Two crops or one? Sometimes, growing two crops simultaneously on the same piece of land – called intercropping – can benefit farmers. But it needs careful planning and resource management.
In some parts of Africa, farmers intercrop sorghum – a grain – and peanuts. But they face a major information gap. There hasn’t been much research on optimal levels of fertilizer use for intercropping sorghum and peanuts in these areas.
A new study has filled this information gap. Researchers from Niger, Mali, and the United States have developed a method to help farmers determine how much fertiliser to apply when intercropping.
Redrawing the global map of crop distribution on existing farmland could help meet growing demand for food and biofuels in coming decades, while significantly reducing water stress in agricultural areas, according to a new study. Published today in Nature Geoscience, the study is the first to attempt to address both food production needs and resource sustainability simultaneously and at a global scale.
The results show that “there are a lot of places where there are inefficiencies in water use and nutrient production,” says lead author Kyle Davis, a postdoctoral researcher with Columbia University‘s Earth Institute. Those inefficiencies could be fixed, he says, by swapping in crops that have greater nutritional quality and lower environmental impact.
For early career researchers spanning plant and crop science and those in aligned areas such as pathology, entomology, bioinformatics, engineering and robotics: NIAB wishes to support outstanding early career researchers in applications for independent research fellowship such as:
Abandoned sugarcane plantations across the tropics could offer us a realistic, sustainable alternative to fossil fuels.
Ethanol produced from sugarcane has been one of the most successful short-term strategies to date in decarbonising energy supply, particularly in Brazil where the sugarcane ethanol system results in just 14% of the CO2 emissions of petroleum. In 2012 Brazil became the first country in which more bioethanol was used in cars than petroleum.
