North American agriculture: its contribution to the green house effect
This paper assesses the effect of agricultural systems and changing input use in North American agriculture on CO2 emissions. These emissions are linked to the greenhouse effect. In the early part of the 20th century, there was a significant increase in CO2 emissions as a large amount of land was diverted from its grassland state into cultivated cropland. CO2 emissions from North American ...

Is organic farming climate friendly?
Think organic farming is climate friendly? You might want to think again. A study published recently in the journal Agriculture and Human Values suggests that as organic agriculture emulates conventional industrial agriculture, the environmental benefits may not be the slam-dunk that Earth-loving proponents might like them to be. It’s well known that organic practices offer climate ...

Project - Climate Feed
Seaweed in cattle feed to reduce greenhouse gas from burping dairy cows Seaweed could contribute to reducing greenhouse gas emissions from agriculture. The research project Climate Feed will develop seaweed feed supplement with funding from Innovation Fund Denmark. There’s a huge potential in reducing cows’ emission of methane and, consequently, greenhouse gases. The major part of ...

Air emissions of ammonia and methane from livestock operations: Valuation and policy options
The animal husbandry industry is a major emitter of ammonia (NH3), which is a precursor of fine particulate matter (PM2.5) —arguably, the number-one environment-related public health threat facing the nation. The industry is also a major emitter of methane (CH4), which is an important greenhouse gas (GHG). We present an integrated process model of the engineering economics of technologies to ...

Not just hot air — global diplomacy and the search for a successor to Kyoto
Every winter the gates of Copenhagen's famous Tivoli Gardens, an old world amusement park in the city centre, open to officially mark the beginning of the extended Christmas period. This December the twinkling lights of Tivoli will most likely be outshone by COP 15 — the most important global climate change meeting ever — as thousands of diplomats, politicians, business people, environmentalists ...

Greenhouse gas, animal performance, and bacterial population structure responses to dietary monensin fed to dairy cows
Received for publication January 27, 2009. The present study investigated the effects of a feed additive and rumen microbial modifier, monensin sodium (monensin), on selected variables in lactating dairy cows. Monensin fed cows (MON, 600 mg d–1) were compared with untreated control cows (CON, 0 mg d–1) with respect to the effects of monensin on the production of three greenhouse gases (GHG), ...

A new tool to measure and reduce emissions from agriculture
Agriculture is a major actor in spurring global climate change. The sector is already responsible for at least 10-12 percent of global greenhouse gas (GHG) emissions, and agricultural emissions are expected to increase by more than 50 percent by 2030. Mitigating agricultural emissions, then, could go a long way toward mitigating global climate change. The Greenhouse Gas Protocol is currently ...

Boris Johnson sets out his ten-point green plan
Where are food and farming in the ten-point green plan? Along with colleagues across the environmental movement, I have been anticipating Boris Johnson’s Green Speech today, where he set out a 10-point plan for how the UK will meet Net-Zero. All eyes were on the landmark new commitment to bring forward the ban on petrol and diesel car sales to 2030. But where were food and farming? If we ...

Research highlights cattle emissions reduction opportunity - Case study
Researchers in Denmark have measured the quantities of greenhouse gases in the breath of dairy cows and demonstrated a heritable variability between individual animals. Researchers in Denmark have measured the quantities of greenhouse gases in the breath of dairy cows and demonstrated a heritable variability between individual animals. “This means that we have an opportunity to select for ...

Food for Thought on Earth Day 2021
Change a habit, plant a tree or fill a garbage bag on your local hiking trail April 22 (and every day after). It was 1970. The Beatles disbanded and Jimi Hendrix died. There were just over 3.6 billion people in the world. The Boeing 747, the first jumbo-jet, made its inaugural flight from New York to London. Nixon was president. The U.S. Environmental Protection Agency was born. And people ...

Research highlights cattle emissions reduction opportunity
Researchers in Denmark have measured the quantities of greenhouse gases in the breath of dairy cows and demonstrated a heritable variability between individual animals. “This means that we have an opportunity to select for breeding those individuals which will produce offspring that generate less methane,” says Dr Jan Lassen who led the research project on individual methane ...

Reducing the Effects of Methane from Cows in Cattle Farming with Methane Monitors
In 2018, there were an estimated 1.002 billion head of cattle worldwide, an increase of 6.5 million head over 2017.1 Global meat production has continued, and is seemingly continuing, to rise and although cattle now accounts for a relatively smaller percentage of overall meat consumption, there were still over 68 billion tonnes of cattle meat produced in 2014.2 Beef exported from the US alone in ...
