Today, more than half of all the fish, mussels, crustaceans, and algae consumed worldwide come from aquaculture – and the numbers are rising. Freshwater aquaculture, in particular, is considered a highly promising way to produce animal protein in a resource-efficient and environmentally friendly way. It has the potential to make a significant contribution to global food security while reducing the pressure on wild ecosystems. A joint Policy Report published today by the German National Academy of Sciences Leopoldina and the Brazilian Academy of Sciences (Academia Brasileira de Ciências, ABC) explores what sustainable and circular aquaculture could look like in practice in both Germany and Brazil. The report also offers concrete recommendations for policy-makers, administrative authorities, and researchers.
A sweeping new review reveals how satellites are helping scientists track a quiet but widespread shift in global agriculture: the abandonment of cropland.
In the face of rising urbanization and food insecurity, a new study published in Engineering explores the potential of urban aquaponics to enhance food security and reduce environmental impacts. The research, led by Qiuling Yuan and Fanxin Meng from Beijing Normal University, provides a comprehensive framework for assessing the sustainability of aquaponics systems in urban areas, selecting Beijing as a case study. The findings suggest that urban aquaponics can significantly improve water efficiency and local food self-sufficiency while reducing energy consumption and carbon emissions through optimized strategies.
A new study in Forest Ecosystems reveals how fire history, vegetation type, and soil features jointly influence carbon storage in boreal forests. Researchers in Norway compared pine and spruce forests across regions with different fire legacies, and they found that pine forests store nearly twice as much organic carbon as spruce forests, with charcoal carbon stocks varying by region due to fire frequency, terrain microtopography, and organic layer depth. The study highlights the importance of localized forest management strategies for sustaining carbon storage in the face of climate change.
