on tillage as a strategic practice.

Adaptive multi-paddock grazing can improve soil carbon storage, pasture productivity and farm profitability, but enteric methane and the constraints of intensive global farming underscore the need for broader interventions.
