Cassava is a crucial crop for 110% growth in global food demand, with potential for yield improvement through boosting sunlight conversion. Researchers are urging more research to address climate change and sustain yields.
Researchers are one step away from starvation due to increased global food demand and climate change. They are developing a method to engineer crops that can increase photosynthesis under high CO2 and temperature conditions.
The University of Maryland School of Public Health will lead a $10 million grant from the USDA to develop innovative, safe and sustainable ways to irrigate food crops in variable climates. The CONSERVE Center of Excellence aims to identify alternative water sources and new treatment technologies for contaminant-free irrigation.
Small farmers, often women, are preserving traditional crop varieties and landraces, providing vital resources for their livelihoods. Peri-urban and marginal locations are key areas where this preservation is occurring, with urban markets driving demand for local foodstuffs.
Scientists have developed tools to observe nitrogen uptake in real-time, improving understanding of the process and potentially increasing crop yields. The technology allows for the study of transport proteins involved in nitrogen absorption, enabling the development of more efficient agricultural practices.
A recent study under realistic field conditions found reassuringly low levels of pharmaceuticals and personal care products (PPCPs) in crops grown with treated wastewater for irrigation. Leafy vegetables absorbed the highest amounts of PPCPs, including a medication for epilepsy; triclosan, an anti-bacterial ingredient; and caffeine.
