The microscopic soybean cyst nematode (SCN) may be small, but it has a massive impact. This pest latches onto soybean roots, feeding on their nutrients and leaving a trail of destruction that costs farmers billions in yield losses each year. Unfortunately, current methods to combat SCN are faltering as the pest grows resistant to traditional controls. But new research is now offering a glimmer of hope.

 

Tree crops – for example, apple, cherry, olives, nuts, coffee, and cacao – cover more than 183 million hectares worldwide, yet remain largely overlooked in agricultural policies, despite their critical role in achieving the United Nation’s Sustainable Development Goals (SDGs). An international research team, with the participation of Göttingen University, highlight how these crops are not only essential to feed the world and for global economies, but also hold immense potential for protecting biodiversity and the climate, as well as improving livelihoods for millions of people worldwide. The findings were published in a Perspectives article in Nature Sustainability.

A new study has lifted the lid on five species of root-lesion nematodes living in maize crops across New Zealand - and suggested the existence of a hitherto-unsuspected cryptic species.

A new University of Houston study of hemp microbes may lead to more sustainable farming methods, using nature to boost the growth of the plant which has become increasingly popular for its versatile uses: CBD-rich varieties are in high demand for pharmaceutical products, while fiber-rich varieties are valued for industrial applications like textiles. 

The invasive emerald ash borer, according to the U.S. Department of Agriculture, was first found in the United States in southeast Michigan in 2002. In the decades since, the wood-boring beetle has spread east and west across the U.S. and Canada, killing tens of millions of ash trees, causing one of the costliest forest insect invasions to date. More than 90% of all ash infested by the insect native to Asia eventually die, threatening to make the tree species functionally extinct in North America. In response, researchers at Penn State are working with the U.S. Forest Service and other partners to identify and develop ash trees genetically able to withstand the beetles’ onslaught and strategize how to restore ash to forests.

Scientists have organized structural barriers to food systems change into a comprehensive framework, with the aim of empowering policymakers, civil society organizations, and researchers to tackle food sustainability challenges more effectively.
