Impact of climate change on food production - modelling study predicts over 500,000 extra deaths in 2050

Climate change could kill more than 500000 adults in 2050 worldwide due to changes in diets and bodyweight from reduced crop productivity, according to new estimates published in The Lancet. The research is the strongest evidence yet that climate change could have damaging consequences for food production and health worldwide. The modelling study, led by Dr Marco Springmann from the...

Joint Programming Initiative on Agriculture, Food Security and Climate Change launches updated Strategic Research Agenda

The BBSRC-supported Joint Programming Initiative on Agriculture, Food Security and Climate Change (FACCE-JPI) has revised its Strategic Research Agenda, to set out clear research priorities on agriculture, food security and climate change in Europe. Europe has to meet a triple societal challenge of jointly ensuring food security, adaptation to climate change impacts and mitigation of...

Rising temperatures predicted to lower wheat yields

An international consortium of researchers has used big data sets to predict the effects of climate change on global wheat yields. Their multi-model predictions indicated global wheat production losses of 6% for each degree centigrade of global warming with increased variability of yield across regions and seasons. The study has been published in Nature Climate Change. The...

Future air quality could put plants at risk

By combining projections of climate change, emissions reductions and changes in land use across the USA, an international research team estimate that by 2050, cumulative exposure to ozone during the summer will be high enough to damage vegetation. Although the research findings - published in Atmospheric Chemistry and Physics Discussions - focus on the impact in the USA, they...

Meta-analysis study predicts effect of climate change and adaptation on crop yield

In a newly published paper in Nature , a group of NERC funded researchers have performed a meta-analysis of over 1,700 simulation to examine the impact of climate change and adaptation on crop yields of rice, wheat and maize. They conclude that without adaptation of our crops we will face losses in production of all three crops, but with crop adaptation we could potentially increase...

Field study shows why food quality will suffer with rising CO2

For the first time, a field test has demonstrated that elevated levels of carbon dioxide inhibit plants' assimilation of nitrate into proteins, indicating that the nutritional quality of food crops is at risk as climate change intensifies. Findings from this wheat field-test study, led by a UC Davis plant scientist, will be reported online April 6 in the journal Nature Climate...

Climate change puts wheat crops at risk of disease

There is a risk that severity of epidemics of some wheat diseases may increase within the next ten to twenty years due to the impacts of climate change according to a study by international researchers led by the University of Hertfordshire. The researchers carried out a survey in China to establish a link between weather and the severity of epidemics of fusarium ear blight on the wheat...

Climate change may be affecting cultivation of tea

Climate change is reportedly affecting the cultivation of tea in China, with changes in temperatures and rainfall altering not only the taste, aroma, and potential health benefits of the popular beverage but also the lives of farmers who grow tea for a living. A research team headed by Tufts University biologist Colin Orians will study this development in a four-year project funded by a...

Symbiotic fungi may determine the future of soil carbon

When scientists discuss global change, they often focus on the amount of carbon in the atmosphere and vegetation. But soil contains more carbon than air and plants combined. This means that even a minor change in soil carbon could have major implications for the Earth's atmosphere and climate. New research by Smithsonian Tropical Research Institute scientist Benjamin Turner and colleagues at...

New global study reveals how diet and digestion in cows, chickens and pigs drives climate change 'hoofprint'

The resources required to raise livestock and the impacts of farm animals on environments vary dramatically depending on the animal, the type of food it provides, the kind of feed it consumes and where it lives, according to a new study that offers the most detailed portrait to date of "livestock ecosystems" in different parts of the world. The study, published today in...

New report on tackling climate change through livestock

 A new report “ Tackling climate change through livestock ” has concluded that the livestock sector has a large potential to reduce its emissions.  The United Nations’ Food and Agriculture Organisation (FAO) report provides a comprehensive, up to date, global assessment of the livestock sector’s GHG emissions and its mitigation potential. The report can be downloaded...

Report on managing the land in a changing climate

The Adaptation Sub-Committee of the UK's Committee on Climate Change has published a report on "Managing the land in a changing climate" focussing on the use of land to supply food, timber, wildlilfe habitats, carbon storage with the soil and protection from rises in sea levels. The report highlights prioriti areas of increasing the efficiency of water use in agriculture and...

Greenhouse gas could be altering ocean foodchains

Climate change may be weeding out the bacteria that form the base of the ocean’s food chain, selecting certain strains for survival, according to a new study. In climate change, as in everything, there are winners and losers. As atmospheric carbon dioxide levels and temperature rise globally, scientists increasingly want to know which organisms will thrive and which will perish in the...

Parliamentary report on carbon footprint of beef and lamb

A newly-published parliamentary report examining how the carbon footprint of beef and lamb production is measured has been welcomed by the English Beef and Lamb Executive (EBLEX). Sequestration identified as the biggest area of contention While acknowledging the positive environmental impacts that grazing livestock bring, the All Party Parliamentary Group (APPG) for Beef and...

New US – Australian – Indian research collaboration to produce abiotic stress tolerant cereals

As part of the US government’s global hunger and food security initiative, Feed the Future, a new research program is being supported by the US Agency for International  Development (USAID) in partnership with The Australian Centre for Plant  Functional Genomics (ACPFG) and Vibha Agrotech Limited to apply transgenic technologies to  enhance environmental stress tolerance...
