Greenhouses are quickly proliferating in response to the world’s increasing demand for food, but information on their precise location, distribution and extent remains limited in many countries. This Analysis combines global very-high-resolution satellite imagery and artificial intelligence to address this knowledge gap, showing a dramatic increase in greenhouse coverage in the Global South.
Harvest from inland recreational fisheries are estimated, demonstrating the importance of this food source for nutrition and economic value in food systems that are vulnerable to climate change.
Ongoing depletion rates of phosphorus reserves might pose a challenge to future food security. This Analysis estimates the effects of matching plant-available soil Olsen P concentrations with thresholds for optimal yields of grassland and 28 crops on the longevity of global P reserves.
A lack of systematized information on existing agri-environmental policies poses challenges for research and practice. A new database with more than 6,000 agri-environmental policies implemented over the past six decades around the world helps fill the gap. This information enables the extraction of valuable insights for policymakers, academics and businesses.
A trans-disciplinary framework shows how collaborative engagement and multi-phase development pathways can aid scaling up urban agriculture to transform food systems and support robust urban resilience and sustainability.
