Blue food revolution
Hunger, malnutrition and obesity affect billions of people. A first-of-its-kind comprehensive review of the so-called blue foods sector reveals challenges and opportunities for creating a healthier, more sustainable, equitable and resilient global food system.
Study suggests rising and shifting demand for seafood by 2050
Humanity is likely to consume more fish and shellfish in the coming decades. Preparing for that future requires better data on the types of fish that people eat, sustainable expansion of aquaculture and improved understanding of the local context for the food on our plates.
Global warming increased U.S. crop insurance losses by $27 billion in 27 years
Higher temperatures attributed to climate change caused payouts from the nation’s biggest farm support program to increase by $27 billion between 1991 and 2017, according to new estimates from Stanford researchers. Costs are likely to rise even further with the growing intensity and frequency of heat waves and other severe weather events.
Using nature's miracle bugs to help feed the world
It takes massive energy to make nitrogen fertilizer. Modified bacteria can do it at room temperature.
Cleaner air has boosted U.S. corn and soybean yields
The analysis estimates pollution reductions between 1999 and 2019 contributed to about 20 percent of the increase in corn and soybean yield gains during that period – an amount worth about $5 billion per year.
Summer reading: Igniting curiosity about Earth and imagining our future
Faculty at Stanford's School of Earth, Energy & Environmental Sciences recommend these 29 books for your summer reading.
Finding the 'sweet spots' for managed aquifer recharge
Rapidly worsening drought and a mandate to bring aquifer withdrawals and deposits into balance by 2040 have ignited interest in replenishing California groundwater through managed aquifer recharge. Stanford scientists demonstrate a new way to assess sites for this type of project using soil measurements and a geophysical system towed by an all-terrain vehicle.
Climate change has hurt farm productivity
New research shows climate change has wiped out seven years of improvements in agricultural productivity over the past 60 years.
Aquaculture’s promise and peril
Twenty years ago, a Stanford-led analysis sparked controversy by highlighting fish farming’s damage to ocean fisheries. Now a follow-up study takes stock of the industry’s progress and points to opportunities for sustainable growth.
Small-scale fisheries offer strategies for resilience in the face of climate change
Small-scale fisheries, which employ about 90 percent of the world’s fishers and supply half the fish for human consumption, are on the frontlines of climate change. They may offer insights into resilience.
Plastic ingestion by fish is a growing problem
A new research review finds the rate of plastic consumption in fish has doubled in the past decade and continues to increase. Fish higher up on the food chain are at the greatest risk.
Landscape disruptions threaten Paris climate agreement goals
A new study finds emissions from deforestation, conversion of wild landscapes to agriculture, and other changes in land use worldwide contributed 25 percent of all human-caused emissions between 2001 and 2017.
Community conservation reserves protect fish diversity in tropical rivers
Freshwater ecosystems across the world have experienced rapid species declines compared to ecosystems on land or in the ocean. New research shows that small, community-based reserves in Thailand’s Salween River Basin are serving as critical refuges for fish diversity.
Reducing global food system emissions key to meeting climate goals
Reducing greenhouse gas emissions from food systems will be vital for reaching climate goals – and it will require coordinated action across sectors and between national governments, according to new research.
U.S. corn crop increasingly sensitive to drought
New management approaches and technology have allowed the U.S. Corn Belt to increase yields despite some changes in climate. However, soil sensitivity to drought has increased significantly, according to a new study that could help identify ways to reverse the trend.
Why laughing gas is a growing climate problem
Nitrous oxide, also known as “laughing gas,” is the most important greenhouse gas after methane and carbon dioxide and the biggest human-related threat to the ozone layer. Now, emissions of the gas are rising faster than expected.
More food from the sea by 2050
If sustainably managed, wild fisheries and mariculture could help meet the rising demand for food in the long term.
Exploring the sustainability of the Indian sugar industry
Researchers analyzed the interconnected food, water and energy challenges that arise from the sugar industry in India – the second-largest producer of sugar worldwide – and how the political economy drives those challenges.
Q&A: Upscaling sustainability
Stanford scientists discuss obstacles for large-scale green initiatives and what it takes for sustainability efforts to deliver lasting benefits across borders, sectors and communities.
