The economics of making fish feed with 'stranded' methane

Methane, a powerful greenhouse gas, can be captured and transformed into protein-rich feed for farmed fish – an increasingly important food sector. A new analysis shows how to make the approach more cost-effective than current fish feeds.

Deforestation

COP26: Promise and limits of vows to rein in methane and protect forests

Stanford experts discuss strengths and weaknesses of major pledges at the UN climate summit that target methane emissions and deforestation.

Methane and climate change

Nations around the world are joining a pledge to curb emissions of methane, and the Biden administration is proposing stricter regulation of the potent greenhouse gas. Explore Stanford research about methane emissions and promising solutions.

Growing climate solutions

A bill under debate in Congress would pave the way to verifying and paying for farms’ carbon savings. Stanford scientists explore this and other opportunities for growing climate change solutions on U.S. farms.

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.

Fish market in Vietnam

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.

Mapping conflicts over marine resources

Scientists Elizabeth Selig and Colette Wabnitz discuss their efforts to systematically map the patterns and drivers of marine resource conflicts in sub-Saharan Africa, and how the work may guide more just management and policy solutions. (Source: Center for Ocean Solutions)

Cornfield

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.

Crops with industry pollution in background

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.

Recharge pond

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.

Fish swimming in plastic debris

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.

Food

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.
